Kongera ibikorwa hamwe na LF ndende Urutonde Tagi Uyu munsi
Apr 13, 2026
Tanga ubutumwa
Birashoboka ko wabwiwe ko niba porogaramu yawe ikeneye gusoma birenze santimetero 10, ugomba guhindura UHF. Izi nama zifata hafi 70% yigihe - ariko izindi 30% zirimo ibidukikije aho UHF idakora gusa: kashe ya kashe ikikijwe nibikoresho byuma, amarembo yubworozi hamwe ninyamaswa zitose zinyura, cyangwa sisitemu yo kugera kumurage aho gusenya ibikorwa remezo 125 kHz bidakwiye ikiguzi.
Iki gice ni icya 30%. Tuzanyura mubyukuri byagura gusoma intera kuri frequency nkeya, aho physics itera imipaka igoye, namakosa yo kohereza twabonye ingengo yimishinga yumushinga udakemuye ikibazo cyibanze. Niba spake yawe ihamagarira cm 60 kugeza kuri metero 1 isoma mubyuma - biremereye cyangwa amazi - ibidukikije bigaragara, ibisobanuro bikurikira biremeza ko LF arinzira yawe cyangwa ikagukiza guta amezi atatu ugerageza gukora aho itazajya.
Fizika mu nteruro imwe - n'impamvu itavuga inkuru yose
Umuvuduko muto - RFID ihererekanya ingufu binyuze mu guhuza inductive aho kuba imirasire ya electromagnetique, niyo mpamvu tagi ya pasiporo isanzwe hejuru ya cm 10. Ariko ibyo nibyo shingiro, ntabwo ari igisenge.
Igisenge giterwa nimpinduka eshatu zikorana muburyo urupapuro rwerekana rutazakwereka: umusomyi wa antenna ya diametre, agace ka coil agace, hamwe na Q ibintu byumuzunguruko. Itsinda ryacu ryubwubatsi ryakoze igereranya umwaka ushize dukoresheje kimweEM4200 chiphejuru yubunini butatu. Igiceri cya mm 45 kizunguruka cyageze kuri cm 24 kurwego rwintebe yacu; gupima kugeza kuri mm 97 y'urukiramende rusunika kuri cm 41; ariko kongera gukuba kabiri kuri 200 mm form form yongeyeho cm 18 gusa. Kugabanuka kugaruka gushizwemo mugihe coil yegereye umusomyi antenne hafi yumupaka wumurima -.
Abasomyi kabuhariwe 125 kHz bagenewe kugera kubinyabiziga - nka seriveri ya Promag GP90 - basaba cm 90 hamwe namakarita ya ISO na cm 130 hamwe nubuniniibyangombwa bya clamshellmunsi ya 18-19V imbaraga. Sisitemu yo kumenya inyamaswa kuri 134.2 kHz ikurikiraISO 11784/11785 Inyandiko zasomwe zirenze metero 2 mubidukikije bigenzurwa, nubwo ibyo gushiraho bikoreshaantennebyinjijwe mumarembo adashobora guhuza ibirenge byinshi byinganda.
Niba LF ishobora kugera kure ntabwo arikibazo - irashobora. Niba antenne geometrie na tagi yibintu bikugezaho bizahuza gahunda yawe niho imishinga myinshi igenda nabi mbere yuko itangira.
Inzira eshatu za tekiniki - hamwe nUrwego rwo gufata ibyemezo rukora
Niba ukeneye tagi ya LF isoma kuri cm 50 cyangwa irenga, uhitamo hagati yuburyo butatu. Dore uko tuyobora abakiriya binyuze muri kiriya cyemezo.
Kurenza umusomyi antenne ikomeza kuba ifarashi yakazi kubikorwa byinshi bya LF ndende ndende yoherejwe.
