Passive Sensor yog dab tsi?

Lub sensor passive tseem hu ua lub sensor hloov pauv zog. Ib yam li Internet of Things, nws tsis xav tau lub zog sab nraud, uas yog, nws yog lub sensor uas tsis tas yuav siv lub zog sab nraud, tab sis kuj tuaj yeem tau txais lub zog los ntawm lub sensor sab nraud.

Peb txhua tus paub tias cov sensors muaj peev xwm muab faib ua cov sensors kov, cov sensors duab, cov sensors kub, cov sensors txav mus los, cov sensors txoj hauj lwm, cov sensors roj, cov sensors lub teeb thiab cov sensors siab raws li qhov sib txawv ntawm kev pom thiab kev ntes. Rau cov sensors passive, lub zog lub teeb, hluav taws xob electromagnetic, kub, lub zog txav mus los ntawm tib neeg thiab kev co uas cov sensors ntes tau yog cov peev xwm zog.

Nws nkag siab tias cov sensors passive tuaj yeem muab faib ua peb pawg hauv qab no: optical fiber passive sensor, surface acoustic wave passive sensor thiab passive sensor raws li cov khoom siv zog.

• Lub sensor fiber ntau

Lub sensor fiber ntau yog ib hom sensor raws li qee yam ntxwv ntawm cov fiber ntau tsim nyob rau nruab nrab xyoo 1970. Nws yog ib lub cuab yeej uas hloov lub xeev ntsuas mus rau hauv lub teeb liab ntsuas tau. Nws muaj lub teeb ci, lub sensor, lub teeb ntes, lub voj voog teeb liab thiab cov fiber ntau.

Nws muaj cov yam ntxwv ntawm kev rhiab heev, muaj zog tiv thaiv hluav taws xob cuam tshuam, rwb thaiv hluav taws xob zoo, kev hloov pauv ib puag ncig zoo, kev ntsuas deb, kev siv hluav taws xob tsawg, thiab nws tau loj hlob zuj zus hauv kev siv Is Taws Nem ntawm yam. Piv txwv li, lub tshuab hluav taws xob fiber ntau yog ib hom sensor suab uas siv lub fiber ntau ua lub ntsiab lus rhiab heev, thiab lub sensor kub ntawm lub fiber ntau.

• Lub Sensor Wave Acoustic Surface

Lub sensor hu ua Surface Acoustic Wave (SAW) yog ib lub sensor uas siv lub surface acoustic wave ua lub sensor. Cov ntaub ntawv ntsuas tau pom los ntawm kev hloov pauv ntawm qhov ceev lossis zaus ntawm surface acoustic wave hauv lub SURFACE acoustic wave device, thiab hloov mus ua lub sensor tso zis hluav taws xob. Nws yog ib lub sensor nyuaj nrog ntau yam sensors. Nws feem ntau suav nrog lub sensor ntsuas siab ntawm surface acoustic wave, lub sensor ntsuas kub ntawm surface acoustic wave, lub sensor ntsuas noob caj noob ces ntawm surface acoustic wave, lub sensor ntsuas roj tshuaj lom neeg ntawm surface acoustic wave thiab lub sensor ntse, thiab lwm yam.

Dhau li ntawm lub passive optical fiber sensor nrog siab rhiab heev, tuaj yeem ntsuas qhov deb, cov yam ntxwv ntawm kev siv hluav taws xob tsawg, passive surface acoustic wave sensors siv Hui zaus hloov kwv yees qhov kev hloov pauv ntawm qhov ceev, yog li qhov kev hloov pauv ntawm qhov kev kuaj xyuas mus rau sab nraud ntsuas tuaj yeem ua tau zoo heev, tib lub sijhawm nws cov yam ntxwv ntawm qhov me me, lub teeb yuag, kev siv hluav taws xob tsawg tuaj yeem cia nws tau txais cov khoom siv thermal thiab mechanical zoo, Thiab coj mus rau hauv lub sijhawm tshiab ntawm wireless, me me sensors. Nws yog dav siv hauv substation, tsheb ciav hlau, aerospace thiab lwm yam teb.

• Passive Sensor Raws Li Cov Khoom Siv Zog

Cov khoom siv hluav taws xob passive uas siv cov khoom siv hluav taws xob, raws li lub npe qhia, siv lub zog niaj hnub hauv lub neej los hloov lub zog hluav taws xob, xws li lub zog teeb, lub zog cua sov, lub zog kho tshuab thiab lwm yam. Lub passive sensor uas siv cov khoom siv hluav taws xob muaj qhov zoo ntawm qhov dav dav, muaj peev xwm tiv thaiv kev cuam tshuam zoo, cuam tshuam tsawg kawg nkaus rau cov khoom ntsuas, muaj kev nkag siab zoo, thiab siv dav hauv kev ntsuas hluav taws xob xws li hluav taws xob siab, xob laim, lub zog hluav taws xob muaj zog, microwave muaj zog siab thiab lwm yam.

Kev sib xyaw ua ke ntawm Passive Sensors nrog lwm yam thev naus laus zis

Hauv thaj chaw ntawm Is Taws Nem ntawm Yam, cov khoom siv passive sensors tau siv ntau dua thiab ntau dua, thiab ntau hom passive sensors tau luam tawm. Piv txwv li, cov sensors ua ke nrog NFC, RFID thiab txawm tias wifi, Bluetooth, UWB, 5G thiab lwm yam wireless technologies tau yug los. Hauv hom passive, lub sensor tau txais lub zog los ntawm cov teeb liab xov tooj cua hauv ib puag ncig los ntawm lub antenna, thiab cov ntaub ntawv sensor khaws cia rau hauv lub cim xeeb tsis hloov pauv, uas khaws cia thaum tsis muaj hluav taws xob.

Thiab wireless passive textile strain sensors raws li RFID technology, Nws ua ke RFID technology nrog textile cov ntaub ntawv los tsim cov khoom siv nrog strain sensing function. RFID textile strain sensor siv kev sib txuas lus thiab induction hom ntawm passive UHF RFID tag technology, vam khom lub zog electromagnetic los ua haujlwm, muaj miniaturization thiab flexibility peev xwm, thiab dhau los ua qhov kev xaiv ntawm cov khoom siv hnav tau.

Thaum kawg

Kev Siv Internet Tsis Siv Neeg (Passive Internet of Things) yog txoj kev loj hlob yav tom ntej ntawm Internet of Things. Ua ib qho kev sib txuas ntawm passive Internet of Things, qhov yuav tsum tau ua rau cov sensors tsis txwv rau qhov me me thiab siv hluav taws xob tsawg lawm. Passive Internet of Things kuj tseem yuav yog txoj kev loj hlob uas tsim nyog cog qoob loo ntxiv. Nrog rau kev loj hlob tas mus li thiab kev tsim kho tshiab ntawm passive sensor technology, kev siv passive sensor technology yuav dav dua.
