Ukuhambelana komfundi wekhadi kunye nabaqhubi beengcango ezizenzekelayo kuyaphumelela okanye kulahleke kwiindawo ezintathu: iprotocol, i-wiring, kunye nexesha lokudlulisa. Zilungise ezi zinto kwaye ukuhlanganiswa kuthatha imizuzu engama-90 - zilungise kwaye uya kulandela ukungaphumeleli okungapheliyo kangangeeveki.
TL;DR — Amanqaku abalulekileyo okuhlanganisa
- I-Wiegand iseyindlela emiselweyo yokufunda amakhadi akwi-85% nangaphezulu.— kodwa i-OSDP ifumana indawo kwiindlela ezintsha zokufakela ulwazi lwayo oluyimfihlo noluneendlela ezimbini.
- Isiphumo sokudluliselwa kwisilawuli sokufikelela kufuneka sihambelane nohlobo lokufaka i-trigger yomqhubi womnyango.— unxibelelwano olomileyo (NO/NC) xa kuthelekiswa ne-powered output, kwaye ububanzi be-timing pulse kufuneka bucwangciswe phakathi kwemizuzwana eyi-0.5 neyi-30.
- Uqwalaselo lweentambo ezintathu lugubungela i-95% yeemeko zokudibanisa:i-relay trigger ethe ngqo, i-controller-managed hold-open, kunye ne-fail-safe/fail-secure bypass yokudibanisa i-fire alarm.
- Umsebenzisi wethu womnyango otyibilikayo we-YF150 wamkela isixhobo esiqhelekileyo sokudibanisa esomileyokunye nexesha elihlengahlengiswayo lokubamba nokuvula ukusuka kwimizuzwana eyi-0 ukuya kwengama-60, okwenza ukuba ihambelane phantse nayo yonke inkqubo yokulawula ukufikelela kwimarike.
Kutheni Ukuhlanganiswa koLawulo loFikelelo kungaphumeleli — Kwaye Kutheni Kungaqhelekanga ukuba yimpazamo yoMsebenzi woMnyango
Igama lam ndingu-Edison, kwaye ndilawula imibuzo yeprojekthi yehlabathi kunye nezisombululo ezenziwe ngokwezifiso ze-OEM/ODM kwiNingbo Yufan Beifan Automatic Door Co., Ltd. Ndichithe iminyaka engaphezu kweshumi ndinceda abasasazi kunye nabathengi bokuthengwa kweprojekthi ukuba badibanise abaqhubi beminyango abazenzekelayo neenkqubo zokulawula ukufikelela - abafundi bekhadi, izikena zebhayomethrikhi, iinkqubo zokungena kwekhiphedi, kunye neeyunithi zokukhulula iminyango ezisekelwe kwi-intercom. Ngelo xesha, ndibone iingxaki ezifanayo zokudibanisa ziphindaphinda kumakhulu eeprojekthi, nokuba umlawuli wokufikelela yi-HID EdgeReader ye-$200 okanye iphaneli yeshishini ye-LenelS2 ye-$5,000.
Ipateni isoloko ifana: umfakeli uqhagamshela isiphumo somfundi wekhadi kwi-input yomqhubi womnyango. Isebenza ngexesha lokuqalisa ukusebenza. Emva kweeveki ezintathu, ucango luyasilela ukuvula ngamaxesha athile kwisiqinisekiso esisemthethweni - okanye okubi nangakumbi, luhlala luvuliwe ngonaphakade. Umnini wesakhiwo utyhola umqhubi womnyango. Kuthunyelwa ingcali. Umqhubi womnyango uvavanywa ngokugqibeleleyo eyedwa.Kuba ingxaki ihlala isenzeka kwaye umqhubi womnyango udlula yonke into yokuxilonga ezimeleyo, ngoko ke unobangela oyintloko — ukudibana kwentambo, iprotokholi, okanye ukungafani kwexesha kumda wokudibanisa — awufunyaniswa kangangeeveki.
