Teknis: WCM System Output

Wheel Condition Monitor (WCM)

SYSTEM OUTPUT

WCM integrates comprehensive data analysis with a powerful database application and a complete incident management system. The system supports a network or dialup connection direct to maintenance depot or other PCs running the database. This gives repairers immediate access to all the data they need for the most efficient maintenance scheduling.

Just by using the automatically printed reports a maintenance team can know exactly which wheel (or wheels) require attention and the type of damage to expect. By referring to WCM db they can look at the history of the damaged wheels to see how a defect has changed over time. For example, a wheel that shows a progressively worsening defect can indicate a hidden growing defect.

The system can automatically raise an 'incident' in case of significant wheel damage, loading problems or other user-defined criteria. Incidents are records that require actioning. Once an incident has been dealt with according to operational procedures it is explicitly closed. An incident can be edited to include comments or instructions and so form a record of response undertaken.

The database application runs on any Windows Workstation.

The database application is made up of three elements. All three can coexist in one database or can be used in separate databases. The mode of operation is based on user type determined at login.

Real-time data input and processing
Built-in user based and scheduled inquiry, report and analytical functions
Data warehouse for export in custom format or servicing SQL enquiries.

Functions are built in to enable transfer from the master to archives. Typically the inquiry and data warehouse functions are supported by the LAN based archive.

Real-time data input

The real-time data input is a proprietary element of the database. This element performs the functions required to complete the processing on the partially processed sensor data from the remote sites. User parameters are used in the final stages to translate these into user defined units and thresholds. This front end also inputs sensor data from third party equipment such as HBD/HWD, WID Tbogi Angle-of-Attack and some wheel profile equipment.

This component of the database application has a re-processing function.

For modelling purposes and to enable signal processing changes (such as alarm settings or defect-recognition). This is possible because all sensor data is stored in the database as received from the remote equipment.
