Chii chinonzi Passive Sensor?

Sensor isingashande inonziwo sensor yekushandura simba. Kufanana neInternet of Things, haidi simba rekunze, kureva kuti, i sensor isingade kushandisa simba rekunze, asi inogonawo kuwana simba kuburikidza ne sensor yekunze.

Tose tinoziva kuti masensa anogona kukamurwa kuita masensa ekubata, masensa emifananidzo, masensa ekupisa, masensa ekufamba, masensa enzvimbo, masensa egasi, masensa echiedza uye masensa ekumanikidza zvichienderana nehuwandu hwakasiyana hwekuona uye kuona. Kune masensa asingashande, simba rechiedza, mwaranzi yemagetsi, tembiricha, simba rekufamba kwevanhu uye sosi yekudedera inowanikwa nemasensa ndiwo masosi esimba anogona kuwanikwa.

Zvinonzwisisika kuti masensa asingashande anogona kukamurwa muzvikamu zvitatu zvinotevera: sensor isingashande ye optical fiber, sensor isingashande ye surface acoustic wave uye sensor isingashande yakavakirwa pazvinhu zvine simba.

• Sensor yefaibha ye optical

Chinongedzo chefiber che optical imhando ye sensor yakavakirwa pane zvimwe zvinhu zve fiber ye optical yakagadzirwa pakati pemakore ekuma1970. Ichi chishandiso chinoshandura mamiriro akayerwa kuita chiratidzo chechiedza chinoyerwa. Chinosanganisira chiedza chinobva, sensor, light detector, signal conditioning circuit uye fiber ye optical.

Ine hunhu hwekunzwa kwakanyanya, kuramba kupindira kwemagetsi zvakanyanya, kudzivirira kupisa kwemagetsi zvakanaka, kugadzirisa nharaunda kwakasimba, kuyerwa kure, kushandisa simba shoma, uye iri kukura zvakanyanya mukushandiswa kweInternet yezvinhu. Semuenzaniso, optical fiber hydrophone rudzi rwe sensor yeruzha inotora optical fiber sechinhu chinonzwisisika, uye optical fiber temperature sensor.

• Sensor yeAcoustic Wave yepamusoro

Sensor yeSurface Acoustic Wave (SAW) isensorer inoshandisa mudziyo weacoustic wave sechinhu chinoona. Ruzivo rwakayerwa rwunoratidzwa nekuchinja kwekumhanya kana frequency yeacoustic wave pamusoro pechinhu cheSURFACE acoustic wave, uye inoshandurwa kuita sensor yemagetsi inoburitsa masaini. Isensorer yakaoma ine masensor akasiyana-siyana. Inonyanya kusanganisira surface acoustic wave pressure sensor, surface acoustic wave temperature sensor, surface acoustic wave biological gene sensor, surface acoustic wave chemical gas sensor uye intelligent sensor, nezvimwewo.

Kunze kwe sensor ye passive optical fiber ine high sensitivity, inogona kuyerwa kure, hunhu hwesimba shoma rinoshandiswa, sensor ye acoustic wave sensors inoshandisa Hui frequency change inofungidzira shanduko yespeed, saka shanduko yekutarisa kuyerwa kwekunze inogona kuve yakanyatsojeka, panguva imwe chete hunhu hwevhoriyamu diki, huremu hwakareruka, simba shoma rinoshandiswa zvinogona kuita kuti iwane hunhu hwakanaka hwekupisa uye hwemakanika, uye yakaunza nguva itsva yemasensa madiki asina waya. Inoshandiswa zvakanyanya mu substation, chitima, aerospace nedzimwe nzvimbo.

• Sensor Isingashande Yakavakirwa Pazvinhu Zvesimba

Sensors dzisingashande dzakavakirwa pazvinhu zvine simba, sezita rayo, dzinoshandisa simba rakajairika muhupenyu kushandura simba remagetsi, senge simba rechiedza, simba rekupisa, simba remakanika nezvimwewo. Sensor isingashande yakavakirwa pazvinhu zvine simba ine zvakanakira zvebhandi rakakura, kugona kwakasimba kwekudzivirira kukanganiswa, kukanganiswa kushoma kwechinhu chakayerwa, kunzwa kwakanyanya, uye inoshandiswa zvakanyanya muminda yekuyera magineti senge voltage yakakwira, mheni, simba remunda remwaranzi rakasimba, microwave ine simba rakawanda nezvimwewo.

Kusanganiswa kwePassive Sensors nedzimwe Tekinoroji

Mundima yeInternet of Things, ma sensor asingashande (passive sensors) ari kushandiswa zvakanyanya, uye mhando dzakasiyana dzema sensor asingashande (passive sensors) dzakabudiswa. Semuenzaniso, ma sensors akasanganiswa neNFC, RFID uye kunyange wifi, Bluetooth, UWB, 5G nedzimwe nzira dzemagetsi dzisina waya dzakatanga kushandiswa. Mu passive mode, sensor inowana simba kubva kumasaini eredhiyo ari munharaunda kuburikidza neantenna, uye data re sensor rinochengetwa mu non-volatile memory, iyo inochengetwa kana simba risingapihwe.

Uye ma sensor eRFID asingashandise waya anoshandiswa pakugadzira michina ine basa rekuona kusvuta. RFID textile strain sensor inoshandisa nzira yekutaurirana uye induction ye passive UHF RFID tag technology, inoshandisa simba remagetsi kuti ishande, ine simba rekuita kuti zvinhu zvisanyanya kuomarara uye zvisanyanya kushata, uye inova sarudzo yemidziyo inopfekwa.

Pakupera

Passive Internet of Things ndiyo nzira yekuvandudza Indaneti yeZvinhu mune ramangwana. Sechisungo cheInternet of Things isingashande, zvinodiwa zvemasensa hazvichagumiri pakushandisa simba shoma uye simba shoma. Passive Internet of Things ichavewo nzira yekuvandudza inofanirwa kukudziridzwa zvakanyanya. Nekukura kuri kuramba kuchienderera mberi uye kuvandudzwa kwetekinoroji yepassive sensor, kushandiswa kwetekinoroji yepassive sensor kuchawedzera.
