System and method for cab avoidance of vehicles of highway green detection channel

Abstract

The invention relates to a system and a method for cab avoidance of vehicles of a highway green detection channel. The system comprises a first group of sensor nodes, a second group of sensor nodes, a third group of sensor nodes, a ray generator, a ray detector and a controller, wherein each group of sensor nodes consists of a pair of light pillars, each pair of light pillars is provided with three pairs of photoelectric switches, the controller is used for preprocessing the vehicle information, the vehicles are classified into trailer vehicles and non-trailer vehicles, and a proper time is obtained by analysis and judgment to open and close the ray generator. The system and the method have the advantages that the problem of the cab avoidance of the detected vehicles of the highway green detection channel is solved, the safety of driving persons is ensured, the efficiency is high, the cost is low, and the practicality is high.

Description

technical field [0001] The invention belongs to a control system and a corresponding discrimination method in the field of expressway green passage detection, in particular to an expressway green detection passage cab avoidance system and a corresponding avoidance method. Background technique [0002] In order to establish a smooth and convenient circulation network of fresh and live agricultural products, the state has carried out the construction of green passages on expressways, and vehicles that meet the requirements of green passages will be exempted from tolls. However, some vehicles exploited national policies and used methods such as mixing and disguising to evade expressway tolls. For the inspection of green pass vehicles, the inspection is traditionally carried out manually. This inspection method has low work efficiency and cannot achieve a good inspection effect. [0003] At present, the main methods of expressway green channel inspection are sensory method, ton...

Problems solved by technology

[0004] Although ray perspective technology is a fast and efficient non-destructive testing method, which can well solve the problem of difficult detection in the existing green channel, but for the commonly used X-rays, γ-rays and Co-60, no matter which ray is used will cause harm to the human body

When the ray is directly irradiated to the human body, although the radiation dose of one ray exposure is very small, it will inevitably cause harm to the human body with the increase and accumulation of the number of ray exposures.
