Description

The present invention relates to data backup.

For example, various devices such as water supply devices may have variable parameters set at the time of installation. By setting appropriate parameters for the device, it is possible to make the device operate in a manner suitable for the usage environment. Then, even after the replacement of the device or its parts (for example, the control board or the electrical component including the control board), the parameters before the replacement may be continuously set. In addition, for example, when a malfunction occurs in a device, a worker may adjust the parameters of the device, but when it is found that the parameters after adjustment are inappropriate, the parameters before adjustment are used in the device. It may be reset.

However, conventionally, the parameters set in the device have been managed in various ways. For example, a label with parameters may be affixed to the device, it may be recorded as a separate document from the device or electromagnetically, or it may not be managed at all in the first place. If the parameter management method is not unified in this way, the worker can efficiently identify the parameters set in the equipment when necessary, for example, when replacing the equipment or its parts or when adjusting the parameters. It is expected to be difficult. Therefore, it is desirable to manage the parameters of the equipment in a unified manner.

Patent Document 1 discloses a technique for backing up / restoring data for an MFP (Multifunction Peripheral). Specifically, according to [0021] of Patent Document 1, the data backup servers 400A to 400C have a storage device 403 that stores backup information a1 to a3 acquired from the MFP100 side, and backup information a1 to 1. The a3 includes device-specific information for identifying the MFP 100 and backup (specific) data having the identification information. That is, according to the technique of Patent Document 1, it is possible to uniformly manage a large number of backup data of the MFP 100 by the data backup servers 400A to 400C.

JP-A-2018-84944

Patent Document 1 does not assume that the MFP 100 or its parts are replaced, let alone the backup data before the replacement is taken over after the replacement. If the MFP 100 or its component having certain device-specific information is replaced with an MFP or component having different device-specific information, the backup data corresponding to the former device-specific information is immediately acquired from the latter device-specific information. You can't.

An object of the present invention is to automatically take over and manage backup data of a device even after the device or its parts are replaced.

The backup server according to one aspect of the present invention includes a first storage unit, a second storage unit, a first acquisition unit, and a registration unit. The first storage unit stores the identification data in association with the key data. The second storage unit stores the key data in association with the backup data. The first acquisition unit acquires an initial setting request including the first identification data and the second identification data different from the first identification data. In response to the initial setting request, the registration unit associates the second identification data with the first key data, which is the key data associated with the first identification data in the first storage unit, and stores the second identification data in the first storage unit. Register with the department.

A backup server according to another aspect of the present invention includes a storage unit, an acquisition unit, and a registration unit. The storage unit stores the identification data in association with the backup data. The acquisition unit acquires an initial setting request including the first identification data and the second identification data different from the first identification data. In response to the initial setting request, the registration unit registers the second identification data in the storage unit in association with the first backup data which is the backup data associated with the first identification data in the storage unit.

Hereinafter, elements that are the same as or similar to the elements described will be designated by the same or similar reference numerals, and duplicate explanations will be basically omitted. For example, when a plurality of the same or similar elements exist, a common code may be used to explain each element without distinction, and the common code may be used to explain each element separately. In addition, the branch number may be used.

In the following description, for convenience, the device to be backed up is assumed to be a water supply device, but the device is not limited to the water supply device. For example, the device may be a pumping device for any purpose such as pumping, drainage, compression, etc., and various electrical or mechanical equipment other than the pumping device, such as a computer, OA (Office Automation) equipment, home appliances, etc. It may be a robot, an industrial machine, or the like.

(First Embodiment)
As illustrated in FIG. 1, the backup system according to the first embodiment includes a backup server 100, terminals 200-1, 200-2, 200-3, ..., And water supply devices 300-1,300. -2, 300-3, 300-4, 300-5, 300-6, ...

The number of each device in FIG. 1 is merely an example. For example, the backup server 100 may be made redundant as a plurality of servers, and since the number of terminals 200 and the water supply device 300 is arbitrary, the number of terminals 200 may be more or less than three. , The number of water supply devices 300 may be more or less than six.

The terminal 200 can be connected to the backup server 100 via a network using wireless communication technology such as mobile communication (for example, 3G, 4G, 5G, mobile WiMAX), wireless LAN (Local Area Network), WiMAX, and the like. .. Further, the terminal 200 uses a (short-range) wireless communication technology such as Bluetooth (registered trademark), wireless LAN, NFC (Near Field Communication), or a wired communication technology such as USB (Universal Serial Bus) to supply the water supply device 300. Can be connected to.

The terminal 200 requests the water supply device 300 for identification data for identifying the water supply device 300 (or a component such as a control board thereof), or requests backup data such as parameters set in the water supply device 300. A data acquisition command is issued to send the data acquisition command to the water supply device 300. The terminal 200 issues various requests to the backup server 100 based on the data received from the water supply device 300.

Then, the terminal 200 transmits a backup request described later to the backup server 100 to register the backup data of the water supply device 300, and sends a search request described later to the backup server 100 to restore the parameters of the water supply device 300. Or, in order to take over the backup data registered for the water supply device 300 even after the replacement of the water supply device 300 or its parts, an initial setting request described later is transmitted to the backup server 100.

