Description

Technical Field

[0001] The invention belongs to the field of fire fighting equipment, and in particular relates to an automatic position-limiting fire fighting cannon. Background Art

[0002] The principle of the automatic fire monitor is to use a special red and ultraviolet detection system to monitor the burning point, and together with the central computer control system and the motor integration system, it automatically monitors all fire conditions in its protection area around the clock and in all directions. When a fire occurs, the device starts immediately, sends a signal to the fire control center, and alarms in real time. At the same time, it conducts a full-scale patrol scan. After accurately locating the fire extinguishing position, it drives the fire extinguishing device to extinguish the fire and extinguish the signs of the fire in its infancy. However, most of the current automatic fire monitors can only rotate within a fixed angle when working. When they are rotated to the maximum angle and are limited, they often do not send signals in time, which is not conducive to the monitoring work. Summary of the invention
