Pangani-tokha kukonza kutali kwa TV: momwe mungakonzere zolumikizirana, kubwezeretsa mabatani

Chiwongolero chakutali ndichowonjezera pa TV yanu chomwe chimapangitsa kukhala kosavuta kusintha matchanelo, kuyatsa ndi kuzimitsa chipangizocho, ndikugwiritsa ntchito zida zina za Smart TV. Kugwiritsa ntchito pafupipafupi komanso mosasamala kungayambitse kusagwira bwino ntchito komwe kumapangitsa kuti chikhale chopanda ntchito. Kuti athetse vutoli, m’pofunika kukhala ndi lingaliro la mfundo yoyendetsera ntchito zakutali, zovuta zomwe zingatheke, komanso njira zothetsera vutoli ndi kupewa kuti athe kuchepetsa mwayi wawo m’tsogolomu.

Kapangidwe ndi mfundo zogwirira ntchito za remote control

Msika wowongolera kutali ndi wosiyanasiyana ndi zida zamawonekedwe ndi makulidwe osiyanasiyana. Zipangizo zonse zimakhala ndi zinthu 4:

1. Chimango.
2. Lipirani.
3. Keyboard matrix.
4. Batiri.

Bungweli liri ndi zovuta zamagetsi zamagetsi. Izi zikuphatikizapo:

1. Keyboard microcontroller.
2. Quartz resonator.
3. linanena bungwe transistor siteji.
4. Infrared LED.

Kukonza bolodi lakutali[/ mawu] Mfundo yogwiritsira ntchito chipangizocho ndikuti pali ma microcircuits pa bolodi, iliyonse yomwe ili ndi udindo wake. ndondomeko. Kukanikiza batani kumatseka nyimbo. Imakonzedwa ndi microcontroller. Kenako mndandanda wa zilembo umapangidwa ndikutumizidwa kwa wolandila chipangizocho pogwiritsa ntchito kuwala kwa infuraredi pafupipafupi. Kugwira ntchito kwa microcontroller kumathandizidwa ndi resonator ya quartz. Mafupipafupi ake ndi pafupifupi 250,000 kHz. [id id mawu = “attach_4515” align = “aligncenter” wide = “550”]

Mitundu yamavuto

Musanayambe kukonza chowongolera chakutali, muyenera kudziwa mtundu wa vutolo. Mavuto omwe amapezeka kwambiri ndi awa:

1. Palibe yankho pamene mabatani onse akanikizidwa.
2. Mabatani a pa remote ndi ovuta kusindikiza.
3. Mabatani ena athyoledwa.
4. Mitsempha ndi kusweka chifukwa cha kugunda kapena kugwa.
5. Mabatani omata.
6. Mavuto ndi mabatire.

Chipangizo Diagnostics

Mabatani onse akutali akapanda kugwira ntchito, mabatire ayenera kusinthidwa kaye. Pa mlandu wofooka, kuchitapo kanthu pakudina kamodzi kapena kawiri ndikotheka, pambuyo pake chipangizocho chimasiya kugwiranso ntchito. Ngati kusintha mabatire sikunathandize, ndiye kuti izi ndizovuta ndi zamagetsi. Choyamba muyenera kuyang’ana kutali. Izi zitha kuchitika pogwiritsa ntchito kamera ya foni yam’manja. Chipangizocho chimalunjikitsidwa ku kamera yokhala ndi LED, pambuyo pake batani lachisawawa limagwiridwapo ndipo chithunzi chimatengedwa. Bulu logwira ntchito mu chithunzi lidzatulutsa malo owala. Izi zikuwonetsa vuto ndi TV.
Diode yayatsidwa – batani likugwira ntchito

Chenjerani! Nthawi zina mabatani angapo sagwira ntchito. Pankhaniyi, vuto liri mu zolumikizana kapena zokutira zawo.

