To be done. The evacuation action support process will be described later in detail with reference to FIG.

  First, symbols (for example, Cm) representing data and the like used below will be described. At least one uppercase alphabet (for example, C) means a code for identifying data or the like. A lower case alphabet (for example, m) means a subscript.

  FIG. 2 is a time chart illustrating a procedure of risk level / risk range calculation processing according to the first embodiment of this invention.

  First, when a crime / disaster occurs, the crime / disaster information distribution processing unit 130 of the crime / disaster information distribution system 110 distributes the crime / disaster information Ia (a ≧ 1) to the risk calculation system 111. The distributed crime / disaster information Ia is input to the crime / disaster extraction processing unit 131 of the risk calculation system 111 (200). The crime / disaster information extraction processing unit 131 includes the portion F (Ia) indicating the characteristics of the crime or disaster included in the crime / disaster information Ia, the time T (Ia) when the crime / disaster occurred, and the occurrence of the crime / disaster. A part P (Ia) indicating a place is extracted (201). F (Ia) includes at least a crime or disaster aspect. When Ia is criminal information, F (Ia) may include the criminal's characteristic clothes, age, weapon, moving means, and the like.

  Next, the crime / disaster extraction processing unit 131 transmits the extracted F (Ia), T (Ia), and P (Ia) to the risk / risk range calculation processing unit 133 (202).

  Next, the risk level / risk range calculation processing unit 133 calculates the risk level D (Ia). First, the risk / risk range calculation processing unit 133 extracts a crime or disaster mode Cb (b ≧ 1) from F (Ia) (203). F (Ia) includes b (b ≧ 1) aspects of crime or disaster.

  Next, the risk level / risk range calculation processing unit 133 extracts risk level information D (Cb) corresponding to the crime or disaster mode Cb from the risk level / risk range DB 132 (204, 205). Next, the risk level / risk range calculation processing unit 133 performs the risk level D () of the crime / disaster information Ia based on the risk level information D (Cb) of all crimes or disasters included in F (Ia). Ia) is calculated (206).

  Various methods are conceivable for calculating the risk level D (Ia). For example, the sum of the risk information D (Cb) in the form of crime or disaster may be D (Ia). The average value of D (Cb) may be D (Ia). Further, the maximum value of D (Cb) may be D (Ia). Any method may be selected as a method for calculating the risk D (Ia) depending on the policy of system operation.

  The risk information D (Cb) is a character string in which numerical values set based on preset criteria or the magnitude relation of the risk are ordered. If Cb is not registered in the risk / risk range DB 132, D (Cb) is determined by contacting an administrator who has the authority to determine the risk, or automatically according to preset criteria. Is calculated automatically. The method for calculating the degree of risk and the above-mentioned standard are set in advance according to the policy of system operation.

  Further, when a crime occurs, the criminal feature Gc (c ≧ 1) may be extracted from the crime feature F (Ia). Here, F (Ia) includes c crime features. Further, the risk level D (Ia) may be calculated based on the risk level information D (Gc) corresponding to the criminal feature Gc. In this case, the sum of the risk information D (Cb) corresponding to the crime mode and the risk information D (Gc) of the criminal characteristics may be D (Ia). Further, the average value of D (Cb) and D (Gc) may be D (Ia). Further, the maximum value of D (Cb) and D (Gc) may be D (Ia).

  Next, the risk level / risk range calculation processing unit 133 calculates the risk range R (Ia). First, the risk level / risk range calculation processing unit 133 extracts risk range information R (Cb) corresponding to the crime or disaster mode Cb from the risk level / risk range DB 132 (207, 208). The danger range information R (Cb) is a numerical value set according to a preset criterion, a character string in which the magnitude relations of the danger ranges are ordered, or a correction value.

  The correction value is a value for correcting the danger range calculated by the crime or disaster mode Cb. For example, it is a value set by moving means and / or weapons included in the criminal feature Gc extracted from the crime feature F (Ia), and when the moving means is an automobile, R (automobile) = plus radius 20 When a knife is held in a meter or a weapon, R (blade) = plus radius 30 meters.

  If Cb is not registered in the risk level / risk range DB 132, an inquiry is made to an administrator who has the authority to determine the risk range. R (Cb) is determined by making an inquiry to an administrator or the like. Note that R (Cb) may be automatically calculated based on a preset criterion. The method for calculating the danger range and the above-described criteria are set in advance according to the policy of system operation.

