Examples of switch measurement results obtained with the TEE trolley
Switch condition assessment can be done by using measurement data for its characteristic points, specified in the pertinent regulations. However, real life experience calls for more detailed information - that can be obtained by continuous measurement of the switch geometrical parameters as switch is a track. It happens that a switch - apparantly in a good shape - is no longer considered as such when its geometry is measured in more detail - every ca 30 mm. The plots below show the continuous measurement results of a switch. Please note the ribbon plot at the screen bottom - it is a summary switch geometry assessment made automatically by the system. The user is free to select geometrical parameters and their tolerances that will be taken into account for the quality evaluation. Tolerances for any parameter may vary for different switch zones, such detailed specifications can be named and saved by the user. Two screns below show measurement results for two different paths through the switch.
Example:
The main goal of the TEE system software has been to assist the system operator in generating the measurement reports with the assessment of the switch quality level. Switch quality is evaluated using the synthetic switch quality coefficients in a 1-10 scale, and presented in concise Measurement Reports (PDF file - 158 KB).
