The Design Of The Data Collection & Network System For Locmotive Examine

The paper aimed at the system of locomotive examined and repaired data collection and network transmission in Baoji Electric Locomotive Section as its researching object. By means of the integrated research about the function the whole system will reach, and contrast and analysis of several technical schemes, the paper eventually determined the scheme.The first part of the paper discussed the locomotive examined and repaired data management and status and existent abuse in China; clarified the effect of the locomotive Section information while management, and clarified the need of whole management of locomotive examined and repaired data and its coming income; and more brought forward the important of locomotive examined and repaired data collection and network transmission in locomotive section; introduced the task the paper will be finished.The second of the paper analyzed and compare with the several schemes, conformed network scheme, bunch communication scheme, database scheme, and conformed query mode.The third of the paper finished several stations setting of theit-mmBaoji locomotive Section and analyzed their functional demand, finished the design of the network including integrating several factors, conformed network-running mode and selective protocol, and analyzed their security and dependability.The forth of the paper finished the hardware and software design of the whole system, including data collections, transmission controllers in several stations, the part of receivers, the part of data processor and the server transmission network; it also finished the analysis of running process of the while system.
