摘  要

 如何很好的節約和利用能源，特別是可持續性能源，一直是人類所面臨的問題。所以研究智能化家庭住宅里的能源如何被更有效的節約和利用，也就有著十分現實和長遠的意義。而家用太陽能熱水器就是一個節約能源，有效利用能源的典型。
 隨著人民生活水平的日益提高，智能化家庭住宅模式也將在我們興起、發展和完善。所以實現對家用設備的智能化控制也就成了一種有益的、必要的、積極的探索和研究。
 本問按照智能化太陽能熱水器控制系統的開發為線索，通過幾個章節來闡述：首先闡述了智能化太陽能熱水器控制系統開發的必要性，分析了國內外太陽能熱水器及其控制的現實狀況；其次介紹了智能化太陽能熱水器控制系統的開發核心--PIC單片機；第三章介紹了智能化太陽能控制系統的硬件開發，第四章介紹了軟件設計流程，最后是全文的小結。
 
關鍵詞：可持續能源；太陽能熱水器；智能化
Abstract

 To economize and utilize energy resource，especially the lasting energy resource，is a problem that humankind has faced．So it is so realistic and significant to research how to economize and utilize energy resource in home using．And the Solar Water Heater is a good example in economizing and utilizing energy resource．
 As continually progress in human life and technology and the using of electronic technique in every field．So to make the intelligentized control of residential equipment into reality is a necessary active thing．
 Following the clue of the development phases of the intelligentized control system of the Solar Water Heater. The further divided into 5 chapters: the first chapter discusses the essentiality of the intelligentized control system of the Solar Water Heater; chap.2 introduce the core of the intelligentized control system of the Solar Water Heater--the PIC single Chip Microcopy; chap.3 introduce the hardware and exploitation and design of the intelligentized control system of the Solar Water Heater; chap.4 introduce the software exploitation and design of the intelligentized control system of the Solar Water Heater. The last chapter is the summary of the whole paper.
