Visible light communication-based intelligent transport system, intelligent transport alarm method and intelligent transport vehicle distance maintaining method

Abstract

The invention discloses a visible light communication-based intelligent transport system, intelligent transport alarm method and intelligent transport vehicle distance maintaining method. The visiblelight communication-based intelligent transport system includes a visible light communication unit, a visible light transceiver module disposed on front bodies of a truck and a car, the visible lighttransceiver module disposed at a traffic light, and a central processing module disposed at the traffic light. The visible light communication unit is separately disposed on a vehicle front body and the traffic light, converts transmitted information into a visible light signal to be emitted, and receives the visible light signal and restores original information therefrom, thereby completing transmission and reception of a visible light communication signal. Through a visible light communication link established between a truck fleet and the traffic light, movement information of the truck fleet is transmitted to the traffic signal light in time, and traffic signals in different directions are changed in time after computation to ensure that the truck fleet passes an intersection at a constant speed, and so, vehicle loss caused by deceleration or emergency braking of the truck fleet is avoided, and the occurrence of road traffic accidents is effectively reduced or avoided.

Description

technical field [0001] The invention relates to the application field of intelligent transportation systems, in particular to an intelligent transportation system based on visible light communication, an alarm method, and a vehicle distance keeping method. Background technique [0002] With the rapid development of the social economy and the rapid development of the transportation industry, people's travel methods are becoming more and more convenient. According to relevant statistics, in 2017 alone, the national car sales have exceeded 24 million. The rapid increase in vehicle ownership has brought about a series of problems including traffic accidents, environmental pollution, and urban congestion. Among them, traffic accidents related to trucks (including truck fleets) increased most obviously. Due to the inherent shortcomings of trucks (convoys) such as large mass, difficult braking, and poor vision, it is difficult to slow down or brake in time when an emergency occur...

AI Technical Summary

Problems solved by technology

Due to the inherent shortcomings of trucks (convoy) such as large mass, difficult braking, and poor vision, it is difficult to slow down or brake in time when an emergency occurs, and it is easy to cause various traffic accidents such as rear-end collisions, collisions, and collisions.
