基于PLC的智能照明控制系统设计(任务书,开题报告,论文说明书11000字)
摘  要
 随着社会的发展人们对生活质量的要求越来越高，为方便生活人们越来越多的在各个场所引入照明设备，照明在能耗中所占的比例日益增加。为了达到方便生活的目的，这些照明设备有时会彻夜开着，从而造成了大量电力能源的浪费。据统计，在楼宇能量消耗中，仅照明就占33%，因此照明节能日显重要。现在国内外普及使用的节能开关基本有声控型、触摸型、感光型等。这几种开关各有自己的弊端，如声控型不适合环境嘈杂场所、触摸型虽然能自动关闭但不能自动打开、感光型开关在无人期间不能自动关闭……由此研究设计一种既智能又节能的控制系统来替代现有的产品是一件极其有意义的工作。
智能照明控制系统在确保灯具能够正常工作的条件下，给灯具输出一个最佳的照明功率，既可减少由于过压所造成的照明眩光，使灯光所发出的光线更加柔和，照明分布更加均匀，又可大幅度节省电能，智能照明控制系统节电率可达20%-40%。智能照明控制系统它可在照明及混合电路中使用，适应性强，能在各种恶劣的电网环境和复杂的负载情况下连续稳定地工作，同时还将有效地延长灯具寿命和减少维护成本。
通过对照明智能控制系统的分析，进而没计出整个控制系统中各时段的运行时序。系统硬件设计。根据不同时段照明的需求，设计硬件线路连接控制。应用PLC编程软件设计出程序。通过PLC控制不同路段照明灯及景观灯，使其能够按预先设计的时序运行。

Abstract

With the development of society, people's demand for quality of life is getting higher and higher. In order to facilitate people's life, more and more lighting devices are introduced into various places, and the proportion of lighting in energy consumption is increasing. In order to achieve the purpose of convenient life, these lighting devices sometimes stay on all night, resulting in a large amount of waste of power and energy. According to statistics, lighting alone accounts for 33% of building energy consumption, so lighting energy saving is becoming more and more important. Nowadays, the energy-saving switches widely used at home and abroad are basically voice-controlled, touch-sensitive and photosensitive. These switches have their own drawbacks, such as voice-controlled switch is not suitable for noisy environment, touch-type switch can automatically turn off but can not automatically turn on, photosensitive switch can not automatically turn off when no one is around... Therefore, it is very meaningful to study and design an intelligent and energy-saving control system to replace the existing products.
Intelligent lighting control system can output an optimum lighting power to the lamp under the condition of ensuring the normal operation of the lamp. It can not only reduce the lighting glare caused by overvoltage, make the light emitted by the lamp softer, distribute the lighting more evenly, but also save electricity greatly. The energy saving rate of the intelligent lighting control system can reach 20%-40%. Intelligent lighting control system can be used in lighting and hybrid circuits with strong adaptability. It can work continuously and steadily under various harsh power network environments and complex loads. It will also effectively prolong lamp life and reduce maintenance costs.
Through the analysis of the intelligent lighting control system, the running sequence of each period in the whole control system is not calculated. System hardware design. According to the requirements of lighting in different periods, the hardware circuit connection control is designed. The program is designed by using PLC programming software. The lighting and landscape lights of different sections are controlled by PLC, so that they can run in pre-designed time sequence.
