【Abstract】 Considering low cost and high performance, we realized a kind of data collection card which is used for testing construc-tion material. The card based on PCI bus, has 8 analog input channels, which can be configurated different amplifying coefficients.Also, the card has several key characteristics, such as compact structure, high reliability and stability, all which makes it got exten-sive applications in mass production.更多还原
