HS-IM High Speed Infrastructure Monitoring
Combined axle-box acceleration, microphones and high quality D-GPS railway infrastructure monitoring system.
Suitable to record a wide range of parameters including rail corrugation and roughness, squats and studs, welded joint degradation and quality of the turnout components. Suitable for mounting on in-service trains.
Product description:
The HS-IM is a multifunctional measurement system combining up to 16 sensors: X Y Z axle box accelerometers and microphones, with accurate 10cm positioning on the rails/track. The data, simultaneous captured at 20kHz is on train processed to standard or customer defined parameters, usable, not only for track maintenance, but also W/R noise emission differences. It goes beyond the standard rail roughness (1 50cm range) towards detection of rail/track defect in an early stage. Once the fully automated system is installed, no on train manipulation is needed. The system can be accessed and followed by sending/receiving SMS messages or directly accessed by remote desktop. Data is transmitted from the train to your desktop/database by automated 4G/5G or Wi-Fi data transmission.
HS-IM
Applications:
- Monitoring of overall rail quality
- Rail roughness measurements (1/3 octave wavelengths 1cm – 50cm)
- Early stage detection of rail defects (squats, welds, peeling)
- Relation between rail roughness and noise emission
- Influence of track components to noise emission (quality/damping of rail pads)
- Monitoring of rail joint condition and degradation
- Monitoring of condition and degradation of components in turnouts
Main characteristics:
- Measurements that are highly accurate and repeatable
- Relatively simple installation and setup
- Fully automated data logging, processing and data transfer
- Suitable for any track gauge
- Extensive product support
