Abstract

A road network monitoring system based on satellite communication positioning and wireless electronic tag technology includes a space section and a road surface section; wherein, the space section is composed of two types of satellites, including a mobile communication satellite and a positioning satellite, the positioning satellite is used for acquiring the position information of a vehicle in a highway, and the mobile communication satellite realizes the communication between a vehicle in the highway and a command center; the road surface section is composed of a ground signal terminal station for supporting the positioning satellite and the mobile communication satellite, a command center and a vehicle positioning communication device, the ground signal terminal station receives and transmits the signals of the two types of satellites, and establishes network communication connection with the command center, and the vehicle positioning communication device is composed of a position indicator, a satellite mobile phone terminal and a wireless electronic tag. By adopting the road network monitoring system and for the vehicles in a highway, the command center can obtain the vehicle information and position information in real-time and can establish speech communication with each vehicle in certain road section, and carry out rescue in time.

Description

technical field [0001] The invention relates to the field of expressway vehicle safety monitoring, in particular to a road network monitoring system based on satellite communication positioning and wireless electronic tag technology. Background technique [0002] At present, the safety monitoring of driving vehicles in the expressway network mainly relies on cameras and speed measuring devices installed on the expressway for image acquisition and speed monitoring; road safety is mainly maintained by the police on the road section. It is partial and hysteresis, and there is no complete guarantee for the vehicle safety of the expressway network. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, to provide a kind of vehicle information, location information for each vehicle on the highway, and to communicate with each vehicle based on satellite Communication positioning and wireless electronic label technolog...
