Abstract: The maintenance technical manual of Electric Multiple Units(EMU) is still formulated in a traditional unstructured way, which has the shortcomings of high formulating cost, updating difficulty and poor communication and coordination. The introduction of Interactive Electronic Technology Manual (IETM) to manage technical documents in a structured way can reduce the cost of preparation, maintenance and update. S1000D is an international specification for the production of electronic publications, which can improve the efficiency and accuracy of IETM production with data information modularization. This paper proposed the IETM management platform for the EMU based on S1000D standards, took the maintenance technical manual for example, analyzed the key technologies, designed the general architecture, and established a collaborative work platform for editing, publishing and management. The results show that the EMU IETM management platform has high efficiency and feasibility in the compilation and maintenance of EMU technical data and can improve management efficiency according to the requirements of specific EMU operation and maintenance.