  Next, the risk range R (Ia) of the crime / disaster information Ia is calculated based on the risk range information R (Cb) of all crimes or disasters included in F (Ia) (209). Various methods can be considered as a method of calculating the danger range R (Ia). For example, the sum of the risk range information R (Cb) in the form of crime or disaster may be R (Ia). The average value of R (Cb) may be R (Ia). Further, the maximum value of R (Cb) may be R (Ia). Any method may be selected as the calculation method of these danger ranges R (Ia) depending on the policy of system operation.

  Further, the danger range R (Ia) may be calculated using a correction value. For example, when the criminal feature Gc is used as a correction value, the sum of the risk range information R (Cb) of the crime or disaster aspect and the risk range information R (Gc) of the criminal feature may be R (Ia) Good. Further, the average value of R (Cb) and R (Gc) may be R (Ia). Further, the maximum value of R (Cb) and R (Gc) may be R (Ia).

  Further, the risk level and the risk range may be calculated in consideration of the crime / disaster occurrence time T (Ia) and / or the crime / disaster occurrence location P (Ia). For example, when T (Ia) represents night, the risk level is increased and / or the risk range is increased. Also, if crimes / disasters frequently occur in the vicinity of P (Ia) and / or if a high-risk crime / disaster has occurred in the past, increase the risk and / or Or adjustments such as widening the danger range are made.

  After the risk D (Ia) and the risk range R (Ia) of the crime / disaster information Ia are calculated, the risk / risk range calculation processing unit 133 calculates the crime / disaster risk calculated for the crime / disaster information Ia. The degree information D (Ia) and the risk range information R (Ia) are registered in the crime / disaster information DB 121 (214, 215). In this case, the risk level / risk range calculation processing unit 133 inquires of the address / latitude / longitude conversion processing unit 134 to change the crime / disaster occurrence location P (Ia) format (address format or latitude / longitude format, etc.) -You may convert into the format prescribed | regulated by danger range DB132 (210-213).

  The crime / disaster information Ia may not include information that can specify the occurrence location in detail. In this case, the danger range is determined within the range of information obtained.

  FIG. 3 is a diagram showing a danger range set from a range of occurrence locations included in crime / disaster information. For example, when the crime / disaster information Ia includes up to the address, the risk range is determined from the end of the address area in consideration of the area specified by the address.

  FIG. 4 shows the risk level information D (Cb) corresponding to the crime or disaster mode Cb stored in the risk level / risk range DB 132, the risk range information R (Cb), and the risk level information D corresponding to the criminal characteristic Gc. It is an example of (Gc) and danger range information R (Gc).

  The risk level / risk range DB 132 includes a risk level and a risk range associated with any one of a crime or disaster aspect and a criminal characteristic. The risk level information and the risk range information included in the risk level / risk range DB 132 are determined before the risk level / risk range calculation processing is executed, and are stored in the risk level / risk range DB 132.

  The method for determining the risk level and the risk range information may be determined by having a general performer input in advance by the watcher 102, which is determined by taking a questionnaire. Further, it may be determined with reference to statistical information on crime / disaster (criminal / disaster addictiveness, number of crimes / disaster developments after the occurrence of crime / disaster, etc.). Any method may be selected as the method for determining the risk level and risk range information depending on the policy of system operation.

  FIG. 5 is an example of address and latitude / longitude information stored in the address DB 135. The address DB 135 includes an address and a converted value. The converted value is a value obtained by converting the address into a format (for example, latitude / longitude information) stored in the risk / risk range DB 132.

  FIG. 6 is an example of crime / disaster information stored in the crime / disaster information DB 121.

  The crime / disaster information DB 121 includes an occurrence location, an occurrence time, a crime / disaster, a feature, a risk level, and a risk range. The occurrence location is a converted value obtained by converting the location where the crime / disaster occurs based on the address DB 135. The occurrence time is the time when the crime / disaster occurred. Crime / disaster is a form of crime or disaster that has occurred. The feature is a feature of the criminal when a crime occurs. The risk level and the risk range are the risk level and the risk range calculated by the risk level / risk range calculation process.

  Next, the danger determination process will be described. The risk determination process includes a risk level calculation process, an evacuation route generation process, a danger information map generation process, and an information distribution process.

