摘要：The conductive slip ring is very useful in the industry equipments, which is an electric assembly being responsible for transporting energy and signals to the rotary body. In order to the conductive slip ring is sealing completely, it’s hard to detect that if its internal wires are conductive. The traditional manual detection is hard to finish that work when the number of the wires is big, and a real-time detection when the equipment is rotated is impossible. This paper uses NI's LabVIEW graphical programming software and DAQ board to realize an automatic detection system for the internal wires of slip ring, which can help us to judge if the wires are conductive when the equipment is rotated in real-time. At the same time, in this paper the application of LabVIEW in data acquisition is also studied.
