A kind of highway traffic accident prevention and control internet of things and method

Abstract

An internet of things for prevention and control of road traffic accidents, consisting of a management center processing device, a vehicle entrance and exit processing device, and a vehicle-mounted wireless sensor device, the latter including a single-chip microcomputer, a GPS module, a wireless transceiver module, a collision sensor, a voice and display reminder module, and the like. A road traffic accident prevention and control method, comprising a management center processing module, a vehicle entrance and exit processing module, and a vehicle-mounted wireless sensor processing module, the latter including a vehicle distance, vehicle speed, abnormal parking calculation and processing module, collision perception and processing module, voice and Display reminder module, exchange information module and so on. The present invention can effectively prevent and control malignant traffic accidents on modern highways, and can directly send accident information to follow-up vehicles within a very short time after accidents occur to prevent serial collisions, and continue to send information to various toll stations and management centers, and timely Rescue measures can be taken to remind the driver of the distance and speed of the vehicle in time, effectively avoiding the occurrence of vicious traffic accidents on the expressway.

Description

technical field [0001] The invention relates to the field of traffic safety, especially expressway traffic safety. Background technique [0002] We have built highways at a high price, which has brought us unprecedented convenience in travel and logistics. However, according to statistics from the Traffic Management Bureau of the Ministry of Public Security, the accident rate and death rate per 100 kilometers of expressways are 4 times and 2 times that of ordinary highways respectively. [0003] It can be seen that it is an indisputable fact that vicious traffic accidents on expressways occur frequently. Once they happen, it is very easy to cause a series of car accidents. The situation is extremely serious, which has a serious impact on traffic and has become a world-class problem! [0004] According to the statistical analysis of relevant departments, the main reasons for the frequent occurrence of vicious traffic accidents on expressways are as follows: [0005] Sever...

AI Technical Summary

Problems solved by technology

[0024] One is that manual (or software) scanning of thousands of monitoring points is not realistic at all

[0025] Second, manual (or software) glances are prone to misjudgment

[0026] Third, the response speed is slow

[0027] Fourth, it is impossible to notify the follow-up vehicles of the incident in time

[0036] (1) The necessary information can only be obtained through long-distance communication between the vehicle-mounted machine and the monitoring center, and the response speed is slow, especially this kind of wireless communication can only use the existing mobile communication network (such as GSM, GPRS, 3G) from a practical point of view Because the expressway is often hundreds of kilometers long, it cannot be realized without using the mobile communication base stations that have spread all over the world, and its network communication speed is difficult to guarantee (you will experience it when you use it to surf the Internet), so for the follow-up vehicles when the accident occurs It is difficult to obtain accident i
