Problems solved by technology

This method takes a lot of time due to the need to enumerate one by one, and it is difficult to maintain
However, open and more efficient multiple networking protocols such as Zigbee, etc., either need to pre-determine the role of the device during networking, such as a router or an endpoint device; or require expensive costs, such as the Lonwork network

Embodiment Construction

[0039]In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0040] Before the method provided by the present invention is described in detail, some concepts that will be used in the present invention are described as follows:

[0041] 1) Logical ports (hereinafter referred to as port numbers)

[0042] The point-to-point connection of the present invention is all set up on the logical port of two equipments, in conjunction with actual tree cluster network, logical port number is set as a byte (0~255), and wherein 0 port is reserved for the local port of parent node, 255 is the broadcast port, and 254 is the network management port.

[0043] 2) Logical address

[0044] The network formed by the method provided by the present invention has a concentrator and K-level equipment nodes, and the logical addresses of the concentrator and each equipment node are divided into K+1 sections, wherein t...

Abstract

The invention relates to a routing networking method suitable for centralized collection network (i.e. cluster tree type), which is an effective and low-overhead distributed networking method designed based on a wireless or low-voltage power line carrier centralized network networking. The invention provides a centre-point recruitment method. Another technical scheme of the invention is to provide a cluster-tree type network routing and networking method using the centre-point recruitment method. The invention also provides a method for carrying out device relaying by using a network formed by the networking method. The invention further provides a method for accessing the device into the network formed by the networking method. The invention has the advantages that an effective networking method which needs no predictable device network roles, device Mac address or other information and is capable of supporting automatic relaying is provided for centralized collection network.

Description

technical field [0001] The invention relates to a routing networking method suitable for a centralized collection network (i.e., a tree cluster type), which designs an effective and low-overhead distributed networking method for a centralized network networking based on wireless or low-voltage power line carrier method. Background technique [0002] At the installation site of a centralized acquisition network such as a centralized meter reading system for electric meters, the installation of each equipment point is often scattered and the location cannot be modeled. The site situation is complex and often requires multi-level relays. The previous inefficient method adopts the method of device enumeration, that is, by designing some specific constraints, the concentrator performs relay networking tests on the endpoint devices one by one. Because this method needs to enumerate one by one, it takes a lot of time and is difficult to maintain. However, multiple networking prot...
