试论宝天高速公路东段隧道中央控制系统组网方式

On the Eastern Tunnel of Baoji to Tianshui Highway Central Control System Networking

隧道中央控制系统由现场控制网络和隧道现场监控设备组成。隧道控制网络主要由隧道左、右洞内的PLC控制器,变电所内的PLC控制器,工业以太网交换机和光缆网络等组成。分析和论述了宝天高速东段隧道交通监控系统组网及其控制方式,希望对公路隧道监控的运营和发展起到一定作用。

The control system consists of a central tunnel control network site and tunnel-site monitoring equipment. Tunnel control network mainly by the tunnel left and right inside the cave PLC controller, PLC controller inside the substation, industrial Ethernet switches and fiber optic networks and other components. Analysis and discussion of the eastern tunnel traffic monitoring and control system network of Baoji to Tianshui highway, we want to monitor the operation and development of highway tunnels played a role.
