Problems solved by technology
The power switch can be divided into hard switch and soft switch. The realization of hard switch is generally to turn on and off the power with a mechanical switch. This method can completely cut off the power when the product is not in use for a long time, saving power consumption. It is not very convenient, and adding a mechanical toggle switch will affect the tightness of the product mechanism, and it will also make the electrostatic discharge effect not good
The soft switch is controlled by software to turn on and off the power supply, which can save mechanical switches. It consumes power normally during full-speed operation. When it is not operated for a long time, it enters the power-saving mode through program control, and only turns off the main power-consuming modules. But at this time The program is still running, and there will be a small amount of power consumption; it is not a complete power failure, which cannot reduce power consumption very well

The invention discloses power source managing method of portable electric product, the cell provides operating power for system via a power supply voltage-stabilizing module with enable end, at the same time, a press switch is set at the output end of the power supplying cell, at the two state of running normally and closing, by detecting the press switch action signal and starting and closing information to make the enable end of the power supply voltage-stabilizing module in effective or ineffective state, the operating voltage output end of the power supply voltage-stabilizing module makescorresponding response according to the effective or ineffective state. The invention can fully realize the electricity-cutting off to save energy, and it is easy, the operation is convenient.
Description
technical field [0001] The invention relates to a power management method, in particular to a power management method for portable electronic products; in addition, the invention also relates to a device for realizing the above method. Background technique [0002] In the existing portable electronic products, one method for managing the power consumption of the lithium battery is to supply the power all the time without interruption. For portable electronic products with good performance, the requirements for power consumption are very strict, so there are many power management methods, and the switch control of the power supply is a part of power management. The power switch can be divided into hard switch and soft switch. The realization of hard switch is generally to turn on and off the power with a mechanical switch. This method can completely cut off the power when the product is not in use for a long time, saving power consumption. It is not very convenient, and addi...
