Description

  The present invention relates to a reporting point identification device and a reporting point identification method, and relates to an apparatus for quickly identifying a reporting point even when reporting from a reporting person whose position is difficult to identify when a fire or accident is encountered.

  When receiving a report of the occurrence of a fire or an accident, the fire department and the police need to know the exact location in order to issue a dispatch command. When the whistleblower recognizes the address of the point of occurrence, for example, as shown in FIG. 6, the town name is designated according to the contents of the notice (step 1, hereinafter abbreviated as ST1), and the number is designated (ST2). ) By designating the address and number (ST3), it is possible to specify the disaster spot on a map or the like (ST4) and to command dispatch.

  If the address is not known, as shown in FIG. 7, the inquirer is asked for the name of the resident's household head and nearby objects, and this is searched on a map or map data (ST11). Can be confirmed (ST12; Yes), since the disaster point can be specified (ST13), dispatch can be commanded. If the address corresponding to the report is not found (ST12; No), the reporter is asked again for other targets, and if there is information, this is searched on the map or map data (ST14). Is confirmed (ST15; Yes), and the disaster point is specified (ST13). If the address cannot be confirmed (ST15; No), the search is performed by another search method.

  Even when the address is unknown and there is no target, in the case of a notification through a public line, the point transmitted by the telephone company's call location inquiry system can be specified. That is, as shown in FIG. 8, a call origin place inquiry system is used (ST21), and if the address data is correct (ST22; Yes), the address location is searched (ST23). If the corresponding place is found (ST24; Yes), the location of the reporter, that is, the disaster point can be specified (ST25). If there is any error in the address data (ST22; No), or if the address is not incorrect but the corresponding address cannot be confirmed (ST24; No), the disaster location cannot be specified, so another search The method is performed (ST26).

  However, in the case of a report using a mobile phone, first, it is connected to a police station or a fire station set up in each area including the municipality where the report was sent, and a fire station or police that has jurisdiction over the municipality notified from here. This is the first time that the whistleblower will report the nature of the disaster and the location of the disaster. Since reports from mobile phones are sent without going through the public line, the above-mentioned calling location inquiry system cannot be used, so it is difficult to specify the location where the address is unknown or there is no target, It takes time to issue a command. Some mobile phones are equipped with a GPS (Global Positioning System) function and can display the current position, but the current situation is not necessarily equipped with a GPS function.

  Therefore, for example, there is a device provided with an apparatus as shown in FIG. 9 (see, for example, Patent Document 1). In this apparatus, the operator who has received the report inputs the name of the target (s) notified from the reporter and the upper limit distance between the targets set appropriately from the input unit 21. Based on this input, the map data search unit 23 of the CPU 22 searches the target data in the map database stored in the map data storage unit 26 for the name of each target and each position data (position on the map). The search result is temporarily stored in the RAM 27 together with the upper limit distance.

  Next, the distance calculation unit 24 calculates the distance between the target objects from the position data stored in the RAM 27, and the link detection unit 25 compares these distances with the upper limit distance and is close to the upper limit distance range. The comrades are linked and displayed on the map image of the display unit 28, thereby identifying the reporting point (close to the disaster occurrence point) from two nearby targets. The ROM 29 stores an operation program for the CPU 22.

  Further, the road number of the road is input from the input unit 21, the map data search unit 23 searches for the neighborhood region of the road with the specified route number from the road information in the map database of the map data storage unit 26, and the display unit In some cases, it is possible to specify the reporting point by displaying it on 28. However, in both cases, there is a problem that both the reporter and the operator need some intuition, and it takes time to specify the report point.

JP 2001-331491 A (page 3-5, FIG. 93)

  The present invention solves the problems described above, and even if the address where the disaster occurred is unknown in the report from the whistleblower, the whistleblower or operator has no intuition about the land around the disaster area. However, it is possible to quickly identify the reporting point by listening to information such as what the target is visible to the whistleblower and where the whistleblower is on the route from (first point) to where (second point). The purpose is to do so.

