System for Autonomous Data Collection from Weighting Sensors
Lučanský, Adam ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
Práca sa zaoberá automómnym zaznamenávaním váhy včelích úlov. Zbernicová jednotka (STM32F0) zbiera dáta z dvoch prevodníkov HX711 a posiela ich na CAN zbernicu. Jednotky na zbernici sú prepojené telefónnym káblom ktorým su aj napájané. Na jednom z koncov zbernice sa nachádza Raspberry Pi 3 s rozšírením o CAN. Nazbierané dáta su posielané pomocou integrovaného WiFi modemu na webserver. Systém je napájaný z batérie nabíjanej solárnym panelom s dostatočným výkonom na nepretržitú prevádzku. Dáta su prezentované užívateľovi vo forme grafu na webovom rozhrani. Electronické váženie úlov nahradzuje aktuálne osobné meranie mechanickou váhou. Systém bol odtestovaný a nainštalovaný lokálnemu včelárovi.

Beehive Scale
Žilka, Martin ; Musil, Tomáš (referee) ; Novák, Lukáš (advisor)
The focus of this bachelor‘s thesis is to retrieve available information about possibilities of solution design of a beehive scale, which should be used in the countryside and has the option of remote data sending. The next step is to build a prototype of that scale. The introductory part contains a parameter description of eight types of commercial beehive scales. The next part is focused on principles, positives and negatives of some commercial weight sensors. The following section deals with communication interfaces used in the IoT. In conclusion is made a selection of the most appropriate technologies for remote weighing beehives, based on the previous research. The last part is devoted to the description of prototype construction.

Design of strain gauge devices for safety belts load measuring
Lontras, Martin ; Jebáček, Ivo (referee) ; Mališ, Michal (advisor)
The aim of this thesis is to design, produce and experimentally verified measuring device for measuring force in seatbelt, by using strain gages. First are discussed possibilities of measuring force by using device placed in between two parts of seat belt or in anchor point. These suggestions were not accepted for various reasons. Therefore is further described girder, which belt slightly deflected so that part of the load is transferred to the strain gauge measuring element. As default concept is choosen aluminum U-profile, in which is placed measuring mechanism. There are performed calculations of basic geometry and stress control. Then is described manufacturing and calibration on universal testing machine. In conclusion is realized measuring of the force in seat belt, which is loaded by shock force, occasioned by dropping weights from a certain height, which simulates the behavior of the belt and gauge during a crash test.

Measurement System For Determining Forces Acting On Loose Concrete Roof Paver
Mancl, Vlastimil
This paper introduces the topic of measuring the wind-induced forces on a concrete roof pavers. It describes the creation of a system, allowing such measurements and it also proposes two methods. First discussed method is measuring differential pressure. The second is measuring the weight of a roof paver. This article proved, that those methods can give meaningful results and that the future research should continue to use and improve this measurement system.
