Advantages Of The Solution:
CBTC+ fixed block-based ATP + ATO solution is designed mainly for mass rail transit with short train tracking interval, high traffic density and high RAMS requirements.
Moving block, large-capacity train-track two-way information transmission.
Two-level backup mode (fixed block-based +interlocking).
Details Of The Solution:
The CBTC signaling system with LCF-300 ATP/ATO as the core is the automatic train control system based on radio communication, and it can realize moving block, which is the most advanced train safety control technology with minimum headway. This system is a train control system designed in accordance with the international IEEE1474 standards and developed to implement the whole-process risk control in accordance with the safety design and assessment standards for vital systems.The system succeeds in solving such key technical problems as high-precision and high-safety train positioning, large-capacity train-track bidirectional safe data transmission, safety protection and control of high-density train tracking operation and high-precision automatic train driving. On the other hand, the CBTC system is systematic, network-based, informatized and intelligent. The function of the system is more powerful, the structure is more complex, and is more closely related to such sectors as the lines, transport organizations and vehicles. It can meet the requirements for growing passenger traffic and ever-increasing requirements for transport. It is currently regard as the sustainable signaling system for sustainable development.The CBTC signaling system with LCF-300 ATP/ATO as the core has two-level backup mode (fixed block-based and interlocking), so the availability of the system is significantly improved.
