Abstract (en)
[origin: EP3992458A1] The present application provides a pressure protection circuit, a control method, and a computer-readable storage medium. The pressure protection circuit comprises: a driving module electrically connected to a compressor; a pressure switch module disposed between the driving module and a power supply loop of the compressor and used for outputting a switching signal, the switching signal being used for controlling the connection or disconnection of the power supply and the driving module; and a control module electrically connected to the driving module and the pressure switch module, and used for inputting a driving control signal to the driving module, so that the driving module controls the compressor to operate according to the driving control signal. The control module is further used for controlling, upon detecting that the switch signal does not match a bus signal of the driving module, the compressor to stop operating. By means of the technical solution of the present application, the compressor is prevented from operating under a working condition in which the pressure switch module fails, the probability of abnormal operation is reduced, and thus the operational safety and reliability of the compressor can be improved.
