As a widely distributed, integratable and easily deployable urban infrastructure, street light poles have become the best way to achieve data collection and signal coverage for smart city systems with the development of 5G, IoT, artificial intelligence and other new generation information technologies. From simple lighting streetlights gradually developed into a new urban public infrastructure consisting of poles, integrated boxes and integrated pipes, etc. – smart streetlights, on the basis of achieving basic lighting functions, integrate a variety of equipment and facilities to achieve a pole multi-purpose, in the city to reduce emissions and improve efficiency, information dissemination, security monitoring, new energy vehicle charging and commercial promotion Many segments have been applied.
Reviewing the development of the intelligent street light industry, it is not a straight path.
In 2016, China”s intelligent light poles were officially landed.
2017 – 2018, China”s wisdom light pole technology is becoming increasingly mature, but the actual landing is limited by the development of operation, profit model and other issues.
after 2018, China”s provinces and municipalities have issued policy documents to promote the development of information industry and the construction of intelligent street light projects.
Until 2019, under the impetus of “5G new base construction”, the development of intelligent street lights gradually entered the fast lane.
Recently, the Ministry of Housing and Urban-Rural Development and the Ministry of Industry and Information Technology issued a notice to identify six cities, including Beijing, Shanghai, Changsha, Guangzhou, Wuhan and Wuxi, as the first batch of pilot cities for the collaborative development of smart city infrastructure and smart network-connected vehicles.
Smart cities and smart connected cars are complementary. Smart cities serve as the basis for the development of smart connected cars, while smart connected cars are the entry point for the development of smart cities.
The best carrier for the development of vehicle-road cooperation
Vehicle-road collaboration mainly involves three ports: vehicle side, roadside side and cloud side. Based on 5G and other advanced communication technologies, intelligent sensing and computing devices are deployed at the roadside to realize information sharing between vehicles and roads. At the same time, the deployment of perception equipment at the roadside end will make up for the shortcomings of the vehicle end with perceptual blindness and limited view distance, and improve the safety of autonomous driving.
In addition, through the intelligent collaboration and cooperation between vehicles and roadside unit sensing devices, the goal of improving traffic efficiency and relieving traffic congestion will be achieved. Remote monitoring and traffic scheduling and automatic driving control using the cloud.
The “human-vehicle-road-cloud” collaborative operation, based on the existing vehicle-road collaboration, realizes the autonomous control of all traffic participants in the whole road section, all-weather and all-scene through global control, and provides effective information for single-vehicle decision-making.
The ability of roadside perception, decision analysis and data processing will effectively promote the development of vehicle-road cooperation industry.
Accurate perception is the foundation and key to realize vehicle-road cooperation, build smart highway and develop smart transportation. The smart light pole is one of the best carriers for deploying roadside units in the development of vehicle-city synergy. It mainly consists of traffic navigation data collection, safety prevention data collection, radio frequency identification and other modules, which can sense the operation of different dimensions of traffic, environment, vehicles and crowds in urban roads in real time, assist intelligent vehicle decision-making and realize high-safety automatic driving.
The 5G network signal coverage will also be greatly enhanced by the extensive installation of smart light poles. 5G”s large bandwidth, low latency, and massive connection characteristics also provide network signal guarantee for vehicle-road cooperation and autonomous driving.
The smart light poles are equipped with LIDAR, which captures comprehensive and accurate traffic information of multiple road sections and angles, and transmits it to the car in real time for road condition warning.
In addition, some of the smart light poles are also linked to car charging piles to meet the charging needs of new energy vehicles, which can largely alleviate the painful urban service points of difficult charging and charging location, and promote the rapid development of smart network-connected vehicles.
As the commercialization of 5G accelerates, the smart light pole, with its own “electricity, network, point” and other powerful advantages, can empower the construction of smart cities, digital operations, and promote the development of the smart light pole industry.
