基于單片機(jī)的水箱液位監(jiān)測控制系統(tǒng)設(shè)計

1、摘 要液位監(jiān)測系統(tǒng)在很多的地方都會用到，例如在工廠的生產(chǎn)當(dāng)中，液位控制是否得當(dāng)就會影響生產(chǎn)產(chǎn)品的質(zhì)量和美觀，在生活當(dāng)中，我們離不開水的利用，常常需要對水箱或水塔水位的監(jiān)測，液位監(jiān)測系統(tǒng)也與我們的生活息息相關(guān)，它關(guān)系著我們生活的品質(zhì)和效率，所以我們要對液位進(jìn)行連續(xù)的監(jiān)測和控制。本文的設(shè)計的是利用 AT89C51 單片機(jī)實現(xiàn)對水箱液位監(jiān)測，通過分析領(lǐng)域條件下，在其系統(tǒng)中通過液位變送器獲取信息（4-20mA） ，其采集電流太小而不容易測量，

2、所以需要用放大電路對其放大，通過處理后，由模數(shù)轉(zhuǎn)換變換為二進(jìn)制數(shù)傳入單片機(jī)，它可以對數(shù)據(jù)進(jìn)行實時的處理。并在本文的軟件設(shè)計當(dāng)中介紹了本次系統(tǒng)的電路原理圖和軟件編寫時所需的流程圖，然后通過顯示電路把采集到的液位高度值顯示給我們。最后通過 Keil C51 軟件編寫出本次系統(tǒng)所需要的程序，同時在 Proteus 軟件里進(jìn)行仿真，實現(xiàn)了對液位監(jiān)測。通過該設(shè)計的運用，滿足了間接測量，自動的控制及其管理的目的。關(guān)鍵詞：單片機(jī)；液位控制；Prote
