He aha ka Passive Sensor?

Kapa ʻia ka ʻike hoʻololi ʻana i ka ikehu. E like me ka Internet of Things, ʻaʻole pono ia i ka mana o waho, ʻo ia hoʻi, he sensor ʻaʻole pono e hoʻohana i ka mana o waho, akā hiki ke loaʻa i ka ikehu ma o ka sensor waho.

Ua ʻike mākou a pau e hiki ke hoʻokaʻawale ʻia nā mea ʻike i nā mea hoʻopā, nā kiʻi kiʻi, nā ʻike wela, nā neʻe ʻana, nā ʻike kūlana, nā ʻike kinoea, nā ʻike kukui a me nā ʻike kaomi e like me nā nui kino o ka ʻike a me ka ʻike. No nā mea ʻike passive, ʻo ka ikehu māmā, ka pāhawewe electromagnetic, ka mahana, ka ikaika o ka neʻe ʻana o ke kanaka a me ke kumu haʻalulu i ʻike ʻia e nā mea ʻike he mau kumu ikehu.

Hoʻomaopopo ʻia hiki ke hoʻokaʻawale ʻia nā mea ʻike passive i ʻekolu mau ʻāpana: optical fiber passive sensor, surface acoustic wave passive sensor a me passive sensor e pili ana i nā mea ikehu.

• ʻIkepili fiber Optical

ʻO ka ʻikena fiber Optical kahi ʻano ʻike e pili ana i kekahi mau hiʻohiʻona o ka fiber optical i hoʻomohala ʻia i ka waena o 1970s. He mea ia e hoʻololi i kahi kūlana i ana i kahi hōʻailona māmā hiki ke ana. Loaʻa iā ia ke kumu māmā, ka mea ʻike, ka mea ʻike kukui, ka kaapuni hōʻailona hōʻailona a me ka fiber optical.

Loaʻa iā ia nā hiʻohiʻona o ke kiʻekiʻe sensitivity, ikaika electromagnetic interference kū'ē, maikaʻi uila insulation, ikaika kaiapuni adaptation, mamao ana, haʻahaʻa mana hoʻohana, a me ka increasingly oo i ka noi o ka Internet o na mea. No ka laʻana, ʻo ka optical fiber hydrophone kahi ʻano kani kani e lawe i ka fiber optical ma ke ʻano he mea koʻikoʻi, a me ka ʻike wela o ka fiber optical.

• ʻIke ʻia o ka hawewe leo ʻili

ʻO Surface Acoustic Wave (SAW) sensor he mea ʻike e hoʻohana ana i kahi mea hawewe acoustic surface ma ke ʻano he mea ʻike. Hōʻike ʻia ka ʻike i ana ʻia e ka hoʻololi ʻana o ka wikiwiki a i ʻole ka alapine o ka nalu acoustic surface ma ka mea hawewe acoustic SURFACE, a ua hoʻololi ʻia i mea ʻike uila. He mea ʻike paʻakikī me ka laulā o nā mea ʻike. Loaʻa ia i ka mea maʻamau i ka ʻili o ka nalu acoustic hawewe ʻenekona, ka ʻili o ka hawewe wela o ka ʻili, ka ʻili o ka hawewe biological gene sensor, ka ʻenekona kinoea acoustic acoustic a me ka naʻauao, etc.

Ma waho aʻe o ka passive optical fiber sensor me ke kiʻekiʻe sensitivity, hiki ke ana i ka mamao, nā ʻano o ka hoʻohana haʻahaʻa haʻahaʻa, nā mea ʻike hawewe acoustic passive e hoʻohana i ka hui pinepine hoʻololi e kuhi i ka hoʻololi ʻana o ka wikiwiki, no laila hiki ke hoʻololi ʻia ka hoʻololi ʻana i ke ana i waho. pololei, i ka manawa like ia i nā hiʻohiʻona o ka leo liʻiliʻi, ke kaumaha māmā, ka hoʻohana haʻahaʻa haʻahaʻa hiki ke loaʻa iā ia ka maikaʻi thermal a me nā waiwai mechanical, A hoʻomaka i kahi au hou o ka uea, nā ʻike liʻiliʻi. Hoʻohana nui ia i ka substation, kaʻaahi, aerospace a me nā māla ʻē aʻe.

• ʻIke ʻia ka Passive ma muli o nā mea ikehu

ʻO nā meaʻike passive e pili ana i nā mea ikehu, e like me ka inoa, e hoʻohana i ka ikehu maʻamau i ke ola e hoʻololi i ka ikehu uila, e like me ka ikehu māmā, ka ikehu wela, ka ikehu mechanical a pēlā aku. Loaʻa i ka sensor passive e pili ana i nā mea ikehu nā mea maikaʻi o ka laulā ākea, ka ikaika anti-interference ikaika, ka liʻiliʻi o ka haunaele i ka mea i ana ʻia, ka ʻike kiʻekiʻe, a ua hoʻohana nui ʻia i nā kahua ana electromagnetic e like me ka uila kiʻekiʻe, ka uila, ka ikaika o ka pā radiation. kiʻekiʻe mana microwave a pela aku.

ʻO ka hui pū ʻana o nā ʻenehana Passive me nā ʻenehana ʻē aʻe

Ma ke kahua o ka Internet of Things, ua hoʻohana nui ʻia nā mea ʻike passive, a ua paʻi ʻia nā ʻano like ʻole o nā mea ʻike passive. No ka laʻana, ua hānau ʻia nā sensor i hui pū ʻia me NFC, RFID a me wifi, Bluetooth, UWB, 5G a me nā ʻenehana uila ʻē aʻe. i ka hoʻomanaʻo non-volatile, i mālama ʻia ke hāʻawi ʻole ʻia ka mana.

A me nā mea ʻike maka uila passive passive e pili ana i ka ʻenehana RFID, Hoʻohui ia i ka ʻenehana RFID me nā mea textile e hana i nā mea hana me ka hana strain sensing. Hoʻohana ʻo RFID textile strain sensor i ke kamaʻilio a me ke ʻano induction o passive UHF RFID tag ʻenehana, hilinaʻi i ka ikehu electromagnetic e hana, loaʻa ka miniaturization a me ka hiki ke hiki, a lilo i koho kūpono o nā mea hiki ke hoʻohana.

I ka hopena

ʻO ka Passive Internet of Things ka alakaʻi hoʻomohala e hiki mai ana o ka Pūnaewele o nā Mea. Ma ke ʻano he loulou o ka pūnaewele passive o nā mea, ʻaʻole i kaupalena ʻia nā koi no nā sensor i ka liʻiliʻi a me ka hoʻohana haʻahaʻa haʻahaʻa. ʻO ka Passive Internet of Things e lilo i alakaʻi hoʻomohala e pono ai ka mahiʻai. Me ka hoʻomau mau ʻana a me ka hana hou o ka ʻenehana sensor passive, e ʻoi aku ka nui o ka noi ʻana o ka ʻenehana sensor passive.
