CIP industrial protocol simulation
Molent, Michal ; Musil, Petr (referee) ; Blažek, Petr (advisor)
The thesis is about industrial automatic CIP protocol, which belongs to SCADA systems. The first part is focused on basic principles of CIP protocol and on analysis of two protocols (EtherNET/IP and DeviceNet), which are based on CIP protocol. The second part deals with designing scenarios for a simulation. The simulation of one-way communication, two-way communication with help of reads from the console and two-way real time communication between Raspberries PI 3B+. The third part deals with a realization of the simulation, a start-up and a function of predefined scenarios and graphic interface. The fourth part deals with analysis network communication in situations, which occur during a protocol EtherNet/IP simulation.

Management of the energy transmission system polygon
Bohačík, Antonín ; Musil, Petr (referee) ; Blažek, Petr (advisor)
The diploma thesis is focused on the creation of a control interface for a polygon simulating the electrical distribution network of the Czech Republic, where communication between substations is realized by IEC 60870-5-104 protocol. The theoretical part of the thesis explains the basic principles, properties and possibilities of communication standards IEC 60870 and IEC 61850. The next part is focused on the actual implementation and subsequent implementation of the control interface, including the implementation of the IEC 61850-80-1 module for data transfer between the mentioned standards. The last part describes the created behavior scenarios or the analysis of communication itself.

Model Train Controlled by Microcomputer
Látal, Tomáš ; Musil, Petr (referee) ; Zemčík, Pavel (advisor)
The goal of this bachelor's thesis is to verify whether and how it is possible to control a model railroad using Raspberry Pi. Another goal is to create a minimalistic model railroad control system using non-specialized equipment available to ordinary user, taking into account the possibility of controling this system using smartphones or tablets. The final result is the system implemented in C++ and Python~3 languages using Arduino Motor Shield R3 with H-bridge L298P.

Hardware acceleration of object detection in images
Musil, Petr ; Chalmers, Alan (referee) ; Kadlec, Jiří (referee) ; Zemčík, Pavel (advisor)
V dnešní době je patrný nárůst počtu kamer a dohledových systémů ve veřejném prostoru. Množství informací které tato zařízení produkují je enormní a není v lidských silách je všechny vyhodnotit a interpretovat. Použití výpočetních technologií je nezbytné. Moderní algoritmy počítačového vidění již dosahují skvělých výsledků, jejich širšímu použití v praxi zatím brání nízký výkon zařízení a vysoké požadavky na výpočetní zdroje a energii. Jednou z možností je využití vysokého paraelního výkonu FPGA pro efektivní zpracování těchto algoritmů. Cílem této disertační práce je představit navržené metody optimalizace detektoru objektů v obraze běžících na FPGA. Tyto detektory využívají boostovatelné soft kaskády klasifikátorů spolu s lokálními obrazovými příznaky, které slouží jako slabé klasifikátory. Navržené postupy využívají sekvenční vyhodnocení slabých klasifikátoru. Pro zvýšení výkonu detekce je vyhodnocováno současně více pozic v obraze. Je navržen nový přístup pro detekci objektů různé velikosti nevyžadující externí paměť. Vytvořené detektory byly experimentálně ověřeny na úlohách detekce obličejů a poznávacích značek automobilů. Dosažená výsledky překonávají současný stav poznání, umožňují vytvořit detektory objektů s vyšším detekčním výkonem, lepším poměrem výkonu a spotřebovaných zdrojů FPGA a s lepší přesností detekce.
