Abstract:

Track circuit operation,maintenance and management of the process will produce massive heterogeneous multi-state data,that is,big data.Their efficient,reliable and inexpensive storage and quick access and analysis are currently an important research topic.The article first analyzes the characteristics of generation sources and track circuit failure detection in all aspects of big data,and reviews the current business,Internet and industrial monitoring large areas of the existing data-processing technique.A detailed analysis of these techniques in response to the track circuit troubleshooting and large data processing strengths and weaknesses is made.Finally the opportunities and challenges of big data track circuits are discussed in perspectives of large data storage,real-time data processing,heterogeneous integration of multiple sources of data,and large data visualization.

Key words: track circuit;big data;cloud computing;parallel database
