Description

[Technical field]

[0001] The present invention relates to a disaster prevention system, and more particularly to a disaster prevention system that supports the issuance decisions of local government officials based on past issuance information. [Background technology]

[0002] [Prior Art] Local government officials issue evacuation information to call on residents to evacuate, etc., regarding disaster prevention, and disaster prevention systems are used to execute these announcements. In conventional disaster prevention systems, the system proposes issuing warnings to local government officials based on meteorological and river information for the monitored area, and the local government officials then issue the warnings to the target area. The "warning information" is what local government officials use to make decisions about issuing warnings. The announcement information includes the time when the system proposes to issue the announcement, the time when local government officials should execute the announcement, the name of the area for which the announcement is to be issued, and the content of the announcement (announcement message) to be transmitted to residents.

[0003] A conventional disaster prevention system includes a notice processing device, a notice desk, a transmitting device, and a receiving device. The announcement processing device monitors meteorological and river information for the monitored area, and when the change exceeds a specific situation (threshold), outputs announcement information to the announcement desk to prompt the announcement, and when a local government official inputs an instruction to output an announcement message calling on residents to evacuate, etc. based on the announcement information from the announcement desk, the transmitting device transmits the announcement message to a remote receiving device for local residents. For example, a threshold value of alert level 3 or higher is used for the specific situation in the above.

[0004] [Related Technology] In addition, related prior art includes JP 2019-176223 A "Wireless Communication System" (Patent Document 1) and JP 2016-143379 A "Wireless Communication System" (Patent Document 2).

[0005] Patent Document 1 describes a disaster prevention radio system for issuing simultaneous commands. Patent Document 2 describes a disaster prevention radio system that displays a warning to check the safety of people in an emergency. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2019-176223 A [Patent Document 2] JP 2016-143379 A Summary of the Invention [Problem to be solved by the invention]

[0007] However, with conventional disaster prevention systems, it was difficult for local government officials to issue evacuation orders and other orders at the appropriate time depending on the disaster situation, and there was a problem that orders were sometimes issued too early or too late, making it impossible to evacuate residents properly.

[0008] Furthermore, Patent Documents 1 and 2 do not describe a configuration in which local government officials issue warnings at an appropriate time by referring to similar meteorological or river information from past warning information for areas similar to the area being monitored.

[0009] The present invention has been made in consideration of the above-mentioned situation, and aims to provide a disaster prevention system that allows local government officials to issue warnings at the appropriate time by referring to similar meteorological or river information from past warning information for areas similar to the monitored area. [Means for solving the problem]

[0010] The present invention, which aims to solve the problems of the above-mentioned conventional examples, is a disaster prevention system that supports the issuance decisions of local government officials, and is equipped with an issuance processing device that inputs regional information on meteorological information, river information, topographical information and hazard map information for monitored and non-monitored areas, and outputs issuance information for monitored areas to an issuance desk used by local government officials, and is characterized in that the issuance processing device aggregates regional information for non-monitored areas that have topographical information similar to the topographical information of the monitored areas, obtains past issuance information from the aggregated regional information, compares the meteorological information or river information for the monitored areas with past meteorological information or river information for non-monitored areas in the past issuance information, and outputs issuance information to the issuance desk based on the past issuance information for non-monitored areas that have similar meteorological information or river information for the monitored areas.

[0011] The present invention is characterized in that, in the above-mentioned disaster prevention system, the announcement processing device stores, from among past announcement information, the proposed time when the system proposed to issue an announcement and the implemented time when an announcement was issued by an employee, and outputs the time at which a local government employee should issue the announcement information to the announcement desk based on the proposed time and the implemented time.

[0012] The present invention is characterized in that, in the above-mentioned disaster prevention system, the issuance processing device calculates the amount of change per unit time in meteorological information or river information in the monitored area, calculates and compares the amount of change per unit time with similar meteorological information or river information from the past in non-monitored areas that have similar topographical information, and controls the time at which to issue the issuance information depending on the comparison result.

[0013] The present invention is characterized in that, in the above-mentioned disaster prevention system, when the issuance processing device outputs the time at which the issuance information should be issued, it also outputs to the issuance desk the proposed time used as reference, evaluation information based on the implementation time, and the meteorological information or river information used as reference.

