城市隧道监控系统的设计与实现

Design and Implementation of Urban Tunnel Monitoring System

城市隧道监控系统是隧道机电附属系统中的重要组成部分。隧道监控系统可以实时监测、采集隧道内的数据信息,并将数据上传至管理中心。在过往城市隧道的设计过程中,监控系统只是基于隧道的各个独立系统进行设计,为提高管理与运营的效率,尽量减少交通事故,能够及时处治突发事件,需对隧道各监控子系统进行精细化设计,为各子系统之间的联动预留控制条件,提升多系统联动的兼容性和整体性,实现隧道智能化运行。针对城市隧道的特点,结合雄安某隧道工程实际情况。从隧道内各监控子系统的设置原则和数据传输网络的结构阐述了城市隧道监控系统的设计方案。详细介绍了各监控子系统外场设备的布置原则和使用功能,以及隧道内通信网络的组成结构。

The urban tunnel monitoring system is an important component of the tunnel electromechanical auxiliary system.The tunnel monitoring system can monitor and collect real-time data information within the tunnel,and upload the data to the management center.The monitoring system is only designed based on individual systems of the tunnel in the design process of urban tunnels in the past.In order to improve the efficiency of management and operation,minimize traffic accidents,and be able to handle emergencies in a timely manner.It is necessary to refine the design of various monitoring subsystems in the tunnel,reserve control conditions for the linkage between each subsystem,improve the compatibility and integrity of multi-system linkage,and achieve intelligent operation of the tunnel.This article focuses on the characteristics of urban tunnels and combines the actual situation of a certain tunnel project in Xiong’an.This paper elaborates on the design scheme of urban tunnel monitoring system from the principles of setting up various monitoring subsystems in the tunnel and the structure of data transmission network.Detailed introduction was given to the layout principles and usage functions of the external equipment of each monitoring subsystem,as well as the composition structure of the communication network inside the tunnel.
