Power terminal information attack monitoring method and system

The invention provides a power terminal information attack monitoring method and system, and belongs to the technical field of power system terminals, and the method specifically comprises the steps: extracting the power consumption characteristic quantity of a power terminal in real time, transmitting the power consumption characteristic quantity into a prediction model based on a GA-GRU algorithm, judging whether the state of the power terminal is normal or not at the moment, and if yes, judging whether the state of the power terminal is normal or not; if the state of the power terminal at the moment is in a normal state, continuing to adopt the prediction model to perform state judgment on the power terminal based on the power consumption characteristic quantity of the power terminal extracted in real time, and if the state of the power terminal at the moment is in an abnormal state, continuing to perform classification result judgment based on the communication message; extracting a communication message
