Abstract

The present disclosure relates to a power supply system based on power carrier communication, a communication method thereof, electronic equipment, and a storage medium. The power supply system includes a power supply circuit, a signal isolation circuit, and a power carrier communication circuit. Among them, the signal isolation circuit includes an input signal isolation circuit and an output signal isolation circuit; the power carrier communication circuit includes a central controller CCO, a signal transmitting coupling circuit, a signal receiving coupling circuit, and a sub-gateway STA. By constructing a power supply circuit based on multiple signal isolation circuits, the present disclosure shields interference signals from external sources of the power grid and internal source interference signals of switching signals in the power grid, and realizes the intercommunication and interaction of power carrier communication during low-voltage power supply for households. The stability of the power supply system.

Description

technical field [0001] The present disclosure relates to the technical fields of smart furniture and communication, and in particular, to a power supply system based on power carrier communication, a communication method thereof, electronic equipment, and a computer-readable storage medium. Background technique [0002] Power carrier communication is a communication technology that loads communication signals on the AC mains. It has been widely used in remote meter reading and photovoltaic fields in the early years. It has the characteristics of safety, stability, anti-interference, and strong data confidentiality. In the current smart home , mainly using the AC mains wire as the signal channel, with the PLC central controller (CCO for short) as the core, and a complete control system composed of multiple PLC sub-nodes (STA for short). [0003] When many devices need to be in the same AC mains network, the power grid in the home is often complex, with inductive and capacitiv...

AI Technical Summary

Problems solved by technology

[0003] When many devices need to be in the same AC mains network, the power grid in the home is often complex, with inductive and capacitive loads such as air conditioners, washing machines, and floor heating. These devices have large signal interference during operation, which will cause The control equipment of the power carrier communication is out of control and the data packet is dropped

At the same time, more and more smart devices in existing households are powered by DC power supply based on switching power supply. The electromagnetic interference generated by switching power supply has a great impact on power carrier communication, and because it needs to be in standby state for a long time, the standby power consumption is large. Energy loss is also quite serious
