Power line carrier communication ad hoc network implementation method

Abstract

The invention discloses a power line carrier communication ad hoc network implementation method. The method comprises the following steps: sending a networking command through a host, carrying out networking reply through non-networked slaves, sending a handshake command after the host receives the networking reply, receiving a networking address after the slaves receive the handshake command, carrying out handshake reply, and confirming that the slaves complete networking after the host receives the handshake reply. According to the invention, different random numbers are generated by using the unique identity identification numbers of the slaves, different delay time is generated according to the random numbers, and when the host initiates networking, only one fastest slave performs networking reply each time, so that sequential networking of the slaves is realized, and the reliability and stability of networking are improved; and when a communication packet is lost and the host doesnot receive the handshake reply, the slave corresponding to the broadcast command is unnetworked, so that the host is prevented from allocating the same networking address to the plurality of slaves,the networking speed is high, the networking success rate is high, and the networking is more stable.

Description

technical field [0001] The invention relates to a networking method, in particular to a method for implementing an ad hoc network for power line carrier communication. Background technique [0002] Power line carrier communication is a unique communication method for power systems, and is a technology for transmitting analog or digital signals through carrier waves. The biggest advantage of the power line carrier is that there is no need to re-set up the network, the cost is low, and the layout and maintenance are convenient. In the traditional power line carrier system, because the concentrator is far away from some sub-nodes, it needs to go through one or more relays to communicate. Generally, a routing path for communication between all sub-nodes and the main node is established in advance. When there is a communication demand , directly use the pre-established path for data transmission. [0003] However, the power line is not a good communication medium, and the commu...

Problems solved by technology

[0003] However, the power line is not a good communication medium, and the communication link between nodes is asymmetrical, that is, the communication quality of the uplink and downlink communication links is related to the specific environment, and there may be large differences, especially when there is a link between the master node and the child node. If the link quality is good but the communication quality of the reverse link is poor, the data transmission will fail when returning along the original path. Therefore, a power line carrier communication ad hoc network implementation method is proposed to improve the reliability of the power line carrier communication network and stability, and reduce the cost of network deployment, it is very necessary
