Function Allocation Design of Subway Automatic Train Supervision System's Alarm Unit

摘要

The degree of automation in rail transit is increasing rapidly. The main responsibility of people in the subway system is transformed into monitoring. A well-designed alarm unit is a guarantee for improving the performance of personnel. By analyzing the sociotechnical complexity of the Automatic Train Supervision (ATS) system besides its alarm unit, the work domain analysis model is constructed. In the process of system model construction, the function allocation between human and automation system was considered. And the human-computer interaction interface of ATS alarm unit was redesigned. Further, the initial verification was carried out by subject matter experts in Skill-Rule-Knowledge framework. Results from this study preliminarily confirmed the reference role of cognitive work analysis in human-automation function allocation design.
