Yintoni iPassive Sensor?

I-sensor engasebenziyo ikwabizwa ngokuba yi-energy conversion sensor. Njenge-Internet of Things, ayidingi mbane wangaphandle, oko kukuthi, yi-sensor engadingi mbane wangaphandle, kodwa ikwanokufumana amandla nge-sensor yangaphandle.

Sonke siyazi ukuba izinzwa zinokwahlulwa zibe zizinzwa zokuchukumisa, izinzwa zomfanekiso, izinzwa zobushushu, izinzwa zokuhamba, izinzwa zendawo, izinzwa zegesi, izinzwa zokukhanya kunye nezinzwa zoxinzelelo ngokwemilinganiselo eyahlukeneyo yokuqonda kunye nokufumanisa. Kwiizinzwa ezingasebenziyo, amandla okukhanya, imitha ye-electromagnetic, ubushushu, amandla okunyakaza komntu kunye nomthombo wokungcangcazela ofunyenwe zizinzwa zizinto ezinokubakho njengemithombo yamandla.

Kuyaqondakala ukuba ii-sensors ezingasebenziyo zinokwahlulwa zibe ziindidi ezintathu ezilandelayo: i-optical fiber passive sensor, i-surface acoustic wave passive sensor kunye ne-passive sensor esekelwe kwizixhobo zamandla.

• Inzwa yefayibha yokubonisa

I-optical fiber sensor luhlobo lwe-sensor olusekelwe kwiimpawu ezithile ze-optical fiber ezaphuhliswa phakathi kweminyaka yoo-1970. Sisixhobo esiguqula imeko elinganisiweyo ibe yisignali yokukhanya enokulinganiswa. Iquka umthombo wokukhanya, i-sensor, i-light detector, i-signal conditioning circuit kunye ne-optical fiber.

Ineempawu zokuba novakalelo oluphezulu, ukumelana nokuphazamiseka kwe-electromagnetic okunamandla, ubushushu obuhle bombane, ukuziqhelanisa okunamandla nokusingqongileyo, ukulinganisa okukude, ukusetyenziswa kwamandla aphantsi, kwaye ikhula ngakumbi ekusebenziseni i-Intanethi yezinto. Umzekelo, i-hydrophone yefayibha ye-optical luhlobo lwe-sensor yesandi ethatha i-optical fiber njengento ebuthathaka, kunye ne-sensor yobushushu befayibha ye-optical.

• Isivamvo seWave yeAcoustic ephezulu

I-Surface Acoustic Wave (SAW) sensor yi-sensor esebenzisa isixhobo se-surface acoustic wave njengento yokuva. Ulwazi olulinganisiweyo lubonakaliswa kukutshintsha kwesantya okanye i-frequency ye-surface acoustic wave kwisixhobo se-SURFACE acoustic wave, kwaye iguqulwa ibe yi-electrical signal output sensor. Yi-sensor eyinkimbinkimbi enoluhlu olubanzi lwee-sensors. Ibandakanya ikakhulu i-surface acoustic wave pressure sensor, i-surface acoustic wave temperature sensor, i-surface acoustic wave biological gene sensor, i-surface acoustic wave chemical gas sensor kunye ne-intelligent sensor, njl.njl.

Ngaphandle kwe-sensor yefayibha ye-optical engasebenziyo enovakalelo oluphezulu, umlinganiselo womgama ungalinganiswa, iimpawu zokusetyenziswa kwamandla aphantsi, ii-sensor ze-acoustic wave ezingasebenziyo zisebenzisa utshintsho lwe-frequency ye-Hui ukuqikelela utshintsho lwesantya, ngoko ke utshintsho lokujonga umlinganiselo wangaphandle lunokuba ngokuchanekileyo kakhulu, kwangaxeshanye iimpawu zomthamo omncinci, ubunzima obuphantsi, ukusetyenziswa kwamandla aphantsi kunokwenza ukuba ifumane iipropati ezilungileyo zobushushu kunye noomatshini, kwaye yazisa ixesha elitsha lee-sensors ezingenazingcingo, ezincinci. Isetyenziswa kakhulu kwi-substation, kuloliwe, kwi-aerospace nakwezinye iindawo.

• Isivamvo esingasebenziyo esisekelwe kwizixhobo zamandla

Izinzwa ezingasebenziyo ezisekelwe kwizixhobo zamandla, njengoko igama lisitsho, zisebenzisa amandla aqhelekileyo ebomini ukuguqula amandla ombane, njengamandla okukhanya, amandla obushushu, amandla oomatshini njalo njalo. Isinzwa esingasebenziyo esisekelwe kwizixhobo zamandla sineengenelo zebhendi ebanzi, amandla aqinileyo okulwa nokuphazamiseka, ukuphazamiseka okuncinci kwinto elinganisiweyo, uvakalelo oluphezulu, kwaye sisetyenziswa kakhulu kwiindawo zokulinganisa i-electromagnetic ezifana ne-voltage ephezulu, umbane, amandla entsimi yemitha enamandla, i-microwave enamandla aphezulu njalo njalo.

Ukudibana kweeSensors ezingasebenziyo nezinye iiTekhnoloji

Kwicandelo le-Intanethi yezinto, ii-sensors ezingasebenziyo ziya zisetyenziswa kakhulu, kwaye iintlobo ngeentlobo zee-sensors ezingasebenziyo ziye zapapashwa. Umzekelo, ii-sensors ezidityaniswe ne-NFC, i-RFID kunye ne-wifi, i-Bluetooth, i-UWB, i-5G kunye nezinye iiteknoloji ezingenazingcingo ziye zazalwa. Kwimo ye-passive, i-sensor ifumana amandla kwiisignali zerediyo kwindalo esingqongileyo nge-antenna, kwaye idatha ye-sensor igcinwa kwimemori engaguqukiyo, egcinwa xa umbane unganikezelwanga.

Kwaye izinzwa zoxinzelelo lwelaphu ezingenazingcingo ezisekelwe kwitekhnoloji yeRFID, Idibanisa itekhnoloji yeRFID kunye nezixhobo zelaphu ukwenza izixhobo ezinomsebenzi wokuvavanya uxinzelelo. Isenzi soxinzelelo lwelaphu seRFID sisebenzisa indlela yonxibelelwano kunye nokungenisa ubuchwepheshe bethegi ye-UHF RFID tag, sixhomekeke kumandla ombane ukuze sisebenze, sinamandla amancinci kunye nokuguquguquka, kwaye siba lukhetho olunokwenzeka lwezixhobo ezinokunxitywa.

Ekugqibeleni

I-Passive Internet of Things yindlela yophuhliso lwexesha elizayo lwe-Intanethi yezinto. Njengekhonkco le-passive Internet of Things, iimfuno zeesensa azisekho kuphela ekusebenziseni amandla amancinci kunye namandla aphantsi. I-Passive Internet of Things nayo iya kuba yindlela yophuhliso efanele ukukhuliswa ngakumbi. Ngokukhula okuqhubekayo kunye nobuchule betekhnoloji ye-passive sensor, ukusetyenziswa kwetekhnoloji ye-passive sensor kuya kuba kubanzi ngakumbi.
