CRH series Electric Multiple Units (EMUs) are equipped with a variety of advanced sensors and diagnostic units, which can generate real-time monitoring and diagnostic data representing the current technical states of their essential sub-systems. Timely acquiring and analyzing the monitoring and diagnostic data is significant for operation monitoring, emergency response and routine maintenance. To relieve the inconvenience of uploading and handling the data from different types of EMUs and to enhance the efficiency and effects of utilizing the dynamic data, the railway operation authority launched a project to work out an integrated solution and focus on formulating related technical specifications to build a unified train data wireless transmission and management system for CRH series EMUs. This paper addresses the requirements for such a unified system and summarizes the preliminary results of the project. Keywords: train monitoring and diagnostic data, wireless data transmission, remote monitoring, management system, vehicle maintenance, standardization.
