The information extracting unit to be stored and the user database are referred to, the address of the second user terminal corresponding to the extracted identification number is searched, and the searched address is the safety of the safety confirmation database. A safety unconfirmed terminal determination unit that determines whether it is stored in the confirmed terminal address, and the safety confirmation if the address of the second user terminal is not stored in the safety confirmed terminal address of the safety confirmation database. Referring to the database, a search request for the second user terminal is transmitted to the address of the safety confirmed terminal that stores the identification number of the second user terminal in the identification number of the peripheral terminal And a transmitting unit.

  According to the present invention, it is possible to identify a terminal whose safety has been confirmed by a user who is most likely to be able to confirm the safety of a user who has not yet transmitted safety information. Then, by asking the identified terminal for which the safety has been confirmed to search for the user of the unconfirmed safety terminal, it is easy to grasp the state of the user of the unconfirmed safety terminal.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a conceptual diagram of an embodiment of the present invention. The safety confirmation device 1, user terminals 21, 22, 23, 24 (hereinafter referred to as user terminal 2 when referring to all user terminals) and the information providing device 3 are connected via a network 4.

  When a disaster occurs, the safety confirmation device 1 performs safety confirmation on a user terminal 2 registered in advance. The user terminal 2 is a terminal carried by each of a plurality of users. For example, the user terminal 2 is portable such as a mobile phone, PDA (Personal Digital Assistant), PHS (Personal Handy-phone System), and has a wireless communication function. It is a computer.

  The user terminal 2 includes two wireless communication means. For example, a public wireless communication means is provided as the first wireless communication means, and a short-range wireless communication means such as Bluetooth, Zigbee, or UWB (Ultra Wide Band) is provided as the second wireless communication means. In FIG. 1, four user terminals 21 to 24 are exemplified, but the number is not limited to this number.

  The information providing device 3 is a device that provides information including the date and time of occurrence, the scale of disaster, and the region where the disaster has occurred as a disaster occurrence information, and is a computer that provides a disaster information provision service used by the Meteorological Agency, local governments, private companies, etc. Etc.

  The network 4 may be any communication network as long as computers connected to the Internet, a mobile phone network, a telephone network, and the like can communicate with each other. However, it is desirable that communication between the safety confirmation device 1 and the user terminal 2 is performed via a wireless communication network.

  The safety information 51 and 52 schematically represents data transmitted from the user terminal 2 to the safety confirmation device 1 via the public line network, and indicates the safety of the user carrying the user terminal 2. Contents to be notified are included.

  The search request 9 schematically represents data requesting a safety-confirmed terminal to search for a safety-unconfirmed terminal, and is transmitted from the safety confirmation device 1.

  The short-range wireless communication means communicable ranges 81 and 82 schematically show the ranges in which the short-range wireless communication means included in the user terminal device 2 can communicate. The communicable range of the short-range wireless communication means of the user terminal A21 is 81, and the communicable range of the short-range wireless communication means of the user terminal C23 is 82. For example, if the short-range wireless communication means is Bluetooth Class 2, the short-range wireless communication means communicable range 81, 82 is within a radius of about 10 meters. The short-range wireless communication means communicable ranges 81 and 82 are determined by the type of the short-range wireless communication means and the surrounding environment.

  When the safety confirmation device 1 receives the disaster occurrence information from the information providing device 3, it transmits a response request for requesting a safety information transmission operation to the plurality of user terminal devices 2. Then, the user terminal device 2 uses the short-range wireless communication means to identify the identification numbers of other user terminals existing in the short-range wireless communication means communicable range 8 which is the communicable range of its own short-range wireless communication means. Get. The identification number is information for uniquely identifying the short-range wireless communication means included in each user terminal 2. For example, the address of the Bluetooth device mounted on the user terminal device 2 is used.

  Then, the safety information 5 including the acquired identification number of the peripheral terminal and its own terminal address is transmitted to the safety confirmation device 1. The terminal address is an address of public wireless communication means.

