I-EAS (I-Electronic Article Surveillance), eyaziwa nangokuthi isistimu yokuvimbela ukwebiwa kwempahla ye-elekthronikhi, ingesinye sezinyathelo zokuphepha zempahla esetshenziswa kakhulu embonini enkulu yokudayisa.I-EAS yethulwa e-United States maphakathi nawo-1960, ekuqaleni eyayisetshenziswa embonini yezingubo, iye yandisa amazwe angaphezu kuka-80 nezifunda emhlabeni jikelele, kanye nezicelo ezitolo ezinkulu, ezitolo ezinkulu, ezimbonini zezincwadi, ikakhulukazi ezitolo ezinkulu (indawo yokugcina impahla). ) izicelo.Uhlelo lwe-EAS luqukethe izingxenye ezintathu: Inzwa, Isivali, Ilebula ye-Electronic kanye ne-Tag.Amalebula e-elekthronikhi ahlukaniswe abe amalebula athambile futhi aqinile, amalebula athambile anenani eliphansi, anamathiselwe ngokuqondile ezimpahleni eziningi “eziqinile,” amalebula athambile awakwazi ukuphinda asetshenziswe;amalebula aqinile anezindleko eziphezulu zesikhathi esisodwa, kodwa angasetshenziswa kabusha.Amalebula aqinile kufanele afakwe izicupho ezikhethekile zezinzipho zezinto ezithambile nezingena ngaphakathi.Amadekhoda ngokuvamile angamadivayisi angaxhunywanga anobude obuthile bokukhipha amakhodi.Lapho othatha imali ebhalisa noma efakwa esikhwameni, ilebula ye-elekthronikhi ingaqoshwa ngaphandle kokuxhumana nendawo yokukhipha kazibuthe.Kukhona nezinto zokusebenza ezihlanganisa idekhoda kanye nesithwebuli sebhakhodi ye-laser ndawonye ukuze kuqedelwe ukuqoqwa kwezimpahla kanye nokuqopha kanyekanye ukuze kube lula umsebenzi we-cashier.Le ndlela kufanele isebenzisane nomphakeli webhakhodi ye-laser ukuze kuqedwe ukuphazamiseka phakathi kwakho kokubili futhi kuthuthukiswe ukuzwela kokuqopha.Izimpahla ezingabhaliwe ziyasuswa enxanxatheleni yezitolo, futhi i-alamu ngemva komtshina (ikakhulukazi umnyango) izocupha i-alamu, ukuze kukhumbuze othatha imali, amakhasimende kanye nonogada benxanxathela yezitolo ukuthi babhekane nakho kusenesikhathi.
Mayelana nokuthi isistimu ye-EAS ithola inkampani yenethiwekhi, kunezinhlelo eziyisithupha noma eziyisikhombisa ezihlukene ezinezimiso ezihlukile.Ngenxa yezici ezihlukile zenkampani yenethiwekhi yokuthola, ukusebenza kwesistimu nakho kuhluke kakhulu.Kuze kube manje, amasistimu e-EAS ayisithupha avele ama-electromagnetic wave systems, i-microwave system, i-radio/radio frequency system, i-frequency division system, i-self-alarm intelligent system, kanye ne-acoustic magnetic systems.I-electromagnetic wave, i-microwave, izinhlelo zomsakazo / i-RF zivele ngaphambili, kodwa zilinganiselwe ngomgomo wazo, akukho ukuthuthukiswa okukhulu ekusebenzeni.Isibonelo, isistimu ye-microwave nakuba iphuma ekuvikelweni okubanzi, ukufakwa okulula nokuvumelana nezimo (isb. kufihlwe ngaphansi kukakhaphethi noma ukulenga kusilingi), kodwa okusengozini yoketshezi olufana nokuvikela umuntu, sekuhoxile kancane kancane emakethe ye-EAS.Uhlelo lokwabelana ngemvamisa luyilebula eliqinile kuphela, elisetshenziselwa ukuvikela izingubo, alikwazi ukulisebenzisa esitolo esikhulu;njengoba uhlelo lwe-alamu oluhlakaniphile lusetshenziselwa ikakhulukazi izinto ezibalulekile njengemfashini ye-premium, isikhumba, ijazi loboya, njll.;i-acoustic magnetic system iyimpumelelo enkulu kubuchwepheshe bokulwa nobugebengu be-elekthronikhi, ithuthukise uhlelo lokwebiwa kwe-elekthronikhi kubathengisi abaningi kusukela yethulwa ngo-1989.
Izinkomba zokuhlola ukusebenza kohlelo lwe-EAS zifaka izinga lokutholwa kwesistimu, umbiko wamanga wesistimu, ikhono eliphikisana nemvelo, izinga lokuvikela insimbi, ububanzi bokuvikela, uhlobo lwezimpahla zokuvikela, ukusebenza / usayizi wamalebula aphikisana nokwebiwa, okokusebenza kokukhipha uzibuthe, njll.

