In this paper the GK 1F diesel locomotive microcomputer on-board hardware and software design,technique parameters,anti-interference measures and especial controlling functions adapting to GK 1F locomotive are introduced in details.

By analysing working conditions of locomotive and application conditions of microcomputer on-board, the article induces all kinds of typical malfunction models of microcomputer on-board at first and then analyses the behavior, distribution and parameter estimation of these typical models.

Through the analysis of DF 6 locomotive microcomputer controlled operating systems, how to realize the real time management and dispatching of tasks under the real time and multi task condition of on board microcomputer controlled systems was discussed, and the time management of this system was analyzed and calculated in detail.

This paper briefly states the structure of the new on board microcomputer control system, including its hardware components, main control function, communication and display system function.
