Embodiment 1

[0020] In order to realize communication between the primary subnet and the secondary subnet, this embodiment discloses a power carrier communication networking method, please refer to figure 2 , the method includes the following steps:

[0021] Step 100, divide the communication network with the central control node and multiple common nodes into one primary subnet and N secondary subnets, where N is an integer greater than or equal to 1. The primary subnet includes a central control node CCO and at least one common node (station, STA). The broadband carrier is not reachable between the primary subnet and each subnet, but the broadband carrier is reachable between nodes belonging to the same subnet. For broadband, it is necessary to build a network to complete the establishment of the communication mechanism. Please refer to figure 1 , each network node is allocated as a central control node CCO and a common node. The central control node CCO is responsible for network es...

Embodiment 2

[0040] Corresponding to Embodiment 1, this embodiment provides a power carrier communication networking device, please refer to image 3 , the power carrier communication networking device includes: a subnet division module 10, a carrier mode switching module 20, a test signal sending module 60, a carrier communication test module 30 and a main subnet multiplexing node determination module 40, wherein,

[0041] The subnet division module 10 is used to divide the central control node CCO and a plurality of ordinary nodes into 1 main subnet and N subnets, N is an integer greater than or equal to 1; the main subnet includes the central control node CCO and at least one Ordinary nodes, the broadband carrier is unreachable between the main subnet and each subnet, but the broadband carrier is reachable between nodes belonging to the same subnet.

[0042] The carrier mode switching module 20 is used to switch each common node of each subnet to the narrowband carrier mode.

Abstract

The invention discloses a power line carrier communication networking method, device and system. The method comprises the steps of dividing a communication network with a central control node and a plurality of common nodes into one master subnet and N secondary subnets; all common nodes in the master subnet respectively sending test signals to all secondary subnets by a narrow band frequency; separately receiving response messages fed back by common nodes capable of receiving the test signals in the secondary subnets, so as to test the common nodes capable of reaching the secondary subnets from a narrow band carrier in the master subnet; and selecting at least one common node capable of reaching the secondary subnet from the narrow band carrier in the master subnet, and setting the communication mode of the selected common node as a multiplex mode of a broadband carrier and the narrow band carrier. As the test signal is sent by use of the narrow band frequency, and the communication mode of corresponding common node in the master subnet is set as the multiplex mode of the broadband carrier and the narrow band carrier, the transmission distance of broadband carrier data transmission is prolonged.
