Train Control Center(LKD2-KA)

LKD2-KA is a train control center system independently developed by Casco and can be applied to stations, relay stations, block posts and non-distribution statins in CTCS-2和CTCS-3 high-speed railways as well as CTCS-0 stations connected to CTCS-2 railways and C2+ATO intercity railways. Based on 2oo2×2 hardware redundant platform, LKD2-KA utilizes NISAL, BIT and other safety technologies and adds independent fail-safe check module to ensure 2oo2×2 comparison when every CPU calculation module is sound and reliable, which makes it more safe than common hardware redundant platform. LKD2-KA has won SIL4 safety certification by international third-party authority. In July 2014, the system received administrative licensing from National Railway Administration. In January 2015, it passed the technical review by China Railway Corporation and got railway product certificate issued by China Railway Test & Certification Centre.

System Advantages

  • Independent safety validation system VPS is added on the basis of “2oo2”, double-break stable output, double-break collection, NISAL and BIT technologies to ensure system safety.
  • The system passed SIL4 safety certification by independent international third party.
  • With multi-redundant structure, if a single system fails, it can switch to the other without affecting the operation.
  • The dual redundant network guarantees normal communication as it can turn to sound network when single net failure happens.
  • LKD2-KA uses independent computer power supply protection and partitioned filtering, so that the system has great lightening protection and anti-interference capabilities.
  • On the principle of software and data separation, LKD2-KA can realize the upgrade of software or data alone without affecting the existing one, which greatly improves the maintenance efficiency and reduces the project impact.
  • The software uses UML design language and modular design, making it more readable and expandable.
  • With electronic guide diagnostic function, LKD2-KA can record every message in the interaction and makes it easy for maintenance and diagnosis.
  • The system is provided with the function of online version validation to achieve process tracking and version management of system design.
  • Every hardware board is pluggable while considering the operability in design.
  • Casco has specialized customer service department to offer maintenance support the first time.

Case Study
