[Embodiment 1: Disaster information collection process]
FIG. 4 is a diagram showing a flow of disaster information collection processing according to the first embodiment.

When a disaster occurs, the management device 10 executes a "disaster information collection process" for collecting disaster information. In the present embodiment, the method of collecting disaster information by the disaster information collection process is also referred to as "disaster information collection method", and the program for causing the computer to execute the disaster information collection process is also referred to as "disaster information collection program".

In step 401, the management device 10 collects the measurement data of the detection device 2.

In step 402, the management device 10 collects the gas supply stop status in the shutoff device 3.

In step 403, the management device 10 uses the plurality of breaking devices 3 existing in the area A as the first breaking device and the second breaking device based on the gas supply stop status in the breaking device 3 collected in step 402. Determine.

In step 404, the management device 10 discriminates the plurality of blocks B into the first block and the second block based on the discrimination results of the first blocking device and the second blocking device in step 403.

In step 405, the management device 10 executes a flight route determination process for determining the flight route R of the flying object 5 based on the determination result of the first blocking device and the second blocking device in step 403. The details of the flight route determination process will be described later with reference to FIGS. 5 and 6.

In step 406, the management device 10 flies the flying object 5 on the flight route R determined by step 405.

In step 407, the management device 10 analyzes the optical image and the infrared image acquired by the flying object 5 flying in step 406, and collects the damage situation of the area A.

In step 408, the management device 10 implements the necessary security measures based on the various information collected in steps 401-404 and 407. For example, the management device 10 remotely controls the shutoff device 3 whose gas supply has not been stopped based on the gas supply stop status in the shutoff device 3 and the damage status acquired by the flying object 5, and supplies the gas. Take security measures to stop. After step 408, the management device 10 ends this process.

FIG. 5 is a diagram showing a flow of flight route determination processing according to the first embodiment. FIG. 6 is a diagram for explaining a flight route R determined by the process shown in FIG.

The flight route determination process is a process for determining the flight route R of the aircraft 5 in the entire area A. However, in the explanation using FIG. 6, in order to facilitate the understanding of the flight route determination process, how the flight route R within one block B included in the area A is determined will be described as an example. ..

In FIG. 6, a plurality of governors G (1) to G (7) exist in one block B, and one blocking device 3 is installed in each of the plurality of governors G (1) to G (7). An example is shown. In FIG. 6, the governor G described as "open" indicates that the shutoff device 3 installed in the governor G does not stop the gas supply but corresponds to the first shutoff device. In FIG. 6, the governor G described as “closed” indicates that the shutoff device 3 installed in the governor G has stopped supplying gas and corresponds to the second shutoff device.

In step 501, the management device 10 determines whether or not the first blocking device exists as a result of discriminating between the first blocking device and the second blocking device in step 403 of FIG. The management device 10 proceeds to step 513 when the first shutoff device does not exist. On the other hand, the management device 10 shifts to step 502 when the first shutoff device is present.

In the example of FIG. 6, the blocking device 3 installed in the governors G (1) to G (3) exists as the first blocking device.

In step 502, the management device 10 determines the first blocking device closest to the remote base D equipped with the flying object 5 as the first waypoint in the flight route R of the flying object 5. In the present embodiment, the point where the aircraft 5 departing from the remote base D passes through the xth point is also referred to as a “xth way point”. x is an argument that takes a natural number value. The lower limit of x is 1, and the upper limit of x is the total number of blocking devices 3 existing in the area A. That is, the first transit point is the point where the aircraft 5 departing from the remote base D first passes through.

In the example of FIG. 6, the blocking device 3 installed in the governor G (1) corresponds to the first blocking device closest to the remote base D. Therefore, the management device 10 determines the blocking device 3 installed in the governor G (1) as the first waypoint.

