The following describes an intelligent device and a power consumption management method thereof according to an embodiment of the present invention with reference to the drawings.
Fig. 1 is a flowchart of a power consumption management method of an intelligent device according to an embodiment of the present invention. As shown in fig. 1, the power consumption management method of the smart device includes the following steps:
and S101, acquiring the overall power consumption, the main control module power consumption and the main control chip temperature of the intelligent equipment.
In the present application, a power consumption management system of an intelligent device may be first constructed as shown in fig. 2, the intelligent device includes a main control module, the main control module includes a main control chip, the main control chip has a plurality of CPU cores and is internally provided with a temperature sensor, the main control module further includes a current adjusting circuit, a sampling resistor, a voltage dividing resistor and a power management circuit, wherein the current adjusting circuit and the sampling resistor constitute a current collecting circuit for collecting a supply current input to the main control chip; the voltage dividing resistor is used for dividing the voltage input by the external power supply, for example, the input voltage of 5V can be converted into 2.5V; the power management circuit is used for providing voltages of different levels of the main control chip, and particularly, the main control chip and the power management circuit are communicated through a communication interface IIC so as to adjust the power supply voltage input to the CPU core by the power management circuit through the interface.
Specifically, as shown in fig. 2, when performing power consumption management on the intelligent device, according to the power consumption management system set up above, the overall power consumption of the intelligent device is calculated by an alternate acquisition metering circuit (not shown in the figure) in the intelligent device, and is input to the main control chip through a Serial Peripheral Interface (SPI) or a Universal Asynchronous Receiver Transmitter (UART); the main control chip can respectively acquire the power supply voltage and the power supply current input into the main control chip according to a 2-path analog-digital converter interface (not shown in the figure) so as to calculate the power consumption of the main control module; the main control chip can also acquire the temperature of the main control chip in real time through a built-in temperature sensor so as to acquire the temperature of the main control chip.
Step S102, determining that at least one parameter of the overall power consumption, the power consumption of the main control module and the temperature of the main control chip meets a corresponding first preset condition, and performing power consumption reduction adjustment on the main control module.
Specifically, after the complete machine power consumption, the main control module power consumption and the main control chip temperature of the intelligent device are obtained, if at least one parameter of the complete machine power consumption, the main control module power consumption and the main control chip temperature meets a corresponding first preset condition, the main control module is subjected to power reduction adjustment, namely, if one parameter of the complete machine power consumption, the main control module power consumption and the main control chip temperature meets the first preset condition, the main control module is subjected to power reduction adjustment, so that the power reduction adjustment of the main control module is realized.
In some embodiments, at least one parameter of the overall power consumption, the power consumption of the main control module and the temperature of the main control chip satisfies a corresponding first preset condition, which includes: the power consumption of the whole machine is larger than the first preset power consumption, or the power consumption of the main control module is larger than the second preset power consumption, or the temperature of the main control chip is larger than the preset temperature.
Further, the power consumption reduction adjustment is performed on the main control module, and the power consumption reduction adjustment comprises the following steps: and at least one of the main frequency of the main control chip, the power supply voltage of the CPU core and the core number of the CPU core is reduced.
Specifically, a first preset power consumption Pzw, a second preset power consumption Pcw and a preset temperature Tw are preset in the main control module, the obtained whole power consumption Pz, the obtained main control module power consumption Pc and the obtained main control chip temperature T are respectively compared with the first preset power consumption Pzw, the second preset power consumption Pcw and the preset temperature Tw, whether the whole power consumption Pz is larger than the first preset power consumption Pzw, whether the main control module power consumption Pc is larger than the second preset power consumption Pcw, and whether the main control chip temperature T is larger than the preset temperature Tw are compared, if the whole power consumption Pz is larger than the first preset power consumption Pzw, or the main control module power consumption Pc is larger than the second preset power consumption Pcw, or the main control chip temperature T is larger than the preset temperature Tw, it is indicated that the main control module has high power consumption, and power consumption reduction adjustment needs to be performed on the main control module. The power consumption of the main control module is mainly related to the main frequency of the main control chip, the power supply voltage of the CPU core and the core number of the CPU core, so that when the power consumption of the main control module is reduced, only one parameter can be reduced to reduce the power consumption of the main control module, for example, only the main frequency of the main control chip is reduced, and a plurality of parameters can also be reduced to improve the power consumption reduction degree of the main control module, for example, the main frequency of the main control chip, the power supply voltage of the CPU core and the core number of the CPU core are reduced simultaneously.
Therefore, the power consumption of the main control chip is dynamically adjusted based on the power consumption of the whole machine, the power consumption of the main control module and the temperature of the main control chip, the dynamic consumption reduction adjustment of the main control chip is realized under the condition that the power consumption requirement and the temperature limit of the intelligent device are met, and the difficulty of the power consumption adjustment of the intelligent device chip is reduced.
In some embodiments, when determining that one parameter of the overall power consumption, the power consumption of the main control module and the temperature of the main control chip satisfies a corresponding first preset condition, performing power consumption reduction adjustment on the main control module includes: determining the interval of the parameters; acquiring a maximum value of the dominant frequency, a maximum value of the power supply voltage of the CPU core and a maximum value of the core number of the CPU core according to the intervals, wherein a plurality of intervals are preset, and each interval is provided with the maximum value of the dominant frequency, the maximum value of the power supply voltage of the CPU core and the maximum value of the core number of the CPU core; and reducing the dominant frequency of the main control chip, the power supply voltage of the CPU core and the core number of the CPU core so as to enable the dominant frequency to be less than or equal to the maximum value of the dominant frequency, the power supply voltage of the CPU core to be less than or equal to the maximum value of the power supply voltage of the CPU core and the core number of the CPU core to be less than or equal to the maximum value of the core number of the CPU core.
Specifically, when determining that one parameter among the overall power consumption, the power consumption of the main control module and the temperature of the main control chip meets a corresponding first preset condition, that is, when determining that the overall power consumption Pz is greater than a first preset power consumption Pzw, or the power consumption Pc of the main control module is greater than a second preset power consumption Pcw, or the temperature T of the main control chip is greater than a preset temperature Tw, the power consumption reduction adjustment is performed on the main control module according to the determined parameter (the overall power consumption Pz, the power consumption Pc of the main control module, or the temperature T of the main control chip).

It should be noted that, this is only a partial example, and other combination situations also exist, for example, the overall power consumption Pz is greater than the first preset power consumption Pzw, the power consumption Pc of the main control module is greater than the second preset power consumption Pcw, the overall power consumption Pz is greater than the first preset power consumption Pzw, the temperature T of the main control chip is greater than the preset temperature Tw, the power consumption Pc of the main control module is greater than the second preset power consumption Pcw, and the temperature T of the main control chip is greater than the preset temperature Tw, and the like.

That is, after the power consumption of the main control module is reduced, if it is determined that the power consumption of the entire main control module is less than or equal to the first preset power consumption, the power consumption of the main control module is less than or equal to the second preset power consumption, and the temperature of the main control chip is less than or equal to the preset temperature, it is described that the power consumption of the main control module has been reduced to a safe range, in order to exert the performance of the main control chip to the maximum extent, the operating speed of the main control chip may be increased by increasing at least one of the main frequency of the main control chip, the power supply voltage of the CPU core, and the core number of the CPU core, so as to achieve dynamic balance between the power consumption and the performance.
