The existing shearing machine detection system mostly adopts the master/slave design mode, which involves many parameters to be detected, a large amount of data, and a complicated detection process, and it requires simultaneous acquisition of video signals and physical signals. Moreover, the system has data loss and video distortion, and the data collection speed becomes slower over time. To solve the above problems, a LabVIEW producer/consumer design mode improvement scheme was proposed. The physical signal and the video signal were separately collected, and the data acquisition and data analysis were respectively performed in two cycles, and the two loops were connected by means of a queue to realize an effective combination of each cycle. It has been verified by experiments that the improved design greatly improves the data acquisition and analysis speed, reduces the coupling between the signals, and is obviously effective in avoiding data loss and distortion. So it is worthy of application and promotion in various inspection systems of the mechanical, electrical, energy and other industries.
