    基于ADS1232的高精度測試技術

    2008-06-19

    摘  要:為解決傳統的高精度A/D測量電路中需要在A/D前端搭建多級放大器而帶來的成本及檢測過程中的漂移問題,采用24 位超低噪聲模數轉換器 ADS1232,并在設計過程中使用了多種單片機抗干擾措施,設計出來的高精度測試儀器在硬件和軟件上都得到了簡化,該系統可以得到一個可靠的高精度的測量結果,解決了橋接傳感器的前端問題。實踐表明,該系統工作穩定,性能良好。   關鍵詞:ADS1232轉換器;橋式傳感器;高精度;測試;抗干擾   中圖分類號:TP274;TP319        文獻標識碼:A          文章編號:1672-4984(2008)03-0138-03   High-precision testing technology based on ADS1232   JIANG Ling-bin1, LIU Si-song1, DANG Zheng-qiang2   (1.College of Nuclear Technology and Automation Engineering,Chengdu University of Technology,Chengdu 610059,China; 2.National Institute of Measurement and Testing Technology,Chengdu 610021,China)   Abstract: In order to overcome the problems including high cost and drift, caused by the multi-stage amplifiers constructed in the front-end of the Analogy-to-Digital(A/D) in the traditional high precision A/D test circuit, a high-precision testing instrument used 24-bit analog-to-digital converter, a low-noise programmable gain amplifier (PGA), ADS1232 and many anti-interaction techniques of Microchip Controller Unit(MCU) were designed. It simplified both in hardware and software, and it could give reliable and high-precision measurement results. Also, it provided complete front-end for bridge sensor applications. All practical results show this system performance well and stably.   Key words: ADS1232; Bridge sensor; High-precision; Test;   Editor:liyan