  In order to solve the above-mentioned problem, the present invention identifies the reporting point of the reporting party from the map data stored in the map database based on the reporting from the reporting party, and outputs the identified reporting point to the output unit. In the reporting point specifying device, the input unit that inputs information about the target obtained by the reporting party visually at the reporting point and the first and second points of the reporting party among the reporting contents, and the input A search unit for searching for the target from the map database based on the information on the target and the first and second points of the reporter, and a candidate site for the report point based on the search result of the search unit A reporting point specifying device that specifies and outputs the candidate site to the output unit is configured.

  In addition, a priority determination unit that prioritizes search results of the search unit is provided, and when there are a plurality of candidate sites as search results, the priority determination unit prioritizes candidate sites, and the output Configured to be output to the unit.

  Further, in the reporting point identification method for identifying the reporting point of the reporting party from the map data stored in the map database based on the report from the reporting reporter who is moving, the target obtained by the reporting party visually at the reporting point The reporting point specifying method is to specify the reporting point from the information about the object and the first point and the second point of the reporter.

  By using the above means, according to the reporting point identification device and the reporting point identification method according to the present invention, when the occurrence of a fire or an accident is reported, the reporter does not know the address of the place of occurrence. Even if the person is unfamiliar with the circumstances, the whistleblower can report by reporting the target information that can be seen from the whistleblower point and where the whistleblower is going from (first point) to where (second point). The received operator searches the map database for the route or area where the reporter is present, searches the reported target from the vicinity of the route, makes it a candidate location for the report point, and assumes that a disaster has occurred near this point. It issues a dispatch command and can respond quickly.

  In addition, when there are two or more searched targets, the priority order determination unit determines the priority order as a candidate place, so check whether or not it is a report place in order from a candidate place with a high possibility as a report place. Can do. Furthermore, waste such as issuing a dispatch command to the wrong point can be reduced, and prompt response can be made.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail as examples based on the attached drawings.

  FIG. 1 is a block diagram of a main part of an embodiment of a reporting point specifying device and a reporting point specifying method according to the present invention. 1 is information on a reported target and information on a route where a reporter exists, that is, a reporter. 2 is a map database, 3 is a search unit for searching for a target or a route from the map database based on information input from the input unit 1, and 4 is a searched target. A priority determination unit that prioritizes candidate sites when there are a plurality of objects, and 5 is an output unit that outputs a search result from the search unit 3 or a result determined by the priority determination unit 4, and a target object, An input screen for inputting the first point, the second point, and the like, and a display screen for displaying a map screen of candidate locations for notification points are provided. Reference numeral 6 denotes a control unit that controls the above-described units, and reference numeral 7 denotes a distance calculation unit 7 that calculates a distance between the target objects or a distance between the target object and the route.

  The input means to the input unit 1 can be selected as appropriate, and examples include keyboard input and voice input. Of course, it is only necessary to be able to input information for specifying the reporting point. Therefore, any input means that can achieve this function is not limited to these means.

  For example, the output screen of the candidate location of the reporting point of the output unit 5 may be as shown in FIG. When the output screen is broadly divided into a map output area 8 and an input information display area 9, and the search result from the search unit 3 becomes three places, the map output area 8 is changed to 8a, 8b, 8c, 8d. Divide into four. The first candidate site is output to 8a, the second candidate site to 8b, the third candidate site to 8c, and the list of these candidate sites to 8d. In the input information display area 9, information on the first and second points of the caller such as “FROM: Lake Ashinoko TO Mt. Fuji”, and the caller such as “XX elementary school convenience store △△” Outputs information about the target obtained visually from the point. Although FIG. 2 shows the map output area divided into four parts, it is possible to select how many parts the map output area is divided. For example, the map output area 8 is divided into two parts, The map display unit may be used as the candidate site list display region, and the selected candidate site may be output to the map display unit by selecting the candidate site to be specified from the candidate site list display region. Alternatively, the map display unit may be divided into four or more sections so that as many maps as possible are displayed. Further, in the present embodiment, the map output area 8 and the input information display area 9 are arranged vertically, but it is also possible to appropriately select whether the input information is not displayed even if it is left and right.

  The output unit 5 is not limited to the video display device having the display screen shown in FIG. 2, but may be an audio output device using a speaker or the like, or a combination thereof.

  Next, the flow from receiving a report to specifying the reporting point will be described.

