Electronic device power supply control system and method

Abstract

The invention is applied to the field of power supply control and provides an electronic device power supply control system and method. In the invention, an electronic device power supply control system composed of a remote control module, an energy conversion module, a switch module and a main control module is adopted; the remote control module sends a starting radiofrequency signal to the energy conversion module when an electronic device is at a standby state; the energy conversion module, according to the starting radiofrequency signal, generates corresponding electric energy to drive the switch module to be closed and conducted; the main control module replaces the energy conversion module to control the switch module so as to ensure normal power supply by a commercial power live wire to a power demand load; and when a user needs to control the electronic device to enter a standby state, the main control module, according to a standby remote control signal emitted by the remote control module, controls the switch module to cut off the power supply path between the commercial power live wire and the power demand load so as to enable the electronic device to enter a zero-power standby state such that the problem of incapability of realizing zero-power standby in the prior art is solved.

Description

technical field [0001] The invention belongs to the field of power supply control, and in particular relates to a power supply control system and method for electronic equipment. Background technique [0002] At present, various electronic devices have been widely used in various fields, and for the purpose of reducing power consumption to save electricity expenditure costs, electronic devices can achieve low-power standby during the standby process. The dual power supply mode is adopted in the system, that is, the main power supply does not work during standby, and the auxiliary power supply supplies power to the circuit modules that need to work during standby to achieve low power consumption standby. Among them, the auxiliary power supply generally uses batteries or outdoor solar cells. If batteries are used and the standby time is long, the batteries need to be charged, which also consumes electric energy; In a place or in rainy weather, it is impossible to obtain elect...
