Abstract

The invention discloses a vehicle positioning and anti-collision pre-warning system based on ZigBee and GPS (global positioning system). The vehicle positioning and anti-collision pre-warning system is characterized by comprising an information acquisition and communication unit, a main controller unit and an information display and audible and visual alarm unit. The information acquisition and communication unit acquires vehicle information of a vehicle and a wireless communication signal including vehicle information of vehicles in front of the vehicle through a GPS module, an electronic compass module and a ZigBee communication module and transmits a wireless communication signal including vehicle information of the vehicle to vehicles behind. The main controller unit calculates distance between the vehicle and vehicles in front by utilizing the vehicle information and strength of the wireless communication signal, and judges danger grade by utilizing vehicle speed, vehicle moving direction information and the distance. The information display and audible and visual alarm unit displays and alarms the danger grade. The vehicle positioning and anti-collision pre-warning system is used for acquiring adjacent vehicle distance and vehicle speed information, and accordingly a driver can be warned in advance to keep safe driving distance.

Description

technical field [0001] The invention relates to the specific application of wireless sensor network technology in road vehicle driving, in particular to a ZigBee and GPS-based vehicle positioning and anti-collision early warning system. Background technique [0002] In the prior art, vehicle positioning basically adopts GPS (Global Positioning System) technology to obtain longitude and latitude position information of the vehicle itself. However, when using GPS positioning, at least four messages sent by GPS navigation satellites must be received at the same time to calculate the specific position of the vehicle. If the vehicle is in a complex terrain such as a mountainous area or a tunnel, the GPS cannot receive signals from four satellites at the same time, so positioning cannot be achieved; In addition, the current GPS technology can only realize the positioning of the vehicle itself, and cannot know the distance information between the vehicle and the adjacent vehicle in...