In step 503, the management device 10 determines whether or not the first blocking device exists in the blocking device 3 adjacent to the mth waypoint. This mth waypoint is a waypoint determined immediately before executing step 503. m is an argument that takes the value of a natural number. The management device 10 proceeds to step 505 when the first blocking device does not exist in the blocking device 3 adjacent to the mth waypoint. On the other hand, the management device 10 shifts to step 504 when the first blocking device is present in the blocking device 3 adjacent to the mth waypoint.

In step 504, the management device 10 determines the first blocking device adjacent to the mth waypoint as the (m + 1) waypoint. The first (m + 1) waypoint is the point where the aircraft 5 passes after the mth waypoint. When there are a plurality of first cutoff devices adjacent to the m waypoint, the first cutoff device closest to the m waypoint is selected among the plurality of first cutoff devices adjacent to the m waypoint. (M + 1) Determine the waypoint. After step 504, the management device 10 shifts to step 506.

In the example of FIG. 6, the blocking device 3 installed in the governor G (1) is the first transit point, but the blocking device 3 installed in the governor G (2) is the first transit point adjacent to the first transit point. 1 Corresponds to a blocking device. Therefore, the management device 10 determines the blocking device 3 installed in the governor G (2) as the second transit point. Similarly, since the breaking device 3 installed in the governor G (3) corresponds to the first breaking device adjacent to the second transit point, the management device 10 uses the breaking device 3 installed in the governor G (3). , Determine the third waypoint.

In step 505, the management device 10 determines the second blocking device adjacent to the mth waypoint as the (m + 1) waypoint. When there are a plurality of second blocking devices adjacent to the m transit point, the route to the first blocking device closest to the m transit point among the plurality of second blocking devices adjacent to the m transit point. The second blocking device existing in the vicinity is determined as the first (m + 1) waypoint. After step 505, the management device 10 shifts to step 506.

In step 506, the management device 10 determines whether or not all the first blocking devices included in the result determined by the first blocking device have been determined as transit points. If the management device 10 has not determined all the first blocking devices as transit points, the management device 10 proceeds to step 503. On the other hand, when the management device 10 determines all the first blocking devices as transit points, the management device 10 proceeds to step 507. When the transition from step 506 to step 503, if neither the first blocking device nor the second blocking device exists in the blocking device 3 adjacent to the m transit point, the m transit point is used. The closest first blocking device may be determined as the first (m + 1) waypoint.

In the example of FIG. 6, when the blocking device 3 installed in the governor G (3) is determined as the third transit point, all the first blocking devices are determined as the transit points.

In step 507, the management device 10 determines whether or not there is a second blocking device to be added to the flight route R among the second blocking devices deviating from the route passing through the waypoint determined in steps 502 to 506. To do. The management device 10 is a second blocking device that exists in the second blocking device that deviates from the route that passes through the determined transit point, for example, in the vicinity of equipment important for security or on soft ground. If there is, these second blocking devices can be added to the flight route R. The management device 10 proceeds to step 512 when there is no second blocking device to be added to the flight route R among the second blocking devices deviating from the route passing through the determined waypoint. On the other hand, the management device 10 shifts to step 508 when there is a second blocking device to be added to the flight route R among the second blocking devices deviating from the route passing through the determined waypoint.

In step 508, the management device 10 selects the second blocking device to be added to the flight route R from the second blocking devices deviating from the route passing through the waypoints determined in steps 502 to 506.

In the example of FIG. 6, the second blocking device deviating from the route via the governors G (1) to G (3) is the blocking device 3 installed in the governors G (4) to G (7). Among the blocking devices 3 installed in the governors G (4) to G (7), the second blocking device to be added to the flight route R is the blocking device 3 installed in the governors G (5) and G (7). If this is the case, the management device 10 selects the blocking device 3 installed in the governors G (5) and G (7).

In step 509, among the second breaking devices selected in step 508, the management device 10 selects the second breaking device closest to the nth passing point, which is the last passing point of the first breaking device, (n + 1). ) Determine the waypoint. n is an argument that takes a natural number value. The (n + 1) th waypoint is a point where the aircraft 5 passes next to the nth waypoint.

