Microbending fiber optic sensors
Švestka, Jiří ; Štohl, Radek (referee) ; Šedivá, Soňa (advisor)
This thesis deals with the influence microbending the transmitted signal at the bare optical fiber. Microbending influence on the transmitted signal is investigated in this work by changing the weight, power and water level in the tank by using this test fixture. The results of the experiments are proposed to enter the laboratory tasks to measure the impact microbending the transmitted signal in the subject line fiber-optic sensors (MOES).

Communication by PLC with peripherals of model elevator
Goryl, Stanislav ; Hynčica, Ondřej (referee) ; Štohl, Radek (advisor)
The theme of this bachelor thesis was to create firmware for internal and external control panel for a model of a lift. Control panels communicate with the upper-level control system via the AS-Interface fieldbus. The base of the firmware is the finite state machine. In the introduction of the thesis, there is a brief description of the AS-Interface bus and the outline of the principle of data transfer. Followed out, is the description of firmware for control panels. Furthermore, there was created a test application for PLC which verifies the functionality of control panels. In the last part, there was produced a manual for the firmware programming, including the construction of untypically involved programming cable.

Electronical system for greenhouse control
Šedivý, Jozef ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
The aim of this bachelor thesis is to develop an electronical system for greenhouse control, controlled by microcontroller. This device has been divided into 2 parts, which communicate between each other via RS422 interface. The system contains temperature, humidity and illumination sensor. Based on data from sensors, it controls climate conditions in a greenhouse.

Wireless communication between remote PLC and lab model
Maléř, Martin ; Šír, Michal (referee) ; Štohl, Radek (advisor)
The main aim of this bachelor’s thesis was to establish wireless communication between programmable logic controller (PLC) used in laboratory model of a distillation column and PLC, which controls the technological process. Industry bus ModBus TCP/IP and wireless modules in client-server mod was chosen to reach this goal. To control the technological process was created visualization. At the finish of the work everything was tested.

Control of the pneumatic press
Lichosyt, Tomáš ; Pásek, Jan (referee) ; Štohl, Radek (advisor)
This thesis deals with the creation of the control program according to the standard 88. Document contains a brief description of the security features of the model of the pneumatic press. It also focuses on the description of the standard 88 and its subsequent implementation on the pneumatic model. Next part of this document describes the development environment FactoryTalk Batch, which will be used for batch control. The next is a description of the phases formed in RSLogix 5000, configures and recipe created in the FactoryTalk Batch software. The last point is the creation a product for pressing and stamping.

Control of Curalon cycle batcher
Jílek, Tomáš ; Hynčica, Ondřej (referee) ; Štohl, Radek (advisor)
The work deals with the controlling design of batching machine polyvinyl alcohol fibre, its integration into existing production technologies and the real implementation and verification of the machine functionality for which a design has been made. It also includes a design and implementation operator panel through which can be possible for production line supervising staff to set parameters and monitor the process. Firstly, there is described the default process of dosage, required conditions and restrictions for the newly established dosing machine. In the following part features of newly designed batcher are described, further it deals with the basic parameters and characteristics of selected components, which are important for the execution of its own proceedings. The next part of the work is concerned in detail with the implemented function of controlling algorithm and operator panel, which is provided through interaction with the staff supervising the production line. The last chapter provides the basic configured parameters of the controlled components.

HW and SW for Ethernet-to-IEEE802.15.4 bridge
Růžička, Tomáš ; Štohl, Radek (referee) ; Fiedler, Petr (advisor)
The present work includes theoretical information about network protocols, Ethernet (TCP/IP) and IEEE 802.15.4.Work also includes design of the converter realiyed using the development kit RCM 3365 from the Rabbit Semiconductor company. The converter works with the UDP, which can be converted to packets of wireless standard, or from a wireless packet can create a UDP packet. The wireless part was replaced with a serial interface RS-232, after which the packets travel in wireless standard IEEE 802.15.4. To create and monitor data on the Ethernet and RS-232 three external programs are used.
