Intelligent street lamp lighting system

Abstract

The invention discloses an intelligent street lamp lighting system, which is characterized in that a CPU control module is connected with a street lamp through a PWM dimming module and used for controlling the PWM dimming module to output a PWM signal to the street lamp so as to enable the street lamp to be turned on with preset brightness; a mobile control terminal is connected with the CPU control module through a bluetooth communication module and used for periodically outputting a timing signal to the CPU control module; the CPU control module controls the street lamp to be turned on within a first preset time in response to the timing signal; an infrared sensing module is connected with the CPU module and used for outputting an infrared sensing signal to the CPU control module when detecting a pedestrian or vehicle; the CPU control module controls the street lamp to be turned on within a second preset time in response to the infrared sensing signal, wherein the length of the second preset time is less than that the length of the first preset time; a light sensing module is connected with the CPU control module and used for outputting a light sensing signal to the CPU control module when the ambient light is detected to not reach a preset value; and the CPU control module controls the street lamp to be turned on in response to the light sensing signal.

Description

technical field [0001] The invention relates to a street lamp system, more specifically to an intelligent street lamp lighting system. Background technique [0002] In 1843, the first kerosene street lamp appeared on the streets of Shanghai, China. Since then, street lamps have played an important role in road lighting. The development of street lamp technology also marks the advanced level of a city. Street lamp control was initially installed on each utility pole with a knife switch, which was turned on and off by workers every day. Later, the time controller switch was specially designed for street lamps. People are constantly looking for effective solutions. , energy-saving and convenient urban lighting management solutions. The most commonly used time controller schemes have the following problems: [0003] 1) The street lights cannot automatically adjust the switch light time according to seasonal changes, and workers need to turn on and manually set the switch light...

AI Technical Summary

Problems solved by technology

[0003] 1) Street lamps cannot automatically adjust the switch light time according to seasonal changes. Workers need to turn on and manually set the switch light time one by one, which is time-consuming and laborious

[0004] 2) Street lights cannot make judgments on vehicles and pedestrians. Even if there is no one on the street in the middle of the night, the street lights always maintain maximum brightness, which greatly wastes urban power

[0005] 3) Street lights cannot cope with sudden weather changes. For example, in the rainy weather during the day, the visual environment is poor, but the street lights remain off before the time to turn on the lights, which affects traffic safety hazards
