JP5937146B2 - Lost and found search system and control method - Google Patents

Description

  The present invention relates to a lost article search system and a control method capable of quickly and safely searching for lost articles such as lost items and lost items.

Searching for lost items is performed by actually searching for places where it seems that the lost items have been found, or by inquiring to nearby police stations or stations where the lost items are considered.
However, the method of actually searching the place visited is effective when the range of action is limited (for example, when going back and forth to a nearby bookstore), The range of possible locations is widened, requiring a lot of time and effort. Also, when making an inquiry to a police box or a station, the number of inquiries increases as the range of action increases, which is very laborious.

  In consideration of such circumstances, a system for facilitating the search for lost items has been proposed (see, for example, Patent Document 1). In this patent document 1, a mobile phone is used as a parent device, and a device that is attached to the belongings is used as a child device so that the parent device issues an alarm when communication between the parent device and the child device becomes impossible. Thus, a cellular phone with a left-behind prevention function that prevents left-behind is disclosed.

  In the following description, when one of the users who subscribe to the service provided by the lost article search system 1000 loses an item to which the beacon terminal 100 is attached, the other users who subscribe to this service It is assumed that a lost item (hereinafter referred to as “user lost item”) is searched with cooperation (or using an access point). Hereinafter, a user who requests a search is referred to as a user, a mobile device owned by the user is referred to as a mobile device 200A, a user who receives a search request is a cooperative user, and a mobile device owned by the cooperative user is a mobile device 200B. Call.

FIG. 2 is a functional block diagram of beacon terminal 100.
The beacon terminal 100 is a terminal having a short-range wireless communication function represented by Bluetooth (registered trademark), a control unit 110 including a CPU, a memory 120, and other devices having a Bluetooth communication function. And a Bluetooth communication unit 130 for performing P2P communication. The beacon terminal 100 may have various shapes such as a coin-sized chip, a sticker, and a tag. However, since it is assumed that the beacon terminal 100 is attached to various items, it is desirable that the beacon terminal 100 has a shape that is small, lightweight, and easy to attach. Bluetooth communication is assumed to be compliant with various standards. In the memory 120, UUID (Universally Unique Identifier) for uniquely identifying the service, major information for identifying the beacon terminal 100, and minor information (terminal identification information) are registered as information for identifying the transmission source. ing. Although details will be described later, the UUID stored in the memory 130 is sequentially updated at regular intervals when the beacon terminal 100 is in a normal state (that is, a state in which it is not lost).

FIG. 3 is a functional block diagram of mobile device 200.
The mobile device 200 is, for example, a mobile phone typified by a smartphone, and includes a control unit 210 configured by a CPU, a display unit 220 including a liquid crystal panel, an operation unit 230 including various keys, and the like. A Bluetooth communication unit 240 and a memory 250 are provided. Of course, the mobile device 200 is equipped with hardware and software for realizing basic functions (such as voice communication and data communication functions) as a mobile phone. In the memory 250, an application (hereinafter referred to as “search application”) AP1 necessary for using the system 1000 is recorded. Each user who owns the mobile device 200 can use the system 1000 by downloading the search application AP1 from a predetermined server.

FIG. 4 is a functional block diagram of the management server.
The management server 300 is composed of a server computer and the like, manages the search for user lost items using the system 1000, performs registration processing for users using the system 1000, periodic UUID payout processing described later, and the like. Do. The management server 300 includes a database 310 that manages user registration information and the like, and a UUID generation unit 320 that periodically pays out random UUIDs. Hereinafter, the basic operation of the lost article search system 1000 will be described with reference to the drawings.

(2) Operation 2-1. User Registration Processing FIGS. 5 to 7 are sequence diagrams showing a series of flow from user registration processing to UUID update processing and search processing.
As shown in FIGS. 5-7, this user performs a pairing process between the mobile device A and the beacon terminal 100 (step C1). In the pairing process, the mobile device A receives, from the beacon terminal 100, unique terminal identification information including major information and minor information together with a UUID that uniquely identifies this service, and stores these in the memory 250, The beacon terminal 100 receives the unique mobile device identification information of the mobile device A and stores it in the memory 130. By performing this pairing process, the mobile device A and the beacon terminal 100 can authenticate each other.

