Description

The present invention relates to an information processing system, an information processing device, an information processing method, and a program.

Traditionally, when construction work such as architectural or civil engineering works is carried out, the prime contractor generally places a subcontract order with a first-tier cooperating company, which in turn subcontracts to a second-tier cooperating company, and so on. The construction work is carried out under a hierarchical cooperative relationship.
The Construction Business Act requires prime contractors to post in a conspicuous place on the construction site a construction system diagram that systematically shows the division of labor in a construction project.
The construction system diagram is posted on a signboard on the exterior wall of the construction site, or printed in the office of the construction site. In addition, to ensure the transmission of information, the construction system diagram is printed and handed over to each contractor as appropriate.
In recent years, technology for displaying information using display devices such as digital signage has also come into use at construction sites (see Patent Document 1).

JP 2022-152274 A

However, the content to be recorded in the construction system diagram increases as the scale of the construction work increases, and is also subject to change during the construction work. Therefore, posting the information on a signboard, paper or other medium was not very convenient in terms of visibility of the information or ease of making changes.
Furthermore, even if the construction system diagram is displayed using digital signage, there is a limit to the size of the display screen, and when displayed on different models of digital signage devices, the diagram is not necessarily displayed appropriately on each device, making it difficult to provide sufficient convenience.
In other words, conventional techniques have not provided a high level of convenience for displaying information at construction sites.

The objective of this invention is to improve the convenience of technology for displaying information at construction sites.

In order to solve the above problem, an information processing system according to an embodiment of the present invention comprises:
An information processing system including a signage terminal that electronically displays information, a display management terminal that manages information to be displayed on the signage terminal, and a display information providing server that provides information to be displayed on the signage terminal,
The display management terminal includes:
a requesting means for transmitting a request to the display information providing server for causing the signage terminal to display predetermined information to be displayed at the construction site,
The display information providing server includes:
a display information transmitting means for transmitting display information for displaying predetermined information data to be displayed at the construction site in a display form adapted to each of different types of signage terminals or in different display forms based on a request from the display management terminal;
The signage terminal includes:
The display device is characterized by comprising a display control means for displaying predetermined information to be displayed at the construction site in a display form suitable for each of the different types of signage terminals, or in different display forms, based on the display information.

The present invention can improve the convenience of technology for displaying information at construction sites.

[composition]
[System configuration]
FIG. 1 is a schematic diagram showing the overall system configuration of an information processing system 1 according to the present invention.
Information processing system 1 is a system that displays a construction system diagram to be posted at a construction site using digital signage, and displays the contents of the construction system diagram in an appropriate display format even when different types of digital signage devices are used or when different display formats are required for each digital signage device.
Furthermore, the information processing system 1 makes it possible to create data for displaying a construction system diagram in a simpler procedure.
Therefore, the information processing system 1 can improve the convenience of the technology for displaying information at construction sites.

As shown in FIG. 1, the information processing system 1 includes a prime contractor terminal 10, a display information providing server 20, a display management terminal 30, a signage terminal 40, a system management terminal 50, and an information registration server 60, and these information processing devices are configured to be able to communicate via a network 70. For ease of explanation, FIG. 1 shows only one each of the display information providing server 20, the display management terminal 30, the system management terminal 50, and the information registration server 60, but the information processing system 1 can include multiple of these information processing devices. In addition, the information processing system 1 can include multiple signage terminals 40 of various types. Furthermore, in the following explanation, an example in which the network 70 is configured as the Internet will be described, but as long as each information processing device included in the information processing system 1 is configured to be able to communicate, it can be configured by various networks such as a LAN (Local Area Network) or a VPN (Virtual Private Network).

The prime contractor terminal 10 is a terminal device used by the prime contractor, and performs processes such as notifying each cooperating company and creating and managing a construction system diagram. For example, the prime contractor terminal 10 supplements the information about each cooperating company registered in the information registration server 60 as necessary, or adds and registers information provided by cooperating companies that cannot access the information processing system 1 to the information registration server 60. After information about all cooperating companies related to the construction work is registered in the information registration server 60, the prime contractor terminal 10 instructs the information registration server 60 to create data about the construction system diagram (construction system diagram data by type, described later). In the following, the original data in the information registration server 60 in which information about all cooperating companies is registered will be referred to as "original data" as appropriate.

The display information providing server 20 stores the construction system diagram data (type-specific construction system diagram data described later) sent from the information registration server 60 in a database. The type-specific construction system diagram data is data created from original data according to the type of signage terminal 40 and the display format required for each signage terminal 40, and can be accessed and viewed from the signage terminal 40.

In this embodiment, the type-specific construction system diagram data includes touch panel construction system diagram data created for display on a signage terminal 40 that supports touch operations, and non-touch panel construction system diagram data created for display on a signage terminal 40 that does not support touch operations. These are examples of type-specific construction system diagram data according to the type of signage terminal 40, but it is also possible to prepare type-specific construction system diagram data according to the display form required for each signage terminal 40.
The touch panel construction system diagram data has a data structure that assumes that the viewer will scroll through the entire data by touch operation, and the viewer can freely scroll through the page to display the part that he or she wants to check. However, in the touch panel construction system diagram data, items that are set to be displayed at all times from the viewpoint of importance or visibility (client name, project name, contractor, etc.) are displayed in a fixed manner. In addition, the initial display position is set to the beginning of the construction system diagram (the page that contains various management information related to the entire construction).

