Chii chinonzi Passive Sensor?

Passive sensor inonziwo simba rekushandura sensor. Kufanana neInternet yezvinhu, haidi magetsi ekunze, ndiko kuti, inzwa isingade kushandisa simba rekunze, asi zvakare inogona kuwana simba kuburikidza nekunze sensor.

Isu tese tinoziva kuti masensa anogona kukamurwa kuita ma sensors ekubata, ma sensors emifananidzo, tembiricha sensors, motion sensors, chinzvimbo sensors, gasi sensors, light sensors uye kudzvanywa sensors zvichienderana nehuwandu hwemuviri hwekuona uye kuona. Kune passive sensors, iyo mwenje simba, electromagnetic mwaranzi, tembiricha, kufamba kwevanhu simba uye vibration sosi inowonekwa nemasensa ndiwo angangoita masimba.

Zvinonzwisisika kuti passive sensors inogona kupatsanurwa muzvikamu zvitatu zvinotevera: optical fiber passive sensor, surface acoustic wave passive sensor uye passive sensor yakavakirwa pane zvesimba.

• Optical fiber sensor

Optical fiber sensor imhando ye sensor yakavakirwa pane mamwe maitiro e optical fiber akagadzirwa pakati pemakore ekuma1970. Ichi chishandiso chinoshandura chimiro chakapimwa kuita chiratidzo chechiedza chinoyerwa. Iyo ine mwenje sosi, sensor, mwenje detector, chiratidzo chekugadzirisa dunhu uye optical fiber.

Iyo ine hunhu hwekunzwa kwakanyanya, yakasimba electromagnetic interference resistance, yakanaka kuvharisa magetsi, kuchinjika kwakasimba kwezvakatipoteredza, kuyerwa kure, kushandiswa kwesimba shoma, uye iri kuwedzera kukura mukushandiswa kweInternet yezvinhu. Semuenzaniso, iyo optical fiber hydrophone imhando yeinzwi sensor inotora iyo optical fiber sechinhu chinonzwisa tsitsi, uye optical fiber tembiricha sensor.

• Surface Acoustic Wave Sensor

Surface Acoustic Wave (SAW) sensor inzwa inoshandisa pamusoro acoustic wave mudziyo sechinhu chinonzwa. Ruzivo rwakayerwa runoratidzwa nekuchinja kwekumhanya kana kuwanda kwepamusoro acoustic wave muSURFACE acoustic wave mudziyo, uye inoshandurwa kuita yemagetsi chiratidzo chekubuda sensor. Iyo inzwa yakaoma ine huwandu hwakawanda hwema sensor. Iyo inonyanya kusanganisira pamusoro acoustic wave pressure sensor, pamusoro acoustic wave tembiricha sensor, pamusoro acoustic wave biological gene sensor, pamusoro acoustic wave kemikari gasi sensor uye yakangwara sensor, nezvimwe.

Kunze kweiyo passive optical fiber sensor ine yakakwira senitivity, inogona kuyerwa kureba, maitiro ekushomeka kwesimba, passive surface acoustic wave sensors anoshandisa Hui frequency shanduko fungidzira shanduko yevelocity, saka shanduko yecheki kuenda kuyero yekunze inogona kunge yakanyanya. chaiyo, panguva imwechete iyo hunhu hwevhoriyamu diki, huremu huremu, kuderera kwesimba rekushandisa kunogona kuita kuti iwane yakanaka yekupisa uye mechanical zvivakwa, Uye yakaunza nguva itsva yewireless, madiki sensors. Inoshandiswa zvakanyanya mune substation, chitima, aerospace uye mamwe minda.

• Passive Sensor Yakavakirwa pane Zvishandiso Zvemagetsi

Passive sensors yakavakirwa pazvinhu zvesimba, sezvinoreva zita, shandisa simba rakajairika muhupenyu kushandura simba remagetsi, senge simba rechiedza, kupisa simba, mechanical simba uye zvichingodaro. Iyo passive sensor yakavakirwa pazvinhu zvesimba ine zvakanakira bhendi yakakura, yakasimba anti-kupindira kugona, kushoma kukanganisa kune yakayerwa chinhu, yakanyanya kunzwisiswa, uye inoshandiswa zvakanyanya mumagetsi ekuyera minda senge yakakwira voltage, mheni, simba remwaranzi yemunda simba, high simba microwave uye zvichingodaro.

Kusanganiswa kwePassive Sensors nemamwe Tekinoroji

Mumunda weInternet weZvinhu, passive sensors ari kuwedzera uye zvakanyanya kushandiswa zvakanyanya, uye akasiyana marudzi epassive sensors akaburitswa. Semuenzaniso, masensa akasanganiswa neNFC, RFID uye kunyange wifi, Bluetooth, UWB, 5G uye humwe hutambo husina waya hwakazvarwa. mundangariro isiri-inotenderera, iyo inochengetwa kana simba risingapiwe.

Uye isina waya passive textile strain sensors yakavakirwa paRFID tekinoroji, Iyo inosanganisa RFID tekinoroji nezvinhu zvemachira kugadzira michina ine strain sensing basa. RFID textile strain sensor inotora kutaurirana uye induction modhi ye passive UHF RFID tag tekinoroji, inovimba nesimba remagetsi kushanda, ine miniaturization uye inoshanduka inogoneka, uye inova sarudzo inogona kupfeka inopfeka.

Pakupedzisira

Passive Internet yeZvinhu ndiyo ramangwana rekusimudzira nzira yeInternet yezvinhu. Sechinongedzo chepasirese Internet yezvinhu, izvo zvinodikanwa zvema sensors hazvichaganhurirwe kune diki uye yakaderera simba rekushandisa. Passive Internet yeZvinhu zvakare ichave nzira yekusimudzira yakakodzera kurima. Nekuenderera mberi kwekukura uye hunyanzvi hwepassive sensor tekinoroji, kushandiswa kwepassive sensor tekinoroji kuchave kwakawedzera.
