Telecom Dumb Resources ndi RFID: Zomwe Manambala Amatiuza Kwenikweni

 

Funso Lakukula Kwa Msika

 

Mapepala oyera a AIoT Star Map Research Institute a 2025 amati pali zinthu zosalankhula mabiliyoni 500 m'dziko lonselo, kumasulira ma tag 50-100 biliyoni pachaka. Nambala imeneyo imafunikira nkhani. Zigawo zosiyanasiyana zimawerengera mosiyana - Jiangsu amawerengera nsonga iliyonse ya fiber, pomwe Zhejiang amawerengera ndi magulu ophatikizira mabokosi. Kutengera ndi ma voliyumu enieni omwe timatsata, 200-300 biliyoni ili pafupi ndi zenizeni, koma ngakhale izi zimatengera kutumizidwa kwathunthu.

 

Izi ndi zomwe zikuchitika: Jiangsu, Zhejiang, Xinjiang, ndi Yunnan akuyendetsa-oyendetsa ma tag mamiliyoni ambiri. Ntchito zina zidagunda mayunitsi 5-8 miliyoni. Mafakitale-kutumizidwa kochuluka chaka chatha kunali pakati pa 30-40 miliyoni - osati mazana a mamiliyoni omwe ena amanenedweratu. Kulowa kwapano kuli pansi pa 1%. Chiyembekezo cha 10% pofika 2029 sichikhala ndi zopinga zazikulu zaukadaulo, zomwe sizinachitikepo.

 

 

Chifukwa chiyani Passive RFID (ndi Chifukwa Chake Ndi Yovuta)

 

Battery{{0}ntchito yaulere ya batri imakhala yabwino kwambiri pamapangidwe amwazikana masauzande ma kilomita. Ma tag amagwira ntchito zaka 10+ osakonza - m'malingaliro. Mayesero akumunda a Xinjiang amafotokoza nkhani yosiyana. Tatsata ziwopsezo zakulephera kufika pa 20-30% pofika chaka chachitatu pamene ma tag amayang'anizana ndi -35 digiri kufika ku +65 kusinthasintha kwatsiku ndi tsiku. Mapangidwe a mlongoti wa ceramic amathandiza, koma onjezani mtengo.

 

Vuto lachitsulo pamwamba ndi lenileni. Ma tag okhazikika a UHF amapeza mtunda wowerengeka wa mita imodzi pazivundikiro zazitsulo zazitsulo kapena mabokosi ophatikizika a aluminiyamu. Anti-ma tag achitsulo pogwiritsa ntchito zinthu zothira amatha kukankhira mpaka 3-5 metres, koma mukuyang'ana ¥2.5-4 pa unit motsutsana ndi ¥0.8 pama tag okhazikika. Othandizira akufuna magwiridwe antchito pamitengo yokhazikika - kusiyana kumeneku sikunatsekebe.

 

Kuphatikizana kwadongosolo ndi komwe oyendetsa ndege amasiya. Mapulatifomu a GIS kuyambira m'ma 2010 sanamangire ma data a RFID. Tawona mapulojekiti amatha miyezi 8 akungolumikizana ndi schema ya database tisanatumize chizindikiro chimodzi. "Miyezi 6-12 yokhazikitsa nthawi" nthawi zambiri imatanthawuza miyezi inayi yotumizira ma tag ndi miyezi 8-14 yakulimbana ndi backend.

 

5G-Miyezo ya ma IoT a m'manja (R19/R20) ikhoza kusintha malire, koma mfundozo zikumalizidwabe. Mavenda ena akubetcha pa izo, ena sakudikirira.

 

Zomwe Zimachepetsa Izi

Kumene Timakwanira Izi

 

 

Timapanga ma tag a UHF RFID - pafupifupi mayunitsi 20 miliyoni pamwezi pamapulogalamu onse. Zomangamanga za telecom zimayimira mwina 10-15% ya voliyumu yathu, yokhazikika mu Q2-Q3 pomwe ogwira ntchito amayendetsa maulendo awo otumizira.

