The system for monitoring the electrical operation of the thermal power plant according to claim 7, wherein the first result obtaining module obtains characteristic information of a state to be verified of the electrical device before the electrical device performs the operation, and determines whether a state of the electrical device meets a state requirement before the electrical device performs the operation based on the characteristic information of the state to be verified before the operation is performed, and the step of obtaining the state verification result of the electrical device before the electrical operation includes:
acquiring a characteristic image of a state to be checked before the electrical equipment executes operation;
extracting and obtaining the characteristic information of the state to be verified before the execution operation based on the characteristic image of the state to be verified before the execution operation;
performing similarity matching on the state characteristic information to be verified before the operation is executed and the standard state characteristic information of the same type of standard equipment of the electrical equipment in a pre-operation state in a pre-acquisition standard library to obtain a state similarity index before the operation;
and judging whether the state of the electrical equipment to be operated meets the state requirement before operation or not based on the state similarity index before operation.
9. The system for monitoring the electrical operation of the thermal power plant according to claim 7, wherein the second result obtaining module obtains feature information of a to-be-verified state of the electrical device after the electrical device performs the operation, determines whether a state of the electrical device meets a state requirement after the operation based on the feature information of the to-be-verified state after the operation is performed, and the step of obtaining the state verification result of the electrical device after the electrical operation includes:
acquiring a to-be-verified state characteristic image after the electrical equipment executes operation;
extracting and obtaining the characteristic information of the state to be verified after the operation is executed based on the characteristic image of the state to be verified after the operation is executed;
performing similarity matching on the to-be-verified state characteristic information after the operation is executed and standard state characteristic information of the same type of standard equipment in a pre-acquired standard library in the post-operation state to obtain a post-operation state similarity index;
and judging whether the state of the electrical equipment after the operation meets the state requirement after the operation or not based on the state similarity index after the operation.
