一、電子衡器的工作原理

1、原理圖

Fx → 傳感器 → OP放(fang)大 → A/D轉(zhuan)換 → CPU → 顯(xian)示(shi)驅動

2、工作流程說明

當物體放(fang)(fang)在(zai)秤(cheng)盤(pan)上(shang)時，壓(ya)力施給(gei)傳感器(qi)，該傳感器(qi)發生(sheng)形(xing)變(bian)，從(cong)而使阻抗發生(sheng)變(bian)化，同(tong)時輸(shu)出電壓(ya)發生(sheng)變(bian)化，輸(shu)出一(yi)個變(bian)化的模擬信(xin)號。該信(xin)號經放(fang)(fang)大(da)電路(lu)放(fang)(fang)大(da)輸(shu)出到模數轉換(huan)器(qi)。轉換(huan)成便于處理的數字信(xin)號輸(shu)出到CPU運(yun)算控制。CPU根據鍵盤(pan)命令(ling)以及程序將這種結果輸(shu)出到顯示(shi)器(qi)。直至(zhi)顯示(shi)這種結果。
