Embodiment Construction

[0011] figure 1 The use of wireless self-organizing network technology to realize the automobile collision avoidance method flow on the highway, the steps are as follows:

[0012] Step S1, install an electronic device that supports mobile IPv6 network functions and ad hoc communication in the car, and assign it an IPv6 address, wherein the ad hoc communication is realized between the front and rear cars through directional antennas installed in the front and rear of the car Information communication, the car itself can realize the interconnection with the Internet and traffic management communication network through wireless mobile IPv6;

[0013] Step S2, when the car is driving on the expressway, the vehicle-mounted IPv6 wireless transceiver device communicates with the front and rear cars in an ad hoc manner through the directional antennas placed in front of and behind the car, and exchanges the driving speed of each car, the operating status of the car, etc. ;

[0014] S...

Abstract

A method for using wireless self-organizing network technique to prevent collision of car on expressway includes installing an electronic device in car, which supporting mobile IPv6 network functions and self-organizing communication, communicating in self-organizing mode, generating warning information, judging if the distance reaches the warning value, generating warning information, and sending the collision accident to relative department via wireless network if a rear collision occurs.

Description

technical field [0001] The present invention relates to the field of communication network technology and intelligent transportation technology, in particular to a method of realizing automobile collision avoidance and The automatic alarm method after the accident occurs, thereby effectively avoiding the occurrence of major traffic accidents on the expressway. Background technique [0002] In recent years, with the large-scale construction of the expressway network in the country, major traffic accidents on the expressway also occur from time to time, among which the serial collision of multiple cars colliding with each other is the most serious type of accident on the expressway. At present, there is no good way to prevent such accidents from happening. The present invention is to utilize Internet technology, especially mobile IPv6 technology, self-organizing network technology, GIS technology, etc. to jointly prevent the occurrence of such accidents.
