Smart street lamps are based on road lighting poles, integrating public security, traffic signals, communications, and traffic signs to realize the integration of multiple poles, reduce road poles, and release public space resources. At the same time, as an important carrier of smart city construction, smart street lamp will play a greater role of "complex" as a port of the Internet of Things. As the most densely distributed and uniform information infrastructure in the city, lamp posts are considered to be the carrier with better outdoor coverage of 5G base stations. Under the promotion of the construction of smart cities and 5G base stations, the single lighting function will gradually become a new type of public infrastructure.

    In the intelligent street lamp control system, Three Link uses ten trillion core switches as the backbone network and star networking link with multiple aggregation switches. The aggregation layer and access layer switches of each link form redundant self-healing loop network communication. Each access layer switch implements vlan isolation for the intelligent light control system, security monitoring system, LED broadcast system, emergency call system, charging pile system, WIFI hotspot system, and environmental monitoring system to realize non-interference of data in each system.
