In view of the difficulty of on-line monitoring and the fault detection is not accurate., an experimental platform simulating elevator wire rope operation was built. By designing the structure of exciter and detector, a multi-channel data acquisition system for elevator wire rope status monitoring based on LabVIEW was completed. The common fault signals such as wire breakage and wear of wire rope are collected through multiple channels, the waveforms are displayed in real time, and the data are stored for further analysis.The test shows that the system can collect the magnetic flux leakage signal of the wire rope through multiple channels, improve the spatial resolution of the signal, accurately detect fault signals of different degrees of wire rope breakage and wear, and the collected data is saved in the form of TDMS file for waveform playback, so as to further analyze the fault location and degree quantitatively.