 

Pa funso la anti-metal tag:Ma tag athu apadera a RFID amagwiritsa ntchito magawo a tinyanga ta ceramic okhala ndi chothandizira cha ferrite. Izi zimakuthandizani kuti muwerenge 4-5 mita pazitsulo ndi aluminiyamu. Ena opikisana nawo amagwiritsa ntchito thovu-kutengera mapangidwe omwe amayesa bwino m'ma laboratories koma tawona zovuta za madzi pakutumizidwa pambuyo pa miyezi 18-24. Mulingo wa IP67 ndi wofunika, komanso kukhulupirika kwanthawi yayitali pamene ma tag amadutsa munyengo yachisanu.

 

Kusankhidwa kwa chip kumakhala kosangalatsa.Alien H3 ndi Impinj M730 akadali akadali akadali pazambiri zapa telecom, koma ma chips aku China akunyumba akuwoneka mu-mapulogalamu osafunikira kwambiri momwe kusiyana kwa 1-2dB ndikovomerezeka komanso 30-40% kuchepetsa mtengo ndikofunikira kwambiri. Tikuyesa zonse ziwiri. Funso lokhudzana ndi zogulira zapakhomo silimangokhudza mtengo - likukhudza mfundo zogulira zinthu komanso kupezeka kwanthawi yayitali.

 

Kupanga kwathu ma tag a UHF RFID kumagwiritsa ntchito kusindikiza kwa ultrasonic m'malo momangirira zomatira pazowunikira zachilengedwe. Izi zimawonjezera mtengo wa zida koma zimachepetsa kuchuluka kwa kulephera komwe timawona mu zitsanzo zomwe zabwezedwa kuchokera pansi pa 0.5% kufika pafupifupi 0.2-0.3%. Pakutumizidwa kwa ma miliyoni miliyoni, kusiyana kumeneku ndikofunikira.

 

Zowerenga zam'manja ndizomwe zimawonekera zovuta kuphatikiza. Ogwiritsa ntchito amafuna owerenga omwe amalumikizana ndi mapulogalamu omwe alipo, osati zida zodziyimira zokha. Kulumikizana kwa Bluetooth ndikokhazikika tsopano, koma kuyanjana kwa API ndi machitidwe osiyanasiyana ogwirira ntchito ndi ntchito yophatikizira.

 

Zomwe tikutsata:Ma projekiti omwe amakhazikika pama tag enieni amapangira zinthu ndi njira zoyikira musanayitanitsa. Omwe amayitanitsa ma tag kenako amazindikira kuyika nthawi zambiri amakhala ndi zinyalala 10-15% kuchokera pakukweza kapena kuwonongeka kolakwika panthawi yotumiza. Kupezeka kwa zida zowerengera ndizovuta - nthawi zotsogola zidafikira masabata 8-12 chaka chatha pomwe zigawo zingapo zidakwera nthawi imodzi.

 

The Reality Check

 

Msika uwu umakula pang'onopang'ono, osati ma curve. Zolengeza za oyendetsa ndege sizimasuliridwa nthawi zonse kukhala ma voliyumu. Zaukadaulo zimawunikiridwa pakati-pantchito. Madera ena adzagunda 20% kulowa pomwe ena amakhala pa 2%.

 

Timasunga mphamvu zopangira kukhala zosinthika ndikusunga zolemba zama tag wamba m'malo mobetcha pongofuna kuphulika. Zathukupanga kupangaimagwira magulu ang'onoang'ono oyendetsa ndege (50K-200K) ndi magulu akuluakulu a zigawo (5M+) omwe ali ndi machitidwe ofanana.

 

Kwa ogwira ntchito omwe akuwunika kutumizidwa kwa RFID: mtengo wama tag ndi gawo losavuta. Ntchito yoyika, zida zowerengera, kuphatikizira kumbuyo, ndi kasamalidwe ka data kosalekeza nthawi zambiri zimayendera 3-5x mtengo wa tag. Ogulitsa omwe amangotchula mitengo yama tag sakukupatsani chithunzi chonse.

 

Mwayi wazinthu zosayankhula za telecom ndi wowona, koma bizinesi ya zomangamanga - nthawi yayitali, okhudzidwa kwambiri, kutsimikizira mosamalitsa. Izi zimagwirizana ndi momwe timachitira.
