Discussions on Comprehensive Inspection and Monitoring Technologies for Railway Infrastructures

From the views of inspections, monitoring, data analytics and other aspects of high speed rail infrastructure, developing directions of comprehensive inspection and monitoring technologies of high speed rail infrastructure in China are discussed in this paper. To address the demand to integrate comprehensive repairs and production in the fields of track maintenance, electric equipment maintenance, and power supply maintenance of high speed rail, comprehensive inspections and on-board inspection equipment are developed coordinately, fixed monitoring devices and small professional inspection devices are unified, and a comprehensive and integrated system for monitoring and inspecting rail infrastructures is constituted based on such principles as "concentrated resources, integrated management and comprehensive applications". At the same time, the construction of management information systems of railway maintenances and operations is enhanced, and the development of infrastructure safety monitoring methods is facilitated and modernized by means of data processing, integrated analysis and data mining technologies so as to detect the potential safety issues in advance, analyze and understand the evolutions of infrastructure conditions, and predict their variation tendencies. Predictive maintenances will be implemented based on the conditions of the facilities. Finally, in view of current inspection and monitoring systems in China, creative suggestions are proposed in terms of comprehensive inspection technologies, compre-hensive repair management technologies and analysis/applications of inspection data.
