The third communication function unit 130 communicates with a database server (abbreviated as DBS in the figure) 30 that stores information such as NEXCO (registered trademark) and road information held by prefectures.

The fourth communication function unit 140 communicates with a database server (abbreviated as DBS in the figure) 40 that stores the position information of a communication terminal such as a personal smartphone owned by a mobile phone company, for example.

Further, in the water stable supply system 100 of the first embodiment, the water outage area extraction function unit 210, the evacuation center extraction function unit 220, the traffic route extraction function unit 230, the water supply amount extraction function unit 240, the water intake location extraction function unit 310, It includes a water supply information extraction function unit 410, a screen display function unit 510, and a related party information transmission function unit 520.

The water outage area extraction function unit 210 is based on information such as emergency shutoff valve closure, water pipe flow velocity, and flow rate obtained from the database server 10 owned by the waterworks bureau or the like via the first communication function unit 110. And extract.

The evacuation center extraction function unit 220 has hazard map information obtained from the database server 20 owned by the Ministry of Land, Infrastructure, Transport and Tourism via the second communication function unit 120, and information on the water outage area extracted by the water outage area extraction function unit 210. Based on, the shelters in the water outage area are extracted. Basically, multiple hazard maps are superimposed to narrow down the evacuation centers.

The traffic route extraction function unit 230 has NEXCO (registered trademark), road information obtained from the database server 30 owned by the prefecture via the third communication function unit 130, and water outage extracted by the water outage area extraction function unit 210. Based on the information of the area, the currently passable route in the water outage area is extracted. In addition to NEXCO (registered trademark), information obtained in cooperation with VICS (registered trademark) (Vehicle Information and communication System) is screened to extract passable routes.

The water supply amount extraction function unit 240 obtains the position information of the personal communication terminal obtained from the database server 40 owned by the mobile phone company or the like via the fourth communication function unit 140, and is extracted by the evacuation center extraction function unit 220. Based on the information on the shelters provided, the population density of the shelters and the required amount of water supply according to the population density are calculated.

The water intake location extraction function unit 310 can take water and pass through based on the information of the water outage area extracted by the water outage area extraction function unit 210 and the passable route extracted by the passage route extraction function unit 230. Extract candidates for location.

The water supply information extraction function unit 410 includes a water outage area extracted by the water outage area extraction function unit 210, an evacuation center extracted by the evacuation center extraction function unit 220, and a passable route extracted by the passage route extraction function unit 230. Based on each information of the water supply amount calculated by the water supply amount extraction function unit 240 and the water intake location extracted by the water intake location extraction function unit 310, the water supply amount to the evacuation center and the water supply vehicle evacuate via the water intake location. The passable route to the place is specified and the result is output to the outside as water supply information.

The screen display function unit 510 displays the result obtained by the water supply information extraction function unit 410 on the screen so that it can be visually recognized by the human eye.

The related party information transmission function unit 520 transmits information to the related party in which the result obtained by the water supply information extraction function unit 410 is registered in advance.

Next, the operation of each part will be described.
The water outage area extraction function unit 210 extracts the water outage area and the non-water outage area from the emergency shutoff valve information, the flow rate, the flow velocity information, etc. provided from the database server 10 owned by the waterworks bureau or the like. As a result, the area where the water is cut off becomes the area where water should be supplied by the stable water supply system 100. Further, although the water cutoff area extraction function unit 210 is basically an automatic calculation, manual input is also possible. This is to reflect reliable water outage information from local water bureau staff or local government officials in the system.

The evacuation center extraction function unit 220 screens information based on the hazard map information provided by the database server 20 owned by the Ministry of Land, Infrastructure, Transport and Tourism, private companies, etc., and extracts evacuation center candidates. In addition to this, the accuracy of the evacuation center candidates extracted by the evacuation center extraction function unit 220 is verified and corrected from the population density distribution information based on the information from the personal communication terminal handled by the water supply amount extraction function unit 240. conduct.

The passage route extraction function unit 230 grasps the passable roads based on the road operation information obtained from the database server 30 owned by NEXCO (registered trademark), prefectures, and the like. Since the road information includes VICS (registered trademark) and the like, the traffic route extraction function unit 230 performs information fusion or screening.

