Laboratory execises using ADAM industrial sensor system
Bocek, Jan ; Mišurec, Jiří (referee) ; Rampl, Ivan (advisor)
Main task of the Bachelor Thesis is to familiarize with industry sensor systems that are realized on measuring panel. It is necessary to understand its communication and suggest 2 laboratory exercises. Realized industrial sensor system is assembled of 6 ADAM 4000 modules, which are made by Advantech company. It is decentralized measuring system, comunicating by interface RS-485 and with PC by bus RS-232. The first designed exercise is „Determination of position and mass weight“ and second exercise is measurement on „Thermal quantity sensor“. It was measured in developing environment ADAMview which is designated for modules ADAM. The reason for usage of sensor system is to reduce the time of measurement, make it more confortable, more accurate, simplify elaborating results and makes it possible for considerable automatization of measurement.

Virtualization of ARM architecture and development of a universal control platform for embedded systems
Páleník, Luděk ; Mašek, Pavel (referee) ; Zeman, Kryštof (advisor)
Bachelor thesis "Virtualization of ARM architecture and development of a universal control platform for embedded systems" deals with theoretical analysis of IoT devices, M2M communications and virtualization techniques -- especially emulation of different processor architectures. The practical part is implementation of the modified emulated image for CM-T43 module from Texas Instruments manufacturer. QEMU emulation tool installed on Linux operating system is used for emulation. Another part of this work is to develop an application that allows reading and writing of data from / to each sensor based on a serial line (RS-232, RS-485) and Ethernet. The application is written in language C and uses the MODBUS protocol.

Design of humanoid racing robot
Zajíc, Jiří ; Marada, Tomáš (referee) ; Věchet, Stanislav (advisor)
Thesis deals with the selection and preparation of robot for competition RoboCup HumaoidLeague. As a basis for robot is used Robotis Bioloid Kit. The kit is extended with a new control unit Roboard-100, rotation and acceleration sensor, a webcam, and Li-Pol batteries. Furthermore, it examined communications between servo drives and designed signal converter from the USB to Dynamixel bus. Its functionality is then tested on the basic control programs.

Sensor emulation tool
Gromeš, Jan ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
The goal of this thesis is design of platform capable of sensor output emulation. The platform allows to emulate either digital sensors, communicating over UART, SPI, I2C, CAN and RS-485 buses, or analog sensors and sensors with frequency output. Design of computer interface to configure the platform is also a part of the thesis. Special emphasis is placed on the universality and overall user-friendliness of the entire system.

Simple Remote Signalling of PLC Systems
Kacálek, Jan ; Šimek, Václav (referee) ; Tříska, Vít (advisor)
The aim of this thesis is the design and manufacture of hardware and software facilities used for the demonstration of communication with PLC systems. Furthermore, this paper summarizes the possibilities of communication and partially implements the MODBUS protocol via RS485 serial line. The hardware device is fabricated on the PCB and the components commonly available in electronics stores. Includes LCD display and LEDs for status display PLC system. The software application is written in Java and implements the same functionality as the hardware device.

Meassuring system for building constructions
Flagar, Vojtěch ; Fiedler, Petr (referee) ; Bradáč, Zdeněk (advisor)
This paper deals with the hardware and software design of the data acquisition distributed system with large amount of connected sensors. The intended application of this work is measuring some physical quantities in the building constructions. The designed system is hierarchically divided into the three levels. On the highest level there is a single-board computer Raspberry Pi which is used as a master on RS-485 bus. There can be up to 32 slave devices on the bus while each of them collects data from the sensors connected to 4-channel I2C bus. At the same time the Raspberry Pi is used as a web server, providing the user interface of the system.

Wireless M-Bus communication system
Baštán, Ondřej ; Šťastný, Ladislav (referee) ; Fiedler, Petr (advisor)
The thesis deals with the design of wireless communication system using Wireless M- Bus, which works in the 169 MHz band. This system is designed to collect data from meters that are not equipped with a radio and have pulse outputs. The thesis describes the Wireless M-Bus standard and the current components of the communication system used by ModemTec. It also describes the selection and design of a suitable hardware implementing the receiver and transmitter modules and the firmware design for these modules. The thesis deals with the parameterization of the transmitter module in order to specify the parameters of the transmitted measured quantity.

Program for Monitoring RS485 Bus Communication
Zukal, Marek ; Smrčka, Aleš (referee) ; Peringer, Petr (advisor)
The goal of this project was to solve recording and displaying the data from the control bus of the traffic light controller device. A program for recording the data was created for the usage on an embedded PC. A portable application with a graphic user interface was implemented to display singal image from the recorded data.

Versatile Control Unit of Solar Collectors
Tříska, Vít ; Růžička, Richard (referee) ; Šimek, Václav (advisor)
This thesis deals with design and implementation of a versatile control unit, which is primarily designed for control of solar collectors. It describes the various stages of design. First, the system of solar collectors is introduced. Its input-output parts are analyzed and the requirements are determined for the control unit. The characteristics of temperature sensors are examined, the work deals with continuous variable speed circulators. The following part is dedicated to hardware and software implementation of the objectives of the work. The boards were designed in Eagle design environment, the firmware was written in C programming language. In conclusion, the evaluation of the results of the proposed system and possible ways of its further development are discussed. The versatile control unit can be deployed in practice realistically.

Service unit for BUSE devices with remote management
Musil, Roman ; Sýkora, Tomáš (referee) ; Bradáč, Zdeněk (advisor)
The aim of this thesis is to create compact device which allows remote management of low-level devices of public transport information system. The thesis first deals introduction to the issues of the information system as a whole and its requisites. After that the thesis analysis the hardware of the existing board computer which the design was based. The next points od this thesis are focused to design and create software for upgrade firmware of information panels created by BUSE company and also for design and create system for remote managment. The conclusion summarizes obtained information and the results achieved.
