TRICONEX 3301
當(dāng)K=時(shí),可以得到電壓V的分辨率=0.015K=0.01mV。
這樣就從理論上得到了最后輸出的電壓源的分辨率可以達(dá)到0.01mV,不僅可以滿足系統(tǒng)的0.1mV分辨率要求,還留有充足的余量,使得V的輸出可以通過對(duì)精密數(shù)字電位器以及D/A2的軟件修正來進(jìn)行校準(zhǔn),從而避免由于元器件溫度漂移、D/A轉(zhuǎn)換非線性誤差等對(duì)輸出造成的影響。
產(chǎn)生Vstand的電路如圖2所示,Vstand在圖中是網(wǎng)絡(luò)標(biāo)號(hào)STAND_VOL所代表的信號(hào)。高精度電壓V的?電鍍專用行車采用遠(yuǎn)距離控制,起吊重量500kg以下,起重物品是有待進(jìn)行電鍍或表面處理的各種產(chǎn)品零件。根據(jù)電鍍加工工藝的要求,電鍍專用行車的結(jié)構(gòu)和動(dòng)作流程如圖1所示,其中1槽為電鍍槽,槽中裝有電鍍液,2槽為回收槽,3槽為清水槽,實(shí)際生產(chǎn)中電鍍槽的數(shù)量由電鍍工藝要求決定,電鍍的種類越多,槽的數(shù)量越多。
