Abstract: An outdoor device reset system includes a voltage regulation apparatus coupled to a power supply apparatus and an outdoor device coupled to the voltage regulation apparatus. The voltage regulation apparatus is configured to regulate a working voltage input to the outdoor device based on a feedback signal, a supply voltage from the power supply apparatus for the voltage regulation apparatus, and a reference voltage of the voltage regulation apparatus. The outdoor device is configured to determine a change amount of the working voltage, and perform a reset operation when the change amount is within a preset range.

Abstract: This application provides an outdoor device unit reset system, to resolve a problem in a conventional technology that an outdoor device unit needs to be reset by using a reset switch on the outdoor device unit. The system includes a voltage regulation apparatus connected to a power supply apparatus and an outdoor device unit connected to the voltage regulation apparatus. The voltage regulation apparatus is configured to regulate, based on a detected feedback signal, a supply voltage provided by the power supply apparatus for the voltage regulation apparatus, and a reference voltage of the voltage regulation apparatus, a working voltage input to the outdoor device unit. The outdoor device unit is configured to: determine a change amount of the working voltage input to the outdoor device unit, and perform a reset operation when the change amount is within a preset range.
