With condition monitoring it is possible to enhance the usage of equipment, lengthen operating time and increase safety. The applications of internet of things allows equipment real time condition monitoring. Data collecting and editing produces information about the condition of the equipment to support decision making. The purpose of this thesis is to answer the research question \u201chow sensor data can be utilized in locomotive condition monitoring and dispatching?\u201d. The thesis includes a literature review and an empirical part which was carried out as a qualitative case study. The current system for condition monitoring was dis-covered useful. The challenges in the current state were related to end user training and involving in system specification, finding key information in big data, and diverse equipment regarding age and technical implementation. Potential benefits of condition monitoring regarding fleet management were related to monitoring of actual performance and finding out intermittent faults recurring defects. For operative side, the benefits were related to achieving a quick snapshot about the equipment condition and parking track planning based on the equipment condition. Major factor about a possible implementation was defining different user groups and their needs. In day of operations, the collected data should be mostly filtered and visually represented condition monitoring data. On the fleet management side, event data and the following of time series were more relevant. Condition based maintenance was seen as a possible strategy regarding the optimization of maintenance program for certain equipment types, based on actual usage. Also, the condition monitoring data was experienced useful concerning locomotive dispatching and forecasting equipment malfunctions. As to data analysis, a key thing was utilizing track data together with equipment data. The differences in equipment performing similar tasks could also be included in the analysis. Separating and comparing different subsystems in the equipment could be used in the analysis, and to exclude false alarms. Condition monitoring data could also be utilized in comparison of equipment components from different manufacturers.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2020-10-16T06:22:48Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2020-10-16T06:22:48Z (GMT).
