A vehicle collision avoidance method based on satellite navigation system, navigation system and application

Abstract

The invention discloses a vehicle anti-collision method based on a satellite navigation system and a navigation system and application thereof. A novel vehicle anti-collision method is developed on the basis of the positioning and communicating functions of a Beidou system. The method comprises the following steps of: arranging navigation, communication, emitting and receiving antennae and navigators on more than four vehicles respectively, and performing radio signal connection on the navigation, communication, emitting and receiving antennae and Beidou satellite system emitting and receiving antennae in a positioning and communicating way; receiving and processing signal emitted by the Beidou satellite system emitting and receiving antennae by using the navigators of the vehicles; performing signal amplifying and computing and data processing with the navigators and displaying information such as navigation maps of the vehicles, the position of a certain vehicle and the like on display, alarm and operation panels; and realizing the communication function of a Beidou satellite system to realize an anti-collision alarm function of each vehicle.

Description

technical field [0001] The invention relates to a vehicle anti-collision method and device, in particular to a vehicle anti-collision method and a navigator based on the Beidou satellite navigation system, which are mainly used for vehicle driving monitoring. The invention also relates to an application based on the Beidou satellite navigation system. Background technique [0002] Vicious traffic accidents caused by heavy fog, heavy rain, and dark conditions are affected, and the car cannot find the vehicle in front in time. The nature of the accident is also extremely serious. An example of a series of collisions of hundreds of cars on the highway. [0003] In order to prevent this phenomenon, many anti-collision technical solutions have been proposed. At present, the existing car anti-collision devices are mainly designed by ultrasonic, infrared, and laser radar detection. The common disadvantages are: [0004] 1. The detection distance is too short, only a distance of m...

AI Technical Summary

Problems solved by technology

[0004] 1. The detection distance is too short, only a distance of more than ten meters to tens of meters, leaving too little time for the driver or automatic braking to react. It is only suitable for use in the city and when the speed is very low. Less than anti-collision effect

[0005] 2. The detection angle is small, and the detection effect on curves and side vehicles is not good

[0006] 3. The number of detected vehicles is limited, and only one vehicle in front and one behind the vehicle can be detected at most

[0007] 4. The price is high, not suitable for a large number of vehicles and ordinary vehicles
