I-Intercom Yevidiyo Yekhebula Yenethiwekhi
I-CASHLY Network Cable Video Intercom System:
* Ikhebula le-UTP elingu-1 CAT-5E kuphela ekamelweni * Isifundi sekhadi le-ID/IC
* Isiteshi segumbi sixhumeke esandleni
* Engeza umsebenzi Isitoreji sesithombe se-Colour Room-stations
* Intambo engu-1 CAT-5E STP kuphela edingekayo ukuze kube noxhumo lwenethiwekhi oluzinzile noluthembekile
* I-Fiber optic iyahambisana nebanga elide kuze kufike ku-50km uxhumano lwenethiwekhi
* Ikhiphedi yesiteshi-emnyango enokukhanya ukuze isetshenziswe ebusuku * Hlangana nanoma yisiphi isakhiwo saphansi
I-Analog villa intercom system wuhlelo lwe-intercom olususelwe ekudluliselweni kwezintambo ezine. Iqukethe isiteshi esingaphandle se-villa kanye ne-monitor yangaphakathi. Isekela i-intercom ebonakalayo, ukubhekwa kwevidiyo, ukulawula ukufinyelela kanye neminye imisebenzi, futhi inikeza isisombululo esiphelele sesistimu ye-intercom yevidiyo esekelwe ezindlini zomndeni owodwa.

I-topology yenethiwekhi evame ukusetshenziswa ukunqanyulwa kwesakhiwo sebhasi, ayisekeli inethiwekhi eyisiyingi noma emise okwenkanyezi. Yonke i-node iyi-serial exhunywe ibhasi eyodwa iyisinqumo esihle, esithombeni esingenhla, i-topology yenethiwekhi evamile yesistimu ye-A8-05B iyaboniswa. Ama-N node axhunywe kunethiwekhi ye-multipoint. Ngesivinini esiphezulu nemigqa emide, ukumelana nokunqanyulwa kuyadingeka kuzo zombili iziphetho zomugqa ukuze kuqedwe ukucabangela. Sebenzisa ama-resistors angu-100 Ω kuzo zombili iziphetho (udinga kuphela uma ubude bezintambo > 2km). Inethiwekhi kufanele yakhelwe njengomugqa owodwa onamaconsi amaningi, hhayi njengenkanyezi. Nakuba ubude bekhebula obuphelele bungase bube bufushane ekucushweni kwenkanyezi, ukunqanyulwa okwanele akusenakwenzeka futhi ikhwalithi yesiginali ingase yehle kakhulu. Kumdwebo 1 obonise okulandelayo, b, d, f ukuxhumana okulungile kanye no-a, c, e ukuxhumana okungalungile.
Umdwebo 1
Uma usebenzisa i-Shield network wire (STP), Kufanele igcine ukuqhubeka kongqimba oluyisivikelo olubushelelezi, futhi ixhume uMhlaba endaweni eyodwa, njengoba kukhonjisiwe kumdwebo.
Kudingeka ucingo
Isistimu isebenzise intambo ye-CAT-5E UTP ne-STP.
Ungakhetha kanjani ikhebula le-CAT-5E elifanelekayo?
Ukumelana nentambo ngayinye kufanele kube ≤35Ω uma ubude buba ngu-305M (ubude be-FCL).
Isiteshi-semnyango kuya ku-Power Supply sisebenzise i-RVV4*0.5, ukukhiya i-RVV2*0.5 esetshenzisiwe.
Isexwayiso:
Isithombe sesiteshi-mnyango ngeke sibonakale ngokugcwele esikrinini se-Visual Room-station uma Isiteshi segumbi sihluke kakhulu kugesi wevidiyo, ezindaweni ezifanele ebhasini lokwakha ukuze kwandiswe ugesi kungaxazulula le nkinga. Ukunikezwa kwamandla okujwayelekile kwevidiyo okuvela endaweni ebonakalayo Isiteshi segumbi lebanga eliphakeme alikwazanga ukudlula amamitha angama-30.

Kudingeka i-vice yomhlathi kuphela
Isithombe somphumela
Ngenxa yokuthi indinganiso ye-RJ-45 yenzelwe ukusetshenziswa kwangaphakathi kuphela, ayinabo umswakama futhi ingcoliswa kalula noma ifakwe i-oxidized. Uma iNhloko ye-RJ-45 iphukile, kukhona ochwepheshe abaphethe amathuluzi ochwepheshe adingekayo ukuze kulungiswe iphutha, lokhu kuzoholela ezindlekweni zokulungisa eziphakeme.
I-Scotchlok yikho kanye esikudingayo. Ngaphezulu kweminyaka engama-45 edlule, i-3M yethula isixhumi sokuqala somkhakha sokufuduka kwe-insulation - i-Scotchlok Connector UR. Namuhla, ngesidingo esikhulayo samanethiwekhi anesivinini esikhulu kanye nomkhawulokudonsa ophezulu, uchungechunge oluphelele lwezixhumi ze-3M namathuluzi seluphinde lwavela futhi. Sicela uvakashele ku-www.3M.com ukuze uthole ulwazi olwengeziwe lwe-Scotchlok.
Ukubuka konke Kwesistimu
Isixazululo Izici
Umsebenzi we-Visual Intercom
Umsebenzisi angashayela ngqo imonitha yasendlini ocingweni lomnyango ukuze abone i-intercom ebonakalayo nomsebenzi wokuvula. Umsebenzisi angasebenzisa futhi i-monitor yangaphakathi ukuze ashayele amanye ama-monitor angaphakathi ukuze abone umsebenzi we-intercom wendlu ngendlu.
Umsebenzi Wokulawula Ukufinyelela
Umsebenzisi angashayela umqaphi ongaphakathi esiteshini esingaphandle emnyango ukuze avule umnyango nge-intercom ebonakalayo, noma asebenzise ikhadi le-IC nephasiwedi ukuvula umnyango. Umsebenzisi angabhalisa noma akhansele ikhadi le-IC futhi asethe iphasiwedi esiteshini esingaphandle.
Umsebenzi we-alamu yokuphepha
Umsebenzisi angasebenzisa imonitha yasendlini ukuze abuke ividiyo yesiteshi sangaphandle emnyango, futhi abuke ividiyo yekhamera ye-analog efakwe ekhaya.