The water supply amount extraction function unit 240 obtains the location information of the personal communication terminal from the database server 40 owned by the mobile phone company, calculates the population density in the evacuation center based on this location information, and uses the calculated population density as the calculated population density. Calculate the required water supply according to the situation. In addition, the calculated population density is handed over to the evacuation center extraction function unit 220.

The water supply amount extraction function unit 240 simply calculates the required water supply amount according to the population density distribution, regardless of the presence / absence of a water outage area and the presence / absence of an evacuation center. Further, the water supply amount extraction function unit 240 calculates the population density in the evacuation center based on the periodic location information from the mobile phone company or the like as described above, and the communication terminal is used for the calculation of the population density in that case. Personal information will not be handled. That is, since the mobile phone company or the like knows which individual's communication terminal is connected to the base station of which city, town or village in which prefecture, it is possible to acquire the position information of the communication terminal.

As for communication terminals, one base station covers a radius of several kilometers, so the number of communication terminals existing in the area is the population density distribution. However, the 5th generation mobile communication (hereinafter referred to as 5G), which has been attracting attention in recent years, uses a higher frequency band than the current 4G. As the frequency band of wireless communication radio waves increases, high-speed communication becomes possible, but conversely, the communicable distance becomes shorter. Therefore, in 5G, the range covered by one base station is smaller than the present, and it can be expected that the population density can be calculated with higher accuracy.

The water intake location extraction function unit 310 identifies an area where water can be taken without water outage based on the information from the water outage area extraction function unit 210, and is based on the passable road information from the traffic route extraction function unit 230. , Extract candidates for water intake locations that are accessible and passable.

The water supply information extraction function unit 410 identifies an area that requires water supply due to a water outage from the information of the water outage area extraction function unit 210, and calculates an evacuation center corresponding to the water outage area from the information of the evacuation center extraction function unit 220. .. Then, by superimposing the information from the passage route extraction function unit 230, the passable passage route from the water supply vehicle to the evacuation center where water should be supplied is calculated. At that time, the priority of the evacuation center to be supplied with water is calculated from the information of the water supply amount extraction function unit 240. Finally, from the information of the water intake location extraction function unit 310, a place where water can be taken is assigned in the middle of the evacuation center to be visited, and a water supply route that can be patrolled with a single stroke is calculated and output.

The screen display function unit 510 displays the result calculated by the water supply information extraction function unit 410 on the screen so that a human can visually recognize it. That is, on this display screen, it is displayed on which route one water truck supplies water to the evacuation shelter in which water outage area. It also displays information such as how many hours a water truck comes around at one evacuation center.

The related party information transmission function unit 520 transmits information to the related party the result calculated by the water supply information extraction function unit 410. In this case, there may be a plurality of related parties, and it is expected that the required information will be different for each related party. Therefore, the related party information transmission function unit 520 prepares a communication protocol, a distribution format, and an electronic file format according to the information distribution destination.

As described above, according to the stable water supply system of the first embodiment, the social capital of Japan such as the Waterworks Bureau, the Ministry of Land, Infrastructure, Transport and Tourism, NEXCO (registered trademark), prefectures, and mobile phone companies is formed in the information and communication field. By coordinating with information held by local governments and companies, and by utilizing information sent from disaster victims at the same time, the amount of water intake required to secure the amount of water supply required at evacuation centers in water outage areas, and the amount of water intake required. It is possible to automatically and surely determine the water supply route for the water supply vehicle to travel efficiently with a small number of personnel. This has the effect of making it possible to stably supply water to evacuation shelters in areas where water is cut off in the event of a disaster.

Embodiment 2.
FIG. 2 is a configuration diagram showing a stable water supply system according to the second embodiment of the present application.

In the stable water supply system according to the second embodiment, the homepage function unit 610 for disaster countermeasures is added to the configuration of the stable water supply system shown in FIG.

The disaster countermeasure homepage function unit 610 provides water supply information to a communication terminal owned by the disaster victim or a personal computer (hereinafter referred to as a PC) temporarily installed in an evacuation center. It also provides a screen where disaster victims can enter local information.

Further, the disaster countermeasure homepage function unit 610 cooperates with the water supply information extraction function unit 410, the water outage area extraction function unit 210, the evacuation center extraction function unit 220, and the traffic route extraction function unit 230, and provides water outage information. The database server 10 for storing hazard map information, the database server 20 for storing hazard map information, and the database server 30 for storing road information are configured to cooperate with each other. Information linkage in this case will be carried out by utilizing the existing information processing technology.

