Variable repetitive rate limiting system for highway construction working area

Abstract

The invention discloses a variable repetitive rate limiting system for a highway construction working area. The system comprises four pressure sensors, two traffic flow speed detectors, a microprocessor, two speed limitation boards, two flash warning lights and two alarming horns, wherein the microprocessor judges the vehicle model through the first pressure sensor, the second pressure sensor, thethird pressure sensor and the fourth pressure sensor, and detects the vehicle speed through the first traffic flow speed detector and the second traffic flow speed detector, controls the first flashwarning light, the second flash warning light, the first alarming horn and the second alarming horn in different modes for the vehicle model and the vehicle speed, reminds a driver to slow down and reminds a construction worker to actively avoid danger. Compared with the prior art, the variable repetitive rate limiting system for the highway construction working area can not only greatly reduce the speed of a vehicle passing through the construction working area, but also improve the protection effect on the construction worker.

Description

technical field [0001] The invention relates to the field of road traffic safety facilities, in particular to a variable and repetitive speed limiting system in an expressway construction work area. Background technique [0002] With the continuous development of expressway construction, reconstruction, expansion and maintenance operations have gradually increased, and the accompanying safety problems have also shown an increasing trend. Limiting the speed of vehicles is one of the main methods to ensure the safety of expressway work areas. Our country's regulations and researches focus on the warning zone as the main section of the speed limit. According to measures, a high proportion of vehicles passing through the work area are still speeding, and large trucks are also one of the major causes of traffic accidents in the construction work area. Therefore, setting the necessary variable speed limit means according to different vehicle speeds in the work area can reduce the...