Ndifuna ukuchaza ngqo indlela yokuthintela oku. Okulandelayo yireferensi yokudibanisa endiyithumela kuye wonke umntu ofake ikhadi ngaphambi kokuba adibanise isixhobo sokufunda ikhadi kwisixhobo sethu sokufunda.Umsebenzisi wocango olutyibilikayo oluzenzekelayo lwe-YF150— okanye nawuphi na umqhubi wocango oluzenzekelayo, nokuba kunjalo.Ngenxa yokuba ujongano lwesignali phakathi kolawulo lokufikelela kunye nokuzisebenzela ngokuzenzekelayo komnyango lumiselwe ngokulinganayo kulo lonke ishishini, ngoko ke imigaqo apha iyasebenza nokuba usebenzisa ziphi izixhobo zomenzi.
Ii-Interfaces ezintathu zoDibaniso: iProtokholi, iiNtambo, kunye nexesha
Ukuhlanganiswa kwekhadi ngalinye phakathi komsebenzisi nomfundi kubandakanya iindlela ezintathu ezahlukeneyo zokunxibelelana. Zonke kufuneka zichaneke ukuze inkqubo isebenze ngokuthembekileyo. Ndiza kuthetha ngazo ngokweenkcukacha.
Ujongano #1: Iprotokholi — iWiegand vs. iOSDP vs. iRS-485
Le protocol imisela indlela umfundi wekhadi anxibelelana ngayo nomlawuli wokufikelela — kwaye, ngezantsi, indlela umlawuli wokufikelela abonisa ngayo umqhubi womnyango ukuba avule.Kuba iWiegand ibisoloko iyindlela ephambili yokulawula ukufikelela ukususela ngeminyaka yoo-1980, ngoko ke malunga nama-85% abafundi bekhadi abafakiweyo kwizakhiwo zorhwebo basasebenzisa iWiegand. Yiprotokholi elula, elandelanayo: umfundi uthumela idatha yeziqinisekiso kumlawuli ngentambo ye-DATA0/DATA1. Umlawuli uqinisekisa iziqinisekiso aze anike amandla isiphumo se-relay. Umqhubi womnyango ubona ukuvalwa kwe-relay aze avule.
Ubulula bukaWiegand bubunamandla bayo — kunye nobuthathaka bayo. Idlulisela idatha yobungqina ngombhalo ocacileyo, ayinayo i-encryption, kwaye ayiniki mpendulo evela kumlawuli ukuya kumfundi. Ukuba umfundi uphazamisekile okanye i-wiring iphazamisekile, umlawuli usenokungazi. Yiyo loo nto.I-SIA(uMbutho wezoKhuseleko) uphuhlisiweI-OSDP (iProtokholi yeSixhobo esiLawulwayo esiVulekileyo), esebenzisa unxibelelwano lwe-RS-485 olusebenzisa i-encryption ye-AES-128 kunye nolawulo lweendlela ezimbini.
Kwi-integrator yomqhubi womnyango, umahluko weprotocol ubalulekile ngendlela ethile:Abalawuli be-OSDP banokuxela imeko yendawo yomnyango kwinkqubo yolawulo lokufikelelaUkuba umqhubi womnyango unesiphumo senzwa yendawo yomnyango (i-YF150 yethu inayo — iswitshi yereyi eqhutywa ngumagnethi evala xa ucango lufikelela kwindawo evulekileyo ngokupheleleyo), umlawuli we-OSDP unokujonga ukuba ucango luvuleke ngokwenene na emva kokuba kuboniswe isiqinisekiso esisemthethweni. NgeWiegand, umlawuli unika amandla i-relay kwaye ucinge ukuba ucango luvuliwe — akanandlela yokuqinisekisa.
