Automatic control system for a hot water and hot fireplaces inserts
Hofman, Miroslav ; Marcoň, Petr (referee) ; Friedl, Martin (advisor)
The work deals with the design automatic control systems for hot water and hot fireplace inserts. Control panel with LCD display and buttons to adjust the temperature in the room is connected to temperature sensors, pumps and fans. Data are processed by a microprocessor Atmel. Microprocessor program is written in C, in the environment AVR Studio 4. Microprocessor with peripherals defines the room temperature.

Control modul of the biaxial cartesian manupulator for PLC S7-1200
Hofman, Miroslav ; Kledrowetz, Vilém (referee) ; Pavlík, Michal (advisor)
This thesis deals with the design of module for control of biaxial cartesian manipulator. Control module recieves signals STEP and DIR from PLC - these signals can have frequency up to 100 kHz. They are processed by the module and send to inputs of drivers, which control motors of biaxial manipulator. Both axis of manipulator are driven simultaneously. PLC is not able to manage this process without this module. Adjusted parameters are displayed on LCD display. Control module is disturbance-resistant. All signals are isolated by fast optocouplers, which guarantee minimum distortion of signals. Data are processed by microprocessor ATXMEGA. Program of microprocessor is written in the C language. It is possible to switch module to NPN or PNP logic and it is also possible to select output voltage 5 or 24 V according to the type and adjustment of used driver for motor control.
