Home security system
Čada, Jan ; Burda, Karel (referee) ; Lattenberg, Ivo (advisor)
This master thesis deals with the design and implementation of a security system for a family house. It consists of a central control panel, a control keyboard and detectors connected using cables. The first part of the thesis discusses the electronic security and fire alarm systems, describing the individual elements of these systems and their different types. Magnetic contacts, fire detectors, sirens and a mains power supply with UPS function are selected from the current offer based on a comparison of parameters. In the next section, a block diagram of the whole system is designed. Raspberry Pi Pico development board with an RP2040 microcontroller is selected along with a GSM module SIM800L for SMS alarm notification and an Ethernet module with a Wiznet W5500 chip for the possibility of implementing a web interface. Schematics of the individual modules of the system are designed - for the central control panel, input module with PCF8574 circuit and two PCBs of the control keyboard module, which is equipped with a button keyboard with backlight, character LCD display type 1602 and proximity sensor VL53L0X for automatic lighting when person comes closer than a defined distance. PCBs are designed according to the schematics. Their manufacturing is then ordered, all components are mounted and the PCBs are placed in a 3D printed enclosure in the case of the control keyboard, and on the mounting plate of the metal cabinet in the case of the central control panel, according to the designed mounting plan. For the selected piezo sirens, covers are designed and 3D printed in the design of the selected Paradox NV5 motion sensors. In addition to the central control panel and the control keyboard, door and window contacts, fire detectors and sirens are installed in the house. The next part is dealing with the development of the control software for the central control panel and control keyboard in MicroPython language and the design of a custom communication protocol on the RS-485 bus for communication between the central control panel and control keyboard. Both control programs are based on the state machine principle, and their state diagrams are presented in the thesis. Part of the text is also focused on the development of the central control panel web interface and integration of the desinged system into the Home Assistant open-source automation system. The last part describes the activation and testing of the system in real conditions of a family house.

Electronical alarm system for family house
Fránik, Marek ; Richter, Miloslav (referee) ; Macho, Tomáš (advisor)
The aim of this work is to propose an electronic security system for the house, tha will be respond to the security violation by using siren and GSM module. The objectives of this work include programming software for central unit and debugging that software. The proposed central unit would be compatible with commonly solded sensors and sirens.

Low power GPS locator
Hus, Peter ; Háze, Jiří (referee) ; Pavlík, Michal (advisor)
The aim of the work is to design a low power GPS locator which will serve as a security device for location tracking and checking vehicles status. The designed device will be able to identify unauthorised manipulation of the vehicle and warn a user through SMS message. The device will be sending some information from GPS module in case of a theft regularly. The design is focused on the lowest current consumption, wide range of operating temperatures and reliability.

Intelligent monitoring device
Nosek, Zdeněk ; Šteffan, Pavel (referee) ; Kadlec, Jaroslav (advisor)
This master thesis discusses design and realization of a security device for vehicles. This device can determine its actual location, discover unauthorized trespass and send information about this to a distant master system too. This distant master system can show the exact position of the security device on a map. The hardware and software for this security device and the software for the master system are described in this paper.

GSM alarm for motorcycles
Beníček, Martin ; Fedra, Zbyněk (referee) ; Urban, Josef (advisor)
The main target of this work is to design and to implement unfailable safety appliance for motocycles with use any GSM technology. In my masters’s thesis I applied to individaul fields which I had to knows for realization of this work. The introductory chapter tells the reader about evaluation of former semestral projects and about brief description of the realized mechanism. It is followed by descripctoin of principles of communication between PC and mobile phone. The main part of my work is dedicated to application itself. The applicaton is called motoalarm. The last chapter creates description service of localisation mobil phones which is called Kde je... The conclusion includes evaluation of this master´s project and general description of the realized mechanism.

Planar LED Display Application
Houserek, Jiří ; Kosina, Petr (referee) ; Šandera, Josef (advisor)
This coursework deals theoretical with design and construction of the electronic clocks controlled by DCF77 signal, which is broadcasted from Germany. This device will be used as alarm and is able to show date. There is used display, which consists of 8x32 LED matrix in a modular, which is connected to main board over the edge. This device is controlled by microcontoller PIC16F887A. There are described displays, microcontrollers and DCF time signal.

Automatic detector of vehicle road accicents
Žurek, Jan ; Morský, Ondřej (referee) ; Dostál, Otto (advisor)
This master‘s thesis treat of car safety. It includes an introduction into already existing active and passive safety systems and briefly describes their basic principles. It also includes a description of basic principles of car electronic systems. It will acquaint us also with elementary calculations in the area of car crashing into a solid obstacle. On base of this information was developed and consequently realized development module of an automatic car accident alarm that transfers information using SMS messages to a cell phone. The message contains date, time and GPS coordinates of the accident and acceleration sensor readings in three axes.
