Highway traffic abnormal event early warning method based on NFC and system thereof

Abstract

Provided is a highway traffic abnormal event early warning method based on NFC, comprising: 1) connecting a handset client and an NFC label, and connecting a server side with an alarm lamp, a fog lamp and an information notice board; 2) when entering a high speed road, reading information into a database, and recording initial information; 3) in case of a traffic abnormal event, sending information to the server side; 4) the server side analyzing and processing event information, and sending early warning information; 5) sending the early warning information to management personnel, and displaying the early warning information in the server side; 6) after processing, the server side sending an information instruction, and recovering vehicle pass; and 7) in case of extreme weather, lightening the fog lamp and guiding safe pass. In the early warning method, the NFC label of the handset client is internally provided with a data collection module which is in connection with a communication satellite, a communication module, the server side, an early warning device node and an early warning device; the early warning method can timely discover an abnormal event, timely take emergency rescue measures, and reduce casualties and loss.

Description

technical field [0001] The invention belongs to the technical field of expressway abnormal event early warning, and in particular relates to an NFC-based early warning method and system for expressway abnormal traffic events. Background technique [0002] Since the beginning of the 21st century, my country's expressways have entered a period of rapid development. As of 2013, the total mileage in traffic has reached 104,468 kilometers, making it the largest expressway system in the world. Expressways have also become an important symbol to measure a country's transportation modernization. The development of expressways has effectively promoted the development of our country's economy and guaranteed our country's security and social stability. [0003] However, in recent years, with the improvement of people's living standards in our country and the rapid development of the car industry and transportation, it is inevitable that the traffic volume of expressways will increase....

AI Technical Summary

Problems solved by technology

[0008] In 2004, Hu Tiehong’s research results on expressway rear-end collision and side collision warning system model showed a new type of vehicle collision avoidance warning system; in 2005, Shao Zufeng introduced the road traffic safety warning technology into the theoretical method of urban traffic management, designed In 2006, Yu Rende and others divided the expressway safety early warning system into crisis judgment, road traffic Prediction forecast, road traffic safety evaluation and alarm four subsystems, on the basis of comprehensive analysis of early warning related theories, put forward the structural framework and construction steps of the early warning system; Evaluation and Early Warning Research also proposed some analysis of the ecological environment of the road area and some indicators for the early warning system, but did not propose a specific early warning plan; RFID technology and the early warning system model and specific architecture of the controller LAN, and analyzed the working principle and key technologies of the system

In addition, the receiving end can also feed back the road condition information to the traffic command center in time through wired or wireless communication means, which can be used as a reference for the traffic command center to command driving. However, this project is still in the state of research and development, and has not been practically applied

[0010] To sum up, the research on early warning theory of expressway traffic safety in China started relatively late. Although the theoretical research on traffic early warning has been carried out, the research content is single and the complete early warning system theory has not yet been formed. Less involved, most of the schemes have not been applied in engineering practice

At present, the research on highway safety mainly includes the research on highway safety early warning system from mountainous roads, ecology, meteorology, etc. The highway safety early warning system has not yet been studied from the perspective of traffic flow theory.
