Abstract

The invention provides an equipment fault diagnosis method and device, a storage medium and equipment. The method comprises the steps of: acquiring fault information of the equipment; performing inference based on the acquired fault information to obtain a fault hypothesis; and verifying the fault hypothesis obtained by inference to obtain a fault diagnosis result. The method and the device can realize automatic diagnosis on equipment faults and can provide a fault solution strategy.

Description

technical field [0001] The invention relates to the field of fault diagnosis, in particular to a device fault diagnosis method, device, storage medium and equipment. Background technique [0002] During the use of electrical equipment such as air conditioners and washing machines, it is an inevitable fact that failures will occur. Overhauling the equipment is a prerequisite to ensure the safe operation of the equipment and the highest performance. The implementation of the most advanced condition-based maintenance system in the world is inseparable from the application of fault diagnosis technology. At present, the fault diagnosis technology for equipment is basically limited to manual inspection on the production line and after sales. For example, detection of remote control receiving device, power-on detection, manual on-site maintenance after failure, etc. Moreover, these diagnostic methods do not involve the comprehensive diagnosis of the entire system of the equipmen...