Isinxibelelanisi #2: Ucingo — Uqhagamshelwano olomileyo, Imveliso eqhutywa ngamandla, kunye noCwangciso oluMiselweyo oluThathu
Kulapho ndibona khona iimpazamo ezininzi zocingo lwe-field. Isiphumo se-relay se-access controller kunye ne-trigger ye-cango operator kufuneka zivumelane ngohlobo lwesignali. Kukho iindlela ezintathu ezisemgangathweni zokumisela:
Uqwalaselo A: Uqhagamshelwano olomileyo, Oluqhelekileyo Luvuliwe (HAYI) — Umgangatho weHlabathi.Isilawuli sokufikelela sibonelela ngoqhagamshelwano lwereyila olungenawo umbane oluvala okomzuzwana (ngesiqhelo imizuzwana eyi-1-5) xa kufundwe isiqinisekiso esisemthethweni. Isixhobo sokufaka itrigger somsebenzisi womnyango senzelwe ukuvalwa koqhagamshelwano okomileyo. Xa ireyila ivala, umsebenzisi womnyango ubona ukuvalwa koqhagamshelwano aze aqalise umjikelo ovulekileyo. Olu luqwalaselo olusetyenziswa malunga nama-80% ofakelo kwaye luxhaswa ngumsebenzisi womnyango ozenzekelayo endakha ndadibana naye, kuquka zonke iimodeli zethu.Uluhlu lweemveliso ze-YFBF.
Ucingo lulula: ii-conductor ezimbini ukusuka kwi-relay output ye-access controller (NO kunye ne-COM) ukuya kwi-trigger input terminals ye-carry operator yomnyango. Yiyo leyo.Kuba i-relay ibonelela ngokwahlukana kwe-galvanic phakathi komlawuli wokufikelela kunye nomsebenzisi womnyango, ngoko ke ii-ground loops, ukungafani kwe-voltage, kunye ne-electrical ingxolo coupling — ezona mithombo zintathu zixhaphakileyo zokusilela kokuhlanganiswa okungapheliyo — ziyasuswa ngolu lungiselelo.
Uqwalaselo B: Isiphumo Esisebenza Ngombane (12V okanye 24V DC).Ezinye ii-access controllers — ingakumbi iimodeli ezindala kunye neenkqubo ezithile zokungena ezisekelwe kwi-intercom — zikhupha isignali enikwe amandla endaweni yoqhagamshelwano olomileyo. Umzekelo, i-controller isebenzisa i-12V DC kwi-trigger wire ngexesha lokuvula. Ukuba umqhubi womnyango ulungiselelwe ukufaka unxibelelwano olomileyo kwaye ufumana isignali enikwe amandla, isiphumo sinokuqala ekusebenzeni okwethutyana ukuya kumonakalo ongunaphakade wesekethe yokufaka. Nditshintshe iibhodi zolawulo zomqhubi womnyango ezintathu kwiminyaka emibini edlulileyo kuba abafakeli baqhagamshele i-powered output kwi-dry-contact input ngaphandle kokujonga i-voltage.
Uqwalaselo C: Ukhuseleko Olungaphumeleliyo / Ukhuseleko Olungaphumeleliyo kunye ne-Alarm yoMlilo.Kwizakhiwo zorhwebo, inkqubo ye-alamu yomlilo kufuneka ikwazi ukugqitha ulawulo lokungena kunye nokunyanzela iingcango ukuba zivuleke ukuze ziphume. Oku kufuna igalelo elahlukileyo le-trigger kumqhubi womnyango - i-terminal ye-alamu yomlilo (i-FAI) ethi, xa inikwe amandla okanye ingasebenzi (kuxhomekeke kwindlela ebekwe ngayo), inyanzele ucango ukuba luvuleke kwaye luhlale luvuliwe de imeko ye-alamu yomlilo iphele.Kuba iikhowudi zomlilo kwiindawo ezininzi zifuna ukuba iingcango ezizenzekelayo zivuleke xa i-alamu yomlilo ivuliwe., ngoko ke iingcingo ze-FAI kufuneka ziqinisekiswe ngexesha lokuqalisa ngovavanyo lwe-alamu yomlilo — kungekuphela nje ukujonga ukuqhubeka kwayo. Umgangatho we-National Fire Protection AssociationI-NFPA 101IKhowudi yoKhuseleko loBomi ilawula ezi mfuno eMelika, kwaye imigangatho efanayo iyasebenza nakwamanye amazwe.
