DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0011]
(First embodiment)
FIG. 1 is a block diagram showing a configuration of an evacuation guidance system according to the first embodiment of the present invention.
[0012]
In FIG. 1, the evacuation guidance system includes a guidance host device 1, a network 2, a GPS (Global Positioning System) -equipped mobile phone 3, a map information server 4, and a disaster related information server 5.
[0013]
In the evacuation guidance system of the present invention, a wireless communication terminal having a position display means wirelessly communicates necessary disaster information with the guidance host device 1. In the following description, the evacuation guidance system will be described by taking as an example a case where the GPS mobile phone 3 is used as a wireless communication terminal having a position display means.
[0014]
The guidance host device 1 includes a database 1a that stores and stores information such as map information, traffic information, and disaster-related information, a CPU 1b, a bus 1c, and a CCU (communication control means) 1d. Information such as roads, railways, buildings, signs, signboards, marks, and the like is recorded in the map information of the database 1a.
[0015]
The guidance host device 1 then provides traffic information and disaster information input from its own device, the latest map information obtained from the map information server 4 via the network 2, and disasters provided by various government agencies, local governments, companies, organizations, etc. It has a function of collecting disaster information such as weather, earthquake, tsunami, flood, and fire, evacuation site information and traffic information obtained from the related information server 5 and storing them in the database 1a.
[0016]
If only a part of these disaster-related information and map information is stored in the database 1a of the guidance host device 1 and information not stored in the database 1a is required, the map information server 4 and the disaster-related information server 5 May be obtained via the network 2 from the network.
[0017]
The CPU 1b manages the operation of the guidance host device 1 by monitoring and controlling signal transmission / reception between the database 1a and the CCU (communication control means) 1d via the bus 1c. In addition, information and data transmitted / received to / from the GPS mobile phone 3 via the CCU 1d are monitored and controlled. Then, the map information in the database 1a and the location information of the GPS mobile phone 3 are compared and collated, and an evacuation route guide from the location to the nearest evacuation location is created and transmitted to the GPS mobile phone 3.
[0018]
The CCU 1d monitors and controls data transmitted and received by the guidance host device 1, and is connected to the telephone network 21, the cellular phone network 22, the dedicated line 23, the Internet network 24, etc. constituting the network 2, and the guidance host device. Information is transmitted to and received from one CPU 1b. Among these, the mobile phone network 22 is used for communication between the guidance host device 1 and the GPS mobile phone 3. The telephone network 21, the dedicated line 23, and the Internet network 24 are used by the guidance host device 1 for communication with the map information server 4 and the disaster-related information server 5, but are not limited thereto.
[0019]
Communication between each network included in these networks 2 and the guidance host device 1 is performed according to a predetermined communication procedure (for example, selection of a network based on an address of data to be transmitted, transmission, or telephone network 21, mobile phone) Response to the telephone network 22, the dedicated line 23, the Internet network 24, etc.).
[0020]
Next, the outline of the evacuation guidance system controlled by the CPU 1b will be described with reference to FIG. The CPU 1b constantly monitors whether there is a request for evacuation guidance from the GPS mobile phone 3 via the network 2. If there is a request for evacuation guidance from the GPS mobile phone 3, it is notified to the CPU 1b via the CCU 1d and the bus 1c. The CPU 1d further receives the location information of the location including the latitude and longitude measured by GPS from the GPS mobile phone 3 through the same route.
[0021]
Then, the CPU 1b accesses the database 1a via the bus 1c, searches the map information in the database 1a based on the position information received from the GPS mobile phone 3, and acquires map information centered on the current location.
[0022]
Further, the CPU 1b searches the database 1a for the evacuation site closest to the location based on the location information received from the GPS mobile phone 3, and maps information covering the evacuation location from the location based on the previously searched map information. To get. Then, the CPU 1b creates route map information from the location to the evacuation site by using this map information and the route search program built in the CPU 1b.
[0023]
This route search program, for example, examines how to follow a road from the location based on the direction of the evacuation site, and selects a way to follow the road with the shortest distance from the few ways.
[0024]
Further, when there are a plurality of evacuation places near the location, priority rankings are selected according to predetermined criteria set in advance, evacuation places are selected, route guidance is created, and guidance is provided to the mobile phone 3 with GPS.
[0025]
That is, the CPU 1b creates a route map in which the evacuation route is plotted on the map information. At this time, collation points such as place names, buildings, intersections, signs, and marks are recorded on the map information of the evacuation route. Then, a list is created in which the matching points in the created route map information are arranged in order as targets for route guidance to the evacuation site. This list may be edited into a text sentence edited into a sentence explaining how to follow the road according to the order.
[0026]
The route map information created by the CPU 1b in this way is stored in the database 1a and transmitted to the mobile phone 3 with GPS via the CCU 1d and the network 2.
[0027]
On the other hand, the GPS mobile phone 3 has a GPS receiver function for transmitting the position information acquired by the GPS receiver to the guidance host device 1 via the network 2, and in addition to characters and symbols on the display screen, A mark indicating the location can be displayed. In addition, the GPS mobile phone 3 has an input means for inputting various information using the key buttons.
