The city has a large number of street lamps, which are the most densely distributed urban infrastructure, facilitating the collection and distribution of information. The future of smart street lamps is an important source of information collection for the Internet of Things. Urban smart street lamps are an important part and import of smart cities, which can promote the implementation of smart municipal and smart cities in urban lighting business, and improve the city and municipal service capacity.

1. Zhizhi Street Lamp is the best import and service port of Zhizhi City

Intelligence street lamp is an important part of intelligence city. It uses city sensors, power line carrier/ZIGBEE communication skills and wireless GPRS/CDMA communication skills to connect the street lamps in the city to form the Internet of Things. It completes the long-distance centralized control and handling of street lamps. It has the functions of automatically adjusting the brightness, long-distance lighting control, automatic fault alarm, anti-theft of lamps and cables, long-distance meter reading, etc. according to the traffic flow, time, weather conditions and other conditions.

Smart street lamps can effectively control energy consumption, significantly save power resources, improve public lighting management level, reduce protection and management costs, and use information processing skills such as computing to process and analyze massive perceptual information, and provide intelligent response and intelligent decision support for various needs including people's livelihood, environment, public safety, so that urban road lighting can reach the "smart" status.

1. Telemetry of electrical parameters such as street lamp current and voltage, remote control of street lamp switching, remote viewing of on-site operation of important road sections, etc.

2. Monitor LED street lamp chip pad temperature or lamp housing temperature and fault diagnosis.

3. Daylight sensing or driver vehicle sensing dimming, as well as time control and even RTC dimming during energy-saving operation.

4. According to the monitoring data of lamps and lanterns, the location and cause of abnormal street lamps were timely grasped, and the maintenance was intended without going to the whole city for patrol inspection, which accelerated the protection speed and reduced the protection cost.

5. The lighting specification level on the same route becomes a variable value with the change of time and traffic flow. For example, the brightness of some newly developed roads can be lower at the initial stage of traffic, and they will be fully lit after a period of time or after the monitored traffic flow reaches a certain threshold.

6. In some areas where people and vehicles are sparse, it can be time controlled to be half bright in the second half of the night. However, when people and vehicles arrive at the front after expiration, they will be fully bright at a certain interval, and the rear will recover the original brightness in a few seconds.

2. What are the functions of smart street lamps? From the perspective of lighting, what functions should intelligent street lamps cover?
