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

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