Description

The present invention relates to a hazard map system including a sensing unit capable of reliably installing a water level sensor in a place where flooding or inundation occurs.

It is known that there are two types of flooding in which river water overflows to the outside such as embankments: external flooding and inland flooding. Outside flooding is flood damage caused by the rise in the water level of the river itself, and a large amount of water flows into the city area at a high speed, causing flooding of houses and human damage in a short time. In this case, the water that flows in becomes muddy water, and sediment and sludge accumulate even after the flood has subsided, so it takes time to recover.
Inland flooding is flood damage caused by rain that falls in urban areas, and when the amount of rainwater exceeds the treatment capacity of the city, inland flooding occurs. Normally, inland water is drained to rivers by sewer storm drains and pump facilities, but if the facility's capacity cannot keep up with the amount of rain or if the outside water level rises and drainage is not possible, the inland water will not drain well. Buildings, land, roads, etc. are submerged in water. In particular, local heavy rains such as guerrilla rainstorms have occurred frequently in recent years, and the damage caused by inland flooding is increasing.
In recent years, with the frequent occurrence of torrential rains and the progress of urbanization, a large amount of rainwater flows out in a short time and the risk of inland flood damage is increasing.

On the Ministry of Land, Infrastructure, Transport and Tourism hazard map portal site (http://disaportal.gsi.go.jp/index.html), overlapping hazard maps are published as disaster prevention information. In the overlapping hazard map, it is possible to superimpose inundation areas, road information, dangerous places, etc. on maps and aerial photographs, and it is possible to display seamless maps that transcend the boundaries of prefectures and municipalities. .. This hazard map is an information map that displays the range and depth of the predicted flood damage area.

Further, a conventional real-time dynamic flood simulation system described in Patent Document 1 has been proposed, which can provide a flood hazard map corresponding to an actual flood / flood that changes from moment to moment.
In this conventional real-time dynamic flood simulation system, a river information database, a flood source database, a runoff analysis means, a river channel water level prediction means, a breakwater point inflow calculation means, a flood analysis means, and a feedback correction means are used. , Simulation display means and data distribution means that automatically sends map information, address / landmark information, river information about rain and flood hazard map related information from the distribution server, and can be used by the Internet, personal computer communication, and networks. It is automatically delivered from the platform that can.

By the way, the assumed flooding area shown in the hazard map etc. is just the assumed area, and inland flooding may occur in a very short time, so it is necessary to surely install a water level sensor in the place where the flooding occurred. .. However, it is difficult to identify the location where flooding will occur and install a water level sensor at that location. In addition, a means of identifying the location of the flood by performing image analysis using a satellite or the like when the flood occurs is conceivable, but the image analysis of the satellite image is an image comparison between before and after the flood. For this reason, when it occurs in a short time and converges in a short time, such as when it suddenly occurs and settles like inland flooding, the state of inland waters inundation is captured in the images before and after the flooding. In some cases, it was difficult to respond to short-term occurrences. As a result, conventionally, the water level sensor has been installed as shown in FIG. FIG. 25 is a map of an area A consisting of 9 blocks of blocks A-1 to A-9. A lamp line 400 is laid across blocks A-1 to A-3, and the lamp line 400 is located between utility poles 401. It is stretched over. Further, since the water level sensor uses a commercial power source, the water level sensor A is located near the river 402 at a point a between the block A-1 and the block A-2 where the commercial power source from the lamp line 400 can be used. The water level sensor group B is installed at a point b on the road between blocks A-2 and A-3 and blocks A-5 and A-6 where commercial power from the lamp line 400 can be used. A water level sensor was not installed in the submerged frequent occurrence area 403 of the block A-5 because it is not a road and the commercial power source from the lamp line 400 cannot be used. In this way, water level sensors are installed mainly in places where there is water such as rivers and places where flooding is expected due to rainfall due to geographical and structural causes such as underpasses, causing inland flooding. There was a problem that the water level sensor could not be installed reliably in the place where the water level was to be installed.

