The illumination intensity detection module detects ambient light; the partial discharge detection module detects the partial discharge condition of the street lamp; the main control module controls the modules to work; the conversion control module selects a control path; according to the intelligent street lamp power supply system based on the photoelectric sensor, detected illuminance data is compared with an illuminance threshold value, the main control module makes a judgment and intelligently controls work of the constant-current drive and the constant-voltage drive, then the working mode of a street lamp is controlled, and short circuit or overload of a circuit is effectively prevented through constant-current and constant-voltage switching; partial discharge detection is realized by adopting a photoelectric detection mode.

Description

technical field [0001] The invention relates to the technical field of street lamp power supply control, in particular to an intelligent street lamp power supply system based on a photoelectric sensor. Background technique [0002] With the advancement of social science and technology, LEDs have been widely used as a new type of light source for smart street lights. Coupled with the continuous optimization of photoelectric sensing technology, the ingenious combination of photoelectric sensing technology and LED street lights can realize the power supply control of smart street lights. However, the existing street lamp power supply system can be driven by two driving modules of constant current and constant voltage. Since constant voltage driving will lead to inconsistent brightness of high-load street lamps, the lighting effect of street lamps will be poor, so most street lamps are driven by constant current. Drive high-load street lamps, but the load can not be open-circuit...

[0002] With the advancement of social science and technology, LED has been widely used as a new light source for smart street lights. Coupled with the continuous optimization of photoelectric sensing technology, the ingenious combination of photoelectric sensing technology and LED street lights can realize the power supply control of smart street lights. , but the existing street lamp power supply system can be driven by two kinds of drive modules, constant current and constant voltage. Since constant voltage drive will lead to inconsistent brightness of high-load street lamps and poor lighting effect of street lamps, most street lamps use constant current drive. Drive high-load street lamps, but the load open circuit cannot occur. Therefore, in practical applications, it is necessary to drive the street lamps with constant current and constant voltage reasonably and intelligently to achieve reasonable power supply control of street lamps. In order to ensure the intelligent control of street lamps, adopt Reasonable planning of photoelectric sensors can play the role of protection, regulation and intelligent power supply of street lights
