北京交大單片機(jī)課程設(shè)計(jì)多路監(jiān)控報(bào)警系統(tǒng)

1、單片機(jī)課程設(shè)計(jì) 多路監(jiān)控報(bào)警系統(tǒng) 多路監(jiān)控報(bào)警系統(tǒng)一、 實(shí)驗(yàn)?zāi)康? 了解A/D芯片TLC0809轉(zhuǎn)換性能及編程方法。2 掌握A/D轉(zhuǎn)換器與單片機(jī)的接口方法3 學(xué)會(huì)使用A/D轉(zhuǎn)換器進(jìn)行電壓信號(hào)采集。二、 設(shè)計(jì)任務(wù)及要求 利用串行模/數(shù)轉(zhuǎn)換芯片TLC0809、SST89E58及液晶顯示器，設(shè)計(jì)完成一個(gè)數(shù)字電壓多路監(jiān)控報(bào)警系統(tǒng)。要求： 數(shù)字電壓多路監(jiān)控報(bào)警系統(tǒng)可測(cè)量05V輸入電壓，電壓值通過液晶輪流顯示，并根據(jù)設(shè)置的限定值對(duì)輸入超出額度的路端警報(bào)提示。三、 工作原理及設(shè)計(jì)思路多路監(jiān)控報(bào)警系統(tǒng)的設(shè)計(jì)由A/D轉(zhuǎn)換、數(shù)據(jù)處理及顯示控制等組成。A/D轉(zhuǎn)換由集成電路TLC0809完成，利用TLC0809將模擬

2、電壓轉(zhuǎn)換為數(shù)字量，經(jīng)單片機(jī)將數(shù)字量轉(zhuǎn)換成對(duì)應(yīng)的電壓值，并通過液晶顯示輸出。四、 系統(tǒng)特點(diǎn)本系統(tǒng)可以每一路獨(dú)立設(shè)置最高最低的電壓值，并對(duì)每一路電壓進(jìn)行監(jiān)控報(bào)警，對(duì)超出范圍內(nèi)的電路顯示對(duì)應(yīng)路值，并用LED燈和蜂鳴器表示不同的路值。五、 硬件電路設(shè)計(jì)及原理1、ADC0809(1)、ADC0809管腳圖及時(shí)序圖： 該ADC0809數(shù)據(jù)采集部分是單片CMOS器件，它具有8位模擬數(shù)字轉(zhuǎn)換器，8通道多路復(fù)用器和微處理器兼容控制邏輯。8位A / D轉(zhuǎn)換器采用逐次逼近作為轉(zhuǎn)換技術(shù)。根據(jù)時(shí)序電路的分析，可以完成單片機(jī)編程。該系統(tǒng)在工作時(shí)，單片機(jī)將產(chǎn)生串行時(shí)鐘，并按時(shí)序發(fā)送和接受數(shù)據(jù)位。由上圖可知，ADC0809由

3、一個(gè)8路模擬開關(guān)、一個(gè)地址鎖存與譯碼器、一個(gè)A/D轉(zhuǎn)換器和一個(gè)三態(tài)輸出鎖存器組成。多路開關(guān)可選通8個(gè)模擬通道，允許8路模擬量分時(shí)輸入，共用A/D轉(zhuǎn)換器進(jìn)行轉(zhuǎn)換。三態(tài)輸出鎖器用于鎖存A/D轉(zhuǎn)換完的數(shù)字量，當(dāng)OE端為高電平時(shí)，才可以從三態(tài)輸出鎖存器取走轉(zhuǎn)換完的數(shù)據(jù)。IN0IN7：8條模擬量輸入通道 ADC0809對(duì)輸入模擬量要求：信號(hào)單極性，電壓范圍是05V，若信號(hào)太小，必須進(jìn)行放大；輸入的模擬量在轉(zhuǎn)換過程中應(yīng)該保持不變，如若模擬量變化太快，則需在輸入前增加采樣保持電路。 地址輸入和控制線：4條 ALE為地址鎖存允許輸入線，高電平有效。當(dāng)ALE線為高電平時(shí)，地址鎖存與譯碼器將A，B，C三條地址線的

