【摘要】：随着我国公路建设的快速发展,隧道越来越多。为了确保运营安全,提高管理效率,必须建立完善的隧道监控系统。通风监控系统是整个隧道监控系统的重要组成部分,其设计目的在于有效管理隧道内的通风设备,及时改善隧道内的通风状况,减少能源消耗,降低运营成本。本论文依托翔安隧道通风监控系统项目,充分考虑隧道通风设计原则,在研究工业以太网、PLC、组态王的基础上,结合项目实际要求,对通风监控系统进行了设计与实现。隧道通风监控系统与隧道监控系统其他子系统既相互独立又相互影响。本文首先阐述了整个隧道监控系统的构成,然后介绍了8个子系统的组成与功能,并着重对通风监控子系统进行介绍。在充分了解系统的设计要求后,给出翔安隧道监控系统的总体设计方案,并对系统的通信网络、区域控制器进行了硬件设计。采用lOOMbps冗余自愈式光纤环形以太网作为监控中心与区域控制器、区域控制器之间的通信网络,区域控制器与现场设备之间则采用现场总线连接。确定区域控制器采用可编程逻辑控制器PLC,并对PLC进行选型,最终选用施耐德M340PLC。利用组态王6.55编写通风监控系统的上位机软件,完成软件功能与界面的设计,并通过ODBC(开放数据库互连)方式实现MS Access与组态王的连接。最后利用施耐德PLC编程软件Unity Pro XL编写通风监控系统的PLC程序。目前,翔安隧道服务洞通风监控系统已调试完成,并在翔安隧道监控中心运行快半年,性能可靠稳定。
[Abstract]:With the rapid development of highway construction in China, there are more and more tunnels. In order to ensure the safety of operation and improve the efficiency of management. The ventilation monitoring system is an important part of the whole tunnel monitoring system. The purpose of its design is to effectively manage the ventilation equipment in the tunnel and improve the ventilation situation in the tunnel in time. This paper based on Xiangan tunnel ventilation monitoring system project, fully consider the tunnel ventilation design principles, on the basis of industrial Ethernet, configuration king. Combined with the actual requirements of the project, the ventilation monitoring system is designed and implemented. Tunnel ventilation monitoring system and other subsystems of tunnel monitoring system are independent and mutual influence. This paper first describes the structure of the whole tunnel monitoring system, and then introduces the composition and function of the eight subsystems. The ventilation monitoring subsystem is introduced emphatically. After fully understanding the design requirements of the system, the overall design scheme of Xiangan tunnel monitoring system is given, and the communication network of the system is also given. The lOOMbps redundant self-healing fiber ring Ethernet is used as the communication network between the monitoring center and the area controller. The area controller and the field equipment are connected by field bus. The programmable logic controller (PLC) is used in the area controller, and the PLC is selected. Finally, Schneider M340 PLC is selected. The upper computer software of ventilation monitoring system is written by Kingview 6.55, and the function and interface of the software are designed. And through ODBC (Open Database Interconnect). Finally, the author uses Schneider PLC software Unity Pro XL to program the PLC program of ventilation monitoring system. At present, the ventilation monitoring system of Xiangan tunnel service tunnel has been debugged and run in Xiangan tunnel monitoring center for nearly half a year, and the performance is reliable and stable.
