Telecom Dumb Zviwanikwa uye RFID: Zvatinoudzwa neNhamba

 

Mubvunzo Wekukura Kwemusika

 

Iyo AIoT Star Mepu Research Institute's 2025 chena bepa inoda 500 bhiriyoni mbeveve zviwanikwa munyika yose, ichiturikira ku50-100 bhiriyoni tags pagore. Nhamba iyoyo inoda mamiriro. Mapurovhinzi akasiyana anoverengera zvakasiyana - Jiangsu inoverengera imwe fiber musimboti, ukuwo Zhejiang achiverenga nemajunction box masumbu. Kubva pamavhoriyamu chaiwo manyoro atinoteedzera, 200-300 bhiriyoni iri padyo nezvokwadi, asi kunyangwe izvo zvinotora kutumirwa kuzere.

 

Hezvino zviri kuitika chaizvo: Jiangsu, Zhejiang, Xinjiang, uye Yunnan vari kutyaira-mamiriyoni evatyairi vezvikepe. Mamwe mapurojekiti asvika 5-8 miriyoni mayunitsi. Indasitiri-yakapararira gore rapfuura yaive pakati pe30-40 miriyoni renji - kwete mazana emamiriyoni emamwe mafambiro aitaurwa. Kupinda kwazvino kuri pasi pe1%. Iyo 10% panosvika 2029 fungidziro haitore makuru ehunyanzvi migwagwa, izvo zvisati zvave chiitiko chedu.

 

 

Nei Passive RFID (uye Nei Yakaoma)

 

Battery-kushanda kwemahara kunonzwika kune zvivakwa zvakapararira zviuru zvemaskweya kilometa. Matagi anoshanda 10+ makore pasina gadziriso - muchiono. Xinjiang yechando field bvunzo inotaura nyaya yakasiyana. Tatsvaga kukundikana kuri kuita 20-30% pagore rechitatu apo ma tag anotarisana -35℃kusvika +65 madhigirii zuva nezuva. Iyo ceramic antenna dhizaini inobatsira, asi wedzera mutengo.

 

Dambudziko resimbi riri pamusoro nderechokwadi. Standard UHF ma tag anowana pamwe 1 mita yekuverenga chinhambwe pane simbi manhole mavhavha kana aluminium junction mabhokisi. Anti-matagi esimbi anoshandisa zvinonyudza anogona kusundidzira kuti kusvika ku3-5 metres, asi uri kutarisa ¥2.5-4 payuniti maringe ne¥0.8 yematagi akajairwa. Vashandi vanoda kushanda pamitengo yakajairwa - iro gap harisati ravhara.

 

Kubatanidzwa kweSystem ndiko uko vatyairi vanomira kunze. Mapuratifomu eGIS kubva kuma2010 haana kuvakirwa RFID data zvimiro. Isu takaona mapurojekiti achipedza mwedzi misere angori padhatabhesi schema alignment isati yatumira imwe tag. Iyo "6-12 mwedzi yekumisikidza nguva" kazhinji inoreva 4 mwedzi yekumisikidzwa kwemaki uye 8-14 mwedzi yekumashure wrestling.

 

5G-Maserura eIoT mwero (R19/R20) anogona kushandura miganhu, asi izvo zvakatemwa zvichiri kupedzwa. Vamwe vatengesi vari kubheja pairi, vamwe havana kumirira.

 

Chii Chinononoka Izvi

Kwatinokwana Mune Izvi

 

 

Isu tinogadzira ma tag eUHF RFID - angangoita mamirioni makumi maviri pamwedzi pamaapplication ese. Telecom zvivakwa zvinomiririra zvimwe 10-15% yevhoriyamu yedu, yakanangidzirwa muQ2-Q3 kana vashandisi vachimhanyisa kutenderera kwavo.

