Solutions
Our solutions are able to detect anomalies occurring on the rail tracks by analyzing the energy which travels in the rails across long distances. In addition, our systems provide critical information to operators, such as the number of wagons passing a designated point of reference, speed predictions of rolling stock, the type and estimated time of arrival of rolling stock to a point of interest.
There are still a high number of accidents where the triggers are not detected in time, or at all, as can be seen on the graph below. Our solution can detect such precursors in advance and can play a role in preventing such accidents from happening.
We provide solutions and critical metrics which are currently either not provided on the market, or are inferior to our solutions in terms of their reliability, flexibility or range of detection.
Diagnostics Applications
Axle Derailment Monitoring
The Axle Derailment Monitoring application detects derailed axles on rolling stock and sends alarms to the operators once the issue is detected.
The outputs for this application are:
Axle derailment alarm
Rolling stock statistics (number of rolling stock passes observed, direction of travel)
Axle derailment severity
Rolling stock advanced statistics (number of axles, wagons, type of rolling stock, speed)
Rail Defect Monitoring
The Rail Defect Monitoring application monitors the structural integrity of the rail. It has two detection modes:
Complete rail separation
Development of cracks
The outputs for this application in the complete rail separation mode are:
Complete rail separation alarm
Estimated location of fault
Complete rail separation alarm in case of the snap of the rail caused by rail stress (no rolling stock pass needed for detection)
The outputs for this application in the crack development mode are:
Developing crack alarm
Estimated location of the crack
Severity of the crack
Estimated time until full separation
Track Obstruction Monitoring
The Track Obstruction Monitoring application detects when objects fall on the track causing a dangerous situation for any rolling stock traveling on the rail.
The outputs for this application are:
Track obstruction alarm including severity
Distance estimation of the event relative to the position of the sensors
Cause of the obstruction
Flat Wheel Detection
The Flat Wheel Detection application detects the presence, location and severity of flat wheels on any rolling stock.
The outputs for this application are:
Flat wheel detection
Severity
Location in terms of bogie and/or distance from the front part of the rolling stock
Location of the flat wheel in terms of the specific axle/wagon of the rolling stock
Intrusion Detection Application
Detects suspicious activity in the vicinity of the sensors.
The outputs for this application are:
Alerts of animal activity or human activity in the vicinity of the sensors
Detects sabotaging incidents such as drilling, cutting, etc, of the rails and cable theft
Safety Applications
rail occupancy monitoring
The outputs for this application are:
Rolling stock locaton in term of monitored segments, i.e., the system knows in what monitored segment the rolling stock is currently at
Rolling stock informaton while crossing a sensor point (direction of travel, speed, number of axles)
Exact location of rolling stock and reduced number of segments covering larger distances
Rolling Stock Monitoring
The Rolling Stock Monitoring application monitors the movements of rolling stock at a specified area and is able to predict the arrival time of the rolling stock at the installation location.
The outputs for this application are:
Location of the rolling stock with respect to the installation point (arriving, on top of the sensors, departing)
Predicted arrival time (e.g. constant warning times at level crossings)
Rolling stock statistics (number of rolling stock passes observed, direction of travel)
Support for atypical rolling stock movements, e.g. the same rolling stock moving in opposite directions on the same track
Rolling stock advanced statistics (number of axles, wagons, type of rolling stock, speed)
Rolling stock identification or tagging
Our R&D department is constantly working on the improvement and innovation of our solutions. New applications being developed include Hot Bearings Detection and Rolling Stock Weighing.
A hot bearings incident occurs when the bearings of an axle become damaged, increasing the friction, and therefore overheating the bearings. This situation could lead to fire and ultimately derailments, if not detected in time. DSRailTechs Hot bearings Detection Application locates axles with hot bearings issues on any rolling stock, and signals this incident to the operators with different severity level warnings.
Rolling stock weighing is an important topic for every infrastructure owner, overloaded wheels can lead to increased wearing of wheels and infrastructure, therefore the importance of keeping an eye on the loads imposed on every wheel of the rolling stock. DSRailTechs Rolling Stock Weighing Application measures the load on every wheel of any rolling stock, regardless of speed, informing the operators of any deviations from their set default values.
Both applications will be available in 2021. Should your company wish to take part in our trials then please contact us at trials@dsrailtech.com
