Abstract:

This paper designs and implements a big data’s storage and analysis system of railway signal system based on Hadoop. Firstly, this paper studies the working principle of Hadoop distributed system, HDFS (the Hadoop distributed file system) and MapRedeuce model. And then, APIs of signal data analyzers about files of txt and CSV are designed. The storage, distribution and management of files and data are achieved by HDFS. According to the structure of all data files, this paper uses HBase to design methods which can find the data file in a quick time and design the API about all the operations in HBase. Finally, this paper uses ExtJS to build the front-end display page, communicate with the Hadoop platform through the server to complete the electrical characteristic analysis and log analysis, and display the data processing results with the list, graph and scatter diagram. This paper has accomplished the data mining and visualization of the work.

Key words: big data, Hadoop, MapReduce, data storage and analysis, railway signal system
