一、電子衡器的工作原理

1、原理圖

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

2、工作流程說明

當物體放在(zai)秤(cheng)盤上時(shi)，壓力施給(gei)傳(chuan)感(gan)器，該傳(chuan)感(gan)器發(fa)(fa)生(sheng)形變，從而(er)使阻抗發(fa)(fa)生(sheng)變化，同時(shi)輸出電(dian)壓發(fa)(fa)生(sheng)變化，輸出一(yi)個變化的模擬信(xin)號。該信(xin)號經放大(da)(da)電(dian)路放大(da)(da)輸出到(dao)模數轉(zhuan)換器。轉(zhuan)換成便于處(chu)理(li)的數字信(xin)號輸出到(dao)CPU運算控制。CPU根(gen)據(ju)鍵(jian)盤命令以及(ji)程(cheng)序將(jiang)這種結果(guo)輸出到(dao)顯示器。直至顯示這種結果(guo)。
