Simulation of Multi-Vehicle Signaling System with Matlab / Simulink and Design of Train Timetable

Abstract

The design of the signal system is very important in order to achieve feasibility values ​​and to provide adequate performance in rail transportation systems. The signaling system is designed to comply with the highest safety requirements such as SIL4 (Safety Integrity Level) according to European standard CENELEC. It is carried out with an uninterrupted exchange of information between the on-board system and the equipment to guide the operations for the enterprise. When designing the signaling system, the life of the system is determined as minimum 30 years. Signaling system is used to control train movement and to ensure train safety. In this study, simulation of multi-vehicle signalization system with the help of matlab / simulink and the design of the train timetable were performed. For the study, the results obtained by simulating the signal system using the data of a rail system line were evaluated on the graphs. With the help of simulation, train overlap analysis is performed together with the frequency of travel analysis to increase the performance and efficiency of the signal system.

Matlab/Simulink Yardımıyla Çok-Araçlı Sinyalizasyon Sisteminin Simülasyonu ve Tren Zaman Çizelgesinin Tasarımı

Abstract

Raylı ulaşım sistemlerinde fizibilite değerlerinin yakalanabilmesi ve yeterli performansın sağlanabilmesi açısından sinyal sisteminin tasarımı çok önemlidir. Sinyalizasyon sistemi, Avrupa standardı CENELEC uyarınca SIL4 (Emniyet Bütünlük Düzeyi) gibi en yüksek emniyet gereklilikleriyle uyumlu olacak şekilde dizayn edilmektedir. İşletme için operasyonların yönlendirilmesi amacıyla araç üstü sistem ile donanımlar arasında kesintisiz bir bilgi alışverişiyle gerçekleştirilir. Sinyalizasyon sistemi tasarlanırken sistemin ömrü minimum 30 yıl olarak belirlenmektedir. Sinyalizasyon sistemi tren hareketini kontrol etmek, tren güvenliğini sağlamak için kullanılmaktadır. Bu çalışmada matlab/simulink yardımıyla çok-araçlı sinyalizasyon sisteminin simülasyonu ve tren zaman çizelgesinin tasarımı yapılmıştır. Çalışma için bir raylı sistem hattına ait veriler kullanılarak sinyal sisteminin benzetimi yapılarak elde edilen sonuçlar grafikler üzerinden değerlendirilmiştir. Benzetim yardımıyla tren çakışma analizi sefer sıklığı analizi ile birlikte yapılarak sinyal sisteminin performansının ve verimliliğinin arttırılması hedeflenmiştir.