  The risk level calculation process is the crime / disaster risk of crime / disaster information Ia (a ≧ 1) registered in the crime / disaster information DB 121 in advance and the position PC of the watch target person 101 at the time TC of the watch target person 101. Based on the degree information D (Ia), the danger range information R (Ia), the occurrence location P (Ia), and the occurrence time T (Ia), the danger degree DC of the current time TC of the watching target person 101 is calculated.

  The risk determination process is repeated at a predetermined timing (for example, at a predetermined time interval). For example, the time interval may be shortened from evening to night, depending on the system management policy.

  FIG. 7 is a time chart showing the procedure of the risk degree calculation process.

  First, the danger determination processing unit 143 of the danger determination system 114 inquires of the position inquiry processing unit 145 of the terminal position measurement system 116 about the position of the watching target person 101 (300). The position inquiry processing unit 145 observes the position PC of the watching target person 101 via the position measurement processing part 153 of the terminal 118 of the watching target person 101 (301 to 303). Then, the obtained position PC and current time TC are returned to the risk determination processing unit (304).

  Next, the danger determination processing unit 143 queries the crime / disaster information DB 121 for crime / disaster information that includes the position PC of the person 101 to be watched within the danger range (305, 306). At this time, when the threshold value TH of the risk level is set by the watcher 102, the risk level / risk range DB extracts only crime / disaster information exceeding TH (307).

  As a result of inquiring to the crime / disaster information DB 121, if the position PC of the watching target person 101 is not included in any of the risk range information, the watching target person 101 has a risk level of 0, and the risk determination process ends. To do. On the other hand, as a result of the inquiry, if there is crime / disaster information Id (d ≧ 1) that includes the PC within the risk range, the crime / disaster information DB 121 returns the crime / disaster information Id to the risk determination processing unit 143 (308). ).

  Next, the risk determination processing unit 143 calculates the risk DC of the watching target person 101 at the current time TC based on the risk D (Id) of the crime / disaster information Id (309).

  Various methods can be considered as a method of calculating DC. For example, the sum of D (Id) may be DC. The average value of D (Id) may be DC. The maximum value of D (Id) may be DC. Further, D (Id) may be determined in consideration of the distance between the position PC of the person to be watched 101 and the place P (Id) where the crime / disaster Id occurs. Any DC calculation method may be selected according to the system operation policy.

  Next, the evacuation route generation process will be described. In the evacuation route generation process, the evacuation route from the current position to the safe place (for example, the rescuer 103 or the evacuable place 104) is generated by the watching target person 101. All crime / disaster information Ie (e ≧ 1) that overlaps with the current position PC of the person to be watched over 101 and the circle C with the radius L centered on the PC, and the evacuation area Ef included in the circle C, and relief Based on the person Sg, an evacuation route ER that can be used for the watching target person 101 to evacuate safely is generated. The procedure of the evacuation route generation process will be described below.

  FIG. 8 is a time chart showing the procedure of the evacuation route generation process.

  First, the danger determination processing unit 143 transmits an evacuation route generation request to the evacuation route generation processing unit 139 of the map generation system 112 (400). The evacuation route generation processing unit 139 inquires of the evacuation site DB 140 about the position of the evacuable site 104. Further, the position inquiry processing unit 145 of the terminal position measurement system 116 is inquired about the position of the rescuer 103. As a result of the inquiry, the evacuation route generation processing unit 139 obtains all the evacuable places Ef and the rescuers Sg included in the circle C within the radius L around the current position PC of the person to be watched 101 (401 to 404). ).

  In this case, either Ef or Sg includes at least one evacuation site or rescuer. There are various methods for determining the radius L. For example, the minimum distance including at least one rescuer 103 or the evacuable place 104 around the current position PC of the watching target person 101 may be used. Moreover, it is good also as the distance of position PC of the monitoring target person 101 and the destination of the monitoring target person 101. The method for determining these radii L is set in advance according to the policy of system operation.

  Next, the evacuation route generation processing unit 139 makes an inquiry to the crime / disaster information DB 121 and obtains all crime / disaster information Ie that overlaps the circle C and the risk range (405, 406).

  The evacuation route generation processing unit 139 generates an evacuation route based on the obtained evacuable place Ef, the rescuer Sg, and the crime / disaster information Ie (407). Specifically, all routes that can move from the current position PC of the watching target person 101 to the evacuable place Ef are all escape routes ER (Ef) or all of the routes that can move from the watching target person's current position PC to the rescuer Sg. Let the route be the evacuation route ER (Sg).