  When the user terminal B22, the user terminal C23, and the user terminal D24 exist in the short-range wireless communication possible range 81 of the user terminal A21, the user terminal A21 is the user terminal B22, the user terminal C23, The identification number of the user terminal D24 can be acquired via the short-range wireless communication network. And the safety information 51 containing the acquired identification number is transmitted to the safety confirmation apparatus 1. Similarly, the user terminal C23 obtains an identification number from the user terminal A21 in the short-range wireless communication means communicable range 82 via the short-range wireless communication network, and the safety information 52 including the acquired identification number. Is transmitted to the safety confirmation device 1.

  The safety confirmation device 1 receives the safety information 51 and 52 from the user terminal A21 and the user terminal C23. Then, it is determined whether or not the safety of the user terminal 2 corresponding to the identification number included in the safety information 51/52 has been confirmed. If there is a safety unconfirmed terminal that has not been confirmed for safety, a search request 9 for requesting a search for a user of the safety unconfirmed terminal is transmitted to a safety confirmed terminal that recognizes the safety unconfirmed terminal in the vicinity. Specific processing will be described later.

  The search request 9 is data of content for requesting search cooperation of a safety unconfirmed terminal existing in the vicinity, and may further include information on a user carrying the safety unconfirmed terminal to be searched.

  For example, the safety confirmation device 1 determines whether the user terminal associated with the identification number included in the safety information 51 received from the user terminal A21 is an unconfirmed safety terminal that has not transmitted safety information. Although details will be described later, since the user terminal B22 and the user terminal D24 are determined to be safety unconfirmed terminals and the user terminal C23 has already transmitted the safety information 52, it is determined to be a safety confirmed terminal. . Then, the safety confirmation device 1 transmits a search request 9 for the user terminal B22 and the user terminal D24 whose safety has not been confirmed to the user terminal device A21.

  At this time, the search request 9 can be transmitted by specifying the safety-confirmed terminal A21 that exists in the vicinity of the safety-unconfirmed terminals B22 and D24 to be searched and that can be searched most efficiently. The safety-confirmed terminal A thus identified searches the safety-unconfirmed terminals B22 and D24, so that the state of the user of the safety-unconfirmed terminal that did not transmit the safety information due to the above-described factors can be easily grasped. can do.

  Next, the processing unit illustrated in the user terminal B22 will be described. A processing unit in which a processing unit name similar to that of the user terminal A21 performs the same processing, and thus description thereof is omitted. When the second receiving unit 224 receives a terminal information providing command from the user terminal A, the terminal information providing unit 222 performs processing for causing the second transmitting unit 221 to transmit terminal information with reference to the storage unit 223. It is a processing unit.

  An example of a data table stored in the storage unit 223 is shown in FIG. In the storage unit 223, “terminal address” 2231, “identification number” 2232, and “control key” 2233 are stored in association with each other.

Stores “789123”, which is the identification number of the second communication means of the user terminal B, and “4ef5gh6”, which is a signal for controlling the user terminal B, is stored in the control key.

  The related movement of each processing unit shown in FIGS. 2 and 6 will be described with reference to FIG.

  The information providing device 3 that has detected the occurrence of the disaster transmits the disaster occurrence information to the receiving unit 12 of the safety confirmation device 1 (S11). The receiving unit 12 of the safety confirmation device 1 receives disaster occurrence information (S21). Based on the disaster occurrence information, the request creation unit 13 creates a response request, and the transmission unit 11 transmits the response request (S22).

  The response request transmission process (S22) will be described with reference to FIG. When the receiving unit 12 receives disaster occurrence information from the information providing device 3 (S21 in FIG. 8), the receiving unit 12 delivers the disaster occurrence information to the information extracting unit 15. The information extraction unit 15 extracts the disaster occurrence date, disaster occurrence area, and disaster scale from the disaster occurrence information, and stores them in the disaster information DB 18 in association with each other (S221).

