Beidou satellite-based mountainous area bend vehicle anti-collision alarm method and system

Abstract

The invention discloses a Beidou satellite-based mountainous area bend vehicle anti-collision alarm method and system. The method includes the following steps that: after vehicles enter a mountainous area, and the position and speed information of the vehicles is obtained through Beidou positioning; latitudes and longitudes are converted into a Gaussian plane coordinate system through coordinate transformation, a distance between the two vehicles is calculated; and when the two vehicles are too close, collision risk state estimation is performed, and alarm signals are emitted according to alarm rules. According to the Beidou satellite-based mountainous area bend vehicle anti-collision alarm method and system of the invention, information such as the position and speed information of the vehicles is measured in real time through the Beidou satellite, the operating states of the vehicles in a bend are calculated, and the collision risk state of the vehicles in the bend is estimated, and the effective alarm of the vehicles in the bend of the mountainous area can be realized.

Description

Technical field [0001] The invention belongs to the field of Beidou satellite positioning application systems, and in particular relates to a method and system for preventing collisions of vehicles on curved roads in mountainous areas based on Beidou satellites. Background technique [0002] With the vigorous development of the automobile industry and the improvement of people's living standards, the number of private cars is increasing, but traffic accidents are also increasing year by year. Among them, although the proportion of traffic accidents in mountainous areas is small, the casualties are the most serious. Mountains and hills in our country account for 70% of the total land area. The construction of mountainous roads is increasing. The mountainous terrain is steep and the corners are sharp. The probability of vehicle accidents in the mountains is relatively high. The characteristics of mountain traffic accidents are high casualties and late alarms. Prone to cause second...

AI Technical Summary

Problems solved by technology

When the vehicle is driving on a mountain curve, because the special terrain of the curve blocks the driver's sight, the driver cannot accurately judge whether there is a vehicle coming in front, which increases the possibility of an accident on the curve

At present, the most extensive preventive measure is to place convex mirrors at the corners to increase the driver's sight range, but at the same time it will affect their attention, and the effect is limited, so a new type of measure is needed to improve this

On the other hand, due to poor signal, untimely alarm and hidden vehicles, it is difficult to carry out rescue work in time after the accident.
