Problems solved by technology

[0006] A major problem in the prior art is that the operating frequency is set according to the current system occupancy of the smart TV CPU because the current system occupancy of the smart TV CPU is periodically counted; however, because the system occupancy of the smart home appliance CPU is constantly changing In this way, the optional operating frequency set according to the current system occupancy of the smart TV CPU cannot match the system occupancy in the future period of the statistical period well, resulting in waste of power consumption (the set operating frequency is greater than the required operating frequency frequency) or insufficient computing performance (the set operating frequency is less than the required operating frequency)

Embodiment 1

[0024] figure 1 It is a schematic flow chart of a CPU frequency conversion method for a smart home appliance provided in this embodiment. For ease of description, only parts related to this embodiment are shown in the figure.

[0025] The frequency conversion method of the smart home appliance CPU provided in this embodiment is applied to the smart home appliance CPU with multiple optional operating frequencies; for example, the optional operating frequency F1, the optional operating frequency F2, ... , optional working frequency F(n-1), optional working frequency Fn, etc.; the CPU frequency conversion method for smart home appliances mainly includes steps:

[0026] Step 1: Predict the future time period system occupancy of the smart home appliance CPU according to the system occupancy of the smart home appliance CPU in the historical period and the system occupancy of the current period. This is because the change trend of the CPU system occupancy of the smart home appliance...

Embodiment 2

[0030] In this embodiment, on the basis of the first embodiment, the CPU frequency conversion method of the smart home appliance provided by the present invention is described in more detail.

[0031] Step 1: Predict the future time period system occupancy of the smart home appliance CPU according to the system occupancy of the smart home appliance CPU in the historical period and the system occupancy of the current period. In this embodiment, the system occupancy in the historical time period, the system occupancy in the current time period, and the system occupancy in the future time period can all be the average value of the total system occupancy in the time period; System occupancy, current time period system occupancy and future time period system occupancy can also be the maximum value of system occupancy in a time period, etc.; and the duration of historical time period, current time period and future time period can also be set according to actual needs, which can be t...

Embodiment 3

[0052] This embodiment provides a smart home appliance; the smart home appliance includes a smart TV CPU with multiple optional operating frequencies, and also includes the smart TV CPU frequency conversion device provided in the above embodiment, so that pre-conversion of the smart home appliance CPU can be realized ; The smart home appliance may be a smart TV, a smart refrigerator, a smart air conditioner, and the like. Since smart TVs need to handle more computing tasks than other smart home appliances mentioned above, the smart home appliance CPU and its frequency conversion device provided in the present invention are especially suitable for smart TVs; the smart TV can be an integrated machine or a Smart TV realized through OTT (Over The Top, refers to the TV transmission mode that does not depend on the intermediate transmission network) set-top box; when the smart TV is an integrated machine, the smart TV CPU and the smart TV CPU frequency conversion device are integrate...

Abstract

The invention provides a frequency conversion method and a frequency conversion device for an intelligent household electrical appliance, and the intelligent household electrical appliance that applies the intelligent household electrical appliance CPU frequency conversion device. The intelligent household electrical appliance CPU frequency conversion method is applied to an intelligent household electrical appliance CPU having various optional working frequencies, and comprises: Step 1: according to system occupation in a historical period and system occupation in the current period of the intelligent household electrical appliance CPU, predicting system occupation of a future period of the intelligent household electrical appliance CPU; and Step 2: according to the system occupation of the future period, selecting a corresponding optical working frequency as the working frequency of the future period, and enabling the intelligent household electrical appliance CPU to work at the working frequency of the future period. The intelligent household electrical appliance CPU frequency conversion method realizes preadjustment of the working frequency of the intelligent household electrical appliance CPU, and the selected optional working frequency can be matched with the system occupation within the future period as much as possible, thereby reducing the occurrence of problems of power dissipation waste or insufficient operation processing performance.

Description
