In this example, a case where the user moves on foot from work to home after an earthquake disaster has occurred and the aftershock has settled is handled.
FIG. 3 is a sequence diagram illustrating an operation example of the system 10. In the sequence shown in FIG. 3, in the mobile terminal 200, the control unit 204 executes various processes by controlling various components connected to the internal bus 210 in accordance with a program stored in advance. Further, in the server 100, the control unit 103 executes various processes by controlling components such as various databases connected to the internal bus 102 in accordance with a program stored in advance.

First, the user searches for the branch of the bank closest to the workplace and moves to the nearest branch. Here, the user acquires the disaster prevention guide map 20 arranged for distribution in the branch.
Next, in step S <b> 3 a, the mobile terminal 200 acquires the two-dimensional code 26 described in the disaster prevention guide map 20 distributed at the branch of the current location using the code acquisition unit 206 and stores it in the storage unit 203.
Next, in step S <b> 3 b, the mobile terminal 200 acquires URL information and branch identification information of the current location from the acquired two-dimensional code 26 using the control unit 204 and the storage unit 203.
Next, in step S3c, based on the URL information, the mobile terminal 200 connects to the server 100 using the transmission / reception unit 201 and transmits branch identification information of the current location.

Next, in step S <b> 3 d, the server 100 gives connection permission to the mobile terminal 200.
Next, in step S3e, the server 100 uses the branch identification information of the two-dimensional code 26 and the branch information database 105 to search for the branch name at the current location.
Next, in step S3f, the server 100 stores the branch name of the current location of the mobile terminal 200 in the history information database 106, and stores the telephone number or IP address of the mobile terminal 200, the time, and the like in the history information database 106. .
Next, the server 100 transmits the branch name of the searched current location to the mobile terminal 200 and requests the mobile terminal 200 to transmit destination information (step S3g).

  Next, in step S3h, the mobile terminal 200 displays the received branch name of the current location on the display unit 205. FIG. 4 shows a display screen 400 of the display unit 205 as an example. Here, in the current location column 401, the branch name “A branch” of the current location is displayed.

Next, in step S <b> 3 i, the mobile terminal 200 inputs destination information using the operation unit 202. In the example of FIG. 4, “K city L town M chome N”, which is the address of the home, is entered in the destination column 402. In this destination column 402, a home address can be set as a default value.
Alternatively, one or a plurality of destinations may be registered on the server in advance for each user, the corresponding registered destinations may be displayed in a list based on user authentication, and the destinations may be specified by selecting them.
Next, in step S <b> 3 j, the mobile terminal 200 transmits the destination information input using the transmission / reception unit 201 to the server 100.

  Here, in the example of FIG. 4, “shortest distance” is selected in the search method column 403 as the default value of the search condition for branch route information. In the search method column 403, for example, a condition for searching for branch route information may be selected in consideration of the safety level of the area.

Next, in step S3k, the server 100 searches for branch route information from the branch at the current location to the branch close to the destination using the branch identification information at the current location, the destination information, and the branch information database 105. Details of the branch route information search method will be described later.
Next, in step S31, the server 100 stores the searched branch route information in the history information database 106.
Next, in step S <b> 3 m, the server 100 transmits the searched branch route information to the mobile terminal 200.

Next, in step S <b> 3 n, the mobile terminal 200 receives the searched branch route information using the transmission / reception unit 201 and stores the branch route information in the storage unit 203. Thereafter, the portable terminal 200 can read the stored branch route information from the storage unit 203 and display it on the display unit 205 as necessary.
Next, in step S3o, the portable terminal 200 displays the received branch route information on the display unit 205. FIG. 5 shows a display screen 500 of the display unit 205 as an example. In the example of FIG. 5, branch route information from the A branch that is the current location 501 to the D branch 504 that is close to the home that is the destination 505 is displayed in the order of the B branch 502 and the C branch 503. .
Next, in step S3p, the mobile terminal 200 requests the server 100 for map information including the position of the branch A at the current location.

Next, in step S3q, the server 100 obtains map information including the location of the branch A at the current location and the location of the branch B adjacent in the branch route information, the map information database 104, the branch information database 105, the related base network, and the like. It is created using the information database 107.
Next, in step S <b> 3 r, the server 100 transmits the created map information to the mobile terminal 200.