Further, when restoring data such as parameters of the water supply device 300, the terminal 200 receives backup data including the parameters of the water supply device 300 from the backup server 100 as a response to the search request, and sends these parameters to the water supply device 300. A parameter setting command for setting may be issued and transmitted to the water supply device 300.

The backup server 100 manages backup data for each water supply device 300. Specifically, the backup server 100 registers the backup data of the terminal 200 in the internal database in response to the backup request received from the terminal 200, and the water supply device 300 corresponding to the search request received from the terminal 200. The backup data is searched from this database and returned to the terminal 200, or the identification data of the new (for example, after replacement) water supply device 300 is used for the existing (for example, before replacement) water supply device in response to the initial setting request received from the terminal 200. Associate with 300 identification data. In this way, since the "initial setting" associates the two identification data, it can also be called a "link setting" or the like.

Specifically, the backup server 100 according to the first embodiment associates the backup data of the water supply device 300 with the first database associated with the key data for indexing, and the key data with the identification data of the water supply device 300. We are building a second database. The initial setting request includes the link source identification data registered in the second database and the link destination identification data newly associated with the link source identification data, as will be described later. The backup server 100 searches the second database for the key data associated with the link source identification data included in the initial setting request, and associates the link destination identification data included in the initial setting request with the key data for the second. Register in the database of. Therefore, after the initial setting request is processed normally, when the backup server 100 receives the search request including the link destination identification data, it is the same as the key data associated with the link source identification data from the second database. It is possible to search the key data of the above, search the backup data of the water supply device 300 associated with this key data, that is, identified by the link source identification data, from the first database, and return it to the terminal 200. That is, even after the water supply device 300 or its component identified by the link source identification data is replaced with the water supply device 300 or its component identified by the link destination identification data, the backup data of the former water supply device 300 is inherited. Can be done.

The water supply device 300 includes an electrical component including a storage unit as described later, and identification data of the water supply device 300 is written in the storage unit at the time of manufacturing, shipping, delivery, or the like, for example. There is. Then, the water supply device 300 reads out its own identification data, data to be backed up to the backup server 100 (for example, set parameters), and the like from the storage unit in response to a data acquisition command from the terminal 200, for example. Send to terminal 200. Further, the water supply device 300 receives a command such as a parameter setting command from the terminal 200, and sets, for example, a parameter according to the command.

Hereinafter, the configurations and operations of the backup server 100, the terminal 200, and the water supply device 300 in FIG. 1 will be described in order with reference to the drawings.
First, a configuration example of the backup server 100 will be described. The backup server 100 is, for example, a server computer. The backup server 100 processes a request from the terminal 200, that is, registers and retrieves backup data, associates identification data with each other (that is, sets a link), and the like (for example, a CPU (Central Processing Unit)), an FPGA ( Field Programmable Gate Array), ASIC (Application Specific Integrated Circuit), etc.) are included. Further, the backup server 100 includes a memory for temporarily storing a program executed by the processor and data used by the processor to realize such processing.

The backup server 100 can further use a communication I / F (interface) for connecting to an external device. The communication I / F may be built in the backup server 100 or externally attached to the backup server 100.

The communication I / F communicates with the terminal 200 via a network, typically the Internet. The communication I / F receives various requests from the terminal 200 and transmits a response to the requests to the terminal 200.

The backup server 100 can also use an auxiliary storage device for accumulating data. The auxiliary storage device may be built in the backup server 100 or may be externally attached to the backup server 100.

The auxiliary storage device stores, for example, identification data, key data, backup data, and the like registered based on a request received from the terminal 200 or another communication device (not shown). The auxiliary storage device is preferably a non-volatile storage medium such as an HDD (Hard Disk Drive), an SSD (Solid State Drive), or a flash memory. Alternatively, the auxiliary storage device may be a file server connected to the backup server 100 via a network.

The backup server 100 can further use an input I / F for accepting user input. The input I / F may be built in the backup server 100 or externally attached to the backup server 100.

The input I / F may be, for example, a keyboard, a mouse, a numeric keypad, a microphone, a camera, or the like, or may have an output I / F function such as a touch screen. User input can typically be tap, click, drag, press of a particular key, and so on. In addition, the user input can also include, for example, voice captured by a microphone.

Next, the description of the configuration example of the backup server 100 will be continued with reference to FIG. The backup server 100 of FIG. 2 includes an initial setting request acquisition unit 101, a backup request acquisition unit 102, a search request acquisition unit 103, a data registration unit 104, a key data storage unit 105, and a backup data storage unit 106. It includes a data search unit 107 and a request response unit 108.

The initial setting request acquisition unit 101 acquires an initial setting request. The initial setting request includes the link source identification data registered in the database constructed in the key data storage unit 105 and the link destination identification data different from the link source identification data. The initial setting request can typically be issued when the water supply device 300 (or parts such as its electrical components) is replaced, in which case the link source identification data is data that identifies the water supply device 300 before replacement. , The link destination identification data is data for identifying the water supply device 300 after replacement. The initial setting request acquisition unit 101 may receive the initial setting request from the terminal 200, and acquires the initial setting request based on, for example, user input such as key input, reading of an image (including a barcode), and the like. It is possible to do. That is, the initial setting request acquisition unit 101 may correspond to the above-mentioned communication I / F and / or input I / F. The initial setting request acquisition unit 101 sends an initial setting request to the data registration unit 104.

