Problems solved by technology
The existing technology mainly adopts the method of turning off the relevant system power of the hardware to reduce the power consumption. Although the purpose of reducing the power consumption of the smart device can be achieved, it ignores the power consumption that may be caused by the software application in the smart device.
The software in the smart device often has a timer wake-up function, which will repeatedly switch the power supply of the module, increasing the standby power consumption of the smart device

Embodiment Construction
[0032] The present invention can further reduce standby power consumption, prolong the standby time and increase the use time of the intelligent equipment in the standby state of the intelligent equipment.
[0033] refer to figure 1 As shown, the preferred embodiment of the present invention provides a method for reducing the standby power consumption of smart devices, including:
[0034] Query and record all application events in standby mode;
[0035] Filter out all standby wake-up events in the application event;
[0036] Detecting the time interval of the wake-up event and the size of the fixed threshold;
[0037] Identify wake-up events with an interval greater than or equal to a fixed threshold;
[0038] Write the corresponding wake-up event identified to the hardware.
[0039] When the smart device is in the standby state, the application for any event is carried out through the event generator, and each application event has a corresponding event flag bit, so all a...

The invention discloses a method and a system for reducing standby power consumption of intelligent equipment. The method comprises the following steps of querying and recording all application events in a standby state; filtering all standby wake events from the application events; detecting the time interval of the wake events and the size of a fixed valve value; recognizing the wake event of which the time interval is greater than or equal to the fixed valve value; finally, writing the recognized corresponding wake events into hardware. The system comprises an event module, a filter module, a detection module, a recognition module, a kernel recording module, a hardware judgment module and a write-in module. According to the method and the system disclosed by the invention, by distinguishing the wake events in the intelligent equipment, abnormal wake events are eliminated, so that the power consumption of the intelligent equipment is reduced and the service time of the intelligent equipment is prolonged.
Description
technical field [0001] The invention relates to the field of smart devices, in particular to a method and system for reducing standby power consumption of smart devices. Background technique [0002] At present, the application of smart portable devices such as smart phones and computers has become very popular, and reducing the standby power consumption of smart devices and increasing the use time of smart devices is an important aspect to improve user experience and meet user needs. The existing technology mainly adopts the method of turning off the related system power of the hardware to reduce the power consumption. Although the purpose of reducing the power consumption of the smart device can be achieved, the power consumption that may be caused by the software application in the smart device is ignored. The software in the smart device often has a timer wake-up function, which will repeatedly switch the power supply of the module, increasing the standby power consumpti...