Isinxibelelanisi #3: Ixesha — Ububanzi beRelay Pulse kunye noBude beHold-Open
I-timing interface yeyona nto ingaqhelekanga ekuhlanganisweni kolawulo lokufikelela — kwaye yeyona ivelisa uninzi lweefowuni zenkonzo. Kukho iiparameter ezimbini ze-timing ekufuneka zilungelelaniswe:
Ububanzi be-relay controller yokufikelela:Le yindlela i-relay yomlawuli ehlala ivaliwe ngayo emva kokufundwa kwesiqinisekiso esisemthethweni. Ii-defaults eziqhelekileyo zasefektri yimizuzwana eyi-1, 3, 5, okanye 10 - kwaye ixabiso lihlala licwangciswa kwisoftware yokulawula inkqubo. Ukuba ububanzi be-pulse bufutshane kakhulu, umqhubi womnyango usenokungayibhalisi i-trigger. I-YF150 yethu ifuna i-trigger pulse encinci ye-100 milliseconds (imizuzwana eyi-0.1), engaphantsi kakhulu kuyo nayiphi na i-realistic controller pulse width - kodwa ndidibene nabalawuli apho ububanzi be-pulse bubekwe ngengozi kwi-50 milliseconds ngexesha lokucwangcisa, kwaye umqhubi womnyango akazange aphendule.
Ixesha lokuvula umqhubi womnyango:Eli lithuba elihlala livuliwe emva kokufumana isignali yetrigger, ngaphambi kokuba iqale umjikelo wayo wokuvala. Kwi-YF150 yethu, oku kulungiswa ukusuka kwimizuzwana eyi-0 ukuya kwengama-60 nge-potentiometer ebhodini yokulawula. Ixesha elifanelekileyo lokubamba-ukuvula lixhomekeke kwisicelo: imizuzwana emi-3-5 yomnyango oqhelekileyo weofisi apho abantu bangena khona ngesantya esiqhelekileyo, imizuzwana eli-10-15 yokungena okufikeleleka kwizitulo ezinamavili nganyeI-ADAizikhokelo, kunye nemizuzwana engama-20-30 yeengcango zepaseji yemithwalo okanye yesibhedlele apho ii-gurneys kunye neenqwelo zezixhobo zifuna ixesha lokuvula umda.
Kuba i-relay pulse ye-access controller kunye ne-hold-open timer ye-cango operator zisetwa ngokuzimeleyo kwaye zihlala zicwangciswa ziingcali ezahlukeneyo., ngoko ke ndicebisa ukuba ubhale phantsi zombini izicwangciso kwingxelo yokugunyazisa kwaye unamathisele ilebheli ngaphakathi kwindlu yomqhubi womnyango. Xa kufika umnxeba wenkonzo emva kweenyanga ezintandathu — "umnyango uhlala uvuliwe ixesha elide kakhulu" okanye "umnyango awuhlali uvula xa ucofa ibheji yokuqala" — ingcali inokujonga izicwangciso ezibhaliweyo ngokuchasene noqwalaselo lwangoku ngaphantsi kwemizuzu emibini.
Isalathiso seeNtambo: Ukudibanisa i-YF150 kwiZilawuli zoFikelelo oluQhelekileyo
Ndifuna ukubonelela ngesalathiso esithile socingo kumqhubi wethu we-YF150, kuba ndiphendula le mibuzo qho ngeveki. Ibhodi yokulawula ye-YF150 inebhloko yesiphelo sokufaka i-trigger enikezelweyo eneziqhagamshelo ezibhalwe ngokucacileyo:
- IVULIWE— Faka i-trigger yokufaka isignali yokuvula ucango (ukuvalwa koqhagamshelwano okomileyo phakathi kwe-OPEN kunye ne-GND)
- I-GND— Isalathiso somhlaba wesignali
- Tshixa— Isiphumo sokudluliselwa kwesitshixo somnyango (sinikwa amandla xa ucango luvaliwe, ukuze kudityaniswe isitshixo se-electromagnetic)
- I-FAI— Igalelo le-interface ye-alamu yomlilo (inyanzela ucango luvuleke xa luvuliwe)
- I-POS— Isiphumo senzwa yendawo yomnyango (iswitshi yereed, ivaliwe xa ucango luvuleke ngokupheleleyo)
Ukuze kubekho udibaniso oluqhelekileyo lolawulo lokufikelela kunye nesiphumo sokudibanisa okomileyo, iingcingo ziqhutywa zii-conductor ezimbini:isilawuli AKUKHO → YF150 VULIWE, isilawuli COM → YF150 GND.Leyo yidayagram epheleleyo ye-wiring ye-80% yofakelo.
