摘要：

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.　©　2011　IEEE.
