Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with specific examples.

[0034] A networking method based on a backbone Mesh networking communication protocol, the method is applied to a centralized meter reading system, and the centralized meter reading system includes a concentrator, a centralized meter reading management system, several terminal devices, and several relays, wherein the terminal device It includes a directly connected terminal device directly connected to the concentrator, and a non-directly connected terminal device interacting with the relay.

[0035] The concentrator is directly connected to the centralized meter reading management system, quickly communicates with the directly connected terminal equipment, uploads data in its own time slice and uses the previously configured dedicated frequency band, the concentrator interacts with the relay node, and all relays interact with the terminal equipment independently. Th...

Abstract

The invention provides a networking method based on a backbone Mesh networking communication protocol, the method is applied to a centralized meter reading system, the centralized meter reading system comprises a concentrator, a centralized meter reading management system, a plurality of terminal devices and a plurality of relays, wherein the terminal equipment comprises direct connection terminal equipment directly connected with the concentrator and non-direct connection terminal equipment interacting with the relay. The networking method is suitable for relay and terminal equipment with low power consumption requirements, the communication success rate and efficiency can be improved, frequent communication of the equipment is reduced, and controllability of battery loss is guaranteed; and through a frequency division and time division mode and a relay independent centralized reading mode, the time and power consumption overhead for traversing all devices in a high-capacity networking environment are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of networking methods, and in particular relates to a networking method based on a backbone Mesh networking communication protocol. Background technique [0002] The networking methods in the prior art include: [0003] 1. Polling point copy + ACK: The concentrator wakes up the mounted devices in turn according to the white list and completes the data point copy until the polling point copies all devices. For example, the concentrator copies device A and waits for the ACK. If the ACK fails, it continues to copy device A. If the ACK succeeds, it continues to copy the next device. [0004] 2. Group copy + window competition report: [0005] Group copy wakes up the mounted devices in a CAD group and sends a broadcast packet for group copy, and then opens a fixed-period receiving window, and each device reports data after a random delay. And inform the device whether the acquisition is successful in the next ...
