(Fire extinguishing treatment)
Next, the process which the control part 93 of the fire extinguishing system 1 performs is demonstrated. FIG. 9 is a flowchart of the fire extinguishing process by the fire extinguishing system 1. It should be noted that the control unit 93 of the disaster prevention receiver 9 performs control that is not specified.

  First, the control unit 93 monitors whether or not the fire detector 2 has detected the occurrence of a fire based on whether or not the notification signal output from the fire detector 2 has been received by the communication unit 91 (step). SA-1). When the fire detector 2 detects the occurrence of a fire (step SA-1, Yes), the fire situation determination unit 94 executes a fire situation judgment process and identifies the fire occurrence position and the fire scale (step SA-2). . Details of this fire situation specifying process will be described later.

  After the fire occurrence position and the fire scale are specified, the selection unit 95 executes a selection process, and selects the number of the fire extinguisher transport devices 8 according to the fire situation and the fire extinguisher transport device 8 to be activated (step SA). -3). Details of this selection process will be described later.

  After the fire extinguisher transport device 8 is selected, the guide unit 96 performs a guidance process and guides the fire extinguisher transport device 8 to reach the fire occurrence position (step SA-4). Details of this guidance processing will be described later.

  After the fire extinguisher transport device 8 is guided, the fire situation determination unit 94 executes a fire extinguishing situation determination process and monitors until the fire extinguishing activity of the fire extinguisher transport apparatus 8 is completed or a stop instruction is given. If it has not been completed or if there is no fire extinguishing stop instruction, the process returns to the fire condition determination process in step SA-2. If the fire extinguishing activity is completed or if there is a fire extinguishing stop instruction, the fire extinguishing process is terminated ( Step SA-5). Details of this fire extinguishing status determination process will be described later.

(Fire extinguishing process-Fire status identification process)
Next, the fire situation specifying process in step SA-2 in FIG. 9 will be described. FIG. 10 is a flowchart of the fire situation specifying process. The fire situation determination unit 94 targets an area where the fire detector 2 has detected a fire in Step SA-2 described above, and receives an image signal captured by the camera 3 installed around the area via the communication unit 91. Receive (step SB-1).

  Next, the fire occurrence position specifying unit 94a performs image processing for specifying the fire occurrence position based on the image received from the communication unit 91 (step SB-2). For example, the fire occurrence position specifying unit 94a performs shape recognition and type recognition based on the luminance of each pixel in the image, and specifies the fire occurrence position by specifying the position of flame, smoke, water vapor, and the like. Next, the fire occurrence position specifying unit 94a determines whether or not the fire occurrence position has been specified (step SB-3). When it is determined that the fire occurrence position cannot be specified (No at Step SB-3), the fire occurrence position specifying unit 94a treats the fire detection by the fire detector 2 as being due to a false alarm, and the fire situation specifying process and the fire extinguishing process. Exit.

  On the other hand, when it is determined that the fire occurrence position can be specified (step SB-3, Yes), the fire occurrence position specifying unit 94a transmits measurement signals of wind direction and wind speed from all anemometers 4 installed in the tunnel. (Step SB-4). The fire scale specifying unit 94b then performs image processing for estimating the scale of the fire within a predetermined fire extinguishing time based on the image used in the image processing of the fire occurrence position specifying unit 94a and the wind direction / wind speed of the anemometer 4. (Step SB-5). For example, the fire scale specifying unit 94b specifies the area and height of fire smoke and the like from the image of the camera 3, and specifies the fire scale based on the direction of the estimated fire spread direction and the estimated fire spread range from the wind direction and speed. This completes the fire status identification process. The reason for estimating the fire size within the required fire extinguishing time in this way is that it is preferable to determine the position of the fire extinguishing appliance transporting device 8 in anticipation of the extent of fire spreading during the fire fighting activity. However, when the influence of fire spread can be ignored, such as when the wind speed is below a predetermined value, only the current fire magnitude may be specified from the image of the camera 3.

(Fire extinguishing process-selection process)
Next, the selection process in step SA-3 in FIG. 9 will be described. FIG. 11 is a flowchart of the selection process. The selection part 95 specifies the number of the fire extinguishing apparatus conveyance apparatuses 8 required for fire extinguishing (step SC-1). For example, the selection unit 95 identifies the number of fire extinguishing appliance transport apparatuses 8 that match the fire scale by referring to the control table of FIG. 7 based on the fire scale identified in Step SB-5 of FIG. 10. . In the example of FIG. 7, in the case of a fire that extends to a range of 3 m from the fire occurrence position, the number of fire extinguisher transport apparatuses 8 is equal to 2 (hereinafter, the fire extinguisher transport apparatus 8 specified in step SC-1 is determined). The number is referred to as “required number”).