  Next, in step S <b> 3 s, the mobile terminal 200 displays the received map information on the display unit 205 and stores this map information in the storage unit 203. Thereafter, the portable terminal 200 can read the stored map information from the storage unit 203 and display it on the display unit 205 as necessary.

  FIG. 6 shows a display screen 600 of the display unit 205 as an example. The display screen 600 displays map information that includes the branch A of the current location 601 at the center and includes the branch B 602 adjacent to the branch route information. The range displayed by the map information is preferably the same as the disaster prevention guide map 20 arranged for distribution in the branch A, but the map is combined with the size or the number of pixels of the display unit 205 of the mobile terminal 200. You may reduce the content of information rather than the information which the disaster prevention guide map 20 shown in FIG. 2 has. For example, the map information displayed on the display unit 205 of the mobile terminal 200 reduces the resolution of roads, railways, or rivers according to the specifications of the display unit 205, and displays only the evacuation site, emergency water supply base, and disaster base hospital. You may do it. In the example of FIG. 6, the position of the evacuation site 620 is displayed together with the road and the river.

  In order to move from the branch A of the current location 601 toward the destination, it is understood that the route 610 may be followed.

  Next, in step S3t, the mobile terminal 200 requests the server 100 for the entire map information of the branch route from the branch A at the current location to the branch D near the destination. In the example illustrated in FIG. 5, the mobile terminal 200 is executed by clicking the “display entire view” field 506. In addition, the process (S3t-S3w) which acquires the whole figure demonstrated below is a process which a user requests | requires suitably as needed, and is not a process which must be performed every time.

Next, in step S3u, the server 100 obtains the entire map information of the branch route from the A branch at the current location to the D branch close to the destination, the map information database 104, the branch information database 105, and the related base network information database. 107.
Next, in step S <b> 3 v, the server 100 transmits the created overall view information to the mobile terminal 200.

  Next, in step S <b> 3 w, the mobile terminal 200 displays the received overall view information on the display unit 205 and stores this overall view information in the storage unit 203. Thereafter, the portable terminal 200 can read the stored general view information from the storage unit 203 and display it on the display unit 205 as necessary.

  FIG. 7 shows a display screen 700 of the display unit 205 as an example. The display screen 700 displays branch route information from the A branch that is the current location 701 to the D branch 704 that is close to the home that is the destination 705 via the B branch 702 and the C branch 703 in this order. . In addition, an evacuation site 720 is displayed on the display screen 700 as in FIG.

The user moves to the next branch B according to the branch route information using the disaster prevention guide map 20 distributed at the branch A or the map information shown on the display screens 600 and 700 stored in the portable terminal 200. The user obtains the disaster prevention guide map 20 created so that the B branch is located at the center of the B branch, and connects to the server 100 by the portable terminal 200 using the two-dimensional code 26 described in the disaster prevention guide map. By doing so, the same map information as the display screen 600 or 700 can be obtained.
By repeating the above operation, the user can finally move to the home after moving to the D branch near the home which is the destination.

  When the communication state between the portable terminal 200 and the server 100 is good, the portable terminal 200 receives the branch route information from the server 100 at the first branch A, and then is listed in the branch route information. The map information including the locations of the B branch, the C branch, and the D branch may be requested to the server 100 collectively, and the map information transmitted from the server 100 may be received and stored in the storage unit 203.

Next, a method for retrieving branch route information of the server 100 in S3k will be described in detail below with reference to FIGS.
FIG. 8 is a flowchart illustrating an example of a method in which the server 100 searches for branch route information. In the flowchart of FIG. 8, in the server 100, the control unit 103 executes various processes by controlling components such as various databases connected to the internal bus 102 according to a program stored in advance.
First, in step S801, the server 100 uses the two-dimensional code branch identification information, the map information database 104, and the branch information database 105 to obtain the current branch position.

Next, in step S802, the server 100 uses the map information database 104 to obtain the shortest route from the current branch position to the destination. Here, the shortest route is a route having the shortest distance in the road route without considering the position of the branch. FIG. 9 shows the shortest path 910 in the map corresponding to FIG. The shortest route is the shortest route among the road routes from the branch A of the current location 901 to the home which is the destination 905.
Although the shortest route is obtained here, an optimal route including local disaster information such as traffic closure information may be obtained.

