摘要
本文介绍 PLC在隧道自动化中的应用 ,采用现场总线 + PLC+中央控制计算机的集成方案 ,对隧道机电设备进行分散控制和集中管理 ,同时对洞内环境和机电设备进行监测 ,既满足高速公路隧道对洞内照明和通风的控制要求 ,又达到整个系统的协调和节能目的。
This paper describes the application of PLC to the automation of a tunnel. The control system consists of a PLC system, central computer and fieldbus so that the lighting and ventilation can be put under distributed control and concentrated menagement. Such an integrated scheme not only satisfies various control requirements,but also achieves the aim of good coordination and energy saving.
