An electronic device power supply control system and method

Abstract

The invention is applicable to the field of power supply control, and provides a system and method for power supply control of electronic equipment. In the present invention, by adopting a power supply control system for electronic equipment including a remote control module, an energy conversion module, a switch module and a main control module, the remote control module sends a starting radio frequency signal to the energy conversion module when the electronic equipment is in a standby state, and the energy The conversion module generates corresponding electric energy according to the starting radio frequency signal to drive the switch module to close and conduct, and then the main control module replaces the energy conversion module to control the switch module, so as to maintain the normal power supply of the mains live wire to the electric load, and when the user needs to control When the electronic equipment enters the standby state, the main control module controls the switch module to cut off the power supply path between the mains live wire and the electric load according to the standby remote control signal sent by the remote control module, so that the entire electronic equipment enters a zero-power standby state, which solves the problem of existing The existing technology cannot realize the problem of zero power consumption standby.

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...
