The type 1507 categorizes the type of the case, and the received data may be classified in advance, or may be assigned by the present system based on the received data. If it cannot be classified, it will be blank.

  Next, the region specifying dictionary information will be described with reference to FIG. 13 (refer to FIG. 1 as appropriate). FIG. 13 shows the data structure of the region specifying dictionary information. As shown in FIG. 13, the area specifying dictionary information 1600 includes mesh identification information 1601 and case occurrence area specifying information 1602.

  The mesh identification information 1601 is identification information uniquely assigned to a mesh for identifying a mesh in which a region for monitoring the monitored person mobile terminal 8 is divided. The incident occurrence area specifying information 1602 is information for specifying an area, and may be anything as long as it is information specifying a place. For example, as shown in FIG. 13, in addition to the method of indicating the north end and the south end of the mesh by latitude and the west end and the east end by longitude, it is possible to use a local telephone number, a postal code, or the like.

  Next, monitoring device management information will be described with reference to FIG. 14 (see FIG. 1 as appropriate). FIG. 14 shows the data structure of the monitoring device management information. As shown in FIG. 14, the monitoring device management information 1700 includes monitoring device identification information 1701 and incident occurrence area specifying information 1702.

  The monitoring device identification information 1701 is identification information for uniquely specifying the monitoring device 6. The mesh identification information 1702 is identification information for uniquely identifying a mesh. In addition to these, the monitoring device identification information 1701 may include an item regarding the installation location of the monitoring device 6. If this installation location item is used, information relating to the installation location of the monitoring device 6 that has detected the monitored person portable terminal 8 can be notified to the supervisor terminal 2.

  Next, the log data protection management information will be described with reference to FIG. 15 (refer to FIG. 1 as appropriate). FIG. 15 shows the data structure of log data protection management information. As shown in FIG. 15, the log data protection management information 1800 includes a corresponding 1810, an accessibility 1820, a backup completion 1830, and a lock release 1840 for each combination of A_ID 1801 and monitoring device identification information 1802. Have items. In each item, “◯” is set for applicable items, “×” is set for not applicable items, and “−” is set for unexamined items.

  Corresponding 1810 indicates whether or not the monitoring device 6 is an occurrence area of the case specified by A_ID 1801. Accessibility 1820 indicates whether or not the management apparatus 4 can access the monitoring apparatus 6 via the network. The backup completion 1830 indicates whether or not the management device 4 has completed the downloading of data from the monitoring device 6. Lock release 1840 indicates whether the management device 4 has released the data protection state of the monitoring device 6.

  Next, referring to FIG. 16 (refer to FIG. 1, FIG. 12, FIG. 13 and FIG. 14 as appropriate), the process of confirming the location of the monitored person and notifying the location will be described. FIG. 16 is a flowchart showing the flow of processing for confirming the location of the monitored person and notifying the location in the monitoring system.

  As shown in FIG. 16, first, the management device 4 performs a case collection process (S100). That is, the management device 4 acquires data indicating that the case E has occurred at the location L at a certain time T from the case acquisition device 12, the case detection device 13, and the like. Since the acquired data is not always obtained in a fixed data format, the occurrence location, the occurrence time, the case type, the case contents, etc. are stored in the case information 1500 by a predetermined analysis process. Subsequently, the management device 4 performs a local coordinate system conversion process (S200). In other words, the management device 4 converts the location 1505 into the coordinate system data used in the present system based on the area specifying dictionary information 1600 registered in advance. For example, an area for monitoring a person to be monitored in this system is divided into meshes in advance, and unique identification information (mesh identification information 1601) is assigned to each mesh, and a character string (incident occurrence area specifying information 1602) and mesh (mesh) The correspondence relationship with the identification information 1601) is stored in the area specifying dictionary information 1600 in advance. In this way, the mesh identification information 1601 indicating the occurrence location can be obtained by combining the character string indicating the occurrence location 1505 and the case occurrence area specifying information 1602 for comparison. FIG. 13 shows the north and south ends of the mesh as latitude and the west and east ends as longitude as the incident occurrence area specifying information 1602. In this case, it is determined whether or not the location specified by the latitude and longitude indicated in the occurrence location 1505 belongs to the region specified by the latitude and longitude of the incident occurrence region specifying information 1602.

  Next, the management device 4 performs target monitoring device extraction processing (S300). In other words, the management device 4 identifies the monitoring device 6 installed at the location where the incident occurred from the monitoring device management information 1700 using the mesh identification information obtained in S200. Then, the management device 4 performs data protection processing (S400). That is, the management device 4 overwrites or deletes the data indicating the location of the monitored person 10 stored in the monitoring device 6, that is, the monitoring device 6 specified in S 300, based on the monitoring device identification information 1701 obtained in S 300. prevent. Details of this processing will be described later with reference to FIG. The management device 4 stores data indicating the location of the monitored person 10 acquired from the monitoring device 6 in the log data 1900. Moreover, the management apparatus 4 performs monitored person location information generation processing (S500). That is, the management device 4 generates the location information 2000 as location information 2000 indicating whether the monitored person 10 is in the vicinity of the location L or whether it is in another location. Subsequently, the management device 4 performs location information distribution registration processing (S600). That is, the management device 4 transmits the stored location information 2000 to a destination registered in advance in the delivery destination information 2100 or registers it in the WEB server, so that the monitor 9 determines the location of the monitored person 10. Register or distribute data for availability.