Kwizinto ezifuna ukuhlanganiswa kwe-alamu yomlilo, qhagamshela i-relay output yephaneli yokulawula i-alamu yomlilo kwi-terminal ye-YF150 FAI. Xa i-relay ye-alamu yomlilo ivala (okanye ivula, kuxhomekeke kulungiselelo), i-YF150 inyanzela ucango ukuba luvuleke kwaye ikhubaze umsebenzi wokuvala ngokuzenzekelayo de imeko ye-alamu yomlilo icocekile.Ngenxa yokuba iingcingo ze-alamu yomlilo kufuneka zijongwe ukuze zihlale zisemgangathweni — intambo ephukileyo kufuneka ibonise impazamo kwiphaneli ye-alamu yomlilo, ngoko ke uqhagamshelo lwe-FAI kufuneka lusebenzise ulawulo lwe-resistor end-of-line (EOL) ngokoyilo lwenkqubo ye-alamu yomlilo. Ndicebisa ukuba ulungelelanise olu cingo kunye nomthengisi we-alamu yomlilo ngexesha lokufakelwa kwe-rough, kungekhona emva kokuba umqhubi wocango efakiwe.
Iimeko Eziqhelekileyo Zokusombulula Iingxaki kunye Nezizathu Zazo Eziphambili
Kwiminyaka edlulileyo, ndiye ndaqokelela isiseko sedatha yengqondo sokusilela kokudibanisa ulawulo lokufikelela kunye nezona zinto zinokwenzeka. Nazi iimeko ezine endizibona rhoqo:
Uphawu: Ucango luvuleka xa kukho ibheji ebhalwe phantsi kodwa kwezinye azivuleki.Eyona nto inokwenzeka kukuba yingxolo yombane kwiintambo zetrigger — ingakumbi ukuba intambo yetrigger isebenza ngaxeshanye neentambo zamandla e-AC ngaphezu kweenyawo ezili-10 (iimitha ezi-3).Ngenxa yokuba igalelo le-YF150 trigger lisensitive edge (libona utshintsho oluvela kwi-open circuit ukuya kwi-closed circuit), ngoko ke ingxolo ebukhali kumgca we-trigger ingatolikwa njenge-trigger esebenzayo - okanye, ngokuqhelekileyo, inokufihla i-trigger yokwenyani. Isisombululo kukusebenzisa intambo ekhuselweyo kwiintambo ze-trigger, kunye nentambo ye-shield drain eqhagamshelwe emhlabeni kwisiphelo somlawuli kuphela. Okanye, ukuba ukuphinda ufake intambo akunakwenzeka, yongeza i-capacitor ye-ceramic ye-0.1 µF kuzo zonke ii-terminals ze-OPEN kunye ne-GND kumqhubi womnyango ukuze ucofe ingxolo ephezulu.
Uphawu: Ucango luvuleka ngokuqhelekileyo kodwa aluvalwa.Jonga useto lwesibali-xesha sokubamba-vula kuqala. Ukuba simiselwe kwi-maximum (imizuzwana engama-60 kwi-YF150 yethu), sinciphise siye kwixabiso elifanelekileyo lesicelo. Ukuba isibali-xesha simiselwe ngokuchanekileyo kwaye ucango alukavali, jonga isignali yenzwa yokhuseleko esebenzayo.Ngenxa yokuba i-sensor yokhuseleko ye-YF150 iyawugqitha umjikelo wokuvala — ukuba i-sensor ibona isithintelo, ucango aluyi kuvalwa nokuba ixesha libekwe njani., ngoko ke i-sensor yokhuseleko engalungelelananga okanye engcolileyo yeyona nto yesibini ixhaphakileyo yokuba "ucango aluyi kuvala" iinkonzo. Coca iilensi ze-sensor nge-isopropyl alcohol kwaye uqinisekise ukuba ihambelana ne-reflector okanye i-receiver.
