Abnormal state detection method and device of state machine, electronic device and storage medium

The invention relates to an abnormal state detection method and device of a state machine, an electronic device and a storage medium, and the abnormal state detection method of the state machine comprises the steps: obtaining a real-time abnormal state; based on the real-time abnormal state, a corresponding first input signal sequence is obtained in a database, the database stores a corresponding relation between the abnormal state and the input signal sequence, and the input signal sequence comprises signal states of a plurality of input interfaces; and comparing the first input signal sequence with a second input signal sequence in a target state to obtain an abnormal signal position, the abnormal signal position being a position where the first input signal sequence is inconsistent with the second input signal sequence. Through the method and the device, the technical problem of low abnormal state detection efficiency of the state machine in the prior art is solved, and the diagnosis efficiency of the stat