[0014] The present invention is characterized in that, in the above-mentioned disaster prevention system, the issuance processing device divides the nationwide area into tiles, obtains area names of areas consisting of multiple divided tiles that are similar to the topographical information of the monitored area, and outputs the area names to the issuance desk. Effect of the Invention

[0015] According to the present invention, the issuance processing device aggregates regional information for non-monitored areas that have topographical information similar to that of monitored areas, obtains past issuance information from the aggregated regional information, compares weather information or river information for the monitored areas with past weather information or river information for non-monitored areas in the past issuance information, and outputs issuance information to the issuance desk based on past issuance information for non-monitored areas that have similar weather information or river information for the monitored areas, thereby providing a disaster prevention system that enables local government officials to issue announcements at the appropriate time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. [Outline of the embodiment] In a disaster prevention system (this system) relating to an embodiment of the present invention, an issuance processing device aggregates regional information for non-monitored areas that have topographical information similar to that of monitored areas, obtains past issuance information from the aggregated regional information, compares weather information or river information for the monitored areas with past weather information or river information for non-monitored areas in the past issuance information, and outputs evacuation announcement information to a issuing desk based on the past issuance information for non-monitored areas that have similar weather information or river information to the monitored areas, allowing local government officials to issue evacuation announcements at the appropriate time.

[0018] [This system: Figure 1] This system will be described with reference to Figure 1. Figure 1 is a schematic diagram of the configuration of this system. As shown in FIG. 1, the system includes a call processing device 1, a call console 2, a transmitting device 3, and a receiving device 4.

[0019] The announcement processing device 1 is connected to an announcement desk 2 and also to a transmitting device 3, and the transmitting device 3 connects to a receiving device 4 via wireless communication to transmit the announcement content (announcement message), and the receiving device 4 receives the announcement content and outputs voice or text, or both. Although there are actually a plurality of receiving devices 4, only one is shown in FIG. 1 for ease of explanation.

[0020] [Command Processing Device 1: Figure 2] Next, the announcement processing device 1 will be described with reference to Fig. 2. Fig. 2 is a schematic diagram showing the configuration of the announcement processing device. As shown in FIG. 2, the announcement processing device 1 is a computer processing device, and is equipped with a control unit 11, a memory unit 12, and an interface unit 13. The control unit 11 executes a processing program stored in the memory unit 12, thereby realizing the functions described below. The interface unit 13 is an interface unit that connects the issuing desk 2 and the transmitting device 3 .

[0021] The memory unit 12 further includes multiple storage devices, such as a hazard map information memory unit 121, a river information memory unit 122, a meteorological information memory unit 123, a topographical information memory unit 124, an issuance judgment information memory unit 125, and an evaluation information memory unit 126.

[0022] The hazard map information storage unit 121 stores hazard map information issued by the Geospatial Information Authority of Japan. The hazard map information indicates potential disaster risks for each region. The river information storage unit 122 stores information on current and past rivers throughout the country. The weather information storage unit 123 stores current and past weather information for each region. In addition, the weather information issued by the Japan Meteorological Agency is associated with an alert level; for example, a "heavy rain warning (landslide)" is alert level 3, and a "landslide alert information" is alert level 4.

[0023] The topographical information storage unit 124 stores topographical information of regions consisting of areas divided into tiles. A tile is defined by latitude and longitude, and a plurality of tiles are collected to form a region, and the region is given a region name. Moreover, the topographical information storage unit 124 stores areas with similar topography in association with each other, and aggregates the similar areas.

[0024] The issuance judgment information storage unit 125 stores past issuance information such as the proposed issuance time when the system previously proposed issuance, the issuance implementation time when local government officials issued the issuance, the issuance content, and the name of the area for which the issuance was made, as well as issuance judgment information such as meteorological information and river information at the time of issuance.

[0025] The evaluation information storage unit 126 stores evaluation information that evaluates the appropriateness of the proposed issuance time and the actual issuance time based on meteorological information and river information at the time of issuance. The evaluation information will be described later. The specific processing of the control unit 11 using the information in each of the above-mentioned storage units will be described later.

[0026] [Order Desk 2] The announcement desk 2 displays the announcement information output (transmitted) from the announcement processing device 1, and local government officials make announcement decisions based on the announcement information, input announcement instructions to issue the announcement, and output the announcement content to the transmission device 3.

[0027] [Transmitter 3] The transmitting device 3 transmits the announcement contents to the receiving device 4 in accordance with an announcement instruction from the announcement desk 2 . [Receiver 4] The receiving device 4 receives the contents of the announcement from the transmitting device 3 and outputs them as a display or as a sound.

[0028] [System processing: Figure 3] Next, the processing in this system will be described with reference to Fig. 3. Fig. 3 is a schematic flow diagram of the processing in this system. In this system, as shown in Fig. 3, the control unit 11 of the announcement processing device 1 extracts similar areas from the area information storage unit 124, associates the similarities between the areas, and stores them (S1). Similar areas are aggregated based on this association.

[0029] Furthermore, the control unit 11 acquires past announcement determination information from the announcement determination information storage unit 125, generates evaluation information on the appropriateness of announcement, and stores it in the evaluation information storage unit 126 (S2).

