Komunikační zařízení přes GSM/GPRS / Communication devices over GSM/GPRS

Prečan, David January 2010 (has links)
This master thesis deals with a data remote transmission by means of SMS and GPRS technology. The overview of current solutions is presented and then a remote temperature measurement and a data transmission employing a communication module GSM/GPRS TM1 through GSM network using GPRS technology is described. As a response to an impulse, the communication module sends SMS. The technical solution is described in details including HW and SW design of the data transfer and processing equipment using a ATmega 162 microprocessor. This equipment communicates with a server (PC), which displays the measured temperature. A prototype which was used for a validation of the design is also described.

Systém ovladatelného dekorativního podsvícení / Controllable decorative lighting system

Pelán, Pavel January 2011 (has links)
ecorative lighting strips could be used to the backlight of furniture, to creating a modern interior design. From an architectural point of view, this design is very difficult and requires a strong sense of aesthetics. More easier is to use the LED strips to the advertising trailers or to backlighting car parts. RGB strip will be powered by switching power supply with galvanic isolation. Colour will be changed by the combination of basic colours RGB, by using 3-channel PWM of Atmel microcontroller, controlled via a wireless module, providing two-way communication..

Bezpečnostní a monitorovací systém rodinného domu / Home Security and Monitoring System

Valach, Lukáš January 2016 (has links)
The thesis elaborates on an implementation of wireless home security system. The wireless communication utilizes IEEE 802.15.4 radios and ZigBee communication protocol. The beginning of the thesis provides specification of the intended system followed by an evaluation of usable energy harvesting solutions and later by consideration of single board computer systems suitable for implementation of the control node of the sensor network. The rest of the thesis describes design, implementation and testing of particular components of the security system. Conclusion evaluates the achieved goals and offers suggestions for future work. The end products of the thesis are physical devices implementing wireless sensor nodes, control unit of the security system as well as a graphical user interface for the system management.

Analýza pohonu modelu domovního výtahu s EC motorem / Drive model for EC motor elevator analysis

Javořík, Zdeněk January 2010 (has links)
The master thesis encompasses the possibilities of position evaluation and drive control with the aid of SMI work enviroment. Furthermore the thesis is directed to create a program through a designed control algorithm. The work is realised on the elevator model with electronically commuted motor. An incremental scanner is used as the position sensor. The motor control unit is set up and programmed in the SmartMotorInterface software. In the next part, measurements with altered parameters are conducted. On the basis of these measurements the influence of parameters on the positioning process and its accuracy is evaluated. At the conclusion of the work, a design of laboratory task for educational purposes is created. The laboratory task is composed in such a way, that students would become familiar with the SMI work enviroment and would be able to practicaly test the setup of incremental position sensor and motor control with the aid of entered algorithm.

Multifunkční volant Formule Student / Multiple-funktion steering wheel Formule Student

Paulus, Luboš January 2011 (has links)
The Master‘s thesis deals with a creating of display writers on multiple-function steering wheel Formule Student. It is mainly about dates transfered through RS232 or CAN bus from control unit of the Formule to microcontroller. First of all it is necessary to find out, which informations and a which way of displaying them are more useful and readable for drivers. This leads to another point - right choice of display writers, which will be used on the steering wheel. Creation of the design and construction of display device follows.

Racionalizace konceptu připojení fotovoltaické elektrárny / Rationalization of the concept of photovoltaic power station connection

Svozil, Marek January 2015 (has links)
This masters thesis addresses the racionalization of the concept of photovoltaic power station connection. A way of compensation valuable components involvement standar- tizovaným inverter controlled by a microcontroller. Also includes the measurement of voltage and current using a microcontroller. The output voltage of the DC/DC con- verter is controlled by the variable duty cycle of the PWM signal generated by the microcontroller ATmega32.

Univerzální hardwarová platforma podporující operační systém Linux / Universal hardware platform supported Linux operation system

Skopal, Miroslav January 2010 (has links)
This thesis deals with the development problems and creating of the multi- purpose hardware platform, which supports operating system Linux. It is focused on the microprocessors using ARM architecture with architecture ARM7, ARM9 and ARM11. The scope of the first part of this thesis was searching the sales of available 32 bit ARM microprocessors. The second part is attended to a particular Mini2440 development kit, its animation and the subsequent development of the kernel drivers for OS Linux platform. One of this thesis details was also the development of my own expansive hardware module and a capacity keypad for a usage with Mini2440 developmental kit.