  Subsequently, the request creation unit 13 refers to the disaster information DB 16 and searches for an occurrence area having a disaster scale equal to or greater than a predetermined threshold (S222). The predetermined threshold value may be stored in advance in a storage unit (not shown), or may be set / input from an external organization. Moreover, not only can the disaster scale be specified uniformly, but the threshold value can be changed and set for each region. For example, in a region where many elderly people live, the safety may be confirmed more accurately by setting the threshold value low.

  Subsequently, the terminal address storing the identified occurrence area in the registered area 163 is read with reference to the user DB 16 (S223).

  For example, when the threshold value is “seismic intensity 7” in S222, the request creation unit 13 refers to the occurrence area 183 of the disaster information DB 18 (FIG. 4) and searches for an occurrence area that is “seismic intensity 7” or more. In this case, “Kanto 1” corresponds. With reference to the user DB 16 (FIG. 3), the terminal address storing “Kanto 1” in the registered area 163 is searched. The request creation unit 13 reads out the terminal addresses stored in the terminal addresses 162 of the users A, B, C, and D.

  The request creation unit 13 creates a response request for the read terminal address (S224). An example of the response request screen is shown in FIG. This response request screen 1000 includes a message requesting transmission of safety information for safety confirmation and a message prompting acquisition of peripheral terminal information. For example, as illustrated in FIG. 10, a button 1001 that can acquire peripheral terminal information only by a click operation by a user and a button 1002 that can transmit safety information may be provided. Processing when the button 1001 and the button 1002 are clicked will be described later. When the request creation unit 13 creates a response request having such a screen configuration, it is possible to support a user who is in a severe mental state at the time of a disaster to reliably and easily perform an operation.

  Then, the transmission unit 11 transmits the response request created by the request creation unit 13 to the read terminal address (S225). At this time, the transmission unit 11 transmits a response request to the terminal address read from the user DB 16 as a communication address that can be received by the public wireless communication means of the user terminal 2. For example, the transmission unit reads the user A's terminal address “abc@co.jp”, the user B's terminal address “abc@co.jp”, and the user A's terminal address “def@co.jp”. ”, A response request is transmitted to the terminal address“ ghi@co.jp ”of the user C and the terminal address“ jkl@co.jp ”of the user D.

  Returning to FIG. 8, the response request transmitted by the transmission unit 11 of the safety confirmation device 1 is received by the user terminal A21 and the first reception unit 211 of the user terminal B22 (the user terminal B22 is not shown in FIG. 6). (S31, S41).

  In addition, although the case where the safety confirmation apparatus 1 transmits a response request was demonstrated above, you may make it the user terminal 2 respond spontaneously at the time of a disaster occurrence. In this case, S11, S21, S22, S31, and S41 are omitted.

  Subsequently, the terminal information acquisition unit 217 of the user terminal A21 executes acquisition of terminal information of other user terminals existing in the vicinity (S32). Further, the terminal information providing unit 222 of the user terminal B22 provides its own terminal information according to the command from the user terminal A21 (S42).

  Similarly, the user terminal B may perform the peripheral terminal information acquisition process (S32), and the user terminal A may also perform the terminal information provision process (S42). As illustrated in FIG. 8, the processing of the user terminal A and the user terminal B is different when the user B does not perform an operation on the response request (S41) due to some factor.

  The above factors are as follows: 1) The radio wave condition is unstable and the terminal cannot receive a safety information transmission request from the safety confirmation system; 2) The transmission request cannot be received due to the email reception rejection setting; 3) Even if the request is received normally, there are cases where the user does not notice that the request has been received, or 4) the user cannot perform the transmission operation due to injury.

  The peripheral terminal information acquisition process (S32) and the terminal information provision process (S42) will be described with reference to FIG.

