介结了一种对多个PLC控制对象进行远程集中监控的设计方案。采用一台现场工控机对同一工作现场的多个PLC控制对象进行集中监控，采用调制解调器和电话线使控制中心微机和现场工控机进行通信，从而实现控制中心的远程集中监控。
Mediated a design of multiple PLC control objects for remote centralized monitoring. A field IPC was used to monitor multiple PLC control objects at the same working site. The modems and telephone lines were used to communicate with the control center microcomputer and field IPC in order to realize remote centralized control of the control center.
