Course detail

Industrial Systems Diagnostics

FSI-VMD Acad. year: 2025/2026 Summer semester

The course is focused on the issues of measurement (metrology), sensors and technical diagnostics. The importance of these individual scientific areas is explained and their connection and importance for current industrial practice is emphasized. The teaching of the subject is consistently based on the latest current modern knowledge.First, attention is focused on metrology, then sensors and methods for measuring physical quantities. This is extensively elaborated and justified in the lectures. Emphasis is also placed on signal analysis, causes of technical equipment failures, defects and damage, as well as non-destructive testing (NDT) and especially technical diagnostics. From technical diagnostics, the student will get acquainted in some detail with vibrodiagnostics, electrodiagnostics, thermodiagnostics, noise diagnostics, acoustic emission and ultrasound. Other methods of technical diagnostics are also presented and described, such as tribodiagnostics, assembly and optical measurements, multiparametric diagnostics, etc. The student will get acquainted with the approaches in technical diagnostics that are used in today's industry to assess the condition of technical equipment. Today, modern approaches based on remote monitoring, online system administration, evaluation of measured data, visualization, application of artificial intelligence, etc. are also developed and presented in the teaching. The reliability of elements and systems is also discussed in detail and considerable space is devoted to maintenance issues with a focus on modern approaches. The details of the course are elaborated in the way of teaching lectures and laboratory exercises.

Entry knowledge

Prerequisites and co-requisites Basic knowledge of physics, mathematics, statistics and mechanics is expected at the level of completed subjects in the framework of university studies.

Rules for evaluation and completion of the course

The laboratory exercise is completed by a credit (it is awarded in the 13th teaching week). To obtain it, 100% participation in exercises, activity in exercises and elaboration, submission and teacher recognition of protocols (reports) from all prescribed laboratory exercises is required. Further details are communicated to students at the beginning of the semester. Obtaining a credit is a necessary condition for participation in the exam. The exam consists of a written part followed by an oral interview. In the written part, the student will process five assigned questions. In the oral part, the orientation in the studied issues is examined. The evaluation of the written part, the oral part and the overall evaluation of the exam is given by the classification scale according to ECTS.


Controlled participation in lessons: Controlled participation in lessons: 100% attendance at seminars is required. In case of absence, the student is obliged to compensate the lessons.

Aims

Learning outcomes of the course unit The aim of the course is to acquire knowledge in the field of sensorics, measurement and technical diagnostics. These areas of science are important today to understand the problems in technical practice. The aim is also to become familiar with the maintenance of technical equipment, because it can significantly affect the economy of the company. The operability of technical equipment is also associated with an important area, namely reliability. Thus, the aim of the course is to understand the basic facts of reliability.


Learning outcomes of the course unit The aim of the course "Sensors, Measurement and Diagnostics" is to understand the basic facts from the mentioned areas and also to clarify the connections needed for technical practice. Students acquire a relatively high level of competence in the field of sensorics, measurement and technical diagnostics.
