Ukulungisa DVRs ngumnikazi izandla: umdwebo, imiyalelo, izincomo, kanye nokubuyekeza

DVRs Modern anemisila zokuvikela izinga okusezingeni eliphezulu. Noma kunjalo, ngezinye izikhathi bantule ukuze ugweme ukuhluleka ahlukahlukene. On imodeli yedivayisi iyafana. Standard isikimu DVR kuhlanganisa processor, isixhumi kanye ephrintiwe wesifunda ibhodi.

Ikhamera elikulo ngokusebenzisa isitimela esikhethekile. Isignali idluliselwa nge photoresistor. Futhi DVRs capacitors efakwe zezinhlobo ezahlukene. Abanye onobuhle zisebenzisa module nge iyunithi inkumbulo.

Okweqile isibonelo DVR Gmini HD90

Lapho ebilayo elangeni ukulungisa DVR Gmini HD90 ngezandla kumele kuqale nge uhambo ibhodi wesifunda. Ngokuvamile inkinga iba e photoresistors. Ashisa kakhulu fuses ayikwazi abavikele. Ukuhlola DVR, udinga ukususa imodeli ikhava. Okulandelayo, udinga ukususa ikhamera bese ngokucophelela uyasikrufulula ephrintiwe wesifunda ibhodi. Uma ezikhumulweni fiphaza bese kudingeke ukushintsha ngokuphelele. Ukumaka iqukethe imininingwane ohlangothini reverse.

izinkinga Sound e DVR: imiyalelo ngokuxazulula inkinga kanye impendulo Professionals

izinkinga Sound zenzeka kaningi. Ukulungisa imoto DVR ngezandla zabo kulesi simo kumele kuqale nge luhlolo mojuli. Ngezinye izikhathi inkinga itholakala Dynamics, kodwa lokhu akuvamile kwenzeka. Ukuhlola module ikhamera, ukhipha ikhava ye-DVR.

Ngaphezu kwalokho okudingeke ukuba unqamule iluphu nokuvikeleka ikhamera. Uzokwazi ukuba uyasikrufulula ephrintiwe wesifunda ibhodi. kufanele kube modulator kulokhu eduze isixhumi. Udinga ukuhlola oxhumana. Uma ukholwa ukuthi umbono ochwepheshe ', kungenzeka ukuzama ukwenza izilinganiso ukumelana wesifunda. Nokho, lokhu kudinga umhloli. Ngokwesilinganiso, ukumelana module kumele singeqi 55 ohms.

Izinkinga ne uhlelo lokusebenza on isibonelo Viaccess 605 umthengi Izibuyekezo

Uma ukholelwa ukuthi ukubuyekezwa abathengi, avame sibhekene nezinkinga ngenxa yesistimu yokusebenza. Ngokuvamile, lokhu kwenzeka lapho ezilimele eshiya modulator. Kulokhu kungenzeka ukulungisa yezandla zabo. Viaccess DVR 605 ke kudingeka akuhlole. Ngenxa yale njongo, isivalo is bathinteka futhi bahlolwe oxhumana kwangaphandle PCB.

Lokhu kulandelwa ngqo nokuhlola modulator. Ukuze wenze lokhu, nqamula ngokucophelela ikhamera bese ikhebula. Isinyathelo esilandelayo ukususa modulator nge ukufakwa kokumqoka kuphela. Ngokuvamile, inkinga itholakala oxhumana kushaywa. Kulesi simo, into ngeke kudingeke ukushintsha ngokuphelele. Le modeli isethwe modulator wire hlobo.

Balungise isixhumi kusuka DVR

Isixhumi at DVR unesibopho yokudlulisela isiginali kusuka modulator. Uyaphula phansi ngokuvamile isinyathelo lokukhanda. Ukulungisa DVRs ngezandla zabo kuleli cala ilula ngempela ukwenza. Imodeli kuqala nge isikulufa cap. Ngaphezu kwalokho, ukwenza ukulungiswa ngezandla zabo DVRs (kungakhathaliseki kwimodi) iyadingeka izohlola ephrintiwe wesifunda ibhodi, kanye modulator.

Uma they are bonke ukuze, ungakwazi ukususa isixhumi. Ngezinye izikhathi othintana nabo bangase overheat. Kulokhu, ukulungisa DVR cishe kungenakwenzeka. Uma oxhumana nabo kungukuthi kabana, udinga ukusebenzisa esebenzisa futhi ukususa into. Isinyathelo esilandelayo ukuze uhlole valve kuso. ukubaluleka ukumelana kumele singeqi ohms 50. Uma umhloli kubonisa ukuphambuka kusuka kuyinsakavukela ke, kuzodingeka solder isixhumi entsha.

Hlola nezixhumi

Intambo yamandla kusuka DVR ixhunyiwe nge isixhumi. Ngezinye izikhathi uxhumano sinqamukile futhi idivayisi uyayeka ukusebenza. Ukulungisa DVRs ngezandla Kulezo zimo, kufanele uqale nge test enethiwekhi. Ukuze lokhu kuyadingeka ukuze athuthukise imodeli. PCB akufanele baphazamiseke. Isixhumi itholakala zezindlu eduze isixhumi. Ukuze uyibuke, kufanele ukuhambisa bebheke plate skid. Ngemva kwalokho, izisekelo base kuyadingeka ukuze ungamumbi. Lokhu kungenziwa kusetshenziswa screwdriver. Uma imininingwane umonakalo obonakalayo mechanical, khona-ke uyoba ukushintshwa. Thenga nezixhumi esitolo ngeke kube nzima. Nokho, umuntu kufanele azi nokulungiswa ngqo.