  When the pairing process ends, the user uses the mobile device A to register the beacon terminal 100 with the management server 300 (that is, user registration). The mobile device A cooperates with the installed search application AP1 and first accesses the management server 300. In response to the access request from the mobile device A, the management server 300 authenticates whether the user can use the system (that is, the mobile device A) by using the telephone number of the mobile device A, for example. If the authentication is successful, the management server 300 requests the mobile device A for major information and minor information (terminal identification information) of the beacon terminal 100 as information for identifying the beacon terminal 100 paired with the mobile device A. To do. In response to this request, the mobile device A reads the major information and minor information of the beacon terminal 100 from the memory 250 and transmits them to the management server 300 (step C2). The management server 300 associates mobile device identification information (for example, a telephone number) identifying the mobile device A with the major information and minor information of the beacon terminal 100 and registers them in the database 310. Then, the management server 300 returns to the mobile device A that the user registration has been normally completed, and ends the user registration process. If the authentication fails or the user registration cannot be completed normally, the management server 300 sends a message to that effect to the mobile device A and ends the process.

2-2. UUID Update Process When the user registration process is completed, the management server (first notification means) 300 notifies the mobile device A of the UUID for one week (step C3). Here, the UUID for one week to be notified is randomly generated by the UUID generation unit 320 of the management server 300. In the present embodiment, the UUID (service identifier) of the beacon terminal 100 is updated at a rate of once a day (that is, every 24 hours) (step C4). This update interval may be specified when the management server 300 notifies the UUID for one week, for example. Of course, the update interval (predetermined frequency) can be arbitrarily set / changed according to the service specifications. For example, the update interval (predetermined frequency) may be updated at intervals of 12 hours or once every two days. When the mobile device A receives a UUID for one week from the management server 300, the mobile device A holds it in the memory 250. The mobile device A determines whether or not the update timing has arrived using a mounted timer (not shown) or the like. When determining that the update timing has arrived, the mobile device (update means) A updates the UUID registered in the beacon terminal 100. For example, as shown in FIG. 8, when the UUID of the beacon terminal 100 is updated by the mobile device A, the UUID of the beacon terminal 100 is switched from “EEEE...” To “FFFF. In the present embodiment, the UUID is updated for all beacon terminals 100 registered as a user. Further, the UUID to be updated is common to all beacon terminals 100. For example, the UUID that is updated at a certain timing is “GGGG...” Common to all beacon terminals 100.

2-3. Search process <Phase 1>
Phase 1 assumes a case where a user who notices the loss of an item requests a limited collaborative user to search for a user lost item, and the processing flow corresponds to FIG.
The mobile device (determination means) A determines whether or not the item has been lost based on any of the following criteria.
(1) The UUID of the beacon terminal 100 is not updated (first determination criterion).
(2) The asynchronous state between the beacon terminal 100 and the mobile device A continues for a predetermined time or longer (second determination criterion).

  Here, the second determination criterion will be described in detail. A beacon interval (for example, 100 ms) is set in the beacon terminal 100, and a synchronization control signal (beacon signal) is transmitted at the beacon interval. The mobile device A receives the beacon signal transmitted from the beacon terminal 100, and thereby determines that the mobile device A is in synchronization with the beacon terminal 100. On the other hand, when the beacon signal transmitted from the beacon terminal 100 is not confirmed by the mobile device A for a predetermined time (for example, 3 hours) or longer, the mobile device A is synchronized with the beacon terminal 100. It is determined that there is no (that is, asynchronous state). Here, the predetermined time (that is, the determination time of the asynchronous state) described above may be arbitrarily set / changed by the user. For example, depending on the user, it is assumed that the mobile device A and an item (for example, a house key) are not always carried together, but only the mobile device A is taken out for 2 to 3 hours. Etc.) In such a case, if the user can arbitrarily set the determination time for the asynchronous state, erroneous determination can be prevented in advance. In addition, before the mobile device A detects the loss of the beacon terminal 100, the user may naturally notice the loss of the beacon terminal 100.

