Four-channel virtual oscilloscope based on Labview

In this paper, a Labview-based four-channel virtual oscilloscope is designed for the use of Ultrasonic logging instrument for shaft sinking by drilling (ULISSD). Firstly, the usage environment is analyzed and explained. Secondly, the functions and software design of the designed four-channel virtual oscilloscope by using the analog to digital conversion acquisition card are introduced and discussed from the research method. Finally, the designed four-channel virtual oscilloscope is tested by a certain environment. Combined with the use of experiments with ULISSD, it is proved that the virtual instrument can realize the detection of four-channel data, which can solve the problems encountered in the use of ultrasonic transducer at the present stage and lay the foundation for the upgrade of the next generation ULISSD.
