Intelligent control device and control method for street light switch

Abstract

An intelligent control device for a street lamp switch, comprising a street lamp and multiple groups of LED lighting lamp groups arranged in the street lamp light box, each group of LED lighting lamp groups is connected to a single-chip microcomputer through its own relay; it also includes a sensor for sensing passing pedestrians and vehicles Radar, the radar is connected with the microcontroller. A control method uses a single-chip microcomputer to generate and count pulse signals from induction signals generated by radar, and uses the count of pulse signals per unit time and the multiple of a set threshold as a comparison value to control the lighting quantity of LED lighting groups. On the one hand, the present invention can correspondingly reduce the lighting groups of LED lighting groups and reduce power consumption, and on the other hand, make each LED lighting group be turned on. The alternate lighting of each LED lighting group reduces the probability of the LED lighting group being burned due to heat, and also reduces the average lighting time of each LED lighting group, prolonging the service life of the entire LED lighting group. The invention solves the contradiction between street lamp lighting service and energy consumption, and has great significance.

Description

technical field [0001] The invention relates to the technical field of intelligent control of street lamp switches, in particular to an intelligent control device for street lamp switches and a control method thereof. Background technique [0002] Street lamps are an important part of urban lighting. Traditional high-pressure sodium lamps cause energy waste due to their low luminous efficiency, while high-power LED street lamps use low-voltage DC power supply and are high-efficiency white light diodes composed of GaN-based power blue LEDs and yellow phosphors. It has unique advantages such as high efficiency, safety, energy saving, long switch life, and fast response, and can be widely used in urban road lighting. At present, LED lighting technology is becoming more and more mature, and LED street lamps, especially high-power LED street lamps, are impacting the traditional street lamp market at a rapid speed. [0003] Although LED street lights have greatly improved in term...

AI Technical Summary

Problems solved by technology

In addition, most of the existing LED street lights are illuminated by multiple LED lighting groups in parallel, and the number and rotation sequence of the LED lighting groups cannot be intelligently exchanged according to pedestrians and vehicles, which greatly shortens the service life of the LED lighting groups.