(1) Izinga lokuhlola:
Izinga lokutholwa libhekisela enanini lama-alamu lapho inombolo yeyunithi yamalebula avumelekile idlula ezindaweni ezihlukene endaweni etholwayo ngezindlela ezihlukene.
Ngenxa yokuma kwamanye amasistimu, umqondo wezinga lokutholwa kufanele usekelwe esilinganisweni sokutholwa kwezinga kuzo zonke izinkomba.Ngokwemigomo emithathu esetshenziswa kakhulu emakethe, izinga lokutholwa kwamasistimu kazibuthe we-acoustic liphezulu kakhulu, ngokuvamile lidlula ama-95%;Amasistimu omsakazo/i-RF aphakathi kuka-60-80%, kanti amagagasi kagesi ngokuvamile aphakathi kuka-50 no-70%.Isistimu enezinga eliphansi lokutholwa kungenzeka ibe nenani lokuvuza lapho impahla ikhishwa, ngakho izinga lokutholwa lingenye yezinkomba zokusebenza eziyinhloko zokuhlola ikhwalithi yesistimu yokulwa nobugebengu.

(2) Ukuphutha Kwesistimu:
I-alamu yamanga yesistimu isho i-alamu ecushwa ilebula okungeyona eyeba isistimu.Uma into engekho ilebula icupha i-alamu, izoletha ubunzima kubasebenzi ukuze bahlulele futhi bayiphathe, futhi ibangele nokungqubuzana phakathi kwamakhasimende nenxanxathela yezitolo.Ngenxa yomkhawulo wesimiso, izinhlelo zamanje ze-EAS ezivamile azikwazi ukukhipha ngokuphelele i-alamu engamanga, kodwa kuzoba nomehluko ekusebenzeni, isihluthulelo sokukhetha isistimu ukubona izinga le-alamu elingamanga.

(3) Ikhono lokumelana nokuphazanyiswa kwemvelo
Uma okokusebenza kuphazanyiswa (ikakhulukazi amandla kagesi nomsindo ozungezile), isistimu ithumela isignali ye-alamu lapho kungekho muntu odlulayo noma kungadluli into ye-alamu ecushiwe, into ebizwa ngokuthi umbiko wamanga noma ukuzixwayisa.
Uhlelo lweRadio / RF luthambekele ekuphazamisekeni kwemvelo, luvame ukuzicula, ngakho-ke amanye amasistimu afaka amadivaysi e-infrared, okulingana nokwengeza inkinobho kagesi, kuphela lapho abasebenzi besebenzisa uhlelo, bevimba i-infrared, uhlelo luqala ukusebenza, akekho odlulayo. , isistimu isesimweni sokulinda.Nakuba lokhu kuxazulula ukuvuma izono lapho kungekho muntu odlulayo, kodwa namanje akakwazi ukuxazulula isimo sokuvuma uma othile edlula.
Isistimu ye-electromagnetic wave nayo isengozini yokuphazamiseka kwemvelo, ikakhulukazi imidiya kazibuthe kanye nokuphazamiseka kokunikezwa kwamandla, okuthinta ukusebenza kohlelo.
Isistimu kazibuthe ye-acoustic ithatha ibanga eliyingqayizivele lokukhala futhi ibambisane nobuchwepheshe obuhlakaniphile, isistimu ilawulwa yi-microcomputer nesofthiwe ukuze ibone ngokuzenzakalelayo umsindo ozungezile, ukuze ikwazi ukuzivumelanisa kahle nemvelo futhi ibe nekhono elihle lokulwa nokuphazanyiswa kwemvelo.

