Infrastructure
Worldwide, POSS® monitors a diverse and varied range of railway infrastructure objects. The system provides railway managers and maintenance contractors with the right information to prevent failures. Points, track-circuit current flows and level crossings are particularly sensitive to failures.
Points
The performance capability of a point machine is directly related to the amount of power needed for the engine to switch points. Deviations in current consumption indicate a potential problem. The measuring units monitor current, capacity and the phase angle making it possible to maintain a detailed picture of the errors. The complete galvanic separation in operating both DC points (direct current) and AC points (alternating current) is a characteristic feature. POSS® is not connected electrically to the signalling system ruling out problems related to access. Installation is quick and easy, without requiring any track decommissioning.
Monitoring point heating with POSS
Many point switches are heated during winter to prevent them from freezing in wintry weather. The point switches may yet freeze when the point heating system fails, which will lead to disruption of the train service. Strukton Systems has developed a monitoring solution for point heating systems to prevent this kinds of problems. This solution is based on the permanent monitoring of the point temperature, which enables railway managers and contractors to see in real time whether a point heating system functions well. This prevents the freezing of points. Click here for more information about monitoring point heating with POSS®.
Track-circuit current flows
Measuring the current of the track relay provides two sources of information: the quality of the track-circuit and the quality of the axle shunt. The latter parameter is becoming more important due to the increase of light rail rolling stock.
Level crossings
POSS® guarantees the reliable and safe operation of level crossings based on the following applications:
- Current measurement. Monitoring barrier motor overload in the event of deep snow, freezing or vandalism.
- Event logging. Registering relay status as a black box function, in identifying liability in relation to incidents.
- Intelligent video monitoring. Cameras featuring image recognition check the time it takes for the barriers to close, the operation of the warning lights and the comprehensiveness of the level crossing. Statistics of passing traffic and trains are also recorded.
Other applications
POSS® can also be installed easily on a temporary basis to resolve incidental problems. For this purpose we use a mobile POSS® device, the MobiPOSS®. Additionally, POSS® is ideal for measuring earth faults, axle counters, compensation joints, rail temperature, rail tension, train detection, weather conditions, points heating and electrical systems in substations.
