[0032] After the vehicle-mounted control system 10 receives the fire instruction and the fire location information, according to the information collected by the movement guidance system and the detection system, it sends a movement control instruction to the vehicle-mounted drive system, so that the vehicle-mounted drive system controls the steering mechanism 4 and the driving and traveling mechanism 6, moves the mobile turbofan gun fire extinguishing device to the fire location, and controls each hydraulic outrigger 3 to extend and contact the ground. After playing a supporting role, it sends a lifting instruction to the vehicle-mounted drive system, controls the scissor boom 7 to open, raises the turbofan gun 1 to a predetermined fire extinguishing height, sends an alignment instruction to the vehicle-mounted drive system, controls the turbofan gun 1 to perform rotation and pitching actions, adjusts the position and pose of the turbofan gun 1 to align with the fire extinguishing point, and sends a fire extinguishing instruction to the vehicle-mounted drive system, so that the fire extinguishing agent is ejected from the turbofan gun 1 through the fire liquid pipeline system 5 for fire extinguishing.

[0033] Among them, the vehicle-mounted control system 10 is connected to the substation fire warning system through an optical fiber. When a fire occurs, the substation fire warning system will send a fire instruction and fire location information to the vehicle-mounted control system 10 of the mobile turbofan gun fire extinguishing device. The fire extinguishing agent can be foam, fine water mist, etc. When sending a fire extinguishing instruction to the vehicle-mounted drive system 10, the air flow generated by the fan at the rear end of the turbofan gun 1 passes through the air flow channel and ejects the fire extinguishing agent through the front nozzle, and the fire extinguishing agent is carried to a distant place for fire extinguishing.

According to the information collected by the moving guidance system, the current position of the mobile vortex fan gun fire extinguishing device can be determined, and then a moving control instruction is sent to the vehicle-mounted drive system 9, so that the vehicle-mounted drive system 9 controls the steering mechanism 4 and the driving walking mechanism 6. Starting from the current position of the mobile vortex fan gun fire extinguishing device and taking the landmark card corresponding to the fire position as the end point, it moves along the path indicated by the magnetic nails to the landmark card corresponding to the fire position. Landmark cards for identifying positions are arranged on both sides of the path indicated by the magnetic nails. The two vision sensors 11 on both sides of the head of the mobile vortex fan gun fire extinguishing device determine their own traveling positions by identifying the landmark cards. The fire position information of the substation fire warning system also uses the landmark card as a reference system. According to the fire position information and the two vision sensors 11 identifying the landmark cards to determine their own traveling positions, the navigation system controls the vortex fan gun fire truck to run to the fire position (the position of the landmark card corresponding to the fire point).

By manually operating the buttons of the manual control device, movement control instructions, lifting instructions, alignment instructions, fire extinguishing instructions, etc. are sent to the vehicle-mounted drive system 9 to achieve manual control of the turbofan cannon 1 to spray water mist for fire extinguishing.

[0043] In one embodiment, the mobile turbofan cannon fire extinguishing device further includes a wireless remote control device, which is arranged on the first side or the second side of the chassis assembly 8.
