Low-power-consumption digital photo frame system

Abstract

The invention discloses a low-power-consumption digital photo frame system, and relates to the technical field of power consumption management of digital photo frames and consumer electronics. The problem of reducing power consumption of equipment in a shutdown state is solved. The system specifically comprises a user input module, a human body induction module, a clock module, an electronic switch module, a main chip system module and a microcontroller, the user input module comprises onboard keys and a remote controller, the main keys are defined as common keys such as upward, downward, leftward, rightward, confirmation, return and power keys, the power key is used for switching on and off, other keys are used for operating the digital photo frame, and the onboard keys are installed on a machine to facilitate short-distance operation. When the system is shut down, the microcontroller turns off the main power supply, the microcontroller enters the deep sleep state, the power consumption of the microcontroller in the deep sleep state can reach a microampere level or even lower, the shutdown power consumption of a digital photo frame product is greatly reduced, and unnecessary energy waste is reduced.

Description

technical field [0001] The invention relates to the technical field of power consumption management of digital photo frames and consumer electronics products, in particular to a low power consumption digital photo frame system. Background technique [0002] With the development of technology, more and more electronic digital products have entered thousands of households, providing people with a colorful life. At present, some countries have stricter requirements on the power consumption of digital products when they are turned off. The general power consumption test standard is IEC62301:2011, which requires less than 0.5W for standby and shutdown power consumption. The shutdown power consumption of the main control chips of some digital products is generally high due to the process and architecture, and cannot meet IEC62301: In addition, the digital photo frame can be turned on and off through the onboard buttons, remote control, touch screen, etc. in actual use scenarios. ...
