Safety control method and device for air blower

The embodiment of the invention provides a safety control method and device for an air blower, and relates to the technical field of logic control solutions of equipment faults for air blowers and the like. The method comprises the steps that real-time parameters of the air blower are obtained, and the real-time parameters are preprocessed to obtain first parameters; performing graph-to-digital conversion processing on the first parameter to determine the position of the real-time working condition point in a preset energy diagram; determining the working field of the real-time working condition point according to the position of the real-time working condition point in a preset energy diagram; and determining a control strategy according to the working field of the real-time working condition point, and executing the target operation based on the control strategy so as to enable the real-time working condition point to continuously run in a preset safety area. Through the air blower safety control method and