Next, the operation in the second embodiment will be described.
The homepage function unit 610 for disaster countermeasures provides water supply information for communication terminals owned by disaster victims or PCs temporarily installed in evacuation shelters. That is, the homepage function unit 610 for disaster countermeasures provides information on when and how much water is delivered to each evacuation center based on the result calculated by the water supply information extraction function unit 410. It also provides information on the next water supply at a certain evacuation center.

Further, the homepage function unit 610 for disaster countermeasures provides information on the place where the water truck can reach when the road is cut off due to the collapse of a building or the like in the water supply route to the evacuation center. This road disruption information is output based on the information input by the disaster victim, which will be described later. With this mechanism, when the road is cut off, both the victim and the water truck can share information on the contact points of each other, which enables stable water supply.

In addition, the homepage function unit 610 for disaster countermeasures distributes an input screen of the local situation to the communication terminal and the PC of the disaster victim. When the victim inputs the surrounding conditions such as water outage, power outage, and road condition on the screen, the input information is accumulated in the disaster countermeasure homepage function unit 610. The accumulated information is reflected in the water outage area extraction function unit 210, the evacuation center extraction function unit 220, and the traffic route extraction function unit 230, and becomes a more accurate water supply information extraction function unit 410.

That is, the more detailed information on the site is input to the disaster countermeasure homepage function unit 610, the more accurate the water stable supply system becomes. In addition, the more evacuation centers that have entered detailed local information, the more accurate the water supply can be received.

The local information stored in the disaster countermeasure homepage function unit 610 is transmitted to the database server 10 that stores water outage information, the database server 20 that stores hazard map information, and the database server 30 that stores road information. The database server 10 for accumulating water outage information, the database server 20 for accumulating hazard map information, and the database server 30 for accumulating road information feed back the accumulated data from the disaster countermeasure homepage function unit 610 as the result of this disaster. The accuracy can be improved for the next time.

For example, the database server 20 that stores hazard map information also provides information on shelters in the event of a disaster. By feeding back this information to the shelter of the accumulated data that actually had a disaster, it is possible to verify whether the predicted shelter was correct and whether there was another candidate for a better shelter.

Immediately after the occurrence of a large-scale disaster such as an earthquake, communication for local governments that handle social infrastructure such as water, gas, and electricity will be prioritized as stipulated by law. For this reason, the communication function for the disaster victim is greatly restricted, and even if the screen is delivered to the communication terminal of the disaster victim, a large delay occurs. In order to avoid this, information is distributed and information is acquired using the PC installed in each evacuation center as a representative terminal.

Specifically, if the communication speed (Internet access response time) set by the disaster countermeasure homepage function unit 610 or less, refrain from voluntarily sending information to the communication terminal of the disaster victim or the PC of the evacuation center, and refrain from voluntarily sending information to each evacuation center. Information is distributed and information is acquired by allowing only access from the PC.

There is also access to the homepage function unit 610 for disaster countermeasures from the communication terminal of the victim. In this case, the access point is accessed in the order of the communication terminal → the access point of the mobile phone company → the access network → the homepage function unit 610 for disaster countermeasures via the core network. Since mobile phone companies have information about users' communication terminals, they will utilize this information. The homepage function unit 610 for disaster countermeasures is provided with a firewall function, and access from the communication terminal is restricted (not permitted) when the communication speed becomes lower than the set communication speed.

As described above, according to the stable water supply system of the second embodiment, the effect of the first embodiment can be obtained by further adding the homepage function unit 610 for disaster countermeasures to the configuration of the first embodiment. In addition, as the number of inputting detailed information on the site to the disaster countermeasure homepage function unit 610 increases, it is possible to supply water to the evacuation center with high accuracy. Furthermore, even if access from mobile terminals is restricted and the communication function cannot be fully exerted, it is possible to obtain detailed local information from the disaster countermeasure homepage function unit 610 and maintain highly accurate water supply. The effect is obtained.

Embodiment 3.
FIG. 3 is a configuration diagram showing a stable water supply system according to the third embodiment of the present application.