  The response request received by the first receiving unit 212 of the user terminal A21 is displayed on the display unit 218 (S321). An example of a response request display screen at this time is shown in FIG. The terminal information acquisition unit 217 receives a peripheral information acquisition start command, which is an execution command for peripheral terminal information acquisition processing, via the input unit 219 (S322). For example, the peripheral terminal information acquisition start command is input by the user clicking on the peripheral terminal information acquisition button 1001 provided on the response request screen 1000 and is received by the terminal information acquisition unit 217.

  When the terminal information acquisition unit 217 receives the peripheral information acquisition start command, the terminal information acquisition unit 217 transmits a terminal information provision command instructing to provide the second transmission unit 214 terminal information (S323). At this time, even if the terminal information acquisition command is not input, the terminal information provision command may be transmitted when the terminal information acquisition unit 217 detects opening of the response request.

  The second receiving unit 224 of the user terminal B22 existing in the communicable range of the second communication means of the user terminal A21 receives the terminal information provision command (S421). The terminal information provision command is received by all user terminals existing within the communicable range of the short-range wireless communication means that is the second communication means of the user terminal A21.

  Then, the second reception unit 224 passes the received terminal information provision command to the terminal information provision unit 222. The terminal information providing unit 222 refers to the storage unit 223 and reads the identification number stored in the identification number 2232 (S422). The terminal information providing unit 222 issues a command for causing the second transmission unit 221 to transmit the read identification number. The second transmission unit 221 transmits the identification number read out via the short-range wireless communication network to the surroundings (S423).

  For example, the terminal information providing unit 222 reads “789123” stored in the identification number 2232 of the storage unit 223 illustrated in FIG. 7, and the second transmission unit 221 transmits the read identification number “789123”.

  Subsequently, the second reception unit 213 of the user terminal A21 receives the identification number transmitted by the second transmission unit 221 of the user terminal B22 via the short-range wireless communication network (S323). When there are a plurality of user terminals 2 within the short-range wireless communication range of the user terminal A, a plurality of identification numbers are received from the plurality of user terminals.

  With the configuration as described above, the user terminal A21 can receive the identification number of the user terminal existing in the communicable range of the second communication means (short-range communication means). As a result, the user terminal A21 can easily recognize a terminal existing in the vicinity.

  Returning to FIG. 8, the safety information creation unit 216 of the user terminal A21 creates safety information including the peripheral terminal identification number, which is the peripheral terminal information acquired in the peripheral terminal information acquisition process, and the terminal address of the user terminal A21. (S33). If multiple identification numbers are received, attach all of them.

  For example, the second receiving unit 213 of the user terminal A receives “789123” from the user terminal B. At this time, it is assumed that the identification number “456789” is received from the user terminal C and the identification number “234567” is received from the user terminal D at the same time. The received identification number is delivered to the safety information creation unit 216, and the safety information creation unit 216 attaches the received identification number to the safety information.

  Then, the safety information creation unit 216 instructs the first transmission unit 211 to transmit the safety information, and the first transmission unit 211 transmits the safety information to the safety confirmation device 1 (S34). For example, the first transmission unit 211 may transmit the safety information based on a command input by clicking a mail reply button 1002 provided on the response request screen 1000.

  The receiving unit 12 of the safety confirmation device 1 receives safety information from the user terminal A21 (S23). When receiving the safety information from the user terminal A21, the receiving unit 12 passes the safety information to the information extracting unit 15, and the information extracting unit 15 sends the email address of the user terminal A that has transmitted the safety information from the safety information, and the peripheral terminal. The identification number is extracted and stored in the safety confirmation DB 17 in association with it (S24).

  For example, the information extraction unit 15 extracts “abc@co.jp” and stores it in the safety confirmed terminal address 171 of the safety confirmation DB 17, and extracts “789123”, “456789”, “234567” and the surroundings of the safety confirmation DB 17 Stored in the terminal identification number 172.

