Household appliance control system based on power line carrier communication technology

Abstract

The invention discloses a household appliance control system based on a power line carrier communication technology. The system comprises a plurality of household appliances connected to a power line.The plurality of household appliances is connected to the power line through a household appliance monitoring module. The power line is also connected with a power line communication module. The household appliance monitoring module communicates with the power line communication module through the power line, and the other end of each household appliance is also connected with the oscilloscope through a coupler. The defects that a communication module control circuit needs to be independently laid or wireless sensor network nodes need to be arranged and wireless communication frequency pointsneed to be occupied in the prior art are overcome, and the defect that communication of an original power line carrier external household appliance communication module is unreliable due to the factthat the transmission distance is increased is also overcome. Remote intelligent household electrical appliance control is well realized, the reconstruction cost is saved, and the manual control box and power line conditions of existing household electrical appliances are effectively utilized.

Description

technical field [0001] The invention relates to the communication field, in particular to a home appliance control system based on power line carrier communication technology. Background technique [0002] Power line carrier communication is a unique communication method of the power system. It uses the natural network resources of the power system to realize data communication. It has the advantages of less investment, quick results, and synchronization with power grid construction. 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, an additional control line is required. And adding hardware, the cost of such construction and maintenance is also very high. At present, there are also some technical means that u...

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, an additional control line is required. 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.
