Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information system capable of realizing a speedy and accurate administrative response by centrally collecting and managing related information for a sediment-related disaster caused by rainfall.

[0002]

2. Description of the Related Art Sediment-related disasters due to rainfall are characterized by the fact that the most tense times of caution, evacuation, and rescue last long. Therefore, the river erosion control office and the disaster response headquarters set up at the municipal offices, which are responsible for collecting and transmitting information in case of sediment-related disasters, are required to grasp the situation promptly and respond appropriately.

On the other hand, since the river erosion control office and the disaster response headquarters have different supervisory ministries, it cannot always be said that information is exchanged promptly.
That is, the river erosion control office that keeps track of this information by means of rain gauges, debris flows, and landslide monitoring devices (hereinafter referred to as debris flow meters and landslide meters) will be able to confirm that the erosion control dams and landslides are likely to occur when a sediment disaster due to rainfall is predicted. Prioritizing the request for stone removal by road workers, the disaster countermeasure headquarters established at the municipal offices were only informed of this information regularly or by fax upon request.

In addition, even at the disaster countermeasures headquarters set up at municipal offices, it is rare for the river erosion control office to be proactively notified of the precursors of disasters such as rockfalls in areas where landslides are steeply collapsed. It was

Further, since the place of occurrence of the rainfall information, the sediment-related disaster occurrence prediction information, and the sign information is specified by the place name address, etc., the person in charge expands the map from the place name address etc. and confirms the topography of the place of occurrence. Therefore, it was necessary to predict the extent of the impact and take measures such as evacuation advisories to the local residents.

[0007]

As described above, in a situation where a sediment-related disaster due to rainfall is predicted and when a sediment-related disaster actually occurs, the river erosion control office and the disaster response headquarters will exchange information. Due to the lack of a system to notify, the river erosion control office and the disaster response headquarters had to deal with each individually.

[0008] Therefore, even useful information could not be grasped promptly for the information that other administrative agencies had control, and the countermeasures were sometimes delayed.

The present invention has been made in view of the above problems, and is to construct an information system capable of realizing speedy and appropriate administrative response to a sediment disaster caused by rainfall.

[0010]

A sediment-related disaster risk management system according to the present invention is a sediment-related disaster risk management system that mediates information exchange between administrative authorities and residents by using a computer and a network for sediment-related disasters caused by rainfall. ,

And a transmission means for transmitting.

As described above, according to the sediment disaster risk management system of the present invention, it is possible to realize a speedy and appropriate administrative response to a sediment disaster caused by rainfall.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the earth and sand disaster risk management system according to the present invention will be described in detail below with reference to FIGS.

The landslide disaster crisis management system according to the present invention centrally collects and manages information obtained by related administrative agencies, shares the information, and retrieves necessary information in real time by each administrative agency and residents. By doing so, a speedy and accurate administrative response to sediment-related disasters due to rainfall will be realized.

FIG. 1 shows the overall configuration of an embodiment of the present invention.

As shown in FIG. 1, the river erosion control office 2
The terminal 2a installed at 1, the terminal 3a installed at the disaster response headquarters 22 of the municipal office, and the server 4a installed at the disaster prevention information providing site 23 for centralizing and centrally managing data related to sediment-related disasters are on the Internet 11 Tied through.

On the terminal 2a installed in the river erosion control office 21, a rain gauge 1a _i (i =
1, 2, ...), debris flow meter 1b _j (j = 1, 2, ...
・), And measurement data from the landslide gauge 1c _k (k = 1, 2, ...) Is transmitted by wire or wirelessly, and these data are stored in the database of the terminal 2a installed in the river erosion control office 21. It is stored in 2b. In addition, the database 2 of the terminal 2a installed in the river erosion control office 21
In b, data on dangerous places where sediment-related disasters are expected to occur, data showing the status of erosion control equipment at each location, and the possibility of sediment-related disasters due to the relationship between the amount of rainfall and the rainfall time at that location. The predicted snake curve data is stored in advance.

