Measuring Services & Data Analysis

MERMEC Group expertise in Measuring Service is made available to customers with the aim of implementing a complete diagnostic campaign based on integrated measures, in order to get all relevant information on the railway infrastructure.

Both general and specific data are detected in order to correlate these information with the infrastructure state: detailed reports containing all results are realized  to allow a specific data analysis and management, and a related maintenance planning.

Reports include:

• list of interventions to be performed
• exact position of interventions on the infrastructure
• timing of interventions

MERMEC Group is able to offer Measuring Services to the customers using:

• Integrated Hi-Rail Measuring Vehicles
• Track Geometry Measurement Vehicles 
• Ad-hoc bundle of measuring systems 

Usually the above mentioned vehicles and systems are propriety of MERMEC Group, but measuring service can be performed also using customer’s existing vehicles set with MERMEC Group rented systems.

• Visualisation of measurements by "survey"
• Generation of defects from measurements wit a set of configuaration rules
• Comparison of the localisation of the survey with the localisation of the other surveys
• Comparison of a survey with measurements from different surveys
• Possibility to "modify/update" the localisation information
• Validate measurements by setting a level of validity or reliability to each measurements
• Setting validation flags associated with the survey checked