Njengoba ezothatha isikhundla ebhodini wesifunda e-DVR

PCB DVR iqoqo izakhi ukuphathwa uhlelo. Lapho behluleka, idivayisi akusebenzi. Ukulungisa DVRs ngezandla zabo kuleli cala kungenziwa ngokususa ikhava. Ukuze ususe PCB, udinga ukufakwa kokumqoka kuphela. Kulesi sigaba kubalulekile ilimaze amplifier, esemgwaqweni kude naye. Ngemva ukhupha PCB hlola zonke izikhala nokuhlanza nabo.

Izinkinga isitimela esuka DVR "Kark le Q3"

Uma ukholelwa ukuthi ukubuyekezwa abathengi ke lokhu izinkinga DVR lesi sitimela lapho kaningi. ingxenye wathi kuyinto kungenasisekelo kakhulu futhi ebucayi okushisa ezimbi. Ikhodi inqamuka, nje balahlekelana ngekhamera, kodwa idivayisi inkumbulo nge PC isatholakala. Ukulungisa DVR "Karki" ngezandla zabo uma zokugwema ukuphuka iluphu kufanele kuqale kokukhipha ikhava. Ukuze uthole ukuthi ingxenye wathi, kuyodingeka ukususa ephrintiwe wesifunda ibhodi.

Ngemva kwalokho, unqamule ikhamera ngqo. Zephyr kusuka DVR unamathele nge Isixhumi okhethekile. Ukuze wamkhulula, kuyodingeka usebenzise ummese. Kulokhu, kubalulekile ilimaze wire ukuthi isuka ibhethri. Isinyathelo esilandelayo ukususa ngokucophelela loop. Uma kukhona izimpawu ezibonakala umonakalo, okusho ukuthi idinga ukushintshwa. Ngemva kokufaka ingxenye entsha, udinga nje kabusha agobe isixhumi uphinde ulungise isiqeshana ngokuqinile.

Esikhundleni photoresist ngesibonelo DVR "Navigator"

Uma ukholelwa ukuthi ukubuyekezwa abathengi, okweqile elangeni ngesikhathi onobuhle photocell ngokuvamile liyashona (engezansi ibonisa umdwebo wiring of DVR "Navigator"). Ukulungisa izandla zakho Kulezo zimo zingenziwa. Endaweni yokuqala kuyodingeka ukhipha ikhava bese uyasikrufulula ephrintiwe wesifunda ibhodi. Photoresistor imodeli iseduze epholisayo. Ukuze uthole kuso, musa nqamula ikhamera.

Vele ikhebula nokunqamula iyunithi. Uzokwazi ukubuka iseli Photoelectric. Kubukeka sengathi isikhulumi ezihlangene. Ogibele isici wathi nge wire okuholela isixhumi. Uma inkinga ingabe-ke, kufanele ukwazi ukusebenzisa i-Blowtorch. Burnout photoresist udinga ukuthenga entsha ingxenye. Ibeke ngensimbi nokunamathisela ngomthofu akunzima.

Ukulungisa module ngesibonelo DVR "Karki Q2 kuyinto"

I module ku DVR kudingeka ukulawula ikhamera. Lapho isignali ukungasebenzi ihlinzekwa kuze kwimemori iyunithi. Esimweni esinjalo kungenzeka ukulungisa yezandla zabo. DVR "Karki Q2 kuyinto" le njongo kumele inqanyuliwe. Kutholwe eduze ibhodi module wesifunda. Kodwa ukuze uwufinyelele, umuntu kufanele aqale unqamule iyunithi.

Landelayo kuzodingeka ukususa ikhamera isitimela. Ngaphandle kwalokho, asinakuba ukubona module, eyakhelene distributor. Phansi contact ezimbili ingxenye elise. Kwezinye izimo, baye zishe ngenxa izifunda okufutshane. Ukuze uxazulule le nkinga, module kumele zisuswe kanye kabusha soldered. Kunzima ukubhekana nenkinga enjalo. Kulokhu-ke kungcono ukuxhumana sesevisi. Nokho, imbangela yokwehluleka kungabuye zanqwabelana uthuli. Ukuze ukuxazulula le nkinga, wena nje kudingeka ukuhlanza oxhumana nge swab ukotini kanye kabusha babuthane DVR.

Efingqa

Lokho kusho, umuntu akufanele singayinaki imithetho ukusetshenziswa DVR. Uma kudingekile, ukuhlola imodeli, ungakwazi ukubamba njalo owakho. Nokho, ngaphambi ukulungisa idivayisi kumele ukuhlola ubukhulu umonakalo futhi banqume benolwazi. Ngezinye izikhathi kungcono zihlanganisa DVR sesevisi futhi uthintane nge onguchwepheshe.