Uphawu: Ucango luvuleka kwangoko xa uvula ngaphandle kokufundwa kwebheji.Oku phantse rhoqo kubonisa ukuba intambo yokufaka i-trigger imfutshane — nokuba sisikrufu se-staple okanye se-drywall singene kwintambo, okanye i-relay ye-access controller ibambeke ivaliwe. Nqamla iingcingo ze-trigger kwi-terminal block ye-YF150. Ukuba ucango luyeka ukuvuleka xa luvuliwe, ingxaki ikwi-access controller okanye kwi-wiring. Ukuba ucango luqhubeka luvuleka xa luvuliwe ngelixa iingcingo ze-trigger zivaliwe, ibhodi yokulawula ye-YF150 inempazamo — nxibelelana neqela lethu lenkxaso yobugcisa.Kuba igalelo le-trigger elifutshane lifana ngombane nesignali ye-trigger esebenzayo, ngoko ke umqhubi womnyango akanakukwazi ukwahlula phakathi kwezi zimbini — kwaye indlela ekuphela kwayo yokwahlula impazamo kukuqhawula intambo yesiqhushumbisi kumqhubi womnyango aze avavanye inxalenye nganye ngokwahlukeneyo.
Uphawu: Ukusebenza okwethutyana okuhambelana nemozulu.Oku ndikubona rhoqo kwiingcango zangaphandle apho isilawuli sokufikelela sifakwe khona kwivestibule engafudunyezwanga.Kuba ukufuma kwenzeka kwiindawo zokunxibelelana kweereyi xa umoya ofudumeleyo nofumileyo udibana neendawo ezibandayo zesinyithi, ngoko ke ii-relay contacts kwi-controllers ezifakwe ngaphandle zinokuphuhlisa i-oxidation enamandla okumelana nombane evelisa ukuvalwa okukhawulezileyo kwe-contact. Isisombululo kukucacisa ii-access controllers ezine-sealed, i-gas-filled relay (i-hermetically sealed) zokufakelwa kwangaphandle, okanye ukufaka i-enclosure heater encinci elawulwa yi-thermostat ukugcina i-controller ingaphezulu komphetho wombethe.
Ubungqina Bexesha Elizayo: Ukucwangcisa Ukuhlanganiswa Kolawulo Lokufikelela Kwakho kwi-OSDP kunye neziqinisekiso zeSelfowuni
Ndibuzwa ngakumbi ngabachazi beprojekthi: "Ngaba kufuneka siqhubeke sifake ii-Wiegand readers, okanye sifanele siqinisekise ikamva nge-OSDP?" Impendulo yam ixhomekeke kumhla weprojekthi kunye neemfuno zokhuseleko lwesakhiwo.
Ukuba isakhiwo siyavulwa kwiinyanga ezili-12 ezizayo kwaye imfuneko yokhuseleko ilula — ukufikelela kwiibheji zabasebenzi ngexesha leeyure zomsebenzi, akukho mfuneko yokulandelela uhlolo ngaphandle kwexesha elisisiseko kunye nokuya — iWiegand iselukhetho olufanelekileyo ngokupheleleyo. I-hardware ibiza kancinci, wonke uchwepheshe wolawulo lokufikelela uyazi indlela yokuyifaka, kwaye isebenza ngokuthembekileyo kuyo yonke i-operator yomnyango ozenzekelayo kwimarike.
