IOV (Internet of Vehicles) communication system based on ZigBee

Abstract

The invention discloses an IOV (Internet of Vehicles) communication system based on ZigBee. The system includes a vehicle-mounted terminal subsystem, a traffic flow prediction subsystem, a motion trajectory simulation subsystem, a traffic signal real-time control subsystem, a traffic information release subsystem, a traffic violation monitoring subsystem, a database subsystem, and a cloud computing processing platform. The data collected by ach subsystem is transmitted to a server in the cloud computing processing platform, and each vehicle carries one vehicle-mounted terminal subsystem. The system directly transmits a signal to the vehicle-mounted terminal by short-range wireless communication, so the system has high accuracy, is free from environmental interference, and has good real-time performance. The traffic flow prediction subsystem predicts the future traffic flow. The motion trajectory simulation subsystem simulates the vehicle's motion trajectory in real time. By adding thecommunication module between the roadside devices, the cost of the vehicle terminal is reduced, and the whole process quick interaction is achieved. The system gives full play to the advantages of lowpower and high reliability wireless communication of a ZigBee module in roadside devices.

Description

technical field [0001] The invention relates to the communication field and the transportation field, in particular to a vehicle networking communication system based on ZigBee wireless communication mode. Background technique [0002] One of the core issues that needs to be solved to improve the security of the Internet of Vehicles is to discover the existence of potential safety hazards in the Internet of Vehicles, and to improve the speed and accuracy of communication between vehicles, vehicles and roads, and roads and roads.

AI Technical Summary

Problems solved by technology

[0016] One is that the current vehicle terminal is equipped with a large number of sensors, which will not only increase the cost of the vehicle, but also cause network congestion due to the data transmission of a large number of sensors during the transmission process, which will lead to inaccurate judgments of the vehicle driving safety by the central control platform ;

[0017] Second, as the number of vehicles continues to increase, the increase in the communication density between vehicles and vehicles and between vehicles and roads will increase communication delays, which is not conducive to the accuracy and reliability of Internet of Vehicles communication.
