Hierarchical Networking Method Based on Master-Slave Node Communication Network

Abstract

The invention discloses a layered networking method based on a master-slave node communication network. The method comprises the steps that a master node sends a broadcast command calling a certain level of slave nodes to be connected to the network and actively delays time to wait for the slave nodes to apply for being connected to the network; all the slave nodes which receive the network connection command and are not connected to the network randomly select a certain time and carry self addresses to actively send network connection request commands to the communication network; after waiting is over, the master node sequentially performs point-to-point network connection determination on the neighbor nodes applying for network connection of the slave nodes within the period of time, and the master node distributes levels to the slave nodes; the master node performs point-to-point communication with the slave nodes which are already connected to the network and obtains the neighbor node information recorded and saved by the slave nodes; if the neighbor nodes are not connected to the network, the master node performs the network connection determination on the neighbor nodes and distributes the levels to the neighbor nodes; the steps are repeated until the neighbor nodes of all the slave nodes are all connected to the network. According to the layered networking method based on the master-slave node communication network, manual intervention is reduced, and the intellectualization and the communication success rate of the communication network are improved.

Description

technical field [0001] The invention relates to a layered networking method based on a master-slave node communication network. Background technique [0002] A communication network that includes a single master node, multiple slave nodes, and communication media is called a master-slave node communication network. The current commonly used communication methods are as follows: [0003] 1. Record and summarize the communication addresses of all slave nodes deployed in the communication network; [0004] 2. Input the communication addresses of all slave nodes in the communication network into the master node; [0005] 3. The master node actively initiates point-to-point communication with the slave node. If the communication is successful, the communication path will be recorded; otherwise, a relay will be added to continue trying to communicate. [0006] The disadvantages of the above communication methods are: 1. The communication addresses of all slave nodes must be corr...

AI Technical Summary

Problems solved by technology

[0006] The shortcomings of the above communication methods are: 1. The communication addresses of all slave nodes must be correctly recorded. If the communication addresses are incorrectly recorded or omitted, the communication will fail; 2. The communication network itself does not have an update function, and cannot actively discover new additions or replacements. 3. It takes time to form a communication path, and each slave node must be traversed to form a unique communication path; 4. If the communication path fails, the path needs to be rediscovered, and the communication efficiency is poor
