This year is a key year for 5G infrastructure construction, and Shenzhen, as the country's first batch of 5G pilot cities, is expected to build 45,000 5G base stations by the end of this month, and achieve 5G network coverage throughout the city. The acceleration of 5G network construction has also brought large-scale growth in the application of multifunctional smart light poles.
5G construction has spawned smart poles into the "fast lane"
The reporter saw a neat row of street lights on Qianwan Road in Shenzhen. This street light not only has the function of lighting, but also added more than ten functions such as Wi-Fi, 5G and one-key alarm. This is what it is said. Smart poles, the establishment of smart poles has greatly optimized the smart transportation of a city.
It is understood that the main role of smart poles in urban construction is to promote "multiple poles in one, one pole for multiple purposes", changing the phenomenon of "multiple poles" such as street lights, video surveillance, traffic signals, and operator base stations, and avoiding repeated construction, Problems such as repeated investment and system not sharing. Smart cities are inseparable from smart poles. The collection of various data such as traffic flow statistics, vehicle-route coordination, and environmental monitoring requires a basic platform built by smart poles to provide big data sharing services for smart cities and promote the interconnection of everything.
According to industry insiders, this year, as the first year of 5G applications, the construction of smart poles in various places has far exceeded the past. In Shenzhen, in addition to the city’s central roads, Shenzhen Meiguan Expressway, which is the first domestic urbanization transformation, has fully introduced smart transportation design, using smart poles as the hardware carrier, multi-pole integration, and 5G base stations and HD Intelligent road test equipment such as video monitors realize the intelligent construction and management of road equipment and facilities.
As the first batch of 5G pilot cities in the country, the application of smart poles is accelerating. According to relevant data from the Shenzhen Bureau of Industry and Information Technology, it is clear that Shenzhen will build 4,526 multifunctional smart poles this year, and 24,000 will be built by 2022. root. According to the International Smart City Research Institute, in 2020, the market for smart light poles driven by the construction of 5G base stations will reach 117.6 billion yuan.
Smart bar hides multiple functions and cloud data support is indispensable
As the carrier of 5G construction, a complete set of smart pole system, including front-end smart pole, mid-end network transmission, and back-end data platform. In the application scenario, as the 5G network is completed, the three ports will also form a rapid response and linkage. What convenience will this bring to the lives of the public? At the same time, how to ensure data security during data transmission?
In a company engaged in the research and development of smart poles in Shenzhen, the staff told reporters that in addition to the visible functions such as mounting 5G base stations, road monitoring, and one-key alarms, smart poles are also hidden in the urban underground pipe network and the soil of the green belt. Some invisible features.
Yao Zhuohong, Software Development Engineer, Shenzhen Haineng Communication Co., Ltd.: When a flood in the city washes away the manhole cover or the manhole cover fails, our platform can receive the failure status of the manhole cover in time, and the alarm can be seen on the platform. Dispatch work orders according to the alarm to the corresponding personnel for processing. The intelligent sprinkler irrigation system mainly monitors the humidity of the soil. After it is placed in the dry soil, the Internet of Things will collect its humidity data and send it to the platform. The platform will remind the humidity and send a work order to the watering company for watering.
For individuals, the large number of applications of smart poles will bring a better and more convenient experience for everyone's daily travel in the future.
Through the background, the front-end applications can be uniformly controlled, and the front-end data can be quickly uploaded to the cloud through the network, and after the cloud big data is analyzed, processed and shared, the application can react quickly. It can be said that big data is the nerve center for building future smart cities, and applications such as smart security, face recognition, and driverless driving will all rely on big data in the future.
Su Kuifeng, general manager of Tencent Autopilot: 5G has high bandwidth and low latency. It can transmit dynamic information data on the road to the cloud in real time. It can greatly improve the transportation efficiency of the entire city. Taking Beijing and Shenzhen as examples, within the same traffic flow time, it may originally be able to carry 2 million vehicles, but in the future it may be able to carry 3 million or more vehicles.
If 5G is the era of information interaction, then the big data center is the intersection of various information. According to the "China IDC Industry Development Research Report 2019-2020", my country's big data center business market scale compound growth rate will be 27.8% from 2020 to 2022, and the scale of big data center will reach 320 billion yuan in 2022, and the development prospects are huge.
Autonomous driving is inseparable from "vehicle-road synergy" and it can be promoted on a large scale in a few years
If the smart pole provides a powerful network and big data provides a smart cloud, then when applied to urban traffic, it will jointly form a smart road. If you add a car with autonomous driving functions, you will jointly build the main field of future smart transportation development: vehicle-road collaboration.
Under the high-bandwidth and low-latency 5G network, unmanned vehicles can control the direction and avoid obstacles based on navigation. Whether it is avoiding obstacles or changing lanes in advance, the whole process will not make passengers feel uncomfortable; driving to the intersection, the vehicle According to the progress of the traffic lights, it can also make plans for deceleration or normal crossing in advance.
According to industry insiders, a simple understanding of vehicle-road collaboration is the data interaction between the "vehicle end" and the "roadside". Lidar installed on both sides of the road can more comprehensively and accurately capture traffic information at different distances and angles, and transmit this traffic information to the car terminal in real time through the 5G network, thus playing a role in traffic warning and preventing traffic accidents occur.
The reporter learned during the interview that at present, about one roadside device is deployed at 500 meters to 800 meters to achieve network coverage and data collection. That is to say, it will take time to achieve the hardware requirements for vehicle-road coordination. In order to accelerate the construction of roadside equipment such as smart poles, the Ministry of Transport recently issued the "Notice on Doing a Good Job in Transportation to Promote Consumption Expansion and Quality Improvement", which pointed out that the construction of new transportation infrastructure will be promoted, and the level of intelligent and digital transportation infrastructure will be improved. Promote the application of autonomous driving and vehicle-road collaboration technologies.
