二次滤网自动控制系统PLC改进并纳入DCS监控

The PLC Reform of the Secondary Strainer Automatic Control System and the Introduction of DCS Monitoring

论文简述二次滤网工作过程,针对运行中存在的问题,对原控制系统提出了相应的改进方案,设计了PLC自动控制逻辑,在分散控制系统中进行了逻辑和画面组态,实现二次滤网的自动控制及远程监控,提高了二次滤网工况的稳定性、可靠性。

The paper briefly describes the working process of the secondary strainer. In view of the problems existing in its operation, the corresponding improvement scheme to original control system is put forward. The automatic control logic of PLC is designed, and the logic and picture configuration are carried out in the decentralized control system. The automatic control and remote monitoring of the secondary strainer are realized, and the stability and reliability of the secondary strainer are improved.
