[Abstract]:Street lamp is one of the important municipal road lighting equipment, which can ensure the smooth passage of urban roads, improve the efficiency of traffic and transportation, and play a vital role in improving the living standards and environmental atmosphere of the city. But street lamps provide people with convenience and efficiency, but also consume a lot of electricity. Because the scale effect can bring great benefits even to the improvement of a small unit, the effective monitoring and management of street lamp lighting can bring significant energy-saving effect, traditional street lamp control design, There is no energy saving control research on the characteristics of light source, which results in unnecessary energy consumption and waste in light source control. According to the development trend of energy saving light source and information network, it is imperative to study the energy saving in the control link of street lamp light source. Firstly, the characteristic mechanism of LED is analyzed and studied, and the optical, electrical, thermal and parameters of LED are analyzed and introduced, so as to study the failure model of LED. The effects of various light failure modes on LED are analyzed in detail. Through theoretical research, the factors affecting LED light decay such as temperature, humidity, voltage, current and so on are found out. The mathematical model is established by the method of artificial neural network (ANN). The failure model of LED is explained in detail. Secondly, according to the characteristic mechanism and failure model of LED, the object control model suitable for this research is selected, and the corresponding expansion and change are made based on the static compensation control mode of light decay. The control mode of dynamic compensation for light decay is introduced. The control methods, the design of the control process and the characteristics of the two control modes are described. It is proved that both static compensation and dynamic compensation are indispensable and complementary. Finally, according to the control strategy of static compensation and dynamic compensation, a street lamp control system is designed, which can compensate for LED light decline. The design of LED power driver, dimming control circuit and optical attenuation compensation control module is completed. This paper introduces the protocol of Zig Bee wireless network control technology, network technology and other core technologies. The wireless control function is embedded in the street lamp energy saving system, and the wireless control of the street lamp energy saving system is realized. In order to realize the demand of energy saving of LED, the characteristics of light decay of LED are studied. The methods of dynamic compensation and static compensation of LED are adopted, and the results of energy saving control system are obtained according to the characteristics of light source. It is proved that the energy saving effect of dynamic control system for light decay compensation is remarkable.