  Next, the selection unit 95 uses the fire occurrence position specified in step SB-2 of FIG. 10 as a base point, and transports the fire extinguishers arranged within the range of the fire scale specified in step SB-5 of FIG. The device 8 is specified (step SC-2). Here, as shown in FIG. 12 (a), the fire extinguisher transport device 8 existing in the range of the fire scale centering on the fire occurrence position may be specified, but the fire extinguishing located on the windward side from the fire occurrence position may be specified. Since it is considered that the use of the appliance transporting device 8 has better fire extinguishing efficiency and can protect the human body from the heat of the fire, as shown in FIG. When the scale range is set, the fire extinguisher transport device 8 arranged in the fire scale range is selected (in FIGS. 12 (a) and 12 (b), the fire extinguisher transport device illustrated with diagonal lines). 8 shows the selected state). However, when the influence of the wind direction can be ignored, such as when the wind speed is equal to or lower than a predetermined value, the identification may be performed as shown in FIG. In addition, for this specification, only the fire extinguisher transport device 8 that is on standby (not yet used for fire extinguishing and can be dispatched) is targeted. For example, in the control table of FIG. 6, use history information of each fire extinguisher transport device 8 is stored, and by referring to this use history information, it is determined whether the fire extinguisher transport device 8 is on standby, Only the fire extinguisher transport device 8 that is in standby is specified (hereinafter, the number of the fire extinguishing device transport devices 8 specified in Step SC-2 is referred to as “selected number”).

  Next, the selection part 95 determines whether the required number of steps SC-1 and the number of selections of step SC-2 are the same (step SC-3). Here, when the selection part 95 determines with the number of both the fire extinguishing appliance conveyance apparatuses 8 being the same (step SC-3, Yes), the fire extinguishing appliance conveyance apparatus 8 selected by step SC-2 is finally decided. The selection process is terminated as the fire extinguisher transport device 8 used for fire extinguishing.

  On the other hand, when the required number and the selected number are not the same (step SC-3, No). The selection part 95 determines whether a required number is less than a selection number (step SC-4). And when a required number is less than a selection number (step SC-4, Yes), the selection part 95 fires until the required number and a selection number become the same among the fire extinguisher conveyance apparatus 8 selected by step SC-2. A fire extinguisher transport apparatus that uses the fire extinguisher transport apparatus 8 that is left without being excluded (step SC-5) in order from those arranged far from the generation position (or frequently used) (step SC-5). 8, the selection process is terminated. When the required number does not fall below the selected number (Step SC-4, No), the selection unit 95 fires the fire extinguishing appliance transporting device 8 selected at Step SC-2 until the required number and the selected number are the same. A fire extinguisher transport apparatus 8 that is used for extinguishing the fire extinguisher transport apparatus 8 including the added portion is added in order from the one arranged in the vicinity from the generation position (or the one that is less frequently used) (step SC-6). Then, the selection process is terminated.

(Fire extinguishing process-induction process)
Next, the guidance process of the fire extinguisher conveyance device 8 in step SA-4 of FIG. 9 will be described. FIG. 13 is a flowchart of the guidance process. The guide unit 96 identifies a travel route to the fire extinguishing position of each fire extinguishing appliance transport apparatus 8 finally selected in the selection process (step SD-1). For example, the guide unit 96 acquires the arrangement position of each fire extinguisher transport apparatus 8 finally selected in the selection process from the control table of FIG. 6, and uses the arrangement position as a base point in step SB-2 of FIG. Identify the travel route to the identified fire location.

  Next, the guide unit 96 identifies the RFID tag 5 arranged on the traveling route described above (step SD-2). For example, the guiding unit 96 refers to the control table in FIG. 8, identifies the RFID tag 5 arranged on the travel route identified in step SD- 1, and displays guidance information of the identified RFID tag 5 in the control table. Get from.

  And the guidance part 96 produces | generates the starting signal containing the induction | guidance | derivation information of the RFID tag 5 acquired by step SD-2, and the starting command for starting control of the fire extinguishing appliance conveyance apparatus 8, This selection signal is selected. It outputs to each fire extinguisher conveyance apparatus 8 finally selected by the process by the communication part 91 (step SD-3), and complete | finishes a guidance process.

(Fire extinguishing process-fire extinguishing status determination process)
Next, the fire extinguishing status determination process in step SA-5 in FIG. 9 will be described. FIG. 14 is a flowchart of the fire extinguishing status determination process. The activation signal output in the guidance process is input to the communication unit 83 of the fire extinguisher transport device 8 via the communication unit 63 of the storage box 6, and the control unit 93 of the fire extinguisher transport device 8 performs the fire extinguishing device transport process. By executing the above, the fire extinguisher transport device 8 is guided to the fire occurrence position. However, details of the fire extinguishing appliance guidance process will be described later.

