the processing module is used for judging whether the difference value between the actual temperature value and the control temperature value is larger than a preset value at a preset moment, if so, an adjusting instruction is sent to the infrared remote control module according to the difference value, and the infrared remote control module is used for calling infrared remote control data in the storage module according to the adjusting instruction so as to send a control signal to an electric appliance;
and the preset time is the time when a preset time length passes after the time when the control signal is sent for the last time.
8. The digital display of claim 7, wherein the adjustment command includes an adjustment amount having a unit adjustment value of a first wind speed, an N wind speed equal to a first temperature, and for a target adjustment amount including a temperature adjustment amount and a wind speed adjustment amount less than the N wind speed, the temperature adjustment amount being greater than or equal to zero,
the processing module is further used for judging whether a control instruction is received or not after the adjustment instruction is sent, judging whether the difference value is increased or not after the electrical appliance is adjusted according to the control instruction if the control instruction is received, increasing the adjustment amount in the next adjustment instruction if the control instruction is increased, and reducing the adjustment amount in the next adjustment instruction if the control instruction is decreased.
9. A digital display is characterized in that the digital display comprises a BLE module, a storage module and a processing module,
the BLE module is used for being connected with a mobile terminal through a Bluetooth signal;
the mobile terminal is used for accessing the server and acquiring an upgrading data packet;
the BLE module is used for receiving the upgrading data packet transmitted by the mobile terminal;
the storage module is used for storing the upgrading data packet;
the processing module is used for upgrading the firmware of the host by using the upgrading data packet;
wherein the storage module comprises a first storage area and a second storage area, the first storage area is used for storing the application program of the host,
the storage module is used for storing the upgrading data packet in the second storage area;
the processing module is used for verifying whether the upgrading data packet of the second storage area is legal or not, deleting the application program in the first storage area if the upgrading data packet of the second storage area is legal, writing the upgrading data packet of the second storage area into the second storage area as the application program, and emptying the second storage area.
10. An upgrade method for upgrading a digital display according to any one of claims 1 to 9.