Next, in step S803, the server 100 extracts a branch located within a predetermined distance from the determined shortest route. The example of FIG. 9 shows the result of extracting a branch in an area 920 that is within a predetermined distance (for example, 2 km) in a direction perpendicular to the tangential direction of the shortest path 910. In the example of FIG. 9, there are a B branch 902, a C branch 903, and a D branch 904 in the area 920. In FIG. 9, an E branch 906, an F branch 907, a G branch 908, and an H branch 909 also exist. However, since these branches are outside the area 920, they are not extracted.
The predetermined distance may be appropriately changed depending on the distance between the shortest route and the branch.

Next, in step S804, the server 100 selects a branch route with the shortest route distance, and ends a series of processing. As a method of selecting a branch route, for example, the Dijkstra method can be used. Here, the branch route having the shortest route distance is obtained, but a branch route having an optimum route including local disaster information such as traffic closure information may be obtained.
In the example shown in FIG. 10, from the A branch that is the current location 901, the first proceeds to the B branch 902, the second proceeds to the C branch 903, and the third proceeds to the D branch 904 adjacent to the home that is the destination 905. Branch route is selected.
Here, a branch route that sequentially proceeds through all three branches in the area 920 is selected. For example, when there are three or more branches in the area 920, all the branches existing in the area are displayed. If the branch route distance around the branch is longer than the branch route distance excluding some branches, the branch route around all branches may not be selected.
In this way, the server 100 transmits the selected branch route as branch route information to the portable terminal 200 (see step S3m in FIG. 3).

  According to the system 10 described above, branch route information corresponding to each destination can be guided to people who move to the destination when evacuating in the event of a disaster. Specifically, the user having the mobile terminal 200 displays the location of the adjacent branch from which the next map information can be obtained together with the branch route information from the branch at the current location to the branch close to the destination at the nearest branch. Since map information is also obtained, by repeating this operation, it is possible to surely move to a branch near the destination, so that it is possible to finally reach the destination.

  Moreover, although the said embodiment demonstrated taking the case of an earthquake disaster as an example, it is effective to use this system 10 when performing the evacuation drill in preparation for such a disaster in advance.

  Further, the present system 10 can also provide branch route information for moving on foot, for example, to other operating transportation in the event of a disaster such as a disruption of transportation due to a railway accident. Specifically, by inputting a station name or the like of the operating transportation system in the destination column 402 of FIG. 4 and transmitting the destination information from the portable terminal 200 to the server 100, the server 100 has the branch of the current location. The mobile phone 200 is provided with branch route information from the mobile phone to the branch near the destination station.

  Next, the operation of the system when the mobile terminal 200 deviates from the branch route information will be described below based on the system shown as the first embodiment.

In this system 10, the server 100 has a history information database 106 that stores a branch history from which the mobile terminal 200 has acquired branch information, and the server 100 has the location of the mobile terminal 200 deviated from the branch route information. In this case, using the history information database 106 and the branch information database 105, branch information close to the traveling direction of the mobile terminal 200 is obtained, and the branch information is transmitted to the mobile terminal 200.
Other configurations are the same as those of the first embodiment described above.

  For example, in the above-described first embodiment, the user has moved based on the branch route information received by the mobile terminal 200, or moved based on the branch route information depending on the disaster situation. May not be possible.

  In such a case, the user moves to the branch of the bank close to the place where the closure is faced, and obtains the disaster prevention guide map 20 centered on the branch, and the 2D described in the disaster prevention guide map 20. The code 26 is acquired by using the code acquisition unit 206 of the portable terminal 200, is connected to the server 100, and receives the map information in which the branch is located at the center together with the branch route information.

  Although the user cannot move based on the branch route information transmitted from the server 100 for the purpose of closing the road, the bank described in the disaster prevention guide map 20 or the received map information and located at a position outside the branch route information. You can move to other branches.

  In this way, when the user moves to another branch of the bank located outside the branch route information, acquires a new two-dimensional code 26 at the branch, and connects to the server 100, The server 100 recognizes that the position of the mobile terminal 200 is out of the branch route information. The history information database 106 stores the branch route information of each connected mobile terminal 200 and the branch history from which the branch information has been acquired. Therefore, the server 100 does not match the mobile terminal 200 when the two do not match. It is determined that the position has deviated from the branch route information.

  Then, the server 100 uses the history information database 106 and the branch information database 105 to obtain branch information that is close to the traveling direction of the mobile terminal 200, and transmits the branch information to the mobile terminal 200.

