Full-range real-time monitoring early warning and guiding system for expressway agglomerate fog

Abstract

The invention provides a full-range real-time monitoring early warning and guiding system for expressway agglomerate fog. A visibility collecting module comprises a plurality of agglomerate fog information collecting units arranged along an expressway and is used for analyzing images obtained by the agglomerate fog information collecting units so as to obtain visibility values. An information releasing module is used for displaying a speed limit corresponding to the visibility value according to the visibility value corresponding to the visibility collecting module. A roadside guidance unit isresponsible for identifying and actively guiding moving vehicles. According to the invention, vehicle driving speed limit values of an agglomerate fog area can be released to expressway traffic usersefficiently and effectively in real time according to generation and development condition of agglomerate fog and active guidance of the vehicles can be realized according to guidance to the roadsideguidance unit. Therefore, driving safety is ensured, traffic accidents caused by the sudden agglomerate fog in the expressway can be effectively reduced and prevented, so that the safety service level and operation efficiency of the expressway are improved.

Description

technical field [0001] The invention belongs to the technical field of traffic safety, and in particular relates to an expressway fog early warning and guidance system for full-range real-time monitoring. Background technique [0002] In recent years, many expressway traffic accidents caused by group fog have fully demonstrated the great harm of group fog to highway traffic safety. Highway accidents caused by group fog are often very serious, which poses a great threat to the lives and properties of the general public. Therefore, the early warning and induction system of group fog on expressways should be established to reduce the impact of group fog weather on highway traffic safety and guide vehicles to drive safely in group fog areas, thereby reducing and effectively preventing highway traffic accidents and ensuring the protection of the general public. The safety of people's life and property is of great significance. [0003] At present, my country's expressway cloud ...

AI Technical Summary

Problems solved by technology

First of all, most of the meteorological monitoring equipment in our country is imported from abroad. The equipment is relatively expensive and difficult to maintain; secondly, the design and layout of the outfield equipment is not reasonable enough. Due to the lack of thorough and detailed investigation, research and discussion of factors such as climate, weather and climate, the layout position and layout density of field equipment such as variable information signs and visibility meters cannot reach the actual application effect, so the collected data loses availability and authenticity

In addition, due to improper use and maintenance of weather monitoring and other related equipment, many meteorological monitoring equipment do not really play their due role