4、地址信號(hào)進(jìn)行鎖存，經(jīng)譯碼后被選中的通道的模擬量進(jìn)轉(zhuǎn)換器進(jìn)行轉(zhuǎn)換。A，B和C為地址輸入線，用于選通IN0IN7上的一路模擬量輸入。數(shù)字量輸出及控制線：11條 ST為轉(zhuǎn)換啟動(dòng)信號(hào)。當(dāng)ST上跳沿時(shí)，所有內(nèi)部寄存器清零；下跳沿時(shí)，開始進(jìn)行A/D轉(zhuǎn)換；在轉(zhuǎn)換期間，ST應(yīng)保持低電平。EOC為轉(zhuǎn)換結(jié)束信號(hào)。當(dāng)EOC為高電平時(shí)，表明轉(zhuǎn)換結(jié)束；否則，表明正在進(jìn)行A/D轉(zhuǎn)換。OE為輸出允許信號(hào)，用于控制三條輸出鎖存器向單片機(jī)輸出轉(zhuǎn)換得到的數(shù)據(jù)。OE1，輸出轉(zhuǎn)換得到的數(shù)據(jù)；OE0，輸出數(shù)據(jù)線呈高阻狀態(tài)。D7D0為數(shù)字量輸出線。 CLK為時(shí)鐘輸入信號(hào)線。因ADC0809的內(nèi)部沒有時(shí)鐘電路，所需時(shí)鐘信號(hào)必須由外界提供，

5、通常使用頻率為500KHZ， VREF（），VREF（）為參考電壓輸入。 (2)、ADC0809應(yīng)用說明 ADC0809內(nèi)部帶有輸出鎖存器，可以與AT89S51單片機(jī)直接相連，初始化時(shí)，使ST和OE信號(hào)全為低電平，送要轉(zhuǎn)換的哪一通道的地址到A，B，C端口上，在ST端給出一個(gè)至少有100ns寬的正脈沖信號(hào)，是否轉(zhuǎn)換完畢，我們根據(jù)EOC信號(hào)來判斷，當(dāng)EOC變?yōu)楦唠娖綍r(shí)，這時(shí)給OE為高電平，轉(zhuǎn)換的數(shù)據(jù)就輸出給單片機(jī)了。 2、SST89E58RD(1)、SST89E58RD管腳圖：3、1602液晶引腳功能說明第1腳：VSS為電源地，接GND。 第2腳：VDD接5V正電源。 第3腳：VL為液晶顯示器對(duì)比

10、數(shù)字量）這樣使得計(jì)算出來的數(shù)值為整型，避免了浮點(diǎn)數(shù)計(jì)算復(fù)雜的缺點(diǎn)，在之后的顯示中加入小數(shù)點(diǎn)即可。子程序設(shè)計(jì)：由于C語言的子程序功能比較強(qiáng)大，所以本程序調(diào)用相關(guān)子程序，減少了很多編程的繁瑣，相關(guān)子程序功能如下所示：函數(shù)功能:400ms延時(shí)延時(shí) 函數(shù)功能:5ms延時(shí) 函數(shù)功能:1602A按指定位置顯示一個(gè)字符函數(shù)功能:1602A初始化 函數(shù)功能:1602A讀狀態(tài) 函數(shù)功能:1602A寫指令函數(shù)功能:1602A讀數(shù)據(jù) 函數(shù)功能:1602A寫數(shù)據(jù) 作用：AD0809通道選擇采樣值流程圖：初始化液晶初始化ADC0809顯示第i路電壓For i=0;i<5;i+顯示W(wǎng)arning同時(shí)蜂鳴器響、紅燈亮
