【正文】 方案 2使用的 AT89C51 單片機(jī)在以前接觸過(guò),較為了解,使用起來(lái)比較簡(jiǎn)單方便。 方案 2: 以 單片機(jī) AT89C51 為核心, 采用 集成芯片 完成外圍電路功能 。以單片機(jī)為控制核心 ,達(dá)到設(shè)定的水溫時(shí),進(jìn)行語(yǔ)音播報(bào)。 主要性能指標(biāo) ( 1)以單片機(jī)為控制核心。鍵盤輸入及控制系統(tǒng)運(yùn)作 本設(shè)計(jì)定位為具有語(yǔ)音播報(bào)功能的水溫控制系統(tǒng),系統(tǒng)是將 AT89C51 單片機(jī)作為核心進(jìn)行設(shè)計(jì)的, AT89C51 的強(qiáng)大功能將完成接收鍵盤的指令信號(hào),接受數(shù)據(jù)收集芯片的收集到的實(shí)時(shí)數(shù)據(jù),進(jìn)行處理之后將要第一章 引言 2 顯示的部分傳送至顯示屏,并可根據(jù)需要控制語(yǔ)音輸出,根據(jù)預(yù)先設(shè)定的指令控制實(shí)現(xiàn)電路調(diào)整水溫。例如,現(xiàn)代化的泳池,當(dāng)前社會(huì)在實(shí)用性的基礎(chǔ)上更加講究舒適性,表現(xiàn)在室內(nèi)泳池上,就是泳池 的 水溫要保持在一個(gè)適當(dāng)?shù)姆秶鷥?nèi),以使身處泳池之中人的體表感官保持舒適;在家居生活中,技術(shù)較新的產(chǎn)品為了在性能上出眾,以達(dá)到增加銷量的目的,越來(lái)越多的人性化設(shè)計(jì)開始使用到家電之中,以電飯煲為例,現(xiàn)在 的電飯煲不在簡(jiǎn)簡(jiǎn)單單的能煮飯,如果飯煮好后主人沒(méi)能及時(shí)將飯盛出,電飯煲會(huì)根據(jù)溫度進(jìn)行自身調(diào)節(jié), 以使其中的飯始終保持在適宜食用的溫度范圍內(nèi),這其中用到的就是溫度控制。 關(guān)鍵字 : 語(yǔ)音播報(bào) , 水溫控制 , 單片機(jī) , 芯片 , 繼電器 摘 要 II Abstract Paper describes with speech function of the water temperature control system is the basis of mature framework design, the current system frame, design of the main difference lies in the system of each part of the unit circuit choose different devices. So, this paper will first from the whole framework of the choice of hardware to set the overall circuit, then will describe each unit circuit feasible ponents, in contrast to determine a priority. According to the design to after software program design. Are determined already AT89C51 singlechip microputer as the core of the system design, the strong function of AT89C51 will plete the signals received keyboard, accept data collection of chip to collect data in real time, to deal with that is to be revea LED after the part is sent to a display screen, , and based on the need to control speech output, according to the predetermined mand control realization circuit temperature adjustment. Speech broadcast of the integrated chip, for voice foreign transmission, choose ISD4004 largely optimizes the system, ISD4004 USES is the direct simulation amount storage technology, this technology can directly to the advantage of the simulation data entry, namely speech broadcast content can direct input part, without modulus outfit change, storage, and mathematical model with change, not only simplify the process, and minimize distortion, output effect is good. Data acquisition chip will use DS18B20, DS18B20 outstanding characteristic is no mathematical model with change, can directly access microcontroller, reduce signal distortion. Control realize part will use the relay, the number of single chip microputer by small electric current flows through to relay to control. Rely on the above design, the system will be efficient, stable realize data acquisition, processing, output, and realize the speech broadcast, temperature control and constant. Key words: speech broadcast , water temperature control , singlechip microputer, chip, relay目 錄 III 目錄 摘 要 .......................................................
