Application of Data Acquisition Card of Virtual Instrument Based on PCI Bus in Tilting Train Mesurement

A data acquisition card of virtual instrument based on PCI bus is introduced,which is applied in the testing system of tilting train.The interface chip of S5933 is the pivotal part of the card followed by a special low pass filter.The signal of the acceleration and the orbit excess of the running tilting train can be exactly tested and filtered in time.By the test of the true run,the practicality and superiority of the card is proved.
