西安交大可報(bào)溫報(bào)時(shí)電子鐘設(shè)計(jì)報(bào)告

1、電子系統(tǒng)設(shè)計(jì)報(bào)告電氣43 陳振斌 孫鵬程西安交通大學(xué)2017-5-20鬧鐘提示 1、 整體系統(tǒng)框圖S3、S4、S5鍵組合實(shí)現(xiàn)校正整點(diǎn)S2鍵切換顯示S1鍵切換模式數(shù)碼管閃爍報(bào)時(shí)報(bào)溫溫度顯示日歷校正定鬧功能日歷顯示時(shí)鐘顯示時(shí)鐘校正2、 系統(tǒng)工作原理基于單片機(jī)STC89C52與開發(fā)平臺(tái)KEIL軟件，利用C語(yǔ)言設(shè)計(jì)相關(guān)程序。期間配合使用DS1302時(shí)鐘芯片實(shí)現(xiàn)走時(shí)功能，使用溫度傳感器件DS18B20實(shí)現(xiàn)室溫測(cè)量功能，使用ISD1760語(yǔ)音芯片實(shí)現(xiàn)錄放音功能以及配合動(dòng)態(tài)顯示數(shù)碼將相關(guān)功能以可視形式呈現(xiàn)，并通過(guò)按鍵配合實(shí)現(xiàn)切換顯示、校時(shí)、定鬧等額外功能。S1、S2鍵執(zhí)行模式及顯示切換功能及S5確認(rèn)/關(guān)閉鬧

2、鐘功能時(shí)鐘、日歷校正及定鬧模塊（S3、S4、S5組合）鬧鐘提示（數(shù)碼管閃爍）定時(shí)中斷部分循環(huán)程序主程序循環(huán)時(shí)鐘、日歷顯示模塊整點(diǎn)報(bào)時(shí)報(bào)溫功能溫度顯示循環(huán)（關(guān)閉定時(shí)器）3、 軟件框圖開始各變量及時(shí)鐘、語(yǔ)音芯片初始化 4、 系統(tǒng)使用介紹：電路板上電后，初始狀態(tài)數(shù)碼管顯示時(shí)鐘；S1鍵切換模式，模式0為正常顯示模式，模式1為校正模式，并且取決于按下按鍵之前顯示部分依次進(jìn)入：時(shí)鐘校正、日歷校正、鬧鐘定時(shí)模塊；S2鍵切換顯示，依次為：時(shí)鐘、日歷、溫度；S3鍵在進(jìn)入校正模式有效，用于選擇校正位；S4鍵在進(jìn)入校正模式有效，用于對(duì)當(dāng)前校正位進(jìn)行數(shù)值改變，即“加1”功能；S5鍵在校正模式時(shí)，用于確認(rèn)校正，在鬧鐘閃

3、爍時(shí)，按下可關(guān)閉鬧鐘；S6為電路板重置鍵，終止程序；RST鍵為語(yǔ)音芯片重置鍵，中斷語(yǔ)音芯片工作。5、 已知部分缺陷及非完美解決方案：?jiǎn)栴}描述：進(jìn)入校正模式時(shí)，會(huì)出現(xiàn)數(shù)據(jù)讀取錯(cuò)亂，使得數(shù)碼顯示09以外的數(shù)字，如A、B、C、D等；在確認(rèn)校正時(shí)同樣會(huì)有幾率出現(xiàn)該問(wèn)題。推測(cè)原因：DS1302走時(shí)程序中數(shù)據(jù)會(huì)有過(guò)渡性變化，使得display_buffer數(shù)組的數(shù)據(jù)在讀取和置入時(shí)產(chǎn)生問(wèn)題?；蛑脭?shù)時(shí)有數(shù)據(jù)錯(cuò)誤。 解決方案：對(duì)顯示錯(cuò)亂部分重新進(jìn)行校時(shí)，該處將置零。此后可正常校正。6、 軟件編寫與調(diào)試時(shí)所遇到的問(wèn)題及解決方案：l 按鍵按下時(shí)程序多次執(zhí)行：利用“miaomiao”系列變量作為判定條件保證只執(zhí)行一次

4、程序；l 對(duì)顯示變量display_buffer直接進(jìn)行加一操作進(jìn)位產(chǎn)生錯(cuò)亂：引入buffer_temp數(shù)組，替代校正；l 語(yǔ)音芯片不能連續(xù)播放多段語(yǔ)音：每段播放后延時(shí)適當(dāng)時(shí)間；l 為使得”on”、” off” 的右下角顯示小數(shù)點(diǎn)時(shí)對(duì)SEGMENT直接進(jìn)行“位與”操作只能顯示o8.”、” of8”. 等：引入變量s過(guò)渡；l 整點(diǎn)報(bào)時(shí)會(huì)連續(xù)兩次播放語(yǔ)音：只在分鐘顯示為“59”時(shí)使得miaomiao_play變量為一，播放后置為零，保證只播放一次；l 報(bào)溫時(shí)可能讀取到設(shè)定工作溫度上限（39攝氏度）的溫度值且實(shí)際此時(shí)溫度在上限之內(nèi)：在tmread()函數(shù)里增加循環(huán)讀取部分直至讀到正常數(shù)值；l 其他組

5、組員(于晨曦同學(xué))提出的建議與提示：溫度讀取時(shí)間較長(zhǎng)不宜加入定時(shí)中斷顯示；每次顯示前對(duì)位碼或段碼（取決于置數(shù)順序）先置零，以解決數(shù)碼管殘影問(wèn)題。7、 PCB板原理圖及接線圖見驗(yàn)收文件夾PPT，由于打印問(wèn)題在此不作展示。8、 源程序代碼#include #include #include #include #define SEGMENT XBYTE0xdfff#define BIT_LED XBYTE0xbfff#define fosc 11.0592#define time0 2500#define uint unsigned int#define SEGMENT XBYTE0xdfff#de
