Aims
Aims
Unplanned and planned non-availability of the track caused by failures or restrictions are cost-drivers in the networks.
A prediction of failures allows an optimisation of the instant of time, where the
work is economical in a larger part of the track. Larger maintenance sections reduce the costs and provide usually a better quality !!!
Switches are most critical devices in the network concerning availability and costs.
A reduction of failures are direct noticeable by the passenger or the logistic company.

Solutions
Solutions
Monitoring of track alignment by regular sheduled trains during operation to get „Online“-Information of the track. On this basis a prognosis of the deterioration of single faults is possible and a maintenance planning for the line is more economical.
Monitoring and inspection of switches will give an individual information about the
„Health“ of a switch. Maintenance intervention before any faults are possible, maintenance staff will be equipped with the spare-parts needed. Traffic interruption caused by switches will be reduced.

Advantages of ISM
Advantages Reduction of service breakdown and delays by early detection of defects
Measured data are automatically stored in a maintenance database
Prediction of defect development (more frequently measurements)
Early maintenance planning due to defect/failure prediction (Single defect tamping vs. line tamping)
Verify the quality of repair efforts (close control loop)
Measurement is a “by-product (spin-off) of train operation”
Improvement of maintenance management Reduction of costs (LCC)
From “Find and Fix” to “Predict and Prevent”
High Availability of the Freight-Backbones of the ports (Target of FP 7 !)

Processing of the acc.-data
Quelle: DLR
Processing of the acceleration data To gain the vertical alignment from the acceleration data, a double integration has
to be carried out. Algorithms were applied to minimize sensor errors. Still, different measurement runs could not easily be compared, see the Fig. left side.

Switches & Crossings
SP 3.2 Monitoring & intelligent self-inspection of switches
Switch inspection with special staff for the signalling and the track part causes a lot of logistic and economical effort
Inspections are carried out in fixed time periods
– The condition of the individual switch is not respected
– Sudden defects will be undetected until the next inspection or produced a failure
Prediction of development of defects is difficult
Monitoring is different than Self-Inspecting

Modular Self-Inspecting Infrastructure – Switches
Condition monitoring Automatic inspection
Focussed on inspecting the asset according to inspection standards and it can: - identify the assets that do not meet the standards - carry out inspections specified in inspection standards - carry out the inspections in a way that satisfies the inspection requirements (e.g. precision of measurement)
Orientated on the fault and it can do: - fault detection: a system is able to detect a fault which is happening - fault diagnosis: a system is able to diagnose the fault - fault prediction: the system is able the predict a fault a certain amount of time before it will happen

Modular Self-Inspecting Infrastructure – Switches
Condition monitoring Automatic inspection
1. Measure parameters specified by inspection standards.
2. Parameters must be measured must be in line with the standards.
3. The drive is to eliminate the need for maintenance personnel to inspect switches in person.
1. Measures parameters that reveal faults in the system.
2. Analyse the data and identify the faults or predict potential faults.
3. Develop a cost effective system. The drive is to use the smallest number of sensors to identify the largest number of faults.

Maintenance task definition
The MMI is a “task management system”. The level of data managed by the MMI is a maintenance task. From ISO13374-1:2003 (Condition monitoring and diagnostics of machines — Data processing, communication and presentation — Part 1: General guidelines) the level of data for a maintenance task is defined as a recommended action.

RailML data standard
www.railml.org Since 2001: The railML.org Initiative was founded against the background of the
chronic difficulty of connecting different railway IT applications. Its main objective is to enable heterogeneous railway applications to
communicate with each other. Today, the connection of various railway software packages is beset with
problems. The purpose of the railML.org Initiative has been to find, discuss and present systematic, XML-based solutions for simplified data exchange between railway applications.
First step in european standardisation for maintenance IT-tools MERMEC has already provided lists of standard defects and standard
measurements.

RailML data standard
State of the art in AUTOMAIN The RailML schema was agreed by all partners The level of data is “the maintenance task”. Every demonstrator has to decide
the way of communication: The monitoring inspection systems must send a maintenance task to the MMI The monitoring inspection systems send a failure to the MMI, and a “translation table”
validated by the maintenance will match the tasks in relation to the failure produced. Every system must send a message to confirm the system is alive
A draft of a XML schema exists to understand The RailML standard will be a data schema file (XSD file). When it is mature
(approved by demonstration), it will be proposed to the official RailML organization.

Map for Tasks
The assets have colours and description for the flag: No flag if no task RED Flag: Needing corrective maintenance. ORANGE Flag: Needing preventative maintenance
For the scheduled maintenance, the asset will be “orange” when it’s time to do it and red when it’s too late. For the conditional maintenance, the asset will be “orange” when it appears (alarm from a system, expert
report...)
