Road traffic information collection method, device and storage medium based on roadside unit

Abstract

The present invention relates to a road traffic information collection method, device, and storage medium based on roadside units, including: Step S1. Arranging a plurality of roadside units for network communication at equal intervals along the side of the road, and controlling each roadside unit Respectively form a network with each vehicle within its communication range; Step S2. For each roadside unit, control it to access each vehicle in the network in sequence, and control the roadside unit to access the current access vehicle at each visit. After sending the driving data upload request, directly jump to access the next vehicle; step S3. Configure a message queue for each roadside unit, and control the vehicle to directly input its driving data to the corresponding roadside in the form of a data packet after receiving the request The message queue of the unit; Step S4. Control each roadside unit to periodically collect the data in the message queue and upload it to the operation center. The invention can improve the data throughput of the roadside unit, ensure that vehicles can upload data without interfering with each other, and avoid information collection omissions.

Description

technical field [0001] The invention relates to the field of automatic driving, in particular to a roadside unit-based road traffic information collection method, device, and storage medium. Background technique [0002] On the side of the autonomous driving road, there are multiple networked communication devices arranged at equal intervals, which are used to realize the relay communication between the operation center and road vehicles. During communication, the networked communication devices and road vehicles generally use wheel Inquiry method, that is, after the network communication equipment obtains the driving data of one of the vehicles with which it is connected to the network, it then obtains the driving data of the next vehicle until the traversal of each vehicle in the network is completed. There is no problem when there are few vehicles and the speed is slow, but when there is a lot of traffic and the speed is fast, it is easy for non-polling vehicles to drive ...

Problems solved by technology

[0002] On the side of the autonomous driving road, there are multiple networked communication devices arranged at equal intervals, which are used to realize the relay communication between the operation center and road vehicles. During communication, the networked communication devices and road vehicles generally use wheel Inquiry method, that is, after the network communication equipment obtains the driving data of one of the vehicles with which it is connected to the network, it then obtains the driving data of the next vehicle until the traversal of each vehicle in the network is completed. There is no problem when there are few vehicles and the speed is slow, but when there is a lot of traffic and the speed is fast, it is easy for the non-polling vehicle to drive out of the communication range of the network communication device, resulting in the omission of information collection.