  At this time, the evacuation route generation processing unit 139 calculates the risk level for the evacuation route according to the risk level and risk range of the crime / disaster information Ie that passes through (408). For example, when the evacuation routes ER (Ef) and ER (Sg) pass through the danger range of the crime / disaster information Iz (z ≧ 1), the sum, average, and maximum of the danger levels D (Iz) of all the evacuation routes D (ER (Ef)) and D (ER (Sg)) are calculated by at least one of the value and the product of the distance X passing through the danger range and the danger degree D (Iz). As a calculation method of D (ER (Ef)) and D (ER (Sg)), any method may be selected depending on the policy of system operation.

  FIG. 9 is a diagram illustrating the relationship between the evacuation route, the risk range of crime / disaster information Iz, and the risk level. Specifically, it represents a crime / disaster that passes when the child heads to the evacuable place 104 or the rescuer 103. The distance X is a distance that passes through the danger range as described above.

  Next, the evacuation route generation processing unit 139 returns the generated evacuation route ER (Ef) and ER (Sg) to the risk determination processing unit 143 (409).

  Next, the risk determination processing unit 143 ranks the generated evacuation routes according to a certain standard (410). For example, the order of the evacuation routes is assigned in order to safely perform the evacuation action in consideration of at least one of the risk of the evacuation route, the length of the evacuation route, the number of people on the evacuation route, and the number of people on the evacuation route.

  Next, the danger information map generation process will be described. In the danger information map generation process, the map generation processing unit 138 of the map generation system 112 performs the crime / disaster information Ie (e ≧ 1), PC included in the radius L centered on the current position PC and PC of the person 101 to be watched over. Is generated by the evacuable place Ef (f ≧ 1) included in the radius L centered on the PC, the rescuer Sg (g ≧ 1) included in the radius L centered on the PC, and the evacuation route generation processing unit 139. A danger information map DM including the evacuation routes ER (Ef) and ER (Sg) is generated.

  FIG. 10 is a time chart showing the procedure of the danger information map generation process.

  The risk determination processing unit 143 transmits a risk information map generation request to the map generation processing unit 138 of the map generation system 112 (500). The map generation processing unit 138 includes the current position PC of the person to be watched 101, crime / disaster information Ie (e ≧ 1) included in the circle C having the radius L around the PC, and the evacuable places Ef included in the circle C. (F ≧ 1), rescuer Sg included in circle C (g ≧ 1), evacuation routes ER (Ef) and ER (Sg) generated by the evacuation route generation processing unit 139, and the order of evacuation routes are dangerous Received from the determination processing unit 143 (501 to 506).

  Further, the map generation processing unit 138 makes an inquiry to the map DB 141 of the map generation system 112 and obtains a city map including at least roads and buildings in an area with a radius L centered on the current position PC of the watching target 101 (507, 508). The map generation processing unit 138 generates a map including all the information described above, and returns the generated map to the risk determination processing unit 143 (509, 510). The generated map is called a danger information map DM.

  The danger information map DM may be narrowed down according to the rank, instead of including all the evacuation routes ER (Ef) and ER (Sg). How many are included in descending order of the degree of risk is set in advance by the system management policy, the watcher 102 and the like.

  FIG. 11 is an example of the danger information map generated by the map generation processing unit 138. Specifically, the evacuation place 104 where the child evacuates or the evacuation route to the rescuer 103 and the danger range for the place where the crime or disaster occurred are shown.

  Next, information distribution processing will be described. In the information distribution process, after the map generation processing unit 138 generates the risk information map DM, the information distribution processing unit 142 of the information distribution system 113 performs the at least one risk DC and the risk information map DM of the current watching target person 101. Is sent to the monitoring target person 101, the monitoring person 102, the rescuer 103, the terminals 117 to 120 of the evacuable area 104, and other contact information (such as e-mail or FAX) as necessary. To do.