Therefore, it is an object of the present invention to provide a hazard map system provided with a sensing unit capable of reliably installing a water level sensor in a place where flooding or inundation occurs.

The slave unit ID, which is an identification number, and the position information of the installed point are transmitted to the master unit C or the master unit D to establish communication between each other. Then, when the provided water level sensor detects a significant water level exceeding the specified water level, the slave units CA, CB, and CC have the water level sensor information detected by the water level sensor and the slave unit. The slave unit ID is added to the water level information including the time information when the water level is acquired, and the slave unit ID is sent to the master unit C or the master unit D. After the slave units CA, CB, and CC detect a significant water level, the water level information with an ID is sent to the master unit C or the master unit D at predetermined time intervals.

The control program stored in the ROM 42 is when the slave unit 20 is a slave unit AA, AB, AC, or when the slave unit is BA, BB, BC. , It is different from the case where the slave units CA, CB, and CC are used. In the case of slave units B-A, B-B, BC, the control program in the case of slave units A-A, AB, AC is used to connect the slave units to each other wirelessly such as LAN. A program to connect by closed communication has been added, and if it is a slave unit CA, CB, CC, it is a control when it is a slave unit AA, AB, AC. A program has been added to the program that selects the master unit with the highest electric field strength among a plurality of master units and connects them by wireless closed communication such as LAN.

Next, the configurations of the master units A, B, and C will be described, but since the configurations of the master units are the same, they will be described below as the master unit 30. FIG. 12 shows a functional block diagram showing the configuration of the master unit 30.
As shown in FIG. 12, the master unit 30 includes a microcontroller 31, a wide area communication network communication I / F 32, and a closed area communication network communication I / F 33, and these are connected by a bus.

Then, the CPU 41 transmits the position information with the slave unit ID and the water level information with the slave unit ID received from the slave unit 20 to the information providing unit 12 via the wide area communication network communication I / F32. The power supply device 34 is a power supply device that steps down the commercial power supply to a DC voltage of a predetermined voltage. Further, the power supply device 34 may be composed of a large-capacity capacitor or a secondary battery according to the power consumption capacity instead of the commercial power supply, and a solar panel for charging.

As described above, in the first closed communication network 14A to the third closed communication network 14C, the master units A, B, and C are transmitted from the slave units AA to CC belonging to the closed communication network. When the location information of the installed point with the slave unit ID and the water level information (sensor information + time information) with the slave unit ID are received, each of the master units A, B, and C will be connected to the Internet communication network or public communication network. The position information of the installed point with the received slave unit ID and the water level information with the slave unit ID are sent to the information providing unit 12 via the wide area communication network 13 including the slave unit ID. The information providing unit 12 includes an information distribution server 12a, a data processing server 12b, and a database unit 12c, and the configuration of the information providing unit 12 is shown in FIG. 14A.
In the information providing unit 12 having the configuration shown in FIG. 14A, the data sent from the master units A, B, and C via the wide area communication network 13 is received via the wide area communication network communication I / F12d, and the data is received. It is passed to the data processing server 12b. When the received data is the position information with the slave unit ID, the data processing server 12b associates the position information with the slave unit ID and writes it in the sensor coordinate DB (DB: database) 51 of the database unit 12c. This position information shows the coordinates on the map. In the case of water level information with slave unit ID (sensor information + time information), the database unit 12c associates the water level information with slave unit ID (sensor information + time information) with the slave unit ID and acquisition time together with the current time. It is written in the sensor information DB 52 of. As a result, the water level information (sensor information + time information) detected by the slave units AA to CC sent from the master units A, B, and C is associated with the slave unit ID and the sensor information DB 52.

