Abstract

The invention provides a method for monitoring the running state of a vehicle, a roadside beacon and an intelligent traffic system. The method comprises the following steps of: receiving vehicle position information transmitted by a vehicle by a roadside beacon, wherein the vehicle position information comprises the distance of the vehicle relative to the roadside beacon and the direction of a vehicle head of the vehicle; and determining the running state of the vehicle according to the distance of the vehicle relative to the roadside beacon, the direction of the vehicle head of the vehicle and the preset geographical position information of a site in which the roadside beacon is arranged, wherein the direction of the vehicle head of the vehicle is obtained according to a signal transmitted by the roadside beacon, which is received by an intelligent plane antenna array fixedly installed on a vehicular terminal. According to the technical scheme provided by the invention, the position information of the vehicle can be obtained in real time by the vehicular terminal, and the position information can also be transmitted to the roadside beacon in real time or periodically, so that the running state of the vehicle can be accurately obtained in time by the roadside beacon so as to realize the real-time monitoring of the vehicle.

Description

technical field [0001] The invention relates to intelligent traffic technology, in particular to a vehicle running state monitoring method, a roadside beacon and an intelligent traffic monitoring system. Background technique [0002] With the advancement and development of transportation technology, intelligent transportation has become an important development direction of transportation technology. Among them, real-time monitoring of vehicles is the key to realizing intelligent transportation. key. [0003] At present, the positioning of vehicles is usually achieved by using the Global Positioning System (Global Positioning System, GPS), and the geographic location information of the vehicle can be obtained in real time through the GPS positioning system; and other defects, it cannot be widely used in the monitoring communication of vehicles. Therefore, the communication between vehicles and the supervision network is mainly realized by personal mobile communication syste...
