8 Channel Signal Acquisition Based On Labview Development And Implementation

Virtual instrument is based on computer related hardware and software by increasing the building made with a visual interface of the instrument, which combines the test theory, theory and technology equipment, computer interface technology, high-speed bus technology and graphics software programming technology is equal to one, the use of powerful digital computer processing power to achieve the instrument’s many features, breaking the traditional instruments of the framework, the formation of a new instrument model.This paper describes the measurement and control technology and virtual instrument technology status and future development trend of related technology of virtual instrument, LabVIEW related knowledge, and then expounded on the theory of data acquisition, data acquisition system is given and the hardware block diagram structure. In the analysis of the design features, based on the procedures introduced modular design, database-related knowledge, LabVIEW multithreading technology, given the design front panel and block diagram.This design uses a virtual ART-USB2831data acquisition card, the use of virtual instruments and related technology to achieve a multi-channel data acquisition. The system has multi-channel acquisition, display, storage management and password protection.
