Automatic Train Protection (ATP)
Tram and Light Rail Safety System
This system ensures safe speeds and intersection navigation using real-time data from RFID readers and beacons. It includes Automatic Speed Control and Crossroad Overpassing Control, enhancing safety and efficiency in urban environments.
As cities grow and traffic becomes denser, safeguarding trams and light rail vehicles (LRVs) is crucial. These modes of transport share urban streets with pedestrians, cars, and buses, requiring an adaptive signalling system for safe mobility. The Automatic Train Protection (ATP) system integrates Automatic Speed Control and Crossroad Overpassing Control to manage tram speed and intersections in real-time. Utilizing the MOL81 1354 onboard reader and OMR81C tag as a trackside beacon, trams adjust speeds according to infrastructure data. The system offers universal compatibility, simple installation, all-weather reliability, and advanced technology to enhance safe, efficient urban tram operations.
The Automatic Train Protection (ATP) system integrates two critical functions:
– Automatic Speed Control: Ensuring trams maintain safe speeds in varying urban conditions.
– Crossroad Overpassing Control: Safeguarding intersections where tram paths intersect with other traffic.
These functionalities operate in real time with high availability and are essential for smooth and secure operation of trams in the bustling urban landscape.
Automatic Speed Control
The Automatic Speed Control System is designed to enhance train safety and efficiency. It involves two key components: the Onboard ATP MOL81 1354 Reader, an Automatic Train Protection RFID Reader installed on the train, and the Trackside OMR81C Commutable Beacon, positioned along the track.
As a train travels, it automatically adjusts its speed to comply with limits communicated by the infrastructure. When the train passes the OMR81C beacon, the onboard ATP MOL81 1354 Reader receives crucial information about speed limit and location. This data is then relayed to the train’s computer for processing, ensuring the train complies to the set speed limits.
Crossroad overpassing control
Additionally, the system plays a crucial role in crossroad overpassing scenarios. The trackside controller can use it to grant or deny train passage (indicated by green or red lights) at crossings, enhancing safety at these critical points.
Overall, this system represents a significant step forward in railway management, offering a blend of advanced technology and user-friendly features to ensure safe and efficient train operations.
The MOL81 1354 Reader is equipped with sophisticated technology. It transmits raw encoded data using a unidirectional differential output RS422 Data Tx. This system is designed for simplicity and reliability, without internal decoding, software processing or storing of the beacon’s identification code. The reader includes a self-test feature for its 6.78MHz receiver, which can be activated through a specific input. It also signals its operational status of the 125 kHz transmitter through a digital output, indicating the proper functioning.
The OMR81C Beacon is versatile, capable of handling up to three different speed control references and as well the location reference. These can be selected and adjusted by the trackside controller to reflect the current condition.
Solution benefits:
- Universal Compatibility: The system is adaptable to any vehicle or trackside infrastructure, allowing versatile use across different civil works and urban environments.
- Effortless Installation: It is designed for easy setup, requiring no complex configuration, making installation straightforward and hassle-free.
- All-Weather Reliability: The system operates consistently in various weather conditions, ensuring dependable performance even in challenging environments.
- Compliance Excellence: Fully compliant with European and SNCF STME 001 Operator Standards, ensuring it meets rigorous safety and performance requirements.
- Advanced HF Technology: The system uses magnetic field inductive coupling for precise, selective protection, ensuring accurate and focused safety measures for each train.