In addition, the non-touch panel construction system diagram data has a data structure that assumes that the viewer cannot scroll by touch operation, etc., and a part of the non-touch panel construction system diagram data is automatically scrolled. Specifically, in the non-touch panel construction system diagram data, items that are set to be displayed at all times from the viewpoint of importance or visibility, etc. (client name, project name, contractor, etc.) are displayed fixedly, and the attributes are set so that other items are scrolled. In this embodiment, an attribute is set so that other items are scrolled only vertically. That is, for example, if there are cooperating companies up to the nth level (n is a natural number), the entire hierarchical information from the first cooperating company to the nth cooperating company is displayed horizontally in the scroll area, and by scrolling vertically, it is possible to view the information from the first cooperating company to the nth cooperating company. This type of display format can be realized, for example, by setting a fixed display attribute and a scroll display attribute (automatic scroll display attribute) for each item in non-touch panel construction system diagram data written in HTML (Hyper Text Markup Language) format, and by setting the display width of the item with the scroll display attribute set to the width of the scroll display area.

In the case of construction system diagram data for touch panels, the items that are fixedly displayed and the items that are scrolled are the same as those in construction system diagram data for non-touch panels, but the difference is that the data is scrolled manually rather than automatically. Therefore, in the construction system diagram data for touch panels, the attributes of the data are scrolled (area that is scrolled by manual operation) rather than the attributes of automatic scrolling display.
Moreover, the type-specific construction system diagram data can be configured in various data formats such as the HTML format, the XML (Extensible Markup Language) format, or the PDF (Portable Document Format) format.

In this embodiment, the process of creating type-specific construction system diagram data from original data is described as being executed by the information registration server 60, but the display information providing server 20 may create type-specific construction system diagram data from original data. In this case, the display information providing server 20 can determine the items of the construction system diagram and create it automatically. Note that an editor can also access the display information providing server 20 or the information registration server 60 from the prime contractor terminal 10 or the system management terminal 50 to manually create type-specific construction system diagram data.
Then, when a request is made from the display management terminal 30 to display the construction system diagram on the signage terminal 40, the display information providing server 20 presents to the display management terminal 30 a URL (Uniform Resource Locator) for accessing type-specific construction system diagram data corresponding to the type of signage terminal 40 and the display form required for each signage terminal 40.

FIG. 2 is a schematic diagram showing a display example of construction system diagram data for a non-touch panel.
As shown in FIG. 2, items for which the fixed display attribute is set are fixedly displayed at the top and left end of the screen (fixed display area).
On the other hand, items for which the scroll display attribute is set are displayed in their entirety horizontally in the lower right area of the screen (scroll display area), and are scrolled vertically to display the entirety of the item. In this embodiment, information displayed in the scroll display area is displayed stationary for a predetermined time (e.g., 3 seconds) at the beginning of display, and then scrolled (circulated) from bottom to top at a constant speed.
In the case of the construction system diagram data for touch panel, the scroll display area in FIG. 2 can be freely scrolled up and down.

In the display example shown in Figure 2, blocks representing specific data of cooperating companies are displayed in the scroll display area along with links representing relationships, but because the scroll display area is scrolled vertically (here, from bottom to top), the information is arranged so that the links representing relationships between blocks extend horizontally or downward.
This prevents, for example, secondary cooperating companies from extending upward relative to primary cooperating companies, and only extends downward, thereby preventing a situation in which a viewer viewing the scroll area has to quickly view information that is scrolling out of the display area, or is unable to fully confirm the content.

In other words, it is preferable that the scroll display area be displayed as follows, both for non-touch panel construction system diagram data and for touch panel construction system diagram data, in order to make it easier to visually recognize the hierarchical relationships between cooperating companies when scrolling, in relation to the scrolling direction described above.
For example, cooperating companies at the same hierarchical level (first-level cooperating companies, second-level cooperating companies, ... fifth-level cooperating companies) may be displayed as blocks lined up vertically in the same area (column) in the vertical direction (up and down in Figure 2).
In addition, all or some of the secondary and subsequent cooperating companies that share a common primary cooperating company may be displayed with their blocks aligned horizontally (left and right in FIG. 2) in the same area (row) as the primary cooperating company. In addition, if there are multiple secondary cooperating companies that share a common primary cooperating company, only the block of one of the secondary cooperating companies will be aligned horizontally in the same area (row) as the block of the primary cooperating company.

Furthermore, the display area of the block group created by a primary cooperating company as the first hierarchy (a block group consisting of the blocks of the primary cooperating company and the blocks of secondary or later cooperating companies) may be displayed vertically (up and down in Fig. 2) differently from the display area of the block group created by other primary cooperating companies as the first hierarchy, and this relationship may be the same for secondary and later. For example, if the primary cooperating company is the same but the secondary cooperating companies are different, the display area of the block group created by a secondary cooperating company as the second hierarchy may be displayed vertically (up and down in Fig. 2) differently from the display area of the block group created by other secondary cooperating companies as the second hierarchy. In other words, when expressing the hierarchical relationship between cooperating companies in a tree diagram using blocks and links, the tree diagram is not simply randomly expanded vertically (in Fig. 2), but is displayed so that it extends only in the scrolling direction (downward in Fig. 2), and even if a certain block group has an area where no blocks exist (an area where the specified data of the cooperating company does not exist), the blocks of other block groups are not displayed there (the area where no blocks exist is left as it is). This is because, for example, if a scroll display area is assumed to be scrolled from bottom to top, and a block group is displayed within the display area of a block group, the block of a lower-level cooperating company will be displayed before the block of a higher-level cooperating company in that other area (in relation to the scrolling direction). Since the relationships between cooperating companies in a construction system diagram are usually understood from the higher-level cooperating company to the lower-level cooperating company, it is desirable to prevent the block of a lower-level cooperating company from being displayed before the block of a higher-level cooperating company in relation to the scrolling direction.