The stable water supply system of the third embodiment has a normal water leakage record database (abbreviated as DB in the figure) 710, a normal operation operation history database (abbreviated as DB in the figure) 720, and a disaster operation history database (DB in the figure). (Omitted) 730, normal water leakage characteristic analysis unit 740, and normal water leakage prediction unit 750.

The normal water leakage record database 710 is a database in which information on past water leakage accidents that actually occurred in normal times is registered and accumulated by the staff of the waterworks municipality. The information on the water leakage accident in this case is, for example, actual information indicating the date and time when the water leakage accident occurred, the area where the water leakage accident occurred, the location, and the specific content of the water leakage accident (for example, the degree of cracking of the water pipe). ..

The normal operation history database 720 corresponds to the actual information of water leakage accidents accumulated in the normal water leakage record database 710, and when a water leakage accident occurs in normal times, the staff of the water supply municipality etc. opens and closes the valve and pumps. It is a database that stores the contents of driving operations such as on / off.

The disaster operation history database 730 is a database that collects and accumulates the contents of operation operations such as opening and closing valves and turning pumps on / off by employees of water services municipalities in the event of a disaster from a wide range of areas.

Therefore, in the information of the operation history during a disaster stored in the operation history database 730 during a disaster, the pressure of the water pipe drops significantly in a short time due to a serious accident such as a disconnection or a large rupture of the water pipe during a disaster. However, in order to deal with this, the operation history peculiar to disasters, which is different from normal times, is naturally included, such as opening the valve fully or starting multiple pumps at the same time. However, not only that, but in the event of a disaster, a slight crack may occur in the water pipe, and a slight leak may occur as if the water leak that could occur in normal times was manifested by the disaster. The operation history that seems to be an extension of normal times, such as increasing the opening slightly, is also included at the same time.

Here, the information stored in the above-mentioned normal water leakage record database 710 and normal operation operation history database 720 is, for example, the normal water leakage record in a relatively limited area of each municipality and the corresponding operation history. It is a collection of information on.

On the other hand, the information stored in the disaster driving operation history database 730 is, for example, collected and accumulated as much information as possible about the driving operation history at the time of a disaster in a relatively wide area of each prefecture.

Therefore, when comparing the amount of information stored in the normal operation history database 720 and the amount of information stored in the disaster operation history database 730, the latter has a relatively larger amount of information than the former. It has become.

The normal operation history database 720 and the disaster operation history database 730 may be provided individually with a recording medium such as a hard disk, or may share a recording medium.

The normal water leakage characteristic analysis unit 740 obtains, for example, normal water leakage characteristics based on the normal water leakage information accumulated in the normal water leakage record database 710 and the operation operation history information at that time stored in the normal operation history database 720. It analyzes using artificial intelligence (hereinafter referred to as AI) and outputs the result.

The normal water leakage prediction unit 750 executes analysis using AI based on the information of the operation history such as opening / closing of the valve and on / off of the pump accumulated in the disaster operation history database 730 during normal times. The water leakage characteristics of the above are extracted, the extracted water leakage characteristics are combined with the normal water leakage characteristics obtained as the analysis result of the previous normal water leakage characteristic analysis unit 740, and the result is output as a normal water leakage prediction 760.

Next, the specific operations of the normal water leakage characteristic analysis unit 740 and the normal water leakage prediction unit 750 will be described.

The normal water leakage characteristic analysis unit 740 artificially creates, for example, the normal water leakage characteristic based on the normal water leakage information accumulated in the normal water leakage record database 710 and the operation operation history information at that time stored in the normal operation operation history database 720. Extraction is performed using intelligence (hereinafter referred to as AI (Artificial Intelligence)), and the result is output.

Here, the normal water leakage characteristic indicates a tendency peculiar to water leakage that occurs in normal time. For example, the amount of increase in valve opening compared to the case where water leakage does not occur in normal time, or the drainage output of the pump. The tendency of characteristic changes due to the occurrence of water leakage, such as the amount of increase, is analyzed and extracted.

Subsequently, the normal water leakage prediction unit 750 extracts the normal water leakage characteristics using AI based on the information of the operation history accumulated in the disaster operation history database 730.

As mentioned above, the information on the disaster operation history stored in the disaster operation history database 730 can be roughly divided into the operation history for disaster-specific water leaks that are different from normal times and the leaks that can occur even in normal times. Two types of information on the driving operation history are mixed.