In the example of FIG. 6, the last waypoint of the first cutoff device is the cutoff device 3 installed in the governor G (3) determined as the third waypoint. The breaking device 3 installed in the governor G (5) corresponds to the second breaking device closest to the last waypoint of the first breaking device among the selected second breaking devices. Therefore, the management device 10 determines the blocking device 3 installed in the governor G (5) as the fourth waypoint.

In step 510, the management device 10 determines, among the second blocking devices selected in step 508, the second blocking device closest to the first passing point as the (p + 1) passing point. This p-th waypoint is a waypoint determined immediately before executing step 510. p is an argument that takes a natural number value. The first (p + 1) waypoint is the point where the aircraft 5 passes after the pth waypoint. If there is no second blocking device to be determined at the (p + 1) waypoint among the second blocking devices selected in step 508, the management device 10 omits step 510 and proceeds to step 511. ..

In the example of FIG. 6, the breaking device 3 installed in the governor G (5) is the fourth waypoint, but the breaking device 3 installed in the governor G (7) is the selected second breaking device. Among them, it corresponds to the second blocking device closest to the fourth transit point. Therefore, the management device 10 determines the blocking device 3 installed in the governor G (7) as the fifth waypoint.

In step 511, the management device 10 determines whether or not all the second blocking devices selected in step 508 have been determined as transit points. If the management device 10 has not determined all the selected second blocking devices as transit points, the management device 10 proceeds to step 510. On the other hand, when the management device 10 determines all the selected second blocking devices as transit points, the management device 10 proceeds to step 512.

In the example of FIG. 6, when the blocking device 3 installed in the governor G (7) is determined as the fifth transit point, all the selected second blocking devices are determined as the transit points.

In step 512, the management device 10 determines the flight route R of the flying object 5 via the first to xth transit points in the order of determining the first to xth transit points determined in steps 502 to 511. .. After step 512, the management device 10 ends this process.

In the example of FIG. 6, the blocking devices 3 installed in the governors G (1), G (2), G (3), G (5) and G (7) are located at the first to fifth transit points. is there. The management device 10 takes a route that goes through the blocking devices 3 installed in the governors G (1), G (2), G (3), G (5), and G (7) in this order, and the flight route of the flying object 5. Determine to R.

In step 513, the management device 10 determines a predetermined route as the flight route R of the flying object 5. After step 513, the management device 10 ends this process.

[Embodiment 1: Action / Effect]
As described above, the management device 10 according to the first embodiment determines the flight route R of the flying object 5 by the procedure as shown in FIG. Therefore, in the management device 10, if one of the adjacent blocking devices 3 is the first blocking device and the other is the second blocking device, the installation point of the first blocking device whose gas supply has not been stopped has been stopped. It is possible to fly to the flying object 5 in preference to the installation point of the second blocking device. As a result, the disaster information collection system 1 according to the first embodiment can preferentially collect disaster information at the installation point of the first shutoff device where a secondary disaster is likely to occur. In addition, in the disaster information collection system 1 according to the first embodiment, the installation point of the second shutoff device other than the second cutoff device existing around the equipment important for safety is regarded as a relatively safe point. The collection of disaster information at the installation point of this second blocking device can be separated. Therefore, the disaster information collection system 1 according to the first embodiment can collect disaster information quickly and efficiently, and can effectively suppress secondary disasters.

In general, a good ground such as a solid ground is relatively hard to shake even if an earthquake occurs, and even if a large earthquake with a seismic intensity of 6 lower or higher occurs, the gas supply may not be stopped depending on the blocking device 3. .. In this case, if a fire breaks out in area A with the gas leaking, the leaked gas may ignite and a secondary disaster may occur. The disaster information collection system 1 according to the first embodiment can preferentially collect disaster information from the installation point of the first shutoff device whose gas supply has not been stopped. Therefore, in the event of a fire or the like, this disaster information collection system 1 can be used. The first shutoff device can be remotely controlled to immediately stop the gas supply. Therefore, the disaster information collection system 1 according to the first embodiment can effectively suppress the occurrence of a secondary disaster.

