Tiivistelmä (eng): | The purpose of this thesis is to study different kinds of control system based maintenance tasks on a Wärtsilä diesel/gas engine and to investigate how such tasks could be semi-automated. The results of the study were used to implement a prototype, which is able to import and execute these semi-automated tasks. A typical task is defined as a procedure that assists the operator in performing local and discrete service work. Four main categories of tasks were identified in the maintenance information system hierarchy: instructions, tests, tunings and analyses. The study further acknowledges similar tasks throughout the extended product life cycle. The result discerns a wide area of different procedures with varying development requirements. The study argues, however, that if a flexible tool were available to handle all these tasks, it could offer excellent comprehensive testing, tuning and analysis opportunities for both customers and in-house engineers at every stage in the product life cycle. This range of tasks was used as a basis for the prototype tool. The technical study reviews different software component techniques and tools for task development. COM techniques are covered in depth, along with high-level development means such as MATLAB, script languages and XML techniques. The prototype solution turned out to be based, somewhat surprisingly, on the Internet Explorer web browser control used in a local environment. The implemented prototype offers a programming interface to the control system for task development, with the web control used as an embedded execution host. The developed prototype proved itself to be a cost-effective and flexible solution for the tasks in question. The prototype fulfils its stated requirements, and is hence recommended for official implementation. |
