A predictive control system and regulatory method for a temperature of a livestock house are provided. The predictive control system includes a temperature and humidity sensor, a breeding environment temperature dynamic requirement module, an environmental controller and an environmental regulation implementation mechanism, where the environmental controller is connected to the breeding environment temperature dynamic requirement module and the temperature and humidity sensor; the environmental regulation implementation mechanism is connected to the environmental controller and is configured to perform corresponding environmental regulation according to a command from the environmental controller. The regulatory method controls a temperature of a breeding environment based on a livestock breeding environment temperature dynamic setting model, a livestock breeding environment temperature prediction system based on a GM (1,1) model, and a grey predictive fuzzy system based on the GM (1,1) model.

Predictive control system and regulatory method for temperature of livestock house

The present application discloses a screen projecting method, an apparatus, a device and a storage medium. A specific implementation is: receiving a request for screen projecting from a terminal device, where the request for screen projecting includes indication information of content to be screen-projected; acquiring the content to be screen-projected according to the request for screen projecting; receiving a first initiating message of at least one screen projecting source from a target projecting device, and determining a target screen projecting source from the at least one screen projecting source; and sending the content to be screen-projected and an identifier of the target screen projecting source to the target projecting device, where the identifier of the target screen projecting source indicates to the target projecting device to display the content to be screen-projected through the target screen projecting source.
