Automatic ascending and descending speed limiting device and control method thereof

Abstract

The invention discloses an automatic ascending and descending speed limiting device and a control method thereof. The device comprises an automatic ascending and descending speed limiting pile and a parallel buried coil sensing strip in mutual connection, wherein the automatic ascending and descending speed limiting pile and the parallel buried coil sensing strip are respectively arranged under a lane; the parallel buried coil sensing strip is used for obtaining the vehicle passing time difference information, and further, the vehicle speed is obtained; the automatic ascending and descending speed limiting pile comprises an outer pile body, an inner pile body, a scissor-fork-shaped connecting rod mechanism and a lead screw transmission mechanism; the outer pile body is fixedly arranged under the lane; an accommodating cavity is arranged inside the outer pile body; the inner pile body is arranged in the accommodating cavity; the inner pile body can ascend and descend; after the inner pile body descends, the top of the inner pile body is flushed with the lane plane; the inner pile body and the outer pile body are connected through the scissor-fork-shaped connecting rod mechanism; the lead screw transmission mechanism is arranged on the scissor-fork-shaped connecting rod mechanism; the top of the inner pile body is provided with a camera. The automatic ascending and descending speed limiting device and the control method have the advantages that the image information of overspeed vehicles can be fast recorded; drivers can be alerted to slow down; the road passing safety environment is effectively maintained.

Description

technical field [0001] The invention relates to the technical field of road safety, in particular to an automatic lifting speed limiting device and a control method thereof. Background technique [0002] Speeding is one of the most important causes of traffic accidents. In recent years, road traffic accidents caused by speeding have become more and more serious, and the situation is very grim. The number of deaths and direct property losses caused by them rank first among traffic accidents, especially in schools, communities, intersections, pedestrian crossings, etc. On special road sections, speeding has extremely high potential safety hazards, and the cost of accidents is also extremely heavy. At the same time, speeding also greatly interferes with the normal traffic flow order. In order to effectively curb speeding behavior, especially on special road sections to strictly prevent speeding behavior, and force drivers to abide by traffic planning, an automatic lifting spe...
