Advances in Communications-Based Train Control Systems by F. Richard Yu

By F. Richard Yu

With fast inhabitants explosion, enhancing rail transit velocity and potential is strongly fascinating worldwide. Communication-based educate regulate (CBTC) is an automatic educate keep watch over method utilizing excessive skill bidirectional train–ground communications to make sure the secure operation of rail automobiles. This ebook offers the newest advances in CBTC study. The contributed chapters from prime specialists within the box disguise assorted points of modelling, research, layout, trying out, administration, deployment, and optimization of CBTC systems.

Advances in Communications-Based teach regulate Systems starts off with the history and evolution of teach signaling/train keep an eye on structures. It introduces the most gains and structure of CBTC platforms and describes present demanding situations and winning implementations all over the world. next contributed chapters speak about such key examine parts as

  • Nondestructive checking out options that may be hired to examine rails and fastening parts
  • New instant channel modelling recommendations for underground tunnels and viaducts
  • Advanced instant communique platforms to enhance CBTC verbal exchange availability
  • Schemes to combine teach keep an eye on and train-ground communications by way of modelling the regulate approach of a gaggle of trains in CBTC as a networked keep watch over system
  • Use of cognitive keep an eye on to enhance educate keep watch over functionality, contemplating either train–ground conversation and teach control

The booklet contains many aiding illustrations and tables in addition to a important set of references on the finish of every bankruptcy. With this e-book, researchers and practitioners might be well-equipped to improve the examine and improvement during this very important field.

Sample text

It is composed of four subsystems: ◾ Carborne Controller (CC). The CC, also called OnBoard Controller Unit (OBCU), is located on board the train. It is responsible for determining the train speed, the train location, and the enforcement of the speed limit based on the movement authority limit (MAL). ◾ Zone controller (ZC). The ZCs are located in the technical rooms. They are responsible for calculating and providing the MAL to the CC based on the information received from the trains and from other subsystems such as the interlocking.

Where track access is very limited, the goal of this test is to prepare for functional testing, which involves more resources such as test personnel and trains. 2 Integration Tests: External to CBTC For hard-wired external interfaces to the CBTC, all inputs and outputs are tested during this integration phase. The functional part is left aside as much as possible to facilitate testing. For instance, all track circuits and switch positions are verified. External interface tests can be performed independently from the localization and the radio tests.

1 Rolling Stock Characterization Tests Though it is not part of the verification and validation, the characteristics of rolling stock should be verified and/or determined through field activities by the CBTC suppliers. The transit agency and rolling stock manufacturer decide based on tests and other considerations what is the guaranteed emergency brake rate and what is the maximum acceleration rate on leveled track. However, it is not sufficient for the CBTC supplier to tune its train model used for proper ATO.