It includes a map information DB 54 that it holds, and a registrant information DB 55 that stores registrant information for each area that notifies that there is a risk of flooding.
When the information distribution server 12a receives the browsing request, the data processing device 50 provided in the information distribution server 12a creates a real-time hazard map according to the present invention in a predetermined area including the point where the browsing request is requested. To do. This hazard map is composed of, for example, the display information of the first layer and the display information of the second layer superimposed on the first layer. As the display information of the first layer, the map information of a predetermined area is read from the map information DB 54 and set, and as the display information of the second layer, at least detected by the slave units AA to CC. The display information is set so that the icon indicating the water level of the water level information is arranged at the coordinates of the point where the water level information is acquired. The display information of the second layer includes an icon of the shelter or underpass located at the coordinates of the shelter or underpass, and an icon indicating that the water has been flooded located at the coordinates of the flooded point. be able to.
In the following description, when the slave units AA to CC are collectively indicated, or when any of them is indicated, the slave unit 20 will be described. Similarly, when the master units A, B, and C are collectively indicated, or when any of the master units is indicated, the description is made as the master unit 30.

Specifically, the data processing device 50 reads a map of a predetermined area including a point requested to view the hazard map from the map information DB 54 and sets it as display information of the first layer. The map DB 54 has coordinate data as map information in addition to topography, roads, and rivers. Further, the data processing device 50 reads out the position information of the slave unit 20 related to the slave unit ID of the water level information stored in the sensor information DB 52, that is, the coordinate position of the slave unit 20 with reference to the sensor coordinate DB 51. The display position (coordinate position) on the second layer corresponding to the point where the slave unit 20 is installed on the map set in the first layer is determined. Then, the data processing device 50 sequentially reads out the water level information stored in the sensor information DB 52 at the same time, and displays an icon indicating the water level indicated by the sensor information in the water level information as the water level. It is arranged at the coordinates of the installation position of the slave unit 20 corresponding to the slave unit ID associated with the information, and is set as the display information of the second layer. In this case, the water level information is written in the sensor information DB 52 in real time, and the icon of the water level information at the same acquisition time is displayed at the coordinates of the point where the slave unit 20 that has detected the water level information is installed. Will be. In this case, the time of the water level information at the same time read from the sensor information DB 52 is the current time requested for browsing and some past times immediately past that time. Then, a hazard map for each time from the past time to the current time is created. In the hazard map of the current time, an icon indicating the water level information at that time will be displayed in real time on the map. If the time requested for browsing does not match the time when the water level information is acquired, the latest time before that is set as the current time.

It can be installed anywhere in Area B. In this case, an anchor nut is newly installed on the ground which is the ground of the flood generation area 107, and the slave unit BC is fixed to the anchor nut. The occurrence of the flooding area 107 can be known by receiving information from the local residents.
In the past, it was not possible to install a slave unit beyond the communication area of the master unit, but in the second embodiment of the hazard map system 1 provided with the sensing unit of the present invention, closed communication is possible between the slave units. Since it has a function, even if the flood information obtained by visual inspection and passage by local residents is outside the communication area of the master unit, if it is an area where the slave units can communicate with each other, it can be placed where necessary. It will be possible to monitor the location of flooding by installing slave units equipped with as many sensors as necessary.