The identification data included in the various requests may be hashed. Thereby, even if the data stored in the key data storage unit 105 and / or the backup data storage unit 106 is leaked for some reason, it is possible to identify which water supply device 300 the individual backup data belongs to. Can be prevented.

The backup request acquisition unit 102 acquires a backup request. The backup request includes identification data and backup data. The backup request can typically be issued at the first installation of the water supply device 300, at the time of changing the parameters of the water supply device 300, and the like. The backup request acquisition unit 102 may receive the backup request from the terminal 200, or may acquire the backup request based on, for example, user input such as key input, reading of an image (including a barcode), or the like. possible. That is, the backup request acquisition unit 102 may correspond to the above-mentioned communication I / F and / or input I / F. The backup request acquisition unit 102 sends a backup request to the data registration unit 104.

The search request acquisition unit 103 acquires a search request. The search request includes identification data. The search request can typically be issued at the time of data recovery such as parameters of the water supply device 300. The search request acquisition unit 103 receives a search request from, for example, the terminal 200. That is, the search request acquisition unit 103 may correspond to the above-mentioned communication I / F. The search request acquisition unit 103 sends a search request to the data search unit 107.

The data registration unit 104 may correspond to the above-mentioned processor. The data registration unit 104 registers data (entry) in the database constructed in the key data storage unit 105 and / or the backup data storage unit 106 in response to various requests such as an initial setting request and a backup request. ..

The data registration unit 104 receives an initial setting request from the initial setting request acquisition unit 101. The data registration unit 104 searches for the first key data, which is the key data associated with the link source identification data included in the initial setting request, from the database constructed in the key data storage unit 105. Then, the data registration unit 104 associates the link destination identification data included in the initial setting request with the first key data and registers it in the database (that is, registers it in the key data storage unit 105).

Specifically, the key data storage unit 105 may store a key data table (DB) including entries e11, e12, e13, ..., As illustrated in FIG. Here, it is assumed that the initial setting request includes id_b1 as the link source identification data and id_b2 as the link destination identification data. In this case, the data registration unit 104 searches the key data table for key_2, which is the key data associated with id_b1 as the link source identification data. Then, the data registration unit 104 duplicates this key data, associates id_b2 as the link destination identification data with this, and registers it as a new entry in the above table. This makes it possible to search and restore the backup data of the water supply device 300 identified by id_b1 as the link source identification data based on id_b2 as the link destination identification data.

If the initial setting request is received from any of the terminals 200, the data registration unit 104 issues an initial setting completion notification as a response to the initial setting request after the registration of the link destination identification data is completed. It may be sent to the request response unit 108. Alternatively, after the registration of the link destination identification data is completed, the data registration unit 104 reads out the backup data associated with the first key data in the database constructed in the backup data storage unit 106 as a response to the initial setting request. , May be sent to the request response unit 108. According to the latter response, the terminal 200 can acquire the backup data of the water supply device 300 identified by the link destination identification data without issuing a search request. This is useful, for example, when replacing the water supply device 300, in addition to taking over the backup data, setting the parameters of the water supply device 300 before the replacement in the water supply device 300 after the replacement.

The data registration unit 104 receives a backup request from the backup request acquisition unit 102. First, the data registration unit 104 searches the database built in the key data storage unit 105 for the key data associated with the identification data included in the backup request. Then, when the search is successful, the data registration unit 104 associates the backup data included in the backup request with the key data and registers it in the database constructed in the backup data storage unit 106 (that is, backup data storage). Register in part 106).

On the other hand, if the search fails, specifically, if the identification data included in the backup request is not registered in the database constructed in the key data storage unit 105, the data registration unit 104 is stored in this database. A new key data different from any registered key data can be issued, and this identification data can be associated with the new key data and registered in this database.

When the backup request is received from any of the terminals 200, the data registration unit 104 issues a backup completion notification as a response to the backup request after the registration of the backup data is completed, and sends the backup completion notification to the request response unit 108. You may send it.

The key data storage unit 105 stores the identification data in association with the key data. For example, the key data storage unit 105 may store the identification data and the key data in a table format. This table can also be called a database. In the key data storage unit 105, each identification data is associated with one key data. That is, none of the identification data is associated with the plurality of key data. On the other hand, in the key data storage unit 105, the key data may be duplicated with a plurality of identification data. The key data storage unit 105 may correspond to the memory and / or auxiliary storage device described above.

The key data storage unit 105 may write identification data and key data by the data registration unit 104. Further, the data stored in the key data storage unit 105 can be read out by the data registration unit 104 and the data search unit 107 (including the search).

The backup data storage unit 106 stores the key data in association with the backup data. For example, the backup data storage unit 106 may store the key data and the backup data in a table format. This table can also be called a database. Specifically, the backup data storage unit 106 may store a backup data table (DB) including entries e21, e22, e23, ..., As illustrated in FIG. The backup data storage unit 106 may correspond to the memory and / or auxiliary storage device described above. Here, the backup data is not limited to the backup data main body, and may be data indicating the location of the backup data main body such as a URL (Uniform Resource Locator).

