Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0015] As shown in Figure 1 , an intelligent control system of a street lamp comprises: a data monitoring module 1, a centralized controller 2, a central control module 3, a light module 4, an alarm module 5, an energy monitoring module 6, and an energy monitoring module 6.
[0016] The data monitoring module 1 is used to monitor and collect environmental data in real time according to various sensors, or adjust the sensor parameters according to the modification instruction.

Sound noise monitor 11 for real-time monitoring and recording noise levels, by analyzing monitoring data, the main source of noise can be determined, so as to take targeted control and emission reduction measures, and can help identify different noise types such as traffic, construction, and formulate corresponding control measures to optimize urban sound environment. Through integration with sound source positioning technology, the sound noise monitor can quickly locate the source of disturbing noise and improve noise law enforcement efficiency; Intelligent camera 12 for monitoring people, vehicles and environmental conditions, conducting security monitoring and collecting traffic data; Traffic flow counter 13 for monitoring and identifying traffic density; when the traffic flow is low (such as at night or off-peak hours), the system automatically reduces the lighting brightness to a low safety standard; when the traffic flow increases (such as peak hours or traffic accidents causing congestion), the brightness will increase accordingly to ensure clear vision for drivers; Motion displacement sensor 14 for monitoring whether a vehicle or pedestrian passes through and automatically controlling the on-off of the street light according to the detection result. When the sensor detects a displacement change, it will send a signal to the central control module 3, which will then automatically turn on the street light according to the preset program.

Abnormal changes in temperature and humidity data can provide auxiliary basis for meteorological departments to predict disastrous weather such as heavy rain and high temperature, and make preparations for disaster prevention and mitigation in advance; Illumination sensor 18 for monitoring environmental illumination intensity data to automatically adjust the brightness or on-off state of the street light according to the environmental illumination intensity, avoiding excessive lighting to save energy, and automatically turning on or adjusting the brightness of the street light when the illumination is insufficient to ensure sufficient lighting on the road and improve traffic safety; Display screen 19 for displaying real-time collected temperature and humidity, wind speed, PM2.5, and weather conditions to provide convenience for urban environmental governance and residents' life and travel.