Returning to FIG. 1, the display management terminal 30 is used by a contractor (owner) who is to display a construction system diagram on the signage terminal 40, and transmits a request to the display information providing server 20 to display the construction system diagram on the signage terminal 40. In response to the request, the display management terminal 30 also transmits a URL presented by the display information providing server 20 (the URL of the construction system diagram data for touch panel or the URL of the construction system diagram data for non-touch panel) to the signage terminal 40.

The signage terminal 40 displays the specified type-specific construction system diagram data according to the management of the display management terminal 30. Specifically, the signage terminal 40 accesses the URL sent from the display management terminal 30 and displays the touch panel construction system diagram data or the non-touch panel construction system diagram data (or the type-specific construction system diagram data according to the display format required for each signage terminal 40). The type-specific construction system diagram data displayed at this time is selected by the display management terminal 30 according to the type of the signage terminal 40, etc.

The system management terminal 50 manages the entire information processing system 1, registers new prime contractors or partner companies as users, and performs processes for the operation of the information processing system 1. In this embodiment, the system management terminal 50 is capable of manually creating type-specific construction system diagram data from the original data of the construction system diagram (such as editing HTML data). The information processing system 1 may be configured with the system management terminal 50 as a terminal in common with the prime contractor terminal 10.

The information registration server 60 registers information about the prime contractor and each cooperating company related to the construction work in a database. Specifically, the information registration server 60 registers information representing the attributes of the prime contractor and each cooperating company themselves, and information representing the hierarchical relationships between the cooperating companies in the database. In this embodiment, information about the prime contractor and each cooperating company is uploaded by each company to the information registration server 60. Note that with regard to the information about the cooperating companies, a higher-level cooperating company may collectively register information about its lower-level cooperating companies.
In addition, when an instruction to create construction system diagram data (type-specific construction system diagram data) is given after information on all cooperating companies related to the construction work has been registered, the information registration server 60 creates type-specific construction system diagram data. The information registration server 60 then transmits the created type-specific construction system diagram data to the display information providing server 20.

[Hardware configuration]
Next, the hardware configuration of each device in the information processing system 1 will be described.
In the information processing system 1, each device is configured by an information processing device such as a PC, a server computer, a tablet terminal, or a digital signage terminal, and the basic configurations of the devices are the same.

FIG. 3 is a diagram showing the hardware configuration of an information processing device 800 that constitutes each device.
As shown in FIG. 3 , an information processing device 800 constituting each device includes a CPU (Central Processing Unit) 811, a ROM (Read Only Memory) 812, a RAM (Random Access Memory) 813, a bus 814, an input unit 815, an output unit 816, a storage unit 817, a communication unit 818, a drive 819, and an imaging unit 820.

The CPU 811 executes various processes according to a program recorded in the ROM 812 or a program loaded from the storage unit 817 to the RAM 813 .
The RAM 813 also stores data and the like necessary for the CPU 811 to execute various processes.

The CPU 811, ROM 812, and RAM 813 are connected to each other via a bus 814. The input unit 815, output unit 816, memory unit 817, communication unit 818, drive 819, and imaging unit 820 are also connected to the bus 814.

The input unit 815 is made up of various buttons and the like, and is used to input various pieces of information in response to instruction operations.
The output unit 816 is composed of a display, a speaker, etc., and outputs images and sounds.
The storage unit 817 is configured with a hard disk or a dynamic random access memory (DRAM) or the like, and stores various data managed by each server.
The communication unit 818 controls communication with other devices via the network.

Removable media 831, such as a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory, is appropriately loaded into the drive 819. A program read from the removable media 831 by the drive 819 is installed in the storage unit 817 as necessary.
The imaging unit 820 is configured with an imaging device including a lens, an imaging element, etc., and captures a digital image of a subject.
In addition, when the information processing device 800 is configured as the display information providing server 20, it is also possible to omit the imaging unit 820. In addition, when the information processing device 800 is configured as a tablet terminal, it is also possible to configure the input unit 815 with a touch sensor and to provide a touch panel by overlaying it on the display of the output unit 816. In addition, when the information processing device 800 is configured as a signage terminal 40, it mainly functions as a display device, displays display data received from another device, accesses the URL of the display data, and displays a web page. In addition, the hardware configuration of the information processing device 800 can be appropriately changed according to the purpose other than the above-mentioned configuration example, and for example, it is possible to configure the information processing device 800 without the drive 819.

[Functional configuration]
Next, the functional configuration of each device in the information processing system 1 will be described.
[Configuration of the primary contract terminal 10]
FIG. 4 is a block diagram showing the functional configuration of the prime contractor terminal 10. As shown in FIG.
As shown in FIG. 4, in the CPU 811 of the primary contract terminal 10, a UI control unit 111 and a data management unit 112 function.