The backup data storage unit 106 may write key data and backup data by the data registration unit 104. Further, the data stored in the backup data storage unit 106 can be read out by the data registration unit 104 and the data search unit 107 (including the search).

The data search unit 107 may correspond to the above-mentioned processor. The data search unit 107 responds to various requests such as search requests from the database constructed in the key data storage unit 105 and / or the backup data storage unit 106, and displays data for indexing, such as identification data and key data. Search for data associated with, etc.

The data search unit 107 receives a search request from the search request acquisition unit 103. First, the data search unit 107 searches the key data associated with the identification data included in the search request from the database constructed in the key data storage unit 105. Further, the data search unit 107 searches the backup data associated with the key data from the database constructed in the backup data storage unit 106.

If the search request is received from any of the terminals 200, the data search unit 107 may send the backup data to the request response unit 108 as a response to the search request after the backup data search is completed. Good.

The request response unit 108 receives responses to various requests originating from the terminal 200 from the data registration unit 104 or the data search unit 107, and returns the responses to the terminal 200 (that is, transmits the response to the terminal 200 via the network). ). The request response unit 108 may correspond to the above-mentioned communication I / F.

For example, the request response unit 108 may receive the initial setting completion notification or backup data from the data registration unit 104 and return this to the terminal 200 as a response to the initial setting request. The backup data here is backup data associated with a certain key data in the database constructed in the backup data storage unit 106, and this key data is initially used in the database constructed in the key data storage unit 105. It is associated with the link source identification data included in the setting request.

Further, the request response unit 108 may receive a backup completion notification from the data registration unit 104 and return this to the terminal 200 as a response to the backup request.

Further, the request response unit 108 may receive backup data from the data search unit 107 and return the backup data to the terminal 200 as a response to the search request. The backup data here is backup data associated with a certain key data in the database constructed in the backup data storage unit 106, and this key data is searched in the database constructed in the key data storage unit 105. It is associated with the identification data contained in the request.

The terminal 200 can further use a communication I / F for connecting to an external device. The communication I / F may be built in the terminal 200 or may be externally attached to the terminal 200.

The communication I / F communicates with the backup server 100 via a network, typically the Internet, using communication technologies such as mobile communication, wireless LAN, and WiMAX. The communication I / F transmits various requests to the backup server 100, and receives a response to the requests from the backup server 100.

Further, the communication I / F communicates with the water supply device 300 by using (short-range) wireless communication technology or wired communication technology. The communication I / F sends various commands to the water supply device 300, and receives a response (for example, identification data and / or backup data) from the water supply device 300 to the command from the water supply device 300.

The communication I / F for connecting to the backup server 100 may be common to or different from the communication I / F for connecting to the water supply device 300. For example, the former may be a 4G module and the latter may be a Bluetooth module.

The terminal 200 can also use an auxiliary storage device for accumulating data. The auxiliary storage device may be built in the terminal 200 or may be externally attached to the terminal 200.

The auxiliary storage device can store various data, for example, a local database (DB) described later. By using such a local DB, even in a situation where it is difficult for the terminal 200 to connect to the backup server 100, for example, when the water supply device 300 is installed underground, a restoration process based on data downloaded in advance from the backup server 100 is performed. , Etc. are possible.

The terminal 200 can further use an input I / F for accepting user input. The input I / F may be built in the terminal 200 or may be externally attached to the terminal 200.

The identification data acquisition unit 201 may receive the identification data from the water supply device 300, and acquires the identification data based on, for example, user input such as key input, reading of an image (including a barcode), or the like. There can also be. That is, the identification data acquisition unit 201 may correspond to the above-mentioned communication I / F and / or input I / F. The water supply device 300 may transmit its own identification data in response to an identification data acquisition command from the terminal 200, and may spontaneously transmit its own identification data, such as a beacon signal in wireless communication technology. Alternatively, the terminal 200 may display it in a readable format. The identification data acquisition unit 201 sends the identification data to the request issuing unit 203.

The backup data acquisition unit 202 acquires backup data such as parameters set in the water supply device 300. The backup data acquisition unit 202 may receive backup data from the water supply device 300, and acquires backup data based on user input such as key input, reading of an image (including a barcode), and the like. There can also be. That is, the backup data acquisition unit 202 may correspond to the above-mentioned communication I / F and / or input I / F.

The request issuing unit 203 may receive the identification data from the identification data acquisition unit 201 and the backup data from the backup data acquisition unit 202. The request issuing unit 203 issues various requests based on the received data. For example, the request issuing unit 203 issues an initialization request based on the identification data of two different water supply devices 300, issues a backup request based on the identification data and backup data of a certain water supply device 300, and issues a certain water supply. A search request is issued based on the identification data of the device 300.

For example, the communication unit 204 may send backup data (which may include parameters configurable to the water supply device 300) as a response to a transmitted initialization request or search request to the command issuing unit 205.

