Equipment safety monitoring identification method and device based on maximum region molecular sequence

The invention discloses an equipment safety monitoring identification method and device based on a maximum region molecular sequence. The method comprises the following steps: acquiring an original discrete signal sent by any equipment in a training sample set and a to-be-monitored discrete signal sent by target equipment to be subjected to safety monitoring; performing preset processing on the original discrete signal to obtain a plurality of first subsequences corresponding to each first time sequence included in the plurality of signal categories; performing preset processing on the to-be-monitored discrete signal to obtain a plurality of second subsequences corresponding to each second time sequence included in the plurality of signal categories; obtaining a plurality of first reference subsequences under each same signal category and second reference subsequences under a plurality of different signal categories in the original discrete signals according to the first subsequences and the second subsequenc
