【摘要】：在科技日益發(fā)展的今天,人們對(duì)生活的質(zhì)量提出了更高的要求,生活的舒適性成為首選。與此同時(shí),能源以前所未有的速度在消耗,幾近枯竭,為此,綠色、環(huán)保、可持續(xù)發(fā)展的觀念被提到日程,深入人心。作為人們生產(chǎn)生活的重要能耗--電氣照明的控制系統(tǒng)應(yīng)用越來(lái)越廣泛,同時(shí)期控制手段也在不斷變化。順應(yīng)了智能建筑的發(fā)展需求。健康舒適的綠色照明有益于人們的身心健康,成為智能建筑照明設(shè)計(jì)實(shí)現(xiàn)的中心目標(biāo),以電氣照明的方式以及控制策略等著手進(jìn)行考慮,從而進(jìn)行能源的可持續(xù)性以及節(jié)約性。文章將建筑照明智能化控制做為核心,主要從以下幾個(gè)方面進(jìn)行研究:1.控制系統(tǒng)的總體設(shè)計(jì)方案針對(duì)建筑的特點(diǎn)和功能及使用者的活動(dòng)規(guī)律,給出照明控制系統(tǒng)的總體設(shè)計(jì)方案,在滿足綠色、環(huán)保、智能要求的前提下,力求結(jié)構(gòu)簡(jiǎn)單,布線靈活、設(shè)置便捷、運(yùn)行成本及管理維護(hù)成本較低。照明控制系統(tǒng)的核心利用微型計(jì)算機(jī)進(jìn)行控制,通過(guò)不間斷的采集對(duì)系統(tǒng)的輸入以及輸出電壓進(jìn)行分析,同時(shí)將其和系統(tǒng)內(nèi)部所設(shè)定的最優(yōu)電壓閥值進(jìn)行對(duì)比分析,若兩者之間存在差異,還需要采用系統(tǒng)計(jì)算模塊來(lái)摘開(kāi)調(diào)解,進(jìn)而使得照明的輸出電壓達(dá)到最優(yōu)。2.控制系統(tǒng)的硬件設(shè)計(jì):根據(jù)提出的控制系統(tǒng)的總體設(shè)計(jì)方案,完成硬件電路部分的單元電路設(shè)計(jì)和器件的選擇,包括光照采集驅(qū)動(dòng)設(shè)計(jì)、紅外采集驅(qū)動(dòng)設(shè)計(jì)、繼電器控制電路等。本設(shè)計(jì)采用了模糊PID控制算法,利用該算法完成輸入電壓與系統(tǒng)設(shè)定的照明電壓閾值進(jìn)行比較,達(dá)到燈具的照度與室內(nèi)中的人數(shù)相適應(yīng)的目的,以期到最佳的亮度效果。3.控制系統(tǒng)的軟件設(shè)計(jì):根據(jù)控制系統(tǒng)的總體設(shè)計(jì)方案和硬件電路的功能要求,按照模塊化的設(shè)計(jì)思路,首先完成軟件整體設(shè)計(jì),然后根據(jù)功能要求劃分模塊單元,對(duì)每一功能模塊分別進(jìn)行設(shè)計(jì),這種設(shè)計(jì)思路非常有利于完成后期的測(cè)試環(huán)節(jié)。4.控制系統(tǒng)的控制算法設(shè)計(jì):根據(jù)軟硬件設(shè)計(jì)功能要求,本文采用了模糊PID控制算法,該算法對(duì)智能照明控制系統(tǒng)的輸入電壓進(jìn)行控制,使照明亮度達(dá)到最佳狀態(tài),并將模糊PID控制算法與傳統(tǒng)的PID算法進(jìn)行對(duì)比。
[Abstract]:With the development of science and technology, people demand higher quality of life, and the comfort of life becomes the first choice. At the same time, energy is consumed at an unprecedented rate, almost exhausted. Therefore, the concept of green, environmental protection and sustainable development is on the agenda. As the important energy consumption of people's production and life, electric lighting control system is applied more and more widely. Meet the development needs of intelligent buildings. The healthy and comfortable green lighting is beneficial to people's physical and mental health and becomes the central goal of the lighting design of intelligent buildings. The way of electric lighting and control strategy are taken into consideration so as to make energy sustainable and economize. In this paper, intelligent control of building lighting as the core, mainly from the following aspects: 1. The overall design scheme of the control system is based on the characteristics and functions of the building and the activity rules of the users. The overall design scheme of the lighting control system is given. On the premise of meeting the requirements of green, environmental protection and intelligence, the control system strives for simple structure and flexible wiring. Easy to set up, running cost and management and maintenance costs are low. The core of the lighting control system is controlled by microcomputer. The input and output voltages of the system are analyzed through continuous acquisition, and the optimal voltage threshold is compared with the optimal voltage threshold set within the system. If there is a difference between the two, it is necessary to use the system calculation module to remove and adjust, thus making the output voltage of illumination to reach the optimum. 2. 2. The hardware design of the control system: according to the overall design scheme of the proposed control system, the unit circuit design and the device selection of the hardware circuit are completed, including the illumination acquisition driver design, the infrared acquisition driver design, Relay control circuit, etc. The fuzzy PID control algorithm is used in this design, and the input voltage is compared with the lighting voltage threshold set by the system. The illumination of lamps and lanterns is suitable to the number of people in the room, in order to achieve the best luminance effect. The software design of the control system: according to the overall design scheme of the control system and the function requirement of the hardware circuit, according to the modular design idea, the whole software design is completed first, and then the module unit is divided according to the function requirement. Design each functional module separately, this design idea is very helpful to complete the later test link. 4. 4. The control algorithm design of the control system: according to the function requirement of hardware and software design, the fuzzy PID control algorithm is adopted in this paper. The algorithm controls the input voltage of the intelligent lighting control system to make the illumination brightness reach the best state. The fuzzy PID control algorithm is compared with the traditional PID algorithm.