In area C, a lamp line 100 is laid from blocks C-1 to C-3, and the lamp line 100 is stretched between utility poles 101, and blocks C-1, C-4, C-7 and blocks. A river 102 flows between C-2, C-5, and C-8. Two master units, a master unit C and a master unit D, are installed in the area C, and the master unit C is near the intersection between blocks C-2, C-3, C-5, and C-6. It is installed on the road, and the range of the master unit C communication area 114 is a substantially circular range shown in the figure. Further, the master unit D is installed on the road near the intersection between blocks C-4, C-5, C-7, and C-8, and the range of the master unit D communication area 115 is substantially circular as shown in the figure. It is a range, and the master unit C communication area 114 and the master unit D communication area 115 partially overlap. The slave units CA and CB are in the master unit C communication area 114, and the slave unit CA is installed in the block C-5 and the slave unit CB is installed in the block C-2. There is. Here, as shown in FIG. 8, it is assumed that flooding occurs between the blocks C-4 and the block C-7, and the flooding generation area 108 occurs. By installing the slave unit in the flood generation area 108, accurate flood information can be obtained. The flood generation area 107 is located outside the range of the master unit C communication area 114, but since it is within the master unit D communication area 115, a slave unit CC is newly installed at a position within the flood generation area 108. Install. As a result, the range covered by the closed communication network 14C can be expanded.
The occurrence of the flooded area 108 can be known by receiving information from the local residents. In the past, it was not possible to install a slave unit beyond the communication area of the master unit, but in the third embodiment of the hazard map system 1 including the sensing unit of the present invention, a closed communication network including two master units. Therefore, even if the submergence information obtained by visual inspection and passage by local residents is outside the communication area of one master unit, it is necessary where it is necessary if it is in the communication area of another master unit. It will be possible to monitor the location of flooding by installing a slave unit equipped with a sensor.

Next, in the fourth embodiment of the hazard map system 1 provided with the sensing unit of the present invention, an example of the installation position of the master unit A and the slave units AA and AB is shown in FIG.
The map of the area A consisting of 9 blocks of blocks A-1 to A-9 shown in FIG. 9 is a map corresponding to the range covered by the closed communication network 14A in the hazard map system 1 shown in FIG. In area A, a lamp line 100 is laid from blocks A-1 to A-3, and the lamp line 100 is stretched between utility poles 101, and blocks A-1, A-4, A-7 and blocks. A river 102 flows between A-2, A-5, and A-8. The master unit A is installed on the road near the intersection between blocks A-2, A-3, A-5, and A-6, and the range of the master unit A communication area 110 is a substantially circular range shown in the figure. Become. In the master unit A communication area 110, there are three flooding occurrence record areas 120, 121, 122 that have been flooded in the past, and the slave units AA are in the respective flooding occurrence record areas 120, 121, 122. , AB, AC are installed. Specifically, in the master unit A communication area 110, the slave unit AA is installed in the flooding occurrence record area 120 of the block A-5, and the child unit AA is installed in the flooding occurrence record area 121 of the block A-2. Machines AB are installed, and slave units AC are installed in the flooding record area 122 of block A-6.

Here, the precipitation amount at a predetermined time point, for example, 10:00 time in the area A is acquired from the rainfall information DB 53. At this point, it is assumed that precipitation of 20 mm for 1 hour has passed for 1 hour, and the flood data at this point is acquired by the information distribution server 12a from the sensor coordinate DB 51 and the sensor information DB 52. It is assumed that the information distribution server 12a has found that the flood has occurred in the flood occurrence record area 120 at 10:00. Therefore, in the data processing device 50, it is determined that the flooding has occurred in the flooding record areas 121 and 122 based on the information that the flooding has occurred in the flooding record area 120. The information distribution server 12a creates a hazard map at the above time point based on the fact that the flooding record areas 120, 121, and 122 are flooded.
Although not shown, a flooding record information DB that stores the location of the flooding record area, the flood level, and the like is provided in the database unit 12c.
Further, in the description of the first to fourth embodiments of the hazard map system 1 provided with the sensing unit of the present invention described above, the closed communication network 14 has been specifically described, but the first to fourth embodiments have been specified. Can be applied to any closed communication network 14.

