All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a temperature control method, a temperature control device, temperature control equipment and a temperature control medium, which can avoid the phenomenon of blocking during temperature control of terminal equipment and improve the use feeling of a user.
Example 1:

s101: and determining the total power to be distributed of the terminal equipment according to the first temperature acquired in the current period, the preset target temperature and the second temperature acquired in the previous period.
The temperature control method provided by the embodiment of the invention is applied to terminal equipment, such as mobile phones, tablet computers, PCs and other equipment which can be heated.
In order to adjust the temperature of the terminal device in time, in the embodiment of the present invention, the terminal device periodically collects the temperature of the terminal device. The acquisition period for acquiring the temperature of the terminal device may be preset, where the sampling period is generally a short time interval, generally on the order of milliseconds, and may be any value from 500ms to 1s, for example. In addition, in the embodiment of the present invention, a temperature curve of the terminal device may be drawn according to the temperature of the terminal device acquired in each acquisition cycle.
In the embodiment of the present invention, since the heat generation amount of the terminal device is positively correlated with the power at which the terminal device is currently operating, that is, the higher the power at which the terminal device is operating, the larger the heat generation amount of the terminal device is. Therefore, when the terminal equipment is subjected to temperature control, namely the heating value of the terminal equipment is controlled, the total power of the terminal equipment can be controlled.
When the terminal device is temperature controlled, the total power to be allocated to the terminal device may be calculated. The total power to be allocated to the terminal device can be determined according to the first temperature acquired in the current period, the preset target temperature and the second temperature acquired in the previous period of the current period.
S102: and determining the sub power to be distributed corresponding to each subsystem according to the total power and the preset weight of each subsystem of the terminal equipment.
In the embodiment of the present invention, the terminal device is composed of a plurality of subsystems, and specifically, mainly includes a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), and a modem (modem). The heat generated by the operation of the terminal equipment is mainly generated by the three subsystems, so that the operating power of the three subsystems is mainly controlled when the temperature of the terminal equipment is controlled.
In the embodiment of the present invention, the sub-power to be allocated corresponding to each subsystem may be determined according to the preset weight of each subsystem and the total power to be allocated.
S103: and adjusting the working frequency of each subsystem according to the sub-power to be distributed corresponding to each subsystem.
In the embodiment of the present invention, the sub-power calculation formula of each subsystem of the terminal device is: P-cfV2Wherein, P is the sub-power of the subsystem, f is the working frequency of the subsystem, V is the voltage, and c is a constant. As can be seen from the above equation, the sub-power P can be expressed as a function of the operating frequency f, i.e., P ═ f (f), i.e., there is a correspondence between the sub-power P and the operating frequency f. For the terminal device, the operation frequency of the control subsystem is easier to operate than the sub-power for controlling the subsystem to operate, so in the embodiment of the present invention, when the subsystem of the terminal device is controlled, the upper limit of the operating frequency of the subsystem may be determined based on the sub-power to be allocated corresponding to the subsystem, and then the operating frequency of the subsystem is adjusted.
Therefore, in the embodiment of the present invention, after calculating the sub-power to be allocated corresponding to each sub-system of the terminal device, the terminal device may adjust the operating frequency of the sub-system according to the sub-power to be allocated.
