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 information immediately, and the drivers behind are still too late to deal with it;
[0037] (2) This vehicle-mounted machine must be equipped with a large power to communicate with the center wirelessly. In order to send and obtain information as soon as possible, the wireless transmission circuit must be in a high-power transmission state at all times, so its battery capacity and volume make it impossible for the vehicle-mounted machine to communicate with the center. Enter the practical level
[0041] Disadvantages: Same as the previous example, the response speed cannot be guaranteed, and the battery capacity and the size of the "card" cannot be practical
[0044] Disadvantages: It is required to install a large number of detection devices on the guardrail along the expressway, and its energy, cost and maintenance cannot reach the practical level
[0045] To sum up, at present, there is no technology in China that can comprehensively and effectively solve the problem of highway traffic accidents, which is actually a technical blank

Embodiment Construction

[0087] A typical implementation case of a kind of road traffic accident prevention and control device of the present invention is illustrated as follows:

[0088] see figure 1 , This road traffic accident prevention and control device includes a single-chip microcomputer 1 and a GPS positioning module 2 connected thereto, a wireless transceiver module 3, a collision sensor 4, a voice reminder module 5, a display module 6, a power module 7 and an alcohol sensor module 8. The wireless transceiver module adopts modern ad hoc low-power wireless sensor network modules, such as ZigBee, which can communicate with each other. Obtain position information through GPS positioning module, communicate with other on-board devices and vehicle entrance and exit processing devices through wireless transceiver module, collision sensor detects vehicle collision and other information, voice reminder module provides voice information to drivers and passengers, and displays it to drivers and passen...

Abstract

A road traffic accident prevention and control device is composed of 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 vehicle distance, vehicle speed, abnormal parking calculation and processing module, a collision perception and processing module, a voice and display reminder module, and mutual information transmission modules. The present invention can effectively prevent and control malignant traffic accidents on modern highways, and can directly send accident information to follow-up vehicles in a very short time to prevent serial collisions, and continue to send information to various toll stations and management centers, and timely Rescue measures are 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...
