一、電子衡器的工作原理

1、原理圖

Fx → 傳感(gan)器 → OP放大 → A/D轉(zhuan)換 → CPU → 顯(xian)示驅(qu)動

2、工作流程說明

當(dang)物體放(fang)在秤盤上時，壓(ya)(ya)力施給傳感器，該(gai)傳感器發(fa)(fa)生(sheng)(sheng)形變，從而使阻(zu)抗發(fa)(fa)生(sheng)(sheng)變化，同時輸(shu)(shu)出(chu)(chu)電壓(ya)(ya)發(fa)(fa)生(sheng)(sheng)變化，輸(shu)(shu)出(chu)(chu)一個變化的模擬信(xin)(xin)號。該(gai)信(xin)(xin)號經(jing)放(fang)大(da)電路放(fang)大(da)輸(shu)(shu)出(chu)(chu)到(dao)模數(shu)轉(zhuan)換器。轉(zhuan)換成便于處理的數(shu)字信(xin)(xin)號輸(shu)(shu)出(chu)(chu)到(dao)CPU運算控制。CPU根(gen)據鍵盤命令以及程序將這種結(jie)果輸(shu)(shu)出(chu)(chu)到(dao)顯示器。直至(zhi)顯示這種結(jie)果。
