CBTC

Communication Based Train Control System

Product Introduction

CBTC (full name: communication-based train control system) realizes information exchange between trains and station/control center and controls the train operation utilizing onboard equipment and trackside communication equipment through advanced communication, computer calculation and the moving block of continuous control and monitoring on train operation.

Characteristics

It has been widely applied in the field of urban rail transit signal systems in recent years due to the advantages such as small departure intervals and high safety and reliability.

Moreover, CBTC is also a sustainable and cutting-edge train operation control technology and lays a basis for the new generation of technologies such as FAO and I-CBTC. TCT’s CBTC signal system solution is composed of seven subsystems with ATP/ATO as the core, including vehicle on board controller (VOBC), zone controller (ZC), data storage unit (DSU), data communication system (DCS), automatic train supervision system (ATS), computer interlock system (CI) and maintenance support system (MSS).

Case

As the major project of the “11th Five-Year Plan” national sci-tech support plan “The core technology CBTC development and demonstration project of Beijing Rail Transit”, Beijing Subway YIZHUANG Line was put into operation officially on December 30, 2010, with the total operation time of 33min, the full length of 23.23km and 14 stations (6 underground stations and 8 elevated stations).

As the core equipment supplier of YIZHUANG Line signalling system, TCT plays a leading role in technology and takes full responsibility in system design, core technology, safety management, system integration and debugging, field motor car commissioning, and test during trial operation.Besides, TCT has realized all functions of ATC such as moving block of train operation, automatic train protection, ATO, ATS, interlock/linkage of train and safety door and unmanned automatic turn back since the operation of lines.