  When the mobile device A determines that the beacon terminal 100 has been lost based on, for example, either the first or second determination criteria described above, the mobile device (notification means) A has lost the beacon terminal 100 to this user. In order to notify this, a notification message, an alarm, or the like is output using a display panel or a speaker (step C5). Further, the mobile device A cooperates with the search application AP1 to measure the position when the loss of the beacon terminal 100 is detected, acquire the position information and the time information, and store this in the memory 250 as the loss detection information. Register (step C6). Then, the mobile device (notification means, transmission means) A sends the UUID of the beacon terminal 100 that uniquely identifies this service, major information for identifying the beacon terminal 100, and minor information to the management server 300 together with the loss detection information. Transmit (step C7).

  On the other hand, this user who knows the loss of the beacon terminal 100 first operates the operation unit (accepting means) 230 of the mobile device A, so that the registered friend (cooperating user who subscribes to this service) is operated. The user is requested to search for a lost user (that is, the beacon terminal 100) with respect to a limited cooperative user (step C8). As a method of requesting a search by designating a cooperating user, for example, a friend registered in the phone book of the mobile device A (information specifying a friend by specifying a friend (for example, a telephone number)) Is notified to the management server 300. Of course, it is possible to appropriately set / change how to specify the cooperating user according to the service design, etc. Further, the range of cooperating users to be specified ( For example, some friends, colleagues, family members, etc.) may be arbitrarily set, and all users who subscribe to this service may be set as targets of cooperating users.

  When the management server (second notification means) 300 receives the search request for the beacon terminal 100 from the user, the management server (second notification means) 300 refers to the database 310 and specifies the cooperating user (in this case, a friend) designated by the user, The UUID, major information, and minor information (hereinafter referred to as “search key information”) of the beacon terminal 100 to be searched are notified to the mobile devices B of all the cooperating users (step C9). For convenience of explanation, only one mobile device B is shown in FIG. Each mobile device B of the cooperating user starts searching for the beacon terminal 100 based on the search key information of the beacon terminal 100 that receives the notification from the management server 300. On the other hand, the lost beacon terminal 100 transmits a synchronization control signal (beacon signal) at the set beacon interval, as before the loss (step C10). In this beacon signal, UUID, major information, and minor information for identifying the beacon terminal 100 are set.

  Thereafter, when the mobile device B of any of the cooperating users detects (discovers) the beacon terminal 100 that has requested the search (step C11), the position measurement is performed at the time of detection, and the position information and time information are acquired. . Specifically, the mobile device B determines that it has detected the beacon terminal 100 that requested the search by receiving the UUID, the major information, and the minor information that match the search key information. The mobile station B that has detected the beacon terminal 100 transmits the UUID, major information, and minor information of the detected beacon terminal 100 together with the acquired position information and time information to the management server 300 (step C12), thereby requesting a search request. The management server 300 is notified of the detected beacon terminal 100. The mobile device B that has detected the beacon terminal 100 may transmit the acquired position information and time information to the management server 300.

  When the management server (reception means, third notification means) 300 receives a notification from the mobile device B that the beacon terminal 100 has been detected, the beacon terminal 100 sends it to the mobile device A of the user who requested the search. While notifying that it has been discovered, the location information and time information received from the mobile device B at the time when the beacon terminal 100 is discovered (detected) are transmitted (step C13).

  Based on the notification from the management server 300, the mobile device A displays a message indicating that the beacon terminal 100 has been found on the display panel, and further outputs a voice so that the beacon terminal 100 is discovered by the user. Notify that. Further, based on the position information and time information received from the management server 300, the mobile device A displays the position where the beacon terminal 100 is found on a map and displays the discovery time as a message.

