DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of an urban disaster prevention system according to the present invention will be described with reference to the drawings.

As shown in FIG. 1, an urban disaster prevention system according to the present invention comprises a plurality of terminals 10 and a disaster information center 11.
And the information between them is GPS
It is transmitted and received using satellites 12, digital broadcast radio waves 13, mobile phone radio waves 14, and the like. Further, the disaster information center 11 can be established via a network such as the Internet, and can be located in an area that does not suffer from a disaster.

The terminal 10 has a structure capable of supporting a navigation system, that is, a function of displaying at least a map and displaying a mark indicating the current position of the terminal. In addition, this map shows, in particular,
It has a dedicated layer function that can display necessary information at the time of disaster such as hospitals, fire departments, disaster volunteer organizations, etc.

The dedicated layer function can be called from any of the pages displayed on the terminal device 10 and can be called and displayed. When an individual point is hit, the details of the facility or the like that hit the point are displayed. It displays information.

When the dedicated layer function is operating, the function of receiving the radio wave 13 of the digital broadcast is automatically turned on, and the information can be updated at any time. Information can be displayed automatically.

As shown in FIG. 8, when two emergency call buttons are simultaneously pressed or at least one of them is pressed strongly for a certain period of time, the terminal 10 enters an emergency signal transmission mode, and the terminal 10 displays its own safety information together with the current position. Can be transmitted. The emergency signal can be transmitted by pressing the icon 15 that can be pressed with a finger. Icons 15 with a high degree of urgency are arranged on the first page of the display screen of the terminal device 10, and icons having relatively marginal contents are arranged on the second and subsequent pages. Icon 15,
Contents that cannot be conveyed by only 15... Can be transmitted as character information. Furthermore, if no input has been made for a certain period of time after entering the emergency signal transmission mode for some reason, the terminal device 10 automatically transmits a "rescue required" signal. This emergency signal is used to avoid circuit congestion.
Voice transmission is not performed, and the emergency signal is transmitted to the disaster information center 11 and a pre-registered destination.

The disaster information center 11 prepares a rescue system based on the emergency signal from these terminals according to the content of the safety of the person who owns the terminals. Recipients other than the disaster information center 11 receiving the emergency signal can automatically and continuously receive the signal.
The terminal 10 can be connected to one server to confirm the safety of an acquaintance or the like.

The page displayed on the terminal device 10 is provided with an operation manual in an emergency, and when the user is upset, or when he / she does not think of it, the user can operate according to the displayed items. Data can be displayed.

This dedicated layer function is also used in an area where the terminal 10 is located, as shown in FIG. Disaster Information Center 1 automatically indicates the location of the disaster area on the map showing the disaster situation
1 and edited and sent back. This function is based on the fact that the more terminals 10 are scattered in an area where the population is concentrated, such as a city, the more the collected data has the accuracy and precision of the disaster state in a specific area. Become. For example, if a map of the area where the terminal device 10 is located is displayed, it is very clearly known on the map that traffic is stopped, a fire has occurred, and the evacuation route is in a better direction. You can do it. In addition, this function can be similarly performed in other areas, for example, workplaces and homes. When a map of a target area is displayed, the disaster situation in the area can be easily recognized.

Next, the terminal 10 having such a function will be described.
The operation when an earthquake actually occurs will be described.

When a large-scale disaster such as an earthquake occurs, the countermeasures are as follows: up to 72 hours after the occurrence of the earthquake (status grasp, evacuation, rescue phase), up to one week after the occurrence of the earthquake (evacuation life phase), It can be divided into stages up to one month after the earthquake (restoration / reconstruction phase).

