Fault early warning method and device, storage medium and electronic equipment

The invention relates to the technical field of rail transit fault early warning, and discloses a fault early warning method, which is characterized by comprising the following steps: acquiring operation state data of all target sensors which are sensors of the same kind; performing monitoring and early warning on all the target sensors according to the operation state data through a fault early warning model; wherein the fault early warning model is generated according to the operation state data of a plurality of similar sensors of the target sensor. On the basis of running state data of similar sensors of a train, state data differences between the similar sensors are subjected to statistical analysis, then change characteristics and distribution rules of the differences are extracted, and then a set of sensor abnormity self-checking method is constructed, so that intelligent early warning of sudden faults and gradual faults of similar sensor systems of the train is achieved.
