RFID gaw Data hpe gara hku shinggyin tawn da nna shalai ya ai kun?

 

Lama na lama ma hpe RFID tag bang dat yang hti lu na re-warehouse inventory galaw yu ai ni kadai mung ndai lam ni kade daram shim lum ai hpe chye na ai. Raitim, convenience hpe tawn kau da nna, masha law malawng hpe data gara hku shang pru wa ai hpe teng sha tsun dan na matu tsun yang, shanhte n lu tsun dan ai. Ndai bungli de shawng nnan shang wa ai shaloi, ngai mung tsep kawp sum mat sai. Ngai n chye na shi yang, supplier ni kaw na kalang mi wan nat hkrum ra ai.

 

Tag kata na chip gaw grai kaji ai majaw myi hte n mu lu ai raitim, shingbyi shara nga ai. Chip model hta kade daram madung nga ai-manu n-htuk ai ni gaw 96-bit EPC sha nga ai, manu dan ai ni gaw kilobytes law law du hkra sa lu ai. 96 bits ni gaw kaji ai zawn na tim, teng sha nga yang ram sai. Hexadecimal de galai dat yang, 24 lang lu na re, dai gaw product code langai hpe shinggyin tawn na matu grau law ai. Client ni gaw, galaw shapraw ai shani, batch nambat, expiry date ni yawng hpe tag kata de cramming galaw na matu shadut ai hpe ngai mu yu sai. Math galaw ngut ai hpang, user memory kaba ai tags ni a manu gaw masum lang grau law ai. Shanhte gaw ID hpe sha shinggyin tawn da nna kaga yawng hpe database kaw bang da ai hku nna jahtum mat wa ai.

 

 

Nkau mi gaw, battery n lawm ai sha, tag ni gaw data ni hpe gara hku shinggyin tawn da ai ngu san ma ai. Dai shani hta mung dai zawn sha san yu sai. Turns out shanhte gaw EEPROM ngu ai power n lawm ai sha data ni hpe shinggyin tawn da ai storage medium hpe lang ai. USB flash memory hte n bung ai sha, EEPROM hpe byte langai hpang langai galai shai mai ai, flash gaw block ting hpe yeng seng kau ra ai. Dai gaw langai hkrai a record ni hpe ayan galai shai ai RFID a matu grau htap htuk ai. Dai hta ka da ai data gaw, dai tag hta grau nna shaning shi ning kaw nna hkun ning du hkra-grau galu kaba wa lu ai.

 

Data htawt sit ai tara gaw loi mi n-gun n rawng ai. Tag ni hta transmitter n nga ai hte signal ni hpe active hku n shabra ai. Laika hti ai wa gaw wan n-gun hpe shapraw ya nna, dai tag a antenna gaw dai hpe hkap la nna, induced current hpe shapraw ya ai, dai chip gaw dai n-gun kaji langai mi hta sha hkawm sa ai. Dai hpang, dai chip gaw langai mi galaw ai: antenna a load impedance hpe kalang lang galai shai kau ai. Impedance galai shai wa ai shaloi, nhtang pru wa ai wan n-gun a n-gun mung dai hte rau galai shai wa ai. Laika hti ai wa gaw ndai galai shai ai lam ni hpe reflected wave-tsa, npu, tsaw, npu-dai gaw na a 0s hte 1s ni hta mu lu ai.

 

 

Dai hpe backscatter ngu shamying ma ai. Client ni hpe tsun dan ai shaloi, dai term-too academic ngu ai hpe skip galaw chye ai. Ngai tsun ai gaw, dai tag gaw hkrang-galai shai ai shingran zawn re ai. Laika hti ai wa gaw, dai hpe flashlight hte htoi tu shangun nna, dai tag gaw, shingran a angle hpe galai shai nna, nhtoi hpe shi a nsen hte bai nhtang wa shangun ai. Hkum tsup ai hku n re tim, chye na loi ai.