[Other Embodiments]
The disaster information collection system 1 according to the second and third embodiments will be described. In the description of the disaster information collection system 1 according to the second and third embodiments, the description relating to the same configuration and operation as the disaster information collection system 1 according to the first embodiment will be omitted because the description will be duplicated.

As shown in steps 405 and 5 of FIG. 4, the management device 10 according to the first embodiment has a flight route R of the flying object 5 based on the determination result of the first blocking device and the second blocking device in step 403. To determine.

On the other hand, the management device 10 according to the second embodiment determines the flight route R of the flying object 5 based on the determination results of the first block and the second block in step 404. That is, the management device 10 according to the second embodiment determines the flight route R of the flying object 5 in block B units.

FIG. 7 is a diagram showing a flow of flight route determination processing according to the second embodiment. FIG. 8 is a diagram for explaining a flight route R determined by the process shown in FIG. 7.

FIG. 8 shows an example in which a plurality of blocks B (1) to B (14) exist in the area A. In FIG. 8, it is shown that the hatched block B corresponds to the first block including the first blocking device in the plurality of blocking devices 3 belonging to the block B. In FIG. 8, it is shown that the unhatched block B corresponds to a second block in which the first blocking device is not included in the plurality of blocking devices 3 belonging to the block B.

In step 701, the management device 10 determines whether or not the first block exists in the area A as a result of discriminating between the first block and the second block in step 404 of FIG. If the first block does not exist, the management device 10 proceeds to step 713. On the other hand, the management device 10 shifts to step 702 when the first block exists.

In the example of FIG. 8, the blocks B (2), B (6), B (11), B (12) and B (14) exist as the first block.

In step 702, the management device 10 determines the first block closest to the remote base D equipped with the aircraft 5 as the first transit area on the flight route R of the aircraft 5. In the present embodiment, the area through which the aircraft 5 departing from the remote base D passes through the xth is also referred to as the “xth way area”. x is an argument that takes a natural number value. The lower limit of x is 1, and the upper limit of x is the total number of blocks B existing in the area A. That is, the first transit area is the area where the aircraft 5 departing from the remote base D first passes through.

In the example of FIG. 8, block B (2) corresponds to the first block closest to the remote base D. Therefore, the management device 10 determines the block B (2) as the first transit area.

In step 703, the management device 10 determines whether or not the first block exists in the block B adjacent to the mth transit area. This mth transit area is a transit area determined immediately before executing step 703. m is an argument that takes the value of a natural number. The management device 10 proceeds to step 705 when the first block does not exist in the block B adjacent to the mth transit area. On the other hand, the management device 10 shifts to step 704 when the first block exists in the block B adjacent to the mth transit area.

In step 704, the management device 10 determines the first block adjacent to the mth transit area as the (m + 1) transit area. The first (m + 1) transit area is the area through which the aircraft 5 passes next to the mth transit area. When there are a plurality of first blocks adjacent to the mth transit area, the first block closest to the m transit area among the plurality of first blocks adjacent to the mth transit area is the first (m + 1). Determine the transit area. After step 704, the management device 10 shifts to step 706.

In the example of FIG. 8, block B (2) is the first transit area, but block B (6) corresponds to the first block adjacent to the first transit area. Therefore, the management device 10 determines the block B (6) as the second transit area. Similarly, since the block B (11) corresponds to the first block adjacent to the second transit area, the management device 10 determines the block B (11) as the third transit area. Similarly, since the block B (14) corresponds to the first block adjacent to the third transit area, the management device 10 determines the block B (14) as the fourth transit area.

In step 705, the management device 10 determines the second block adjacent to the mth transit area as the (m + 1) transit area. When there are a plurality of second blocks adjacent to the m-via area, they exist near the route to the first block closest to the m-via area among the plurality of second blocks adjacent to the m-via area. The second block to be used is determined as the (m + 1) transit area. After step 705, the management device 10 shifts to step 706.