(4) Izinga lokuvikela insimbi
Izimpahla eziningi ezitolo ezinkulu nasezitolo ezinkulu zithwala izinto zensimbi, njengokudla, ugwayi, izimonyo, izidakamizwa, njll., kanye nemikhiqizo yazo yensimbi, njengamabhethri, amapuleti eCD/VCD, izinto zokulungisa izinwele, amathuluzi ehardware, njll.;kanye nezinqola zokuthenga nobhasikidi bokuthenga abahlinzekwa yinxanxathela yezitolo.Umthelela wezinto eziqukethe insimbi kusistimu ye-EAS ikakhulukazi umphumela wokuvikela welebula yokungeniswa, ukuze idivayisi yokutholwa yesistimu ingakwazi ukubona ubukhona belebula obusebenzayo noma ukuthi ukuzwela kokutholwa kwehliswe kakhulu, okuholela kusistimu khipha i-alamu.
Okuthinteka kakhulu ukuvikela insimbi uhlelo lomsakazo/i-RF RF, okungenzeka kube ngomunye wemikhawulo eyinhloko yokusebenza komsakazo/i-RF ekusetshenzisweni kwangempela.I-Electromagnetic wave system nayo izothintwa yizinto zensimbi.Uma insimbi enkulu ingena endaweni etholwayo yesistimu yegagasi logesi, isistimu izovela into ethi "stop".Uma kudlula inqola yensimbi nobhasikidi wokuthenga, ngisho noma izimpahla ezikuyo zizoba namalebula asebenzayo, ngeke zikhiphe i-alamu ngenxa yesivikelo.Ngaphezu kwemikhiqizo yensimbi emsulwa efana nebhodwe lensimbi, uhlelo lukazibuthe lwe-acoustic luzothinteka, futhi ezinye izinto zensimbi / ucwecwe lwensimbi, inqola yokuthenga yensimbi / ubhasikidi wokuthenga nezinye izinto zesuphamakethe ezivamile zingasebenza ngokujwayelekile.

(5) Ububanzi bokuvikela
Inxanxathela yezitolo idinga ukucabangela ububanzi bokuvikela besistimu yokulwa nobugebengu, ukuze ingagwemi ububanzi phakathi kwezisekelo phezu kwezinkuni, okuthinta amakhasimende ngaphandle nangaphakathi.Ngaphandle kwalokho, izinxanxathela zezitolo zonke zifuna ukuba nezindawo zokungena neziphuma ezibanzi.

(6) Ukuvikelwa kwezinhlobo zezimpahla
Izimpahla ezisesuphamakethe ngokuvamile zingahlukaniswa zibe izigaba ezimbili.Olunye uhlobo yizimpahla “ezithambile,” njengezingubo, izicathulo nezigqoko, izimpahla zokunitha, lolu hlobo oluvame ukusebenzisa ukuvikelwa kwelebula eliqinile, lungasetshenziswa kabusha;olunye uhlobo yizimpahla “eziqinile,” njengezimonyo, ukudla, ishampoo, njll., kusetshenziswa ukuvikelwa kwelebula ethambile, i-antimagnetization ku-cashier, ukusetshenziswa okuvamise ukulahlwa.
Kumalebula aqinile, izimiso ezihlukahlukene zezinhlelo zokulwa nobugebengu zivikela izinhlobo ezifanayo zezimpahla.Kodwa kumalebula athambile, ayahluka kakhulu ngenxa yamathonya ahlukene avela ezinsimbi.