  Subsequently, the information extraction unit 15 instructs the safety unconfirmed terminal determination unit 14 to determine the safety unconfirmed terminal, and the safety unconfirmed terminal determination unit 14 refers to the safety confirmation DB 17 to identify the identification numbers existing in the peripheral terminal identification numbers 172. Next, the terminal DB corresponding to the read identification number is searched with reference to the user DB 16 (S25).

  Then, the safety confirmation determination unit 14 refers to the safety confirmation DB 17 to determine whether the searched terminal address exists in the safety confirmed terminal address 171 (S26). If it exists, it is determined that the search is unnecessary (S26 YES), and the process ends. If it does not exist, it is determined that the terminal is a safety unconfirmed terminal that needs to be searched (NO in S26).

  For example, the safety unconfirmed terminal determination unit 14 reads “789123” present in the peripheral terminal identification numbers 172 of the safety confirmation DB 17. Then, the identification number 164 of the user DB 16 is searched to read the terminal address “def@co.jp” corresponding to “789123”. Then, it is determined whether “def@co.jp” exists in the safety confirmed terminal address 171 of the safety confirmation DB 17. Since it does not exist, the user terminal B corresponding to the terminal address “def@co.jp” is determined as a safety unconfirmed terminal that needs to be searched.

  In addition, the safety unconfirmed terminal determination unit 14 reads the terminal address “ghi@co.jp” corresponding to “456789” by the same process. Since “ghi@co.jp” exists in the safety confirmed terminal address 171 of the safety confirmation DB 17, the user terminal C determines that search is unnecessary (safety confirmed terminal). Similarly, the user terminal D corresponding to “jkl@co.jp” read based on “234567” is determined as a safety unconfirmed terminal.

  The request creation unit 13 creates a search request and instructs the transmission unit 11 to transmit a search request with the terminal address of the user terminal A that is the transmission source of the safety information as a transmission destination. The transmission unit 11 transmits a search request to the safety confirmed terminal address (S27).

  The search request is data including information on the user. At this time, the search request may be transmitted to all the safety-confirmed terminal addresses having the identified identification number of the unconfirmed safety terminal in the identification number 172 of the peripheral terminal in the safety confirmation DB 17.

  Although only the user terminal A21 and the user terminal B22 have been described in FIG. 8, other user terminals (for example, the user terminal C23 in FIG. 1) are included in the communicable range of the short-range wireless communication unit of the user terminal A21. If the user terminal D24) is present, the safety confirmation device 1 receives safety information including a plurality of identification numbers (S23). In this case, S25 to S26 are performed for each identification number, and if there is at least one unconfirmed safety terminal, a search request is transmitted (S27).

  A detailed processing flow of the search request transmission process (S27) of FIG. 8 will be described with reference to FIG.

  Based on the terminal address of the user terminal identified as a safety unconfirmed terminal in S26 of FIG. 8, the request creation unit 13 refers to the user DB 16 and reads information corresponding to the terminal address of the safety unconfirmed terminal (S271). ). At this time, information considered to be useful when the user of the safety-confirmed terminal searches is read out.

  Then, it is determined whether there are a plurality of terminal addresses of the user terminals identified as unconfirmed safety terminals (S272). If there are multiple (YES in S272), the display order is determined (S273). The display order is the order in which users of unconfirmed safety terminals are displayed on the search request screen. Based on the display order described below, the request creation unit 13 creates a search request screen (S274). If the number is single (S272 NO), the search request screen is created as it is (S274). The created search request and the read destination address are transferred to the transmission unit 11, and the transmission unit 11 transmits the search request to the safety confirmed terminal (S275).

  Returning to FIG. 8, the first receiving unit of the user terminal A21 receives the search request (S35). Subsequent processing (A and B) will be described later.

  Through the processing as described above, it is possible to identify a safety-confirmed terminal that is highly likely to have a safety-unconfirmed terminal in the vicinity, and request the specified safety-confirmed terminal to search for a safety-unconfirmed terminal. It is possible to support confirmation of the safety of the person who has not confirmed safety earlier.

