Engtin Nge RFID hian Data A Store Leh Transmit?

 

Thil pakhatah RFID tag slap la, i chhiar thei ang-warehouse inventory ti tawh tu pawhin heng thilte hi a awlsam zia an hria. Mahse convenience aside, mi tam zawk hnenah data a luh leh chhuah dan dik tak sawifiah turin i ti a nih chuan an ti thei lo. He industry ka luh tirh khan kei pawh ka bo vek tawh. Thil ka ngaihtuah chhuah hmain supplier-te’n vawi engemaw zat an hal a ngai a ni.

 

Tag chhunga chip hi a te em em a, mit chauh pawhin i hmu thei lo a, mahse storage space a nei tho. Engzat nge chip model-ah a innghat-a man tlawm zawkte chuan 96-bit EPC chauh an nei a, a man to zawkte chu kilobyte engemaw zat thleng a kal thei. 96 bits a tlem a, mahse a takah chuan a tawk. Hexadecimal ah convert la, character 24 i hmu ang a, product code dahna tur aia tam a ni. Client-te chuan production date, batch number, leh expiry date zawng zawng tag-ah cramming vek an tum tlat tih ka hmu tawh. Math kan tih zawh chuan user memory lian tak nei tag te chu a let thum zetin a man a to zawk. ID chu dahkhawmin thil dang zawng zawng chu database-ah dah mai maiin an tawp ta a ni.

 

 

Mi thenkhat chuan tag hian battery tel lovin engtin nge data a dahkhawm tih an zawt thin. Zawhna ang chiah kha ka zawt leh a. Turns out EEPROM an hmang a, chu chu storage medium a ni a, power tel lovin data a vawng reng a ni. USB flash memory ang lo takin EEPROM hi byte khat hnu byte khatin a siam danglam thei a, flash hian block pum pui a erase a ngai thung. Chu chu mimal record i thlak fo thinna RFID atan a tha zawk. A hnena data ziah chu tag ngei aiin kum sawm atanga kum sawmhnih-a rei thei.

 

Data transmission principle hi a buaithlak deuh a ni. Tag hian transmitter an nei lo va, active takin signal an thawn lo. Reader hian electromagnetic wave a pe chhuak a, tag antenna chuan a la a, induced current a siam a, chu power tlemte hmangin chip chu a kal a ni. Tichuan chip hian thil pakhat a ti a, chu chu antenna load impedance chu a thlak nawn leh thin. Impedance a inthlak chuan reflected electromagnetic wave chakna pawh a inthlak ve ve bawk. Reader chuan heng danglamna te hi reflected wave-high, low, high, low-chu chu i 0s leh 1s a ni tih a hmuchhuak a ni.

 

 

Hei hi backscatter an ti a. Client te hnena ka hrilhfiah hian chu term chu ka skip tlangpui-too academic. Tag hi shape-shifting mirror ang mai a ni ka ti mai. Chhiartute chuan flashlight hmangin a rawn eng a, tag chuan mirror angle thlak danglamin a rhythm-ah light chu a rawn reflect leh ta a ni. A dik famkim lo, mahse hriatthiam awlsam tak a ni.

 

Project tak takah chuan lu na ber chu theory-environment interference a ni lo. Metal hian electromagnetic wave a reflect a, tuiin a hip lut a, warehouse-ah pawh a pahnih hian a khat vek a ni. Nikum khan distillery pakhatah project ka ti a. Tags chu glass bottle-ah a awm a. Bottle hrui hring chuan meter li atanga metre nga inkar read range a pe a ni. Zuin a khat a, chu chu meter khat hnuai lamah a tlahniam ta a ni. A tawpah chuan tag placement kan thlak danglam ta a ni. Metal pawh a chhe zawk. Vawikhat chu client pakhatin steel drum-a tag direct-a a stuck- chuan a chhiar thei lo tak zet a ni. Kan tawp dan chuan anti-metal tags hmangin a hnuaiah wave-absorbing material layer a awm a. Cost chu vawi sarih emaw vawi riat emaw a sang a ni.

 

Frequency band pawh a pawimawh hle. China UHF hian 920-925 MHz a hmang a, US hian 902-928 a hmang a, Europe hian 865-868 a hmang bawk. Reader i lei dawnin eng band nge an support tih enfiah la, chutiang a nih loh chuan imported equipment te chu ram chhungah a thawk thei lo mai thei. US atanga sum khawlkhawm nan miten reader hman tawh an lei ka hmu a, chutah chuan frequency band a dik lo tih an hmuchhuak a, an rawn pe let thei lo pawh a ni.

 

 

Chip siamtu tlemte chauh an awm. Impinj-a Monza series hian market share a nei sang ber a ni. NXP-in UCODE an tih pawh a awm fo. Chip hrang hrang hian memory configuration leh sensitivity hrang hrang an nei a. Sensitivity sang zawk hian power tlem zawkin tag a activate thei tihna a ni a, hei hian read range rei zawk tihna a ni. Selection i tih hian application bik kha en la-a man chauh en suh.

 

Write cycle hi awlsam taka ngaihthah theih parameter a ni. EEPROM hi cycle 100,000 rated a ni a, hei hi a tam hle niin a lang a, mahse scenario thenkhat chuan chu number chu a hit tak tak thei a ni. Returnable container management project ka thawk a, inbound leh outbound movement tin hian tag-ah ziak pakhat a awm tihna a ni. Ni khatah cycle thum emaw pali emaw, kum khatah sangkhat aia tam, kum sawm chhung hmang la, a takin i max out thei. Client switch chu -database nena paired tag chauh chhiar turin ka rawt a-tag hian ID a dah mai a, thil dang zawng zawng chu cloud-ah update vek a ni. Buaina chu pumpelh vek a ni.

 

Security ah hian ring suh. Regular tag hian EPC area-ah password a nei lo by default-tu pawhin an chhiar thei a, an ziak thei bawk. Lock down turin access password i set thei a, mahse bit 32 chauh a ni a, a secure harsa hle. Access control leh payment application-ah hian chip class danglam tak, price point danglam tak hmanga siam a ni. Logistics-a tag hman thin te hi a bul berah chuan saruakin an kal thin-mahse, hetah pawh hian, engtin pawhin classified data an dahkhawm lo. Chhiar theih an nih chhung chuan chu chu a tha tawk.
