Advantages Of The Solution:
The fixed block-based ATP+ ATO system solution is designed for mass rail transit with short train tracking interval, high traffic density and high RAMS requirements. At the same time, this scheme can also be used as the backup mode when the continuous train-ground communication equipment fails, which makes the train unable to operate under the CBTC level.
Eurobalise intermittent dada transmission.
Interlocking backup mode.
Automatic train operation (ATO).
Details Of The Scheme:
As the key component, the euro-balise can store the necessary data including train speed supervision and other operating functions in the fixed block-based ATP+ATO system., The variable data balise, which is placed beside the signal, is used for transmitting movement authority to the train.Besides the basic ATP function, the fixed block-based ATP + ATO system can also realize such functions as coordination between the train door and the safety door, departure protection in the case of red light.
On-board ATP equipment.
On-board ATO equipment.
On-board radio communication.
Wayside radio communication.
Axle counters and wayside signals.
Advantages Of The Scheme:
Integrated design: It includes two-level control mode (fixed block-based control and interlocking control), and implements integrated design and verification according to the operation control and management of different marshaled trains and the demand for operation in phases and sections.
High requirement consistency: It is developed strictly following general international requirements and safety standards.
It can realize fixed block control based on intermittent transmission, and meet the operating requirements of different systems through flexible layout of wayside equipment.
Automatically establish or switch operation mode.
It has passed international independent safety assessment.
Two-level train control and interlocking backup mode.
It can realize coordination between the train door and the safety door under the fixed block-based level.
It can realize wrong train departure protection in the case of red light under the fixed block-based level.
Standard Indexes Of The Solution:
The on-board ATP equipment adopts “2oo3” safety computer structure and meets the safety requirements for SIL4.
The ATO control accuracy is within ±25 cm.
The overall system product has reached the requirement of safe design up to 200km/h.