  The identified safety confirmed terminal searches for the unconfirmed safety terminal, thereby helping to easily grasp the user status of the unconfirmed safety terminal that did not transmit the safety information due to the above-mentioned factors. be able to.

  Hereinafter, a search request display screen transmitted from the safety confirmation device 1 to the user terminal A21 will be described. FIG. 13 shows an example of a search request screen created by the request creation unit 13 in S275 of FIG.

  The search request screen 131 is a display example based on a display order determined using data stored in the group 165 to which the user DB 16 belongs. Referring to the user DB 16, the user A of the safety-confirmed terminal performing the search belongs to “..Electrical Personnel Department”, and the user B of the unconfirmed safety terminal to be searched is “..Electric Personnel Department”. User D belongs to “..Electricity Sales Department”. From the user B of the safety unconfirmed terminal that belongs to the same affiliation group as the user A of the safety confirmed terminal, the same affiliation is displayed in the previous order.

  From the above configuration, it is highly likely that the user A who is searching has grasped characteristics such as the face of the user of the unconfirmed safety terminal that is the search target, and the user B who is predicted to be easily searched The search can be supported efficiently.

  Search request screens 132 and 133 are display examples of search request screens in the display order determined by changing the display order. When there are a plurality of safety-confirmed terminals that recognize similar safety-unconfirmed terminals in the vicinity, the display order of the search target person on the search request screen is changed for each safety-confirmed terminal.

  For example, it is assumed that the user terminal X transmits safety information, and the safety confirmation device 1 transmits a search request 132 for the unconfirmed safety terminals M, N, and O to the user terminal X based on the safety information. On the other hand, the user terminal Y transmits safety information, and the request creation unit 13 of the safety confirmation device 1 starts creating a search request for the unconfirmed safety terminals M, O, and P based on the safety information. At this time, the identification information of the user terminals M and O is also present in the identification information 172 of peripheral terminals of other safety-confirmed terminals (user terminals X) in the safety confirmation DB. Therefore, when the display order is determined, the display order of the users of the unconfirmed safety terminals that are subject to search is duplicated and displayed.

  In the search request screen of the user terminal X, a search is requested to “Mr.” “Mr. N” and “Mr. O”. On the search request screen of the user terminal Y, for example, “P-san → O-san → M-san” are displayed in this order. “Mr. M” and “Mr. O” included in the search request of the user terminal X are displayed in a display order lower than the user “Mr. P” of the user terminal not included in the search request of the user terminal X. Is done.

  With the above configuration, it is possible to prevent the search from being concentrated on a specific safety unconfirmed terminal, and to help efficiently perform safety confirmation. These display order determination methods may be set in advance, and several determination methods may be used in combination.

  Based on the determined display order, the search request screens created by the request creation unit 13 are 131, 132, and 133. The search request screen may include the name 1311 of the user of the unconfirmed safety terminal and the personal information 1312 as information that is considered useful when the user of the safety confirmed terminal searches. Furthermore, the information of the URL 1313 may be included.

  In the URL 1313 shown in FIG. 13, a status page of a person who has not confirmed safety is provided. This URL is stored in advance in the user URL 167 of the user DB 16. Alternatively, for the user terminal that the safety unconfirmed terminal determination unit 14 determines to be a safety unconfirmed terminal, a situation creation update unit 19 URL is uniquely generated, and is associated with the user name 16 of the user DB 16, and the personal URL 167 To store. In this case, it is assumed that no data is stored in the user ULR 16 of the user DB 16 before the disaster occurs.

  A display example of the status page is shown in FIG. In this, the latest safety confirmation status (1411, 1421) of the person who has not confirmed safety is displayed. The latest safety confirmation status is information periodically created by the status creation update unit 19 with reference to the safety confirmation DB 17 every predetermined time.