Here, the snake curve means, for example, as shown in FIG. 6, the horizontal axis represents the effective rainfall with a half-life of 72 hours, and the vertical axis represents the effective rainfall with a half-life of 1.5 hours. The possibility of a landslide disaster is visually indicated by showing the area where a disaster is predicted on the graph and by indicating the point in the graph where the current rain is. We take into consideration the fact that the amount of cumulative rainfall until the occurrence of a sediment-related disaster differs between long-lasting rain and temporary heavy rain such as concentrated heavy rain.

The terminal 3a installed in the disaster response headquarters 22 of the municipal office has a rain gauge 1d independently installed by the municipal office.
The measurement data from _l (l = 1, 2, ...) Is transmitted by wire or wirelessly and is stored in the database of the terminal 3 a installed in the disaster countermeasure headquarters 22 of the municipal office. Also,
In the database 3b of the terminal 3a installed in the disaster response headquarters 22 of the municipal office, there is an evacuation center situation 22 showing the locations of evacuation centers where residents should evacuate in the event of a disaster and their acceptance system.
a, evacuees 22b who should evacuate to each evacuation center,
The data of the stockpiling status 22d of the evacuation route 22c and the evacuation site is stored. Furthermore, when a landslide disaster actually occurs, the data of the personal injury status of the injured / missing person 22e due to the landslide disaster and the data of people who have evacuated safely are also stored in the terminal 3a installed in the disaster response headquarters 22 of the municipal office. It is stored in the database 3b.

The server 4a installed on the disaster prevention information providing site 23 stores the data in the respective databases from the terminal 2a installed in the river sabo construction office 21 and the terminal 3a installed in the municipal government disaster countermeasures headquarters 22. The data is transmitted via the Internet 11. These data are stored in the database 4b of the server 4a installed in the disaster prevention information providing site 23. In addition, in the database 4b of the server 4a installed in the disaster prevention information providing site 23,
Geographic information data has been accumulated in advance for the area within the defined range.

Further, the data processed and processed in the server 4a installed in the disaster prevention information providing site 23 is the mobile terminal 7 owned by the members of the voluntary disaster prevention organization 24 and the sabo control station 25 (not shown) of the country / prefecture. Terminal installed in the country, terminal installed in the fire department 26 (not shown) of the country / prefecture, residents 27
You can browse through the Internet from your personal computer (not shown). In addition, when a sediment disaster is predicted, the server 4 installed in the disaster prevention information providing site 23
An instruction such as an evacuation recommendation is given to the residents 27 from a through the CTI 5 and the telephone network 12. In addition, the data processed and processed by the server 4a installed in the disaster prevention information providing site 23 and instructions such as evacuation advice to the residents are provided as necessary.
Residents 27 are notified via the Internet 11, CATV 6, and CATV network 13.

[0021] Conventionally, the river erosion control office 21 supervised by the Ministry of Land, Infrastructure, Transport and Tourism and the disaster response headquarters 22 of the municipal government office supervised by the Ministry of Internal Affairs and Communications may have different supervising ministries, so that mutual information exchange is not always prompt. Although it has not been said that this is the case, it is possible to extract mutually beneficial information in real time by mediating the disaster prevention information providing site 23 in this way, so it is predicted that sediment-related disasters will occur due to rainfall. In such situations, prompt and appropriate administrative response will be possible.

Here, the data processed and processed by the server 4a installed on the disaster prevention information providing site 23 differs in the level of disclosure of the information depending on the other party to which the data is sent. The river erosion control office 21 and the municipal office disaster countermeasures. The headquarters 22 is provided with the most detailed information (level 1 information), and the sabo control department 25 of the country / prefecture and the fire department 26 of the country / prefecture exclude unnecessary information (level 2 information). The data is processed so that the voluntary disaster prevention organization 24 and the residents 27 can be provided with information (level 3 information) excluding unnecessary information.

When the server 4a installed in the disaster prevention information providing site 23 receives information from each administrative agency through the Internet, the attribute of the request information and the called party are determined and the called party is called. Level information.

