The invention provides a remote real-time monitoring and fault diagnosis system of a mine fan based on an LabVIEW platform. The system comprises hardware of an industrial control computer, a terminal board, a PCI data acquiring card, signal conditioning equipment and a vibration speed sensor, and comprises software of a data acquiring module, a data memory and management module, a data display module, a history inquiring module, a fault diagnosis module and a network distribution module. The system realizes real-time acquisition of fan vibration signals, dynamic monitoring of equipment operation states, the setting, display and warning prompt of equipment operation normal values, warning values and stop range values and the storage and inquiry of such related data as various fault data and diagnosis results, and adopts an analytic hierarchy process algorithm to obtain various fault generation probabilities. A wire communication network is built; and the remote real-time monitoring and diagnosis is realized by using a share variable technology. The system can improve the big data processing capacity, and realizes the local and remote monitoring and fuzzy fault diagnosis of the fan operation states.
