一、電子衡器的工作原理

1、原理圖

Fx → 傳(chuan)感器 → OP放大 → A/D轉(zhuan)換(huan) → CPU → 顯示(shi)驅(qu)動

2、工作流程說明

當物體放在秤盤(pan)(pan)上時，壓力施給傳(chuan)感器(qi)，該(gai)(gai)傳(chuan)感器(qi)發生(sheng)(sheng)形(xing)變(bian)(bian)，從而(er)使阻抗發生(sheng)(sheng)變(bian)(bian)化，同時輸(shu)出(chu)(chu)電壓發生(sheng)(sheng)變(bian)(bian)化，輸(shu)出(chu)(chu)一個變(bian)(bian)化的(de)模擬信(xin)號(hao)。該(gai)(gai)信(xin)號(hao)經放大電路(lu)放大輸(shu)出(chu)(chu)到(dao)模數(shu)轉換器(qi)。轉換成便于處理(li)的(de)數(shu)字(zi)信(xin)號(hao)輸(shu)出(chu)(chu)到(dao)CPU運算(suan)控制(zhi)。CPU根據鍵盤(pan)(pan)命(ming)令以(yi)及程序將這(zhe)種結(jie)果(guo)輸(shu)出(chu)(chu)到(dao)顯示(shi)器(qi)。直至顯示(shi)這(zhe)種結(jie)果(guo)。