The UI control unit 111 controls the display of various input/output screens (hereinafter referred to as "UI screens") when the prime contractor's staff performs processes such as notifying each cooperating company or creating and managing a construction system diagram. For example, the UI control unit 111 displays a UI screen for aggregating information for the construction system diagram provided by each cooperating company and preparing it as information to be displayed at the construction site, or for adding information provided by cooperating companies that cannot access the information processing system 1 to the construction system diagram.

After information about all cooperating companies related to the construction work is registered in the information registration server 60, the data management unit 112 instructs the information registration server 60 to create construction system diagram data (construction system diagram data by type).

[Configuration of display information providing server 20]
FIG. 5 is a block diagram showing the functional configuration of the display information providing server 20. As shown in FIG.
5, a construction system diagram data acquisition unit 211, a construction system diagram viewing information presentation unit 212, and a viewing page presentation unit 213 function in a CPU 811 of the display information providing server 20. In addition, a type-specific construction system diagram database (type-specific construction system diagram DB) 221 and a history database (history DB) 222 are formed in a storage unit 817 of the display information providing server 20.

In the type-specific construction system diagram DB221, type-specific construction system diagram data created from original data is stored in association with the original data. When accessed from various terminal devices such as the signage terminal 40, the type-specific construction system diagram data stored in the type-specific construction system diagram DB221 is presented as a viewable web page.

The history DB 222 stores history data of various processes executed by the display information providing server 20 (such as reception history of construction system diagram data by type, viewing history of construction system diagram data by type, etc.).

The construction system diagram data acquisition unit 211 acquires the type-specific construction system diagram data sent from the information registration server 60, associates it with information that identifies the original data (client name, project name, contractor, etc.), and stores it in the type-specific construction system diagram DB 221.

When a request is made from the display management terminal 30 to display the construction system diagram on the signage terminal 40, the construction system diagram viewing information presentation unit 212 transmits display information (URL) to the display management terminal 30 for accessing construction system diagram data (construction system diagram data by type) corresponding to the type of signage terminal 40 and the display format required for each signage terminal 40.
In addition, when a download of actual data (HTML data) for viewing type-specific construction system diagram data as a Web page is requested from the display management terminal 30, the construction system diagram viewing information presentation unit 212 transmits to the display management terminal 30 Web page data of the type-specific construction system diagram data corresponding to the type of signage terminal 40 and the display format required for each signage terminal 40.

The viewing page presenting unit 213 presents the type-specific construction system diagram data stored in the type-specific construction system diagram DB 221 as a Web page in a viewable manner in response to access from various terminal devices such as the signage terminal 40.
In addition, the viewing page presentation unit 213 updates the type-specific construction system diagram data at a set timing. For example, the updating of the type-specific construction system diagram data can be set to "everyday at 2:00 a.m." or "immediately after the date is updated." In this embodiment, the viewing page presentation unit 214 distinguishes (for example, grays out) information on completed processes in the type-specific construction system diagram based on the current date and time and date information (dates and periods for process management, etc.) indicating the progress schedule described in the type-specific construction system diagram data. As a result, as the construction work progresses, the parts related to the completed processes can be automatically distinguished and displayed in the type-specific construction system diagram, so that the progress of the work can be conveyed to the viewer in an easy-to-understand manner.
However, the type-specific construction system diagram data can also be updated sequentially when the original data or type-specific construction system diagram data is updated by the prime contractor terminal 10 or the system management terminal 50 .

In addition to identifying and displaying information on completed processes in the type-specific construction system diagram, it is also possible to not display the parts related to completed processes.
The control of graying out or not displaying (hiding) information on completed processes in these type-specific construction system diagrams can be realized by setting an attribute of "graying out" or "hiding" to the target item by the display information providing server 20. However, the display information providing server 20 may be accessed from the prime contractor terminal 10, and the contractor's staff may manually edit the type-specific construction system diagram.
The viewing page presentation unit 214 terminates the presentation of the type-specific construction system diagram data when a termination condition for terminating the presentation of the type-specific construction system diagram data is met (for example, when the original data is deleted from the information registration server 60, when all construction work processes are completed, when an operation instructing termination is performed from the general contractor terminal 10 or the system management terminal 50, etc.).

[Configuration of display management terminal 30]
FIG. 6 is a block diagram showing the functional configuration of the display management terminal 30. As shown in FIG.
As shown in FIG. 6, in the CPU 811 of the display management terminal 30, a UI control unit 311, a display information request unit 312, and a display information management unit 313 function.
The UI control unit 311 controls the display of an input/output screen (UI screen) when a person in charge of displaying a construction system diagram on the signage terminal 40 performs various processes in the display management terminal 30. For example, when the display information request unit 312 makes a request to display a construction system diagram on the signage terminal 40, the UI control unit 311 displays a request screen for transmitting the contents of the request, and displays a display information presentation screen for displaying the display information transmitted from the display information providing server 20 in response to the request. In addition, when the UI control unit 311 causes the signage terminal 40 managed by the display management terminal 30 to display a construction system diagram by type, the UI control unit 311 displays a list of the signage terminals 40 and displays a display screen for setting display information (URL) of the construction system diagram by type data to be displayed on each signage terminal 40.

The display information request unit 312 transmits a request to the display information providing server 20 to display the type-specific construction system diagram data on the signage terminal 40. In response to this request, a screen displaying the display information transmitted from the display information providing server 20 is displayed by the UI control unit 311, as described above.