Next, FIG. 15 shows a flowchart of the slave unit processing executed in the slave unit 20. When the slave unit 20 is installed at a predetermined position and the power supply device 26 is turned on, the microcontroller 21 starts the slave unit processing shown in FIG. The slave unit processing is actually executed by the CPU 41 in the microcontroller 21, but for convenience of explanation, it will be described as being executed by the microcontroller 21. When the slave unit processing is started, in step S10, the microcontroller 21 sets the slave unit ID, which is a unique individual identification number given to each slave unit 20, and the password for authentication of the slave unit 20. It is transmitted to the master unit 30. Next, in step S11, the microcontroller 21 determines whether or not the connection authentication of the slave unit 20 to the master unit 30 in the closed communication is completed. Here, if the connection authentication is not completed (NO), the processes of steps S10 and S11 are repeatedly executed until the connection authentication is completed, and if the microcontroller 21 determines that the connection authentication is completed (YES), the process proceeds to step S12. In step S11, connection authentication to the master unit 30 when the installation position of the slave unit 20 is moved, connection authentication of the slave unit 20 to the master unit 30 via another slave unit 20, and two master units 30 Connection authentication is performed in the closed communication network 14 provided with the above. Next, in step S12, the microcontroller 21 determines whether or not the position information of the point where the slave unit 20 is installed has been acquired. In step S12, the positioning device 23 determines whether or not the current position, that is, the position information which is the coordinates of the point where the slave unit 20 is installed, is acquired from the positioning unit such as GPS. Here, if the position information is not acquired (NO), the process waits until the position information is acquired, and if the microcontroller 21 determines that the position information has been acquired (YES), the process proceeds to step S13. In step S13, the microcontroller 21 adds the ID assigned to the slave unit 20 to the acquired position information, and transmits the ID to the master unit 30 to which the slave unit 20 belongs via the closed communication network.

Next, in step S14, the microcontroller 21 detects the water level detected by the sensor 22 and the acquisition time thereof. Next, in step S15, the microcontroller 21 determines whether or not the detected water level exceeds a predetermined predetermined water level. Here, if the microcontroller 21 determines that the specified water level has been exceeded (YES), the state proceeds to step S16, and the microcontroller 21 transmits the sensor information acquired from the sensor 22 and the water level information consisting of the acquisition time to the closed communication network 14. It is transmitted to the master unit 30 to which it belongs via. Next, the microcontroller 21 proceeds to step S17, waits for a short period of time, for example, 1 minute, returns to step S14 when the short-term waiting time ends, and repeats the processes of steps S14 to S17 described above. .. As a result, as long as the state in which the microcontroller 21 determines that the specified water level has been exceeded in step S15 continues, the microcontroller 21 has the sensor information acquired from the sensor 22 every short period (for example, 1 minute) and the sensor information thereof. The water level information consisting of the acquisition time will be transmitted to the master unit 30.

If the microcontroller 21 determines that the water level detected in step S15 does not exceed the specified water level (NO), it branches to step S18 and the microcontroller 21 branches from the previous transmission to the master unit 30. For example, it is determined whether or not a long period of 12 hours has passed. If the microcontroller 21 determines that a long period of time has passed (YES), the process proceeds to step S19 to transmit the sensor information acquired from the sensor 22 and the water level information consisting of the acquisition time to the master unit 30. Then, the process proceeds to step S20. If the microcontroller 21 determines in step S18 that a long period of time has not passed (NO), the process branches to step S20. In step S20, the microcontroller 21 waits for a medium period of, for example, 10 minutes, returns to step S14, and repeats the processes after step S14 described above. As a result, as long as the state in which the microcontroller 21 determines that the water level does not exceed the specified water level in step S15 continues, the microcontroller 21 acquires the sensor information from the sensor 22 every long period (for example, 12 hours). The water level information including the acquisition time and the acquisition time is transmitted to the master unit 30, and the processes after step S14 are repeated every medium period (for example, 10 minutes).
The slave unit processing is executed as long as the power supply device 26 of the slave unit 20 is turned on, and the slave unit processing ends when the power supply device 26 is turned off.

