可编程控制器在主机遥控报警系统中的应用

Application of Programmable Controllers in Main Engine's Remote Control andWarning System

介绍了在主机遥控报警系统中,可编程控制器作为核心处理单元的应用原理。该系统为气电混合方式,由可编程控制器控制电-气压力调节阀和电磁阀,实现三台主机转速自动控制,齿轮箱正、倒车自动换向控制以及报警监测控制等。可编程控制器的通讯功能将三台主机联系起来,构成了集散控制、集中监视的控制方式。

This paper describes the application principle of programmable controllers used in main engine's remote control and warning system. The mixed system of gas and electricity adopts programmable controller to adjust the gas-electricity pressure valves and electromagnetic valves. Thus the speed control of main engine , the positive and negative adjustment of gearbox and the warning inspect of the system can be automatically achieved in response to our demand. Three main engines are communicated with each other utilizing programmable controller to realize the centralized control and arrangement of the system. The device is advanced and unique.