FIG. 7 is a schematic diagram showing an example of a request screen for transmitting the contents of a request to the display information providing server 20. As shown in FIG.
The request screen displays a menu for selecting whether or not blank frames are to be displayed in the construction system diagram, and whether the target is a signage terminal 40 that supports touch operation (i.e., whether construction system diagram data for a touch panel is to be requested) or a signage terminal 40 that does not support touch operation (i.e., whether construction system diagram data for a non-touch panel is to be requested). Note that, as an example, a case is shown here where a menu for selecting whether the signage terminal 40 supports touch operation or does not support touch operation is displayed, but the selected menu may be a menu for selecting the display form required for each signage terminal 40 (e.g., color display/monochrome display, whether zoom display is enabled/not enabled, etc.).
The person operating the display management terminal 30 selects an option that suits the purpose from these menus, and then clicks the "Register" button to confirm and transmit the contents of the request.

FIG. 8 is a schematic diagram showing an example of a screen (display information presentation screen) that displays the display information transmitted from the display information providing server 20. As shown in FIG.
As shown in Figure 8, the display information presentation screen displays the selection result of displaying blank frames in the construction system diagram (here, "Display"), the creation status of the construction system diagram by type (here, "Complete"), an access URL for a signage terminal 40 that supports touch operation (URL for viewing construction system diagram data for a touch panel), an access URL for a signage terminal 40 that does not support touch operation (URL for viewing construction system diagram data for a non-touch panel), and two-dimensional codes representing these URLs.

When the display information management unit 313 displays the type-specific construction system diagram on the signage terminal 40 managed by the display management terminal 30, the display information management unit 313 sets the display information (URL) of the type-specific construction system diagram data to be displayed on each signage terminal 40. For example, the display information management unit 313 sets an access URL for a touch-operated signage terminal 40 (a URL for viewing the touch panel construction system diagram data) or an access URL for a touch-operated non-compatible signage terminal 40 (a URL for viewing the non-touch panel construction system diagram data) to each signage terminal 40 in response to the operation of the person in charge. Then, the display information management unit 313 transmits the set URL to each signage terminal 40, and displays the type-specific construction system diagram data, such as the touch panel construction system diagram data or the non-touch panel construction system diagram data, on each signage terminal 40. As described above, type-specific construction system diagram data can be prepared and displayed according to various purposes, such as according to the type of signage terminal 40 and the display format required for each signage terminal 40. Display of blank frames can be achieved by creating type-specific construction system diagram data that displays blank frames and type-specific construction system diagram data that does not display blank frames, and allowing the user to view the one that meets the request. It can also be achieved by adding a code that can control whether to display or hide blank frames to the URL of type-specific construction system diagram data and referencing it, thereby switching the display format of the same type-specific construction system diagram data depending on the reference method.

[Configuration of Signage Terminal 40]
FIG. 9 is a block diagram showing the functional configuration of signage terminal 40. As shown in FIG.
9 , a display information receiving unit 411 and a display control unit 412 function in CPU 811 of signage terminal 40. In this embodiment, signage terminal 40 is equipped with a web browser and displays information provided as a web page. However, signage terminal 40 can be configured to include display means other than a web browser, and may include means for displaying data in XML format or PDF format, for example, and display information provided in these data formats.

The display information receiving unit 411 receives the display information transmitted from the display management terminal 30. The display information receiving unit 411 also passes the URL included in the received display information to the display control unit 412.
The display control unit 412 accesses the URL passed from the display information receiving unit 411, reads the Web page of the construction system diagram by type, and controls the display of the display screen based on the HTML described on the Web page. For example, when the accessed URL is a URL for viewing construction system diagram data for a touch panel, the display control unit 412 displays the Web page without scrolling, and when the viewer performs a touch operation, the display control unit 412 scrolls the Web page in response to the operation. When the accessed URL is a URL for viewing construction system diagram data for a non-touch panel, the display control unit 412 displays items for which the fixed display attribute is set in a fixed manner, and displays items for which the scroll display attribute is set by scrolling from bottom to top (see FIG. 2).

[Configuration of the system management terminal 50]
FIG. 10 is a block diagram showing the functional configuration of the system management terminal 50. As shown in FIG.
As shown in FIG. 10, in a CPU 811 of the system management terminal 50, a UI control unit 511 and a system management unit 512 function.
The UI control unit 511 controls the display of an input/output screen (UI screen) when a person in charge of managing the system performs various processes on the system management terminal 50. For example, the UI control unit 511 displays a display screen for a process of registering a new prime contractor or cooperating company as a user, and various display screens related to the operation of the information processing system 1. The UI control unit 511 also displays a display screen for a process of manually creating type-specific construction system diagram data (e.g., editing HTML data) from the original data registered in the information registration server 60.

The system management unit 512 performs various management operations related to the functions and operations of the information processing system 1. For example, the system management unit 512 monitors the operation status of the display information providing server 20, and if an appropriate response is not returned in response to access from the signage terminal 40, it notifies an alert to the person in charge of managing the system via the UI control unit 512, etc.

[Configuration of information registration server 60]
FIG. 11 is a block diagram showing the functional configuration of the information registration server 60. As shown in FIG.
11, a registration information acquisition unit 611, a database management unit 612, and a type-specific construction system diagram creation unit 613 function in a CPU 811 of the information registration server 60. In addition, a construction work related company database (construction work related company DB) 621 is formed in a storage unit 817 of the information registration server 60.