Further, the communication unit 204 may receive (download) the data to be stored in the local DB storage unit 208 from the backup server 100 and send it to the local DB management unit 207. For example, in order to restore data such as parameters in an offline environment, some or all of the database entries constructed in the key data storage unit 105 and the backup data storage unit 106 of the backup server 100 are preliminarily made by the terminal 200. Can be downloaded.

The command issuing unit 205 issues various commands for controlling the water supply device 300 and sends them to the command transmitting unit 206. For example, the command issuing unit 205 may receive backup data including parameters from the communication unit 204 as a response to a transmitted initialization request or search request. Then, the command issuing unit 205 may issue a parameter setting command for setting this parameter in the water supply device 300. Here, the water supply device 300 is identified by the link destination identification data included in the initial setting request or the identification data included in the search request. Further, the command issuing unit 205 may issue an identification data / backup data acquisition command in order for the identification data acquisition unit 201 and / or the backup data acquisition unit 202 to acquire the identification data and / or the backup data. The command issuing unit 205 may correspond to the above-mentioned processor.

The command transmission unit 206 receives a command from the command issuing unit 205 and transmits the command to the water supply device 300. The command transmission unit 206 may correspond to the above-mentioned communication I / F.

The local DB management unit 207 reads and writes to the local DB storage unit 208. The local DB management unit 207 may correspond to the above-mentioned processor.

Can be written to the local DB storage unit 208 as a local DB. By using such a local DB, the local DB management unit 207 can respond to the search request issued by the request issuing unit 203 even in an offline environment, for example, and the backup data as a response can be used as a command issuing unit. Can be returned to 205.

A part or all of the database constructed in the key data storage unit 105 and the backup data storage unit 106 of the backup server 100 may be transplanted to the local DB storage unit 208.

The local DB storage unit 208 may correspond to the memory and / or auxiliary storage device described above.

Next, a configuration example of the water supply device 300 will be described. The water supply device 300 has a built-in electrical component. This electrical component may be replaceable independently. That is, it may be possible to replace only the electrical components with new ones while maintaining other mechanical or electrical elements of the water supply device 300, such as pumps, motors, and the like. In this case, the identification data of the water supply device 300 may change before and after the replacement of the electrical component. The electrical unit of the water supply device 300 includes a processor that reads and writes various data such as identification data and backup data, executes commands, controls a motor, and the like. In addition, the electrical unit of the water supply device 300 includes a memory for temporarily storing a program executed by the processor and data used by the processor in order to realize such processing. These processors and memory may be integrated, for example, as a microcontroller.

The electrical unit of the water supply device 300 can further use a communication I / F for connecting to an external device. The communication I / F may be built in the water supply device 300 or may be externally attached to the water supply device 300.

The communication I / F can be any interface capable of communicating with, for example, the communication I / F used by the terminal 200. For example, the communication I / F communicates with the terminal 200 using (near field) wireless communication technology or wired communication technology. The communication I / F transmits identification data and backup data (which may include parameters) of the water supply device 300 (or its electrical component) to the terminal 200, and receives a command from the terminal 200.

The water supply device 300 can also use an auxiliary storage device for accumulating data. The auxiliary storage device may be built in the water supply device 300 or may be externally attached to the water supply device 300.

The auxiliary storage device stores, for example, identification data, parameters, and the like of the water supply device 300. The auxiliary storage device is preferably a non-volatile storage medium. The identification data may be written in, for example, a ROM built in the microcontroller at the time of manufacturing, shipping, and delivering the water supply device 300, or at the time of replacing the water supply device 300 or its electrical component. The writing of these data may be performed by either wired or wireless communication.

Here, the identification data of the water supply device 300 includes, for example, format data corresponding to the product name of the water supply device 300 and / or a product number in which the format data is encoded, and individual identification of the water supply device 300 or its electrical component. It may include a serial number corresponding to the number. From these data, it becomes possible to identify which individual of which product the water supply device 300 is. The product number and the serial number do not necessarily have to be different data elements, and it is possible to design so that both the product and the individual can be identified from one number.

Next, the description of the configuration example of the water supply device 300 will be continued with reference to FIG. The water supply device 300 of FIG. 4 includes a pump 301, a motor 302, and an electrical component 310. The motor 302 is connected to the electrical component 310 via a signal line, and the rotation speed and the like are controlled by the electrical component 310. The pump 301 is connected to the rotating shaft of the motor 302.

In the example of FIG. 4, the pump 301 is a pump for water supply, but when the water supply device 300 is replaced with another pump device, the pump 301 may be replaced with any kind of pump. That is, the pump 301 may be a pump for any purpose such as pumping, drainage, and compression. Further, the pump 301 can handle not only water but also any fluid such as gas. Further, as described above, the water supply device 300 is only an example of the device to which this embodiment is applicable, and the water supply device 300 can be replaced with another device.

The electrical unit 310 includes a control unit 311, a communication unit 312, an identification data storage unit 313, and a parameter storage unit 314.

The control unit 311 controls various functional units inside the motor 302 and the electrical component unit 310, inputs / outputs, and performs various calculations. The control unit 311 may correspond to the above-mentioned processor.