Next, FIG. 16 shows a flowchart of the master unit processing executed by the master unit 30. When the master unit 30 is installed at a predetermined location and the power supply device 34 is turned on, the microcontroller 31 starts the master unit processing shown in FIG. The master unit processing is actually executed by the CPU 41 in the microcontroller 31, but for convenience of explanation, it will be described as being executed by the microcontroller 31. When the master unit processing is started, in step S30, the microcontroller 31 receives the data transmitted from the slave unit 20 belonging to the master unit 30. When this data is an ID and a password for authentication, the microcontroller 31 performs connection authentication and establishes communication between the slave unit 20 and the master unit 30. The connection authentication is performed by checking the match with the authentication password corresponding to the ID of the slave unit 20 in which the microcontroller 31 is stored. If the data is the position information of the slave unit 20 to which the ID is added, or the water level information consisting of the sensor information acquired by the slave unit 20 and the acquisition time, the process proceeds to step S31, and the microcontroller 31 uses the wide area communication network 13. The data sent from the slave unit 20 is transmitted to the data processing server 12b of the information providing unit 12 via the above. The transmission from the master unit 30 to the data processing server 12b of the information providing unit 12 is performed every time the data from the slave unit 20 is received. The master unit processing ends when the power supply device 34 is turned off.

The information providing unit 12 provides the position information of the slave unit 20 to which the ID transmitted from the master unit 30 is added, or the water level information consisting of the sensor information acquired by the slave unit 20 and the acquisition time, in the wide area communication network communication I /. Received via F12d, the data processing server 12b stores it in the sensor coordinate DB 51 or the sensor information DB 52. FIG. 17 shows a flowchart of the DB writing process executed by the data processing server 12b.
The DB writing process shown in FIG. 17 is started when the power of the data processing server 12b is turned on. When activated, the CPU 71 receives data from the master unit 30 in step S40. If it cannot be received, wait until it can be received. The data to be received is the position information of the slave unit 20 to which the ID is added, or the water level information consisting of the sensor information acquired by the slave unit 20 and the acquisition time thereof. Next, in step S41, when the received data is the position information of the slave unit 20 to which the ID is added, the CPU 71 writes the position information in association with the ID in the sensor coordinate DB 51 via the I / O 74, and the slave unit. In the case of the sensor information acquired by 20, the acquisition time and the water level information are written in the sensor information DB 52 via the I / O 74 in relation to the ID of the handset 20 that has acquired the acquisition time and water level information. When the process of step S41 is completed, the process returns to step S40, and the processes of steps S40 and S41 are repeatedly executed. The DB write process ends when the power of the data processing server 12b is turned off.

Next, FIG. 18 shows a flowchart of the message delivery process (1) executed by the information delivery server 12a. The message delivery process (1) shown in FIG. 18 is activated when the power of the information delivery server 12a is turned on. The information distribution server 12a has the configuration shown in FIG. 14B as described above.
When the message delivery process is activated, in step S50, the CPU 61 determines whether or not a predetermined time (for example, 1 minute) has elapsed since the previous delivery. Here, if the CPU 61 determines that the predetermined time has not elapsed (NO), the process waits in step S50 until the predetermined time elapses. If the CPU 61 determines that the predetermined time has elapsed in step S50 (YES), the process proceeds to step S51 and the CPU 61 creates a warning message or a warning release message. In this case, the water level information at the latest time detected by the slave unit 20 is read from the sensor information DB 52, and when the CPU 61 determines that there is an area where the danger of flooding is imminent, a warning message is created and the danger of flooding is created. When the CPU 61 determines that there is an area left, a warning release message is created. Next, in step S52, the CPU 61 extracts a registrant whose warning area, which is an area where danger is imminent, is registered in the registrant information DB 55. Then, in step S53, the CPU 61 determines whether or not the created message has been delivered. Here, when the CPU 61 determines that the delivery has not been completed (NO), the message created by branching to step S54 and delivered to the registrant extracted in step S52 is delivered. If the CPU 61 determines that the distribution has been completed (YES) and the process of step S54 is completed, the process returns to step S50 and the processes of steps S50 to S54 are repeatedly executed. In this way, a warning / warning release message is created at a predetermined time, for example, every minute, and the message is delivered to the registrants in the area. Therefore, the registrants are in danger / danger without delay. I can understand that I have left.