[0028]
FIG. 2 is a block diagram showing a configuration of the GPS mobile phone 3 used in the first embodiment.
[0029]
The GPS mobile phone 3 includes a wireless transmission / reception unit 31, a GPS receiver 32, a CPU 33, a memory 34, an NCU 35, an audio circuit 36, a display unit 37, a plurality of key buttons 38, and a bus 39 for connecting them. .
[0030]
The GPS-equipped mobile phone 3 has voice call means, Web access means, and mail transmission / reception means such as characters / images via the mobile phone network 22. The CPU 33 creates a Japanese sentence from alphanumeric characters, hiragana, katakana, and symbols input from the key buttons 38 and displays the Japanese sentence on the display unit 37.
[0031]
The components other than the GPS receiver 32 of the mobile phone with GPS 3 have the same operations and functions as a general mobile phone, but receive GPS signals from GPS satellites to guide evacuation. The following functions are added to make it possible to make requests.
[0032]
That is, the voice circuit 36 is used for a voice call of a cellular phone by a voice channel, but is also used as an output unit for voice guidance for evacuation route guidance sent from the guidance host device 1 in a data packet.
[0033]
The GPS receiver 32 receives signals from GPS satellites and sends demodulated position information to the bus 39. When there is an operation control input (command) related to evacuation guidance from the key button 38, the CPU 33 sequentially stores the position information flowing in the bus 39 in the memory 34, and further via the wireless transmission / reception unit 31 and the mobile phone network 22. The position information is transmitted to the guidance host device 1.
[0034]
The procedure for confirming the location using the GPS mobile phone 3 and route guidance to the evacuation site will be described below.
[0035]
When the owner of the mobile phone with GPS 3 wants to request “route guidance to an evacuation site”, for example, “F and *” of the key buttons 38 set in the command for the request are simultaneously pressed.
[0036]
Then, the CPU 33 of the GPS mobile phone 3 stores the latitude / longitude position information received by the GPS receiver 32 in the memory 34 as location data. At the same time, the NCU 35 is activated, and a telephone number (for example, 057-OOOO-xxx) that can be connected to the guidance host device 1 is automatically dialed to establish a dial connection. Request command for “route guidance” is transmitted to the guidance host device 1 via the mobile phone network 22.
[0037]
The CCU 1 d of the guidance host device 1 performs incoming call processing with the mobile phone network 22 and connects between the CPU 1 b and the GPS mobile phone 3. When this connection is established, data packets are transmitted and received between the guidance host device 1 and the GPS-equipped cellular phone 3 via the cellular phone network 22.
[0038]
When the CPU 1b of the guidance host device 1 determines that the incoming call from the GPS mobile phone 3 is a request for “route guidance to the evacuation site”, the location from the location of the GPS mobile phone 3 to the evacuation site as described above. The work of creating map information for guiding the route and returning the map information to the GPS mobile phone 3 is started. Since transmission / reception of signals between the guidance host device 1 and the mobile phone 3 with GPS uses packet data communication of the mobile phone network 22, the transmission / reception time does not require several seconds.
[0039]
FIG. 3 is a diagram showing an example of a display screen of “Location confirmation” in “Route guidance to evacuation site” displayed on the display unit 37 of the GPS mobile phone 3. The location of the mobile phone with GPS 3 and the evacuation site are displayed on the same screen on the schematic diagram. The location is represented by a star in the center of FIG. 3, and the name and distance of the evacuation site are displayed at the bottom of the screen. From the guidance host device 1, map information of a scale set in advance is transmitted to the GPS mobile phone 3.
[0040]
When the map information display scale is changed, the map display scale can be increased by pressing, for example, the key button 38 “F, 9, 9, #” as a scale enlargement command. A scale reduction command is also prepared.
[0041]
Therefore, when the display of the route map to the evacuation site is finished on the display unit 37 and the map information is to be stored, for example, when “#” of the key button 38 is pressed, the map is stored in a predetermined area of the memory 34. When the user wants to see the map information stored in the memory 34 after disconnecting the cellular phone line, for example, by pressing “F, 6, #” of the key button 38, the CPU 33 displays the map on the display unit 37. Redisplay information.
[0042]
Next, the route guidance to the evacuation site to which he / she aims (this is called “evacuation route guidance”) will be described.
[0043]
The database 1a of the guidance host device 1 has, as map information, position information linked to the latitude and longitude of the map using addresses, postal codes, telephone numbers, company names, facility names, and the like as keys. Therefore, the guidance host device 1 can collate the position information with the GPS position information received from the GPS mobile phone 3 and set the location of the GPS mobile phone 3 and the position of the evacuation place on the map.
[0044]
Further, the database 1a accumulates hazard maps around the disaster occurrence area in cooperation with map information from the disaster information database. This hazard map is created for disasters that are expected in normal times, and is created assuming the danger of entering, entering, or passing through the area for floods, fires, ground collapses, etc. When a disaster actually occurs, this hazard map is updated based on actual information.
[0045]
Therefore, the CPU 1b searches for the shortest route from the location to the evacuation site by using the route search program and refers to the hazard map and the shortest route to bypass the dangerous route or select an evacuation route for selecting another road. create.
