【摘要】：隨著城市建設(shè)和道路交通的高速發(fā)展,人們對節(jié)能路燈照明產(chǎn)品的需求與日俱增。太陽能LED路燈兼具有太陽能無污染、可循環(huán)利用的長處及LED照明高效節(jié)能、環(huán)保、壽命長和容易控制等優(yōu)點(diǎn),是當(dāng)今路燈照明用電研究的主題,顯示出巨大的發(fā)展前景。為能實(shí)現(xiàn)太陽能LED路燈的長壽命以及高效率,專家學(xué)者對于太陽能LED路燈控制系統(tǒng)做了很多深入研究。目前研發(fā)出對太陽能LED路燈有幫助的智能功能有12/24V自適應(yīng)、分時段放電功能、手持機(jī)控制功能、電池低壓自動降功率功能、MPPT充電功能、記憶功能等,但由于在當(dāng)前拓?fù)浣Y(jié)構(gòu)下,多個功能在實(shí)現(xiàn)上具有互相矛盾的需求、難以同時實(shí)現(xiàn),現(xiàn)有的產(chǎn)品一般只具有上述功能中的某幾種。在綜合考慮整個系統(tǒng)的效率、空載損耗、成本的情況下,本文用一種新的拓?fù)浣Y(jié)構(gòu)設(shè)計(jì)了一種通用性較強(qiáng)的太陽能LED路燈智能控制系統(tǒng),不僅實(shí)現(xiàn)了現(xiàn)有控制系統(tǒng)能實(shí)現(xiàn)的全部功能,而且還獨(dú)創(chuàng)性地實(shí)現(xiàn)了陰雨天自動降功率以及自適應(yīng)晨亮功能。智能控制系統(tǒng)由控制器和手持機(jī)構(gòu)成,控制器以雙向同步整流BUCK/BOOST電路作為電源變換的主電路,減少了開關(guān)器件的損耗,也減小了體積和成本;在該電路的基礎(chǔ)上引入最大功率點(diǎn)跟蹤算法來控制充電過程,以此來提高系統(tǒng)對太陽能的利用率;通過完善的過充和過放保護(hù)手段,延長鋰電池的壽命;在放電情況下,通過電流負(fù)反饋保持LED電流恒定,使光照穩(wěn)定無閃爍、延緩LED的光衰;控制器還具有自動判斷日夜并切換充電和放電狀態(tài)的功能;而且還能自動分析冬夏夜晚長度變化并合理規(guī)劃夜晚亮燈時段變化,使得在人們最需要的時候能提供足夠的照明。另外,通過手持機(jī)可以設(shè)置太陽能板電壓、電池保護(hù)電壓、LED燈電流、夜晚分時段改變LED燈亮度等工作參數(shù),從而使系統(tǒng)可以適應(yīng)不同規(guī)格和特性的太陽能板、電池、LED燈;通過手持機(jī)還可以讀取控制器的運(yùn)行參數(shù),既可以評估系統(tǒng)工作情況,還可以通過一段時間的過充、過放次數(shù)評估太陽能板及鋰電池容量設(shè)置合理與否。本文在結(jié)合大量相關(guān)文檔以及工程師提供的技術(shù)指標(biāo)的情況下,提出了太陽能LED路燈智能控制系統(tǒng)的設(shè)計(jì)方案,闡述了智能控制系統(tǒng)各個部分的實(shí)現(xiàn)方法以及硬件、軟件設(shè)計(jì)思想,最大程度上去實(shí)現(xiàn)太陽能LED路燈的智能化控制,經(jīng)實(shí)驗(yàn)室和現(xiàn)場實(shí)驗(yàn)表明,所設(shè)計(jì)的智能控制系統(tǒng)通用性強(qiáng)、效率高、工作穩(wěn)定,應(yīng)用于路燈照明能帶來巨大的社會效益和經(jīng)濟(jì)價值。
[Abstract]:With the rapid development of urban construction and road traffic, the demand for energy-saving street lamp lighting products is increasing. Solar LED street lamp has the advantages of solar energy pollution, recycling, LED lighting, high efficiency, energy saving and environmental protection. The advantages of long life and easy control are the subject of the research on street lamp lighting and electricity, which shows great development prospects. In order to realize the long life and high efficiency of solar LED street lamp, Experts and scholars have done a lot of in-depth research on the solar LED streetlight control system. At present, the intelligent functions that have been developed to help solar LED street lamps are 12 / 24V adaptive, phased discharge, handheld control. Battery low-voltage automatic power reduction function MPPT charging function, memory function, etc., but in the current topology, many functions have conflicting requirements in the realization, so it is difficult to realize simultaneously. Existing products generally have only one of the above functions. When considering the efficiency, no-load loss, and cost of the whole system, In this paper, a solar LED street lamp intelligent control system is designed with a new topology, which not only realizes all the functions that the existing control system can achieve. The intelligent control system is composed of controller and handheld mechanism. The controller uses bi-directional synchronous rectifier BUCK/BOOST circuit as the main circuit of power conversion. On the basis of the circuit, the maximum power point tracking algorithm is introduced to control the charging process to improve the utilization of solar energy. The lifetime of lithium battery is prolonged by perfect overcharge and overdischarge protection, and the LED current is kept constant through negative feedback of current under discharge condition, which makes the illumination stable and does not flicker, and delays the light decay of LED. The controller also has the function of automatically judging the day and night and switching the state of charge and discharge, and can also automatically analyze the length of the winter and summer nights and reasonably plan the change of the night light period. In addition, the handheld can set solar panel voltage, battery protection voltage, LED lamp current, change the brightness of LED lamp in different periods of time at night, etc. So that the system can adapt to different specifications and characteristics of solar panels, battery LED lights; through the handset can also read the operating parameters of the controller, not only can evaluate the system's performance, but also through a period of time to overcharge, In this paper, based on a large number of relevant documents and technical specifications provided by engineers, a design scheme of solar LED street lamp intelligent control system is proposed. The realization method of each part of the intelligent control system and the design idea of hardware and software are expounded. The intelligent control of solar LED street lamp is realized to the greatest extent. The laboratory and field experiments show that, The designed intelligent control system has the advantages of high generality, high efficiency and stable operation. The application of the intelligent control system to street lighting can bring great social and economic value.
