Electric appliance control method based on power line carrier communication and control device thereof

Abstract

The invention discloses an electric appliance control method based on power line carrier communication and a control device thereof. The electric appliance control device comprises a control terminal and a wireless remote controller; a wireless transmission receiving module is arranged in the control terminal, and connected with a wireless transmission sending module arranged in the wireless remote controller by signals; and a power line communication sending module is also arranged in the control terminal, an input end of the power line communication sending module is connected with the wireless transmission receiving module by a circuit, and an output end of the power line communication sending module is connected with a power line communication receiving module of at least one controlled electric appliance through a wire cable of a power line. Because the technical measures of wireless communication and power line carrier communication are combined, through wireless communication, the method and the device ensure that a wireless control signal has no directivity and that the transmission distance of a transmitted control signal is far and is not interfered through a wire cable carrier of the power line, and well achieve the intelligent transformation of the prior families without rewiring.

Description

technical field [0001] The invention relates to the field of smart home design technology and electrical equipment, and more specifically, to an electrical control method based on power line carrier communication and an improvement of the control device thereof. Background technique [0002] With the development of science and technology, smart home is getting more and more attention. It is often seen in many sci-fi movies that a controller can control all the electrical appliances in the entire home. In real life, there are indeed many smart home electrical equipment. Usually it is controlled by a computer, and the control signals are also transmitted through wired cables, and some control signals are purely dependent on the 2.4G wireless network; and the cost of the smart home realized in this way will be high, and it is also difficult to use. It is more complicated, and at the same time, this kind of home must be wired network wiring or wireless network layout in the ea...

AI Technical Summary

Problems solved by technology

However, there are some problems in these two ways: the use of network wiring control mode needs to increase the wired control network in the early stage of home design, and at the same time, it needs to use computer-aided control, which cannot realize the intelligent transformation of the home, and can not do it at the same time. Low energy consumption; the mode of using the wireless receiving module needs to add a wireless receiving module to each electrical appliance, which increases a lot of cost. At the same time, it must be wirelessly paired one-to-one before the control can be controlled.

[0004] Therefore, the existing technology still needs to be improved and developed
