Research on the Information Sharing Framework in Railway Construction Driven by Block Chain Technology

Research purposes: The engineering data generated in the process of railway construction in China is increasing day by day. In order to solve the problems such as high organizational structure trust cost and poor information data security in the transfer process of railway big data, the information sharing framework based on block chain technology was proposed to improve the data architecture system of railway informatization construction. Research conclusions:(1) Three key block chain technologies, namely consensus mechanism, intelligent contract and digital signature, have strong applicability for solving information sharing problems such as railway engineering information collection, processing and query; (2) On the basis of clarifying the information sharing flow process of railway construction projects, establishing the information sharing framework driven by block chain technology can improve the information sharing degree of railway construction projects; (3) It is feasible to apply the railway engineering information sharing framework to the actual railway construction management, and it can effectively solve the problems such as weak trust among various units, low approval efficiency and data insecurity in the project acceptance management. © 2020, Editorial Department of Journal of Railway Engineering Society.
