Abstract

In industry field, common A/D converter chips are widely used for low-speed analog data acquisition. Most of common A/D converter chips are not fit for the requirements of high-speed vary analog signal. This paper presents a high-speed data acquisition system which interface and algorithm are programmed in Delphi 7.0. The design is based on PCI-1716 card is proposed for LVDT sensor detection and realized the high-speed analogical data acquisition of multichannel sensor analog signals in the method of software polling mode. The measured results of application indicate that the measurement precision can reaches 0.01 mm, and this system has good commonality as well as extensibility.
