Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] as attached figure 1 As shown, the present invention is a multi-network inter-network coordination method for a power line broadband carrier communication network, which includes a concentrator master node completed in networking in a broadband carrier communication network with a shared power line as a carrier, and the concentrator master node periodically Send a network coordination frame for monitoring by other master nodes that are powered on but not networked in the broadband carrier communication network, wherein the network coordination frame includes

[0021] Network identification domain: contains the network identification of the master node and the network identification in the broadband carrier communication network received by the master node;

[0022] Step 1: When an unnetworked concentrator master node is initially powered on, a network...

Abstract

The invention discloses a multiple network internetwork coordination method used for a broadband power line carrier communication network, the method comprises a complete network concentrator host node and a incomplete network host node which share a power line as a carrier in a broadband power line carrier communication network, the complete network concentrator host node periodically sends a network coordination frame monitored by other power-on and incomplete network host nodes in the broadband power line carrier communication network, at last, the incomplete network concentrator host node starts networking operation. An advantage of the method is to ensure the network communication to be normal.

Description

technical field [0001] The invention relates to a multi-network inter-network coordination method for a power line broadband carrier communication network. Background technique [0002] In the electricity consumption information collection system, the concentrator used for meter reading (the function of the concentrator is to collect the data of a batch of electric meters to this device through carrier wave or 485 communication, etc., and then through wired or wireless network etc. transmitted to the master station) installed on the power side of the distribution transformer. Usually the concentrator is the communication master node, the concentrator is connected to the collector and the meter through the power line, the collector and the meter are the communication sub-nodes, each power line communication network has a network identification, and has its own communication bandwidth time. Considering the actual application situation, multiple concentrators may be installed ...
