Household electrical appliance control system based on high efficiency modulation-demodulation power line carrier communication technology

Abstract

The invention discloses a household electrical appliance control system based on the high efficiency modulation-demodulation power line carrier communication technology; the control system comprises aplurality of household electrical appliances connected on a power line; the plurality of household electrical appliances are connected to the power line through a household electrical appliance monitoring module; the power line is also connected with a power line communication module; the household electrical appliance monitoring module communicates with the power line communication module through the power line. The power line communication module serves as an internet of things node communication module; the high efficiency modulation-demodulation technology can ensure the communication module to have a higher data code rate and stronger anti-interference capability, and the communication distance is serialized. The power line carrier wave household electrical appliance control system based on the high efficiency modulation-demodulation communication technology can solve the problems in the prior art that a communication module control line needs to be singly paved or wireless communication frequency points are occupied, and a conventional electric power carrier wave external household electrical appliance communication module is not reliable in communications, thus well remotely controlling intelligent household electrical appliances, saving reconstruction cost, and effectively using existing household electrical appliance controller and power line conditions.

Description

technical field [0001] The patent of the present invention belongs to the technical field of Internet of Things products, and specifically relates to a remote home appliance control system. Background technique [0002] With the introduction of Industry 4.0, the industry has developed from informatization to intelligence. The Internet of Things is an important part of intelligence. How to connect existing household appliances into the ecology of the Internet of Things is a problem that those skilled in the art need to face directly. [0003] The current smart home appliances are often connected to the Internet of Things system by adding a communication module with remote control. This method requires the control line of the communication module to be laid separately. On the one hand, the communication method is relatively backward, and on the other hand, additional control is required. Lines and additional hardware, the cost of such construction and maintenance is also ver...

Problems solved by technology

[0003] The current smart home appliances are often connected to the Internet of Things system by adding a communication module with remote control. This method requires the control line of the communication module to be laid separately. On the one hand, the communication method is relatively backward, and on the other hand, additional control is required. line and additional hardware, the cost of such construction and maintenance is also very high

At present, there are also some technical means that use the external home appliance communication module through the power line carrier. Although this method solves the problem of erecting the control line, it is vulnerable to the inherent pulse interference of the power line itself, and the problem of unreliable communication has emerged.