In this way, by changing the disclosure level of information depending on the other party, unnecessary transmission of information is avoided,
By transmitting only the information that is truly necessary for the other party in an easy-to-understand manner, each institution or individual can make an accurate and prompt decision without being swayed by extraneous information.

Next, the flow of information will be described with reference to FIGS. 2 and 3.
Will be described with reference to.

FIG. 2 is a sequence diagram showing the flow of information in the normal state, and FIG. 3 is a sequence diagram showing the flow of information in the state where the occurrence of a sediment disaster is predicted.

First, a rain gauge 1a provided at each observation point_i

・) Is sent to the river erosion control office 21 by wire or wirelessly.
Reliable 211, these measurement data, river erosion control work
The terminal 2a installed in the office 21 is stored in the database 2b.
It

Further, the rain gauge 1d ₁ (l = 1, 2, ...) Originally installed by the municipal office transmits the measurement data a _i to the municipal office disaster countermeasures headquarters 22 by wire or wirelessly, 218, The data is stored in the database 3b of the terminal 3a installed in the disaster response headquarters 22 of the municipal office.

The terminal 3a installed in the disaster response headquarters 22 of the municipal office and the terminal 2a installed in the river sabo construction office 21 collect these measurement data from the terminal 2a installed in the river sabo construction office 21. The data is transmitted to the server 4a installed in the disaster prevention information providing site 23 via the Internet together with the data of the snake curve data E, the landslide disaster danger point F, and the condition G of the erosion control facility that are stored in the database 2b in advance 212.

The server 4a installed on the disaster prevention information providing site 23 combines the rainfall data received from the river sabo construction office 21 and the municipal government disaster countermeasures headquarters 22 with the geographic data stored in advance, and is shown in FIG. As shown, the present rainfall amount at each observation point (one-hour rainfall amount, cumulative rainfall amount from the beginning of rainfall), change over time, snake curve, and further, for example, is processed as rainfall amount prediction data in a 2.5 km mesh. That is, when a measurement point is plotted on a topographic map and the measurement point is clicked, the current rainfall (1 hour rainfall and cumulative rainfall from the beginning) at that point and the change over time can be displayed. The figure is divided into, for example, a 2.5 km square mesh, and when any section is clicked, it is processed as data so that future rainfall prediction in that section can be viewed.

These data are the rainfall data A ', which is a rainfall condition data calling signal 251 from the sabo department 25 of the country / prefecture, the rainfall condition calling signal 221 from the terminal 3a installed in the disaster countermeasure headquarters 22 of the municipal office, the country.・ A rainfall status call signal 261 from the prefecture fire department 26, and a call signal 2 from the mobile terminal 7 owned by the members of the voluntary disaster prevention organization 24
41 and the call signal 271 from the personal computer of the resident, it is transmitted to each terminal or personal computer via the Internet and can be browsed from each terminal or personal computer (213, 214, 262, 242, 272).

Here, the processed rainfall data transmitted by calling uses the layer function of geographical information, and the disclosure level is changed according to the destination, that is, it is installed in the disaster countermeasure headquarters 22 of the municipal office. When sending it to the terminal 3a, it will be published together with the topographic map showing each house in the private house in which personal information such as the name of the owner is displayed, but at the level of sending to the personal computer of the residents or displayed on the CATV, The display level is different from that in the case of transmitting to the terminal 3a installed in the disaster countermeasure headquarters 22 of the municipal office because the personal information is displayed so that one house is displayed.

FIG. 8 shows an example of the rainfall amount and geographical information displayed on the terminal 2a installed in the river sabo office 21, the terminal 3a installed in the disaster countermeasure headquarters 22 of the municipal office, and the CATV of the residents 27.

As a result, it is possible to transmit appropriate rainfall information to the administrative agencies and residents while avoiding disclosing unnecessary information.

Further, in the server 4a installed at the disaster prevention information providing site 23, the rainfall data, the geographical data and the snake curve data E are combined and processed as data indicating the possibility of a landslide disaster. That is, when a measurement point is plotted on the topographic map and the measurement point is clicked, the data is processed so that the snake curve at that point is displayed (snake curve display data) (see FIG. 6).

