【正文】 1 摘 要 在 科學(xué)技術(shù)飛速發(fā)展的 21 世紀(jì)里， 電子智能家居產(chǎn)業(yè) 獲得 了迅速發(fā)展 。 很多智能 電器 設(shè)備都 趨于 智能化、 人性化 ， 這些電器設(shè)備大部分都含有 CPU 控制器也有 可能 是 單片機(jī)。 單片機(jī)以其高可靠性、高性價(jià)比、低電壓、低功耗等一系列優(yōu)勢(shì) ，近幾年得到迅猛發(fā)展和大范圍推廣， 普遍 應(yīng)用于工業(yè)控制系統(tǒng)、 辦公設(shè)備 、交通出行、 日常消費(fèi)類 產(chǎn)物 和玩具等。并且已經(jīng)深入到 各行業(yè)發(fā)展 的各個(gè)環(huán)節(jié)以及人民 日常 生活的各個(gè)方面，如車間流水線控制、 交通出行記錄儀等。 智能家居的發(fā)展最得力于各種傳感器技術(shù)的發(fā)展，傳感器的發(fā)明解決了對(duì)被測(cè)對(duì)象的某一特定信息實(shí)施無人自動(dòng)監(jiān)測(cè)或檢出功能，并能讓其使用特定方式轉(zhuǎn)化成與之對(duì)應(yīng)的可接受信號(hào)源的元器件。智能家居最主要就是減少人工投入，但能更加準(zhǔn)確的服務(wù)于人們的日常生活 。 純水機(jī)控制面板系統(tǒng)利用單片機(jī) 系統(tǒng) 進(jìn)行控制，實(shí)時(shí)傳感器進(jìn)行監(jiān)控，外加信號(hào)傳輸電路和顯示電路。深度分析了純水機(jī)的工作原理， 這次畢業(yè)設(shè)計(jì)也 闡述了單片機(jī)設(shè)計(jì)的 優(yōu) 點(diǎn)與缺點(diǎn)， 從而更加充分 體現(xiàn)出 用單片機(jī) 能使小家電實(shí)用便攜、操作簡(jiǎn)單的長(zhǎng)處。 這次設(shè)計(jì)選用的 Protues仿真軟件是 Labcenter公司設(shè)計(jì)出的集電子電路分析、電路仿真系統(tǒng)于一體的軟件。市面上有許多款電子仿真軟件，像 WEB軟件、Multisim仿真軟件等。雖然這些軟件都簡(jiǎn)單實(shí)用，但是它們不能與單片機(jī)進(jìn)行很好的配合。而 PROTEUS軟件就可以和單片機(jī)完美的結(jié)合，實(shí)現(xiàn)單片機(jī)及其電路的各種功能。因此選擇了 PROTEUS軟件。 關(guān)鍵詞 ： 單片機(jī)；傳感器；純水機(jī) ； Protues 仿真 2 ABSTRACT In the rapid development of science and technology in twentyfirst Century, the smart home industry has been rapid development. Many intelligent electrical appliances tend to be intelligent, humane, most of these electrical appliances are contained in the CPU controller may also be a single chip. Single chip microputer to the high reliability, high price, low voltage, low power consumption, and a series of advantages, in recent years obtained rapid development and promotion of a wide range, widely used in industrial control system, office equipment, transportation, daily consumption class products and toys etc.. And has perated into all aspects of the development of various industries and people39。s daily lives, such as workshop assembly line control, traffic travel, etc.. The development of smart home the most effective in the development of sensor technology, sensor of the invention solves the a particular information of an object to be measured in the implementation of unmanned automatic monitoring or detection function, and can make the use a specific way into corresponding acceptable signal source ponents. Smart home is the most important is to reduce labor input, but can be more accurate service to people39。s daily life. The pure water machine control panel system is controlled by a single chip microputer system, a realtime sensor is monitored, an external signal transmission circuit and a display circuit are used. Depth analysis of the principle of pure water machine, the graduation design also describes the singlechip design of the advantages and disadvantages, and thus more fully reflect with single chip to enable the strengths of small household electrical appliances, portable and practical, simple operation. This design chooses the Protues simulation software is the software which the Labcenter pany designs the collection electronic circuit analysis, the circuit simulation system in one body. There are many electronic simulation software on the market, such as WEB software, Multisim simulation software, etc.. Although these software are simple and practical, but they can not be a good match with the microcontroller. And PROTEUS software can and the perfect bination of SCM, the realization of the various functions of SCM and its circuit. So select the 3 PROTEUS software. Keywords: microcontroller。 sensor。 water machine。 Protues simulation 4 目 錄 1 緒論 ............................................................. 1 純水機(jī)發(fā)展現(xiàn)狀以及發(fā)展趨勢(shì) ................................. 1 產(chǎn)品現(xiàn)狀 ......................................................................................... 1 產(chǎn)品發(fā)展 ....................................................................................... 1 設(shè)計(jì)的內(nèi)容 .................................................. 2 2 設(shè)計(jì)思想和方案 .................................................