Specifically, the control unit 311 can be used from the communication unit 312 or an input I / F (not shown) when the water supply device 300 is manufactured, shipped, delivered, or when the water supply device 300 or its electrical component 310 is replaced. It receives a request for writing identification data of the water supply device 300 or its electrical component 310, and stores the identification data in the identification data storage unit 313.

Further, the control unit 311 can control the rotation speed of the motor 302 and the like based on, for example, the pressure, the flow rate, and / or the parameters stored in the parameter storage unit 314 detected by a detection device (not shown).

Further, the control unit 311 receives a command for setting a parameter from the communication unit 312, and sets the parameter according to the command. For example, the control unit 311 rewrites the parameter stored in the parameter storage unit 314, writes a new parameter, or deletes the stored parameter.

Further, the control unit 311 reads out the identification data stored in the identification data storage unit 313 and / or the parameters stored in the parameter storage unit 314 and transmits them to the terminal 200 via the communication unit 312, or the terminal. The 200 may be displayed in a readable format. Such an operation may be performed voluntarily, or may be performed triggered by a data acquisition command from the terminal 200. Further, the control unit 311 may create backup data including, for example, date and time data in addition to the read parameters, and send the backup data to the communication unit 312.

The communication unit 312 exchanges various data with the terminal 200. For example, the communication unit 204 may receive the identification data and / or backup data (which may include parameters) acquisition command, parameter setting command, and the like from the terminal 200, and send the received data to the control unit 311. On the other hand, the communication unit 312 may receive identification data and / or backup data from the control unit 311 and transmit this to the terminal 200. The communication unit 312 may correspond to the above-mentioned communication I / F.

The identification data storage unit 313 stores identification data that uniquely identifies the water supply device 300 or its electrical component 310. The identification data is read and written by the control unit 311. However, when the identification data is immutable, the control unit 311 may write the identification data only once. The identification data storage unit 313 may correspond to the above-mentioned memory (however, preferably a non-volatile memory) and / or an auxiliary storage device.

The parameter storage unit 314 stores the parameters set in the water supply device 300. The parameters are read and written by the control unit 311. The parameter storage unit 314 may correspond to the memory and / or auxiliary storage device described above.

Hereinafter, an operation example of the backup system of FIG. 1 will be described with reference to FIGS. 7 to 9.
FIG. 7 illustrates the operation of the system when the backup data is registered. Such an operation can be started, for example, by a worker in charge of the water supply device 300 operating the terminal 200 to back up data such as the parameters after setting / adjusting the parameters.

The terminal 200 issues an identification data and backup data acquisition command and transmits the command to the water supply device 300 (step S401). Step S401 can be omitted when the water supply device 300 voluntarily transmits such data, or when the terminal 200 displays the data in a readable format, or when the worker directly inputs the data.

The water supply device 300 returns the identification data and the backup data to the terminal 200 in response to the command in step S401 (step S402). Note that step S402 can be omitted when the worker directly inputs such data.

The terminal 200 issues a backup request including the identification data and the backup data received in step S402 (step S404). Then, the terminal 200 transmits the issued backup request to the backup server 100 (step S405). As an option, the terminal 200 may temporarily save the issued backup request. As a result, even in an environment where the terminal 200 cannot access the backup server 100, the backup request can be retransmitted later. Further, as described above, the backup request may be directly input to the backup server 100. In this case, steps S401 to S405 and step S409 described later can be omitted.

The backup server 100 searches, for example, the key data associated with the identification data included in the backup request in step S405 from the key data table (DB) described above (step S406). If the key data search fails in step S406, the backup server 100 issues new key data different from any of the registered key data, and the new key data is included in the backup request. It may be registered in association with the identification data (step S407).

The backup server 100 associates the key data searched in step S406 or the new key data registered in step S407 with the backup data included in the backup request in step S405, for example, the backup data table (DB) described above. Register in (step S408). Then, the backup server 100 returns the backup completion notification to the terminal 200 (step S409).

FIG. 8 illustrates the operation of the system during data restoration. Such an operation is performed, for example, when the worker in charge of the water supply device 300 adjusts the parameters on a trial basis, or when the set parameters disappear due to a malfunction of the auxiliary storage device as the parameter storage unit 314, or the like. It can be started by operating the terminal 200 to restore the backed up data of the water supply device 300.

The terminal 200 issues an identification data acquisition command and transmits it to the water supply device 300 (step S411). Step S411 can be omitted when the water supply device 300 voluntarily transmits such data, or when the terminal 200 displays the data in a readable format, or when the worker directly inputs the data.

The water supply device 300 returns the identification data to the terminal 200 in response to the command in step S411 (step S412). Note that step S412 can be omitted when the worker directly inputs such data.

The terminal 200 issues a search request including the identification data received in step S412 (step S413). Then, the terminal 200 transmits the issued search request to the backup server 100 (step S415).

As an option, the terminal 200 may search the local DB previously downloaded from the backup server 100 based on the issued search request (step S414). As a result, data can be restored even in an offline environment, and even when online, data can be restored at a higher speed than when data is exchanged with the backup server 100. If the search in step S414 is successful, step S415 and steps S416 to S418 described later can be omitted.