In the construction work related company DB621, information about the companies (primary contractor and cooperating companies) related to each construction work is stored. The information about the companies related to the construction work includes information that represents the attributes of the primary contractor and each cooperating company themselves, and information that represents the hierarchical relationships between the cooperating companies.

The registration information acquisition unit 611 acquires, as information on companies related to the construction work, information that indicates the attributes of the prime contractor and each cooperating company, and information that indicates the hierarchical relationship between the prime contractor and each cooperating company in the construction work. Information on companies related to the construction work is acquired by the information registration server 60, for example, when each company uploads its own information.
The database management unit 612 associates the information on the companies related to the construction work acquired by the registration information acquisition unit 611 with information for identifying the construction work (such as the name of the construction work) and stores it in the construction work related company DB 621. The information on the companies related to the construction work stored in the construction work related company DB 621 is managed by the prime contractor terminal 10 (person in charge).

The type-specific construction system diagram creation unit 613 creates data on the type-specific construction system diagram when the creation of data on the type-specific construction system diagram is instructed from the prime contractor terminal 10. In this embodiment, after information on all cooperating companies related to the construction work is registered in the information registration server 60, an instruction to create data on the type-specific construction system diagram (data on the type-specific construction system diagram) is sent from the prime contractor terminal 10.
Then, the type-specific construction system diagram creation unit 613 transmits the created type-specific construction system diagram data to the display information providing server 20.

[motion]
Next, the operation of the information processing system 1 will be described.
[Construction system diagram presentation processing]
12 and 13 are flowcharts showing the flow of the construction system diagram presentation process executed by the information processing system 1.
The construction system diagram presentation process is started in response to an instruction to execute the construction system diagram presentation process being input via the input unit 815 of the system management terminal 50 .

When the construction system diagram presentation process is started, in step S1, the type-specific construction system diagram creation unit 613 of the information registration server 60 creates construction system diagram data (type-specific construction system diagram data) in response to an instruction from the prime contractor terminal 10. The created type-specific construction system diagram data is transmitted to the display information providing server 20.
In step S2, the construction system diagram data acquisition unit 211 of the display information providing server 20 receives the type-specific construction system diagram data transmitted from the information registration server 60.

In step S3, the construction system diagram data acquisition unit 211 acquires type-specific construction system diagram data and stores the acquired type-specific construction system diagram data in the type-specific construction system diagram DB 221. At this time, the type-specific construction system diagram data is stored in the type-specific construction system diagram DB 221 in association with information that identifies the original data (client name, project name, contractor, etc.).

In step S4, the construction system diagram data acquisition unit 211 of the display information providing server 20 determines whether or not editing has been performed on the original data of the construction system diagram.
If no editing has been performed on the original data of the construction system diagram, the result of the determination in step S4 is NO, and the process proceeds to step S7.
On the other hand, if editing has been performed on the original data of the construction system diagram, the result of the determination in step S4 is YES, and the process proceeds to step S5.

In step S5, the type-specific construction system diagram creating unit 613 of the information registration server 60 creates type-specific construction system diagram data based on the original data of the edited construction system diagram. The created type-specific construction system diagram data is transmitted to the display information providing server 20.
In step S6, the construction system diagram data acquisition unit 211 of the display information providing server 20 updates the type-specific construction system diagram data received from the information registration server 60.
After step S6, the process proceeds to step S3.

In step S7, the browsing page presenting unit 214 of the display information providing server 20 judges whether or not it is time to update the type-specific construction system diagram data.
If the timing set for updating the type-specific construction system diagram data has not arrived, the result of step S7 is determined to be NO, and the process proceeds to step S9.
On the other hand, if it is the timing set for updating the type-specific construction system diagram data, the result of the determination in step S7 is YES, and the process proceeds to step S8.

In step S8, the browsing page presenting unit 214 of the display information providing server 20 updates the type-specific construction system diagram data according to the set update timing.
In step S9, the browsing page presenting unit 214 determines whether or not the end condition for the construction system diagram presenting process is met.
If the termination condition for the construction system diagram presentation process is met, a YES determination is made in step S9, and the construction system diagram presentation process ends.
On the other hand, if the termination condition for the construction system diagram presentation process is not met, a NO result is obtained in step S9, and the process proceeds to step S10.

In step S10, the UI control unit 311 of the display management terminal 30 determines whether or not an operation has been performed to display the construction system diagram on the signage terminal 40 by the person in charge of displaying the construction system diagram on the signage terminal 40.
If the person in charge of displaying the construction system diagram on the signage terminal 40 has not performed any operation to display the construction system diagram on the signage terminal 40, the result is determined to be NO in step S10, and processing proceeds to step S7.
On the other hand, if an operation to display the construction system diagram on the signage terminal 40 is performed by a person in charge of displaying the construction system diagram on the signage terminal 40, the result is determined to be YES in step S10, and processing proceeds to step S11.

In step S<b>11 , the UI control unit 311 of the display management terminal 30 displays a request screen for transmitting the contents of a request to the display information providing server 20 .
In step S12, the UI control unit 311 of the display management terminal 30 accepts input to the request screen. At this time, whether or not to display blank frames in the construction system diagram, whether the signage terminal 40 that supports touch operation is the target (i.e., whether to request construction system diagram data for a touch panel)/whether or not the signage terminal 40 that does not support touch operation is the target (i.e., whether to request construction system diagram data for a non-touch panel), and the like are selected.

