一、電子衡器的工作原理

1、原理圖

Fx → 傳感(gan)器 → OP放大 → A/D轉換 → CPU → 顯(xian)示驅動

2、工作流程說明

當(dang)物體放(fang)在秤盤上時(shi)，壓(ya)力施給傳感(gan)器，該(gai)傳感(gan)器發生形變(bian)(bian)，從而使阻抗發生變(bian)(bian)化，同時(shi)輸(shu)(shu)出(chu)電壓(ya)發生變(bian)(bian)化，輸(shu)(shu)出(chu)一個變(bian)(bian)化的模(mo)擬信號。該(gai)信號經放(fang)大電路放(fang)大輸(shu)(shu)出(chu)到模(mo)數(shu)轉換器。轉換成便于處理的數(shu)字信號輸(shu)(shu)出(chu)到CPU運算控制。CPU根據(ju)鍵盤命令以(yi)及程序將這(zhe)種結(jie)果輸(shu)(shu)出(chu)到顯示器。直至顯示這(zhe)種結(jie)果。
