Model-Driven Study of Intelligent Passenger Information System for Urban Rail Transit
摘要
The passenger information system (PIS) of urban rail transit consists of three major functions: Public Address (PA), Closed Circuit Television (CCTV) and Passenger Information Display (PID). Their functions are independent of each other, with low integration and development efficiency. To solve these problems, the three functional modules of PIS were modularized, and the Model-based Systems Engineering (MBSE) concept was adopted to model the PIS, proposing the Intelligent Passenger Information System (IPIS). Based on the characteristics of classic MBSE and IPIS, a new modeling IPIS method is proposed in this paper, which will complete the design of complex systems after considering stakeholders, relevant requirements, and use case scenarios. A performance metamodel, functional metamodel, and system requirement metamodel of the IPIS system have been established to meet the modeling process of IPIS, which will improve the reuse rate of the model and shorten the design cycle.
