Problems solved by technology

The defect of the existing technology is that the inspection cycle is fixed. When there is a traffic jam in a certain road section, the operation center must complete a cycle to update the new data of the road section. In the case of long roads and a large number of networked communication devices , there is a problem that the data update of the accident road section is slow, and the front-end feedback is not timely

Embodiment Construction

[0028] The vehicle of this embodiment is a self-driving vehicle, which is provided with a conventional laser sensor (Ibeo), a visual sensor (binocular vision camera), a position sensor (GPS), front and rear radars, and a main control computer (Nuvo-5095GC industrial computer) The composed automatic driving system can implement conventional sensor detection and driving control required for automatic driving.

[0029] In this embodiment, the roadside unit refers to a plurality of networked communication devices arranged at equal intervals on the side of the road. The communication technology communicates with each other, and then controls each roadside unit to perform periodic broadcast network paging requests in a short cycle within its communication range, and the vehicle establishes a communication link after receiving the request, so as to realize the communication between the roadside unit and its communication range Each vehicle is networked to ensure that each roadside un...

Abstract

The invention relates to a roadside unit inspection method and device, and a computer readable storage medium, and the method comprises the steps: S1, sequentially labeling each roadside unit, so as to form a queue; S2, in each period A, enabling each road side unit in the request queue to sequentially upload the collected average vehicle speed of the vehicles in the network; S3, drawing a vehiclespeed change curve of the road based on the average vehicle speed; and S4, searching for valley points in the vehicle speed change curve, if the average vehicle speed corresponding to the valley points is smaller than the set early warning vehicle speed, controlling the road side units corresponding to the valley points to additionally and independently upload the average vehicle speed in the network of the road side units according to a period B, wherein the period B is smaller than the period A. According to the invention, targeted data can be quickly updated, the daily inspection process is not influenced, the problem node at the front end can be timely fed back under the condition that the number of the roadside units is large, and the data updating timeliness of the problem node is improved.

Description

technical field [0001] The invention relates to the field of road monitoring, in particular to a roadside unit inspection method, equipment, and a computer-readable storage medium. Background technique [0002] On the side of the existing autonomous driving road, multiple network communication devices arranged at equal intervals need to be installed, and the operation center periodically requests each network communication device to upload the information of its networked vehicles in order to realize daily inspection work. The defect of the existing technology is that the inspection cycle is fixed. When there is a traffic jam in a certain road section, the operation center must complete a cycle to update the new data of the road section. In the case of long roads and a large number of networked communication devices , there is a problem that the data update of the accident road section is slow, and the front-end feedback is not timely. Contents of the invention [0003] T...