Nangona kunjalo, ukuba iprojekthi inexesha leenyanga ezingama-24, ukuba iinkcukacha zokhuseleko zifuna unxibelelwano olufihliweyo, okanye ukuba umnini wesakhiwo ufuna ukuxhasa iziqinisekiso zeselula (ukufikelela okusekelwe kwi-smartphone nge-NFC okanye i-Bluetooth), ndicebisa kakhulu ukuba ucacise i-OSDP.Ngenxa yokuba abafundi be-OSDP kunye nabalawuli bahambelana ngasemva kunye neentambo zeWiegand — intambo efanayo ye-4-conductor ethwala iWiegand inokucinywa kwakhona kwi-OSDP RS-485., ngoko ke utyalo-mali lweziseko zombane lufana. Umahluko weendleko ukwizixhobo zokufunda kunye nezolawulo, nto leyo eyanciphayo: Abafundi be-OSDP ngoku baxabisa malunga ne-15-25% ngaphezulu kunee-Wiegand readers ezifanayo, ukusuka kwi-40-50% kwiminyaka emithathu eyadlulayo.
Kwicala lomqhubi womnyango, ukuhlanganiswa akutshintshi. Nokuba isilawuli sokufikelela sithetha iWiegand okanye i-OSDP, sisakhupha ukuvalwa kwereyi yoqhagamshelwano eyomileyo ukuze kuqalise umqhubi womnyango. Ukuvalwa kwereyi kuyafana ngombane nokuba iprotokholi iphezulu.Kuba umqhubi womnyango ubona kuphela imveliso yokudlulisela — hayi iprotokholi, ngoko ke ukhetho lwakho lweWiegand vs. OSDP alunampembelelo konke konke ekulungelelanisweni komqhubi womnyango. Lo ngumbuzo endiwuphendula rhoqo, kwaye impendulo isoloko ifana: umqhubi womnyango akanandaba.
Imibuzo ebuzwa qho
Ngaba abaqhubi beengcango zakho ezizenzekelayo basebenza nee-HID card readers?
Ewe. I-YF150 yethu kunye nabo bonke abaqhubi beengcango ezizenzekelayo ze-YFBF bayamkela i-dry contact contact trigger input eqhelekileyo, ehambelana nayo yonke i-HID card reader configuration xa idibene ne-access controller. I-card reader inxibelelana ne-access controller nge-Wiegand okanye i-OSDP. I-access controller inika amandla i-relay output xa ifunyenwe ngokusemthethweni. Loo relay closure ibangela i-carry operator. Akukho nanye indawo apho i-card reader inxibelelana ngokuthe ngqo ne-carry operator - i-access controller ihlala phakathi kwabo njengomlamli.Kuba ujongano lokudibanisa luyindlela elula yokuvala unxibelelwano olomileyo, ngoko ke ukuhambelana kuqhelekile kuzo zonke iimpawu zokufunda amakhadi kunye nolawulo lokufikelela.
Ubungakanani obuncinci be-trigger pulse obufunekayo kumqhubi womnyango wakho?
Iimodeli zethu ze-YF150 kunye nazo zonke iimodeli zangoku ze-YFBF automatic door operator zifuna i-trigger pulse encinci ye-100 milliseconds (imizuzwana eyi-0.1). Oku kungaphantsi kakhulu kobubanzi be-relay pulse yefektri phantse kuzo zonke ii-access controller ezikwimarike, ezihlala zihlala kwi-1-5 seconds. Imeko kuphela apho ububanzi be-pulse buba yingxaki kuxa ingcali itshintshe i-access controller ngesandla ukuya kwixesha elifutshane kakhulu le-relay - sibone iimeko ze-50-millisecond pulses apho umqhubi wethu womnyango angazibhalisanga. Isisombululo kukuqinisekisa ukuba useto lobubanzi be-relay pulse ye-relay ye-access controller buyi-200 milliseconds ubuncinane - kabini ubuncinane bethu, ukubonelela ngomda wokhuseleko.
Ngaba umqhubi womnyango wakho angadibana nenkqubo ye-alamu yomlilo xa ephuma ngexesha likaxakeka?
