Passive Sensor ke eng?

Passive sensor e boetse e bitsoa sensor ea matla a ho fetola matla. Joalo ka Marang-rang a Lintho, ha e hloke phepelo ea matla a kantle, ke hore, ke sensor e sa hlokeng ho sebelisa matla a kantle, empa hape e ka fumana matla ka sensor ea kantle.

Kaofela rea ​​tseba hore li-sensor li ka aroloa ka li-sensors tsa ho ama, li-sensor tsa setšoantšo, li-sensors tsa mocheso, li-motion sensors, li-sensors tsa boemo, li-gas sensors, li-sensor tsa leseli le li-sensor tsa khatello ho latela boholo bo fapaneng ba 'mele ba ho lemoha le ho lemoha. Bakeng sa li-sensor tse sa sebetseng, matla a khanya, mahlaseli a motlakase, mocheso, matla a ho sisinyeha ha motho le mohloli oa vibrate o bonoang ke li-sensor ke mehloli ea matla e ka bang teng.

Ho utloisisoa hore li-sensor tsa passive li ka aroloa ka mekhahlelo e meraro e latelang: optical fiber passive sensor, surface acoustic wave passive sensor le passive sensor e thehiloeng lisebelisoa tsa matla.

• Sensor ea fiber ea optic

Optical fiber sensor ke mofuta oa kutlo o ipapisitseng le litšobotsi tse ling tsa fiber ea optical e ntlafalitsoeng bohareng ba lilemo tsa bo-1970. Ke sesebelisoa se fetolang boemo bo lekantsoeng hore e be lets'oao la leseli le lekanyang. E na le mohloli oa leseli, sensor, detector ea leseli, potoloho ea boemo ba matšoao le fiber ea optical.

E na le litšoaneleho tsa kutlo e phahameng, khanyetso e matla ea ho kena-kenana le motlakase, ho kenya motlakase hantle, ho ikamahanya le maemo ho matla a tikoloho, tekanyo e hole, tšebeliso e tlase ea matla, 'me e ntse e hola ka ho fetesisa ts'ebelisong ea Marang-rang ea lintho. Mohlala, optical fiber hydrophone ke mofuta oa sensor ea molumo e nkang fiber ea optical joalo ka ntho e hlokolosi, le sensor ea mocheso oa fiber ea optical.

• Sensor ea Surface Acoustic Wave

Sensor ea Surface Acoustic Wave (SAW) ke sensor e sebelisang sesebelisoa sa maqhubu a holimo e le ntho e utloang. Tlhahisoleseding e lekantsoeng e bonts'oa ke phetoho ea lebelo kapa khafetsa ea leqhubu la acoustic leqhubu ho sesebelisoa sa SURFACE acoustic wave, mme e fetoloa sensor ea motlakase e tsoang. Ke sensor e rarahaneng e nang le li-sensor tse ngata tse fapaneng. Haholo-holo e kenyelletsa sensor ea khatello ea maqhubu a maqhubu a holim'a metsi, sensor ea mocheso oa maqhubu a maqhubu a holim'a metsi, sensor e bohlale, joalo-joalo.

Ntle le passive optical fiber sensor e nang le kutlo e phahameng, e khona ho lekanya sebaka, litšoaneleho tsa tšebeliso e tlase ea matla, li-sensor tsa maqhubu a maqhubu li sebelisa Hui frequency fetola hakanya phetoho ea lebelo, kahoo phetoho ea cheke ho tekanyo e ka ntle e ka ba haholo. e nepahetseng, ka nako e ts'oanang e na le litšoaneleho tsa molumo o monyane, boima bo bobebe, tšebeliso e tlase ea matla e ka e lumella hore e fumane thepa e ntle ea mocheso le mochini, 'me e kenyelle nako e ncha ea li-sensor tse nyane tse se nang mohala. E sebelisoa haholo liteisheneng, tereneng, sebakeng sa lifofane le libakeng tse ling.

• Passive Sensor e Thehiloe ho Lisebelisoa tsa Matla

Li-sensor tsa Passive tse thehiloeng ho lisebelisoa tsa matla, joalo ka ha lebitso le bolela, li sebelisa matla a tloaelehileng bophelong ho fetola matla a motlakase, joalo ka matla a bobebe, matla a mocheso, matla a mochini joalo-joalo. Sensor ea passive e thehiloeng ho lisebelisoa tsa matla e na le melemo ea sehlopha se pharaletseng, bokhoni bo matla ba ho thibela ho kena-kenana le tšitiso, tšitiso e nyane ho ntho e lekantsoeng, kutlo e phahameng, 'me e sebelisoa haholo masimong a tekanyo ea motlakase joalo ka matla a phahameng a motlakase, lehalima, matla a masimo a mahlaseli a matla. matla a phahameng a microwave joalo-joalo.

Motsoako oa li-sensors tsa Passive le mahlale a mang

Lefapheng la Marang-rang a Lintho, li-sensor tse sa sebetseng li sebelisoa haholo le ho feta, 'me mefuta e fapaneng ea li-sensor tse sa sebetseng li phatlalalitsoe. Ka mohlala, li-sensor tse kopantsoeng le NFC, RFID esita le wifi, Bluetooth, UWB, 5G le lisebelisoa tse ling tse se nang mohala li hlahile. mohopolong o sa fetoheng, o bolokoang ha matla a sa fanoe.

Le li-sensor tsa masela tse se nang mohala tse thehiloeng ho theknoloji ea RFID, E kopanya theknoloji ea RFID le thepa ea masela ho theha lisebelisoa tse nang le ts'ebetso ea ho utloa khatello. RFID textile strain sensor e sebelisa mokhoa oa puisano le induction ea passive UHF RFID tag technology, e itšetlehile ka matla a motlakase ho sebetsa, e na le miniaturization le menyetla ea ho fetoha habonolo, 'me e fetoha khetho e ka bang teng ea lisebelisoa tse aparoang.

Qetellong

Passive Internet of Things ke tataiso ea nts'etsopele ea nakong e tlang ea Marang-rang a Lintho. Joalo ka sehokelo sa Marang-rang a Lintho, litlhoko tsa li-sensor ha li sa lekanyetsoa ho ts'ebeliso e nyane le e tlase ea matla. Passive Internet of Things le eona e tla ba tataiso ea nts'etsopele e lokelang ho ntlafatsoa. Ka kholo e tsoelang pele le boqapi ba theknoloji ea sensor ea passive, ts'ebeliso ea theknoloji ea sensor ea passive e tla ba kholo le ho feta.
