Design of the Signal Detection System Based on the LabVIEW

A set of test platform used in signal detection system is designed,its hardware and software model are introduced,and the test program block diagram and display interface are also given.The system hardware consists of analog signal adjusting modules,digital signal photoelectric isolation modules and data acquisition boards.System software using LabVIEW programming technology realizes signal sampling,processing,display and storage,and the way to read and write OLE field of Access database in the LabVIEW environment is introduced.This system is proved to be stable and minor error,and fully meets the functional requirements of the test platform.
