A v2x-based roadside equipment system and its information distribution method

Abstract

The present invention claims protection of a V2X-based roadside equipment system and information distribution method, which mainly includes: a communication network management module, a message agent module, an information security component module, a log management component module, and a message bus interface module. The RSU message agent module is responsible for the analysis, priority scheduling and distribution of messages sent by the application layer through the message bus interface to the message bus. The RSU communication network management module is responsible for shielding the protocol differences between the platform and the communication equipment attached to the RSU, and providing a unified communication call interface for the middleware message agent. The present invention manages multi-source information from heterogeneous networks such as road sensors, vehicles, cloud platforms, and differential positioning base stations in a unified manner for V2X RSU, provides a unified communication call interface for upper-layer applications, and improves the efficiency and functional scalability of application development; The messages are scheduled based on the priority strategy to ensure that the messages with higher information density are sent first.

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
