  Subsequently, the location information notification server 120 determines whether the table creation unit 124 has created the terminal individual table 134 corresponding to the mobile terminal 110 that is the transmission source of the location information (step S1003). When the corresponding terminal individual table 134 is not created in step S1003, the table creation unit 124 creates the terminal individual table 134 of the mobile terminal 110 (step S1004). More specifically, the table creation unit 124 stores the start point and end point of the area specified in step S1002 in the terminal individual table 134 and the time when the position information is received in step S1001, and ends the process.

  When the corresponding terminal individual table 134 has already been created in step S1003, the direction speed calculation unit 126 compares the position information received in step S1001 with the position information received last time, and determines the traveling direction of the mobile terminal 110. The speed is calculated (step S1005). Details of the processing of the direction velocity calculation unit 126 of this embodiment will be described later.

  Subsequently, the location information notification server 120 updates the terminal individual table 134 by the table updating unit 125 (step S1006), and ends the process. Specifically, the table updating unit 125 sets the start point and end point of the area specified in step S1002, the traveling direction and speed of the mobile terminal 110 calculated in step S1005, and the time when the position information is received in step S1001 for each terminal. The data is stored in the table 134 and the process is terminated.

  Next, processing of the area search unit 122 and the area specifying unit 123 of this embodiment will be described with reference to FIG. FIG. 11 is a flowchart for explaining processing of the area search unit and the area specifying unit. FIG. 11 shows processing of the area search unit 122 and the area specifying unit 123 in step S1002 of FIG.

Note that the position information used in step S1101 is both latitude and longitude.

  If position information is included in the area of the area database 131 in step S1101, the area specifying unit 123 specifies an area including the position information (latitude and longitude) from the area database 131, and sets the start point and end point of the area. Obtain (step S1102).

  If the position information is not within the area defined in the area database 131 in step S1101, the area search unit 122 determines whether the position information is within the area defined in the correction area database 132 (step S1101). S1103). If position information is included in the area of the correction area database 132 in step S1103, the area specifying unit 123 proceeds to step S1102, and acquires the start point and end point of the corresponding area from the correction area database 132.

  If the position information is not within the area defined in the correction area database 132 in step S1103, the area search unit 122 determines whether the longitude of the position information is within the area defined in the area database 131 ( Step S1104). When the longitude of the position information is included in the area of the area database 131 in step S1104, the area specifying unit 123 proceeds to step S1102 and acquires the start point and the end point of the area including the longitude of the position information from the area database 131. . In addition, since it is possible to search for a plurality of areas based on only the longitude, the search target may be within a predetermined distance from the position information. When a plurality of searches are performed, the closest to the position information is possible. It may be an area.

  When the longitude of the position information is not included in the area of the area database 131 in step S1104, the area search unit 122 determines whether the latitude of the position information is within the area defined in the area database 131 ( Step S1105). When the latitude of the position information is included in the area of the area database 131 in step S1105, the area specifying unit 123 proceeds to step S1102 and acquires the start point and the end point of the area including the latitude of the position information from the area database 131. . In addition, since it is possible to search for a plurality of areas when judging only by the latitude, the search target may be within a predetermined distance from the position information. When a plurality of searches are performed, the closest to the position information is possible. It may be an area.

  If the latitude of the position information is not included in the area of the area database 131 in step S1105, the position information notification server 120 performs error processing in the acquisition of position information (step S1106). Specifically, for example, the position information may be received from the mobile terminal 110 again.

  As described above, in this embodiment, even when the position information received from the mobile terminal 110 does not exist in the area defined in the area database 131, the area including the position information received using the correction area database 132 is specified. can do. Therefore, in the present embodiment, the mobile terminal 110 can be specified even when the position information is out of the road D due to an error in the GPS function of the mobile terminal 110, for example.

  Hereinafter, with reference to FIG. 12 to FIG. 14, the processing of the area searching unit 122 and the area specifying unit 123 of the present embodiment will be specifically described.

