Yintoni iPassive Sensor?

Uluvo lwePassive lukwabizwa ngokuba yinzwa yokuguqula amandla. Njenge-Intanethi yeZinto, ayifuni ukunikezelwa kwamandla angaphandle, oko kukuthi, inzwa engadingi ukusebenzisa amandla angaphandle, kodwa inokufumana amandla ngokusebenzisa inzwa yangaphandle.

Sonke siyazi ukuba abenzi boluvo banokwahlulwa babe ngabenzi boluvo, iinzwa zemifanekiso, iinzwa zeqondo lobushushu, iinzwa ezishukumayo, iinzwa zemo, iinzwa zerhasi, iinzwa zokukhanya kunye nezinzwa zoxinzelelo ngokwemiba eyahlukeneyo yomzimba yokubona kunye nokufumanisa. Kwizinzwa zoluvo, amandla okukhanya, imitha ye-electromagnetic, iqondo lobushushu, amandla entshukumo yomntu kunye nomthombo wokungcangcazela ofunyenwe zizivamvo yimithombo yamandla enokubakho.

Kuyaqondwa ukuba abenzi boluvo bangohlulwa ngokwezi ndidi zintathu zilandelayo: i-optical fiber passive sensor, i-surface acoustic wave passive sensor kunye ne-passive sensor esekwe kwimathiriyeli yamandla.

• Isivamvo sefiber ye-Optical

I-Optical fiber sensor luhlobo lwenzwa esekelwe kwiimpawu ezithile zefiber optical eziphuhliswe phakathi koo-1970. Sisixhobo esiguqula isimo esilinganisiweyo sibe ngumqondiso wokukhanya onokulinganiswa. Iqukethe umthombo wokukhanya, inzwa, i-detector yokukhanya, i-signal conditioning circuit circuit kunye ne-fiber optical.

Ineempawu zobuntununtunu obuphezulu, ukuxhathisa okunamandla kokuphazamiseka kombane, ukugqunywa kombane okulungileyo, ukuziqhelanisa nokusingqongileyo okuqinileyo, umlinganiselo okude, ukusetyenziswa kwamandla aphantsi, kwaye iya ikhula ngokukhula ekusebenziseni i-Intanethi yezinto. Umzekelo, i-fiber optical hydrophone luhlobo lwenzwa yesandi ethatha i-fiber optical njengento ebuthathaka, kunye ne-optical fibre yeqondo lokushisa.

• Umphezulu weAcoustic Wave Sensor

Isivamvo se-Surface Acoustic Wave (SAW) sisivamvo esisebenzisa isixhobo somphezulu we-acoustic wave njengesixhobo sokuva. Ulwazi olulinganisiweyo lubonakaliswe kukutshintsha kwesantya okanye ukuphindaphinda kwamaza omsindo we-acoustic kwisixhobo se-acoustic wave ye-SURFACE, kwaye iguqulwa ibe yinzwa yokuphuma kombane. Yinzwa eyinkimbinkimbi kunye noluhlu olubanzi lweenzwa. Ibandakanya ubukhulu becala inzwa yoxinzelelo lwe-acoustic wave, inzwa yobushushu bomphezulu we-acoustic wave, i-surface acoustic wave biological gene sensor, i-surface acoustic wave chemical sensor yegesi kunye nesensom ekrelekrele, njl.

Ngaphandle kwesivamvo sefiber ebonakalayo enovakalelo oluphezulu, inokulinganisa umgama, iimpawu zokusetyenziswa kwamandla aphantsi, abenzi boluvo be-acoustic wave basebenzisa i-Hui frequency change guess the change of velocity, ngoko ke utshintsho lwetshekhi ukuya kumlinganiselo wangaphandle lunokuba lukhulu. ichanekile, kwangaxeshanye iimpawu zomthamo omncinci, ubunzima obulula, ukusetyenziswa kwamandla aphantsi kunokuwuvumela ukuba ufumane iipropathi ezilungileyo ze-thermal kunye noomatshini, kwaye ungenise ixesha elitsha le-wireless, izinzwa ezincinci. Isetyenziswa kakhulu kwisikhululo esingaphantsi, uloliwe, i-aerospace kunye namanye amabala.

• Isivamvo sePassive esekwe kwiMathiriyeli yaMandla

I-sensor passive esekelwe kwizinto zamandla, njengoko igama lithetha, sebenzisa amandla aqhelekileyo ebomini ukuguqula amandla ombane, njengamandla okukhanya, amandla okushisa, amandla omatshini kunye nokunye. I-sensor ye-passive esekwe kwizixhobo zamandla inezibonelelo zebhendi ebanzi, amandla okumelana nokuphazamiseka, ukuphazamiseka okuncinci kwinto elinganisiweyo, ubuntununtunu obuphezulu, kwaye isetyenziswa ngokubanzi kwimimandla yokulinganisa i-electromagnetic efana nombane ophezulu, umbane, amandla entsimi yeradiation enamandla, amandla aphezulu e-microwave njalo njalo.

Ukudityaniswa kwe-Passive Sensors kunye nezinye iiTechnologies

Kwintsimi ye-Intanethi yeZinto, izinzwa ezisetyenziswayo zisetyenziswa ngokubanzi nangakumbi, kwaye iintlobo ngeentlobo zezivamvo zokwenziwa ziye zapapashwa. Ngokomzekelo, i-sensor edibeneyo kunye ne-NFC, i-RFID kunye ne-wifi, i-Bluetooth, i-UWB, i-5G kunye nezinye i-teknoloji ezingenazintambo ziye zazalwa. kwinkumbulo engaguquguqukiyo, egcinwayo xa amandla engabonelelwanga.

Kunye ne-wireless passive textile strain sensors esekwe kwitekhnoloji yeRFID, Idibanisa itekhnoloji yeRFID nezinto ezilukiweyo ukwenza izixhobo ezinomsebenzi wokuva ubunzima. Isivamvo se-RFID soxinaniso lwelaphu sisebenzisa unxibelelwano kunye nemowudi yokungeniswa yetekhnoloji yethegi ye-UHF RFID, ixhomekeke kumandla we-electromagnetic ukusebenza, ine-miniaturization kunye nokuguquguquka okunokubakho, kwaye ibe lukhetho olunokubakho lwezixhobo ezinokunxitywa.

Ekugqibeleni

I-Intanethi yePassive yeZinto lukhokelo lophuhliso lwekamva lwe-Intanethi yeZinto. Njengekhonkco le-Intanethi yeZinto, iimfuno zezivamvo azisekho kuncinci kunye nokusetyenziswa kwamandla aphantsi. I-Intanethi ye-Passive yeZinto nayo iya kuba ngumkhombandlela wophuhliso ofanele ukulinywa ngakumbi. Ngokukhula okuqhubekayo kunye nokutsha kweteknoloji ye-sensor ye-passive, ukusetyenziswa kweteknoloji ye-sensor ye-passive kuya kuba kuninzi.
