Passive Sensor yog dab tsi?

Passive sensor tseem hu ua lub zog hloov pauv sensor.Zoo li Is Taws Nem ntawm Yam, nws tsis xav tau lub zog hluav taws xob sab nraud, uas yog, nws yog lub ntsuas hluav taws xob uas tsis tas yuav siv hluav taws xob sab nraud, tab sis kuj tuaj yeem tau txais lub zog los ntawm sab nraud sensor.

Peb txhua tus paub tias cov sensors tuaj yeem muab faib ua cov sensors kov, cov duab sensors, ntsuas kub, ntsuas qhov ntsuas, ntsuas qhov ntsuas, ntsuas roj, lub teeb sensors thiab siab sensors raws li qhov sib txawv ntawm lub cev ntawm kev nkag siab thiab nrhiav kom pom.Rau passive sensors, lub teeb lub zog, hluav taws xob hluav taws xob hluav taws xob, qhov kub thiab txias, tib neeg lub zog txav thiab kev vibration qhov chaw kuaj pom los ntawm cov sensors yog lub peev xwm lub zog.

Nws tau nkag siab tias passive sensors tuaj yeem muab faib ua peb pawg hauv qab no: optical fiber passive sensor, nto acoustic yoj passive sensor thiab passive sensor raws li cov khoom siv hluav taws xob.

• Optical fiber ntau sensor

Optical fiber ntau sensor yog ib hom sensor raws li ib co yam ntxwv ntawm optical fiber ntau tsim nyob rau hauv nruab nrab xyoo 1970s.Nws yog ib qho khoom siv uas hloov lub xeev ntsuas mus rau hauv lub teeb liab ntsuas.Nws muaj lub teeb ci, sensor, lub teeb pom kev, teeb liab txias Circuit Court thiab fiber ntau optical.

Nws muaj cov yam ntxwv ntawm siab rhiab heev, muaj zog electromagnetic cuam tshuam tsis kam, zoo hluav taws xob rwb thaiv tsev, muaj zog ib puag ncig adaptation, tej thaj chaw deb ntsuas, tsawg zog noj, thiab yog nce mature nyob rau hauv daim ntawv thov ntawm Internet ntawm tej yam.Piv txwv li, optical fiber hydrophone yog ib yam ntawm lub suab sensor uas siv lub optical fiber ua ib tug rhiab ntsiab, thiab lub optical fiber kub sensor.

• Nto Acoustic Wave Sensor

Surface Acoustic Wave (SAW) sensor yog ib qho sensor uas siv lub tshuab acoustic yoj saum npoo raws li qhov ntsuas qhov ntsuas.Cov ntaub ntawv ntsuas tau cuam tshuam los ntawm kev hloov pauv ntawm qhov nrawm lossis zaus ntawm qhov chaw acoustic nthwv dej hauv SURFACE acoustic yoj ntaus ntawv, thiab hloov mus rau hauv lub teeb liab hluav taws xob tso zis sensor.Nws yog ib tug complex sensor nrog ntau yam ntawm sensors.Nws feem ntau suav nrog nto acoustic yoj siab sensor, nto acoustic nthwv dej kub sensor, nto acoustic yoj biological gene sensor, nto acoustic yoj chemical gas sensor thiab ntse sensor, thiab lwm yam.

Dhau li ntawm qhov passive optical fiber ntau sensor nrog siab rhiab heev, tuaj yeem ntsuas qhov deb, cov yam ntxwv ntawm kev siv hluav taws xob tsawg, passive nto acoustic yoj sensors siv Hui zaus hloov twv qhov kev hloov ntawm kev tshaj tawm, yog li qhov kev hloov ntawm daim tshev mus rau sab nraud ntsuas yuav ua tau heev. meej, nyob rau tib lub sij hawm nws cov yam ntxwv ntawm me me ntim, lub teeb yuag, tsawg zog noj yuav cia nws tau zoo thermal thiab mechanical zog, thiab ushered nyob rau hauv ib tug tshiab era ntawm wireless, me me sensors.Nws yog dav siv nyob rau hauv substation, tsheb ciav hlau, aerospace thiab lwm yam teb.

• Passive Sensor Raws li cov khoom siv hluav taws xob

Passive sensors raws li cov khoom siv hluav taws xob, raws li lub npe qhia, siv lub zog siv hauv lub neej los hloov hluav taws xob, xws li lub teeb lub zog, lub zog hluav taws xob, lub zog hluav taws xob thiab lwm yam.Lub passive sensor raws li cov khoom siv hluav taws xob muaj qhov zoo ntawm qhov dav dav, muaj peev xwm tiv thaiv kev cuam tshuam, kev cuam tshuam tsawg heev rau cov khoom ntsuas, siab rhiab heev, thiab yog siv dav hauv kev ntsuas hluav taws xob xws li hluav taws xob, hluav taws xob, hluav taws xob muaj zog, siab zog microwave thiab lwm yam.

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

Nyob rau hauv lub tshav pob ntawm Is Taws Nem ntawm Yam, passive sensors yog ntau thiab ntau lug siv, thiab ntau yam passive sensors tau luam tawm.Piv txwv li, sensors ua ke nrog NFC, RFID thiab txawm wifi, Bluetooth, UWB, 5G thiab lwm yam wireless technologies tau yug los.Hauv hom passive, lub sensor tau txais lub zog los ntawm xov tooj cua teeb liab hauv ib puag ncig los ntawm tus kav hlau txais xov, thiab cov ntaub ntawv sensor tau khaws cia. nyob rau hauv lub cim xeeb uas tsis yog-volatile, uas yog khaws cia thaum lub hwj chim tsis muab.

Thiab wireless passive textile strain sensors raws li RFID thev naus laus zis, Nws txuas nrog RFID thev naus laus zis nrog cov ntaub ntawv textile los tsim cov khoom siv nrog kev paub txog kev ua haujlwm.RFID textile strain sensor txais kev sib txuas lus thiab induction hom passive UHF RFID tag thev naus laus zis, tso siab rau lub zog hluav taws xob ua haujlwm, muaj peev xwm ua haujlwm me me thiab yooj yim, thiab dhau los ua qhov kev xaiv ntawm cov khoom siv hnav.

Thaum kawg

Passive Internet ntawm Yam yog qhov kev txhim kho yav tom ntej ntawm Internet ntawm Yam.Raws li qhov txuas ntawm passive Internet ntawm Yam, cov kev xav tau rau cov sensors tsis txwv rau cov khoom me me thiab kev siv hluav taws xob tsawg.Passive Internet ntawm Yam tseem yuav yog txoj kev txhim kho tsim nyog ntxiv rau kev cog qoob loo.Nrog rau kev loj hlob tas mus li thiab kev tsim kho tshiab ntawm passive sensor technology, daim ntawv thov ntawm passive sensor technology yuav ntau dua.
