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

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