Provided are a power control method and a system for an electronic device having a touch screen. The system comprises a microprocessor, a human body sensing component, a battery, and an external power source. The human body sensing component is used to detect a human body approaching the touch screen and send a detection result to the microprocessor. The battery and the external power source supply power to the electronic device having the touch screen under the control of the microprocessor. When the human body sensing component detects that the human body approaches the touch screen, the battery is used to supply power to the electronic device having the touch screen; and when the human body sensing component does not detect that the human body is approaching the touch screen, the external power source is used to supply power to the electronic device having the touch screen. The system does not need to adapt to different grid environments and circuits, and has a strong compatibility. By disconnecting the power supply of the external power grid, the touch screen is powered on by using the internal charging battery, which solves the problem of electromagnetic interference of the power grid.
Description
technical field [0001] The invention relates to the field of smart home appliances, in particular to a power management system and a control method for electronic equipment with a touch screen. Background technique [0002] Touch screen, also known as "touch screen" or "touch panel", is an inductive electronic device that can receive touch signals. When working, the user touches the touch screen on the front of the display with fingers or other objects, and the touch detection component detects the user's touch position on the touch screen, and converts the touch information into contact coordinates and sends it to the processing device. Menu position to locate selection information input. As a computer input device, the touch screen is currently the simplest, most convenient, and intuitive way of human-computer interaction, and is widely used in electronic products such as information query, office, industrial control, electronic games, and multimedia teaching.