In step S13, the UI control unit 311 of the display management terminal 30 determines whether or not an operation has been performed to confirm and transmit the contents of the request.
If an operation for confirming and transmitting the contents of the request has not been performed, the result of the determination in step S13 is NO, and the process proceeds to step S12.
On the other hand, if an operation for confirming and transmitting the contents of the request has been performed, then the determination in step S13 is YES, and the process proceeds to step S14.

In step S<b>14 , the display information requesting unit 312 transmits a request for displaying the construction system diagram on the signage terminal 40 to the display information providing server 20 .
In step S15, the construction system diagram viewing information presentation unit 213 transmits display information (URL) for accessing construction system diagram data (construction system diagram data by type) corresponding to the type of signage terminal 40 to the display management terminal 30.

In step S16, the construction system diagram viewing information presentation unit 213 determines whether or not a request has been made from the display management terminal 30 to download actual data (HTML data) for viewing the type-specific construction system diagram data as a Web page.
If there is no request from the display management terminal 30 to download the actual data (HTML data) for viewing the type-specific construction system diagram data as a Web page, the result is judged as NO in step S16 and processing proceeds to step S18.
On the other hand, if a request is made from the display management terminal 30 to download the actual data (HTML data) for viewing the type-specific construction system diagram data as a Web page, the answer is determined as YES in step S16 and processing proceeds to step S17.

In step S<b>17 , the construction system diagram view information presenting unit 213 transmits Web page data of the type-specific construction system diagram data corresponding to the type of signage terminal 40 to the display management terminal 30 .
In step S18, the construction system diagram viewing information presentation unit 213 determines whether or not access from the display management terminal 30 has been completed.
If the access from the display management terminal 30 has not been completed, the result of the determination in step S18 is NO, and the process proceeds to step S16.
On the other hand, if the access from the display management terminal 30 is completed, the determination in step S18 is YES, and the process proceeds to step S4.

Through such processing, the information processing system 1 according to this embodiment acquires (creates or receives) type-specific construction system diagram data based on the original data of the construction system diagram.
Then, when a request is made from the display management terminal 30 to display the construction system diagram on the signage terminal 40, the display information providing server 20 transmits any or all of the type-specific construction system diagram data to the display management terminal 30, depending on the selection indicated in the request from the display management terminal 30.

The display management terminal 30 transmits display information (URL) to each signage terminal 40 for accessing one of the type-specific construction system diagram data (construction system diagram data for touch panels or construction system diagram data for non-touch panels, etc.) depending on the type of signage terminal 40 that displays the construction system diagram.
As a result, each signage terminal 40 displays type-specific construction system diagram data in different display formats, such as a construction system diagram in which parts scroll automatically or a construction system diagram that scrolls by touch operation, depending on the type of signage terminal 40, such as whether it is touch-operation incompatible or touch-operation compatible, and the display format required for each signage terminal 40.
Therefore, it is possible to improve the convenience of the technology for displaying information (construction system diagrams) at construction sites.

[Modification 1]
In the above embodiment, a description has been given of creating a plurality of types of construction system diagram data according to the type of signage terminal 40 and the display form required for each signage terminal 40 from original data, but this is not limited to the above.
That is, a single construction system diagram data (actual data) that can support a plurality of display forms can be created, and in the single construction system diagram data, attributes related to the scroll display can be set for items that are the subject of scroll display. Then, by adding a code capable of controlling the scroll display (control information for enabling/disabling the scroll display attribute) to the URL of the construction system diagram data and referencing it, the display form of the same construction system diagram data can be switched depending on the reference method.
For example, in the non-touch panel construction system diagram data shown in FIG. 2, an attribute for automatic scrolling display is set for some items (items displayed in the lower right corner of the screen).
In the URL for referencing the non-touch panel construction system diagram data shown in FIG. 2, a control code for disabling the scroll display attribute (for example, "-scrolloff") can be added to the end.
As a result, when the signage terminal 40 refers to the construction system diagram data for non-touch panels, the data is read with the scroll attribute set as invalid, and even if the construction system diagram data for non-touch panels is read, the display format does not include automatic scrolling.
With this method, construction system diagram data can be displayed in different display formats by switching the reference method for the same construction system diagram data, without having to create type-specific construction system diagram data corresponding to various display formats.
Therefore, even with this method, an appropriate display form can be realized depending on the type of signage terminal 40 and the display form required for each signage terminal 40 .
In other words, it is possible to improve the convenience of the technology for displaying information (construction system diagrams) at construction sites.
Note that, although attributes related to scrolling display have been used as an example here, attributes other than scrolling display (e.g., attributes related to color display, character size display, animation display, etc.) may also be enabled/disabled using a control code.

