Tunnel disaster pre-warning system based on SCADA technology

Abstract

The invention provides a tunnel disaster pre-warning system based on an SCADA technology. The tunnel disaster pre-warning system comprises a field-level data collecting system, a field foreign matterprotection system and a work-area-level monitoring system. Simulating signals collected by the field-level data collecting system are transmitted to the work-area-level monitoring system to be displayed in real time and meanwhile compared with limiting values of various parameters set by a control interface of the work-area-level monitoring system. If the simulating signals exceed the limiting values, the work-area-level monitoring system drives an audio frequency alarming module to start the field foreign matter protection system for active protection simultaneously. According to the tunnel disaster pre-warning system based on the SCADA technology, existing tunnel disaster prevention and rescue equipment is utilized to be combined with a remote automatic control technology so as to builda railway tunnel disaster prevention and rescue equipment monitoring system, the state of a construction area of a railway tunnel is monitored remotely in real time, automatic alarming is conducted when the danger is found, meanwhile operation of related equipment can be remotely controlled, and the emergency field rescuing function is achieved.

Description

technical field [0001] The invention relates to the technical field of early warning systems, in particular to a tunnel disaster early warning system based on SCADA technology. Background technique [0002] my country's railway system has undergone several major speed increases, especially the gradual construction and operation of the national high-speed railway network. How to ensure the safety of the track in the train running interval is of great importance. At the same time, with the leap-forward development of the railway transportation industry, the requirements for various safety work are also constantly increasing, and all work is carried out around "safety and punctuality". However, railway lines, especially high-speed railways, present the characteristics of a large number of super-large tunnels and long mileage. Therefore, it poses a huge challenge to the active protection of large and long tunnel construction areas and the protection of foreign objects in tunnels...