 

Pamusoro pe-metal tag mubvunzo:Yedu yakakosha maRFID tag anoshandisa ceramic antenna substrates ine ferrite absorber inotsigirwa. Izvi zvinoita kuti uverenge 4-5 metres pasimbi nealuminium. Vamwe vakwikwidzi vanoshandisa furo-madhizaini anoedza zvakanaka mumamiriro emurabhoritari asi isu takaona nyaya dzekupinda kwemvura mukutumirwa chaiko mushure memwedzi 18-24. Iyo IP67 chiyero chine basa, asi ndozvinoita kwenguva refu chisimbiso kutendeseka kana ma tag achipfuura nechando-thaw mitsetse.

 

Kusarudzwa kwechip kuri kuwana kunakidza.Alien H3 neImpinj M730 zvichiri kutonga nyaya dzenharembozha, asi machipisi emuChinese emumba arikuonekwa mune-maapplications akakosha uko musiyano we1-2dB wekunzwa uchigamuchirwa uye 30-40% yekudzikisa mutengo ichinyanya kukosha. Tiri kuedza zvose. Mubvunzo wekutengesa mudzimba hausi wemutengo chete - uri nezve porisi yekutenga uye kuwanikwa kwenguva refu.

 

Yedu UHF RFID tag yekugadzira inoshandisa ultrasonic chisimbiso pane inonamira chisungo chechiyero chezvakatipoteredza. Izvo zvinowedzera mutengo wemidziyo asi zvinoderedza mwero wekutadza watinoona mumasampuli akadzoserwa kubva pazasi 0.5% kusvika kunosvika 0.2-0.3%. Kune miriyoni-tag kutumirwa, iwo musiyano unokosha.

 

Vaverengi vanobata ruoko ndipo panowanikwa kuomarara kwekubatanidza. Vashandi vanoda vaverengi vanobatana kune yavo iripo mobile workforce apps, kwete midziyo yakamira. Bluetooth yekubatanidza ndiyo yakajairwa izvozvi, asi kuenderana kweAPI neakasiyana maodha masisitimu ese itsika yekubatanidza basa.

 

Zvatiri kutevera:Mapurojekiti anomira pane chaiwo tag anoumba zvinhu uye nzira dzekukwira usati wahodha. Iwo anohodha ma tag anobva aona kuisirwa kazhinji ane 10-15% marara kubva pakukwira kusiri iko kana kukuvadzwa panguva yekuendesa. Kuwanikwa kwemidziyo yevaverengi kwakaomarara - nguva dzekutungamira dzakatambanudzwa kusvika kumavhiki masere-12 gore rapfuura apo mapurovhinzi akawanda akakwira panguva imwe chete.

 

The Reality Check

 

Musika uyu unokura mumatanho, kwete macurves. Zviziviso zvevatyairi hazviwanzo kushandura kuodha yevhoriyamu. Madimikira ehunyanzvi anogadziridzwa pakati-nechirongwa. Mamwe matunhu acharova 20% kupinda nepo mamwe achigara pa2%.

 

Isu tinochengeta huwandu hwekugadzira huchichinjika uye tinochengeta heta yeakajairwa tag mafomati pane kubheja pane zvinoputika zvinodiwa. Yedukugadzirwa kwekugadzirainobata ese madiki madiki evatyairi (50K-200K) uye makuru epurovhinzi deployments (5M+) ane maitiro akafanana emhando.

 

Kune vashandisi vanoongorora RFID deployments: iyo tag mutengo chikamu chiri nyore. Kuisa basa, zvishandiso zvevaverengi, backend kubatanidzwa, uye inoenderera mberi data management inowanzomhanya 3-5x mutengo weti. Vatengesi vanongotora mitengo yemateki havasi kukupa mufananidzo uzere.

 

Mukana wezviwanikwa zvenharembozha ndewechokwadi, asi ibhizimusi rezvivakwa - marefu marefu, vanobata mabasa akaomarara, kunyatsosimbisa. Zvinoenderana nematauriro atinoita.
