Signal transfer socket-switch for remote control of household electrical appliances

Abstract

The invention relates to a signal transfer socket-switch for remote control of household electrical appliances. The signal transfer socket-switch comprises a socket-switch, a power source transformation module, a carrier wave transmission module and an infrared module, wherein the carrier wave transmission module employs a bidirectional electronic carrier chip and can realize reception and transmission of signals, and a logical judgment and signal identification function is added into a program; and the infrared module comprises a receiving part and a transmitting part. The signal transfer socket-switch provided by the invention employs the socket-switch equipped with the carrier wave transmission module and the infrared module to realize conversion between an infrared radio-frequency signal and a carrier signal and utilizes a power line to transmit the carrier signal, so an infrared radio-frequency signal transmitted by a remote control system or by a remote controller in room is transferred among rooms in the form of electric carrier waves; and thus, through-wall remote control of the functions of electric appliances can be realized.

Description

technical field [0001] The invention relates to a socket switch, in particular to a signal transfer socket switch for remote control of home appliances. Background technique [0002] Most of the existing remote home appliance control systems are mainly used to control the switches of electrical appliances. Although some products can remotely control the functions of electrical appliances, because household appliances generally use infrared radio frequency signals, and infrared radio frequency signals have poor wall penetration, so this part The product can only remotely control electrical appliances in a small area. For a residence with many rooms or a multi-storey residence, multiple devices are required to achieve the remote control effect, which increases the cost of installation and maintenance, and blindly increasing the RF transmission power will cause Interference with other equipment, prone to misoperation and other problems, resulting in potential safety hazards. ...
