Em e-electromagnetic library anti-theft system, Em Electromagnetic Jewelry Store anti-theft system

Umtapo wezincwadi we-EM/isitolo sobucwebe esilwa nokwebiwa yisisombululo esishibhile esisebenzisa ubuchwepheshe be-electromagnetic ukufeza ukuphikiswa kokwebiwa kwempahla.. Uhlaka oluyinhloko lwedivayisi yokulwa nokweba lwenziwe ngezinto zokulingisa zepulasitiki, futhi amaphaneli aseceleni enziwe ngamaphaneli ekristalu amasha angagugi futhi asobala. Inama-alamu anembile namazinga okutholwa aphezulu kakhulu, futhi yenzelwe imitapo yolwazi emincane nephakathi nendawo, izitolo zezincwadi, amakhemisi, Izitolo zezimonyo, kanye nezitolo zobucwebe.
Lolu hlelo lungangeza amamojula omsebenzi wezibalo, futhi ingahlonyiswa ngezibalo zesivakashi eziqongelelekayo zansuku zonke/zomlando.
Indlela yokufaka: Ingafakwa ngezindlela ezine: ngaphambi kokungcwatshwa, ukusika, i-wire trough, kanye nokulungiswa kwamapuleti aphansi.
Kunezinketho ezimbili zokucushwa kwesistimu:
1. Isistimu eyodwa ingaxhuma izimpondo ezimbili (ingqikithi ye 2 isilwane), futhi ibanga lokufaka phakathi kwezinti lingafinyelela ku-90cm.
2. I-antenna eyodwa eyinhloko ingaxhuma izimpondo ezimbili zesibili (ingqikithi ye 3 isilwane), futhi ibanga lokufaka phakathi kwezinti lingafinyelela ku-90cm.

Izici
Umkhiqizo unomqondo oqinile wokuhleleka, elula futhi ephanayo
Uhlelo lusebenzisa ubuchwepheshe bokucubungula isignali yedijithali ye-DSP, futhi izinga le-alamu liphezulu
Uhlelo lusebenzisa i-digital-DMPD (ukutholwa kwezigaba eziningi ezinamandla) ubuchwepheshe, okwenza uhlelo luzinze
Isixhumi esibonakalayo esibekiwe sesiginali singasetshenziswa ukuze kuzuzwe ukuxhumana okuvumelanayo nokuqapha
Ihambisana nokucaciswa okuhlukahlukene kwemigqa kazibuthe enefrikhwensi efanayo
Thola amalebula ambozwe nge-aluminium foil
