Computer integrated management system for a park of electronically driven mobile units

It is suggested that future development of power converter and electric drive design as a part of a system must take into account management problems. In this framework, a possible evolution of an electronically driven traction unit design is presented as a consequence of computer-integrated management systems, with special reference to the following parts of the mobile unit: (1) the data transmission network; (2) resident diagnostics using expert systems; and (3) drive controllers using expert systems. It is concluded that computer-integrated management systems to perform diagnostics and to track the life of a park of electronically driven mobile units now can be implemented using expert system development programs.<>
