发射机自动开关机控制系统设计

Design of Transmitter Automatic on-off Control System

阐述一款发射机自动开关机控制系统。该系统使用KG316T-H微电脑时控开关对继电器进行控制,再通过继电器控制发射机电源的闭合与断开。一旦继电器闭合,发射机电源接通,便会自动开机;继电器断开,发射机电源便会断开,则发射机自动关机。利用该原理,对广播电视发射台的多台发射机进行改造,实现自动开关机功能,对于减轻值班人员的工作压力具有非常重要的意义。

This paper describes a transmitter automatic on-off control system. The system uses KG316T-H microcomputer time control switch to control the relay, and then controls the closing and disconnection of the power supply of the transmitter through the relay.Once the relay is closed, the transmitter will automatically open when the power supply of the transmitter is connected;when the relay is disconnected, the power supply of the transmitter will be disconnected, and the transmitter will automatically shut down. Using this principle to transform multiple transmitters of radio and television transmitting stations to realize the function of automatic switching on and off, which is of great significance to reduce the working pressure of personnel on duty.
