Course detail
Technical Diagnostics I
FSI-XT1 Acad. year: 2019/2020 Summer semester
The course is focused on modern knowledge of technical diagnostics of machines and equipment. Emphasis is placed on the theoretical knowledge of technical diagnostics, such as the integration of technical diagnostics into product quality, the clarification and description of diagnostic systems, the analysis of diagnostic models, diagnostic signals and the distribution of technical diagnostics according to various aspects. Subsequently, attention is focused on selected diagnostic methods, such as thermodiagnostics, water level diagnostics and flow diagnostics. There is always an emphasis on using individual diagnostics to assess the condition of a technical object. Selected and discussed methods are important for understanding multi-parameter diagnostics. The remaining most important methods of multiparametric technical diagnostics are explained in the following subject.
The course is supplemented with an exercise where the most important topics are properly practiced. There is also a discussion on the results obtained and conclusions in the exercises.
Technical Diagnostics I is followed by Technical Diagnostics II, which is a continuation of description and analysis of other diagnostic methods suitable for assessment of the state of technical objects. By studying both subjects, students will acquire comprehensive knowledge of multiparametric diagnostics of machines and equipment. The findings are also based on the content of the Industry 4.0 initiative and Maintenance 4.0.

Learning outcomes of the course unit
A student acquires comprehensive and complex knowledge of the diagnostics which can apply in industrial mechanical/electrical engineering practice to solve different problems related to the aforementioned topics.
Prerequisites
Knowledge of mathematics and physics on the level of the bachelor studies completed so far is assumed.
Planned learning activities and teaching methods
The subject consists of lectures and laboratory. According to the possibility of teaching can be organized lectures for students by practitioners and excursions to companies focused on activities related to the course content.
Assesment methods and criteria linked to learning outcomes
The subject consists of lectures and tutorials. Exercises are required.
The tutorial is completed with the credit (granted in the 13th teaching weekend). To gain the credit, 100% attendance, student’s activity in tutorials and the protocols processed from all laboratory exercises and approved by the teacher are required. The examination consists from a written test, and the student‘s maximum scoring rate can be up to 100. The evaluation of test results is given by the classification scale according to ECTS.
Aims
The objective of the subject is to acquire the theoretical and practical knowledge of the diagnostics of technical systems.
Specification of controlled education, way of implementation and compensation for absences
The student attendance is checked in tutorials (presence and activity). The 100% participation in tutorials is required, and in case of absence, the student will be obliged to compensate, the alternative attendance will be specified by the lecturer.
