2.5.18 Run cycle mode
Through its capabilities in Event Capture (
) the IMx-16Plus (IMx-Rail) supports
the @ptitude Observer RailMo (Rail Track Monitoring) feature. A train mounted IMx-
Rail uses accelerometers on two analogue channels to capture left and right (rail)
vibration and two tacho signals to determine the speed of the train, estimate the
distance travelled and infer its direction of travel.
The two vibration points are assigned as part of a Run cycle group, so that whilst the
train is moving the vibration (sample level) data can be collected for rail condition
analysis. By repeatedly collecting direction sensitive track vibration data and pattern
matching this to the track infrastructure, the software can readily identify anomalies
for inspection and corrective action. For further information on RailMo, refer to the
SKF @ptitude Observer User Manual, Revision Q or later.
2.6 Hardware Maintenance
The IMx-16Plus hardware, i.e. IMx-16Plus device and its associated sensors, are
virtually maintenance free, though a yearly inspection of all installed equipment is
advised.
The IMx-16Plus device does not need to be opened for hardware maintenance or
inspection, in case of suspected hardware failure; replace the faulty device (unit
replacement).
Good practice is use the IMx Manager app to generate and compare annual SAT
(Site Acceptance Test) reports.
2.6.1 Performance over Time
No significant performance degradation over time, is expected for the IMx-16Plus
hardware.
2.7 Mobile data/Wi-Fi antenna (optional)
This combined mobile / Wi-Fi antenna is suitable for mounting on/through an outer
enclosure or cabinet.
It has a circular footprint and the integral cable is pre-terminated in appropriate
connectors for the LTE 1, LTE 2 and Wi-Fi connections on the IMx-16Plus, top end
cap*, refer section
