基于PLC的采盐机采掘控制系统设计

The study on control system of salt digging machine based on PLC

主要介绍PLC控制系统的特点以及电气控制系统的应用。该采盐机的电气控制系统是以PLC控制技术为核心的定深自动控制系统,实现采盐机在水中按指定深度挖掘,并自动保持深度,同时控制其他动作及监控采盐机运行状态。

This paper focused on the introduction of the characteristic of the PLC control system and its application on the salt digging machine. The primary part of the electrical control system of the salt digging machine was an depth automatic control system based on PLC technique. When working in the water, this electrical system ensured the digging depth in accord with the prepected value automaticly. It also controled other operations and monitored the machine＇s situation.
