Multi-channel acquisition and data processing based on Labview

This proper uses USB-3202N data acquisition card as the main hardware, and uses Labview as the development software to achieve four-channel data acquisition. The system can realize multi-channel data acquisition and real-time display, storage and other functions, and at the same time for the data obtained three-dimensional map. Compared with the traditional acquisition technology, this design has simple program design and simple interface. It is applied to the well drilling ultrasonic logging Instrument (ULISSD), which can solve the problems encountered in the ultrasonic transducer at the present stage and lay a certain foundation for the upgrade of the next generation.