  FIG. 12 is a first diagram illustrating the processing of the area search unit and the area specifying unit. FIG. 12A shows a point where the mobile terminal 110 transmits the position information to the position information notification server 120, and FIG. 12B shows a result of searching the area database 131 by the position information. .

  In FIG. 12, a point Pa where the mobile terminal 110 transmits the position information to the position information notification server 120 is a longitude 137.0162 and a latitude 36.5006. The position information of the point Pa is included in a range defined in the area R6 in the area database 131. Therefore, the point Pa is included in the area R6.

  Therefore, the area specifying unit 123 specifies the area R6 as an area including the position information. When the area is specified, the table updating unit 125 acquires the start point and end point of the area R6 from the area database 131 and stores them in the terminal individual table 134 together with the time when the position information is acquired.

  Here, calculation of the moving direction and moving speed of the mobile terminal 110 in the direction speed calculating unit 126 of the present embodiment will be described.

  In FIG. 12B, consider a case where the position information of the point Pb is received from the mobile terminal 110 five seconds before the position information of the point Pa is received.

  The position information of the point Pb is included in a range defined in the area R3 in the area database 131. Therefore, the point Pb is included in the area R3. Therefore, the mobile terminal 110 has moved from the area R3 toward the area R6.

  The direction speed calculation unit 126 of the present embodiment obtains the distance from the point Pb to the point Pa from the position information of the point Pb and the position information of the point Pa, and from the time it takes to move from the point Pb to the point Pa, The speed of the terminal 110 is calculated.

  In addition, the direction speed calculation unit 126 according to the present embodiment calculates the moving direction of the mobile terminal 110 based on the change of the start point in the terminal individual table 134.

  For example, when the position information notification server 120 receives the position information of the point Pb from the mobile terminal 110, the start point of the terminal individual table 134 is 100.7 and the end point is 101.1 (see FIG. 8). When the position information notification server 120 receives the position information of the point Pa from the mobile terminal 110, the start point of the terminal individual table 134 is 102.2 and the end point is 102.7.

  At this time, the starting point changes from 100.7 to 102.2. In this embodiment, the moving direction when the starting point increases in this way is determined as the upward direction, and the moving direction when the starting point decreases is determined as the downward direction. That is, in the present embodiment, when the mobile terminal 110 is moving in a direction in which the distance from the starting point t0 to one end closer to the starting point t0 of the area becomes longer, the moving direction of the mobile terminal 110 is determined as the upward direction. . Further, in this embodiment, when the mobile terminal 110 is moving in a direction in which the distance from the starting point t0 to one end closer to the area starting point t0 is shorter, the moving direction of the mobile terminal 110 is determined to be the downward direction. .

  Therefore, the direction velocity calculation unit 126 of this embodiment determines that the moving direction is the upward direction when the mobile terminal 110 moves from the point Pb to the point Pa in FIG.

  FIG. 13 is a second diagram illustrating the processing of the area search unit and the area specifying unit. FIG. 13 illustrates a case where the correction area database 132 is used. FIG. 13A shows a point where the mobile terminal 110 transmits the position information to the position information notification server 120, and FIG. 13B shows a result of searching the correction area database 132 using the position information. It is.

  In FIG. 13, the point Pc indicated by the position information transmitted by the mobile terminal 110 is a point outside the area defined in the area database 131 as shown in FIG. Therefore, the position information indicating the point Pc does not exist in the area defined in the area database 131.

  Therefore, the area search unit 122 according to the present embodiment searches the correction area database 132 with the position information of the point Pc. The longitude of the position information indicating the point Pc is 137.0160, and the latitude is 36.5004. Therefore, it can be seen that the position information indicating the point Pc is included in the area R2 ′ defined in the correction area database 132.

  Therefore, the area specifying unit 123 of the present embodiment acquires the start point 101.7 and the end point 103.7 of the corresponding area R2 ′ in the correction area database 132 and stores them in the terminal individual table 134.

  FIG. 14 is a third diagram for explaining the processing of the area search unit and the area specifying unit. FIG. 14 illustrates a case where the area database 131 is searched for either longitude or latitude in the position information. FIG. 14A is a diagram illustrating a case where the search is performed using only the longitude of the position information, and FIG. 14B is a diagram illustrating a case where the search is performed using only the latitude of the position information.