However, when the normal water leakage prediction unit 750 predicts the normal water leakage characteristics, the information on the operation history peculiar to the disaster is peculiar as compared with the normal times, so such information is used to extract the normal water leakage characteristics. It is necessary to exclude and use only the operation history for water leakage that can occur even in normal times.

Therefore, the normal water leakage prediction unit 750 sets a threshold value for determining whether the operation history is for a disaster-specific leak case or the operation history for a normal water leak case, and extracts only the latter information. ..

This point will be described below with reference to the flowchart shown in FIG. In the drawing, the sign S means a processing step.

In general, water leakage that occurs when a water pipe bursts significantly during a disaster tends to cause the pressure of the water pipe to drop significantly in a short time. In order to deal with this, as the operation history at this time, there may be a case where the amount of water supply is increased, for example, the valve is fully opened or a plurality of pumps are started at the same time. When there is such an operation operation history (operation history 1) (step S820), the normal water leakage prediction unit 750 determines that there is a water leakage characteristic (water leakage characteristic 1) peculiar to a disaster (step S870).

In addition, although the pressure of the water pipe is not as short as the former, the change in pressure drop per unit time is large, and there is a disaster-specific operation history (operation history 2) that is different from normal times to deal with it. At the time (step S830), the normal water leakage prediction unit 750 determines that there is a water leakage characteristic (water leakage characteristic 2) peculiar to a disaster (step S880).

On the other hand, when there is an operation history (operation history 3, operation history 4) similar to that in normal times in order to show a tendency similar to that of water leakage that occurs in normal times, such as water leakage due to minute cracks (step S840). , Step S850), the normal water leakage prediction unit 750 determines that there is a normal water leakage characteristic (water leakage characteristic 3, water leakage characteristic 4) (step S890, step S900).

Then, by setting the threshold value Lsh in advance between the discrimination results of the water leakage characteristics 1 and 2 and the water leakage characteristics 3 and 4, the normal water leakage prediction unit 750 can use the information based on the disaster-specific operation history ( Leakage characteristics 1 and 2) are excluded, and only water leakage characteristics (water leakage characteristics 3 and 4) based only on the operation history for water leakage that may occur even in normal times are extracted.
The leak characteristic may be determined by parameters different from the above, such as the same leak amount per unit time but different leak water pressure.

In this way, by patterning the operation history for the size and characteristics of water leakage, pressure changes, etc., and selecting the water leakage characteristics with the preset threshold value Lsh, it is possible to derive the water leakage characteristics that can occur even in normal times. ..

Subsequently, when the normal water leakage prediction unit 750 extracts the normal water leakage characteristics based on the operation operation history information accumulated in the disaster operation history database 730 as described above, the normal water leakage characteristics are described above. Combined with the normal water leakage characteristics extracted by the analysis unit 740, this is output as the normal water leakage prediction 760.

Thereby, based on the normal water leakage prediction 760 obtained as the analysis result of the normal water leakage prediction unit 750, it is possible to confirm whether or not the water leakage actually occurs and take measures. Then, the result of the normal water leakage prediction 760 is fed back to the normal water leakage characteristic analysis unit 740. By doing so, it is possible to improve the extraction performance of the normal water leakage characteristics analyzed by the normal water leakage characteristic analysis unit 740.

That is, in the initial stage, the normal water leakage characteristic analysis unit 740 accumulates the information of the normal water leakage record in a relatively limited area and the corresponding operation history and extracts the water leakage characteristic. The amount of information is relatively small and the accuracy is not very high. However, since the normal water leakage characteristics predicted by the normal water leakage prediction unit 750 are fed back to and added to the normal water leakage characteristic analysis unit 740 as the normal water leakage prediction 760, the normal water leakage characteristics are extracted by the normal water leakage characteristic analysis unit 740. The detection accuracy will gradually increase.

As described above, according to the stable water supply system of the third embodiment, the operation history for water leakage, which is often the case in the event of a disaster, is utilized, and the water leakage characteristics in normal times based on the information are analyzed and extracted by AI. By feeding back the extracted water leakage characteristics to the operation history during normal times, it is possible to obtain the effect that the water leakage characteristics during normal times can be detected accurately with little effort.

Although the present application describes various exemplary embodiments, the various features, embodiments, and functions described in the plurality of embodiments are limited to the application of the particular embodiment.