 

Tengman ai bungli masing ni hta, bawnu kaba dik ai gaw theory-dai gaw grup yin hpe hkra machyi shangun ai lam n re. Metal gaw wan n-gun hpe nhtang shapraw ya nna, hka gaw dai hpe hkap la nna, sutdek ni hta dai lahkawng yan hpring nga ai. Lai wa sai shaning hta ngai gaw distillery langai mi kaw project langai mi galaw ai. Tag ni gaw glass gawm ni hta nga ai. Empty bottle ni gaw meter mali kaw nna manga du hkra hti lu ai shara jaw ai. Liquor hte hpring ai, dai gaw metre langai a npu de hkrat mat ai. Hpang jahtum e, tag tawn da ai shara hpe galai nna hparan lu saga ai. Metal gaw grau sawng ai. Kalang mi client langai mi gaw steel drum ni hta direct tags ni hpe bang da ai shaloi-dai hpe tsep kawp n mai hti ai. Anhte gaw anti-metal tags ni hpe lang nna, npu kaw wave-hkap la ai arung arai ni hpe lang nna jahtum kau ga ai. Cost gaw sanit, matsat lang rawt wa ai.

 

Frequency band ni mung ahkyak ai. Miwa mung na UHF gaw 920-925 MHz lang nna, USA gaw 902-928, Europe mungdan gaw 865-868 lang ai. Laika hti ai ni hpe mari ai shaloi, gara band ni hpe madi shadaw ai hpe yu u, n rai yang, maigan kaw na shapraw ai jak ni gaw mungdan kata kaw n mai lang ai. Ngai mu yu ai masha ni gaw gumhpraw hkoi shap na matu US kaw na lang sai reader ni hpe mari ai, frequency band shut ai hpe mu nna pyi n lu bai nhtang wa ai hpe mu ai.

 

 

Chip galaw ai ni gaw loi mi sha nga ai. Impinj a Monza series gaw, gat lawk hta grau law ai. NXP a UCODE mung law law nga ai. Chip n bung ai ni hta memory n bung ai hte hkam sha lam n bung ai. Sensitivity grau tsaw ai ngu ai gaw power kaji ai gaw tag hpe activate galaw ya lu ai, dai gaw read range grau galu ai ngu ai lachyum re. Lata ai shaloi, dai application hpe yu u-manu hpe sha n yu.

 

Ka ai cycle ni gaw loi loi hte n mu lu ai parameter langai mi re. EEPROM hpe 100,000 cycles a matu masat da ai, dai gaw law law zawn na ai, raitim nkau mi a mabyin masa ni gaw dai jahpan hpe teng sha hkra lu ai. Ngai gaw, shang wa ai hte pru wa ai shamu shamawt lam shagu hta, tag de langai mi ka ra ai ngu ai, bai nhtang wa mai ai container hparan ai bungli masing langai mi hpe galaw ai. Lani mi hta masum mali lang, shaning mi hta hkying mi jan lang nna, shi ning tup lang nna, teng sha max out galaw lu na re. Ngai gaw client switch hpe database hte paired galaw da ai tag ni hpe sha hti na matu hpaji jaw ai-tag gaw ID langai hpe sha shinggyin tawn da ai, kaga yawng gaw sumwi kata kaw update galaw ai. Manghkang hpe tsep kawp koi lu ai.

 

Security hpe hkum myit mada. Regular tag ni gaw EPC ginra hta password n ​​nga ai -kadai mung hti mai ai, ka mai ai. Access password hpe lock galaw na matu bang mai ai, raitim 32 bits sha re, shim lum ai lam n nga ai. Access control hte gumhpraw bang ai application ni hta, manu n bung ai chips ni hpe tsep kawp n bung ai hku lang ai. Logistics hta lang ai Tags ni gaw madung hku nna naked hku galaw nga ai-rai tim, shanhte gaw gara hku mi rai rai, classified data ni hpe n shinggyin tawn da ai. Shanhte hpe hti mai ai daram sha, dai gaw kaja ai.
