ERTMS/ETCS LEVEL 1/2 Solution

System Introduction

European Train Control System (ETCS) Level 2 is a radio-based train control system with an underlying signalling system. It is based on continuous bi-directional wireless data communication between the Radio Block Centre (RBC) and the trains, with balises mainly for position referencing. HollySys has obtained Baseline-3 (B3R2) TSI certification for the RBC and the on-board train control system. The ERTMS/ETCS Level 2 solution offered by HollySys includes the Centralised Traffic Control System, the Intelligent Maintenance System and ETCS Level 2. It can be equipped with distributed Computer Based Interlocking or Solid Static Interlocking systems. In addition to conventional solutions, the system provides remote control of trackside equipment and intelligent maintenance of signalling equipment.

Features

Continuous Control
- Train speed and the target-distance are controlled through onboard-trackside bi-directional transmissions of real-time data.
Interoperability
- Enables the interoperability between ETCS level 2 railway lines and operation in degrade level.
Flexible Configuration
- The system can be flexibly customised to match existing national systems and user requirements.Trackside control equipment can be flexibly deployed indoors or outdoors, wired or wireless, depending on site conditions. Lineside signals and object controllers are optional and can be suppressed if necessary.
Integration
- The Center system integrates the functions of dispatching and maintenance. The trackside object controller equipment integrates the functions of control and acquisition, it is also equipped with both wired and wireless modules.
