Problems solved by technology

Although this type of electronic device 3 can control the power supply unit 33 to stop supplying power to the central processing unit 34 through the switch 311 to avoid power consumption, but because the switch 311 is a mechanical switch, it is easy to bounce at the moment the switch is toggled, resulting in system power failure. Crash due to unstable supply

Abstract

A power supply control module of an electronic device comprises a central processing unit, a switch unit which is electrically connected with the central processing unit and a logical unit. An input end of the logical unit is electrically connected with the switch unit and the central processing unit, and an output end thereof is electrically connected with a power supply unit of the electronic device. A switch signal is output to the central processing unit and the logical unit by pressing the switch unit, thus the logical unit controls the power supply unit to supply power to the central processing unit, at the same time, when the central processing unit judges that the switch signal is a starting signal, a power supply signal is output to the logical unit to control the power supply unit for sustained power supply, when the central processing unit judges that the switch signal is a closing signal, a power-off signal is output to the logical unit to control the power supply unit to stop the power supply.

Description

technical field [0001] The invention relates to a control module, in particular to a power control module of an electronic device and a power control method thereof. Background technique [0002] refer to figure 1 , an existing electronic device 1 has a central processing unit 11, a system switch module 12, and a power supply unit 13 for supplying electric power required by the electronic device 1, the power supply unit 13 is electrically connected to the central processing unit 11, and can be An energy storage device detached from the electronic device 1, such as various batteries such as dry batteries and lithium batteries. The system switch module 12 is electrically connected to the central processing unit 11 and has a system switch 121 which can be pressed to control the central processing unit 11 to execute a boot process, so that the electronic device 1 enters a boot mode for user operation. When the electronic device 1 is in the power-on mode, when the system switch...