  The situation creation / update unit 19 periodically searches the safety confirmation DB 17, and if the terminal address of the unconfirmed safety terminal does not exist in the safety confirmed terminal address 171, determines that the safety has not yet been confirmed. Create and provide a display screen. If the terminal address of the safety unconfirmed terminal exists in the safety confirmed terminal address 171, it is determined that the safety has already been confirmed, and a display screen 142 is created and provided.

  If the latest status is unconfirmed (141), a message for requesting a search is included. Then, the control key 1412 and information 1413 for executing a predetermined program may be displayed. The control key is a signal used for authentication for the safety-confirmed terminal A to control the safety-unconfirmed terminal B. The predetermined program is a program for issuing a warning to the searching user and the searched user, such as sounding the buzzer of the user terminal B or activating the vibration function. Hereinafter, the buzzer will be explained.

  When the user A of the user terminal A21 viewing the search request screen 131 in FIG. 13 inputs an instruction to access the URL 1313, the user terminal A displays 141 in FIG. When the user A of the user terminal A21 inputs the buzzer sounding (1413 YES) for the display of the status page 141 1413, the safety unconfirmed person terminal B22 is predetermined. Run the program and sound the buzzer.

  Although the buzzer sounding flow will be described later, the user A can easily and quickly search for the user B by controlling the user terminal B22 and sounding the buzzer. If there is, user B can be prompted to operate.

  If safety has already been confirmed (142), a message indicating that the search is unnecessary is displayed.

  FIG. 15 is a functional diagram of a user terminal device 2 according to another embodiment of the present invention. It is a functional diagram regarding the Example in the case of performing execution of the predetermined | prescribed program illustrated to 1413 of FIG. Although the user terminal A21 and the user terminal B22 are described as having different processing units, the user terminal A21 and the user terminal B22 have the same and all processing units.

  FIG. 15 illustrates only a processing unit necessary for explaining the processing of the user terminal A21 that executes a predetermined program and the user terminal B22 that executes the predetermined program. The description of the processing unit that overlaps with FIG. 6 and the movement of each unit up to the reception of the search request shown in FIG. 8 are the same as those in FIG. 6 and FIG. And each processing part shall further be provided with the function demonstrated from now on.

  The user terminal A21 can communicate with the safety confirmation device 1 via a network (not shown), and can further communicate with the user terminal B22 in near field. First transmission unit 211, first reception unit 212, second reception unit 213, second transmission unit 214, safety information creation unit 216, terminal information acquisition unit 217, display unit 218, input unit 219, and other terminal control unit 210 Have. Furthermore, it has a processing unit shown only in the user terminal B22.

  The user terminal B22 can communicate with the safety confirmation device 1 via a network (not shown), and can further communicate with the user terminal A21 via short-range wireless communication. It has a second transmission unit 221, a storage unit 223, a second reception unit 224, an authentication unit 225, and an alarm unit 226. Furthermore, it has the process part shown only in user terminal A21.

  First, a processing unit related to processing for executing a predetermined program in the user terminal A21 will be described.

  The first receiving unit is a processing unit that receives data from the safety confirmation device 1. The second transmission unit 214 is a processing unit that performs processing for transmitting data to other user terminals through short-range wireless communication. The other terminal control unit 210 is a processing unit that performs a process of generating a signal for controlling another user terminal. The display unit 218 is a processing unit that displays information received by the first receiving unit 212, and corresponds to a display. The input unit 219 is a processing unit that accepts input from the outside, and corresponds to the button of the user terminal 2.

  Next, a processing unit related to processing for executing a predetermined program in the user terminal B22 will be described. Moreover, since the process part which has described the process part name similar to user terminal A21 performs the same process, description is omitted.

  The authentication unit 225 is a processing unit that performs authentication based on the data received by the second reception unit 224. The storage unit 223 is a storage unit that stores information related to the user terminal B22. The alarm unit 226 is a processing unit that executes a predetermined program and sounds a buzzer when the authentication unit 225 authenticates.

  Next, the movements associated with each processing unit from when the user terminal A21 receives a search request from the safety confirmation device 1 to when the user terminal B22 executes a predetermined program will be described with reference to FIG. Hereinafter, the predetermined program will be described as a program that sounds a buzzer.

