Industrial data logger
Matula, Ondřej ; Bradáč, Zdeněk (referee) ; Benešl, Tomáš (advisor)
This thesis deals with the design of an ON-LINE diagnostic system named as "industrial data concentrator". The thesis looks at the design itself in a comprehensive way and brings together parts such as defining useful diagnostic variables, a competitive comparison with already available commercial products and the actual design of the industrial data concentrator both in terms of hardware and software.
FLATcon system – CCD detection of media meters with RF communication
Lancz, Michal ; Jirgl, Miroslav (referee) ; Bradáč, Zdeněk (advisor)
Bachelor’s thesis deals with designing the concept of battery powered miniature microcontroller system based on CCD detection of media meters. The FLATcon design concept contains the necessary inputs and outputs for communication with microcontroller and with peripheral devices. The aim of the thesis is to detect the state of a media meter equipped with an analogue dial, to save the scanned image along with the scanning time and forwarding through the RF module. The bachelor thesis describes FLATcon system design, soldering and supplying the system and testing peripheral devices.
Control system for equipment using renewable energy sources
Novotný, Jan ; Bradáč, Zdeněk (referee) ; Benešl, Tomáš (advisor)
The work deals with design of power and control electronics for water micro source in island network. In the general part the readers are acquaints with the issue of renewable energy sources and describes commercially produced micro sources. The practical part deals with the design of its own control system and power electronics using its own control system or PLC for water micro source. The microcontrollers were used for the implementation of the control system, for which the program part was created.
Separation control of chemical solutions by high voltage supply pair
Zálešák, Jiří ; Bradáč, Zdeněk (referee) ; Štohl, Radek (advisor)
This thesis deal with detailed conception separation control of chemical solutions by high voltage supply pair. In the first part of solving is projected galvanic separation high - voltage supply from control system. Second part deal with on programming control algorithm in PLC AMiRiS99. Third part deal with communication PC – PLC and conception finished aplication.
Detecting RTOS Runtime Anomalies
Arm, Jakub ; Jalovecký, Rudolf (referee) ; Blecha, Petr (referee) ; Bradáč, Zdeněk (advisor)
Due to higher requirements of computational power and safety, or functional safety ofequipments intended for the use in the industrial domain, embedded systems containing areal-time operating system are still the active area of research. This thesis addresses thehardware-assisted control module that is based on the runtime model-based verificationof a target application. This subsystem is intended to increase the diagnostic coverage,particularly, the detection of the execution errors. After the specification of the architecture,the formal model is defined and implemented into hardware using FPGA technology.This thesis also discuss some other aspects and embodies new approaches in the area ofembedded flow control, e.g. the integration of the design patterns. Using the simulation,the created module was tested using the created scenarios, which follow the real programexecution record. The results suggest that the error detection time is lower than usingstandard techniques, such a watchdog.
River wireless monitor
Michník, Jakub ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
This work presents hardware and software design for River wireless monitor Rabbit Core module RCM5400W. It describes possible solutions for measurement of river characteristics, in particular water level height. Pressure method measuring and selection of important electric parts are described in more detail. The software for Rabbit Core module RCM5400W and also web sites are described here.
Datalogger with Ethernet
Orávik, Tomáš ; Šťastný, Ladislav (referee) ; Bradáč, Zdeněk (advisor)
Thesis deals with Datalogger with Ethernet interface controlled by DISCOVERY Kit STM32F429. Datalogger is equipped with eight digital inputs and three analogue inputs. The measured data are saved on the SD card. The Ethernet interface module is designed using LAN8720A from Microchip.
Datalogger of environmental values
Raichl, Petr ; Benešl, Tomáš (referee) ; Bradáč, Zdeněk (advisor)
The thesis is aimed on construction of solar panel powered datalogger of environmental values. The thesis begins by research of commercial dataloggers. Then the concept of datalogger was created. Then the electronics of datalogger was designed. Datalogger is built as a system driven by microcontroller. The microcontroller reads data from sensors, writes data to memory card and sends data to Czech radiocommunications cloud by LoRa technology. Then the data are resend to MySQL database. Program for microcontroller was made in C language. Configuration of datalogger is done through USB interface by PC application which was created in C# language. For visualisation of measured data ASP.NET Core application was created.
Compact datalogger with flash memory
Vágner, Martin ; Hynčica, Ondřej (referee) ; Bradáč, Zdeněk (advisor)
This thesis deals with design of small datalogger with flash memory card. At first are discussed parameters, functions and features of dataloggers. The second part deals with a problem of digital measurement of analog signals. The rest of this thesis gives attention to main goal which is design of datalogger. It consists of circuit diagram, layout of printed circuit board, firmware for microcomputer and software for PC.
Flat monitoring system
Ďurík, Maroš ; Fiedler, Petr (referee) ; Bradáč, Zdeněk (advisor)
Thesis deals with flat monitoring system that measures basic parameters like temperature and humidity, power energy consumption in kWh, leakage of natural gas, lighting and power failure. This Device communicate with user trough the Ethernet protocol and include simple WWW server where measuring data are shown.
