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
The present invention relates to a kind of LED electricity saving of road lamp system, specially refer to a kind of LED electricity saving of road lamp Fuzzy control system and control method thereof.

Summary of the invention
The purpose of this invention is to provide a kind of LED electricity saving of road lamp Fuzzy control system and control method thereof,, make the LED street lamp be in the state of low consumption all the time, be issued to purpose of energy saving in the prerequisite that guarantees illuminating effect through the intensity of illumination of real-time monitored LED street lamp.
The technical problem that the present invention solved can adopt following technical scheme to realize:
A kind of LED electricity saving of road lamp Fuzzy control system is characterized in that said system comprises multiplier, transducer, fuzzy controller, LED street lamp and transducer; Said multiplier is connected with transducer; Be used to set the intensity of illumination of LED street lamp; Transducer is responsible for the information translation of input is digital signal and passes to fuzzy controller; Fuzzy controller changes received digital signal into pwm signal after treatment and is passed to the LED street lamp, the intensity of illumination numerical value of sensor in real time observation LED street lamp, and pass to fuzzy controller.
In one embodiment of the invention, said fuzzy controller is an embedded computer.
3, a kind of LED electricity saving of road lamp fuzzy control method is characterized in that said method comprises the steps:
1) at first through the intensity of illumination of multiplier setting LED street lamp, transducer is a digital signal with the intensity of illumination information translation of input, and sends to fuzzy controller;
2) after fuzzy controller receives the digital signal of transducer, treatedly convert the PWM modulation signal into, and be passed to the LED street lamp, the illumination that the LED street lamp sends specified intensity according to the signal that receives;
3) the LED street lamp begin luminous after, transducer is responsible for the intensity of illumination numerical value of real-time monitored LED street lamp, and sends it to fuzzy controller;
4) after fuzzy controller carries out Fuzzy processing to the information that receives, carry out fuzzy Judgment according to fuzzy control rule, and determine whether sending the intensity of illumination that new PWM modulation signal is controlled the LED street lamp according to judged result.