  When witnesses of fires or accidents report using a mobile phone etc., the report is once connected to a police station or fire station set up in several municipalities including the district where the call was made. It is transferred to the fire department or police station that has jurisdiction over the municipality where it occurs. The fire department or police station operator who received the report confirms the address of the location where the accident occurred and issues a dispatch command.

  If you know the address of the location of the accident, etc., you can issue a dispatch order based on it, but if you do not know the location of the accident clearly, you need to identify the location of the accident from the information from the whistleblower. There is. Here, when specifying the point of occurrence, the reporter usually reports from the vicinity of the point of occurrence, so if the reporter's report point can be specified, the point of occurrence can also be specified. Therefore, in the present invention, the reporter's report point is specified from the information that the reporter can obtain from the report point, and the occurrence point is specified via the reporter's report point.

  First, the operator obtains from the whistleblower information regarding the target obtained by the whistleblower, such as the name of the shop that can be seen, the name of the school, or the river can be seen nearby, or there is a large bridge nearby. . Based on that, the operator selects and inputs all the information obtained from the reporter from the input unit 1 or information useful for specifying the reporter's report point.

  Further, the operator acquires information on the first point and the second point from the reporter. The information about the first and second points includes the final departure and destination points when the reporter is heading to a certain point, the points that have passed or passed through from the departure point to the destination point, etc. Applicable, for example, the location of the home, the name of the IC of the last highway, the name of the station where the train got off or is scheduled to get off, the name of the company, the store name, the name of the tourist spot, etc. The information regarding the first point and the second point is mainly used for determining the geographical search range of the target object and prioritizing the candidate sites for the reporting point. Based on that, the operator selects and inputs all the information obtained from the reporter from the input unit 1 or information useful for specifying the occurrence point of an accident or the like.

  The search unit 3 searches the map database 2 for a place corresponding to an occurrence point of an accident or the like using the input target, information on the first point and the second point. The searched report point is output to the output unit 5 described above, and displayed, for example, in the map output area 8 of the display screen. While viewing this screen, the operator confirms whether or not the report point displayed in a call or the like with the reporter matches the actual report point, and then specifies the report point of the reporter.

  When two or more disaster occurrence points are retrieved from the map database 2, the priority determination unit 4 prioritizes the disaster occurrence points, and these are first displayed in the map output area 8 on the display screen of the output unit 5. Candidate sites, second candidate sites, and third candidate sites are displayed, and the operator confirms which of the report points output during a call with the reporter matches the actual report point while viewing this screen. And identify the reporting point of the reporter.

  Next, the identification of reporting points according to the reporting content will be described together with specific criteria for prioritization.

  First, as shown in FIG. 3, a case where information on the first point A, the second point B, and the target C is obtained from the reporter will be described.

  The operator inputs the first point A and the second point B of the reporter from the input unit 1. In response to this input, the route normally used to go from the first point A to the second point B from the map database 2 by the search unit 3 via the control unit 6 (shortest route, route using a main road, etc.) A to B (indicated by bold lines in FIG. 3) are searched. Then, a geographical range E that is a range around routes A to B including the first point A and the second point B is specified. It is possible to determine how to take this geographical range E as appropriate. For example, when there are a plurality of routes from the first point A to the second point B, the reporter can take any route. Since it is unknown whether it exists, it is conceivable to set to include all these routes. In addition, if the distance from the first point A to the second point B is long (such as when the whistleblower is heading for sightseeing, etc.), the whistleblower will not have detailed land insights. The shape may be determined along a road or a highway. Thereafter, in the geographical range E, when the reported target is only C1 and the operator is only C1, the operator inputs the target C1 from the input unit 1. The search unit 3 searches whether or not the target C1 exists within the range of the geographical range E. If the target C1 exists, the map data of the surrounding area where the target C1 exists is read from the map database 2. And displayed in the map output area 8.