The snake curve display data E'indicating the possibility of sediment-related disasters by combining rainfall data, geographical data and snake curve data E is the rainfall status data call signal 251 from the national and prefectural erosion control department 25, the municipal office disaster. A rain condition calling signal 221 from the terminal 3a installed in the countermeasure headquarters 22 is transmitted from the server 4a to each terminal via the Internet and can be browsed by a web browser from each terminal (213, 214).

As described above, by displaying the rainfall situation as the snake curve display data E ', it is possible to visually grasp the possibility of a sediment-related disaster due to rainfall, and thus it is possible to intuitively determine the correspondence.

Like the rainfall data A ′, the snake curve display data E ′ can be called from the fire department 26 of the country / prefecture, the mobile terminal 7 owned by the members of the voluntary disaster prevention organization, and the personal computer from the residents 27. However, according to the actual situation in each local government, it may not be called from the personal computer of the resident 27.

Further, the server 4a installed at the disaster prevention information providing site 23 uses the rainfall situation data calling signal 251 from the sabo control department 25 of the country / prefecture to collect the data of the landslide disaster danger point F and the situation G of the erosion control equipment. When the rain condition calling signal 221 is received from the terminal 3a installed in the disaster countermeasures headquarters 22 of the municipal office, the rain condition calling signal 221 is transmitted to each terminal via the Internet as it is (213, 214), and each terminal uses a web browser to send these data. Can be viewed.

Next, the flow of information in a state where a sediment disaster is predicted will be described with reference to FIG.

In the database 3b of the terminal 3a installed in the disaster countermeasure headquarters 22 of the municipal office, the evacuation site status 22a showing the location of the evacuation site where the residents should evacuate in the event of disaster and the acceptance system, and the evacuation of each evacuation site The data of the evacuees 22b to be evacuated to the place, the evacuation route 22c, and the stockpiling status 22d of the evacuation site are stored in advance.

Furthermore, when a sediment disaster actually occurs,
Based on the information sent to the disaster countermeasures head office 22 of the municipal office, the data of the injured person, the missing person, etc. 22e due to the sediment-related disaster and the data of the people who have successfully evacuated are stored in the database 3b of the terminal 3a installed in the disaster headquarters. Stored in.

The terminal 3a installed in the disaster response headquarters 22 of the municipal office collects these data (22a, 22b, 22).

16), the database 4 of the server 4a installed here
Store in b.

Further, the server 4a installed at the disaster prevention information providing site 23, the evacuation site status 22a, the evacuees 22b who should evacuate to the evacuation site, the evacuation route 22c, the data of the stockpiling status 22d of the evacuation site, and The data of the injured / missing person 22e can be used for the country /
The information is transmitted to the terminal of the erase department defense station 26 in the prefecture (217).

Further, the server 4a installed in the disaster prevention information providing site 23 provides the data of the injured person / missing person 22e to the injured person data call signal 243 from the portable terminal 7 of the member of the voluntary disaster prevention organization 24, Alternatively, an injured person data call signal 273 from the personal computer of the inhabitant is transmitted to the portable terminal 7 of the member of the voluntary disaster prevention organization 24 or the personal computer of the inhabitant (244, 274).

Here, the disclosure level of the information of the injured person / missing person 22e differs depending on the other party who called the information. That is, the injured / missing person 22e to be transmitted to the terminal 3a installed in the disaster response headquarters 22 of the municipal office
All information, including address and name, will be disclosed, but only the name will be disclosed at the level of sending to residents' personal computers.

As a result, it is possible to transmit appropriate information that is easy to understand to residents while avoiding disclosing unnecessary information.

In the present embodiment, the data of the evacuation site status 22a, the evacuees 22b who should evacuate to the evacuation site, the evacuation route 22c, and the stockpiling status 22d of the evacuation site are carried by the members of the voluntary disaster prevention organization 24. The data cannot be sent to the terminal 7 or the personal computer of the inhabitants, but these data can be sent to the mobile terminal 7 of the members of the voluntary disaster prevention organization 24 according to the entity of each local government. good. Further, these data may be transmitted to a personal computer of a resident in response to a call signal from the resident.