Ewe. Bonke abaqhubi beengcango ezizenzekelayo ze-YFBF baquka igalelo elizinikeleyo le-Fire Alarm Interface (FAI). Xa igalelo le-FAI livuliwe, ucango luvuleka ngoko nangoko kwaye luhlala luvuliwe de imeko ye-alamu yomlilo iphele, igqitha zonke ezinye iigalelo zolawulo kuquka i-access controller kunye ne-hold-open timer. Igalelo le-FAI linokucwangciswa ukuba livuleke okanye livalwe, kuxhomekeke kuyilo lwenkqubo ye-alamu yomlilo.Kuba ukuhlanganiswa kwe-alamu yomlilo ngumsebenzi wokhuseleko lobomi, ngoko ke ndicebisa ukuba umntu oza kusebenzisa i-alamu yomlilo, hayi umfaki wocango, enze uqhagamshelo lokugqibela lwe-FAI aze aqinisekise ukusebenza ngexesha lovavanyo lokwamkelwa kwenkqubo ye-alamu yomlilo.I-NFPA 101Ikhowudi yoKhuseleko loBomi (okanye elingana nayo yasekuhlaleni) kufuneka iqinisekiswe ligunya elinegunya (AHJ).
Luhlobo luni lwentambo olucebisayo kwiintambo ze-trigger phakathi komlawuli wokufikelela kunye nomsebenzisi womnyango?
Ndicebisa intambo ye-18-22 AWG ekhuselweyo ene-twisted-pair (Belden 8760 okanye efanayo) kuzo zonke iindlela zokuqhuba iintambo ze-trigger. Intambo ye-shield drain kufuneka iqhagamshelwe emhlabeni kwisiphelo solawulo lokufikelela kuphela - ukudibanisa i-shield kuzo zombini iziphelo kudala i-ground loop edibanisa ingxolo kwii-signal conductors. Kwi-runs ezingaphantsi kweenyawo ezingama-50 (iimitha ezili-15), intambo engagqunywanga iyamkeleka, kodwa ndisacebisa intambo ekhuselweyo kuba ixabiso elinyukayo limalunga ne-$0.15 ngenyawo kwaye isusa iifowuni zenkonzo ezinxulumene nengxolo.Ngenxa yokuba intambo yetrigger ine-voltage ephantsi (ngesiqhelo yi-12-24V DC) kwaye ayinawo amandla abalulekileyo ombane, ngoko ke ii-conductor ze-AWG ezingama-22 zanele ukubaleka ukuya kuthi ga kwiimitha ezingama-300 (iimitha ezingama-1,000). Kwimiba emide, sebenzisa i-18 AWG ukuqinisekisa ukuba ukuhla kwevolthi akuchaphazeli umda wokufunyanwa kokuvalwa kwereyila.
Ngaba ndingakwazi ukuqhagamshela ii-operators ezininzi zeminyango kwisiphumo esinye solawulo lokufikelela?
Ewe — kunye nomda omnye obalulekileyo. Isiphumo sereyila somlawuli wokufikelela kufuneka silinganiswe kwi-inrush current edibeneyo yazo zonke ii-inputs ze-trigger zomqhubi womnyango odibeneyo. Igalelo lethu le-trigger ye-YF150 litsala malunga ne-5 mA kwi-12V DC, ngoko ke isiphumo sereyila esinye sinokuqhuba ngokukhululeka ii-opharetha ze-YF150 ezingaphezu kwe-10 ngaxeshanye. Nangona kunjalo, ukuba ii-opharetha zomnyango zivela kubavelisi abahlukeneyo, qinisekisa i-trigger input current draw nganye kwaye uqinisekise ukuba itotali ayidluli kwinqanaba loqhagamshelwano lwereyila.Kuba oonxibelelwano bereyila banomlinganiselo omncinci wokutshintsha kunye nomlinganiselo ophezulu, ngoko ke ukudibanisa umqhubi womnyango omnye kuphela kwirelay elinganiswe nge-5A kwi-250V AC kunokubangela i-contact oxidation — umthwalo we-5 mA uphantsi kakhulu ukubonelela "ngomsinga omanzi" ogcina iirelay contacts zicocekile. Kwizinto ezifakelwe ucango olunye olunerelay ephezulu, yongeza i-resistor ye-1 kΩ ngaxeshanye kunye ne-carry operator input ukuze kwandiswe umsinga wokutshintsha ube malunga ne-12 mA, okwaneleyo ukugcina iirelay contacts zicocekile.
