摘要:
LabVIEW is a graphical programming language that is regarded by industry, academia and research laboratories as a standard data acquisition and instrument control software. In this paper, a data acquisition system of escalator vibration signal is designed, and the functions of collecting, analyzing, storing and replaying vibration data of multi-channel escalator are realized. In addition, field tests were carried out on key parts of the escalator, such as the main engine, the reducer and the steps, to realize the acquisition of vibration data of key parts of the escalator and the analysis of vibration characteristics such as peak acceleration, spectrum characteristics and power spectrum.
