Fault Detection Expert System of Elevator Control Cabinet Based on LabView

Abstract

An expert testing system of elevator control cabinet was developed based on LabView, for resolving the difficulties on elevator testing and elevator fault troubleshooting. With fault tree analysis algorithm, manual knowledge obtaining method was used, and forward reasoning strategy was employed for locating the possible reason of the system fault quickly and exactly. The system was modularized to reduce the complexity of the program. The graphical interface was programmed by LabView to improve human-computer interaction ability. The results indicated the expert system can be applied to system fault detection well and improve the efficiency of elevator troubleshooting.
