Embodiment Construction

[0017] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0018] Such as figure 1 As shown, a fuzzy control system for power saving of LED street lamps according to the present invention mainly includes a multiplier, a converter, a fuzzy controller, LED street lamps and sensors. Among them, the multiplier is connected with the converter to input the light intensity of the LED street lamp. The converter is responsible for converting the input light intensity signal into a digital signal and passing it to the input end of the fuzzy controller. The output port interface of the fuzzy controller will be These digital signals are converted into PWM modulation signals and sent to the LED street lamps. After receiving the PWM modulation signals, the LED street lamps emit light of corresponding intensity. The s...

Abstract

The invention discloses a power-saving fuzzy control system and a control method for a LED streetlight. The system mainly comprises a multiplier, a converter, a fuzzy controller, a LED streetlight and a sensor. The multiplier is connected with the converter and used for setting the illumination intensity of the LED streetlight. The converter mainly is responsible for converting the inputted information into a digital signal and delivering the digital signal to the fuzzy controller. Having processed the received digital signal, the fuzzy controller converts the digital signal into a PWM signal and then delivers the PWM signal to the LED streetlight. The sensor observes the illumination intensity value of the LED streetlight in real time and delivers the illumination intensity value to the fuzzy controller. After fuzzification of the received information, the fuzzy controller performs fuzzy judgment on the received information according to fuzzy control rules and determines whether to send a new PWM modulation signal or not by the judged result so as to control the illumination intensity of the LED streetlight.

Description

technical field [0001] The invention relates to an LED street lamp power-saving system, in particular to a LED street lamp power-saving fuzzy control system and a control method thereof. Background technique [0002] As a new generation of light sources, LED lamps are quickly accepted by people for their advantages of energy saving, environmental protection, and long life, and gradually replace the status of traditional incandescent and fluorescent lamps. LED street light is a kind of low-illumination lamp, which is generally used for outdoor lighting at night. Due to its special working environment, it often needs to be in the working state for a long time, and it will still cause some waste of electric energy. [0003] To sum up, in view of the defects of the prior art, a fuzzy control system and a control method thereof for power saving of LED street lamps are particularly needed to solve the above-mentioned problems. Contents of the invention [0004] The purpose of t...
