Vehicle-road cooperation roadside intelligent calculation and communication device and method based on artificial intelligence

Abstract

The invention discloses a vehicle-road cooperation roadside intelligent calculation and communication device and method based on artificial intelligence. The device comprises an MEC intelligent calculation unit of which the input end is connected with roadside sensing equipment, and which is used for receiving, analyzing and calculating various road state information collected by the roadside sensing equipment; an RSU communication unit, wherein the input end of the RSU communication unit is connected with the output end of the MEC intelligent calculation unit, and the output end of the same communicates with a vehicle in real time and is used for receiving results analyzed and calculated by the MEC intelligent calculation unit and transmitting the results to the vehicle; and a system power supply module, which is connected with the MEC intelligent computing unit and the RSU communication unit and is used for supplying power to the MEC intelligent computing unit and the RSU communication unit. By fusing the calculation unit and the communication unit and integrating the calculation and communication functions, circuit connection is adopted, wiring points can be reduced by 90%, and the fault rate can be reduced by 90%; as long as equipment is reliable, communication and calculation are also reliable.

Description

technical field [0001] The invention relates to an artificial intelligence-based roadside intelligent computing and communication device and method for vehicle-road coordination, and belongs to the technical field of vehicle-road coordination. Background technique [0002] With the development of science and technology, automatic driving has gradually entered people's lives and is being accepted by people. In order to ensure the accuracy and safety of automatic driving, roadside sensing devices for real-time collection of road conditions and traffic conditions are generally arranged on the road, and roadside sensors for real-time analysis and calculation of road information are arranged on both sides of the road At the same time, roadside communication units (RSU) for real-time communication with intelligent networked vehicles are arranged on both sides of the road. Among them, the roadside sensing equipment mainly includes cameras, lidar and millimeter-wave radar and other...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the MEC and RSU are configured one-to-one, and the RSU is installed on the horizontal bar of the gantry, and the MEC is installed on the vertical bar of the gantry, there are many wiring points, which increases the complexity of the on-site construction connection, and there are many fault points. Reliability is reduced; at the same time, MEC has its own equipment box. There are many devices in the equipment box, and the components are scattered, and the fault cannot be sensed. When a device in the equipment box fails, the entire equipment will be paralyzed;

[0005] 2. Due to the separation of calculation and communication functions, the workload of compatibility debugging between various devices is large. After the MEC is calculated, it is transmitted to the RSU for communication through wired or wireless methods. There are cases where transmission is interrupted or cannot be sent out, and the system is stable. , The reliability is reduced. When a problem occurs, it is difficult to determine whether it is a calculation problem or a communication problem;

[0006] 3. Since the lightning protection devices in the MEC and RSU cannot be recovered after tripping, the MEC and RSU on the expressway are generally arranged at intervals of 500 meters. Multiple pieces of equipment will be damaged, and it will be difficult to make centralized maintenance the next day, which is time-consuming and labor-intensive;

[0007] 4. There is no power-off protection. When a power failure occurs, the MEC and RSU equipment will be damaged and cannot continue to provide road conditions for vehicles, and the safety factor is low;

[0008] 5. In remote areas and beside expressways, where it is difficult, expensive, and time-intensive to maintain on site, the equipment must have remote management and maintenance capabilities

However, most devices currently do not have remote management capabilities. Even if a few devices have remote management capabilities, there are still high threshold conditions. For example, there must be a network, the device system operating system, and the system CPU must be able to continue to work, so that the remote server can continue to communicate with the device. Perform data docking interaction or send operation commands, and when the system crashes and the CPU hangs in some extreme cases, such as remote device upgrade failures, system CPU hangs due to high-density interruptions, memory leaks, etc., remote maintenance methods are also available. broken
