Intelligent anti-collision guardrail, system and method suitable for long and large downhill of mountainous highway

Abstract

The invention discloses an intelligent anti-collision guardrail, system and method suitable for long and large downhill of a mountainous highway. The intelligent anti-collision guardrail comprises connecting stand columns, guardrail plates and a flexible protective net. The connecting stand columns are buried in the positions, needing guardrails, of the road side, and sliding rails are arranged onthe surfaces of the connecting stand columns. The guardrail plates are located between the adjacent connecting stand columns, and the two ends of the guardrail plates are connected with the sliding rails on the surfaces of the connecting stand columns respectively. The guardrail plates are divided into an upper guardrail plate, a middle guardrail plate and a lower guardrail plate, the upper guardrail plate and the lower guardrail plate are equal in width, and the middle guardrail plate is wider than the upper guardrail plate or the lower guardrail plate; the flexible protective net is arranged between the upper guardrail plate and the lower guardrail plate, when the anti-collision device is not started, the flexible protective net is in a folded state, the service life of the anti-collision device can be prolonged, and the use cost of the anti-collision device is reduced; when the anti-collision device is started, the upper guardrail plate can slide in the direction of the sliding rail, the flexible protective net is opened, and the safety accidents that a running vehicle rushes out of a road and turns over under strong impact can be effectively prevented and reduced.

Description

technical field [0001] The invention relates to the technical field of road safety, in particular to an intelligent anti-collision guardrail, a system and a method suitable for growing and descending slopes of mountain roads. Background technique [0002] In recent years, the low-grade roads in mountainous areas, especially the long downhill sections, due to the low road grade, poor horizontal and vertical indicators, and serious road damage, frequent traffic accidents on the downhill section of the car, or damage to the car, resulting in traffic jams ; Seriously, roll over, rush out of the road and roll down the slope, causing major casualties. This situation is not uncommon on mountainous roads. [0003] The main reasons for this situation are as follows: 1) mountainous roads are limited by terrain conditions, the road level and longitudinal indicators are poor, and the design speed is low, and passing vehicles often exceed the design speed; 2) the roads are narrow and the...