The backup server 100 searches, for example, the key data associated with the identification data included in the search request in step S415 from the key data table (DB) described above (step S416). Further, the backup server 100 searches the backup data associated with the key data searched in step S416 from, for example, the backup data table (DB) described above (step S417). Then, the backup server 100 returns the searched backup data (including parameters) to the terminal 200 as a search response (step S418).

Based on the search response in step S418, the terminal 200 issues a parameter setting command for setting the parameters included in the search response in the water supply device 300 (step S419). The terminal 200 transmits a parameter setting command to the water supply device 300 (step S420).

The water supply device 300 sets (updates) the parameters according to the parameter setting command in step S420 (step S421). Then, the water supply device 300 returns the parameter setting completion notification to the terminal 200 (step S422).

FIG. 9 illustrates the operation of the system at the time of initial setting (link setting). In such an operation, for example, when a worker in charge of the water supply device 300 replaces / replaces the water supply device 300 or its electrical component 310, the terminal 200 is operated to set a link between the identification data before and after the replacement. Can start with. In the example of FIG. 9, a link is set between the identification data of the water supply device 300-b2 and the identification data of the water supply device 300-b1.

The terminal 200 issues an identification data acquisition command and transmits it to the water supply device 300-b1 and the water supply device 300-b2 (step S431 and step S433). When the water supply device 300-b1 and / or the water supply device 300-b2 voluntarily transmits such data, or when the terminal 200 displays the data in a readable format, or when the worker directly inputs the data. Is optional for step S431 and / or step S433.

The water supply device 300-b1 returns the identification data to the terminal 200 in response to the command in step S431 (step S432). Note that step S432 can be omitted when the worker directly inputs such data.

The water supply device 300-b2 returns the identification data to the terminal 200 in response to the command in step S433 (step S434). Note that step S434 can be omitted when the worker directly inputs such data.

The terminal 200 issues an initial setting request including the identification data received in steps S432 and S434 as the link source identification data and the link destination identification data, respectively (step S436). Then, the terminal 200 transmits the issued initial setting request to the backup server 100 (step S437). As an option, the terminal 200 may temporarily save the issued initial setting request. As a result, even in an environment where the terminal 200 cannot access the backup server 100, the initial setting request can be retransmitted later. Further, as described above, the initial setting request may be directly input to the backup server 100. In this case, steps S431 to S434, and steps S439 or S440 to S445 described later can be omitted.

The backup server 100 searches the key data associated with the link source identification data included in the initial setting request in step S437 from, for example, the above-mentioned key data table (DB), and uses this key data as the link included in the initial setting request. It is registered in the key data table in association with the destination identification data (step S438).

As an option, after step S438, the backup server 100 may send an initial setting completion notification as an initial setting response to the terminal 200 (step S439). In this case, steps S440 to S445 described later can be omitted. Alternatively, as will be described later using steps S440 to S445, the system does not wait for the search request including the identification data of the water supply device 300-b2, but in the water supply device 300-b2, the water supply device 300-b1 The backup data may be restored automatically.

In step S440, the backup server 100 searches the backup data table (DB) described above for backup data associated with the key data registered in step S438. Then, the backup server 100 returns the searched backup data (including parameters) to the terminal 200 as an initial setting response (step S441).

Based on the initial setting response in step S441, the terminal 200 issues a parameter setting command for setting the parameters included in the initial setting response in the water supply device 300 (step S442). The terminal 200 transmits a parameter setting command to the water supply device 300 (step S443).

The water supply device 300 sets the parameters according to the parameter setting command in step S443 (step S444). Then, the water supply device 300 returns the parameter setting completion notification to the terminal 200 (step S445).

As described above, the backup system according to the first embodiment does not directly associate the backup data of the device with the identification data of the device, but indirectly associates it with the key data. Then, this backup system associates the identification data of a plurality of different devices to be linked with the same key data. Therefore, according to this backup system, for example, the identification data of the device before replacement and the identification data of the device after replacement can be associated with the same key data, so that the identification data of the device after replacement can be used for replacement. It is possible to restore the backup data of the previous device. That is, the backup data of the device can be automatically taken over and managed even after the replacement of the device or its parts.

(Second Embodiment)
The backup system according to the first embodiment described above makes it possible to restore the backup data of the device before replacement by using the key data, for example, using the identification data of the device after replacement. On the other hand, the backup system according to the second embodiment can realize the same effect without using the key data. The backup system according to the present embodiment includes a backup server 500 instead of the backup server 100 in the backup system according to the first embodiment.

The backup server 500 has the same or similar hardware configuration as the backup server 100, but differs in at least a part of its functional configuration and operation. The description of the configuration example of the backup server 500 will be continued with reference to FIG. The backup server 500 of FIG. 10 includes an initial setting request acquisition unit 501, a backup request acquisition unit 502, a search request acquisition unit 503, a data registration unit 504, a backup data storage unit 506, a data search unit 507, and a request. A response unit 508 and a data deletion unit 509 are included. Of these, the initial setting request acquisition unit 501, the backup request acquisition unit 502, the search request acquisition unit 503, and the request response unit 508 may be the same or similar to the elements having the same name in FIG. 2, respectively.

