Problems solved by technology

The disadvantage of this system is that it is complex to operate
[0006] The power carrier technology invented in the 1970s has been used in the field of home intelligence. The principle is to use the power line as the carrier to transmit the control signal. The advantage of this method is that no additional wiring is required and the control is relatively simple. The disadvantage is that the power line The noise is large, the signal is easily interfered, and the reliability of the system cannot reach 100%.
Therefore, this technology has not been widely promoted until now.

Abstract

The invention relates to a family appliance control system, which comprises: a family appliance connected to a dual-wire switch; a dual-wire switch connected to a control switch, a trigger device parallel connected to two ends of family appliance; a controller whose input is connected to the trigger device and output is connected to the control switch to control the family appliance; one or several remote controllers connected to the controller while the character of family appliance is displayed on the remote controller; the remote controller via the controller can control family appliance. With said invention, user can control family appliance traditionally or remotely. The invention can make the controlled object feedback itself state in time. Said system can directly and simply control family appliance.

Description

technical background [0001] The invention relates to the technical field of automation, and more specifically relates to a control system for household appliances. Background technique [0002] At present, in terms of intelligent control of household appliances, the control of home appliances mainly includes infrared control, radio frequency (RF) control, and control through keyboard or voice system. [0003] Infrared control is that the remote control sends out infrared remote control signals, and the infrared receiver performs actions after receiving relevant signals, such as ordinary air conditioner remote control; or the remote control directly controls the switch equipped with the infrared receiver, usually this switch is a two-wire Switch, you can choose a mechanical switch, or you can choose an infrared remote control. The disadvantage of this control method is that the control range is small, and there must be no barrier between the receiver and the transmitter, so ...
