Abstract

The present invention discloses a LabVIEW-based accelerometer signal acquisition device and method. The apparatus comprises a data adjusting terminal and a client, wherein the data adjusting terminal comprises a charge output type accelerometer and a charge amplifier, and the client comprises a charge amplifier control module, a data processing module and an error processing module. According to the method, a VI server is utilized to achieve dynamic call of event response, acquired data are separated, the output is a figure or saved as a file, and errors are processed by using built-in function error detection, operation logic error detection and an error cluster status separation method. The problems that remote data acquisition cannot be performed on accelerometer signals without a data acquisition card and control of the charge amplifier is usually independent of data acquisition and processing functions are solved. The function of acquiring the accelerometer signals without the data acquisition card is fulfilled, the function of controlling the charge amplifier is integrated with the data acquisition and processing functions, and therefore test efficiency and control convenience are improved.
