Abstract: The conditions of railway communication equipment directly affects the safety and efficiency of railway transportation. In order to monitor and manage the railway communication equipment and facilities, and meet the need of information sharing and analysis, this article proposed the technology scheme to build a big data platform for communication equipment and facilities. The scheme included the platform overall architecture, function architecture, network architecture, technical architecture and data interface design. Construction and application of the platform would implement the whole life cycle management of communication equipment, and provide comprehensive application services for fault prediction and state evaluation.