Momwe mungasankhire chowongolera chakutali cha TV

Choyamba, muyenera disassemble chipangizo. Theka la thupi la chiwongolero chakutali chikhoza kukhazikitsidwa ndi zomangira, latches kapena kukhala ndi fixation kawiri. Zomangira zili muchipinda cha batri. Pambuyo pomasula zomangirazo, muyenera kusiyanitsa mosamala mlanduwo. Ngati sichikugwira ntchito, ndiye kuti pali ma latches mu remote control. Mutha kugwiritsa ntchito khadi la pulasitiki kapena screwdriver ya flathead kuti mulekanitse magawo amilandu. Chidacho chiyenera kulowetsedwa mu mzere wolumikizana wa magawo awiri a thupi. Izi ziyenera kuchitidwa pasanathe kuwonekera phokoso.

3. Kusagwira ntchito kwa quartz resonator. Mutha kudziwa kuwonongeka mwa kugwedeza bolodi. Ngati pali rustle, gawolo liyenera kusinthidwa.
4. Ndi mphamvu yamphamvu, njira zoyendetsera zimatha kutuluka. Kuti chipangizocho chizigwira ntchito, chiyenera kugulitsidwanso. Ngati izi sizingatheke, chingwe chimodzi chamkuwa chikhoza kulumikizidwa m’malo mwake. Pambuyo kulumikiza, iyenera kukhazikitsidwa ndi guluu.

Mosamala! Musagwiritse ntchito asidi panthawi ya soldering. Sichimachotsedwa pa bolodi, zomwe zingayambitse kuwonongeka kwa ojambula m’tsogolomu. Ndikwabwino kugwiritsa ntchito rosin kapena flux ina yomwe ilibe acid.

Momwe mungakonzere chowongolera chakutali cha TV ngati mabatani sagwira ntchito kapena kumamatira

Nthawi zambiri pamakhala mavuto pansi pa kiyibodi. Zinthu zotsatirazi zingayambitse izi:

• kusasamalira mosasamala kwa chipangizocho;
• madzi otayika;
• kukhudzidwa kwanthawi yayitali ndi dzuwa;
• manja akuda.

Kuti mukonze vutoli, muyenera kuyeretsa bolodi ndi mabatani. Chigawo cha ntchito:

1. Choyamba muyenera kuchotsa mabatire ndikuchotsa chowongolera chakutali.
2. Kokani bolodi.
3. Kuti mutsuke tchipisi, mumafunika timitengo takhutu tomwe taviika mowa.
4. Tsitsani malo olumikizana nawo mu paketi ya batri. Pamaso pa zolengeza zoyera kapena zobiriwira, mutha kugwiritsa ntchito sandpaper yabwino.
5. Sambani nyumbayo bwinobwino m’madzi a sopo. Kuti muyeretse bwino, ndi bwino kugwiritsa ntchito mswachi.

Kuyeretsa bolodi ndi ntchito yosavuta koma yodetsa nkhawa[/ mawu] Momwe mungakonzere chowongolera chakutali cha TV ndi manja anu – momwe mungatsegule chipangizocho, kukonza ndikubwezeretsa mabatani, yeretsani bolodi: https://youtu.be/OMKh7245x10

Kuyang’ana mabatire

Komanso, chowongolera chakutali sichingagwire ntchito chifukwa cha mabatire akufa. Chifukwa cha 80% ya mafoni onse opita kumalo othandizira ndizovuta ndi mabatire. Mukhoza kuyang’ana zomwe zingatheke posintha mabatire kapena kuwayang’ana pa multimeter. Izi ziyenera kuchitika muyeso wa DC panopa pamtundu wa 10A. Ngati mumasankha malire otsika, mukhoza kuwotcha fusesi. Kuyesa kumachitidwa bwino padera pa batri iliyonse. Kuyeza kwa magetsi kumachitidwa bwino pamachitidwe ogwiritsira ntchito. Ngati pali oxides, madipoziti kapena dzimbiri pamalo olumikizana, ayenera kuchotsedwa ndi gulu lotanuka kapena sandpaper yopangidwa bwino.

