Problems solved by technology

[0006] The purpose of the present invention is: to overcome the following defects of the existing vehicle early warning method: adopt GPS to obtain the geographical position information of the vehicle, but can only display the bearing of the accident vehicle, can not show the concrete position of all vehicles, provide a kind of vehicle early warning based on view method, which can monitor all vehicle movement conditions in a large area on the highway (especially the expressway), provide early warning information for vehicle drivers who may collide, and avoid accidents

Embodiment Construction

[0064] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0065] The view-based vehicle early warning method of the present invention is characterized in that:

[0066] (1) Perceive all vehicle status information in the highway detection section, these information are: use GPS to obtain all vehicle position information in the highway detection section, use vehicle instruments to obtain all vehicle speeds, and use vehicle transmission devices to obtain all vehicle braking, acceleration, and turning information;

[0067] (2), assigning a unique identification number to the vehicle, and assigning a sending data list to the vehicle;

[0068] (3) Generate views of all vehicles in the road detection section.

[0069] (4) Early warning and warning information dissemination of rear-end collision accidents.

[0070] Referring to Figure 1, the software framework of vehicle early warning includes four parts: information per...

Abstract

The invention relates to a vehicle prewarning method based on view, comprising vehicle information-perceive step, view-generating step, tailgate-prewarn step and alarm information-propagate step, as well as the step of obtaining the information of vehicle position, speed, brake and acceleration by peripheral equipment, the step of distributing a unique mark number and the step of distributing a transmitting data list for the vehicle. The steps enable the vehicle information to form view form and reflect the current state of surrounding vehicle timely, therefore can precompute the likely tailgate and alarm the driver, and then propagate the information out; at last the vehicle can receive the accident information in specified range. The invention has the advantages of wide perceiving range, short prewarning response time and high coverage rate, therefore the safety of the vehicle on the motorway can be improved.

Description

technical field [0001] The invention relates to the technical field of wireless network communication, in particular to mobile ad-hoc network technology, in particular to a vehicle network security early warning method. Background technique [0002] Statistical data and research data show that my country has entered a period of high incidence of road traffic accidents, and the situation of road traffic safety is very severe. According to the national road traffic accident situation announced by the Ministry of Public Security, there were 27,788 road traffic accidents in April 2007, resulting in 6,349 deaths, 32,246 injuries, and direct property losses of 90 million yuan. Comparing horizontally with other countries, the number of traffic accident deaths in my country ranks first in the world. [0003] Reducing the losses caused by traffic accidents is a major problem faced by all countries in the world. For a country like my country, which is vigorously developing road traff...
