输气管道压缩机站的控制必须精确而可靠,这是由于压缩机站可能长期处于无人管理的工作状态。因此,利用远程通信微波线路的远距离压缩机站最好选择可编程控制器(PC)作为主要的控制装量。使用可编程控制器可以减少维修时间,停机时间,以及减少现场接线变化和故障。例如,某一压缩机站的故障可以由装在控制室中的 CRT 终端准确指出,甚至也可以由 The control of the gas pipeline compressor station must be accurate and reliable, as the compressor station may remain unmanaged for long periods of time. Therefore, it is best to choose a programmable controller (PC) as the primary control load for remote compressor stations that utilize telecommunications lines. The use of programmable logic controller can reduce maintenance time, downtime, and reduce field wiring changes and failures. For example, failure of a compressor station may be accurately indicated by a CRT terminal installed in the control room, or even by
