The application of LabVIEW in the strapdown inertial measurement system

In order to improve the testing efficiency and accuracy of the inertial system, a performance test system for the strapdown inertial system which is based on LabVIEW and PCI data acquisition card has been designed. The design includes the hardware design and the software design. The hardware includes the design of analog modulate circuit and 24-channel digital acquisition card. A set of parameters of inertia equipment is sampled by a 16-channel PCI analog acquisition card and a 24-channel PCI digital acquisition card. The LabVIEW 2011 is used to design the software system. The system has the functions of acquisition, processing, analysis and storage and query. During the operation, the functions of system are stable and meet the design requirements.