[0046]
FIG. 4 is an example of a display screen of the display unit 37 displaying “evacuation route guidance”.
[0047]
4 (a) and 4 (b) respectively show the map information display screen in which the scale of FIG. 3 is enlarged and one screen is 500 m square. FIG. 4B shows a display screen when shifted downward from FIG. 4A, the location of the GPS mobile phone 3 is indicated by a star mark, and the location of the evacuation site is indicated by a double circle whose inner circle is black in FIG. 4B. Has been.
[0048]
FIG. 5 is an example of a table showing the “risk coefficient” of the road created based on the hazard map corresponding to the map of FIG. This table is stored in an internal storage device (not shown) of the guidance host device 1 or in the database 1a.
[0049]
In FIG. 5, symbols such as X1 and X2 are accumulated in the map information database of the database 1a, and numbers corresponding to road intersections, buildings, targets, etc. shown on the display screen of the evacuation route guidance in FIG. Xq-X1, X1-Xp, etc. indicate road sections between these targets.
[0050]
Further, the “risk coefficient” in FIG. 5 classifies the risk level in the road section, and the disaster status indicates the failure that has caused the risk.
[0051]
FIG. 6 is a diagram showing evaluation criteria for “risk coefficient” of road sections in the hazard map, and corresponds to “risk coefficient” in FIG. For example, “risk coefficient 5” in FIG. 6 is impassable, and “risk coefficient 4” is a road section that should be used only when there is no other route although it can pass. Show.
[0052]
These risk factors are set in the database 1a based on road information obtained from a report to the police, fire department, local government, etc. when a disaster occurs.
[0053]
When the user of the mobile phone with GPS 3 confirms the location from FIG. 3, the user requests the route guidance to the evacuation site by pressing “F and #” on the key buttons 38 and transmits to the guidance host device 1.
[0054]
The CPU 1b of the guidance host device 1 searches for route candidates using a route search program. The shortest distance is found to be the route X0-X2-X3-X4-X5-X9 as the first route. (In FIG. 4, one-dot broken line.)
Therefore, in order to determine the danger situation for this route, the total “risk level” of the route is calculated with reference to the table shown in FIG.
[0055]
The risk level is a value obtained by multiplying the above “risk coefficient” by the “distance coefficient” shown in the table of FIG. 5. For example, X2-X3 is “risk coefficient 2”, “distance coefficient 0. Since “5”, the “risk” is “1”.
[0056]
Similarly, when the CPU 1b obtains the “risk” for X0-X2, 2, X2-X3, 1..., X5-X9, 1.5 and adds up, the total “risk” for the first route is “ 10 ".
[0057]
As another route having the same distance, there is a second route X0-X1-Xp-X6-X7-X10-X9 (dotted line in FIG. 4). The “risk level” is “9.25”.
[0058]
Further, the route search program searches for a candidate for the route X0-X2-X3-X6-X7-X10-X9 as the third route, but referring to the table in FIG. 5, since X3-X6 cannot pass, the CPU 1b Excludes this route from evacuation route candidates.
[0059]
Therefore, comparing the first and second, since the “risk” of the second route is “9.25”, which is lower than “10” of the first route, the second route is determined as the evacuation route. To do.
[0060]
On the other hand, when a disaster occurs, the road damage situation as described above cannot be set in stages, and it may be possible to set only whether or not traffic is possible. In such a case, as a method for determining an evacuation route, a candidate for a route with the shortest distance is guided as an evacuation route from evacuation route candidates based on a combination of roads that can be passed.
[0061]
The evacuation route thus determined is stored in the internal memory of the guidance host device 1 as “evacuation route guidance” data, and transmitted to the GPS mobile phone 3 via the CCU 1 d and the network 2.
In the GPS mobile phone 3, according to the “evacuation route guidance” transmitted from the guidance host device 1, for example, the area from the location to the evacuation site is plotted in red (dotted line in FIG. 4) and displayed on the display unit 37. Further, it is stored in the memory 34. Further, the location of the GPS-equipped mobile phone 3 may be plotted on the map in blue, for example.
[0062]
When the GPS mobile phone 3 moves toward the evacuation site, the locus of the position information from the GPS is displayed in blue on the display screen so that the red evacuation route guidance and the blue locus coincide with each other. You can also move to the evacuation site while checking the route. In the example of FIG. 4, the map direction is always displayed with north as the upper direction on the screen, but the traveling direction may always be displayed on the screen.
[0063]
When the CPU 33 of the GPS mobile phone 3 receives the map information of the evacuation route and the data of the route guidance text from the guidance host device 1, the CPU 33 temporarily stores these data in the memory 34 and displays the map information on the display unit 37. And a route guidance sentence may be displayed on the display unit 37.
[0064]
FIG. 7 shows a modification of the position information detection means using GPS.
[0065]
In FIG. 7, a GPS receiver 71 and a PDA (personal digital assistant) 72 are combined in place of the GPS mobile phone 3, and a mobile phone 3 </ b> G capable of data communication is connected to the PDA 72.
[0066]