As described above, the information processing system 1 according to this embodiment includes the prime contractor terminal 10, the display information providing server 20, the display management terminal 30, the signage terminal 40, and the system management terminal 50.
The display management terminal 30 transmits a request for causing the signage terminal 40 to display predetermined information to the display information providing server 20 .
Based on a request from the display management terminal 30, the display information providing server 20 transmits display information that displays specific information data to be displayed at the construction site in a display form suitable for each of the different types of signage terminals 40, or in different display forms.
Based on the display information, the signage terminal 40 displays predetermined information to be displayed at the construction site in a display format suitable for each of different types of signage terminals or in different display formats.
Therefore, display information for accessing type-specific data corresponding to the type of signage terminal 40 or display information for displaying specific information to be displayed at a construction site in different display formats regardless of the type of signage terminal 40 can be easily set on each signage terminal 40.
Therefore, it is possible to improve the convenience of the technology for displaying information at construction sites.

Based on a request from the display management terminal 30, the display information providing server 20 transmits display information so that type-specific data adapted to a form corresponding to different types of signage terminals 40 can be displayed on the signage terminal 40, in which the data of specific information to be displayed at the construction site is transmitted.
The signage terminal 40 displays the specified information to be displayed at the construction site in a display format suitable for the signage terminal 40 based on the type-specific data.
This makes it possible to display specific information to be displayed at the construction site in an appropriate display format on each signage terminal 40 based on type-specific data that is suited to the type of signage terminal 40 .

Based on a request from the display management terminal 30, the display information providing server 20 transmits display information including the storage location of entity data including attribute information that sets the display format when specific information data to be displayed at the construction site is displayed, and control information that specifies whether the attribute information is valid or invalid.
The signage terminal 40 displays actual data based on the storage location in the display information, and by enabling or disabling attribute information set in the actual data in accordance with the control information, displays specified information to be displayed at the construction site in a display format corresponding to the control information.
This makes it possible to change the display format for displaying a single piece of actual data depending on the reference method used when referencing the storage location of the single piece of actual data.
Therefore, an appropriate display form can be realized depending on the type of signage terminal 40 and the display form required for each signage terminal 40 .

The type-specific data includes data of specific information for scrolling display, at least a portion of which scrolls automatically, and data of specific information for non-scrolling display, which is not automatically scrolled but is scrolled in response to an operation.

The data for the specified information for scrolling display is data that is displayed in a form that scrolls only in one of the vertical and horizontal directions on the display screen, and information that extends in the non-scrolling direction is displayed within the range of the scroll area.

Upon request, the display information providing server 20 transmits display information for type-specific data corresponding to all different types of signage terminals 40.

The display information providing server 20 transmits information indicating the storage location (URL) of the type-specific data based on a request from the display management terminal 30.

The display information providing server 20 transmits the actual data by type based on a request from the display management terminal 30.

The display information providing server 20 updates the type-specific data at the set timing.

The display information providing server 20 identifies and displays information on completed processes in the specified information based on the current date and time and date information indicating the progress schedule described in the specified information to be displayed at the construction site.

The display information providing server 20 updates the specified information so that information on completed processes is not displayed based on the current date and time and the date information indicating the progress schedule that is included in the specified information to be displayed at the construction site.

The type-specific data includes attribute information that identifies and displays information about completed processes in the specified information based on the current date and time and date information indicating the progress schedule listed in the specified information to be displayed at the construction site.

The type-specific data includes attribute information that indicates that information on completed processes will no longer be displayed in the specified information, based on the current date and time and date information indicating the progress schedule that is listed in the specified information to be displayed at the construction site.

The present invention is not limited to the above-described embodiment, and modifications and improvements within the scope of the present invention that can achieve the object of the present invention are included in the present invention.
For example, the system configuration of the information processing system 1 in the above embodiment is an example, and as long as the functions of the information processing system 1 are realized as a whole, it is possible to distribute and implement the functions on more servers. In addition, it is also possible to implement the functions of multiple information processing devices in the information processing system 1 together in a smaller number of information processing devices, and for example, it is also possible to implement the functions of terminal devices such as the prime contractor terminal 10, the display management terminal 30, and the system management terminal 50 in one terminal device.
In addition, the information processing system 1 in the above-described embodiment can be realized as a cloud system using a cloud server, or as an on-premise system using an on-premise server, or can be realized as a combination of these.

Furthermore, in the above-described embodiment, when the scroll display area is enlarged or reduced, the information spreading in the non-scrolling direction remains within the range of the scroll area, while all objects, such as blocks, contained in the scroll display area can be enlarged or reduced at the same ratio.
This eliminates the need to individually adjust the vertical and horizontal ratios of objects when creating type-specific construction system diagram data from original construction system diagram data, and makes it easy to create type-specific construction coordination diagram data suited to signage terminals 40 of various sizes.
In the above embodiment, the information in the scroll display area is scrolled vertically (from bottom to top), but this is not limiting. That is, the information in the scroll display area may be scrolled horizontally (from left to right or from right to left).

The above-described series of processes can be executed by hardware or software.
In other words, the functional configurations in the above-described embodiments are merely examples and are not particularly limited. That is, it is sufficient that any of the computers constituting the information processing system 1 has a function capable of executing the above-described series of processes as a whole, and the type of functional block used to realize this function is not particularly limited to the examples shown.
Furthermore, one functional block may be configured as a single piece of hardware, a single piece of software, or a combination of both.

The recording medium containing the program for executing the above-mentioned series of processes may be configured not only as a removable medium distributed separately from the device body in order to provide the program to the user, but also as a recording medium etc. provided to the user in a state where it is already installed in the device body.

Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment. Furthermore, the effects described in this embodiment are merely a list of the most favorable effects resulting from the present invention, and the effects of the present invention are not limited to those described in this embodiment.
