Embodiment Construction

[0026] As described in the background art, the traditional tunnel monitoring system adopts a tree structure, and communication links are easily damaged by disasters, which reduces the reliability of the tunnel monitoring system. figure 2 yes figure 1 The schematic structural diagram of the tunnel monitoring system shown when a failure occurs. When the communication link between the monitoring station 1 and the information processing unit 11 fails, the pre-processing unit 111 to the pre-processing unit 113 The monitoring area responsible for cannot be controlled by the monitoring station 1; when the communication link between the information processing unit 12 and the pre-processing unit 122 fails, the monitoring area responsible for the pre-processing unit 122 Cannot be controlled by the monitoring station 1. That is to say, in the existing tunnel monitoring system, there is single-link communication between each information processing unit and the monitoring station 1, betw...

Abstract

The invention provides a tunnel monitoring system which comprises a main monitoring station, a standby monitoring station, M information processing units, and (M-1) pre-processing stages. Each of the pre-processing stages comprises at least two pre-processing units, and M is an integer larger than 1. The main monitoring station and the standby monitoring station are mutually connected and are hot standby of each other. The M information processing units are orderly connected in series, and two adjacent information processing units are hot standby of each other. The first information processing unit is connected to the main monitoring station, and the Mth information processing unit is connected to the standby monitoring station. At least two pre-processing units are orderly connected in series. The first pre-processing unit in the mth pre-processing stage is connected to the mth information processing unit, the last pre-processing unit in the mth pre-processing stage is connected to the (m+1)th information processing unit, and m is larger than or equal to 1 and is smaller than or equal to (M-1). The tunnel monitoring system provided by the invention has the advantages of high reliability, strong self-healing capability and easy extension and maintenance.

Description

technical field [0001] The invention relates to the technical field of monitoring systems, in particular to a tunnel monitoring system. Background technique [0002] With the rapid development of my country's traffic roads, railway and highway tunnel construction projects are increasing day by day. Due to the complex geographical conditions of our country and the characteristics of the tunnel itself, the tunnel monitoring system plays an extremely important role in the operation and management of the tunnel and the handling of accidents. If advanced monitoring and management measures are not adopted, traffic accidents and traffic jams will easily occur in the case of heavy traffic volume and bad weather. Tunnel monitoring and management has become an important guarantee for the safe and normal operation of vehicles in the tunnel. With the development of computer technology, image processing technology, communication technology and control technology, Ethernet technology and...
