Arm-based Data Monitoring And Data Fusion

The operation of railway equipment in the actual process, because the complexity of the environment, often by including a variety of information, including lightningNo interference caused by failure. And at this stage, when the railway equipment failure due to lightning and other reasons, the absence of an effective method to determine the actual cause of failure is often rely on the experience of the staff to carry out. Especially the failure set the scene more prepared, when lightning occurs, may produce a series of chain reactions, leading to equipment failure in batches. Therefore, in order to better identify and diagnose faults, the fault for the failure in the diagnosis provide the basis for the formation of a data monitoring system is very necessary.This article focused on building the system in the software level. Software system is embedded Linux-based, using the Qt programming language constructs completed. ARM9 based hardware of the system board. The entire software system consists of financial data and data detection subsystem. Among them, the data detection and sampling system is mainly the terminal for data communications. Sampling involves multiple terminal coordination and how to dealing with them. Data fusion subsystem is focused on the data after the fault analysis, including data curve display, data extraction and storage of characteristic values and the correlation between the terminal manual identification.The writer gives in the text of the module's software requirements analysis, software design and software implementation of relevant programs. Using both soft pieces of software simulations of the output made some presentations and analysis. Finally, for a summary of the contents of this paper and pointed out that how to correct the deficiencies of the system and method.
