Multi-connection system and data transmission method based on wireless mesh network

Abstract

The present invention provides a multi-connection system and a data transmission method based on a wireless Mesh network, wherein the wireless Mesh network includes a root node and multiple sub-nodes, the multi-connection system includes multiple external machines and multiple internal machines, and multiple The main outdoor machine among the outdoor machines serves as the root node, and the outdoor machines except the main outdoor machine and multiple indoor machines among the multiple outdoor machines serve as child nodes, and the child nodes send data to the root node in a unicast manner. The invention can greatly reduce the amount of communication data of the multi-connection system based on the wireless Mesh network, solve the problem of data transmission congestion, improve the communication speed and communication stability of the multi-connection system, and ensure the stable and reliable operation of the multi-connection system.

Description

technical field [0001] The present invention relates to the technical field of wireless Mesh networks, in particular to a wireless Mesh network-based multi-connection system and a data transmission method. Background technique [0002] With the development of the Internet of Things technology, short-distance wireless communication technology has gradually overcome many problems in traditional wireless communication such as poor reliability, slow communication speed, and weak signal penetration ability. Called multi-line system) "wireless" becomes possible. [0003] The multi-connection system based on wireless Mesh network technology is composed of multiple external units and multiple internal units. In the wireless Mesh network of the multi-connection system, the main outdoor machine is the root node, and other outdoor machines and indoor machines are all child nodes. All nodes can connect to each other and exchange data. [0004] However, due to the large number of node...

Problems solved by technology

[0004] However, due to the large number of nodes in the multi-connection system (for example, more than a hundred nodes), all the nodes send broadcast data to each other, which will lead to a large amount of Mesh network communication data and channel congestion, which will affect the communication speed and communication reliability.

[0005] Aiming at the problem of channel congestion in the multi-connected system based on wireless Mesh network technology, no effective solution has been proposed so far
