A smart household central controller (1), terminal (2), system and control method. The smart household central controller (1) is connected to the smart household terminal (2) by a power line, namely, a bus way of performing serial communication by using the power line is adopted; after receiving a household control command that has a digital signal format and is sent by a household control terminal (3) (for example, a mobile phone terminal), the smart household central controller (1) converts the format of the household control command into an analog signal format and then sends the household control command with the analog signal format to the smart household terminal (2) by means of the power line; and after receiving the household control command by means of the power line, the smart household terminal (2) converts the household control command into a digital signal and then performs subsequent processing. Therefore, by adopting a new networking mode of a power line, the connection reliability of a smart household is not limited by household terminals or building types, transmission signals do not obviously attenuate and are not limited by a transmission distance, and there is not a great deal of wireless radiation, such that the networking mode is better in reliability and more environmentally-friendly. |