Next, in a situation where a sediment-related disaster is predicted, the precursory phenomenon 24a such as a rock fall or a rapid decrease in stream water is
Information by telephone from residents or voluntary disaster prevention organization 2
It is temporarily stored in the database 3b of the terminal 3a installed in the disaster response headquarters 22 of the municipal office by transmission 248 from the mobile terminal 7 of the member of 4 and is installed in the disaster prevention information providing site 23 from the terminal 3a via the Internet 11. It is transmitted to the server 4a 226 and stored in the database 4b of the server 4a installed in the disaster prevention information providing site 23.

Here, the mobile terminal 7 possessed by the members of the voluntary disaster prevention organization 24 has the functions of GPS, mobile phone, and digital camera, and from this mobile terminal 7, the symptom information together with the photo information and the position information. Can be transmitted to the terminal 3a installed in the disaster response headquarters 22 of the municipal office (248).

The precursory phenomenon information sent to the server 4a installed in the disaster prevention information providing site 23 is combined with the geographic information in the server 4a, and the precursory information is reported on the topographic map displayed on the screen of the terminal. The location is indicated by a dot, and the details are displayed by clicking the location.

The server 4a installed in the disaster prevention information providing site 23 automatically transmits the precursor phenomenon information processed in this way to the erosion control department 25 of the country / prefecture and the river erosion control office 21 via the Internet. Yes (231, 23

Here, the processed precursory phenomenon transmitted by calling uses the layer function of geographical information and changes the disclosure level according to the destination. That is, when sending to the terminal 3a installed in the disaster countermeasures headquarters 22 of the municipal office, it is disclosed together with the topographic map showing the individual houses in the state in which personal information such as the name of the owner is displayed, but it is a voluntary disaster prevention organization. At the level of transmitting to the mobile terminal 7 of the members of 24 and the personal computer of the inhabitants 27, the topographic maps are displayed so that not one house can be displayed, so the disclosure levels of both are different.

As a result, it is possible to transmit appropriate landslide disaster-related information that is easy to understand to administrative agencies and residents while avoiding disclosing unnecessary information.

When a precursory phenomenon is reported, it is necessary to set up an evacuation center and guide residents to the evacuation center. Therefore, the server 4a installed at the disaster prevention information providing site 23 sends a signal prompting that to the disaster prevention headquarters of the municipal office. It transmits to the terminal 3a installed in 22 via the internet. The disaster response headquarters 22 of the municipal office establishes an evacuation shelter and the terminals 7 of the members of the voluntary disaster prevention organization 24 via the Internet.

For 7, not only can it be displayed on the computer owned by residents through the Internet, but
It can be displayed on the CATV of each inhabitant through the station and the CATV broadcasting network.

Subsequently, the rainfall data is matched with the snake curve (ST52). As a result, if the rainfall does not exceed the caution line (ST53), it is further checked whether there is a precursory phenomenon (ST53). If there is a precursory phenomenon, a request for voluntary evacuation and establishment of a shelter (ST55) and voluntary evacuation are carried out. Prompt the evacuation center guidance (ST56) to the residents who do this to the disaster response headquarters 22 of the municipal office.

If the rainfall exceeds the caution line (ST53), it is further checked whether it exceeds the caution line (ST57), and if it does not exceed the caution line, it is checked whether there is a precursor phenomenon ( ST54),
If there is a precursory phenomenon, a request for voluntary evacuation and establishment of an evacuation center (ST55) and evacuation center guidance for residents who voluntarily evacuate (S
T56) is urged to the municipal office disaster countermeasures headquarters 22.

If it exceeds the warning line (ST5
7), CTI and CATV are used to request voluntary evacuation or give evacuation advice / instructions to residents (ST58).

Next, a function of limiting the disclosure level to the disclosure level according to the other party to whom the information is transmitted will be described with reference to FIGS.
