【摘要】：針對多路溫度同步測量的需求,研制了一種基于可編程邏輯陣列(field program gate array,FPGA)和低功耗內(nèi)核(STM32)的多路溫度同步測量系統(tǒng)。該系統(tǒng)以FPGA為主控制器,直接驅(qū)動多片模數(shù)轉(zhuǎn)換器件,對多路電信號進行同步測量,使用STM32實現(xiàn)溫度信號的轉(zhuǎn)換和計算。系統(tǒng)預(yù)期測溫范圍為-200~850℃,測溫精度達到0.01℃。實驗結(jié)果表明,該系統(tǒng)在使用PT100溫度傳感器測溫且測溫范圍為-200~400℃時,系統(tǒng)測量誤差小于0.003℃,全量程(-200~850℃)范圍內(nèi)系統(tǒng)測量誤差小于0.005℃。所設(shè)計的多路溫度同步測量系統(tǒng)盡管隨溫度增大測量誤差存在增大趨勢,但在全量程范圍內(nèi)實現(xiàn)了0.01℃測溫精度的目標,并具有多路溫度同步測量、通道數(shù)易于擴展等優(yōu)點,具有一定的實用價值。
