摘要
PLC是一种计算机系统,比一般计算机具有更强的与工业过程相连接的输入输出接口,已基本取代了传统的继电器和接触器的逻辑控制,并成为自动化控制系统的基本装置。主要介绍了PLC控制在全自动粮库控制系统应用及相关硬件电路、软件的设计。
PLC is a kind of computer system. It has stronger I/O interface to connect with industrial process compared to the common computer and has basically substituted of the logical control of traditional relay and contact devices, thus become the basic installment in automation control system. In this article, the PLC control in the automatic grain storage control system and the correlation hardware electric circuit as well as the software design are mainly introduced.