The data registration unit 504 may correspond to the above-mentioned processor. The data registration unit 504 registers data (entry) in the database constructed in the backup data storage unit 506 in response to various requests such as an initial setting request and a backup request. The data registration unit 504 differs from the data registration unit 104 of FIG. 2 in that at least the following description is given.

The data registration unit 504 receives an initial setting request from the initial setting request acquisition unit 501. The data registration unit 504 searches the database built in the backup data storage unit 506 for the backup data associated with the link source identification data included in the initial setting request. Then, the data registration unit 504 associates the link destination identification data included in the initial setting request with the backup data and registers it in the database (that is, registers it in the backup data storage unit 506).

Specifically, the backup data storage unit 506 can store a backup data table (DB) including entries e31, e32, e33, ..., As illustrated in FIG. Here, it is assumed that the initial setting request includes id_b1 as the link source identification data and id_b2 as the link destination identification data. In this case, the data registration unit 504 searches the backup data table for backup_B, which is backup data associated with id_b1 as the link source identification data. Then, the data registration unit 504 duplicates this backup data, associates id_b2 as the link destination identification data with this, and registers it as a new entry in the above table. This makes it possible to search and restore the backup data (backup_B) of the water supply device 300 identified by id_b1 as the link source identification data based on id_b2 as the link destination identification data.

If the link source identification data and the corresponding backup data (entry e32 in the example of FIG. 11) are unnecessary after the initial setting (link setting) is completed, this entry is backed up by the data deletion unit 509 described later. It may be deleted from the storage unit 506. As a result, it is possible to prevent the capacity of the backup data storage unit 506 from being compressed due to duplicate registration of backup data. For example, the data registration unit 504 may notify the data deletion unit 509 of the entry to be deleted after the initial setting is completed.

The backup data storage unit 506 stores the identification data in association with the backup data. For example, the backup data storage unit 506 may store the identification data and the backup data in a table format. This table can also be called a database. The backup data storage unit 506 may correspond to the memory and / or auxiliary storage device described above.

The backup data storage unit 506 may write identification data and backup data by the data registration unit 504. Further, the identification data and the backup data stored in the backup data storage unit 506 can be deleted by the data deletion unit 509. Further, the data stored in the backup data storage unit 506 can be read out by the data registration unit 504 and the data search unit 507 (including the search).

The data search unit 507 may correspond to the above-mentioned processor. The data search unit 507 searches the backup data associated with the identification data from the database constructed in the backup data storage unit 506 in response to various requests such as a search request. The data search unit 507 differs from the data search unit 107 of FIG. 2 in that at least the following description is given.

The data search unit 507 receives a search request from the search request acquisition unit 503. The data search unit 507 searches the backup data associated with the identification data included in the search request from the database constructed in the backup data storage unit 506.

The data deletion unit 509 may correspond to the above-mentioned processor. When the data deletion unit 509 is notified of the entry to be deleted (identification data and the corresponding backup data) from the data registration unit 504, the data deletion unit 509 deletes this entry from the backup data storage unit 506. The data deletion unit 509 may issue an initial setting completion notification and send it to the request response unit 508 instead of the data registration unit 504.

As described above, the backup system according to the second embodiment has a database that associates the device identification data with the backup data of the device. Then, when the backup server acquires the initial setting request including the identification data of a plurality of different devices to be linked, the backup server associates the link destination identification data with the backup data associated with the link source identification data in this database. And register it in the database. Therefore, according to this backup system, for example, the backup data associated with the identification data of the device before replacement is also associated with the identification data of the device after replacement, so that the device is exchanged using the identification data of the device after replacement. It is possible to restore the backup data of the previous device. That is, the backup data of the device can be automatically taken over and managed even after the replacement of the device or its parts.

The above embodiments are merely specific examples to aid in understanding the concepts of the invention and are not intended to limit the scope of the invention. In the embodiment, various components can be added, deleted or converted without departing from the gist of the present invention.

In the above-described embodiment, some functional parts have been described, but these are only examples of implementation of each functional part. For example, it is possible that a plurality of functional parts described as being mounted on one device may be mounted on a plurality of separate devices, and conversely, it is described as being mounted on a plurality of separate devices. It is also possible that the functional unit is mounted on one device.

The various functional parts described in each of the above embodiments may be realized by using a circuit. The circuit may be a dedicated circuit that realizes a specific function, or may be a general-purpose circuit such as a processor.

At least a part of the processing of each of the above embodiments can be realized by using, for example, a processor mounted on a general-purpose computer as basic hardware. The program that realizes the above processing may be provided by storing it in a computer-readable recording medium. The program is stored on the recording medium as a file in an installable format or a file in an executable format. Examples of the recording medium include magnetic disks, optical disks (CD-ROM, CD-R, DVD, etc.), magneto-optical disks (MO, etc.), semiconductor memories, and the like. The recording medium may be any medium as long as it can store the program and can be read by a computer. Further, the program that realizes the above processing may be stored on a computer (server) connected to a network such as the Internet and downloaded to the computer (client) via the network.
