Design and Implementation of Urban Tunnel Monitoring System
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.