Umurambararo wa mm 300-500 mm utanga imirima ikomeye igera kure. Twabohereje kugirango tumenye ibinyabiziga mu kigo gikwirakwiza muri Guadalajara - hasi - imirongo yashyizwe munsi ya kaburimbo, GP90 - abasomyi bahuje, ibimenyetso bisanzwe bya clamshell ku kirahure. Soma intera: cm 95 zizewe, cm 110 mubihe byiza. Gufata: ikirenge cya antenne gake gihuye nuburyo busanzwe - kugenzura, kandi ukeneye Q agaciro kari hejuru ya 100 kugirango wirinde guta ingufu nkubushyuhe. Iyi nzira ikora iyo ugenzuye ibikorwa remezo kandi ushobora kubaka hafi yubunini bwa antene. Igiciro kuri tagi kiguma mumadorari $ 0.35–0.80 bitewe nimpamvu zifatika; ikiguzi nyacyo ni ugushiraho abasomyi.
Semi - tagifungura ibiciro.
Ibi byashizemo bateri kugirango yongere imbaraga za chip ariko iracyashingira kumurima wabasomyi kugirango basubire inyuma. Igeragezwa ryimbere ryerekana kwaguka 35-45% kwaguka ugereranije na passiyo ihwanye numusomyi umwe - ariko kuri - igiciro cyasimbutse kigera kuri $ 1.50–3.50 bitewe nurutonde rwikigo. Ubuzima bwa Batteri bukoresha imyaka 5-7 mugihe cyinshingano zisanzwe (imwe isomwa kumunota, amasaha 8 / kumunsi), ariko igabanuka vuba mububiko bukonje cyangwa hejuru -.
Dore amategeko yicyemezo dukoresha imbere, dushingiye ku kwerekana ibiciro mu mishinga igera kuri 40 kuva 2021:niba ikoreshwa rya tagi yawe ya buri kwezi iri munsi ya 300 kandi usome intera ikenewe iri munsi ya cm 80, antenne nini cyane hafi gutsindira kubiciro byose. Hejuru ya 300 / ukwezi hamwe nibisomwa birenze metero 1, koresha umwaka wa - TCO igereranya hagati ya - tagi ya pasiporo hanyuma wongereho amanota menshi yo gusoma hamwe na tagi.Iyo mibare ihindagurika bitewe nigiciro cyakazi cyawe cyo gushiraho abasomyi.
Amatara ya LF akora arahari ariko gake yumvikana kubikorwa byo kumenyekanisha.
Batteri - ikoresha amashanyarazi itangiza itumanaho irashobora kurenga metero 10, ariko icyo gihe ntabwo rwose ukora "LF RFID" muburyo gakondo - inyinshi muri sisitemu zikoresha LF wake - hejuru ibimenyetso bifatanije numuyoboro mwinshi wa -. Twasubiyemo aya magambo yo gucukura ibinyabiziga bikurikirana aho UHF idashobora kwinjira mu bucukuzi bw'amabuye y'agaciro, ariko kubiranga inganda zisanzwe, kubungabunga ibidukikije byica urubanza rwubucuruzi.
Niba urimo gusuzuma LF yaguye - urutonde rwibikoresho byinshi, urupapuro rwibicuruzwa ntirukubwira inzira ihuye nurubuga rwawe. Ibidukikije bizabikora.
Iyo LF Irenze UHF - hamwe na Scenario imwe aho idakora
Mubidukikije byuzuyemo ibyuma cyangwa amazi, LF yaguye - imiterere iranga ikomeza gusoma kwizerwa UHF irwanira guhuza. Fizika: Ibimenyetso bya UHF kuri 860 - 960 MHz byerekana hejuru yimyitwarire kandi byinjira mumazi - ibikoresho bikungahaye; Imirasire ya LF inyura hamwe na bike cyane.
Twashyizeho ibirango bya LF kumurongo wo muri Amerika ya ruguru - 1 utanga amamodoka akurikirana imbaho zisize irangi binyuze mumashanyarazi akiza, icyuma muri primer idakize, ikibazo cyose. Igipimo cyo gusoma nabi: 0.08%. Uwahoze atwara UHF ntashobora kubona munsi ya 4% kubera gutekereza. Kuri iyo porogaramu, LF niyo yonyine yahisemo.
