Functional safety of pressure transmitters of BD SENSORS company
Šimoník, Martin ; Hlinka,, Jiří (referee) ; Fuchs,, Pavel (advisor)
This master thesis examines the functional safety of the pressure sensor XMP i which is produced by BD SENSORS Company. The aim of this thesis is the demonstration of compliance of the pressure sensor XMP I with functional safety integrity level SIL3 requirements. The thesis is divided into three parts. The first part deals with the concept of functional safety, defines the basic concepts of functional safety, compares the approaches of functional safety according to selected standards and provides a general procedure for the functional safety determination. The second part deal with technical systems reliability defines reliability indicators and describes selected types of reliability analysis used in practice, especially the FMEA/FMECA analysis. Third part deals with the reliability analysis of the sensor XMP i and with evaluation of results.

Improvement of company processes to assure safety of products
Zvolánková, Kateřina ; Jankových, Róbert (referee) ; Prostredník, Daniel (advisor)
The diploma thesis devotes to the process of ensuring functional safety of products in Bosch Rexroth Brno, which deals with industrial hydraulic systems. The first part introduces the basic legislative regulations concerning product safety and describes selected standards relevant to this thesis. The second part focuses on Bosch Rexroth and the current state in the field of ensuring functional safety of their products. It also includes a description of the functional safety solution of a specific project – a hydraulic try-out press. At the end of the thesis, improvements to the process of ensuring functional safety in response to the identified shortcomings are proposed.

Evaluation of present technologies in ensuring functional safety of machinery
Smetana, Štěpán ; Tůma, Zdeněk (referee) ; Zahálka, Jiří (advisor)
This bachelor’s thesis is concerning functional safety as a whole. The first part of the paper will provide a description of what we can imagine under the term of functional safety and why we should pay attention to it. The document also includes introduction of safety components used in a frame of functional safety and its brief description. You can find here methodical approach to calculation of performance level PL and safety integrity level SIL, this calculation is shown on an example of an emergency stop function.

Automation for welding cell
Lorenc, Michal ; Stibor, Karel (referee) ; Štohl, Radek (advisor)
The work deals with automation, safety and control of the welding cell. At the beginning the possibilities of communication between the PLC and the robot are discussed. Then the work moves on to the definition of the cell requirements and the design of the function concept. This design is followed by a risk assessment which is followed by the design of risk reduction measures, including the design of the specific equipment used. This moves the work to the design and implementation of the control program for the PLC and HMI. The safety features proposed in the welding cell safety section are also addressed in the program. Following the implemented control program, a verification plan is designed and evaluated. And in the last section, suggestions for further development of the welding cell are written and the achieved results are summarized at the end.

Methodology Development and Validation of Software for Safety-Related Parts of Control Systems in Theater Technique
Drlík, Michal ; Suchánek, Rostislav (referee) ; Sinay, Juraj (referee) ; Blecha, Petr (advisor)
This thesis describes what the theatre is and what types of machinery can be found there. Then the issue of stage technical machinery is presented into the czech context, respectively into the Europian legislation with the emphasis on the technical norms usage, which are necessary to fulfil in order to reach this aim. In the next part of the thesis is made the analysis of control systems, which are used in the stage technics with the emphasis on the functionality of these control systems, since this functionality determines number and range of possible danger and dangerous events, later on. These dangerous situations are named and specified in detail, thereby their existence, importance and necessity of solution is being emphasized. There is also a possible solution outlined that these dangerous events can be solved in many cases by using of these programmable systems relating to the safety, thereby safety functions realized by these functions. Then the single steps are described into V-model with appropriate documents of these V-model steps. Outcome of this thesis will be suggested model of method and its development and software validation for programmable and control systems in theatre technology.

Control of special purpose machine tool
Plocek, Jaroslav ; Holub, Michal (referee) ; Houška, Pavel (advisor)
The master thesis treats the design of control system of special purpose machine tool. The first part analyzes and compares two possible variants of control system which use either a CNC control system Sinumerik or motion control system Simotion. Only the variant with the Simotion control system is subsequently examined in detail: its hardware configuration, the selection of components and partly also the software solution. The thesis further deals with the safety of the realized control system and of the whole machine. There are described general safety requirements of machinery based on harmonized European standards and their specific application in the design of safety functions and the safety circuits of solved machine tool.
