Since the country proposed in December 2018 to 5G artificial intelligence-led construction of new infrastructure, the design and construction of smart cities has entered a new stage, and the wisdom multifunctional light pole is an important carrier of new infrastructure and smart city perception and release equipment, and it is clear that the next five years to accelerate the construction of a strong manufacturing country, a strong quality country, a strong aerospace country, a strong transportation country, a strong network country and digital China. How to make the wisdom multi-functional pole quality strong country, the perfect realization of carrying function, to achieve reasonable structure, neat and suitable appearance, to meet the subsequent arbitrary expansion of loading, is the lighting industry worthy of deep consideration.

         I. Wisdom multi-functional light pole external hanging points and power supply mode

        (1) The wisdom multi-functional light pole should meet 9-15 external hanging points, conventional external equipment: lighting source, wisdom traffic equipment, LED display, broadcasting, environmental sensors, water sensor, camera, emergency call, AP, 5G micro station, external integrated equipment box; according to the scene demand can also carry electric car charging pile (AC), cell phone charging port, solar energy equipment, drone apron Various types of equipment crossbars or brackets.

        (2) Smart multi-functional light pole external nodes should be designed as: fixed and rail type two types

Fixed type mainly meets the installation of traffic signs, signal light crossbars, LED medium and large intelligence panels, AP, 4G/5G micro-stations, wisdom crossbar nodes that can be pre-locked in position, etc.;

        Guide rails are divided into vertical guide rails and horizontal guide rails: vertical guide rails to meet the needs of the installation height and connection size of various types of external equipment in Article (1), as well as the mounting length of wisdom traffic equipment crossbars within 6m; horizontal guide rails should meet the installation needs of various types of wisdom traffic equipment connection size.

        (3) The common low-power devices of intelligent multifunctional light poles include: broadcasting, sensors, cameras, emergency calls, AP, cell phone charging ports, etc. The single power of these devices is within 100W.

        (4) The common medium power devices of intelligent multi-functional light poles include: LED lighting light source, the power is generally between 50W-500W (decided according to the actual situation of the road), and the power of LED information display is usually different according to the size of the display, working brightness and other conditions, but generally in 350W-1kW/m2.

        (5) The common high power devices of smart multifunctional light poles include: pole-mounted 5G base station, AC charging pile (electric vehicle charging), the single power of pole-mounted micro base station usually does not exceed 800W, and the AC charging pile for electric vehicle charging generally has a power of 7000W.

       (6) Smart multifunctional light poles are commonly supplied with single-phase or three-phase AC power; DC power supply can be used for special project needs. The power distribution system is powered by underground cable lines, and a combination of chain-type and radiation-type power supply is used: chain-type power supply is used from the external integrated power cabinet to the external integrated equipment box and pole equipment box, and radiation-type power supply is used from the external integrated power cabinet to the terminal power equipment; road lighting and intelligent traffic control system facilities are powered by the integrated power cabinet.