  The terminals 117 to 120 that have received the alarm information DI from the information distribution processing unit 142 of the information distribution system 113 are stored in the first storage areas 151, 159, 166, and 172 of the storage units 150, 158, 165, and 171 of each terminal. Stores alarm information DI. At this time, if the watching target person 101 has not started the evacuation action, the evacuation action support process is performed at any time without displaying the danger information map DM on the information display units 149, 157, 164, and 170 of each terminal. It is good to display the symbol or character string which shows that it can do. When the watching target person 101 starts the evacuation action, the danger information map DM is automatically displayed on the information display unit 149 or 170 of the terminal 117 or 120 of the rescuer 103 selected as the evacuation destination or the evacuable place 104. Urges the rescuer 103 or the evacuable place 104 to be wary.

  Finally, the evacuation action support process will be described. First, a process performed when the terminal 118 of the person 101 to be watched for the evacuation action support process receives the alarm information DI will be described.

  FIG. 12 is a time chart showing a processing procedure at the time of reception.

  When the communication unit 155 of the terminal 118 possessed by the watching target person 101 receives the alarm information DI (600), the communication unit 155 first notifies the terminal control unit 156 that the alarm information DI has arrived (601). Then, the terminal control unit 156 stores the alarm information DI in the first storage area 159 of the storage unit 158 (602, 603).

  At this time, the alarm information DI is not displayed on the information display unit 157, but the operation button is operated to notify that the evacuation action support using the danger information map DM included in DI can be performed. A symbol or character string is displayed (604, 605).

  Next, processing for supporting evacuation behavior using the danger information map DM will be described.

  FIG. 13 is a time chart showing a procedure for evacuation action support.

  When the watching target person 101 feels some danger and operates the operation button 160 of the terminal 118 (606, 607), the terminal control unit 156 notifies the evacuation behavior support processing unit 154 of the start of the evacuation behavior support processing (608). ).

  The evacuation action support processing unit 154 first displays the danger information map DM included in the alarm information DI stored in the first storage area 159 of the storage unit 158 on the information display unit 157 (609 to 612). Next, the evacuation action support processing unit 154 selects an evacuation route having a higher rank among several evacuation routes included in the danger information map DM (613). The evacuation action support processing unit 154 starts evacuation route guidance for the selected evacuation route (614). Specifically, the evacuation action support processing unit 154 determines the direction in which the watching target person 101 should travel based on the current position of the watching target person 101 and the selected evacuation route, and performs evacuation route guidance (615). The evacuation route guidance method is a method that is easy to understand for the watching target person 101, such as guiding the direction of the watching target person 101 by voice or displaying the direction of the watching target person 101 on the information display unit 157. Any method may be used.

  Further, the evacuation route to be guided may be selected / changed according to the moving direction of the watching target person 101. For example, after the operation button is operated, when the watching target person 101 starts to travel on a path different from the high-order evacuation route, the evacuation route to be guided is newly selected in consideration of the moving direction and position of the watching target person 101. In addition, when the evacuation route guidance has already been performed and the evacuation route deviates from the guided evacuation route, the evacuation route to be guided is changed in consideration of the moving direction and position of the watching target person 101.

  After a certain period of time, the evacuation action support processing unit 154 determines the current time of the watching target person 101 by the position measurement processing unit 153 of the terminal 118 possessed by the watching target person 101 and the position inquiry processing unit 145 of the terminal position measuring system 116. Get position (616-620). Specifically, the evacuation action support processing unit 154 requests the position measurement processing unit 153 for the position of the watching target person 101 (616). The position measurement unit 153 inquires of the position inquiry processing unit 145 about the requested position of the watching target person 101 (617). The position inquiry processing unit 145 measures the position of the watching target person 101 (618), and returns the measured position of the watching target person 101 to the position measurement processing unit 153 (619). The position measurement processing unit 153 returns the position of the watching target received from the position inquiry processing unit 145 to the evacuation action support processing unit 154 (620).

  Next, when the position of the watching target person 101 coincides with the evacuation destination (the rescuer 103 or the evacuable place 104) of the evacuation route, the evacuation action support process is ended. If they do not match, the processes of 615 to 620 are repeated (621).

  Next, processing related to the terminal of the evacuation destination (the rescuer 103 or the evacuable place 104) when performing the evacuation action support processing will be described.

  FIG. 14 is a time chart showing the processing procedure of the terminal 117 of the rescuer 103 when the evacuation destination of the evacuation action support process is the rescuer 103. The same processing is performed when the evacuation destination is the evacuable place 104.

