Sniffing and reading control equipment and method for Wi-SUN network test

Abstract

The invention discloses sniffing and reading control equipment and method for Wi-SUN network testing, and solves the problems that traditional equipment in the prior art is not suitable for a frequency hopping network and communication is difficult. The method comprises a sniffer mode and a reading and sending device mode. The sniffer mode is based on detection of four types of frames which can be sent by the Wi-SUN network in all time periods of the whole network so as to obtain and extract network information and evaluate network quality; a local link communication link with the node3 is established under the condition of not accessing the network in the transcriber mode, and the communication is performed. The method can effectively help a user of the Wi-SUN network to perform early-stage network distribution analysis and later-stage problem investigation, and for nodes with problems, 60% of time can be saved to judge whether network access failure is caused by the problems such as signal quality or unequal network configuration.

Description

technical field [0001] The invention relates to the field of embedded technology, in particular to a sniffing and copying control device and method for Wi-SUN network testing. Background technique [0002] For the Wi-SUN network, there is a lack of related equipment that can be used for network assessment in the early stage and problem analysis in the later stage. Traditional sniffer equipment is not suitable for frequency hopping networks such as Wi-SUN. For nodes that have already established a network, if they want to communicate with him, they can only join this network first, and then communicate with them through UDP or TCP after obtaining the IPv6 address of the destination node. The master node is root, and then root forwards data, and the function of sniffer and point-to-point communication are not integrated on one device. [0003] In the existing technology, first of all, for the Wi-SUN network, if it works in the frequency hopping mode, it is impossible to captu...

AI Technical Summary

Problems solved by technology

[0005] The present invention is to overcome the problem that traditional equipment in the prior art is not suitable for frequency hopping networks and difficult communication, and provides a sniffing and copying control equipment and method for Wi-SUN network testing. The present invention can be used for Wi-SUN networks The signal analysis during network deployment in the early stage is used to select the node location and test whether a certain place can cover the Wi-SUN network signal, and can be used for later problem analysis. It can communicate with the node point-to-point without accessing the network, obtain and configure Node information, data communication with nodes
