Abstract

The application belongs to the technical field of electronic equipment control, and discloses a projector control method, a projector control device, a projector and a storage medium. The application detects whether wind power is generated at the air outlet of the projector, if so, generates a lens opening signal, and sends the lens opening signal to the lens control motor to control the opening of the lens cover. If wind power is generated at the air outlet of the projector, the projector can be determined to be started or in a working state, and the lens cover is controlled to be opened at the moment, so that the lens cover is prevented from being opened in a non-use state of the projector, dust can be effectively prevented from entering the lens, and foreign objects can be effectively prevented from damaging the lens.
