Design Of Offline Analysis Tool For Network Record Analysis System Of Digital Traction Substation

Network record analysis system was a kind of communication network detection system which was widely used in digital traction substation.With the monitor,capture,analysis and storage of the message,network record analysis system can realized the collection,measurement,monitoring about the traction substation information automatically.Therefore,the Network record analysis system had important application value.Firstly,based on the analysis of the main connection structure and network data transmission model of digital traction substation,the requirements of information interaction were identified.Secondly,according to the requirements of information exchange,the structure,function and technical index of the network recording analysis system were analyzed in the digital traction substation.Thirdly,based on the data exchange model about online analysis tools,offline analysis tools and configuration tools,the specific functions of offline analysis tool for network record analysis system were configured.With the functions of message reading,retrieval,alarm,depth analysis and waveform display,the offline analysis tool for network record analysis system was developed by QT platform.The message reading module realized the decoding of ".Pcap" message file.The message alarm module realized the alarm to the message sequence error.The message depth analysis module realized the analysis to the message frame format and data.The waveform display module realized the display about the fault waveform.Finally,the high validity of the software was manifested by Wireshark contrast verification.
