Internet of Vehicles road early warning method and Internet of Vehicles road early warning system based on Beidou

Abstract

The invention discloses an Internet of Vehicles road early warning method and an Internet of Vehicles road early warning system based on Beidou. The Internet of Vehicles road early warning method comprises steps that fixed point position data and driving position data are acquired, and are returned to a server; a vehicle driving direction, a vehicle driving speed, and a vehicle position change are determined; an abnormal position is compared with the fixed point position. The Internet of Vehicles road early warning system comprises an on-board Beidou positioning module, an on-board GPRS module, an on-board control module, a direction determining module of a server end, an on-board Beidou short message transmission module, the speed determining module of the server end, an on-board early warning information Beidou transmission module, an on-board early warning information Beidou receiving module, an on-board early warning information GPRS transmission module, an on-board early warning information GPRS receiving module, an abnormal position determining module, a comparison module, a first marking module, and a second marking module. The Internet of Vehicles road early warning method and the Internet of Vehicles road early warning system have advantages of rapid response, safety, high efficiency, strong cooperation early warning capability, and low early warning costs on aspects of driving state monitoring, driving safety guarantee, and traffic accident prevention.

Description

technical field

[0001] The invention relates to the field of intelligent transportation, in particular to a Beidou-based vehicle network road early warning method and system. Background technique

[0002] The Beidou satellite system is a global satellite navigation system independently developed by my country with a high degree of independent intellectual property rights. It is also known as the world's four major satellite navigation systems together with the US GPS, Russia's GLONASS, and Europe's Galileo. my country's Beidou satellite navigation system currently has 35 satellites, providing information services such as high-precision positioning, timing, and short-message communication in a wide range of my country and surrounding areas. With its powerful spatial information infrastructure, it has developed a wide coverage Beidou industry. In recent years, with the vigorous development of communication technology and Internet of Things technology, more and more people pay ...
