2. An automatic control method for an automatic fire monitor, characterized in that: after the computer 6 receives an alarm signal from a fire detector associated with the fire monitor and automatically confirms the fire signal by a preset program, The communication module 9 and the micro-processing module 8 of the decoder 5 send the information to the power drive module 7, and the power drive module 7 controls the horizontal motor and the pitch motor of the cannon body 1 to rotate, and the nozzle of the cannon body drives the flame image positioner 4 Carry out flame search and positioning in the horizontal direction and the pitch direction, the horizontal angle potentiometer and the pitch angle potentiometer of the cannon body transmit the position angle signal of the cannon body 1 to the data acquisition module 10 of the decoder in time, through the communication module of the decoder 5 9, the information is sent to the computer, and the video signal of the flame image locator 4 is also passed to the computer; after program analysis, the computer passes the action instruction to the power drive module 7 through the communication module 9, and the power drive module 7 controls the gun body 1 The horizontal motor and the pitching motor rotate to align the nozzle of the water monitor at the front of the flame surface; The information is fed back to the computer in time; once it is confirmed that the fire pump and the electric valve need to be started, the computer 6 sends a control command to the pump valve control panel 27, and the pump valve control panel 27 immediately starts the fire pump and the electric valve, and sprays water on the fire until the flame extinguish until the alarm signal of this road is eliminated; at the same time, the computer 6 continues to receive the feedback information from other fire detection alarms associated with the automatic fire monitor. If there is another fire alarm signal, the gun body 1 is extinguished After the flame in the current area, under the control of the decoder power drive module 7, the new ignition point is automatically searched and positioned and put out the fire until it is extinguished; After the elimination, the computer 6 sends control instructions to the pump valve control panel 27, and the pump valve control panel 27 closes the fire pump and electric valve in time, and the system automatically returns to the initial setting state, waiting for the next alarm signal.