  For example, when the position information indicating the point Pc is not within the area of the correction area database 132, the area search unit 122 according to the present embodiment searches the area database 131 only with the longitude of the position information indicating the point Pc.

  In the case of FIG. 14A, the longitude of the point Pc is 137.0160. This longitude is included in a range that defines the area R6 in the area database 131. Therefore, the area specifying unit 123 specifies the area R6 as an area including the point Pc. When the area is specified, the table updating unit 125 acquires the start point and the end point of the area R6 from the area database 131 and stores them in the terminal individual table 134.

  When the area including the longitude of the point Pc does not exist in the area database 131, the area search unit 122 according to the present embodiment searches the area database 131 only with the latitude of the position information indicating the point Pc.

  In the case of FIG. 14B, the latitude of the point Pc is 36.5004. This latitude is included in a range that defines the area R4 in the area database 131. Therefore, the area specifying unit 123 specifies the area R4 as an area including the point Pc. When the area is specified, the table updating unit 125 acquires the start point and the end point of the area R4 from the area database 131 and stores them in the terminal individual table 134.

  Next, processing of the emergency telephone number acquisition unit 127 and the notification unit 128 of this embodiment will be described with reference to FIG. FIG. 15 is a second flowchart for explaining the operation of the location information notification server.

  The emergency telephone number acquisition unit 127 of the present embodiment determines whether there are a plurality of terminal individual tables 134 stored in the storage area 130 (step S1501). If there are not a plurality of terminal individual tables 134 stored in the storage area 130 in step S1501, the emergency telephone number acquisition unit 127 refers to the terminal individual table 134 to determine an area where an event occurs, (step S1502). It progresses to step S1505 mentioned later. Details of how to determine the area where the event occurs will be described later.

  When there are a plurality of terminal individual tables 134 stored in the storage area in step S1501, the emergency telephone number acquisition unit 127 determines an area where an event occurs for each terminal individual table 134 (step S1503). Subsequently, the emergency telephone number acquisition unit 127 determines the area where the number of times of occurrence as the event occurrence site is highest for each terminal individual table 134 in step S1503 as the event occurrence site (step S1504).

  Subsequently, the emergency telephone number acquisition unit 127 refers to the number correspondence database 133 and acquires the emergency telephone number of the emergency telephone 201 corresponding to the area determined as the event occurrence site (step S1505). More specifically, the emergency telephone number acquisition unit 127 acquires the start point, the end point, and the moving direction of the area determined as the event occurrence site from the terminal individual table 134, and the emergency correspondence corresponding to the area where these match in the number correspondence database 133. Get a phone number.

  Subsequently, the notification unit 128 notifies the reception desk 211 of the emergency telephone number acquired in step S1505 via the emergency telephone switch 210 (step S1506).

  Hereinafter, a method of determining an area that is an event occurrence site will be described with reference to FIGS.

  FIG. 16 is a first flowchart illustrating a process for determining an area where an event occurs. FIG. 16 shows details of the processing in step S1502 or step S1503 in FIG.

  The emergency telephone number acquisition unit 127 according to the present embodiment determines whether there is an area where the moving speed is equal to or less than a predetermined threshold set in the terminal individual table 134, for example (step S161).

  If there is no area where the moving speed is equal to or less than the threshold value in step S161, the emergency telephone number acquisition unit 127 stands by until the corresponding area appears.

  If there is an area where the moving speed is equal to or lower than the threshold value in step S161, the emergency telephone number acquisition unit 127 extracts an area before the moving speed becomes equal to or lower than the threshold value before the moving speed becomes equal to or lower than the threshold value (step S162). . Subsequently, the emergency telephone number acquisition unit 127 determines an area where an event occurs in accordance with a predetermined condition from the extracted area (step S163).

