Simulator of current output 0-24mA
Mačišáková, Kateřina ; Benešl, Tomáš (referee) ; Bradáč, Zdeněk (advisor)
This bachelor thesis deals with design of very accurate current output simulator 0-24 mA with microcontroller with resolution 0.001 mA. In the thesis I deal with the market re-search with similar devices, theory and then with the conception of the whole system concept, with the identification of used components and with the evaluation of their suitability. I propose here a circuit diagram and a printed circuit board, which I then produce and install. For the resulting device I design and produce a box that will suita-bly complement and unify the entire system. I will revive the whole device, program it and test its functionality.

Safety analysis and safety measures for Industry 4.0 testbed
Kroulík, Matěj ; Benešl, Tomáš (referee) ; Fiedler, Petr (advisor)
This thesis deals with the requirements of security of machinery with respect to valid security standards. Especially it focusses on standards EN ISO 12100 and EN ISO 13849-1. Further the paper contains overview of security elements of machinery used in industry, also introduce the conception of Industry 4.0 testbed. In the last section, the theoretical findings are used to analyze and evaluate risks and theoretical proposal of security on Industry 4.0 testbed.

Functional model of a small hydro power plant control unit
Rusnák, František ; Arm, Jakub (referee) ; Benešl, Tomáš (advisor)
This semester work deals with realization of functional model of control unit for hydroelectric power station. Main task of this work is realization rectifier with active power factor correction, which is used instead of commonly used frequency converter. Control unit is designed for asynchronous motor in generator operation with self-excitation. The propeller turbine is used as propulsion. Theoretical part includes theory of the PFC converters. Practical part includes calculations for components of PFC converter and assembly of DPS PFC converter.

Application for Industrial Robot Demonstration
Lázničková, Jana ; Benešl, Tomáš (referee) ; Jirgl, Miroslav (advisor)
The aim of this paper is to create a demo application that presents the interaction of the Mitsubishi RV-4FR industrial robot with the SICK Inspector industrial camera. The robot step by step takes out items from the input stock (items can be randomly sorted), uses the camera to identify a specific item. Items that are not in order are placed in the storage stock. Conversely, the items in the corresponding order are folded into two output stocks and creating two different images.

SCARA control system
Bittner, Jakub ; Burian, František (referee) ; Benešl, Tomáš (advisor)
This thesis shows the process of restoring a SCARA type robot, which has had its controller destroyed. The signal cables as well as the power ones were rewired so that it would be able to create new control system for robot arm. New control system is created using devices from Beckhoff company. For that identification of motors is required. After that PC control is programmend to control every single axis of manipulator, with this program vizualizations of controll elements are created. In the end linear interpolation of movement between points is implemented.

Design of mechanical, electrical construction and software equipment of autonomous cell "Ice crusher" for Industry 4.0 testbed.
Horák, Lukáš ; Benešl, Tomáš (referee) ; Pásek, Jan (advisor)
The goal of this bachelor thesis is design and construction of an autonomous cell on a production line with the purpose of being an „ice crusher“. The purpose of this cell is to be part of a Testbed. The cell will be controlled using a HMI touch panel and PLC 1200. Information about how much ice the cell should pour into a glass is stored in an NFC chip on the bottom of the glass. The first part of the thesis comprises of brief introduction to Industry 4.0 alongside with description of the default and current state of Industry 4.0 testbed. Another part describes mechanical and electrical design of the cell. Last part of the cell describes software of the cell alongside with description of testing and installing the cell to the testbed.

A Virtual Model of a Technology Process with PLC Control
Hendl, Adam ; Benešl, Tomáš (referee) ; Jirgl, Miroslav (advisor)
This Diploma thesis describes the procedure of setting the parameters of communication blocks and functions in PLC and PC, so that it is possible to remotely control part of the production process. TCP / IP protocol is used for communication between devices. Part of the production technology is represented by the created 3D model, which serves for three-dimensional interpretation of the simulation of the mathematical model of this part of the process. Part of this work is the design of this model and description of its dynamics.

Pallet conveyor retrofit
Thér, Tomáš ; Jirgl, Miroslav (referee) ; Benešl, Tomáš (advisor)
This bachelor thesis designes new hardware and software designated for retrofit of a pallet conveyor for the purpose of improvement of it's functionability and safety. The work consists of a theoretical describtion of new and already used electrical components, their utilization and creation of the technical documentation. The next part deals with the design of the control software and visualization of the HMI panel. A virtual model of the conveyor was created to test the functionability of the program before it was tested on the real conveyor. The last part consist of funcional safety's theory and its evaluation.

Control system for a cabin
Vávra, Petr ; Benešl, Tomáš (referee) ; Fiedler, Petr (advisor)
This thesis deals with a design of control system for electrical heating and exterior venetian blinds aimed for recreational house with a remote control. The theoretical part contains methods used for house remote control in commercial systems. In the practical part, the system is implemented on PLC and Raspberry Pi. For remote control and communication, the HomeKit protocol has been chosen. Blinds control and electrical heating system are integrated to the HomeKit. For blinds, automatic control algorithm for energy optimization has been chosen and implemented.