Next, a method in which the server 100 obtains branch information that is close to the traveling direction of the mobile terminal 200 will be described below.
FIG. 11A shows an example in which one branch history is newly stored in the history information database 106 after the position of the mobile terminal 200 deviates from the branch route information.
The position of the branch A1 indicates the position of the branch newly stored in the history information database 106 after the position of the mobile terminal 200 deviates from the branch route information. In this case, for example, the server 100 uses the map information database 104 and the branch information database 105 to search for other branch information existing within the radius rkm centered on the branch A1, and the searched branch information is a mobile terminal. 200. The radius rkm can be a distance that a human can move within 30 minutes on foot, for example.
In the example of FIG. 11A, other branches B1, B2, and B3 exist within a radius rkm centering on the branch A1.

FIG. 11B shows an example in which there are three branch histories newly stored in the history information database 106 after the position of the mobile terminal 200 deviates from the branch route information.
In the example of FIG. 11B, the mobile terminal 200 moves to the branch A1 after deviating from the branch route information, and then moves to the branch A2, and then is located at the current branch A3.
As a first method, there is a method in which the server 100 obtains branch information that is close to the traveling direction of the mobile terminal 200 in the order of closest to the point-to-point vector of the latest history. Considering a straight line L from the position of the branch A2 to the position of the branch A3, the branch that is close to the traveling direction of the mobile terminal 200 is selected in order from the shortest distance from the straight line L (the length of the perpendicular to the straight line). Can do. Specifically, the order is B3, B4, B5, B2, B1.

As a second method, there is a method in which the server 100 obtains branch information that is close to the traveling direction of the mobile terminal 200 in the order from the combined vector of the movement vectors connecting all past branches. The direction of the sum of the vector from the branch A1 to the branch A2 and the vector from the branch A2 to the branch A3 is represented by the direction of the straight line M from the branch A1 to the branch A3. Branches that are close to the traveling direction of the mobile terminal 200 can be selected in the order from the shortest distance from the straight line M (the length of the perpendicular to the straight line). Specifically, the order is B2, B3, B1, B4, and B5.
Here, in the first and second methods, when there are two or more branches having the same length of the perpendicular to the straight line L or the straight line M, the one having a shorter distance from the branch A3 is selected.

  As a third method, a fan-shaped area with a radius rkm of 60 degrees on the left and right of the straight line L with the branch A3 as the center is considered. After selecting a branch included in this area, the distance from the straight line L ( There is a method of selecting branches that are close to the traveling direction of the mobile terminal 200 in the order of decreasing length (perpendicular to a straight line). The radius rkm can be a distance that a human can move within 30 minutes on foot, for example.

In this case, it is preferable that the mobile terminal 200 has an IC tag reader function. In this way, a mechanism capable of acquiring position information can be used as appropriate.

  In the above-described embodiment, the name of the home or the station is input as the destination. However, there is no particular limitation as long as the destination is a destination, and the destination is, for example, the name of an intersection that is a meeting place with a person. It may be. That is, it is preferable that the method and system of the present invention be utilized not only in a disaster but also in normal times.

  In addition, the server 100 may include a disaster information database or a traffic information database, and branch route information may be created and transmitted to the mobile terminal 200 while avoiding closed routes or avoiding congested routes.

  In the above-described embodiment, the branch information database 104 stores the location information of the head office and branch network of one bank. However, the branch information database 104 stores the locations of the head office and branch network of other banks. Information may also be stored. In this case, it is preferable that a disaster prevention guide map in which a two-dimensional code is written is placed for distribution at the head office and branch of another bank.

  In addition, an access point to the server 100 is installed in each branch, and it may be possible to connect to the server 100 without going through the mobile communication network 30 or the Internet network 20.

  Further, when the mobile terminal 200 approaches a predetermined distance (for example, within 5 km) from the destination, the server 100 searches for route information from the position of the branch near the destination to the destination, You may provide to the portable terminal 200 with map information.

  In the above-described embodiment, a distribution map is placed at each branch, but a large wide area map may be posted at each branch. If the branch route information from the position of the branch at the current location to the location of the branch close to the destination is described in this wide area map, the route information to the destination can be roughly grasped. The wide area map may be captured by the code acquisition unit 206 of the mobile terminal 200 and stored in the storage unit 203.