When an Earthquake Occurs As shown in FIG. 4, the terminal device 10 blinks and emits a warning sound when it receives a notice signal that an earthquake occurs. The warning sound is, for example, "Earthquake! It starts to shake in about 20 seconds. Stop the fire and protect yourself. In 15 seconds, start to shake. Protect yourself. In 10 seconds.
... ”. The warning signal for predicting that an earthquake will occur in this way was embodied in a simulation that assumed the same type of earthquake as the Great Kanto Earthquake, and the epicenter at this time was the first wave off the coast of Sagami Bay. It took about 25 seconds to get to downtown. In the present invention, as shown in FIG.
When there is a sensor 17 near the epicenter 16, as shown in FIG. 3, when this information is transmitted from the disaster information center 11, the terminal device 10 can issue a warning within 10 seconds. That is, information that detects the occurrence of this earthquake is first relayed by the disaster information center 11 and transmitted to each terminal 10 by being superimposed on the digital broadcast radio wave 13 to directly damage human lives due to the earthquake. Try to keep it a little. Since the digital broadcast radio wave 13 includes a signal for turning on the power of the terminal device 10, a warning sound can be generated even for the terminal device 10 that is turned off. .

Up to 72 hours after the earthquake (Situation grasp, evacuation, rescue phase) After the earthquake, as shown in FIG. 5, various sensors arranged in the area report the damage situation to the disaster information center. Start sending all at once. Normally, a sensor in a gondola of an elevator 18 used for operation management, an altitude camera 19 installed on a building roof, and the like also send various information to the disaster information center 11. Police 20 and firefighting 2
1. Information that the SDF 22, the government 23, and the like independently obtain is also sent to the disaster information center 11.

As shown in FIG. 6, the terminal 10 also records a nearby disaster situation and sends it to the disaster information center 11 so that a more specific disaster situation in a specific area can be reported.
The data sent from the terminal device 10 is compressed in the terminal device 10 in advance in order to avoid line congestion, so that transmission can be completed instantaneously. The transmission information data of the disaster situation may be used only by a user having a specific license in order to avoid misuse such as hoax or terrorism.

The disaster information center 11 checks the reliability of the information received from various parts of the area, plots it on a map through an editing process such as organizing the information received repeatedly, and plots it on a map. It is superimposed on the digital broadcast radio wave 13 as a layer and transmitted to all the terminals 10 at once. By receiving the digital broadcast radio wave 13, each terminal device 10 receives the temporary damage situation 24, the evacuation information layer prepared in advance, and the current position of the terminal device 10 as shown in FIG. Display the nearest evacuation site on the screen and provide information necessary for safe evacuation. However, since the accuracy of the disaster information is not always guaranteed 100%, evacuation guidance such as suggesting an optimal evacuation site and indicating a route to the evacuation site is not performed. In addition, temporary realities such as temporary shelters and information on shelters are constantly updated and added.

Further, the disaster information center 11 simultaneously transmits the whole information of the earthquake and the earthquake at the level broadcasted on television, radio, etc., such as the seismic intensity at the epicenter and various places, the number of victims, etc. The terminal device 10 displays this on another page. That is, this terminal 1
In the case of 0, general disaster information is secondary, and data actually required in a specific area is displayed with priority.

Until one week after the earthquake (evacuation life phase) At this time, each evacuation center gathers information on evacuees, evacuation center facilities, supplies, etc. at the disaster information center 11, and the disaster information center 11 Is transmitted to the terminal device 10 while constantly updating the information. It also transmits information on administrative services and mobile hubs such as water trucks. On the terminal device 10 side, as shown in FIG. 9, such information can be obtained as a window that opens when the position of the evacuation site is clicked, or as searchable text information. Such information can also be used as a database for optimally delivering goods and allocating evacuees and volunteers. At the same time, as shown in FIG. 10, the restoration information 26 of the lifeline such as the infrastructure and the electric and gas water is always transmitted.

Up to one month after the earthquake (restoration / reconstruction phase) The reproduction status of the infrastructure and the lifeline is transmitted in more detail. In addition, as shown in FIG. 11, information 27 on temporary housing and information on an administrative window that is open for disaster-stricken living are also handled, and various application procedures relating to administration can be performed via a terminal device. ing. In addition, unexpected dissatisfaction and stress may occur in a long-term disaster life, and regular questionnaire surveys are conducted to obtain such opinions. The data collected in this way is not an ad hoc measure, but rather valuable data that aims to rebuild a city that is resilient to disasters by frequently collecting the real voice of each inhabitant emitted in real time after the disaster Saved as
used.
