Kodi Passive Sensor ndi chiyani?

Passive sensor imatchedwanso mphamvu kutembenuka mphamvu. Monga intaneti ya Zinthu, sichifunikira mphamvu yakunja, ndiko kuti, ndi sensa yomwe sifunikira kugwiritsa ntchito magetsi akunja, komanso imatha kupeza mphamvu kudzera mu sensa yakunja.

Tonse tikudziwa kuti masensa amatha kugawidwa m'magulu okhudza kukhudza, zojambula zazithunzi, zowonetsera kutentha, zoyenda zoyenda, zowonetsera malo, magetsi a gasi, magetsi owunikira ndi magetsi othamanga malinga ndi kuchuluka kwa thupi la kuzindikira ndi kuzindikira. Kwa masensa osagwira ntchito, mphamvu zowunikira, ma radiation a electromagnetic, kutentha, mphamvu zosuntha za anthu ndi gwero la kugwedezeka komwe kumazindikiridwa ndi masensa ndi magwero amphamvu.

Zimamveka kuti masensa osagwira ntchito amatha kugawidwa m'magulu atatu otsatirawa: optical fiber passive sensor, surface acoustic wave passive sensor ndi passive sensor kutengera mphamvu zamagetsi.

• Optical fiber sensor

Optical fiber sensor ndi mtundu wa sensa yotengera mawonekedwe ena a fiber fiber yomwe idapangidwa mkati mwa 1970s. Ndi chipangizo chomwe chimasintha choyezera kukhala chizindikiro choyezera. Zili ndi gwero la kuwala, sensa, chowunikira chowunikira, chowongolera ma signal ndi kuwala kwa fiber.

Ili ndi mawonekedwe okhudzidwa kwambiri, kukana kwamphamvu kwamagetsi amagetsi, kutsekereza kwamagetsi kwamphamvu, kusinthasintha kwachilengedwe, kuyeza kwakutali, kugwiritsa ntchito mphamvu zochepa, ndipo ikukulirakulira pakugwiritsa ntchito intaneti yazinthu. Mwachitsanzo, cholumikizira CHIKWANGWANI hydrophone ndi mtundu wa kachipangizo phokoso amene amatenga CHIKWANGWANI kuwala ngati chinthu tcheru, ndi kuwala CHIKWANGWANI kutentha sensa.

• Surface Acoustic Wave Sensor

Sensor ya Surface Acoustic Wave (SAW) ndi sensor yomwe imagwiritsa ntchito chipangizo chapamwamba cha acoustic wave ngati chinthu chomvera. Chidziwitso choyezedwa chimawonetsedwa ndikusintha kwa liwiro kapena kuchuluka kwa mafunde amtundu wapamadzi mu chipangizo cha SURFACE acoustic wave, ndipo chimasinthidwa kukhala sensor yotulutsa magetsi. Ndi sensa yovuta yokhala ndi masensa osiyanasiyana. Zimaphatikizaponso sensor yamadzimadzi yamadzimadzi, sensor yamadzimadzi yamadzimadzi, sensor yamadzimadzi yamadzimadzi, sensor yanzeru, ndi zina zambiri.

Kupatula kungokhala chete kuwala CHIKWANGWANI kachipangizo ndi tilinazo mkulu, akhoza mtunda muyeso, makhalidwe otsika mphamvu mowa, kungokhala chete pamwamba lamayimbidwe masensa yoweyula ntchito Hui pafupipafupi kusintha ndikuganiza kusintha kwa liwiro, kotero kusintha cheke muyeso kunja kungakhale kwambiri. zolondola, nthawi yomweyo mawonekedwe a voliyumu yaying'ono, kulemera kopepuka, kugwiritsa ntchito mphamvu pang'ono kumatha kulola kuti ipeze zinthu zabwino zamatenthedwe komanso zamakina, ndikuyambitsa nthawi yatsopano ya masensa opanda zingwe, ang'onoang'ono. Amagwiritsidwa ntchito kwambiri mu substation, sitima, ndege ndi zina.

• Passive Sensor Yotengera Zida Zamagetsi

Masensa osasunthika otengera mphamvu zamagetsi, monga momwe dzinalo limatanthawuzira, amagwiritsa ntchito mphamvu wamba m'moyo kuti asinthe mphamvu zamagetsi, monga mphamvu yamagetsi, mphamvu ya kutentha, mphamvu yamakina ndi zina zotero. Kachipangizo kamene kamatengera mphamvu zamagetsi ali ndi ubwino wa bandi lalikulu, mphamvu zotsutsana ndi kusokoneza, kusokonezeka kochepa kwa chinthu choyezedwa, kukhudzidwa kwakukulu, ndipo amagwiritsidwa ntchito kwambiri m'magawo oyezera ma elekitiroma monga mkulu wamagetsi, mphezi, mphamvu yamphamvu yamagetsi, mkulu mphamvu microwave ndi zina zotero.

Kuphatikiza kwa Passive Sensors ndi Ma Technologies Ena

Pankhani ya intaneti ya Zinthu, masensa osagwira ntchito amagwiritsidwa ntchito mochulukira, ndipo mitundu yosiyanasiyana ya masensa omwe amangokhala asindikizidwa. Mwachitsanzo, masensa ophatikizidwa ndi NFC, RFID komanso ngakhale wifi, Bluetooth, UWB, 5G ndi maukadaulo ena opanda zingwe adabadwa. mu kukumbukira kosasunthika, komwe kumasungidwa pamene mphamvu sichinaperekedwe.

Ndipo ma sensa opanda zingwe opanda zingwe kutengera ukadaulo wa RFID, Amaphatikiza ukadaulo wa RFID ndi zida zansalu kupanga zida zokhala ndi vuto lozindikira. RFID textile strain sensor imagwiritsa ntchito njira yolumikizirana komanso induction yaukadaulo wa tag ya UHF RFID, imadalira mphamvu yamagetsi kuti igwire ntchito, imakhala ndi miniaturization komanso kusinthasintha, ndipo imakhala kusankha kwa zida zovala.

Kumapeto

Passive Internet of Things ndiye njira yakutsogolo yapaintaneti ya Zinthu. Monga ulalo wa zinthu zopanda pake pa intaneti, zofunikira zamasensa sizimangokhala zazing'ono komanso kugwiritsa ntchito mphamvu zochepa. Passive Internet of Things idzakhalanso njira yachitukuko yomwe ikuyenera kukulitsidwa. Ndi kukhwima kosalekeza komanso luso laukadaulo wa sensa ya passive, kugwiritsa ntchito ukadaulo wa passive sensor kudzakhala kokulirapo.
