Model of small air press
Uherek, Vítězslav ; Macho, Tomáš (referee) ; Štohl, Radek (advisor)
This thesis deals with design construction of laboratory model of air press and also proposes of safety measures for this machine. Before the design itself, norms concerning machinery construction were surveyed. There are two norms mentioned in the text ČSN EN 61 508 and ČSN EN ISO 13489-1. Next part shows practical demonstration of machine safety analysis using SISTEMA software tool. Changes to the safety measures were made according to the result of this analysis. Important part of this thesis is also design of control software for the air press in RSlogix5000 environment using Ladder logic and also created visualization of pressing process and show up on to visualization panel PanelView 700.

Safety of small press model
Peňáz, Ondřej ; Hynčica, Ondřej (referee) ; Štohl, Radek (advisor)
The work deals with the safety of an air press model. After examining the standards to carry out risk assessment, changes are implemented to compliance with safety requirements. Safety inspection is made according to standard ČSN EN ISO 13489-1. A software SISTEMA was used for the control of safety requirements. Description of a software equipment by Rockwell Automation and design of the control program in RSLogix 5000 in ladder diagram is the part of the work. The control is also proposed by the visualization application FactoryTalk for the touch panel PanelView Plus 600.

Extrication of Persons Trapped in Crashed Vehicles with Respect to their Construction
Pirner, Adam ; Kupka, Petr (referee) ; Vémola, Aleš (advisor)
This thesis deals with the topic of extrication of people trapped incrashed vehicles regarding the construction of the vehicle. Part of the resources needed for this theses was taken from a literary survey drawn up with the help of the Research and scientific library in Hradec Králové according to the given topic and key phrases. The first part of the thesis deals with specific parts of the constructions of cars. This part is followed by description of road accidents, various kinds of accidents and possible deformations of cars after accidents. The thesis deals with extrication itself made by fire brigades, suitable procedures, kinds of interventions and means of used technical equipment. Another part suggests ways of saving trails and evidence during road accident interventions. Final part of the thesis is focused on overall analysis of the given problem based on personal experience, suggestions, negative aspects of the current situation and differences in training of possible situations with reality at the site of the accident.

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.

Peristaltic Pump Controll Unit
Charvát, Jakub ; Kopečný, Lukáš (referee) ; Ligocki, Adam (advisor)
The work deals with the problematic of peristaltic pumps and it collects theoretical background information of this topic. The primary goal of the work is the implementation of peristaltic pump and the implementation of protection against equipment damage by overpressure. The overpressure evaluation system in this thesiss on the principle of current measurement of the motor pump. In this work, this premise is successfully tested and applied to the device. Another goal of this work is to create a desktop application that will monitor and control the pump. he data between the application and the device were successfully transfered by the MQTT communication protocol. The communication between the computer and the pump has been tested successfully.

Presure measurement in infusion system
Fialová, Lenka ; Mézl, Martin (referee) ; Harabiš, Vratislav (advisor)
The first part of this work is about history of infusion technology, specially about recent developments in electronic infusion devices. Then, there are described basic principles of infusion pumps and syringe pumps. The second part introduces safety features of infusion technology. An occlusion alarm is one of them. There is described a method of measurement that verifies the functionality of this alarm in two instruments of different producers with various settings. Data obtained by this method are statistically processed and the results discussed.

Safety of pneumatic press model
Nešpor, Tomáš ; Foukal, Roman (referee) ; Štohl, Radek (advisor)
This thesis is concerning functional safety of machinery, concretely safeguard of model of pneumatic press. In the document is briefly introduced norm, which determines safety standards during designing of safe machine. In the next part is mentioned risk assessment written as technical report. In risk assessment are identified possible risks that could appear during working on machine. Furthermore there are listed safety precautions ensuing from assessed risks, list of elements which has been used to safety control of pneumatic press and evaluation of risks according to EN ISO 13849-1 norm. In the part Programming of the device (Programování zařízení) is configuration manual of the device and description of control programme. The description of visualization in FactoryTalk programme is at the end of this thesis.
