Design of Network Based On-Board Computer System

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 trainset 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 engineering design and test of on-board computer system that ensures the safety and reliability of KHST. The design is focused at Train Communication Network(TCN) interfaced distributed processing system.
