V2X-based roadside unit system and information distribution method thereof

Abstract

The invention provides a V2X-based roadside unit system and an information distribution method thereof. The system mainly comprises a communication network management module, a message proxy module, an information security component module, a log management component module, a message bus interface module and the like. An RSU (roadside unit) message proxy module is responsible for parsing, priority scheduling and distribution of messages, sent by an application layer through a message bus interface, to a message bus. The RSU communication network management module is responsible for shieldingprotocol difference of a platform and RSU auxiliary communication equipment, and a unified communication calling interface is provided for middleware message proxy. According to the system and the method in the invention, heterogeneous network multi-source information from a road sensor, a vehicle, a cloud platform, a differential positioning base station and the like is managed through the V2X RSU in a unified way, a unified communication calling interface is provided for an upper-layer application, and the application development efficiency and the function expandability are improved; the messages are scheduled on the basis of a priority policy so as to ensure that the information with relatively high information tightness is preferentially sent.

Description

technical field [0001] The invention belongs to the technical field of V2X Internet of Vehicles and intelligent transportation, and specifically belongs to a V2X communication-based roadside equipment software architecture and an information distribution method thereof. Background technique [0002] With the continuous improvement of residents' income level and consumption level, the number of automobiles in my country is increasing rapidly, and the problem of road traffic is becoming increasingly prominent. V2X Internet of Vehicles technology realizes vehicle-to-vehicle (V2V), vehicle-to-roadside infrastructure (V2I), vehicle-to-pedestrian and other vulnerable traffic participants (V2P) through a new generation of communication technology (DSRC / C-V2X / 5G and other communication technologies) , Vehicle-to-cloud platform (V2N) all-round connection and information interaction. [0003] With the characteristics of efficient wireless resource allocation, high-speed and seamless ...

AI Technical Summary

Problems solved by technology

It does not consider the diversity of messages that RSU needs to process and distribute in complex traffic scenarios, nor does it consider the priority of different messages during message distribution, such as road emergency information sent by the cloud platform and vehicle accident information sent by nearby vehicles, RSU needs to occupy the channel priority forwarding
