Input module of electronic speedmeter RE 1xx
Feilhauer, Petr ; Sirka, Martin (referee) ; Zezulka, František (advisor)
This master’s thesis contains a basic description of the function and wiring of Electronic tachograph RE1xx from company UniControls - Tramex. The main objectives of this thesis are design and implementation of a functional module, combining the four frequency inputs, two analog inputs and eight digital inputs. The proposed module must be fully compatible with current system of Electronic tachograph and must be according by the basic technical-law standards, which refer of this branch for application this device. Based on the analysis of methods of processing various signals are proposed several concepts of the input module. Individual concepts are described with advantages and disadvantages. On the design concept of this module, followed by a description of the speed sensor, is placed on the redress of vehicle. Design of circumferential involvement of the chosen conception is detailed described and divided into several parts (controlling part, frequency inputs, analog inputs, binary inputs). In this module is accent on increased reliability and interoperability, which is achieved by using for example: power monitor, external watchdog, etc. For realization prototype is a part of thesis design of the PCB. Thesis includes theoretical calculations, which is needed for the design of software. On a functional input module is developed and debugged operating firmware, which is based on single-fiber design of the program. To measure the actual speed are debugged two algorithms - method of periodic sampling and the method of external interrupt. The following is a description of the measurement and processing of analog and digital signals (used algorithms suppress oscilation of input signals). The result of this master’s thesis is functional Module of frequency, analog and digital inputs, which measures vehicle speed, distance covered, direction of movement, two analog signals and evaluates states of the binary signal. Preprocessed data are sent to a Module of central processor through serial communications RS485.

Control algorithms for e-car
Hrazdira, Adam ; Fiedler, Petr (referee) ; Zezulka, František (advisor)
Cílem práce byl návrh a implementace řídicích algoritmů pro optimalizaci spotřeby energie elektrického vozidla. Hlavním úkolem byla optimalizace rozložení energie mezi hlavním zdrojem energie (bateriemi) a super-kapacitory v průběhu jízdního cyklu. Jízdní výkonový profil je odhadován a předpovězen na základě 3D geografických souřadnic a matematického modelu vozidla. V první části jsou uvedeny komponenty vozidla a jejich modely. Poté jsou představeny algoritmy na základě klouzavého průměru a dynamického programování. Byly provedeny simulace a analýzy pro demostraci přínosů algoritmů. V poslední části je popsána Java implementace algoritmů a také aplikace pro operační systém Android.

Data analysis from the manufacturing process
Krčmář, Martin ; Honzík, Petr (referee) ; Zezulka, František (advisor)
This thesis deals with the classification of production data using algorithms: neural networks, decision trees and naive bayesian classifier. The neural network is dedicated forward multilayer networks with a learning algorithm of backpropagation. In thesis, these algorithms are described and evaluated their pros and cons. Another part deals with the development of the program in C# for creating these algorithms. The last part is devoted to the evaluation of the results. Bachelor thesis contains a sample of generated clasification models decision tree and bayesian classifier.

Optimal Control Strategies for Building Energy Consumption
Kaczmarczyk, Václav ; Horák, Bohumil (referee) ; Janeček, Eduard (referee) ; Zezulka, František (advisor)
This thesis discusses the operational coordination of electrical appliances and devices in a smart home. At present, the diminishing volume of fossil fuels and the increasing pressure to use renewable sources of energy necessitate the integration of such volatile sources into electrical grids. This process, however, results in higher energy costs, and the consumers are thus more willing to change their behaviour to either reduce the expenses or maintain them at a reasonable level. One of the relatively few customer-oriented options to optimise energy costs consists in the demand – response principle, which utilises external information to minimise energy consumption during high price periods. Assuming the constantly changing conditions in electrical grids, and thus also the varying demands, it is vital to provide for automatic optimisation excluding the need of user intervention. The thesis presents a method which, after being implemented into the control member, will facilitate the optimal use of appliances and devices within a smart home. As the behaviour considered optimal from the perspective of demand - response is often inconsistent with the consumer‘s requirements for comfortable use of the appliances, the proposed technique offers a compromise through enabling the consumer to select the appropriate strategy. Five universal optimisation models are designed within the thesis; these models facilitate description of common home appliances and local electricity sources. The core of the method lies in formulating and optimising a mixed integer quadratic problem (MIQP). The optimisation task yields an operational schedule for the individual appliances, and this scheme considers the energy costs, the working cycle of the appliance, the user’s demands, the system restrictions and/or other input data. Furthermore, the author extends the above-discussed general technique, enabling it to adopt robust behaviour. The method then secures the preset strategy even during a marked change of the input conditions, and its robustness is a viable precondition for the overall applicability of the technique in the real control member.
