Application Of Incident Detecter In Highway Tunnels Monitoring System

In northwestern Guangxi,mostly belonging to the Karst landform,steep mountain tunnels,long tunnels,everywhere,because of the unique tunnel driving environment and effect of illumination difference,traffic space and other factors,resulting in tunnel traffic accidents have occurred,and the tunnel when the accident occurred,the work surface for cranes,trailers,to rescue is very difficult.In the process of expressway operation and management,how to deal with tunnel emergencies quickly,avoid further deterioration and ensure tunnel safety is a major difficulty for tunnel safety management.The manager can monitor the driving status of the tunnel in real time by the tunnel monitoring system,and cooperate with other electromechanical systems to operate the tunnel's lighting,ventilation and fire protection facilities,so as to ensure the safe driving environment of the tunnel.But the centralized monitoring generally take intensive highway tunnel current mode,monitor a limited number of video images,not will be monitoring the implementation of each tunnel picture,in order to fully monitor tunnel,often only take artificial tour the way round,prone to blind tunnel monitoring,affect tunnel monitoring timely,leave risks to the safety management of the tunnel.The event detection system transmits the video signal to the event detector to analyze the traffic incident.The event detector through a series of algorithms,determine the video section whether the occurrence of abnormal events and make equipment linkage,a series of alarm to the operator on duty to respond fast,coordinated management of Expressway parties timely disposal of highway tunnel traffic incident.Based on the application of the event detector in Hechi to Douan highway tunnel monitoring in the role of the event detector in tunnel monitoring system obviously,can automatically and timely detection of traffic incidents in the tunnel,eliminates the blind spot real-time monitoring of tunnel monitoring system,effectively improve the safety of highway emergency management response and disposal efficiency,make the beneficial exploration for the highway intelligent traffic management.
