Abstract: This paper carries out requirements analysis of the interlocking system in the teaching and training base of a university, and focuses on the application characteristics of such scenarios as its daily teaching and practical training, qualification examination for railway locomotive driver and occupational skill appraisal for signaling professional. The computer based interlocking system is used to drive the switching relay interface, and the integrated design of the interlocking operation indication and control circuit is adopted to implement the two control modes of the interlocking system, i.e., "simulated control and field control", and achieve the one-key switching between the two control modes.

Key words: interlocking system in teaching and training base, simulated control, field control, integrated design
