Carrier communication system

Abstract

The invention relates to a carrier communication system which comprises an electric power communication master device, an electric power communication slave device, an electric power communication master node and an electric power communication sub-node. The power communication master device and the power communication slave device are respectively connected with the power line and communicate with each other in a power line carrier communication mode; the electric power communication main equipment is used for accessing a communication network; the electric power communication master node is in communication connection with the electric power communication slave equipment; the electric power communication sub-node is used for being in communication connection with the controlled device, and the electric power communication slave device is used for being in communication connection with the master control device. According to the scheme, the carrier communication network can be formed by means of the power line, and the problems of insufficient communication distance and inconvenient wiring of the smart home system are solved; networking is convenient, expandability is high, networking can be completed by directly connecting the controlled device to the electric power communication child nodes, and extra wiring is not needed.

Description

technical field [0001] The present application relates to the technical field of carrier wave communication, and in particular, to a carrier wave communication system. Background technique [0002] At present, the main application field of carrier communication is the power meter reading industry. Because of its unique carrier coupling communication method, it is very suitable for the current meter reading industry. The communication signal is loaded on the power line without re-laying the communication line. Compared with the wireless communication method, the transmission distance farther and more stable. However, there are few application cases of carrier communication in domestic or industrial places. [0003] In related technologies, smart home systems usually use communication methods such as WiFi, Bluetooth, etc., which have poor wall penetration, insufficient communication distance, and limited control capabilities; if a wired network is used, it is inconvenient to ...

However, there are few application cases of carrier communication in household or industrial places

[0003] In related technologies, smart home systems usually use WiFi, Bluetooth and other communication methods, which have poor wall penetration, insufficient communication distance, and limited control capabilities; if wired networks are used, it is inconvenient to lay network cables in the home, and the workload is heavy; In addition, carrier communication cannot be transmitted between different voltage levels, and communication across voltage levels cannot be realized
