Chotenthetsera cha Crystal Cholamulidwa ndi Uvuni (OCXO)

Oven Controlled Crystal Oscillator (OCXO) ndi oscillator ya kristalo yomwe imagwiritsa ntchito thanki yotenthetsera yosasinthasintha kuti isunge kutentha kwa quartz crystal resonator mu crystal oscillator yosasinthasintha, ndipo kusintha kwa ma frequency otuluka a oscillator komwe kumachitika chifukwa cha kusintha kwa kutentha kwa ambient kumachepetsedwa pang'ono. OCXO imapangidwa ndi dera lowongolera kutentha kosasinthasintha ndi dera lowongolera kutentha, nthawi zambiri imagwiritsa ntchito "bridge" ya thermistor yopangidwa ndi differential series amplifier kuti ikwaniritse kuwongolera kutentha.

Ili ndi makhalidwe awa:

1. Kugwira ntchito bwino kwa kutentha: OCXO imakwaniritsa kubweza kutentha kwa oscillator pogwiritsa ntchito zinthu zowunikira kutentha ndi ma circuits okhazikika. Imatha kusunga kutulutsa kwa ma frequency kokhazikika pa kutentha kosiyanasiyana.
2. Kukhazikika kwa ma frequency ambiri: OCXO nthawi zambiri imakhala ndi kukhazikika kwa ma frequency molondola kwambiri, kusintha kwa ma frequency ake kumakhala kochepa komanso kokhazikika. Izi zimapangitsa kuti kukhazikika kwa ma frequency ambiri OCXO kukhale koyenera kugwiritsa ntchito ma frequency ambiri.
3. Nthawi yoyambira mwachangu: Nthawi yoyambira ya OCXO ndi yochepa, nthawi zambiri imakhala ma millisecond ochepa okha, zomwe zimatha kukhazikika mwachangu pafupipafupi yotulutsa.
4. Kugwiritsa ntchito mphamvu zochepa: Ma OCXO nthawi zambiri amagwiritsa ntchito mphamvu zochepa ndipo ndi oyenera kugwiritsa ntchito mphamvu zochepa, zomwe zingasunge mphamvu ya batri.

Kugwiritsa Ntchito Ma Oscillator a Crystal Olamulidwa ndi Uvuni:

1. Machitidwe olumikizirana: OCXO imagwiritsidwa ntchito kwambiri polumikizirana pafoni, kulumikizana ndi satelayiti, kutumiza deta opanda zingwe ndi zina kuti ipereke ma frequency okhazikika.
2. Makina oyendetsera malo ndi njira zoyendera: Mu mapulogalamu monga GPS ndi Beidou navigation System, OCXO imagwiritsidwa ntchito kupereka zizindikiro zolondola za wotchi, zomwe zimathandiza makinawo kuwerengera malo molondola komanso kuyeza nthawi.
3. Kukonza Zida: Mu zida zoyezera molondola, OCXO imagwiritsidwa ntchito kupereka zizindikiro zolondola za wotchi kuti zitsimikizire kulondola ndi kubwerezabwereza kwa zotsatira za kuyeza.
4. Zipangizo zamagetsi: OCXO imagwiritsidwa ntchito kwambiri mu wotchi ya zida zamagetsi kuti ipereke ma frequency okhazikika a wotchi kuti chipangizocho chigwire ntchito bwino.

Mwachidule, OCXO ili ndi makhalidwe monga kugwira ntchito bwino kwa kutentha, kukhazikika kwa ma frequency ambiri, nthawi yoyambira mwachangu komanso kugwiritsa ntchito mphamvu zochepa, zomwe ndizoyenera kugwiritsa ntchito mapulogalamu omwe amafunikira ma frequency ambiri komanso omwe amakhudzidwa ndi kusintha kwa kutentha.
