The present invention provides a drive interface system for a single-coil relay that supports both main and standby drives, so that two mutually redundant safety drive units can drive the single-coil relay through the drive interface system, including a drive interface module; a drive interface module The input end of the main safety drive unit and the output end of the backup safety drive unit are connected to the output end of the drive interface module, and the output end of the drive interface module is connected to the single-coil relay. The main safety drive unit and the backup safety drive unit are redundant with each other; the drive interface module includes mandatory guidance Relay, one group of outputs of the main safety drive unit is connected to the coil of the forced guide relay, the other group of outputs is connected to the normally open contact of the forced guide relay, and the output of the backup safety drive unit is connected to the normally closed contact of the forced guide relay; in the forced guide The output terminal of the relay connects the normally open contact and the normally closed contact in parallel to the single coil relay. This system makes the self-checks of the main and backup safety drive units not affect each other.

The present application proposes an output control method, device and electronic device. After detecting that the working state of the electronic device satisfies the first condition, the display screen of the electronic device is controlled to work in a sensitive mode. The parameter change information corresponding to each of the multiple sensitive detection areas of the device can more reliably and accurately generate a state adjustment event for the display screen, so as to respond to the state adjustment event and realize the adjustment of the output state of the display screen. Compared with the prior art, only Using a distance sensor deployed under the screen to detect the distance between the user's face and the display screen, the present application can more reliably and accurately determine the distance between the user's body part and the display screen, and can satisfy the user's display of electronic equipment. The application requirements of the screen are improved, and the user experience is improved.