  The fire situation determination unit 94 specifies the fire scale again by performing the same processing as Steps SB-1, SB-4, and SB-5 in FIG. SE-1, SE-2, SE-3). Then, the fire scale specifying unit 94b determines whether or not the specified fire scale has been reduced as compared with the fire scale specified in Step SB-5 of FIG. 10 (Step SE-4). Here, when it is determined that the fire scale is not reduced (step SE-4, No), there is a possibility that the fire scale may be expanded, and it may be necessary to increase the fire extinguishing equipment transport device 8, The fire scale specifying unit 94b proceeds to Step SA-2 in FIG. 9 and repeats Steps SA-2 to SA-5 to newly specify the fire extinguishing appliance transport apparatus 8 necessary for the expanded fire scale, The specified fire extinguishing appliance transporting device 8 is guided to the fire occurrence position.

  On the other hand, when it is determined that the fire scale is reduced (step SE-4, Yes), the fire situation determination unit 94 has completed extinguishing the fire at the fire occurrence position based on the fire scale specified in step SE-4. It is determined whether or not. At the same time, the fire condition determination unit 94 determines whether or not a fire extinguishing stop instruction has been received (step SE-5). For example, a stop button (not shown) attached to the fire extinguisher transport device 8, the storage box 6, or the like is operated, and a signal indicating the operation state is received by the communication unit 91 via the communication unit 83 or the communication unit 63. In the event of a fire, it is determined that an instruction to stop the fire is received. When there is no fire extinguishing completion or fire extinguishing stop instruction (step SE-5, No), the fire situation determination unit 94 returns to step SE-1 and repeats steps SE-1 to SE-5. On the other hand, when there is a fire extinguishing completion or fire extinguishing stop instruction (step SE-5, Yes), the fire situation determination unit 94 ends the fire fighting situation determination process, and thus the process of FIG. 9 ends.

(Fire extinguishing process-Fire extinguishing equipment transport process)
Next, the fire extinguisher conveyance process which the control part 88 of the fire extinguisher conveyance apparatus 8 performs is demonstrated. FIG. 15 is a flowchart of the fire-extinguishing appliance transport process.

To do. In addition, this activation signal is input from the communication unit 63 to the communication unit 83 of the fire extinguishing appliance transporting device 8 (step SF-1, Yes), and the guidance control unit 88a acquires the guidance information included in this activation signal (step). SF-2).

  And the guidance control part 88a controls the moving part 80, moves the fire extinguisher transport apparatus 8 from the storage box 6 to the outside, and makes the fire extinguisher transport apparatus 8 pass through the RFID tag 5 specified by the guide information. Move (step SF-3). Here, the guidance information of the RFID tag 5 is read by the RFID tag reader 87a, and it is determined whether or not it matches the guidance information included in the activation signal. Changes the current course by a predetermined angle and performs reading by the RFID tag reader 87a again. As a result of such control, the fire extinguisher transport device 8 moves along the traveling route determined in step SD-1 in FIG.

  The guidance control unit 88a determines whether or not a movement failure has occurred that makes it impossible to move to the fire occurrence position while the fire extinguisher transport device 8 is being moved (step SF-4). Specifically, when the presence of an obstacle or a person in the moving direction of the fire extinguisher transport device 8 is specified based on the image data captured by the camera 81, the guidance control unit 88a is assumed to have caused the movement obstacle. Determine (step SF-4, Yes). In this case, the guidance control unit 88a stops the movement of the fire extinguisher transport device 8, and transmits a fault signal to the disaster prevention receiver 9 via the communication unit 83 (step SF-5), and ends the fire extinguisher transport processing. To do. The disaster prevention receiver 9 that has received this failure signal replaces the fire extinguisher transport device 8 that is installed at the optimum position for transporting the fire extinguisher 7 based on the fire occurrence position among the fire extinguishing device transport devices 8 that are on standby. Select and send activation signal.

  On the other hand, when the movement obstacle has not occurred (step SF-4, No), the guidance control unit 88a determines whether or not the fire source has been specified based on the imaging data input from the camera 81 (step SF). -6). Until the fire source is specified (step SF-6, No), the guidance control unit 88a controls the moving unit 80 to continue the movement of the fire extinguishing appliance transporting device 8. The fire source may be specified at a position where the radiation sensor 86 can obtain radiant heat. Or you may identify a fire source with sensors, such as a flame detector separately provided in the fire extinguishing apparatus conveyance instrument 8. FIG.

  If it determines with having specified the fire source (step SF-6, Yes), the safety determination part 88b will make the radiation sensor 86 measure a radiant heat flux (step SF-7), and will perform safety determination according to a measurement result. (Step SF-8).

  Further, the fire source distance specifying unit 88d specifies the distance to the fire source based on the photographing data input from the camera 81 (step SF-9). The safety range maintaining unit 88c refers to the control table recorded in the recording unit 92 based on the determination result by the safety determination unit 88b and the fire source distance specified by the fire source distance specifying unit 88d, A control operation corresponding to the contents of the table is performed (step SF-10).
