Sensor fusion for detecting and locating people in a room
Vondráček, Jakub ; Dobossy, Barnabás (referee) ; Najman, Jan (advisor)
This diploma thesis deals with the problem of fusion of several sensors for the purpose of detecting and locating people in a room. It is primarily about using measured sensors and implementing them in such a way that their connection creates a system that has obvious advantages compared to more expensive single sensor solutions. In the first part of the work, research is carried out, which presents the basic issues of detection, localization and counting of people in rooms. To be used in the practical part of the work, it is also indicated here which specific sensors can be used to achieve these functions and which control units are suitable for such a system. Finally, it summarizes specific components and software tools, which are further supplemented in the practical part of the work. The rationale for this selection is also included. The second part of the thesis describes the specific design of the resulting system, which can perform the functions of detection, localization and counting of people in the room. This practical proposal is described including all starting points, connections and especially the algorithm that was used for sensor fusion. The entire system is subsequently tested, based on which its functioning is evaluated. In the last section of the thesis, the created system is supplemented with a model of a cover and wall mount.

Autonomous Monitoring of Person Movement for Proposal and Evaluation of Energy-Saving Procedure Variants
Malinowski, Radim ; Tříska, Vít (referee) ; Strnadel, Josef (advisor)
The aim of this bachelor thesis is to design device that will be able to monitor and record movement of persons in certain area of a building for later evaluation of its energy efficiency. Partial goals related to this work are: to analyse energy efficiency of public buildings, to design a printed circuit board, to implement a C-language program to control a microcontroller, to put the device prototype into a real operation and finally, to evaluate the data collected by the device. The data is written on a microSD card in XML format using a Freescale MC9S08JM60CLD microcontroller. The resulting device is able to monitor a space for at least two weeks.