  The evacuation action support processing unit 154 of the terminal 118 of the person to be watched 101 selects the evacuation route (613), and then the terminal 117 of the rescuer 103 who is the evacuation destination of the evacuation route or the terminal 120 of the evacuable place 104. The information indicating that the evacuation destination has been selected and the same alarm information DI transmitted to the person to be watched 101, or the number that can uniquely identify the information indicating that the evacuation destination has been selected and the alarm information DI are transmitted. The communication unit 155 is instructed (700, 701).

  The communication unit 147 of the terminal 117 of the rescuer 103 who received the information or the communication unit 168 of the terminal 120 of the evacuable place 104 notifies the terminal control unit 148 or 169 that it has been selected as the evacuation destination (702). The terminal control unit 148 or 169 displays characters, images, etc. that can be seen as being selected as the evacuation destination on the information display unit 149 or 170, and further receives the received alarm information DI or the alarm information of the first storage area The danger information map DM included in the DI is displayed on the information display unit 149 or 170 (703, 704).

  Thereafter, the evacuation action support processing unit 154 measures the position of the watching target person 101 by the position reference processing unit 145 of the terminal position measuring system 116 and the position measurement processing unit 153 of the terminal 118 of the watching target person 101 (705 to 709). . Specifically, the evacuation action support processing unit 154 requests the position measurement processing unit 153 of the terminal position measurement system 116 for the position of the watching target person 101 (705). The position measuring unit 153 inquires the position inquiry processing unit 145 about the requested position of the person 101 to be watched (706). The position inquiry processing unit 145 measures the position of the watching target person 101 (707), and returns the measured position of the watching target person 101 to the position measurement processing unit 153 (708). The position measurement processing unit 153 returns the position of the watching target received from the position inquiry processing unit 145 to the evacuation action support processing unit 154 (709).

  Next, the evacuation action support processing unit 154 transmits the measured position information of the watching target person 101 to the map generation processing unit 138 of the map generation system 112. The map generation processing unit 138 generates a map that includes the transmitted position information of the watching target person 101. The generated map is transmitted to the terminal 117 of the evacuation destination rescuer 103 or the terminal 120 of the evacuable place 104 and displayed on the information display unit 149 or 170 (710 to 716). Specifically, the evacuation action support processing unit 154 transmits the position of the watching target person 101 to the communication unit 155 (710). The communication unit 155 transmits the position of the watching target person 101 to the map generation processing unit 138 of the map generation system 112 (711). The map generation processing unit 138 generates a map based on the received position of the watching target person 101 (712). The map generation processing unit 138 transmits the generated map to the communication unit 147 of the rescuer 103 (713). The communication unit 147 confirms that the map has been received by the terminal control unit 148 (714). Next, the terminal control unit 148 requests the information display unit 149 to display a map (715). And the information display part 149 displays a map (716) The process of 705-716 is periodically performed by the space | interval of a fixed time.

  In addition, a message is displayed so that the state of the evacuation behavior of the watching target person 101 can be understood. For example, when the watching target person 101 approaches the vicinity of the rescuer 103 or the evacuable place 104, a symbol or a character string for requesting protection of the watching target person 101 may be displayed on the information display unit 149 or 170. . In addition, when the evacuation destination is changed, the fact may be displayed on the information display unit 149 or 170.

  In addition, when the terminal 117 or 120 is equipped with a speaker or a vibrator (vibration function), you may notify them to the rescuer 103 and the evacuable place 104 in combination.

  The information transmitted by each terminal of the watching target person 101, the rescuer 103, and the evacuable place 104 in the above evacuation action support process can also be received by the terminal 119 of the watching person 102.

  The danger information map DM stored in the first storage area of each terminal is deleted from the first storage area after a certain period of time or when a certain condition, for example, a condition that a new danger information map DM is received is satisfied. Or move to a portion other than the first storage area of the storage unit.

  As described above, according to the first embodiment of the present invention, the risk level and risk range of the crime or disaster that has occurred are automatically calculated and set, and based on the current position or time of the person being watched over, etc. Calculate the risk. In addition, an evacuation route to be taken by the person being watched over should be generated based on the risk level of the person being watched over and the occurrence of crimes or disasters around the person being watched over, and danger map information including the generated evacuation route can be distributed it can. Moreover, when the watching target person feels danger, the evacuation action support can be started immediately.

Second Embodiment
A second embodiment of the present invention will be described.

