Design of on-board computer system for Korean High-Speed Train

Currently KERI is participating a project whose goal is to develop the Korean High Speed Train (KHST) with maximum speed of 350kph. KERI's responsibility is the electrical system engineering that includes engineering design of an on-board computer system for diagnosis and control of train set and electrical/mechanical devices. A system engineering approach of the design is performed in order to guarantee the passenger safety and economically viable train for construction, operation and maintenance. This paper presents the draft engineering design of on-board computer system that ensures the safety and reliability of KHST. The draft is focused at network interfaced distributed processing system.