Ikintu kimwe kidasanzwe gikwiye kwitonderwa: imiterere - imiterere UHF kuri - ibimenyetso byicyuma byateye imbere cyane. Niba ibyuma byawe bisa neza, birasa, kandi urashobora kwemeza icyerekezo cyerekanwe, ibicuruzwa nka seriveri ya Xerafy PICO cyangwa Confidex Ironside noneho wegera LF kwizerwa mugihe utanga metero 3-5. Twabonye iki gikorwa muri pallet ikurikirana aho tagi ihagarara kumwanya umwe buri gihe. Ntabwo ikora mugihe tags yimuka bitateganijwe ugereranije numusomyi - isobanura amatungo menshi hamwe ninteko nyinshi - umurongo.
Isuzuma rinyangamugayo: LF yaguye - soma ibisubizo bifata umurongo wihariye - 0.5 kugeza kuri metero 2, ibidukikije bya RF byanga, porogaramu aho kuri - tag igiciro cyibiciro biri munsi yikiguzi cyibikorwa remezo byabasomyi. Hanze y'iryo tsinda, UHF ubusanzwe iratsinda. Imbere, UHF mubisanzwe birananirana. Menya itsinda umushinga wawe ugwamo mbere yuko ugaragaza ikintu icyo aricyo cyose.
Kunanirwa Kwohereza Ko Twakemuye Mubyukuri
Ikosa rihenze cyane muri LF ndende - intera ya RFID ntabwo igura ibyuma bitari byo - irimo gushiraho ibyuma bikwiye. Hano hari uburyo butatu bwo kunanirwa twahamagariwe gukosora.
Phantom isoma kubasomyi bafite imbaraga zishe umushinga wa Monterrey logistique mbere yuko tubigiramo uruhare.Integrated yamaze ibyumweru bitatu ikemura ibibazo byabazimu. Umusomyi yashyizwe kumurongo ntarengwa wemewe, yongerera umurima kurenga ahabigenewe gusoma no gutora tagi mumihanda yegeranye. Gukosora kwacu byatwaye amasaha abiri: ingufu kugeza kuri 60% (hafi 18 dBm), ongeramo panneur ya RF yinjira kumupaka wa zone. Kurwanya ibintu, ariko imbaraga zo hasi zitanga amakuru asukuye.
Laboratoire - urwego rwemewe ntirurokoka guhura nibyuma.Umusomyi yashyizwe kuri cm 30 uvuye kumurongo wicyuma arashobora gutakaza kimwe cya kabiri cyurugero rwiza bitewe numuyaga uterwa uhagarika umurima wa geometrie. Ubu dukeneye pre - ubushakashatsi bwimbuga zoherejwe hamwe nisesengura rya sprifike kumushinga uwo ariwo wose urimo ibyuma. Ntabwo ari ubushake - ni itandukaniro riri hagati ya sisitemu ikora kumunsi wa mbere nimwe ikenera ibyiciro bibiri byo kwimura nyuma yo kujya - live.
Raw isoma imiyoboro mu buryo butaziguyeWMSgusenya amakuru neza.Hatabayeho gushungura hagati - gukuraho inshuro ebyiri, gutura - igihe ntarengwa, akarere - gushingira kugabanywa - ubunyangamugayo akenshi bugwa munsi ya 75%. Muri bitatu LF - kugeza - Kwinjiza WMS twagenzuye mu myaka ibiri ishize, ibyingenzi mbere yo kuyungurura byari kuva kuri 68% kugeza kuri 79%. Ibyuma byakoraga neza; kwinjiza software ntabwo.
Niba ushakisha ibirango birebire bya LF kubitanga bishya, baza uburyo bakemura ibi bintu. Utanga ibicuruzwa gusa agurisha tagi akakwereka ahandi kugirango abasomyi bahuze cyangwa inkunga yo kwishyira hamwe araguha ibice nta mabwiriza yinteko.
Guhitamo Ibyuma Utarinze kwishyura
Kumasoko menshi ya 125 kHz yongerewe - soma ibirango, urupapuro rwerekana ibintu bitarenze imiterere yoherejwe. Ikirangantego gipima cm 80 kumurongo wintebe kirashobora gutanga cm 40 mugihingwa kashe ikikijwe nubushyuhe bwa induction.
Dore ibyo tubwira abakiriya gukora mbere yo kwiyemeza gutumiza amajwi.
