在微机远程测控系统中,子站较多、数据量不大、实时性要求也不高的情况是常见的。这时通讯控制若采用串口加 MODEM 的结构,不但造价高、硬设备多,可靠性也会下降。对此作者研制了 STD 一对多远程容错通讯控制计算机,该机结构新颖并具有一定的容错能力,在矿区电网远程测控系统中得到了成功的应用。
In the computer remote monitoring and control system, substation more data is not large, real-time requirements are not high is common. At this time if the communication control using MODEM serial structure, not only high cost, hard equipment, reliability will decline. To this end, the author has developed a STD one-to-many remote fault-tolerant communication control computer which has a novel structure and a certain degree of fault tolerance. It has been successfully applied in the remote monitoring and control system of power grids in mining areas.
