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 port (hereinafter referred to as port number)

[0042] The point-to-point connection of the present invention is established on the logical ports of the two devices. Combined with the actual tree cluster network, the number of logical ports is set to one byte (0-255), and the port 0 is reserved for the local port of the 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, ...

Abstract

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. The invention provides a method for recruiting a central point. Another technical solution of the present invention is to provide a tree-cluster network routing and networking method using the above-mentioned central point recruiting method. Another technical solution of the present invention is to provide a method for relaying and forwarding devices using the network formed by the above-mentioned networking method. Another technical solution of the present invention is to provide a method for a device to automatically access the network formed by the above-mentioned networking method. The advantage of the present invention is to provide an effective networking method for the centralized collection network that does not need to predict information such as device network roles and device Mac addresses, and supports automatic relay and forwarding.

Description

technical field [0001] The invention relates to a routing networking method suitable for a centralized collection network (that is, 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 p...
