摘要
介绍了四川龙泉山隧道监控系统的构成,及Schneider UnityPremium PLC在该监控系统中的系统架构和控制思想,网络系统以Modbus TCP/IP 100Mbps工业光纤以太环网和GPRS无线网络通讯模块为网络核心。监控系统投入使用以来,运行情况良好,稳定可靠,实现了现场无人值守控制。
The components of Sichuan Longquan Mountain supervisory system in the expressway tunnels are introduced.Schneider UnityPremium PLC's system structure and control method in the supervisory system are also introduced.In this supervisory system,the network core is Modbus TCP/IP 100 Mbps industrial optical fiber nets and GPRS wireless network.Since the proposed supervisory system was applied,its operation has been of good stability and reliability,which realizes the unattended site.
