Design of a New Type of Control System for Free-swing Fire Monitor

In order to resolve the problem that existing normal water free-swing fire monitors are poor in universality, the paper introduced design of a new type of control system for free-swing fire monitor. The system has two control modes　of wireless remote control and panel electric control, and can fire extinguishing automatically in wide range. MCU is taken as MPU to process control signals and limit switch signals, and carry out corresponding control action. A wireless remote module is designed and L298 which is driving IC with three routes is used to drive fire monitor to move. The project application result showed that the system has stable running and easy operation with wide application situation.
