【摘要】 我国人口众多、资源相对紧张，能源紧缺制约了国民经济的发展。因此，经济要实现持续、快速、健康发展，必须改变经济增长方式，由粗放型向集约型转变，节能是国家发展经济的一项长远战略方针。照明用电量在总耗电量中所占比例逐渐增大，所以进行照明节能控制是很有实际意义的。本文分别从课题产生的背景和研究意义、方案的选择与确立、系统软硬件设计、模糊控制思想在照明节能系统中的实现等方面展开整个照明节能系统的阐述。在方案的选择和确立中，对常用照明灯具进行了类型分析，并选出具有代表性的两种电光源。通过调节电压去检测其照度的变化情况最后得到电压与照度变化的特性关系，论证了调节电压可达到调节照度的可行性。经过查阅文献对当前国内外常用的照明节能控制器调压调光方法进行分析并对其优缺点逐一比较，最后根据以往调压调光方法的优缺点提出了一种新型的方案——即晶闸管分级调压调光法，并给出了模糊控制思想在此照明节能系统中的应用方法。本文还阐述了照明节能系统的整体架构以及软、硬件设计。系统的硬件包括过零检测电路、晶闸管调压组合电路、电压检测电路等和分别以P89LPC935单片机为核心的上位机外围控制电路以及89S51单片机为核心的下位机外围控制电路的设计。最后总结了全文工作并说明了系统中的一些不足之处。更多还原

【Abstract】 With large population and the lack of resources from the general situation,the problem of energy restricts the development of national economy.To realize the continuous,rapid and healthy development,we must change the pattern of economy development. To change the extensive development to the intensive development must take the energy-saving as the long-term strategy of national economy development.lighting energy-consumption consumes main part in the whole consumption of energy. So the control of lighting energy-saving is very important.This dissertation describes the system of lighting energy-saving from the background,the sense of research,the choice of the scheme,the design of software and hardware of the system and the thought of fuzzy logic application in lighting energy-saving system.In the process of the choice of scheme,we analyses the type of lighting fixture in common use and take two representative electrical lamp-houses as examples to obtain the characteristic relation of voltage and lumination with adjusted voltage detecting lumination variety. The feasibility of variety lumination with adjusted voltage is demonstrated in this dissertation. The advantage and disadvantage of various normal lighting energy-saving schemes with variety lumination with asjusted voltage also is analysed in this dissertation.Then a new scheme of this typeof system--thyristor multi-level asjusted voltage based lumination asjustment isdesigned in this dissertation.The applicant about the lighting energy-saving system based on fuzzy logic theory also described in this dissertation.Then this dissertation describes the whole framework of the dimming energy-saving ,the hardware and the software design. The hardware system contains zero crossing detection circuit,thyristor adjust combinational circuit,voltage detection circuit and makes use of P89LPC935 as the core of the upper computer outside control circuit,makes use of 89S51 as the core of lower computer outside control circuit.Then this paper summarizes the whole design,and discusses some defects of the system.更多还原
