With the rapid development of the intelligent networked vehicle industry, vehicle-road-cloud integration has become an important direction to promote the intelligence and efficiency of the transportation system. At the beginning of July 2024, the Ministry of Industry and Information Technology and other five departments issued the "Notice on Announcing the List of Pilot Cities for the Application of "Vehicle-Road-Cloud Integration" for Intelligent Network Vehicles", which identified 20 cities (consortiums) including Beijing, Shanghai, Shenzhen, Guangzhou, Wuhan, Changsha, Chongqing, Nanjing, Suzhou, Chengdu, and Hangzhou-Tongxiang-Deqing Consortium as the first batch of pilot cities for the application of "vehicle-road-cloud integration", which marks that "vehicle-road-cloud integration" has entered a new stage of large-scale development.

Shanghai Boying Communication Technology Co., Ltd., as a leading enterprise in industrial product development, production and service, its MRD meridian TSN clock sensitive network switch, with its "deterministic transmission", "low latency" and "high reliability" to meet the needs of the "vehicle-road-cloud integration" project, has played an important role in the vehicle-road-cloud project in Fengxian District, Shanghai, and provided a strong guarantee for the successful implementation of the project.

 

 

What is vehicle-road-cloud integration?

The so-called "vehicle-road-cloud integration" refers to the use of a new generation of information and communication technologies. The physical space and information space of people, vehicles, roads, and clouds are integrated to realize the safe, energy-saving, comfortable, and efficient operation of the intelligent networked vehicle transportation system.

To put it simply, it is to let the "hurried car" run the "smart road" under the coordination of the cloud

Challenges and needs of vehicle-road integration

(1) Bandwidth and stable transmission requirements

· Due to the long lines, scattered locations, and the need to access a large number of surveillance video terminals, the throughput increases dramatically and the demand for bandwidth resources is huge.

· Packet loss, delay and other problems are prone to occur during transmission, which affects the stability of data transmission

· Some scenarios require high real-time performance, and require a large number of bandwidth networks to ensure the rapid transmission and sharing of data to maintain the stability of transmission.

(2) Accurate perception is required for full-scene coverage

· The large-scale application of edge vehicle-road collaboration focuses on the optimization of roadside transportation facilities.

· It is necessary to use high-density and high-precision front-end sensing software and hardware to implement intelligent coverage of all scenarios such as road sections, tunnels, and bridges.

· The perception system needs to maintain stable perception performance in low visibility conditions such as rain, fog, and night, and detect abnormal information in time and respond to it.

· Achieve quasi-all-weather traffic, so the accurate perception ability of the perception system is crucial.

(3) The need for centralized management of multiple devices in harsh outdoor environments

· The geological conditions along the highway are complex, the transmission distance is long, the on-site environment is diverse, and it is susceptible to severe weather and environmental impacts such as thunderstorms, dust, high temperature and humidity.

· There is an urgent need for centralized management of multiple equipment to ensure the stable operation and effective maintenance of equipment.

Shanghai Boying MRD radial industrial switch with its "deterministic transmission", "low latency" and "high reliability" is widely used in vehicle-road coordination roadside support environment construction, data center expansion and other links, the launch of TSN clock sensitive network switch, can achieve line failure, switch failure after millisecond switching, to ensure the reliable, efficient, sustainable and stable transmission of video data, to ensure that the system can be quickly restored in the event of a failure, so as to ensure the smooth and safe traffic.

The application of Shanghai Boyingtong MRD radial industrial switch in the vehicle-road-cloud integration project in Fengxian District, Shanghai not only demonstrates the excellent performance and wide application fields of MRD radial industrial switch, but also injects new vitality and guarantee into the development of vehicle-road-cloud integration. In the future, we will continue to devote ourselves to the research and development of more advanced and reliable communication equipment, and make greater contributions to the intelligence and efficiency of the transportation system.