[0030] Specifically, the control unit 11 acquires from the issuance judgment information memory unit 125 the name of the area where the announcement was made, the announcement content (issuance message), the time when the system proposed to issue the announcement in the past (proposed issuance time), the time when the announcement was actually issued by local government officials (implemented issuance time), the meteorological information at that time, and the river information at that time, and evaluates the appropriateness of the proposed issuance time and the implemented issuance time from the meteorological information and river information.

[0031] The appropriateness of the warning is determined by judging whether the time was too early, appropriate, or too late. Specifically, the amount of change per unit time in the weather and the amount of change per unit time in the river water level at the time of past warning is calculated, and the appropriateness is judged based on the timing of the warning in relation to the amount of change (proposed time of issuance, actual time of issuance). Based on this evaluation information, the time when the system should have proposed issuing the order (the appropriate time to propose issuing the order) and the time when the staff should have issued the order (the appropriate time to implement the order) can be calculated.

[0032] The control unit 11 also determines whether the current weather information and river information for the monitoring area exceed a specific threshold value (a specific rainfall value, a specific river water level value) corresponding to the hazard map information (S3), and if not exceeded (No), repeats the determination process S3. The control unit 11 may periodically deliver the current weather information or river information for the monitoring area to the receiving device 4 even before the issuance of a warning.

[0033] If the specific threshold is exceeded (Yes), the control unit 11 proceeds to the announcement process (S4) and displays and outputs the announcement information on the announcement desk 2 (S5). This announcement information includes the announcement time proposed by the system, the time when the announcement should be issued by the local government staff, the name of the area to which the announcement is to be issued, and the announcement message.

[0034] Then, the control unit 11 determines whether or not an issuance instruction has been input from the issuing desk 2 (S6), and if an issuance instruction has not been input (No), the determination process S6 is repeated, and if an issuance instruction has been input (Yes), the control unit 11 transmits an issuance message to the receiving device 4 via the transmitting device 3 (S7).

[0035] [Order processing: Figure 4] Next, the announcement process S4 will be specifically described with reference to Fig. 4. Fig. 4 is a specific processing flow diagram of the announcement process. When the issuance process S4 is started, as shown in FIG. 4, the control unit 11 searches the area information storage unit 124 for areas similar to the area to be monitored (areas not to be monitored) (S11).

[0036] Furthermore, the control unit 11 acquires previously issued warning determination information for similar areas searched for in process S11 from the warning determination information storage unit 125 (S12), and acquires river information and weather information at the time of past issuance in the warning determination information for a specific period by referring to the river information storage unit 122 and the weather information storage unit 123 (S13).

[0037] Then, the control unit 11 calculates the amount of change per unit time of past weather information or river information for the acquired specific period (past amount of change) (S14), calculates the amount of change per unit time of current weather information or river information in the monitored area (current amount of change) (S15), and extracts issuance judgment information having a past amount of change similar to the current amount of change (S16).

[0038] Next, the control unit 11 acquires evaluation information corresponding to the issuance determination information from the evaluation information storage 126 (S17). The control unit 11 outputs and displays on the issuing desk 2 the current proposed issuing time and the time to issue, based on the past proposed issuing time and the issuing implementation time in the evaluation information, as well as past meteorological or river information that was used as the basis for the decision (S18). The time to issue is calculated using the following formula. Time to issue = current proposed time of issue + (past implementation time of issue - past proposed valid time of issue) The announcement information may also include current weather information and river information for the area being monitored.

[0039] Then, when the control unit 11 receives issuance information from a local government employee at the issuance desk 2, it issues the issuance (S19), stores the issuance information in the issuance determination information storage unit 125, outputs an issuance message to the transmitting device 3, and the issuance message is transmitted to the receiving device 4 (S7).

[0040] In this way, when local government officials send issuance information based on current weather information or river information, the issuance processing device 1 displays the proposed issuance time and the time to issue the announcement on the issuance desk 2 by referring to similar weather information or river information in similar areas, so that local government officials can make an appropriate decision on whether to issue the announcement.

[0041] [Effects of the embodiment] According to this system, the issuance processing device 1 aggregates regional information for non-monitored areas that have topographical information similar to that of monitored areas, obtains past issuance information from the aggregated regional information, compares meteorological information or river information for the monitored areas with past meteorological information or river information for non-monitored areas in the past issuance information, and outputs issuance information to the issuance desk 2 based on the past issuance information for non-monitored areas that have similar meteorological information or river information to the monitored areas, thereby having the effect of enabling local government officials to issue announcements at the appropriate time. [Industrial Applicability]

[0042] The present invention is suitable for a disaster prevention system that allows local government officials to issue warnings at the appropriate time by referring to similar meteorological or river information from past warning information for areas similar to the monitored area.
