Strain measurement system
Novotný, Jan ; Fedra, Zbyněk (referee) ; Štohanzl, Milan (advisor)
The batchelor thesis is focused on the design of strain measurement system using a metal resistance strain gages. Measured analog quantity is converted to digital form and sent to microcontroller, where the quantity is adapted and then display. The first part of project looks into genesis of different types of mechanical stresses, principles of resistance strain gages, the types of measurement bridges, theory of analog-to-digital conversion and short description of used microcontroller and liquid-crystal display. There are wiring diagram of the system and printed circuit boards designed in the second part of project. System can be also calibrated and driven by PC using Universal Asynchronous Communication Interface. System is physical realized, its functions are checked and there is subscribed driving of the system. Finally other alternatives of improving properties of the system are analyzed due to posibility of using of the system in practical aplications.