  While referring to the display message of the mobile device A, the user goes to a place where the beacon terminal 100 is found (for example, a cafe in front of a station where a meeting with a plurality of friends was held). When the beacon terminal 100 is successfully discovered by the user, a synchronization process is started between the mobile device A and the beacon terminal 100 (step C14). At this time, for example, when it is detected that the UUID transmitted from the beacon terminal 100 is an old UUID that has not been updated, the mobile device A reads the correct UUID that should be updated at that time from the memory 250, and the beacon terminal The UUID of 100 is updated (step C15). When the mobile device A updates the UUID of the beacon terminal 100 and confirms that the synchronization with the beacon terminal 100 is established again, the mobile device A re-establishes a search with the beacon terminal 100 that has made a search request to the management server 300. The fact that synchronization has been achieved is notified (step C16). If the time from when the beacon terminal 100 is lost until the beacon terminal 100 returns to the user's hand is short, the UUID is not updated (for example, after the beacon terminal 100 is lost, Note that there are also cases (such as returning to hand in ~ 3 hours).

  When the management server (fourth notification means) 300 receives a notification from the mobile device A that the resynchronization with the beacon terminal 100 has been established, the management server (fourth notification means) 300 searches the mobile devices B of all the cooperating users who requested the search in this case The point where the target beacon terminal 100 was found successfully and the cancellation of the search request are notified (step C17), and the process is terminated. If the beacon terminal 100 is left in a place close to the user who requested the search (for example, in a place where the user does not normally enter), even if the search request is made, It can happen that it is not found at all. Considering such a situation, for example, an investigation deadline (for example, one week) may be set in advance, and if no clue is obtained within this deadline, the search may be aborted. Note that the expiry time limit for investigation may be arbitrarily set / changed by the user, or a fixed value may be set by default.

  As explained above, according to the search process of Phase 1, by searching for a collaborative user close to this user (or close to this user), the lost item can be found quickly without making the search large. It becomes possible to do.

<Phase 2>
Phase 2 assumes that all users who subscribe to this service search the stray beacon terminal 100, and the processing flow corresponds to FIG. Since the user registration process and the UUID update process have already been described above, the corresponding process flow is denoted by the same reference numeral, and detailed description thereof is omitted. Here, the stray beacon terminal 100 is a beacon terminal 100 lost by any user who subscribes to the service, and the beacon terminal 100 transmitting an old UUID (that is, a UUID that has not been updated normally). Say. For convenience of explanation, it is assumed below that the beacon terminal 100 lost by the user is detected as the stray beacon terminal 100.

  When the mobile device A refers to a timer or the like and determines that the update timing of the UUID of the beacon terminal 100 has arrived, the mobile device A attempts to update the UUID. Here, when the beacon terminal 100 is lost, the mobile device A cannot update the UUID of the beacon terminal 100. Since the mobile device (determination means) A cannot update the UUID (first determination criterion) and determines that the beacon terminal 100 has been lost (step Ca5), it is confirmed that the beacon terminal 100 has been lost to this user. In order to notify, a notification message, an alarm, etc. are output using a display panel or a speaker (step Ca6). On the other hand, the lost beacon terminal 100 is originally not updated at the timing when it should be updated, so the old UUID is retained and the field becomes stray (step Ca7: generation of the field beacon terminal 100).

  The stray beacon terminal 100 (that is, the lost beacon terminal 100) transmits the synchronization control signal (beacon signal) at the set beacon interval as before the stray (that is, before the loss) (step Ca8). ). In this beacon signal, UUID for identifying this service, major information for identifying beacon terminal 100, and minor information are set, but UUID could not be updated normally at the previous update timing. Therefore, the old UUID is transmitted from the stray beacon terminal 100.

  On the other hand, the mobile devices 200 of all users who have subscribed to this service, that is, the mobile device A and the mobile device B, have been updated in the past in addition to the UUID for a certain period (for example, one week) to be updated. A UUID for a certain period (for example, three weeks) is recorded in the memory 250. As described above, since the UUID is a unique value for identifying this service, an updated UUID is transmitted from a normal beacon terminal 100 (that is, a beacon terminal 100 that has not been strayed). Become. Here, since the update timing is substantially the same in all beacon terminals 100 that are the targets of this service, UUIDs transmitted from all normal beacon terminals 100 are common.

  On the other hand, the stray beacon terminal 100 continues to transmit the old UUID. When the mobile devices 200 of all users receive a beacon signal from the beacon terminal 100, they detect whether the beacon terminal 100 is a normal beacon terminal 100 by detecting the UUID set in the beacon signal, or a stray beacon. It is possible to determine whether the terminal 100 is used.

