Abstract: A railway scientific research collaboration platform based on microservice architecture was designed to solve the problem of relatively low efficiency in the process of railway scientific research collaboration. Combining with the analysis of the functional requirements of the platform, this paper proposed the overall architecture, technical architecture and functional architecture of the platform, used Spring Cloud as the system microservice application framework developed based on Spring Boot, developed different functions into different components and registered as independent microservices. The platform meets the needs of all participants in the railway scientific research project to improve the efficiency of scientific research cooperation, and has certain feasibility and practicability.