  In the present embodiment, for example, the predetermined threshold may be set to about 1 km / h, and the case where the moving speed is equal to or lower than the predetermined threshold may be determined as the state where the mobile terminal 110 is stopped. Hereinafter, the process of FIG. 16 will be described more specifically.

  FIG. 17 is a first diagram for explaining how to determine an area where an event occurs.

  FIG. 17 shows how to determine the event occurrence site when the mobile terminal 110 that has transmitted the position information stops moving after transmitting the position information. That is, FIG. 17 shows a case where the owner of the mobile terminal 110 stops moving after making a report to the control room. Specifically, for example, when the owner of the mobile terminal 110 riding in a vehicle traveling on the road D witnesses the occurrence of the event and notifies the control room, the vehicle stops traveling. .

  In the example of FIG. 17, in the terminal individual table 134, each of the point Pd indicated by the position information received at time T1, the point Pe indicated by the position information received at time T2, and the point Pf indicated by the position information received at time T3. The included area is shown. Time T2 is a time several seconds after time T1, and time T3 is a time several seconds after time T2.

  The point Pd is included in the area R2 at the time T1, the point Pe is included in the area R6 at the time T2, and the point Pf is included in the area R6 at the time T3.

  In the example of FIG. 17, the position information indicating the point Pe and the position information indicating the point Pf are the same, and the mobile terminal 110 is not moving from time T2 to time T3.

  In this case, the mobile terminal 110 reports to the control room in the area R2 and changes in that it remains in the area R6. Therefore, it is assumed that the event occurrence site is in any area from area R2 to area R6.

  In this embodiment, the area located in the center is determined as the event occurrence site from the area including the position information received first from the mobile terminal 110 to the area including the point where the movement of the mobile terminal 110 stops. It was.

  Therefore, the emergency telephone number acquisition unit 127 of the present embodiment determines the area R4 located in the center among the areas R2 to R6 as the event occurrence site.

  For example, when there is no area located in the center from the area including the position information received first to the area including the point where the mobile terminal 110 stops moving, the emergency telephone number acquisition unit 127 stops moving, for example. An area close to the area including the point may be the event occurrence site.

  When the area where the event occurs is determined, the notification unit 128 notifies the reception desk 211 via the emergency exchange 210 of the emergency telephone number corresponding to the determined area.

  Next, with reference to FIG. 18, another process for determining an area where an event occurs is described. FIG. 18 is a second flowchart for explaining processing for determining an area where an event occurs.

  The emergency telephone number acquisition unit 127 of the present embodiment determines whether there is an area where the moving speed is decelerated by a predetermined threshold or more in the terminal individual table 134, for example (step S181). If there is no corresponding area in step S181, the emergency telephone number acquisition unit 127 stands by.

  If there is a corresponding area in step S181, the emergency telephone number acquisition unit 127 extracts the area immediately before the start of the deceleration of the moving speed (step S182), and determines the extracted area as the area where the event occurs. (Step S183).

  FIG. 19 is a second diagram for explaining how to determine an area where an event occurs.

  FIG. 19 shows how the event occurrence site is determined when the mobile terminal 110 that has transmitted the position information does not stop after the position information is transmitted and the movement speed is reduced. That is, FIG. 19 shows a case where the owner of the mobile terminal 110 decelerates after running a report to the control room.

  19, in the terminal individual table 134, areas including the point Pg indicated by the position information received at time T1 and the point Ph indicated by the position information received at time T2 are area R3 and area R6.

  The emergency telephone number acquisition unit 127 refers to the terminal individual table 134 and detects an area where the moving speed of the mobile terminal 110 is decelerated by a predetermined value or more. In the example of FIG. 19, for example, it is assumed that the moving speed of the mobile terminal 110 in the area R6 is decelerated by a predetermined value or more compared to the moving speed of the mobile terminal 110 in the area R3.

  In this case, it is conceivable that the owner of the portable terminal 110 decelerates the moving speed immediately after witnessing the event and makes a report.

  Therefore, the emergency telephone number acquisition unit 127 of the present embodiment determines the area immediately before the area where deceleration has started as the event occurrence site.

