The rescuer information acquisition module 201 acquires a rescue request signal and current location information of the rescuer and saves it in the rescuer database 141 configured by storage. The evacuee information acquisition module 202 acquires current position information of the evacuees who are going to evacuate. The evacuee information acquisition module 202 further obtains information (e.g., current position, evacuation route, number of people who can be rescued) of evacuated evacuees who are set to work as a private rescue team. To the private rescue team database 142. In particular, if the difference (time margin) between the time limit to reach the evacuation site and the estimated arrival time that can be predicted through the evacuation route is greater than or equal to a predetermined time (for example, 5 minutes) required for rescue, the private rescue team Register in the database 142. In other words, registration in the private rescue team database 142 is performed only when there is sufficient time for evacuation and it can be determined that another person can be rescued.

The evacuation site / route determination module 203 determines an evacuation site and an evacuation route for the evacuees. The evacuation site / route presentation module 204 presents the determined evacuation site and evacuation route to the evacuee. Further, the rescuer private rescue team matching module 205 determines whether or not there is a rescuer to be presented to the evacuated evacuee. Specifically, whether or not there is a rescuer who is located on the evacuation route of the evacuees registered in the private rescue team database 142 is referred to the current location information of the rescuer required in the rescuer database 141. judge. The rescuer information presentation module 206 presents a predetermined number of rescuers on the evacuation route in order from those closest to the evacuee. Note that the rescuer information presentation module 206 indicates that the rescuer needs to be able to determine that a rescuer who is away from the evacuation route determined by the evacuation site / route determination module 203 can reach the evacuation site within a predetermined time. The current position may be additionally presented.

FIG. 3 is a diagram for explaining the configuration of the rescue request apparatus 101 in detail. The rescue request apparatus 101 is configured to be connectable to a display such as a television 110. First, the rescue request device 101 includes a rescue switch 301 for a rescue requester to inform the system of the will of the rescue request, and a self-evacuation switch 302 for communicating to the system that rescue is not necessary and can be evacuated by oneself. ing. Also provided are a number input button 303 for inputting the number, age, telephone number, etc. of rescuers, and an English / Japanese button 304 for switching English / Japanese in the display image and output sound. Yes. This is a configuration that is assumed to be installed in a hotel or the like and operated by a foreign tourist.

The rescue request apparatus 101 further includes a wireless communication unit 305 including a wireless communication antenna and a modem, and can perform stable information communication even in a large-scale disaster using a technique such as Wimax (registered trademark), for example. It has a configuration. When the wireless communication unit 305 detects the presence of a rescue requester, the wireless communication unit 305 transmits a rescue request signal to the rescue support server 143 together with the current location information of the rescue requester.

The rescue request device 101 is also provided with a human sensor 307. There is a possibility that an object may collide due to the impact of an earthquake and the rescue switch 301 or the self-evacuation switch 302 may be pressed. In such a case, in order to avoid misrecognizing that there is a person in need of rescue, the mechanism is confirmed by the human sensor 307. Specifically, a rescue request signal is transmitted when a rescue operation is received by the rescue switch 301 and the presence of a rescuer is detected by the human sensor 307. That is, the combination of the rescue-required switch 301 and the human sensor 307 functions as a detection unit that detects the presence of the rescuer. After transmitting the rescue request signal, the wireless communication unit 305 confirms whether the human sensor 307 detects that there is a person nearby at regular intervals, and repeatedly transmits the rescue request signal.

The rescue request device 101 includes a battery 309. This battery 309 takes into consideration the possibility of a power outage during a large-scale disaster. Upon receipt of disaster occurrence information, the battery 309 supplies power to the television 110 in addition to power supply for driving the rescue request apparatus 101 itself. Realize. At times other than disasters, electricity is supplied from a wall outlet or the like via the power cable 315, and power is supplied to the television 110 via the power cable 350.