  In the first embodiment of the present invention, it is possible to avoid a dangerous state when the watching target person 101 evacuates. On the other hand, in the second embodiment of the present invention, in addition to evacuation of the watching target person 101, an example in which the rescuer 103 heads for the watching target person 101 is shown. Hereinafter, the process performed by the computer system when the rescuer 103 heads for rescue of the watching target person 101 is referred to as a rescue action support process.

  FIG. 15 shows the configuration of the terminal 117 possessed by the rescuer 103 in the second embodiment of the present invention. The difference from the terminal 117 in FIG. 1 is that a rescuer support processing unit 174 that performs a process for assisting the rescuer 103 to watch over the target person 101 is provided. Other parts of the terminal 117 and other computer systems are the same as those in FIG.

  First, a process performed when the terminal 117 of the rescuer 103 in the rescue action support process receives the warning information DI will be described.

  FIG. 16 is a time chart showing a procedure of processing when alarm information DI is received.

  When the communication unit 147 of the terminal 117 possessed by the rescuer 103 receives the alarm information DI including the danger information map (800), first, the communication unit 147 indicates that the terminal control unit 148 has received the alarm information DI. Notification is made (801). Then, the terminal control unit 148 stores the alarm information DI in the first storage area 151 of the storage unit 150 (802, 803).

  At this time, the information display unit 149 does not display the alarm information DI, but by operating the operation button 160, a symbol or character string for notifying that the danger information map DM included in the alarm information DI can be displayed. Is displayed (804, 805).

  Next, a process for providing relief action support using the danger information map DM will be described.

  FIG. 17 is a time chart showing the procedure of the rescue action support process.

  When the person 101 to be watched feels some danger and operates the operation button 160 of the terminal 118 (806, 807), the terminal control unit 156 displays the rescuer 103 included in the danger information map DM of the stored alarm information DI. Terminal 118 is requested to start the rescue action support process (808).

  The rescue action support processing unit 174 displays the danger information map DM included in the alarm information DI stored in the first storage area 151 of the storage unit 150 on the information display unit 149 (809 to 812). Specifically, the rescue action support processing unit 174 requests the information display unit 157 to display the danger information map DM (809). The information display unit 149 requests the first storage area 151 to read out the danger information map DM to be displayed (810). The first storage area 151 returns the stored danger information map DM to the information display section 149. (811) Then, the information display unit 159 displays the danger information map DM (812). Next, the rescue action support processing unit 174 generates the evacuation route generation process between the watching target person 101 and the rescuer 103. The rescue route guidance is started using the evacuated route (813). Specifically, based on the current position of the rescuer 103 and the selected evacuation route, the direction in which the rescuer 103 should proceed is determined, and relief route guidance is performed (814). The evacuation route guidance method may be any method as long as it is easy to understand for the rescuer 103, for example, by voice or displaying the direction to the information display unit 149.

  Moreover, the evacuation route to guide may be newly produced | generated by the position of the watching target person 101 and the moving direction of the rescuer 103. For example, when the position of the watching target person 101 changes after the operation of the operation button, or when the rescuer 103 starts to follow a path different from the route, the position and moving direction of the watching target person 101 or the rescuer 103 are considered. The evacuation route to be guided is generated again.

  After a certain period of time, the rescue action support processing unit 174 includes the position measurement processing unit 153 of the terminal 118 possessed by the person to be watched 101, the position measurement processing unit 146 of the terminal 117 possessed by the rescuer 103, and the terminal position measurement system 116. The position of the watch target person 101 and the rescuer 103 are obtained based on the current position inquiry processing unit 145 (815 to 824). Specifically, specifically, the relief action support processing unit 174 requests the position measurement processing unit 153 of the terminal position measurement system 116 for the position of the watching target person 101 (815). The position measurement unit 153 inquires of the position inquiry processing unit 145 about the requested position of the watching target person 101 (816). The position inquiry processing unit 145 measures the position of the watching target person 101 (817), and returns the measured position of the watching target person 101 to the position measurement processing unit 153 (818). The position measurement processing unit 153 returns the position of the watching target person 101 received from the position inquiry processing unit 145 to the rescue action support processing unit 174 (819). Next, the rescue action support processing unit 174 requests the position of the rescuer 103 from the position measurement processing unit 153 of the terminal position measurement system 116 (820). The position measurement unit 153 inquires of the position inquiry processing unit 146 about the position of the requested rescuer 103 (821). The position inquiry processing unit 146 measures the position of the rescuer 103 (822), and returns the measured position of the rescuer 103 to the position measurement processing unit 153 (823). The position measurement processing unit 153 returns the position of the rescuer 103 received from the position inquiry processing unit 145 to the rescue action support processing unit 174 (709). When the positions of the watching target person 101 and the rescuer 103 match, the rescue action support process is terminated. If they do not match, the processing of 814 to 824 is repeated (825).

