Vehicle-road coordination method and system based on Beidou high-precision positioning

Abstract

The invention discloses a vehicle-road coordination method based on Beidou high-precision positioning, comprising: a vehicle-mounted collaborative processing device collects vehicle driving environment information, vehicle condition data information, and Beidou positioning data, and sends them to roadside collaborative processing equipment or a service control platform; The roadside collaborative processing device generates road condition information and image positioning data and sends them to the service control platform; sends the roadside positioning data to the service control platform; the service control platform uses Beidou positioning data, image positioning data, and roadside positioning data to perform Comprehensive positioning analysis and processing, generate accurate positioning data feedback and send it to the on-board collaborative processing device. In addition, the invention also discloses a vehicle-road coordination system based on Beidou high-precision positioning. By adopting the vehicle-road coordination system and the vehicle-road coordination method of the present invention, the position of the vehicle can be precisely positioned, the operation and efficiency of the traffic system are greatly improved, and the occurrence of traffic accidents is largely avoided.

Description

technical field [0001] The invention relates to the technical field of Internet of Vehicles, in particular to a vehicle-road coordination method and system based on Beidou high-precision positioning. Background technique [0002] In the existing technology, the Internet of Vehicles uses wireless communication, sensor detection and other technologies to collect information on vehicles, roads, and the environment, and through vehicle-to-vehicle and vehicle-to-road information interaction and sharing, intelligent collaboration and cooperation between vehicles and infrastructure , so as to realize the integrated network of intelligent traffic management control, vehicle intelligent control and intelligent dynamic information service, which is the extension of Internet of Things technology in the field of intelligent transportation system. Based on the intra-vehicle network, the inter-vehicle network and the vehicle-mounted mobile Internet, in accordance with the agreed communica...

Problems solved by technology

However, due to the ground segment errors (such as: ionosphere, troposphere, multipath and relativistic effects) of the satellite signal in the propagation process, and human interference errors - the US SA policy (Selective Availability before 2000, the United States for civil GPS signal interference policy), etc., the positioning accuracy can only reach tens of meters or even hundreds of meters, which cannot meet the requirements of navigation, surveying and mapping and other fields
