Diagnostic tools to diagnose and operate a signaling system
Enhanced diagnostic tools that extract performance data from the CBTC system to identify anamolies performance problems in the system.
The additional diagnostic tools needed to diagnose and operate a CBTC system
Digitalization, big data & analytics
Sub-systems and devices are required to generate remote diagnostic data.
The target of the diagnostic data is to identify hardware and software failures that are diagnosed to the board or component level.
The goal of this type of diagnostics is for quick repair of the device.
Wayside sub-systems are connected by a network and diagnostic data is collected remotely at a central location
3
Conventional signaling components can, if outfitted, record information on operation of wayside devices (point machines, signals, CBI, etc.)
Data can be collected from wayside devices and sub-systems and sent to a central location to monitor wayside object to predict and identify failures

Utilize predictive maintenance to reduce life cycle costs and maximize asset availability By monitoring the switch machines’ movement performance we can predict
and support our customers to avoid failures & replacements
Switch failures can be predicted by monitoring
movement time and setting warning thresholds
Failure reports are cross- checked with data patterns
to improve predictions

Onboard controllers can record events and runtime data that can be offloaded manually
Vehicle manufactures provide vehicle data recorders and diagnostics on vehicle performance that either is offloaded manually or a seperate communication system is provided to download the information

CBI, ATO). Provides for low level
system Monitoring. Live and recorded playback
of events. This is a great tool for post
analysis of operation.

CBTC provides a continuous supervision of system operation
Functions never seen before are now subject to careful analysis
Analysis of the new data and functions can identify key issues and improvement areas even those not directly related to CBTC system
Working areas:
• Operational procedures
• Maintenance procedures
Many disturbances and operational problems are due to: Reliability and availability issues Undetected rolling stock failures causing performance degradation Unexpected interactions between system and end users Small disturbances that add up to a significant effect
Combine onboard and wayside data to reveal operational disturbances and problems.

Abnormal dwell times Linked usually to door issues
CBTC analysis can help to identify an incorrect driver action, such as quick changes in master controller: forward reverse that blocked train traction. Which could cause failure events lasting up to 20 minutes.
Central operators will now be able to help drivers solve the issue
Retrofit action can be launched by customer maintenance to avoid this effect