  Here, as shown in FIG. 9, when the mobile device (detection means) B of any cooperating user detects the stray beacon terminal 100 by receiving the old UUID (step Ca9), the search for the mobile device B is performed. The application AP1 performs position measurement in the background and acquires position information and time information. The mobile device (transmission means) B that has detected the stray beacon terminal 100 transmits the old UUID, major information, and minor information of the detected stray beacon terminal 100 together with the acquired position information and time information to the management server 300 ( Step Ca10), the detection of the stray beacon terminal 100 is notified to the management server 300. When the management server 300 receives these pieces of information, the management server 300 refers to the database 310 to identify the beacon terminal 100 corresponding to the stray beacon terminal 100. Then, the position information and time information of the beacon terminal 100 are registered in the database 310. In practice, a report indicating that the same stray beacon terminal 100 is detected from a plurality of mobile devices B may be received. In such a case, the position information and time information may be registered in the database 310 in time series.

  On the other hand, the user makes an inquiry to the management server 300 using the mobile device A for the lost beacon terminal 100 (that is, the stray beacon terminal 100) (step Ca11). More specifically, since the major information and minor information of the lost beacon terminal 100 are registered in the memory 250 of the mobile device A, the lost beacon terminal 100 is inquired using the major information and minor information. Do.

  The management server 300 requests a request for the telephone number of the mobile device A and user registration information in order to determine the validity of the inquiry (step Ca12). The management server (authentication unit) 300 performs authentication by comparing the user registration information input by the user with the user registration information registered in the database 310 (step Ca13). If the authentication is successful, the management server (fifth notification means) 300 reads the location information and time information of the stray beacon terminal 100 received from the mobile device B from the database 310, and the location of the stray beacon terminal 100 with respect to the mobile device A. Information and time information are notified (step Ca14). Note that the authentication method can be set or changed as appropriate according to the service design or the like. For example, in order to improve security, the user may authenticate by calling the management server 300 directly and checking the user information by the operator. In such a case, after successful authentication, the operator may notify the user of the location information of the stray beacon terminal 100 by telephone, or may be notified using e-mail or the like.

  Based on the location information and time information of the stray beacon terminal 100 (that is, the lost beacon terminal 100) received from the management server 300, the mobile device A displays a map of the location where the stray beacon terminal 100 is found and the discovery time Is displayed as a message.

  While referring to the display message of the mobile device A, the user goes to a place where the beacon terminal 100 is found (for example, a parking lot in a shopping center). When the beacon terminal 100 is successfully discovered by the user, a synchronization process is started between the mobile device A and the beacon terminal 100 (step Ca15). At this time, for example, when it is detected that the UUID transmitted from the beacon terminal 100 is an old UUID that has not been updated, the mobile device A reads the correct UUID that should be updated at that time from the memory 250, and the beacon terminal The UUID of 100 is updated (step Ca16). When the mobile station A confirms that the beacon terminal 100 is synchronized again by updating the UUID of the beacon terminal 100, the mobile station A notifies the management server 300 that resynchronization with the beacon terminal 100 has been established, The updated UUID, major information, and minor information of the beacon terminal 100 are notified (step Ca17). Upon receiving these notifications, the management server 300 deletes the position information and time information of the beacon terminal 100 registered in the database 310 (step Ca18) and ends the process.

  As described above, according to the search process in phase 2, the search for the stray beacon terminal 100 is performed for all users who subscribe to this service, so it is possible to find lost items more quickly and reliably. It becomes. Further, in phase 2, since the stray beacon terminal 100 (that is, the beacon terminal 100 whose UUID has not been updated normally) is searched indiscriminately, it is not necessary to terminate the search for the lost beacon terminal 100. Furthermore, if the search process of phase 1 is combined with the search process of phase 2, it becomes possible to find a lost item more reliably.

<Phase 3>
Phase 3 assumes a case in which the stray beacon terminal 100 is searched using an access point (WiFi Access Point) 400 managed by a communication carrier or the like, and the processing flow corresponds to FIG. Since the user registration process and the UUID update process and the process generated by the stray beacon terminal 100 have already been described above, the corresponding processing flow is denoted by the same reference numeral, and detailed description thereof is omitted. In addition, for convenience of explanation, it is assumed below that the beacon terminal 100 lost by the user is detected as the stray beacon terminal 100.

