Street lamp variable switch intelligent control device and control method thereof

Abstract

The invention provides a street lamp variable switch intelligent control device. The device comprises a street lamp and a plurality of LED lighting lamp sets arranged in a lamp box of the street lamp,and each LED lighting lamp set is connected with a single-chip microcomputer through a relay of the LED lighting lamp set. The device further comprises a radar used for sensing passing pedestrians and vehicles, and the radar is connected with the single-chip microcomputer. According to the control method, the single-chip microcomputer generates pulse signals from induction signals generated by the radar and counts the pulse signals, and the multiple of the count of the pulse signals in unit time and a set threshold value serves as a comparison value to control the lighting number of the LED lighting lamp sets. On one hand, the number of lightened LED lighting lamp sets can be correspondingly reduced, and electric energy consumption is reduced; and on the other hand, all the LED lighting lamp sets are lightened in turns. All the LED lighting lamp sets are lightened in turn, so that the probability that the LED lighting lamp sets are burnt out due to heating is reduced, meanwhile, the average lightening time of all the LED lighting lamp sets is shortened, and the service life of the whole LED lighting lamp sets is prolonged. The contradiction between street lamp lighting service andenergy consumption is solved, which 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.