  The log data 1900 is discarded after being stored for a predetermined period or for a specified period after the log data is acquired. By not deleting the log data 1900 immediately after S600, a person who has not previously registered with the service can obtain a clue of whereabouts after the occurrence of the incident.

  Next, details of the data protection process will be described with reference to FIG. 17 (refer to FIGS. 1 and 15 as appropriate). FIG. 17 is a flowchart showing details of data protection processing in the monitoring system.

  As shown in FIG. 17, the management device 4 first calculates the data protection target time (data protection time condition) (S411), and updates the corresponding 1810 of the log data protection management information 1800 (“O: Corresponding”). (S412). For example, the management device 4 holds difference time specifying information in which a difference time is associated with each case importance, and data protection is performed by subtracting the difference time from the occurrence time 1506 acquired from the case information 1500. It is also possible to calculate the time to end data protection by adding the difference time to the occurrence time 1506 acquired from the case information 1500. Then, the management device 4 transmits a data protection command to the monitoring device 6 (S413). This data protection command includes the calculated data protection target time.

  When the monitoring device 6 receives the data protection command (S431), it returns the availability of access (S432), and the management device 4 that receives it returns the availability of the log data protection management information 1800 based on the availability of the returned access. 1820 is updated (S414). Subsequently, the monitoring device 6 performs a data protection activation process for preventing data that conforms to the data protection time condition received from the management device 4 from being overwritten and deleted (S433), and the monitoring device side network network In a state where communication using 5 is possible, the monitoring device 6 performs data transmission (S434). That is, the monitoring device 6 transmits data corresponding to the data protection target time received from the management device 4 to the management device 4.

  The management device 4 receives data (S415) and stores the received data (S416). Subsequently, the backup completion 1830 of the log data protection management information 1800 is updated (updated to “◯: applicable”) (S417), and a data protection release command is transmitted (S418). The monitoring device 6 receives the data protection release command (S435), and performs data protection release activation processing (S436). By this data protection cancellation activation process, the data protection cancellation process is executed, and the state in which the overwriting deletion of data is prevented by the data protection process is canceled. In addition, the monitoring device 6 transmits a lock release completion notification to the management device 4 (S437).

  In the above, the flow of the process in which the management device 4 transmits the data protection command has been shown. As another method, for example, the case detection device 13 receives the data in which the case has occurred, and around the case detection device 13. A method is also conceivable in which an instruction for prohibiting data writing is transmitted to the installed monitoring apparatus 6, and the monitoring apparatus 6 transmits the corresponding data to the management apparatus 4 based on the received instruction.

  As another method, there is also a method in which the monitoring device 6 transmits log data to the management device 4 at regular intervals. In this case, the management device 4 confirms the reception status of the log data from the monitoring device 6 at regular intervals, and when the transmission from the monitoring device 6 stops, executes the data protection activation process of S433.

  Furthermore, as another method, when the communication network (monitoring device side network 5) between the monitoring device 6 and the management device 4 is stopped, the portable terminal is connected to the monitoring device 6 using a portable terminal or the like. There is also a method of acquiring data from the monitoring device 6 by enabling communication and storing the acquired data in the management device 4 using the function of the portable terminal. As a method for storing data from the mobile terminal to the management apparatus 4, there are a method of transmitting using a communication function of the mobile terminal, a method of transmitting the mobile terminal connected to the management apparatus 4 using a cable, and the like.

  Next, the case report screen will be described with reference to FIG. 18 (see FIG. 1 as appropriate). FIG. 18 is a diagram showing a case report screen.

  As shown in FIG. 18, a case report screen 2300 is a display example of a screen for inputting word-of-mouth information when a user transmits word-of-mouth information related to a case to the present system. The input contents are 2310 when, 2320 where, and 2330 where there was. When the data about 2310 is input, there are a column for inputting how many minutes before the current time and a column for inputting the date and time numerically. The area where data relating to 2320 is input includes an area for instructing acquisition of the current location using GPS, an area for inputting a keyword indicating a place such as a landmark, and an area for inputting an address, a zip code, and the like. The area for inputting the data relating to what 2330 has occurred is an area for displaying a pre-registered list, for example, “There was a suspicious person”, “There was a person with a weapon”, “Traffic accident”, “Fire”, “Other”, etc. There is also an area for entering keywords.

  After the above data is input, the input data is transmitted to the incident detection device 13 by selecting the transmission button 2340. When the cancel button 2350 is selected, the input data is not transmitted and this screen is not displayed.

  Although the present embodiment has been described above, the monitoring device 6 can transmit data to the collection device that collects the detection information, and the detection information corresponding to the detection time that matches the data protection time condition is collected by the collection device. It is also good to do. Further, the collection device can communicate with the storage device via a network different from the network where the management device 4 and the monitoring device 6 can communicate, and the collected detection information is stored via the network. It may be transferred to the device. In addition, the monitoring device 6 can communicate with the storage device via a network different from the network in which the management device 4 and the monitoring device 6 can communicate, and corresponds to a detection time that matches the data protection time condition. The detection information may be transferred to the storage device via the network. If the monitoring device 6 determines that the detection information corresponding to the detection time that matches the data protection time condition is not stored in its own storage unit, the monitoring device 6 transfers the data protection time condition to the other monitoring device 6. It may be entrusted to confirm the location of the monitored person 10. The timing at which the management device 4 transmits data to the supervisor terminal 2 may be immediately after the data is acquired from the supervisor device 6 or may be after receiving an inquiry from the supervisor terminal 2.