In the example of FIG. 8, block B (14) is the fourth transit area, but block B (13) is the most in the fourth transit area among the plurality of second blocks adjacent to the fourth transit area. It corresponds to the second block existing near the route to the nearest first block (that is, block B (12)). Therefore, the management device 10 determines the block B (13) as the fifth transit area.

In step 706, the management device 10 determines whether or not all the first blocks included in the result determined in the first block have been determined as the transit area. If the management device 10 has not determined all the first blocks as transit areas, the management device 10 proceeds to step 703. On the other hand, when the management device 10 determines all the first blocks as transit areas, the management device 10 proceeds to step 707. When the transition from step 706 to step 703 occurs, if neither the first block nor the second block exists in the blocks adjacent to the mth transit area, the first block closest to the m transit area. The block may be determined as the first (m + 1) transit area.

In the example of FIG. 8, since the block B (12) corresponds to the first block adjacent to the fifth transit area, the management device 10 determines the block B (12) as the sixth transit area. In the example of FIG. 8, when the block B (12) is determined as the sixth transit area, all the first blocks are determined as the transit area.

In step 707, the management device 10 determines whether or not there is a second block to be added to the flight route R among the second blocks deviating from the route passing through the transit area determined in steps 702 to 706. When the management device 10 has a second block deviating from the route via the determined transit area, for example, there is a second block in which equipment important for security exists or exists on soft ground. These second blocks can be added to the flight route R. The management device 10 proceeds to step 712 when there is no second block to be added to the flight route R in the second block deviating from the route passing through the determined transit area. On the other hand, the management device 10 shifts to step 708 when there is a second block to be added to the flight route R in the second block deviating from the route passing through the determined transit area.

In step 708, the management device 10 selects a second block to be added to the flight route R from the second blocks deviating from the route passing through the transit area determined in steps 702 to 706.

In the example of FIG. 8, the second block deviating from the route via blocks B (2), B (6), B (11), B (14), B (13) and B (12) is block B. (1), B (3) to B (5) and B (7) to B (10). Among the blocks B (1), B (3) to B (5) and B (7) to B (10), the second block to be added to the flight route R is the blocks B (1) and B (4). If, the management device 10 selects blocks B (1) and B (4).

In step 709, the management device 10 sets the second block closest to the nth transit area, which is the last transit area of the first block, among the second blocks selected in step 708, as the (n + 1) transit area. To decide. n is an argument that takes a natural number value. The (n + 1) th transit area is an area through which the aircraft 5 passes next to the nth transit area.

In the example of FIG. 8, the last transit area of the first block is block B (12) determined to be the sixth transit area. Block B (4) corresponds to the second block closest to the last stopover area of the first block among the selected second blocks. Therefore, the management device 10 determines the block B (4) as the seventh transit area.

In step 710, the management device 10 determines the second block closest to the first via area among the second blocks selected in step 708 as the (p + 1) via area. This p-th transit area is a transit area determined immediately before executing step 710. p is an argument that takes a natural number value. The first (p + 1) transit area is the area through which the aircraft 5 passes next to the p-th transit area. If there is no second block to be determined in the (p + 1) transit area among the second blocks selected in step 708, the management device 10 omits step 710 and proceeds to step 711.

In the example of FIG. 8, block B (4) is the seventh transit area, but block B (1) corresponds to the second block closest to the seventh transit area among the selected second blocks. To do. Therefore, the management device 10 determines the block B (1) as the eighth transit area.

In step 711, the management device 10 determines whether or not all the second blocks selected in step 708 have been determined as transit areas. If the management device 10 has not determined all the selected second blocks as transit areas, the management device 10 proceeds to step 710. On the other hand, when the management device 10 determines all the selected second blocks as transit areas, the management device 10 proceeds to step 712.

In the example of FIG. 8, when the block B (1) is determined as the eighth transit area, all the selected second blocks are determined as the transit areas.

