Power management system and method

Abstract

A power management system is mainly used for controlling power of a battery-powered electronic device. The electronic device is provided with a plurality of electric parts inside. A detection module detects running states of the electronic parts and produces detection data; an analysis module analyzes the detection data so as to obtain processing commands corresponding to the running states of the electronic parts; finally, a processing module successively control the electronic device to sequentially enter power control modes such as low power, sleep power and power off according to the processing commands. In addition, the invention further provides a power management method. The power of the electronic parts being idle is gradually controlled or shut off by detecting and analyzing the running states of the electronic parts, so that power supply control and power saving are achieved.

Description

[0001] technical field [0002] The present invention relates to a power management system and method, more precisely, to a power management system and method for sequentially regulating the power of electronic components according to the execution status of the electronic components. Background technique [0003] With the vigorous development of computer technology, electronic devices such as computers, notebook computers, tablet computers, and smart phones are becoming more and more popular. Among them, portable electronic devices are small in size and easy to carry, so that everyone can see a mobile phone everywhere, which also shows that Portable electronic devices have penetrated into people's daily life. [0004] Due to the increase in functional requirements, manufacturers continue to innovate portable electronic devices. However, adding new functions also leads to increased power consumption. For example, adding new functions may require adding new integrated circuit...

Problems solved by technology

Therefore, most current electronic devices provide a standby function. Usually, when the electronic device has not been used for a preset value, the system will directly enter the standby stage. Although this will reduce power consumption, the electronic device will not It still consumes power continuously, which not only cannot reduce power consumption immediately, but also cannot maximize power supply
