Design of a Novel Free Swing Fire Monitor Control Circuit

Abstract

The free swing fire monitor is suitable for the situation which is too risk to access for fireman. The fire monitor control system designed in this thesis has two control modes, wireless remote mode and panel control mode. So fireman can use it far from the dangerous fire field to aim at the fire and make it swing in a certain range. In this system, a MCU is used to process the control signals and limit switch signals, and give the control signals to DC motor correspond. The send/receive modulation TDA5101/TDA5211 is used in wireless remote-control unit and driver IC L298 is used to drive the DC motor. The design process and the scheme of the control system are present. The designed fire monitor is verified in practice. It is tested in practice that the designed fire monitor is reliable, simply and widely used. It is the first choice fire devices of all kinds of Fire agent. which are wireless remote control and panel keystroke control are designed in this fire monitor. The sector area of Free Swing is designed to be three different gears according to different needs. That is to say, the Free Swing operating has three gears. In this paper, driving circuit of DC motor, electric control and wireless remote control circuit, and control system of fire monitor are designed. The design process and scheme is illustrated. The designed fire monitor is field-tested. The result of field-testing show the designed fire monitor can free the fireman from operating fire branch and fire monitor for long time which is the first choice of military fire service, private fire brigade, and industry of Petroleum. The equipment possesses the advantage of great range, easy and flexile to use, altitude and minus angle definite is beneficial to fireman to keep away from dangerous case.
