Abstract

The invention provides a method for transmitting control signals of an electric appliance through voltage drop and a wire controller. The wire controller, a receiver and an electric appliance host are adopted in a method for controlling the electric appliance through power wires. The method is characterized in that the wire controller supplies power to the electric appliance host through the two power wires; the wire controller regards AC zero passage as the beginning of each time of coding, regards the duration of an alternating current half cycle as the duration of each time of coding, and regards preset voltage drop generated by an alternating current in the duration of each coding as the content of each time of coding; the receiver regards AC zero passage as the beginning of each time of decoding, regards the duration of the alternating current half cycle as the duration of each time of decoding, and regards the voltage drop condition, detected in the duration of each time of decoding, of the alternating current as the content of each time of decoding; the decoding content in the duration of each time of decoding corresponds to preset operating parameters of the electric appliance host through the receiver, and the receiver outputs the operating parameters to the electric appliance host. The invention further provides the wire controller for implementing the method. The implementation difficulty of wired wall control projects can be reduced.

Description

technical field [0001] The invention relates to a wired electric appliance control method and a wire controller for implementing the method. Background technique [0002] The human-machine interface for controlling household appliances is divided into: wired control and wireless control. For wired control, there are mainly two ways to directly set the operation panel on the electrical appliance or to separate the operation panel from the host and connect them through a communication cable. For wireless control, it is mainly realized by sending and receiving infrared signals. [0003] Although these traditional human-machine interfaces can realize the control of household appliances, they are not simple enough. For example: when using a brushless DC motor (BLDC) frequency conversion ceiling fan or dimmable LED lamps, if you want to use wired wall control to adjust the speed or brightness of these appliances, according to the existing technology, you can only Install the op...
