Crossing toll collection device based on visible light communication and toll collection system

Abstract

The invention discloses a crossing toll collection device based on visible light communication. The device comprises a visible light communication device, a controller, a snapshot device and a computer, wherein the visible light communication device is used for achieving data communication between vehicles and a toll station; the controller is used for controlling a lane handrail and a signal lamp; the snapshot device is used for taking candid photographs of the vehicles; the computer is connected with the visible light communication device, the controller and the snapshot device. The invention further discloses a toll collection system of the crossing toll collection device based on visible light communication. The toll collection system comprises a plurality of crossing toll collection devices based on visible light communication, the computers of the crossing toll collection devices based on visible light communication are connected with a switch of the toll station, and the switch is connected with a toll-station server and a database of an expressway system. Ground induction coils do not need to be buried in advance, the visible light communication technology is combined, headlamps of the current vehicles are used fully, erroneous judgment of the vehicles is avoided, and the number of communication dead zones is reduced.

Description

technical field [0001] The invention relates to the technical field of visible light communication, in particular to an intelligent expressway toll system based on visible light communication. Background technique [0002] With its advantages of high speed, safety, and high efficiency, expressways have become important transportation hubs for major cities and cargo transportation in my country. However, with the establishment of my country's highway network and the increase in traffic volume, the defects and deficiencies of the traditional highway toll collection technology (Manual Toll Collection System, referred to as the MTC system) have become increasingly prominent, especially on major national holidays. The overcrowding phenomenon of the highway is relatively serious. How to ensure the channeling function of the expressway, improve the management and service level of the expressway, and speed up the rapid passage and intelligentization of toll stations have become the p...

Problems solved by technology

However, with the establishment of my country's highway network and the increase in traffic volume, the defects and deficiencies of the traditional highway toll collection technology (Manual Toll Collection System, referred to as the MTC system) have become increasingly prominent, especially on major national holidays. The overcrowding phenomenon of the highway is relatively serious. How to ensure the channeling function of the expressway, improve the management and service level of the expressway, and speed up the rapid passage and intelligentization of toll stations have become the primary problems faced by the Chinese government and expressway operating companies.

[0003] At present, in some expressway toll stations in China, non-stop toll collection system (also known as Electronic Toll Collection System, referred to as ETC system) is installed to carry out automatic identification of vehicles and exchange of relevant toll data, and toll collection is carried out through the computer network. The processing of data realizes the full electronic toll collection system of non-stop automatic toll collection, which partially solves the problems faced by the expressway, but the current ETC system has the following problems: it needs to bury the ground induction coil for prompting; the ETC system will have In the case of car-following interference, when multiple vehicles are in the antenna communication area at the same time, it is easy to make a wrong judgment. Due to the directional characteristics of the antenna, there may be a certain communication blind area near the railing; most of the working frequency bands of ETC are 915Mhz, 2.4GHz, 5.8GHz Or other frequency bands, which have a certain degree of radiation; due to the performance differences of vehicle electronic tags and the complexity of vehicle driving behavior (such as entering the ETC lane by mistake), the situation of reversing in the ETC lane is serious, which is likely to cause lane congestion