Even if this current position is obtained from a GPS (not shown), an installer or an installation assistant (such as a person in charge of a municipality or a serviceman of an electric shop) when installing the rescue request apparatus 101
May be manually entered.

The audio output unit 311 is a speaker that outputs various messages such as an operation method of the rescue request apparatus 101 as audio. Since the audio output unit 311 is provided, even if the television 110 is broken due to an earthquake or the like, it is possible to output a message that prompts the minimum necessary operation. For example, when the voice output unit 311 transmits a rescue request signal and the human sensor 307 no longer detects that there is a person nearby, the voice output unit 311 prompts the rescuer who needs to press the rescue switch 301 again. Output.

The video output unit 312 outputs video data to the television 110. As the video data, for example, an evacuation place and an evacuation route can be considered in addition to a message for prompting the operation of the rescue request apparatus 101.

The audio data and video data output from the audio output unit 311 and the video output unit 312 are stored in a storage (not shown). The wireless communication unit 305 may be driven periodically (for example, once every six months) to download the latest evacuation site and evacuation route from the rescue support server 143, such as the latest evacuation site and evacuation route. Is also stored in the storage.

The TV tuner 313 receives terrestrial digital broadcast from the antenna 330 and outputs video to the television 110 via the cable 340. The TV tuner 313 analyzes the content of the received television broadcast. As a result, it is possible to detect that a tsunami warning or a large tsunami warning has been issued.

The remote control signal receiver 314 receives a signal from the TV remote controller and controls the rescue request device 101. The rescue request apparatus 101 can be operated using the TV remote controller, for example, when a rescuer is bedridden in a bed separated from the rescue request apparatus 101.

FIG. 4 is a front view showing the external appearance of the rescue request apparatus 101. As shown in FIG. 4, on the front panel of the rescue request apparatus 101, a rescue required switch 301, a self-evacuation switch 302, and the like are arranged. From the audio output unit 311, “A large tsunami warning has been issued. Please evacuate immediately. If evacuation is difficult, press the“ Waiting for rescue ”switch or“ 1 ”on the TV remote control. Ask for help. If you can evacuate by yourself, press "2" on the evacuation switch or TV remote control. The evacuation site and evacuation route are displayed. If you と い っ た need English message please push “English Switch.” ”Is output. In addition, when the rescue-required switch 301 is pressed, a voice message such as “I request rescue now. Please input the number of people who need rescue” may be output.

FIG. 5 is a front view showing an external appearance when the rescue request apparatus 101 is connected to the television 110. A message similar to the voice message output by the voice output unit 311 is also displayed on the television 110. In addition, when the self-evacuation switch 302 is pressed, the television 110 displays an image of an evacuation place and an evacuation route output from the rescue request device 101. The messages shown in FIGS. 4 and 5 are merely examples. By outputting various messages, it is possible to obtain detailed information of the rescuer. For example, if information such as name, gender, age, telephone number, whether a wheelchair is necessary, whether it is blind, etc. can be used for rescue. Furthermore, if the information is stored in the storage in the rescue request apparatus 101 or the storage on the network when or before the rescue request apparatus 101 is installed, it is possible to save the input by the rescue requester himself at the time of disaster. Can be reduced. In that case, the registered rescue request candidate may be displayed on the television 110 and the rescue requester himself / herself may be selected.

FIG. 6 is a diagram showing the configuration of the rescuer database 141. The rescuer database 141 has information of rescuer number, position, and number of people as basic information. Furthermore, the name, age, sex, presence / absence of a disability, telephone number, etc. Detailed information is stored.

The evacuation site determination module 705 is a module for determining an evacuation site from disaster information and current position information. The route determination module 706 is a module for determining and displaying a route from the current position to the evacuation site determined by the evacuation site determination module 705. The determination and presentation of the evacuation site and the evacuation route may be performed in the rescue support server 143 or may be performed locally in the terminal of the smartphone 120.

