The article provides object-oriented methodology principles as applied to modelling control systems in transport. This required taking into consideration the needs of real-time systems by enhancing modelling instruments to include capsules, ports, connectors and protocols. Object-oriented model of the system for controlling train traffic at railway station has been presented. Class diagrams, structure diagrams and state diagrams of the individual segments of the model system have been presented. The mechanisms of maintaining high reliability of the system by the reconfiguration enabling support of the controI functions in spite of the occurrence of faults have been taken into consideration.

PL

W artykule podano zasady metodologii obiektowej w zastosowaniach do modelowania systemów sterowania w transporcie. Wymagało to uwzględnienia potrzeb systemów czasu rzeczywistego poprzez wzbogacenie instrumentów modelowania o kapsuły, porty, kanały i protokoły. Przedstawiono model obiektowy systemu sterowania ruchem na stacji kolejowej. Przedstawiono diagramy klas, diagramy struktury oraz diagramy stanów poszczególnych segmentów modelowanego systemu. Uwzględniono mechanizmy utrzymania wysokiej niezawodności systemu poprzez rekonfigurację umożliwiającą podtrzymanie funkcji sterowniczych mimo występowania uszkodzeń.
