Ultrazvukový anemometr

| Kategorie: Diplomové, bakalářské práce  | Tento dokument chci!

Práce popisuje principy a problémy při realizaci ultrazvukového anemometru. Je popsán princip výpočtu rychlosti větru a následné korekce výpočtu. Pro realizaci jsou využity ultrazvukové sensory a microcontrolér ARM Cortex-M3. Práce se zabývá generováním PWM signálu, jeho analogovou filtrací, zesílením a odvysíláním. Na přijímací straně jeto nízkonapěťový zesilovač a komparátor. Vyvíjený kód je popsán pomocí vývojového diagramu.

Poznámky redaktora

enjoyed Spanish warm climate and nature local people. Then familiarized with ultrasonic sensors and possibilities their usage. Sensors could be changed the another which includes transmitter and receiver one component. Great benefit this project was improved knowledge language and its usage in practice. programmed all the code language using driver library API with some checking assembler language. But still there are lot method how improve preciseness. Cortex-M3 Stellaris platform suitable for this application. I've get practice with few types operational amplifiers and comparator various connection. exclude error like m/s with obstacle between sensors. has much more potential, than used. Erasmus Valencia was great experience. Comparator should make interruption with lower reference and more advanced ADC input signal processing could included.CONCLUSION Technical From our aims successfully built axis works anemometer. Finally would like thank co-worker from Ireland and especially my director for his willingness solving problems. permit give know what exactly is processor doing some critical parts and let work reasonable complexity. Spanish speaking environment was considerable experience for well as writing English. 35 . Personal I've get know theoretical background and methods how construct anemometer. Basic amplitude and temperature corrections are included