  In the example of FIG. 19, since the mobile terminal 110 starts to decelerate in the area R3, the emergency telephone number acquisition unit 127 determines the area R2 through which the mobile terminal 110 has passed immediately before the area R3 as the event occurrence site. .

  Then, the emergency telephone number acquisition unit 127 acquires the moving direction of the mobile terminal 110 from the terminal individual table 134, refers to the number correspondence database 133, and corresponds to the emergency telephone 201 on the side that matches the moving direction of the mobile terminal 110 in the area R2. Get an emergency phone number.

  The notification unit 128 notifies the reception desk 211 of this emergency telephone number via the emergency telephone exchange 210.

  When determining the event occurrence site, the emergency telephone number acquisition unit 127 according to the present embodiment determines, for example, whether or not the movement of the mobile terminal 110 has stopped. The site of occurrence may be determined. Moreover, the emergency telephone number acquisition part 127 of a present Example may determine the event occurrence site with the method demonstrated in FIG. 19, when the movement of the portable terminal 110 does not stop.

  In addition, when there are a plurality of individual terminal tables 134, the emergency telephone number acquisition unit 127 of this embodiment determines an area where an event occurs for each terminal individual table 134 by the method described with reference to FIGS. To do.

  For example, a case where the position information notification server 120 receives position information from three mobile terminals 110 will be described.

  In this case, the table creation unit 124 creates three terminal individual tables 134 corresponding to each mobile terminal 110. The emergency telephone number acquisition unit 127 determines an area to be an event occurrence site for each of the three terminal individual tables 134. At this time, for example, it is assumed that the area R3 is determined as the event occurrence site in the two terminal individual tables 134 and the area R4 is determined as the event occurrence site in the one terminal individual table 134. In this case, the emergency telephone number acquisition unit 127 determines the area R2 that is the event occurrence site in the most terminal individual tables 134 as the event occurrence site.

  In the present embodiment, when there are a plurality of individual terminal tables 134, the area that is the event occurrence site in the largest number of individual terminal tables 134 is determined as the event occurrence site. However, the present invention is not limited to this. For example, in the terminal individual table 134 corresponding to the mobile terminal 110 that first transmitted the position information, the emergency telephone number acquisition unit 127 of the present embodiment may determine the area determined as the event occurrence site as the event occurrence site. .

  In the emergency telephone system 200 of this embodiment, when the emergency telephone number of the emergency telephone 201 in the area determined at the event occurrence site is notified from the location information notification server 120, the reception desk 211 refers to the emergency telephone database 213. , You can get the corresponding location information from the emergency phone number.

  FIG. 20 is a diagram illustrating an example of an emergency telephone database.

  The emergency telephone database 213 of this embodiment has emergency telephone numbers, kiloposts, route names, and names as information items, and each item is associated with an emergency telephone number.

  Upon reception of the emergency telephone number, the reception desk 211 can notify the emergency response organization of information indicating the location of the event occurrence site such as the kilometer post and the route name corresponding to the emergency telephone number.

  As described above, in the present embodiment, for example, even when a passenger of a traveling vehicle reports the occurrence of an event to the control room from the mobile terminal 110 other than the emergency telephone 201, the passenger is based on the position information of the mobile terminal 110. Determine the area where the event will occur. Then, the emergency telephone number of the emergency telephone 201 in the determined area is notified to the emergency telephone system 200.

  That is, the location information notification server 120 of the present embodiment converts the location information of the mobile terminal 110 that has made the report into the emergency phone number of the emergency telephone 201 arranged in the vicinity of the event occurrence site, and the emergency telephone number is converted into the emergency telephone system. 200 can be notified. Therefore, even if the emergency telephone system 200 receives a report directly from the mobile terminal 110, the site where the event occurred can be identified using the existing system.

  In the present embodiment, the area of the predetermined range is defined so that the emergency telephone 201 is included in each area, but the present invention is not limited to this. In the present embodiment, for example, the emergency telephone 201 can be replaced with a target in place of the emergency telephone 201, and the same processing can be performed using the emergency telephone number as identification information assigned to the target.