Kusaka zolakwika

Ngati chowongolera chakutali sichitetezedwa ndi chivundikiro cha pulasitiki, ndiye pakapita nthawi, bolodi ndi maziko a mphira, pamodzi ndi fumbi, amasonkhanitsa mafuta osungira m’manja. Zotsatira zake, kulumikizana kwa mabatani kumawonongeka kapena kuwonongedwa kwathunthu. Pofuna kupewa kuwonongeka kwa chipangizocho, ndikofunikira kuchita zodzitetezera munthawi yake. Mukachotsa chivundikiro chapamwamba chakutali, muyenera kulabadira zolumikizana zomwe zili pa bolodi. Zitha kukhala zophimbidwa ndi graphite kapena alkaline. Graphite imapatsa ojambulawo mtundu wakuda, kotero ndizosavuta kusokoneza ndi dothi. Kuchotsa kolakwika kwa zokutira kudzatsogolera kuti kukhudzana kudzawonongeka. Pamaso pa kuipitsidwa pang’ono, kuyeretsa kwanuko kungakhale kochepa. Pachifukwa ichi, ndodo za makutu wamba ndizoyenera. Iwo ayenera wothira mowa, ndiyeno mosamala kuchotsa zolengeza. Kugwiritsa ntchito zosungunulira zina kungawononge zolumikizana nazo.
Pakakhala kuipitsidwa kwambiri, tikulimbikitsidwa kutsuka bolodi limodzi ndi mphira m’madzi ofunda a sopo pogwiritsa ntchito mswachi wokhala ndi zofewa zofewa. Pambuyo pake, muyenera kutsuka bwino zotsalira za sopo ndikuwumitsa zigawozo ndi chowumitsira tsitsi. Ngati chipangizocho chikukana kugwira ntchito, muyenera kuyang’ana chipinda cha batri kuti chikhale ndi okosijeni kapena mapindikidwe a ojambula. Ma okosijeni amatha kutsukidwa ndi mpeni. Ngati kukhulupirika kwa olumikizanawo kuphwanyidwa, zopukutira kapena zozungulira mphuno zidzafunika. Ngati sizingatheke kukhazikitsa kasupe kuchokera ku chipinda cha batri, ndiye kuti chowongolera chakutali chiyenera kuchotsedwa. Pambuyo pochotsa ndi kuyeretsa chipangizocho, muyenera kuyang’ana malo opangira zida za wailesi, makamaka ma infrared diode ndi ma batire. M’malo awa, ming’alu ya mphete nthawi zambiri imapanga. M’pofunikanso kuyendera bolodi palokha kwa kinks ndi ming’alu,

Zofunika! Ngati chipangizocho chagwetsedwa, kristalo ikhoza kusweka. Ndi vutoli, ndi bwino kulankhula pafupi ndi malo utumiki kukonza chipangizo.

Dzichitireni nokha zowongolera zakutali kunyumba ndi njira zotsogola: https://youtu.be/rdI8vdxQ7Yw

Kodi ndingatani ngati sindingathe kukonza ndekha chowongolera chakutali?

Nthawi zina, ndizosatheka kukonza chowongolera chakutali nokha. Muzochitika izi, pali njira ziwiri:

1. Tengani chipangizocho kumalo operekera chithandizo.
2. Gulani chowongolera chatsopano pawayilesi kapena kuyitanitsa kutumiza kwa chipangizo choyambirira.

Mabatire amayenera kusinthidwa osataya asidi[/ mawu] Kupeza analogi kudzawononga ndalama zochepa. Pa nthawi yomweyo, mukhoza kugula multifunctional chipangizo kuti angathe kulamulira zipangizo zingapo. Pafupifupi ogwiritsa ntchito onse amatha kukonza zazing’ono zokhudzana ndi chiwongolero chakutali: ndizotheka kusintha mabatire kapena kumata malo atsopano olumikizana popanda kudziwa zambiri. Pakawonongeka zovuta, tikulimbikitsidwa kulumikizana ndi malo othandizira kapena kugula analogue.