  When the first receiving unit 212 receives the search request in S35 of FIG. 8, for example, the screen example of FIG. 13 is displayed as the received information on the display unit 218 of the user terminal A21 (S50). And the other terminal control part 210 receives selection of the user terminal of search object from the user A of user terminal A21 via the input part 219 (S51).

  If 1413 of the status page 141 of the selected search target user terminal is Yes, the other terminal control unit 210 controls the search target user terminal from the input unit 219 to sound the buzzer The other terminal control command is received (S52). Further, the control key input is accepted (S53). Then, the other terminal control unit 210 generates another terminal control signal including the received control key (S54).

  For example, when the user terminal A rings the buzzer of the user terminal B, which is a safety unconfirmed terminal, the other terminal control unit 210 displays “1.B displayed on the search request screen 131 via the input unit 219. Accept URL selection for "". The display unit 219 displays the status page 141 of the person who has not confirmed safety. And other terminal control part 210 receives selection of execution of a buzzer ringing via input part 218 (selecting YES of 1413). Further, the other terminal control unit 210 receives the input of the control key (1412) and creates another terminal control signal including the control key. Further, when the other terminal control unit 210 accepts the selection of the buzzer sounding, the other terminal control signal including the control key may be generated. In this case, S53 is omitted.

  It is assumed that the search request received by the user terminal A21 includes the control key “4ef5gh6” (FIGS. 14 and 1412). Then, the other terminal control unit 210 generates another terminal control signal including “4ef5gh6”.

  The other terminal control unit 210 passes the other terminal control signal generated in this way to the second transmission unit 214, and the second transmission unit 214 transmits the signal via the short-range wireless communication network (S55). At this time, it is received by all user terminals existing within the communicable range of the short-range wireless communication means. The following description will be specifically made when user terminal B22 receives it.

  The second receiving unit 224 of the user terminal B22 existing in the communicable range of the short-range wireless communication means of the user terminal A21 receives the other terminal control signal (S61). The second receiving unit 224 passes the other terminal control signal to the authenticating unit 225, and the authenticating unit 225 extracts the control key from the received other terminal control signal, and refers to the control key 2233 (FIG. 7) of the storage unit 223. It collates with the extracted control key (S62). If the two match, the authentication is successful (S62 YES), and the alarm unit 226 is notified of the authentication. Then, the alarm unit 226 of the user terminal B22 executes a predetermined program and sounds a buzzer (S63). If the authentication fails (S62 NO), the process is terminated as it is.

  For example, it is assumed that the control key “4ef5gh6” is included in the other terminal control signal received by the user terminal B (FIGS. 14 and 1412). When the authentication unit 225 refers to the storage unit 223 of the user terminal B22, “4ef5gh6” is stored in the control key 2233. The authentication unit 225 compares the two, and determines that the authentication is successful because they match. The alarm unit 226 is notified that the authentication is successful. In response to this, the alarm unit 226 sounds a buzzer.

  On the other hand, the user terminal C existing in the communicable range of the short-distance wireless communication means of the user terminal A21 also receives another terminal control signal including the control key “4ef5gh6”. An authentication unit (not shown) of the user terminal C refers to a storage unit (not shown) and performs verification. In this case, it is determined that the authentication has failed because they do not match. Therefore, the buzzer of the user terminal C does not ring.

  With the above configuration, the buzzer of the user terminal B22, which is a safety unconfirmed terminal, can be sounded under the control of the user terminal A21. Accordingly, it is possible to easily and quickly search for the user B by the user A and to prompt the user B to transmit safety information when the user B is forgotten.

  The embodiment of the present invention is not limited to the above.

  For example, the safety confirmation device 1 does not have to include all the processing units illustrated in FIG. 2 on one housing, and one or several processing units are mounted on other computers that are communicably connected to each other. It doesn't matter.
