This year is a key year for 5g infrastructure construction. As the first batch of 5g pilot cities in China, Shenzhen is expected to build 45000 5g base stations by the end of this month and realize the coverage of 5g network in the whole city. The acceleration of 5g network construction has also brought large-scale growth to the application of multi-functional smart light poles.
5g construction promotes smart pole to enter the “fast lane”
The reporter saw a whole row of neat street lamps along Qianwan road in Shenzhen. This street lamp not only has the function of lighting, but also adds more than ten functions such as Wi Fi, 5g and one button alarm. This is the so-called smart pole. The establishment of smart pole has greatly optimized the smart transportation of a city.
It is understood that the main role of smart pole for urban construction is to promote “multi pole integration and multi-purpose”, change the past phenomenon of “multi pole forest” such as street lamps, video surveillance, traffic signals and operator base stations, and avoid problems such as repeated construction, repeated investment and system non sharing. Smart city is inseparable from smart pole. The collection of various data such as people and vehicle flow statistics, vehicle road coordination and environmental monitoring all need to rely on the basic platform built by smart pole to provide big data sharing services for smart city and promote the interconnection of all things.
According to insiders, this year, as the first year of 5g application, the construction of smart rods in various places is far more than in the past. In Shenzhen, in addition to the urban central road, as the first Shenzhen Meiguan Expressway in China to start the municipal transformation, it fully introduces the intelligent transportation design, takes the intelligent pole as the hardware carrier, integrates multiple poles, mounts 5g base station, HD video monitor and other intelligent road testing equipment, and realizes the intelligent construction and management of road equipment and facilities.
As the first batch of 5g pilot cities in China, the application of smart rods is accelerating. According to the relevant data of Shenzhen Bureau of industry and information technology, it is clear that 4526 multi-functional smart rods will be built in Shenzhen this year and 24000 will be built by 2022. According to the prediction of the International Smart City Research Institute, the market space of smart light poles driven by the construction of 5g base stations will reach 117.6 billion yuan in 2020.
Smart rod hides multiple functions, and cloud data support is indispensable
As the carrier of 5g construction, a complete set of smart rod system includes front-end smart rod, middle-end network transmission and back-end data platform. In the application scenario, with the completion of 5g network, rapid response and linkage will be formed between the three ports. What convenience will this bring to public life? At the same time, in the process of data transmission, how to ensure data security?
In a company engaged in the research and development of smart rods in Shenzhen, the staff told reporters that in addition to the visible functions such as 5g base station, road monitoring and one click alarm, smart rods also hide some invisible functions in the urban underground pipe network and green belt soil.
Yao Zhuohong, software development engineer of Shenzhen Haineng Communication Co., Ltd.: when the well cover is washed away or the well cover fails in the city, our platform can timely receive the failure status of the well cover, see the alarm on the platform, and send the work order to the corresponding personnel for treatment according to the alarm. The intelligent sprinkler system mainly monitors the soil humidity. 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 the work order to the watering company for watering.
For individuals, a large number of applications of smart poles will bring a better convenient experience for everyone’s daily travel in the future.
The front-end application can be controlled uniformly through the background. At the same time, the front-end data can be quickly uploaded to the cloud through the network, and make a rapid response at the application end after big data analysis, processing and sharing in the cloud. It can be said that big data is the nerve center for building a smart city in the future, and smart security, face recognition, driverless and other applications will all rely on big data in the future.
Su Kuifeng, general manager of Tencent autopilot: 5g has high bandwidth and low delay. It can transmit the dynamic information data on the road to the cloud in real time. It can greatly improve the transportation efficiency of the whole city. Take Beijing and Shenzhen for example. In the same traffic flow time, it may be able to carry 2 million vehicles in the past, and it may be able to carry 3 million or even higher vehicles in the future.
If 5g is the era of information interaction, then the big data center is the intersection of various information. According to the Research Report on the development of China’s IDC industry from 2019 to 2020, the compound growth rate of China’s big data center business market will be 27.8% from 2020 to 2022, and the scale of big data center will reach 320 billion yuan in 2022, with great development prospects.
Driverless driving is inseparable from “vehicle road coordination”, which can be popularized on a large scale in a few years
If the smart pole provides a powerful network and big data provides an intelligent cloud, it will form a smart road when applied to urban transportation. If we add cars with automatic driving function, we will jointly build the main field of future intelligent transportation development: vehicle road coordination.
Under the 5g network with high bandwidth and low delay, driverless vehicles can control the direction and avoid obstacles according to navigation. Whether they avoid obstacles or change lanes in advance, the whole process will not make passengers feel uncomfortable; When driving to the intersection, the vehicle can also make plans for deceleration or normal crossing in advance according to the traffic light progress.
According to insiders, vehicle road coordination is simply understood as the data interaction between “vehicle end” and “roadside”. The lidar installed on both sides of the road can more comprehensively and accurately capture traffic information at different distances and angles, and transmit these traffic information to the vehicle end in real time through 5g network, so as to play the role of traffic early warning and prevent traffic accidents.
In the interview, the reporter learned that at present, one roadside equipment needs to be deployed from 500m to 800m to realize network coverage and data acquisition, that is, it will take time to realize the hardware requirements of vehicle road coordination. In order to speed up the construction of roadside equipment such as smart poles, the Ministry of transport recently issued the notice on doing a good job in promoting consumption, capacity expansion and quality improvement, pointing out that it is necessary to promote the construction of new transportation infrastructure, improve the intelligent and digital level of transportation infrastructure, and promote the application of automatic driving and vehicle road coordination technology.
