Abstract:RVDT signal simulation equipment plays an important role in aviation computer design, commissioning and in the calibration of RVDT data acquisition system and so on. Through in-depth analysis theory of RVDT sensors work, the paper proposes RVDT signal simulation method based on PXIe bus. This paper focuses on the RVDT sensors work principle and output characteristics, expounds the design and implementation of RVDT simulation equipment. Finally using the north Atlantic company RVDT DAQ card CPCI-75C3 ,RVDT simulation equipment is verified, and the results show that the equipment is of high precision, fast response speed and stable operation.
