A significant part of the budget for the maintenance of point machines is destined for corrective tasks that need to be carried out after the occurrence of an error in a point machine that causes a standstill of the service. For this reason it is of great importance-of point machine monitoring.
The smart motors® monitoring system allows breakdown diagnostics. To do this, 3 devices are used in order to obtain on real time data at different levels:
Thanks to a monitoring system, which allows different degrees of investment according to the relevance of the engines, it is possible to predict breakdowns and improve the diagnosis of sudden breakdowns.
DIAGNOSING BREAKDOWNS TO IMPROVE THE SERVICE AND MAINTENANCE
Certain breakdowns are predictable. Meaning, a good continuous monitoring system, that knows the breakdown patterns, is able to identify and signal a breakdown before it takes place and negatively affects the service.
Examples of predictable breakdowns: electric motor breakdown, lack of pressure in the tank, lack of grease, problems with the anchors, water in the box, expansion of the control hammers.
FAILURE PREDICTION AND IMPROVEMENT OF AVAILABILITY
It is difficult to give a precise figure, given the great diversity of point machine and network types, but based on our data, predictable breakdowns represent around 60-70% of the annual breakdowns.
The artificial intelligence in the smart motors® solutions, called MAGI, includes a functionality that detects real tendencies among the breakdowns that are reported to the maintenance management system of the operator, with the objective of solving them before they become a serious problem.
All long-haul breakdowns with a known failure pattern can be identified before they occur. This way you will need fewer resolutions, and also less repositioning and substituting of point machines.
For certain breakdowns that can never be foreseen and thus not avoided using breakdown patterns, a monitoring system can also help to reduce impact on the service and reduces costs.
Examples of non-predictable breakdowns are: not receiving the control voltage, errors in the verification, modifications that were badly performed during inspections, obstructions on the tracks, etc.
CORRECTIVE ORIENTED
In order to use information to add value, the smart motors® solution provides a breakdown report in which the likely causes and recommended resolutions are indicated.
With the smart motors® system it is possible to provide indications for corrective measures of non-predictable breakdowns:
To sum up, the current smart motors® operation systems have proven benefits that will help your maintenance team make better management of breakdowns in needle change engines.