It should be noted that when installing the evacuation support application 700 to the smartphone 120 or the like, it is desirable to display a message asking for participation in the private rescue team. For example, “This application is an application for presenting evacuation sites and evacuation routes in the event of a disaster. At the same time, it is also possible to receive information on rescuers. Whether or not there is an intention to act as a private rescue team. Answer me. Even if I receive information about the rescuer, I can choose not to go to rescue. " Of course, it is desirable to be able to change private rescue team settings at any time on the settings screen.

FIG. 8 is a diagram showing a configuration of an evacuation support application 800 bundled with the car navigation system. The evacuation support application 800 includes a setting module 801 for setting whether or not there is an intention to act as a private rescue team. Only when the setting module 801 is set to operate as a private rescue team, the rescue request server 143 receives information on a rescuer. In other words, the evacuation support application 800 does not receive the rescue requester information from the rescue support server 143 when the setting module 801 receives the information of the rescue requester and is not set. The evacuation support application 800 includes a display module 802. The display module 802 receives the position information of the evacuation site and the evacuation route to the evacuation site from the rescue support server 143 and displays them on the built-in display.

FIG. 9 is a sequence diagram showing a simplified process flow of the rescue support system 100 according to the present embodiment.

First, when a large-scale disaster occurs, the disaster information server 900 such as the Japan Meteorological Agency issues an alarm in step S901 and transmits the disaster information at the same time or immediately after. For example, in the case of a tsunami, the disaster information includes a branch site, a tsunami arrival location, a tsunami arrival time, a tsunami height, and a tsunami speed.

When the rescue support server 143 receives the warning and the disaster information in step S911, the rescue support server 143 prepares for the rescue support process. When receiving the warning and disaster information in step S921, the smartphone 120 and the car navigation system notify the user that a tsunami is coming and start the rescue support application at the same time in step S922. The smartphone 120 may automatically start the rescue support application, but may start the display after displaying and confirming a message such as “Do you want to start the rescue support application?” To the user.

When the rescue support application is activated on the smartphone 120, the user environment information is transmitted to a preset address (rescue support server address) (S923). As the user environment information, in addition to the user position information and speed information, when the user is in a vehicle, the number of people who can get on the vehicle is included, and the information is sent to the rescue support server 143. .

When the rescue support server 143 receives the user environment information in step S913, the rescue support server 143 determines whether or not there is an intention to become a private rescue team, and if there is an intention, registers it in the private rescue team database 142. In step S914, map elevation data around the current location of the user is read from the map elevation database. In step S915, the rescue support server 143 determines an evacuation place and an evacuation route for each evacuee.

Finally, when the rescue support server 143 transmits the evacuation navigation information to the smartphone 120 (S916), the received evacuation navigation information is displayed on the smartphone 120 (S924). That is, the evacuation place and the evacuation route are displayed.

On the other hand, when the rescue request apparatus 101 receives the alarm and disaster information in step S931, the rescue request apparatus 101 proceeds to step S932, switches to battery driving, and outputs a message by voice and / or video in step S933.

Next, in step S934, a pre-rescue person is detected with reference to the detection results of the rescue-required switch 301 and the human sensor 307. Further, in step S935, attribute information of the rescuer (position number, name, age, disability) Etc.). If the rescuer information is input, a rescuer signal is transmitted (S936).

In step S917, the rescue support server 143 obtains / collects rescuer information required and stores the rescuer information in the rescuer database 141. At this time, for example, when a rescue request signal is repeatedly acquired, a condition such as storing rescuer information in the rescuer database 141 may be added. In step S918, the rescuer information stored in the rescuer database 141 is matched with information related to the private rescue team. If a private rescue team capable of helping the rescuer is found, the process proceeds to step S919 to send rescuer information to the rescue support application such as the smartphone 120 and request the rescue.

Next, the evacuation place and evacuation route determination method performed in step S915 will be described with reference to the flowchart of FIG.