Judge whether the water level of the sensor information of is changed. Here, if the CPU 61 determines that the water level has not changed (NO), it waits in step S60 until the water level changes. If the CPU 61 determines that the water level has changed in step S60 (YES), the process proceeds to step S61, and the CPU 61 creates a warning message or a warning release message. In this case, a warning message is created when the CPU 61 determines that the water level has changed to the extent that the danger of flooding is imminent, and the warning is canceled when the CPU 61 determines that the water level has changed to the extent that the danger of flooding has disappeared. The message is created. Next, in step S62, the CPU 61 designates a mobile phone base station in the warning area, which is considered to be an area where danger is imminent. Then, in step S63, the CPU 61 determines whether or not the created message has been delivered. Here, if the CPU 61 determines that the distribution has not been completed (NO), the message is branched to step S64 and the message created from the mobile phone base station specified in step S62 is distributed to the registrants registered in the registrant information DB 55. To do. If the CPU 61 determines that the distribution has been completed (YES) and the process of step S64 is completed, the process returns to step S60 and the processes of steps S60 to S64 are repeatedly executed. In this way, a warning message is created when the water level changes to the extent that the danger of flooding is imminent, and the warning message is delivered to the registrants in that area, so that the registrants are in danger without delay. I can understand that.

Next, in step S82, the CPU 71 acquires the water level information from the sensor information DB 52 at the same acquisition time of each slave unit 20 in the set area. In this case, the water level information at the same time read from the sensor information DB 52 is the water level information of the current time requested to be browsed and some past times immediately past that time, and the read water level. Information is organized by time. Then, in step S83, the CPU 71 acquires the coordinates of each slave unit 20 in the set area from the sensor coordinate DB 51, and at the coordinate position of each slave unit 20, the water level of each slave unit 20 collected for each acquired time. An icon representing is placed and set as display information of the second layer for each time. In this case, for example, when the current time is 10:03, the display information of the second layer for each time of 10:00, 10:01, 10:02, 10:03 is set. Next, in step S84, the CPU 71 acquires the coordinates of the evacuation shelter and the underpass in the set area from the evacuation information DB (not shown) provided in the database unit 12c, and arranges the evacuation shelter and the underpass icons at each coordinate position. Then, it is set as the display information of the second layer. Next, in step S85, the CPU 71 determines a submerged area according to the water level of each slave unit 20 collected for each acquired time, and arranges a submerged caution icon on the road or underpass in the area. And set it as the display information of the second layer for each time. In this case, the CPU 71 determines the flooded area according to the acquired water level of each slave unit 20, and if there is an evacuation center in the determined flooded area, the display mode of the evacuation center icon blinks or lights up or the color tone To change. Further, in step S86, the CPU 71 creates image data in which the display information of the first layer, the display information of the second layer, and the display information of the second layer for each time are superimposed for each time, and creates the image data separately for each time. Create a hazard map for each time. When the process of step S86 is completed, the hazard map creation process is completed, and the process returns to step S72 of the browsing request process.

The viewer requests the information providing unit 12 to view the hazard map from the browser on his / her mobile phone 10a or PC 10b, and the image of the hazard map distributed from the information distribution server 12a of the information providing unit 12. The data will be displayed in the browser. In this case, the hazard map delivered to the viewer is a plurality of hazard maps of the current time requested for viewing and some past times that are the latest in the past from that time. As a result, the viewer can observe the change in the water level with the passage of time by scrolling the screen. By editing and distributing multiple hazard maps of the current time and some past times that are more recent than that time into a video, the viewer can see the hazards from the past time to the current time. Changes in the map can be observed with a hazard map that has been made into a movie.