(7) Ukusebenza kwamalebula aphikisana nokweba
Ilebula elimelene nokwebiwa liyingxenye ebalulekile yalo lonke uhlelo lwe-elekthronikhi lokulwa nobugebengu.Ukusebenza kwelebula yokulwa nobugebengu kuthinta ukusebenza kwalo lonke uhlelo lokulwa nobugebengu.Amanye amalebula asengozini yomswakama;abanye abagobi;abanye bangacasha kalula emabhokisini ezimpahla;ezinye zizofaka imiyalelo ewusizo entweni, njll.

(8) Imishini ye-Demagnetic
Ukwethenjwa kanye nokulula kwemishini yokwehlisa amandla nakho kuyizici ezibalulekile ekukhetheni uhlelo lokulwa nokweba.Njengamanje, amadivaysi athuthuke kakhulu e-demagnetization awathinteki, akhiqiza izinga elithile lendawo ye-demagmagnetization.Uma ilebula esebenzayo idlula, i-demagnetization yelebula iqedwa ngokushesha ngaphandle kokuxhumana ne-demagmagnetization, eyenza kube lula ukusebenza kwe-cashier futhi isheshise isivinini se-cashier.
Amasistimu e-EAS avame ukusetshenziswa ngokuhambisana namanye amasistimu okulwa nobugebengu, ajwayelekile ngokuqapha kwe-CCTV (CCTV) kanye nokuqapha kwe-cashier (POS/EM).Uhlelo lokuqapha ukheshi lwenzelwe ukuthi abaqoqi bemali baxhumane nesamba esikhulu semali nsuku zonke futhi bajwayele ukweba.Isebenzisa ubuchwepheshe bokugqagqana phakathi kwesixhumi esibonakalayo sokusebenza kwe-cashier kanye nesikrini sokuqapha se-CCTV ukuze kuqinisekiswe ukuthi abaphathi benxanxathela yezitolo bayasazi isimo sangempela somuntu ophatha imali.
I-EAS yesikhathi esizayo izogxila kakhulu ezicini ezimbili: Uhlelo Lwelebula Lomthombo womgqekezi (Ukumaka Umthombo) kanti enye i-Wireless Recognition Technology (Smart ID).Ngenxa yokuthi i-Smart ID ithonywa ukuvuthwa kobuchwepheshe bayo nezinto zentengo, ngeke isetshenziswe abasebenzisi ngokuqondile ngokushesha.
Uhlelo lwelebula yomthombo empeleni luwumphumela ongenakugwemeka webhizinisi ukuze kwehliswe izindleko, kuthuthukiswe ukuphathwa futhi kwandiswe izinzuzo.Ukusetshenziswa okunzima kakhulu kwesistimu ye-EAS ukulebula nge-elekthronikhi ezinhlobonhlobo zezinto, okwandisa ubunzima bokuphatha.Isixazululo esingcono kakhulu sale nkinga futhi isisombululo sokugcina ukudlulisela umsebenzi wokulebula kumkhiqizi womkhiqizo, futhi ufake ilebula emelene nokweba emkhiqizweni noma emaphaketheni ekukhiqizeni umkhiqizo.Ilebula yomthombo empeleni iwumphumela wokubambisana phakathi kwabathengisi, abakhiqizi, nabakhiqizi bezinhlelo zokulwa nobugebengu.Ilebula yomthombo yenza ukwanda kwezimpahla ezithengisekayo, okulethela amakhasimende ukunethezeka okwengeziwe.Ngaphezu kwalokho, ukubekwa kwelebula nakho kufihlwe kakhulu, kunciphisa amathuba okulimala, futhi kuthuthukise ukusebenza kahle kokulwa nokweba.
