What is Condition Based Maintenance?
Condition Based Maintenance is a maintenance strategy to monitor the real-time condition of tracks and trains. This results in large data sets that give away key information for efficiency gains.
How it saves you money:
- Do what is needed, not what is scheduled
- Do it before it breaks
- Do only what is necessary
Experts estimate that condition-based maintenance can lead to an overall reduction of at least 10 to 15% in maintenance costs.
Harvesting, battery or train power?
There are a number of powering technologies when it comes to Condition Based Maintenance in the railway industry.
The four main options are:
- Thermal Harvesting
- Battery Power
- Vibration Harvesting
- Wired Power
The power source you choose affects the quantity and quality of the data available for collection, analysis and onward transmission.
- Very Low Energy amounts
- Heat source needed
- Doesn’t allow permanent operation
- Good energy buffer
- Must be replaced
- Degrades over time
- Very low energy amounts
- Tuned vibration source not realistic in rail use
- Robustness issues
- Doesn’t allow continuous monitoring
- Permanent operation
- Requires cabling
- Higher initial cost