First, in step S1001, the evacuable distance is calculated using the user environment information. For example, the time from the current time to the tsunami arrival time is added to the walking speed and traveling speed during evacuation.

Next, in step S1002, a candidate list of evacuation sites is generated. For example, a circle with a radius of evacuable distance is drawn on the map centered on the current position of the user, and a point where the altitude is sufficiently higher than the tsunami height among the multiple points existing in the circle The evacuation site candidate list is generated in order from the highest altitude. If the elevation is sufficiently higher than the tsunami height, a location far from the coast, a location close to the user's current location, or a high-profile location (supermarket, city hall, school, hospital, station, etc.) is a highly evaluated evacuation site candidate. . That is, for a plurality of points, the points are added based on the altitude, the distance from the coast, the ease of understanding of the place, etc., and the ease of evacuation and safety are evaluated comprehensively. A list of candidates for evacuation sites is generated by listing the evacuation sites that have the highest evaluation as evacuation sites.

Next, in step S1003, an evacuation route is generated for each evacuation site candidate, and in step S1004, the evacuation site and the evacuation route are evaluated. In the map elevation data, roads that are not suitable for evacuation are registered in advance, such as roads that are easily congested, places with low elevations, roads along rivers, and roads extending from the coastline. Therefore, an evacuation route that does not pass through the road that is not suitable for evacuation is generated. Among the evacuation routes that do not pass the road that is not suitable for evacuation, the route with the shortest expected time for evacuation and the route that is easy to evacuate are selected. In determining the expected time, it is desirable to use the altitude data and take into account the slope. Recommended evacuation routes change over time. Therefore, the evacuation route is updated as needed unless evacuation start processing is performed. For example, in the case of a tsunami, there are fewer road options that can be taken according to the time elapsed since the earthquake. Finally, in step S1005, a highly evaluated evacuation place and evacuation route are determined.

The flow of processing performed in the rescue request apparatus 101 is shown in the flowchart of FIG. The following processing is realized by a CPU (not shown) executing a program stored in a ROM (not shown) or the like of the rescue request apparatus 101.

First, in step S1101, for example, when a tsunami warning is received together with a terrestrial digital video signal, the process proceeds to step S1102, a rescue request application is activated, and in step S1103, the battery driving is changed. At this time, if there is a connected TV, battery power is also supplied to the TV.

Next, in step S1104, the message stored in advance (see FIGS. 4 and 5) is displayed on the television, and the sound is output from the speaker. Next, it is determined whether or not a certain time has passed and the rescue switch 301 is pressed (S1105). If the rescue switch 301 is not pressed, the process proceeds to step S1109 to determine whether or not the self-evacuation switch 302 is pressed. If none of the switches are pressed, the process returns to step S1104 to output a message prompting the operation again. If it is determined in step S1109 that the self-evacuation switch 302 has been pressed, the process advances to step S1110 to determine whether the human sensor 307 is on. When the self-evacuation switch 302 is pressed and the human sensor 307 is turned off, it is determined that there is no person after evacuation, and the process is terminated.

On the other hand, if the rescue-required switch 301 is pressed, the process proceeds from step S1105 to step S1106, where further information (number of people, age, etc.) about the rescuer is entered and the entered information is stored. In step S1107, it is determined whether the human sensor 307 is on. In the case where the presence of a person is not felt despite the rescue switch 301 being pressed, it is determined that a malfunction has occurred and the process returns to step S1104. If the rescue switch 301 is pressed and the human sensor 307 is on, it is determined that a rescuer is in need, and the process proceeds to step S1108, where a rescue signal and information of the rescuer are transmitted.

It should be noted that it is desirable to perform a process for determining whether or not the rescue-required switch 301, the self-evacuation switch 302 and the human sensor 307 are out of order, and to perform the above-described process after determining that there is no failure. In addition, the process of stopping the transmission of the request signal may be performed when the pressing of the rescue switch is repeatedly requested and the rescue switch is not pressed for a certain period.