  As shown in FIG. 3, when three targets C1, C2, and C3 are searched within the geographical range E for a target that matches the information about the target notified from the reporter, the distance calculation of the control unit 6 is performed. The distances L1, L2, and L3 between the routes A to B and the targets C1, C2, and C3 are calculated by the unit. Since it is considered that the one near the route where the whistleblower is present is seen from the whistleblower, the priority determination unit 4 determines that the first candidate site of the reporting point is E3 including the target C3 in order from the route A to B. The region and the second candidate site are the region E2 including the target C2, and the third candidate site is the region E1 including the target C1, and these regions are output to the map output region 8 shown in FIG. At the time of output, the map output area is divided into four, the areas E3, E2, and E1 are displayed in 8a, 8b, and 8c, respectively, and a list of candidate sites is displayed in 8d. In the candidate place list, information such as an address is displayed for each target. Here, for each area displayed in the map output area 8, the operator draws more information from the reporter while confirming the map displayed there, and specifies the final report point. When confirming the reporting point, the operator can extract the information in order from the higher priority area, thereby shortening the time until the reporting point is specified.

  In the present embodiment, the geographical range E for searching for the target is determined in advance from the first point and the second point, but the first point A to the second point B are determined without setting the geographical range E. Routes (usually the shortest route, route using a main road, etc.) A to B that are normally used to go to the destination are determined, the target in the vicinity is searched, the distance between the route A to B and the target is calculated, and priority is given You may rank.

  Next, a case where information on the first point A, the second point B, and the targets D and E is obtained from the reporter will be described.

  From the information about the first point A and the second point B obtained from the reporter, a geographical range E, which is a range for searching for the route and target of AB, is determined. When there are one target D and E near each of the routes A to B, a map around the target is displayed in the map output area 8 and the reporting point is specified based on the map. In addition, when there are a plurality of targets D, E in the geographical range E, for example, when there are two each of the targets, as shown in FIG. The positions of the intermediate points F1, F2, F3, F4 of E and D ', D and E', and E 'and D', and the distances from these intermediate points F1, F2, F3, and F4 to the routes A to B Since it is considered that the point close to the route where the reporter is present is the reporting point, the priority determination unit 4 gives priority to the candidate sites of the reporting point in the order of the distance from the route A to B to each intermediate point. Determine the ranking. That is, the first candidate site is the F3 region, the second candidate site is the F4 region, the third candidate site is the F2 region, the fourth candidate site is the F1 region, etc. The map data of these areas is read from the map database 2 and displayed in the map output area 8 of the display screen. Using this, the operator identifies the final reporting point.

  In addition, when assigning priorities, the factors such as the height of the building are taken into consideration in addition to the distance factors as described above, whether or not they are in a positional relationship that can be visually observed from the routes A to B, etc. May be.

  Next, a case where the information on the first point A, the second point B, and the targets D and E is obtained from the reporter and the report point is searched without defining the routes A to B will be described.

  First, a certain geographical range E including the first point A and the second point B is determined from the information about the first point A and the second point B obtained from the reporter. After the geographical range E is determined, a target that exists in the geographical range E and matches the target D from the reporter and information related to E is searched. If the target corresponding to each of the targets D and E can be searched one by one, the reporter is in a position where the two targets can be seen simultaneously from the report point. It is presumed that the object exists in the middle of the object, and a map around the intermediate point is displayed in the map output area 8, and the final confirmation of the reporting point is performed based on the map.

  Next, in the case where a plurality of targets M1 and M2 are included in the geographical range E, here, a case where two targets are included respectively will be described. In this case, as shown in FIG. 5, the distance calculation unit causes the distance L1 between the targets M1 and M2, the distance L2 between the targets M1 and M2 ′, the distance L3 between the targets M1 ′ and M2, The distance L4 between the targets M1 'and M2' is calculated, and the reporter is viewing both of the targets at the same time from the reporting point. Since the priority order determination unit 4 arranges the distances between the targets in the order of L3, L1, L2, L4, the first candidate site for the reporting point is the E6 region, The second candidate site is determined as the E4 region, the third candidate site is the E5 region, the fourth candidate site is determined as the E7 region, and the like is displayed in the candidate site list column of the display screen, and the map data of these regions is displayed. Read from the map database 2 and display on the display screen.

  At this time, even if the distance between the targets is short, there are circumstances where two targets cannot be seen at the same time, such as a high-rise building between them, and the location of the high-rise building, etc. When the information is stored in the map database 2, the report points may be prioritized in consideration of such individual circumstances.

It is a principal part block diagram which shows the Example of the report point specific device by this invention and the report point specific method.
