Intelligent visibility detection equipment for traffic safety monitoring of tunnels

Abstract

The invention relates to intelligent visibility detection equipment for traffic safety monitoring of tunnels. The intelligent visibility detection equipment comprises a telescopic mechanism, an emitter, a receiver and two movable mechanisms, wherein each movable mechanism comprises a movable platform, a lifting mechanism, a lifting platform and a drying mechanism, the lifting mechanism comprises afixed block, a movable block, a driving unit and a telescopic frame, and the drying mechanism comprises a direction adjusting mechanism, a spraying head, an air guide pipe and a drying box. Accordingto the intelligent visibility detection equipment for the traffic safety monitoring of the tunnels, the distance between the two movable platforms is changed by virtue of the telescopic mechanism, the height positions of the lifting platforms are changed by virtue of the lifting mechanisms, and the emitter and the receiver can be subjected to visibility detection at different positions, so that the detection range of the equipment is substantially increased; and furthermore, hot air is conveyed by virtue of the drying boxes, the angles of the spray heads are adjusted by virtue of the direction adjusting mechanisms, and water mist on mirror surfaces of the emitter and the receiver is evaporated, so that the visibility in the tunnels can be accurately detected by virtue of the equipment incloudy and rainy weather.

Description

technical field [0001] The invention relates to the field of tunnel monitoring equipment, in particular to an intelligent visibility detection equipment used for tunnel traffic safety monitoring. Background technique [0002] Visibility, also known as visibility, refers to the maximum distance at which an observer can clearly see an object under normal vision, and is usually equivalent to the "sight distance". Visibility is widely used in surface road tunnels. If the visibility is too low, the driver will easily make mistakes in judging the obstacles and pedestrians ahead, which will affect the intuitive feeling of orientation, positioning, confirmation of distance and speed feeling during driving in the tunnel. In road tunnels, visibility is the main factor that must be considered in normal operation and in fire accidents. At present, people usually use CO / VI detectors to detect the visibility inside the tunnel. [0003] However, because the existing visibility detection...

Problems solved by technology

[0003] However, because the existing visibility detection equipment is fixedly installed inside the tunnel and the height position is fixed, the equipment can only detect the visibility at a specific height within a certain range inside the tunnel, resulting in a very limited detection range. Not only that, In rainy weather, due to the substantial increase in the humidity in the air, some water mist is easily adsorbed on the mirror surface of the transmitter and receiver, resulting in large deviations in the results of equipment detection, which brings certain hidden dangers to tunnel traffic safety. Causes the practicability of the existing visibility detection equipment to be reduced
