The shearing machine detection system has many parameters to be detected, the data volume is large, the detection process is complicated, and we must acquire video signals and physical signals simultaneously. Therefore, in view of the problems of data loss, video distortion and slow data acquisition speed in the previous system using the master/slave design model, useing the LabVIEW producer/consumer design model to improve the detection system. The physical and video signals are separated into a single detection step, the data acquisition and the data analysis are respectively performed in two cycles, and the two loops are connected by means of a queue, thereby realizing an effective combination of the respective detection steps. The shear test shows that the design greatly improves the data acquisition and analysis rate, reduces the coupling between the signals, and has obvious effects on avoiding data loss and distortion,it is worthy of application and promotion in various inspection systems of the mechanical, electrical, energy and other industries.