In step 712, the management device 10 determines the flight route R of the flying object 5 as the route passing through the first to xth transit areas in the order of determining the first to xth transit areas determined in steps 702 to 711. .. After step 712, the management device 10 ends this process.

In the example of FIG. 8, the blocks B (2), B (6), B (11), B (14), B (13), B (12), B (4) and B (1) are the first. ~ It is the 8th transit area. The management device 10 is a route that goes through blocks B (2), B (6), B (11), B (14), B (13), B (12), B (4), and B (1) in this order. Is determined as the flight route R of the aircraft body 5.

In step 713, the management device 10 determines the predetermined route as the flight route R of the flight body 5. After step 713, the management device 10 ends this process.

As described above, the management device 10 according to the second embodiment determines the flight route R of the flying object 5 by the procedure as shown in FIG. 7. Therefore, when one of the adjacent blocks B is the first block and the other is the second block, the management device 10 has stopped the first block to which the first shutoff device whose gas supply has not been stopped belongs. The flying object 5 may be made to fly in preference to the second block to which only a certain second blocking device belongs. As a result, the disaster information collection system 1 according to the second embodiment can preferentially collect disaster information in the first block to which the first blocking device, which is likely to cause a secondary disaster, belongs. In addition, in the disaster information collection system 1 according to the second embodiment, the second block other than the second block existing on the soft ground is regarded as a relatively safe area, and the disaster information is collected in this second block. Can be separated. Therefore, the disaster information collection system 1 according to the second embodiment can collect disaster information quickly and efficiently, and can effectively suppress secondary disasters.

FIG. 9 is a diagram for explaining a flight route R determined by the flight route determination process according to the third embodiment.

In the disaster information collection system 1 according to the first embodiment, the management device 10 does not particularly determine the detailed flight route Rf when flying from the s waypoint to the (s + 1) waypoint, and the flying object 5 autonomously. You can leave it to the flight. For example, in the disaster information collection system 1 according to the first embodiment, the detailed flight route Rf when flying from the s waypoint to the (s + 1) waypoint is as shown by the dashed arrow in FIG. The route may be such that the shortest distance is taken from the s waypoint to the (s + 1) waypoint.

On the other hand, in the disaster information collection system 1 according to the third embodiment, the management device 10 can also determine the detailed flight route Rf when flying from the s waypoint to the (s + 1) waypoint.

When there is a customer between the s waypoint and the (s + 1) waypoint, there is a gas meter installed for each customer between the s way point and the (s + 1) way point. .. The gas meter includes a sensor 7 such as a pressure sensor, a flow meter, and a seismic sensor, and can transmit the detection result of the sensor 7 and the identification information of the gas meter to the management device 10. The management device 10 can specify the installation position of the gas meter, that is, the installation position of the sensor 7 based on the identification information transmitted by the gas meter. The management device 10 can determine whether or not a disaster has occurred locally in the vicinity of the installation position of the sensor 7 from the detection result of the sensor 7 transmitted by the gas meter.

Therefore, the management device 10 according to the third embodiment has a detailed flight route when flying from the s waypoint to the (s + 1) waypoint based on the detection result of the sensor 7 provided in the gas meter and the installation position. Determine Rf. For example, as shown in FIG. 9, the sensor 7 that has detected the occurrence of a disaster and the sensor 7 that has not detected the occurrence of a disaster are unevenly distributed between the s waypoint and the (s + 1) waypoint. It is conceivable that it will be distributed. The black circle in FIG. 9 indicates the installation position of the sensor 7 that has detected the occurrence of a disaster, and the white circle in FIG. 9 indicates the installation position of the sensor 7 that has not detected the occurrence of a disaster. In this case, the management device 10 according to the third embodiment sets the flight route Rf via a place where many sensors 7 that have detected the occurrence of a disaster are present, as shown by the solid arrow in FIG. Decide on a route that will fly 5. As a result, the disaster information collection system 1 according to the third embodiment can collect detailed disaster information at points where secondary disasters are likely to occur, so that secondary disasters can be suppressed more effectively. ..
