【摘要】：在科技日益发展的今天,人们对生活的质量提出了更高的要求,生活的舒适性成为首选。与此同时,能源以前所未有的速度在消耗,几近枯竭,为此,绿色、环保、可持续发展的观念被提到日程,深入人心。作为人们生产生活的重要能耗--电气照明的控制系统应用越来越广泛,同时期控制手段也在不断变化。顺应了智能建筑的发展需求。健康舒适的绿色照明有益于人们的身心健康,成为智能建筑照明设计实现的中心目标,以电气照明的方式以及控制策略等着手进行考虑,从而进行能源的可持续性以及节约性。文章将建筑照明智能化控制做为核心,主要从以下几个方面进行研究:1.控制系统的总体设计方案针对建筑的特点和功能及使用者的活动规律,给出照明控制系统的总体设计方案,在满足绿色、环保、智能要求的前提下,力求结构简单,布线灵活、设置便捷、运行成本及管理维护成本较低。照明控制系统的核心利用微型计算机进行控制,通过不间断的采集对系统的输入以及输出电压进行分析,同时将其和系统内部所设定的最优电压阀值进行对比分析,若两者之间存在差异,还需要采用系统计算模块来摘开调解,进而使得照明的输出电压达到最优。2.控制系统的硬件设计:根据提出的控制系统的总体设计方案,完成硬件电路部分的单元电路设计和器件的选择,包括光照采集驱动设计、红外采集驱动设计、继电器控制电路等。本设计采用了模糊PID控制算法,利用该算法完成输入电压与系统设定的照明电压阈值进行比较,达到灯具的照度与室内中的人数相适应的目的,以期到最佳的亮度效果。3.控制系统的软件设计:根据控制系统的总体设计方案和硬件电路的功能要求,按照模块化的设计思路,首先完成软件整体设计,然后根据功能要求划分模块单元,对每一功能模块分别进行设计,这种设计思路非常有利于完成后期的测试环节。4.控制系统的控制算法设计:根据软硬件设计功能要求,本文采用了模糊PID控制算法,该算法对智能照明控制系统的输入电压进行控制,使照明亮度达到最佳状态,并将模糊PID控制算法与传统的PID算法进行对比。
[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.
