数传电台在工业控制中的应用

The Application of Radio in Modem in Industrial Control

在工业控制领域中,存在一些通讯距离较远、通讯电缆难以敷设、无人职守等控制站,而这些控制站又需要在中控室内集中监视设备的工作状态及远程操作,数传电台可以很好地解决这种远程监控的问题.在中控室内设有主电台,远程站内设有从电台,控制指令通过主电台以无线通信的方式发送到从电台来控制远程站设备,远程站的设备状态通过从电台以无线的方式发送至中控室内的主电台来监控远程站的设备状态;数传电台的应用解决了一些远程控制系统敷设通讯电缆困难或通信距离较远的情况,实现了对远程系统实时监控及数据采集,从而提高了系统的运行可靠性.

In the field of industrial control,there are some control stations which are with long distance communication,difficult for communication cable laying or have no one on duty etc.However,thesecontrol stations need to monitor the working status and remote operation ofthe equipment in the central control room.The digital communication radio could solve the problem ofremote monitoring very well.The master communication radio is located in the main control room and the slave communication radio is located in the remote station.Through the main digital communication radio.control commands are sent to the slave digital communication radio at the way of wireless communication to control the equipment in the remote station.And the status of equipment in the remote station is sent to the main digital communication radio in the central control room to monitor the equipment status in the remote station through the slave digital communication radio.The application of digital communication radio solves the problems of difficulties in communication cable laying of some remote control systems or having a long communication distance,realizes the renl-time monitoring and data collection of the remote system,and improves the operation reliability of the system.
