Next Generation Train Control System Solution for High-Speed Railway

System Introduction

Based on HollySys continuous accumulation and innovative research in the technical fields of signalling, control, communication and computer, we have designed and developed a new generation of high-speed railway train control system, which has large transportation capacity, high comfort, high intelligence and high cost performance on the essential of safety and reliability.

The system is composed of intelligent dispatching equipment, Radio Block Center (RBC), Interlocking, on-board equipment, satellite positioning equipment, wireless communication equipment and intelligent operation and maintenance equipment, etc. It adopts moving block technology or virtual block technology which is based on wireless communication (configurable), it has the capability of multi-source fusion autonomous positioning. There is no need for block signal, track circuit or axle counter beside the track, and the balise can be optional.

Features

Safety and Reliability
- Based on the fail-safe principle, it conforms to IEEE, IEC, CENELEC standards and national standards. The core equipment such as RBC, TSRS, on-board equipment, satellite positioning system and interlock have got SIL4 safety certification, and the control equipment have proven record of reliability and fulfills intelligent diagnosis functions, which guarantees the safe and reliable operation of trains.
Moving Block Technology
- The system controls trains based on the principle of moving block. According to the real-time position reported by trains, it dynamically calculates the movement authority at the rear of the ahead train, effectively reducing the headway between trains.
Bi-Directional Wireless Communication
- The system supports wireless communication technologies such as GSM-R, LTE and 5G, and realizes bi-directional data communication between trackside equipment and on-board equipment, fulfill real time information transmission such as line data, moving authority and train position report in real time.
Multi-Source Autonomous Positioning
- On-board equipment combines various information such as satellites, balise, speed sensors and digital maps, and locates trains through multi-source fusion algorithm.
Train Integrity Check
- The on-board equipment can judge the train integrity through satellite, sensor, wind pressure monitoring and other information. It also can cooperate with train tail equipment EOT to jointly check the train integrity.
ATO Functions Support
- The system can configure ATO equipment and functions as required to realize automatic train driving.

Customer Value

System Integration

The ground facility adopts interlocking train control integrated equipment, which can realize train control functions on the ground such as movement authority, line data and interlocking control It has simplified the system composition and data flow, and reduces the occupied space of equipment.
Transport Efficiency

The system performs train tracing based on moving block, resulting in short train headway and high transport efficiency. When ATO functions is configured, automatic train driving can be realized, and transportation efficiency can be further improved.
Cost Saving

Due to the adoption of wireless communication, train independent positioning and integrated design without relying on track circuit, all-electronic design and lineside object control technology, the number of trackside equipment, the amount of cables and civil engineering required are reduced, and the high-reliability equipment is equipped with intelligent operation and maintenance functions, which effectively reduces construction costs and post-maintenance costs.
Customized Service

According to different national standards, user's needs and site conditions, customized configuration can be carried out.