FIG. 12 is an external view of the rescue request apparatus 101 and the television 110. As shown in FIG. 12, the rescue request apparatus 101 may be connected to a Web camera 1201 and an image of a rescue requester waiting for rescue may be transmitted to the rescue support server 143.

FIGS. 13 and 14 are diagrams showing examples of screens displayed on the smartphone 120. FIG. FIG. 13 shows a screen example 1300 when a large tsunami warning is issued. In addition to the message to notify the warning, information on the estimated tsunami height and estimated tsunami arrival time is displayed in addition to the epicenter, depth, and scale. Furthermore, the time that can be used for evacuation and the time required to reach the shortest evacuation site are displayed. When the route search button 1301 is selected here, the screen of FIG. 14 is displayed.

FIG. 14 shows an example screen 1400 for navigating the evacuees to the evacuation site. This screen shows that there is an 85-year-old male rescuer on the evacuation route. The evacuees head for rescue after comparing the time left for themselves (for example, the time until the tsunami arrives), the time required to arrive at the evacuation site, and the location and condition of the rescuer. It can be determined whether or not. The rescue support server 143 side primarily selects evacuees who can act as private rescue teams, but it is up to the evacuees themselves to decide whether or not to go to rescue.

15 and 16 are diagrams showing examples of navigation screens 1500 and 1600 that two-dimensionally display an evacuation place and an evacuation route to be aimed from the current location. FIG. 15 shows an example of a 2D map, and FIG. 16 shows an example of a 3D map. Both display the time 1501 to the shortest evacuation site and the time 1502 to reach the tsunami. Furthermore, the evacuees are provided with an input field 1503 for inputting the number of people who can board the vehicle, and when the number of people input here is 0, the rescuer is not displayed. Further, on this screen 1500, the distance to the destination, the direction to go, and the like may be displayed. Further, on this screen, a warning is displayed for roads and areas that should never be traveled.

In addition, a button 1504 for inputting the will of whether to go to rescue may be prepared. In that case, the rescue support server 143 can grasp who, who, and who went to rescue.

FIG. 17 is a diagram showing an example of a screen on which rescuer information and private rescue team information collected by the rescue support server 143 are mapped. As shown in FIG. 17, the rescue support server 143 can display the position on the map and the detailed information of each of the rescuers 1701 to 1707 requiring rescue. It is also possible to display how many private rescue teams are heading for which rescuers are needed. By generating such an integrated screen of collected data and transmitting it to the fire department headquarters or the like, it is possible to determine which location is effective for rescue.

As explained above, according to the present embodiment, it is possible to grasp where and how many rescuers are needed, and to convey the information to the victims who are in the process of evacuation, so that the refugees can afford to be rescuers. It is possible to reduce the number of victims in the affected area. On the other hand, by selecting carefully the rescuer information and selecting the refugee information and matching them, it is possible to effectively prevent the rescuer and the refugee from collapsing. For example, for refugees who own cars and have enough space for passengers and have sufficient time to reach the evacuation site (disasters in the middle of evacuation), Present. The final decision on whether or not to rescue the rescuer is left to the evacuees, but if there is sufficient room, the rescuer can be rescued. By not providing the refugee with information on the rescuer who is difficult for the refugee to rescue, no unnecessary guilt is given.

The present invention may be applied to a system composed of a plurality of devices, or may be applied to a single device. Furthermore, the present invention can also be applied to a case where a rescue support program that realizes the functions of the embodiments is supplied directly or remotely to a system or apparatus. Therefore, in order to realize the functions of the present invention on a computer, a program installed in the computer, a medium storing the program, and a WWW (World Wide Web) server that downloads the program are also included in the scope of the present invention. .
This application claims the priority on the basis of Japanese application Japanese Patent Application No. 2011-161470 for which it applied on July 24, 2011, and takes in those the indications of all here. While the present invention has been described with reference to the embodiments, the present invention is not limited to the above embodiments. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.