  As in the phase 2, the stray beacon terminal 100 (that is, the lost beacon terminal 100) transmits the synchronization control signal (beacon signal) at the set beacon interval as before the stray (that is, before the loss). (Step Ca8). In this beacon signal, UUID for identifying this service, major information for identifying beacon terminal 100, and minor information are set, but UUID could not be updated normally at the previous update timing. Therefore, the old UUID is transmitted from the stray beacon terminal 100.

  On the other hand, the access point 400 installed in various places such as a shopping mall or a station premises has a UUID for a certain period (for example, one week) to be renewed in the same manner as the mobile station B in Phase 2. The UUID for a certain period (for example, for three weeks) updated in the past is recorded in a memory (not shown). Specifically, UUID is notified from the management server 300 to each access point 400 at a predetermined update timing (step Cb3).

  Here, as shown in FIG. 10, when any access point (detection means) 400 detects the stray beacon terminal 100 by receiving the old UUID (step Cb9), the access point 400 sets a timer or the like. While referring to the time information, the MAC address assigned to the access point 400 is read out as position information. The access point (transmission means) 400 that detected the stray beacon terminal 100 transmits the old UUID, major information, and minor information of the detected stray beacon terminal 100 to the management server 300 together with the acquired time information and position information (MAC address). By doing so (step Cb10), the management server 300 is notified of the detection of the stray beacon terminal 100.

  When the management server 300 receives these pieces of information, the management server 300 refers to the database 310 to identify the beacon terminal 100 corresponding to the stray beacon terminal 100. Further, the management server (inquiry means) 300 makes an inquiry to the access point management server 500 using the MAC address received as the position information as a key (step Cb11). In the access point management server 500, the MAC address and the installed address are registered in association with each other for all the access points 400. In response to an inquiry from the management server 300, the access point management server (notification means) 500 reads the address (for example, “Shinjuku-ku...”) Where the access point corresponding to the MAC address is installed ( Return to the management server 300 (see FIG. 10) (step Cb12).

  Thereafter, as in the phase 2, the user makes an inquiry to the management server 300 using the mobile device A for the lost beacon terminal 100 (that is, the stray beacon terminal 100) (step Ca11). The management server 300 requests a request for the telephone number of the mobile device A and user registration information in order to determine the validity of the inquiry (step Ca12). The management server (authentication unit) 300 performs authentication by comparing the user registration information input by the user with the user registration information registered in the database 310 (step Ca13). If the authentication is successful, the management server (sixth notification means) 300 reads the location information and time information of the stray beacon terminal 100 received from the mobile device B from the database 310, and the location of the stray beacon terminal 100 with respect to the mobile device A. Information and time information are notified (step Ca14). Since the subsequent operation is the same as in phase 2, the same reference numerals are assigned to the corresponding processes, and further description is omitted.

  As described above, according to the search processing in phase 3, the search for the stray beacon terminal 100 is performed using access points installed in various places such as shopping malls and station premises, so that the speed is increased. And it will be possible to detect lost items without fail. Further, in Phase 3, in order to search for the stray beacon terminal 100 (that is, the beacon terminal 100 in which the UUID has not been updated normally) indiscriminately, as in Phase 2, the search for the lost beacon terminal 100 is terminated. It is unnecessary. Furthermore, if the search process of phase 3 is combined with the search process of phase 1 or phase 2, it becomes possible to discover a lost item more reliably.

B. Others In this embodiment, Bluetooth communication is exemplified as a representative of short-range wireless communication, but the present invention can also be applied to various types of communication (for example, optical wireless data communication using infrared rays) realized by other communication standards.

  Moreover, in this embodiment, although the mobile phone represented by the smart phone was illustrated as an example of the mobile device 200, it is not the meaning limited to this. The present invention is also applicable to a personal computer having a Bluetooth communication function, a personal digital assistant (PDA), a wearable terminal, and the like.
