Embodiment Construction

[0030] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0031] see Figure 1 to Figure 3 , this embodiment provides a method for delaying power-off and saving power consumption, which is applied to saving power consumption of electronic equipment. Before the processing unit enters the low power consumption mode, the processing unit must receive an instruction to enter the low power consumption mode. The instruction can be realized by the user clicking the low power consumption function button, or the processing unit can automatically trigger after detecting that the current state satisfies a certain condition. , if the battery power is lower than a certain value, it will be triggered. When entering the low power consumption mode, the present invention includes the following steps: Step S1...

Abstract

The invention discloses a method and a device for delaying power failure and reducing power consumption. The method comprises the following steps: a processing unit sends a power consumption saving command to an external power consumption control unit; the processing unit controls the processing unit to enter a low-power-consumption mode after sending the power-consumption-saving command; the power consumption control unit delays for a preset time after receiving the power consumption saving command, and controls the power consumption module connected with the processing unit to enter a power consumption saving state. According to the invention, through the independently arranged external power consumption control unit, after the processing unit enters the low power consumption mode, the external power consumption control unit can independently complete power consumption control on the power consumption module, so that the power consumption is further reduced.

Description

technical field [0001] The invention relates to the technical field of power saving, in particular to a method and device for delaying power-off and saving power. Background technique [0002] In order to save power consumption, existing processing chips or processors have low power consumption modes or standby modules, which save power consumption by turning off power consumption modules connected to themselves. This way of saving power consumption requires the control of the processing chip, and it is necessary to ensure the normal operation of the processing chip. The power consumption module that supports the normal operation of the processing chip cannot be turned off, otherwise it will cause an abnormality of the processing chip. In this way, there is still a situation where a part of the power consumption cannot be further reduced. Contents of the invention [0003] Therefore, it is necessary to provide a method and device for delaying power-off and saving power co...
