Intelligent household control method

Abstract

The invention discloses an intelligent home controlling method, which solves the technical problem of reducing the cost of home control. The method comprises the following steps: when a user presses a key of a wireless control center, the transmitting module transmits a wireless signal out, after a wireless control signal receiving center receives the signal, the control signal converts the analog signal into a digital signal through a power line communication control module, the digital signal is transmitted on a power line after modulation, low-pass filtering and amplification, a power line communication receiving module receives and demodulates the digital signal to obtain the control signal, and the control signal is communicated with an electric appliance through a serial port or an IIS to control the work of the electric appliance. Compared with the prior art, since the wireless control signal transmission is adopted, the communication signal is transmitted by using the power line, the invention has the advantages of long transmission distance, no directivity and no interference, the rewiring is not required, the intellectualized modification of the current home conditions is convenient, the structure is simple, and the cost is low.

Description

technical field [0001] The invention relates to a control communication method for household appliances. Background technique [0002] With the development of science and technology, smart home has been paid more and more attention by people. In Hollywood sci-fi movies, we often see that a controller controls the home appliances of the whole family. In real life, there are also many smart homes. The smart home implementation mode in the prior art is generally controlled by a computer, using the control network wiring, the control signal is transmitted through a wired cable, or relying on the 2.4G wireless network, and adding a wireless receiving module to each home appliance. The smart home realized in this way is costly, requires computer-aided control, has a complex structure, high energy consumption, and is inconvenient to use. At the same time, this kind of home structure must be wired or wireless network layout in the early stage of family house design, which cannot b...

The smart home implementation mode in the prior art is generally controlled by a computer, using the control network wiring, the control signal is transmitted through a wired cable, or relying on the 2.4G wireless network, and adding a wireless receiving module to each home appliance. The smart home realized in this way is expensive, requires computer-aided control, has a complex structure, high energy consumption, and is inconvenient to use. At the same time, this kind of home structure must be wired or wireless network layout in the early stage of family house design, which cannot be realized. Smart Home Transformation
