Wireless IR Sensor for Area Invasion Detection
Suchý, Lukáš ; Kubíček, Michal (referee) ; Kolouch, Jaromír (advisor)
The target of this Bachelor thesis to design a security system for detection of the monitored space disruption, containing several battery powered sensors which are connected to central unit. From Bachelor thesis is evident, that for communication is to be used integrated circuit SI4432. Sensor detects motion in distance no less than 5 m and sends reports of the space disruption to central unit where this information will be processed. After that the user will be informed by the central unit. Sensor unit should be battery powered with lifetime in years. In conlusion, the system it tested in real work.
Camera Security System with Raspberry Pi Minicomputer
Vitula, Marek ; Kubíček, Michal (referee) ; Kolouch, Jaromír (advisor)
This bachelor thesis describes a design of a camera surveillance system on the Raspbery Pi platform that can be controlled remotely and powered by a solar panel. It includes a description of the individual components to be used and also deals with the design of the application for motion detection using a camera and PIR motion sensor output and the following image processing and storage on cloud.
Small solar power plant
Šimůnek, Patrik ; Kolouch, Jaromír (referee) ; Kubíček, Michal (advisor)
This bachelor thesis deals with the design of a small solar power-station utilizing a lead-acid battery. Its purpose is to provide power for small household applicances. This project consists of a theoretical design of the system, detailed design of MPPT regulator and a design of schematic circuitry and PCB. Finally, actual measured parameters of the whole systém are presented.
Wireless IR Sensor for Area Invasion Detection

The target of this Bachelor thesis is design security system for detection motion of people, focused on battery power sensores, which are connected on central unit.
Photographic battery flash unit
Dašovský, Jakub ; Kubíček, Michal (referee) ; Kolouch, Jaromír (advisor)
The main subject of this bachelor thesis is the design of a flesh unit with a maximum output performance of 400Ws. Regulation is performed by the length of flash. The source of energy used is generated by Li-Ion cells with a total voltage of 21 V and capacity of 5200 mAh. Part of this design include circuits that provide power control to the flash tube, the resizing of the DC voltage (changing), the charging and monitoring of the minimum battery voltage.
Transmitter for professional microphone
Árva, Gábor ; Kubíček, Michal (referee) ; Kolouch, Jaromír (advisor)
This project deals with the design of a transmitter in a wireless microphone system, which connects to a microphone through an XLR connector. It contains detailed description of the individual blocks, which are necessary for processing and transmitting the signal received from the microphone. It discusses methods of frequency modulation using a phase locked loop and compares their advantages and disadvantages. As the last, it deals with the antenna selection and its shrinking methods.
DC/DC converter 12 V to 300 V
Buba, Ondřej ; Kubíček, Michal (referee) ; Kolouch, Jaromír (advisor)
The thesis deals with design of switching power supply to power the oscilloscope. In this project the topology of the DC-DC converter is chosen, the pulse transformer and the output coil is designed. The control circuit is also choosen a suggested. This circuit will be replaced with microcontroler ATMEL in the second part of this thesis. The microcontroler will be programmed to replace the control circuit.
Wireless station with connection to IoT network

Description of component which the station consists is also part of the thesis. Description of created library for control module ESP8266 by microcontroller is also part of thesis. Finally, documents for production of this station are also part of the thesis.
Wireless data acquisition in industry environment
Macura, Jáchym ; Kubíček, Michal (referee) ; Kolouch, Jaromír (advisor)
In the first part of Bachelor thesis is discussed selecting an appropriate standard for wireless data acquisition in industrial environments. In the next part are described the properties of the selected standard ZigBee. The next part is used to introduce and comparison of different ZigBee modules, which are available. In the practical part is represent transmission chain and its description. In the last section of Bachelor thesis are measured results.
SAW resonator controlled FM transmitter
Pokorný, Josef ; Frýza, Tomáš (referee) ; Kolouch, Jaromír (advisor)
This thesis describes design of FM transceiver with SAW resonator. Theoretically analyzes properties of microphone, oscillator and choosing of fitting antenna where it's analyses theirs strong and weak sides. Transceiver has electret microphone. Signal from microphone is amplified by preamplifier OPA134. Further this paper contains oscillator build which output is amplified by monolithic power amplifier and routed through RF filter to antenna.
