OPTIMIZE YOUR RAILWAY OPERATIONS
Today's railroad services need to operate efficiently and safely, while maximizing customer experience by assuring excellent quality of service.
Rail Monitoring is becoming increasingly important in today's environment - including the capacity for Train Location, Asset Monitoring, Third Party Interference Monitoring and Fire Detection in Cable Ducts. AP Sensing's Rail Monitoring solution provides various benefits that include increased information, safety, efficiency, capacity and cost savings.
In conjunction with a track-side fiber optic cable infrastructure, AP Sensing's Distributed Acoustic Sensing (DAS) system is capable of detecting and supplying information about the exact position, speed and direction of moving trains in the network in real time. This allows intelligent automated traffic management with actively controlled and even automated train operation. It also helps to minimize delays and keep customers precisely informed. In the near future, DAS technology may enable the increased capacity of a rail network by running more trains safely at a higher density with lower distance.
Our technology supports the digitalisation of railways and helps to optimize operations. It enables preventive and predictive maintenance, minimizing unscheduled service disruptions. Our DAS system also increases safety by assuring train integrity and detecting people or falling objects on the tracks. Intrusion, vandalism and cable theft are detected and precisely located with the AP Sensing DAS.
To address the high safety standards and requirements in the railroad environment, a DAS system can successfully supplement complementary sensor technologies in a Sensor Fusion system. DAS data can be easily integrated into any centralized rail management system.
AP Sensing is the Distributed Fiber Optic Sensing (DFOS) and Distributed Acoustic Sensing (DAS) solution provider for optimizing your railroad operations. Our railway monitoring solution balances the need for train detection, asset monitoring and optimized safety.
DISTRIBUTED ACOUSTIC & TEMPERATURE SENSING
AP Sensing's Distributed Acoustic Sensing (DAS), together with our unique SmartVision™ asset visualization and data management software, gives you the ideal solution to optimize and protect your railway infrastructure. Our DAS is based on the unique 2P squared technology. It offers accurate detection and location of moving trains and Third Party Intrusion (TPI), as well as asset monitoring of both tracks and moving stocks. This helps you operate your railroad service more efficiently, while reducing investments and operational costs.
Our Distributed Temperature Sensing (DTS) offers continuous temperature monitoring along the entire fiber optic cable, e.g. along cable ducts. This enables heat/fire detection and location within cable ducts and cable trays, and inside train and metro stations. Systems are completely certified for fire detection (VdS, UL, FM, IECEx, SIL).
AP Sensing's SmartVision™ management suite shows the location, velocity and direction of trains and the condition of your assets at a glance, controlled by an easy-to-use graphical interface. It seamlessly integrates many sensors including DAS, DTS and CCTV into a single platform. Circuit layouts are mapped and color-coded to show the instantaneous changes in acoustic energy. Sections of the infrastructure can be individually defined for flexible alarm levels and types. Defined information is interfaced into higher level train management systems, enabling easy integration.
Our solutions monitor key application areas, including:
- Train location, speed, direction (also underground or in tunnels)
- Train integrity (length), number of train cars, bogies
- Track condition monitoring (cracks, joints)
- Train defect monitoring (flat wheel, brake noise)
- Intrusion detection (vandalism, cable theft)
- Natural hazards detection (rockfall, landslide, tree fall, flooding)
- Objects on track detection (work crews, persons, animals)
- Railroad crossing management (trespassers)
- Overhead contact line/Catenary flash-over detection
- Fire detection in cable ducts
- Cable overload monitoring and detection
Some of the listed features are already proven in extensive field tests, others need to be further developed and tested.