  During the rescue action support process, the content of the rescue action of each rescuer 103 is displayed on each terminal of the watch target person 101, the watch performer 102, and the rescuer 103 and the evacuable place 104 included in the danger information map DM. The Specifically, the information distribution processing unit 142 of the information distribution system 113 distributes a map including the positions of the watching target person 101 and each rescuer 103 generated by the map generation processing unit 138 of the map generation system 112 to each terminal.

  As described above, according to the second embodiment, in addition to the evacuation behavior support for the watching target person, the relief action support is provided to the rescuer, so that the support target person can be quickly rescued.

<Third Embodiment>
A third embodiment of the present invention will be described below.

  In the first embodiment of the present invention, the risk level / risk range calculation process extracts a part P (Ia) indicating a place where a crime and a disaster have occurred from the crime / disaster information Ia, and P (Ia) is the center. Hazard range was set. However, if P (Ia) does not contain information that can specify the occurrence location in detail, the risk range is determined by setting a wide area as shown in FIG. On the other hand, the third embodiment of the present invention shows an example in which a detailed risk range is calculated by inquiring of an institution 122 such as a police or a private security company having detailed information on crime / disaster information.

  FIG. 18 is a block diagram of a computer system for carrying out the third embodiment. 1 is different from the computer system in that an engine 122 is provided. Although not shown in FIG. 18, the institution 122 includes a crime / disaster information DB and a risk / risk range calculation processing unit. The risk level / risk range DB of the institution 122 stores the detailed risk level and risk range assigned to the crime or disaster mode, occurrence time, occurrence location, and the like. Further, the risk / risk range calculation processing unit of the engine 122 calculates the risk level and the risk range. The parts other than the engine 122 are the same as the computer system of FIG.

  FIG. 19 is a time chart showing the procedure of the risk determination process according to the third embodiment of the present invention.

  First, in the risk level / risk range calculation process, the risk range is calculated by the same method as in the first embodiment of the present invention. Further, in the danger determination process, crime / disaster information Ih including the current position PC of the watching target person 101 in the danger range is extracted. Next, the danger determination system 114 transmits the current position PC of the person 101 to be watched and the crime / disaster information Ih (h ≧ 1) including the PC in the danger range to the institution 122, and the person 101 to be watched by the detailed danger range. The crime / disaster information including the current position PC is requested (310).

  The risk level / risk range calculation processing unit of the institution 122 calculates a detailed risk range based on the detailed location of the crime or disaster included in the crime / disaster information Ih (311). Next, the crime / disaster information DB of the institution 122 extracts crime / disaster information Ih ′ (h ′ ≧ 1) including the current position PC of the person 101 to be watched within the calculated detailed risk range (312), The crime / disaster information Ih ′ is transmitted to the risk determination system 114 (313). Next, the risk determination processing unit 143 of the risk determination system 114 calculates the risk level DC of the person 101 to be watched based on the crime / disaster information Ih ′ received from the crime / lifetime information DB of the institution 122 (314). .

  Depending on the management policy of the institution 122, the crime / disaster information Ih ′ may not be transmitted. In this case, the risk level / risk range calculation method is transmitted to the engine 122 in advance, and the risk level / risk range calculation processing unit of the engine 122 calculates the risk level DC of the watching target person 101 based on Ih ′. The calculated risk degree DC is transmitted to the risk determination system 114.

  As described above, according to the third embodiment of the present invention, the detailed information of the crime / disaster information Ia is obtained by requesting the organization 122 that stores the detailed information of the crime / disaster information Ia to recalculate the risk range. The detailed risk level of the person being watched over can be calculated without disclosing personal information included.

  Although the best mode for carrying out the present invention has been described above, the watching method and system of the present invention are not limited to the above-described illustrated examples, and various methods are possible within the scope of the present invention. Of course, changes can be made.
