TV mlongoti “Polyachka” kwa nthawi yaitali DVB-T2 phwando: kusankha amplifier, wamakono, unsembe.

Ambiri ogwiritsa ntchito wailesi yakanema ya digito akudabwa ngati mlongoti wopukutidwa ungagwirizane ndi kulandila kwa DVB-T2 . Vutoli lidayamba kuchitika mwachangu pambuyo poti boma lidachitapo kanthu kuti ziwonjezeke komanso kuti zigawo zambiri zidalumikizidwa ndi wailesi yakanema ya digito .

Kodi grill yaku Poland ndi yoyenera kulandila TV ya digito?

Mlongoti wa Polish mesh pa nthawi ina unafalikira mofulumira m’dziko lonselo ndipo unatchuka pakati pa ogwiritsa ntchito ambiri. Chida ichi ndi chodzichepetsa pakukonza ndipo pambuyo pa kukhazikitsa sikutanthauza zina zosinthidwa. Kubwera kwa DVB-T2 kuwulutsa kwa digito mdziko muno, ogwiritsa ntchito adayamba kupeza ma amplifiers osiyanasiyana amtundu uwu wa antenna, kuwalola kuti agwire chizindikiro cha digito ndikuwulutsa pa TV.
Gulu la antenna palokha ndi Broadband. Mwanjira ina, zida zotere zimatha kulandira zizindikiro zosiyanasiyana zamitundu yonse ya mita ndi ma decimeter. Katundu wapaderayu amalola chipangizocho kugwira ma siginecha a digito pa TV mumtundu wa DVB-T2.

Grille yaku Poland si njira yabwino kwambiri yomwe imagwiritsidwa ntchito polandila mtunda wautali wamakanema a digito. Izi zimachitika makamaka chifukwa chakuti chipangizocho chimafuna kusinthidwa ndi kukonzanso chisanayambe kugwira ntchito mumtundu womwe ukufunidwa.

Makhalidwe apamwamba a mlongoti waku Poland

Mitundu ya Poles imagwira ntchito kuchokera ku 40 mpaka 800 MHz. Izi zimakupatsani mwayi wolandila ma siginecha ndikuwonera mapulogalamu a pa TV kuyambira chaneli 1 mpaka 20. Ndi kuwongolera pang’ono ndi kulumikizana kwa amplifier, zimakhalanso zotheka kuwona makanema apa TV kuchokera pa 21 mpaka 69. Kuphatikiza apo, pakukonza koyambira kwa mitundu yonse ya tinyanga tamitundu yosiyanasiyana, pali kukulitsa kwa siginecha mpaka ma decibel 13, monga komanso kugwedezeka kwa mafunde a 300 ohms. Miyeso ya zida ndi yaying’ono (80×60 cm), kulemera kwake ndi 1.5 kg. Mndandanda wa zigawo za mlongoti mukamagula ndizochititsa chidwi:

• vibrator yogwira (DMV, MV);
• ma vibrator (otsogolera);
• njanji zomangirira mizere yoyambira ya ma waveguides ndi nyumba zapulasitiki;
• phiri la antenna ndi chowunikira;
• midadada otsika voteji;
• mitundu yosiyanasiyana ya amplifier pakusankha kwa wogula;
• mapulagi okhazikika kuti agwirizane.

Zingwe za coaxial zomwe zimafunika kuti zigwirizane ndi chipangizochi kwa womasulira zimagulidwa mosiyana.

Kodi mlongoti wa Polyachka TV umagwira ntchito bwanji mukalandira chizindikiro cha digito?

Zoyambira sizikutanthauza kugwiritsa ntchito zida zolandirira ma TV 10 kapena 20 omwe amagawidwa mdziko lonse.. Mulimonsemo, mpaka kusinthidwa kovomerezeka kwa antenna kuchokera kwa wopanga kuwonekere, muyenera kusintha nokha kuti mukwaniritse chizindikiro chofunikira. Ndi kukonzanso koyenera, grille yaku Poland imayankha bwino pakulandila kwa digito kwakutali. Pali kachulukidwe kakang’ono ka mwayi woti, chifukwa cha mtundu wofananira wolandila ma siginecha, mlongoti amatha kujambula chithunzicho ndikuwulutsa mawu popanda kusinthidwa. Komabe, chizindikirocho chidzakhala chofooka, ndipo zidzakhala zovuta kukonza nthawi zonse. Amplifier yokhazikika yomwe imabwera ndi magulu a antenna siyeneranso kugwira ntchito ndi wailesi yakanema ya digito. Iyenera kukwezedwa kuti ipititse patsogolo kulandila kwa siginecha. Zotsatira zabwino zimatheka pokhapokha ngati mlongoti uli pafupi ndi nsanja yobwerezabwereza.

Kusankha chokulitsa chachitsulo cha Polish cholandirira ma siginolo aatali a DVB-T2

Popanda amplifier, latisi yaku Poland silingalandire ndikusintha ma sign omwe akubwera a m’badwo watsopano. Woyambira amplifier mu mlongoti waku Poland amapangidwa padera. M’masitolo apawailesi zamagetsi, zitha kugulidwa osapitilira ma ruble 200.
Posankha amplifier, zonse zimatengera mtundu wamtundu womwe wogwiritsa ntchito ayenera kugwiritsa ntchito kuti alandire. Wailesi iliyonse ya amplifier yokhazikika imakhazikika pogwiritsa ntchito njira yokhotakhota pagawo lalikulu la mlongoti. Ndiko komwe, mkatikati mwa zidazo, pomwe bokosi laling’ono lotetezedwa limayikidwa. Kupyolera mu bolodi anaika mmenemo, mukhoza kukwaniritsa kusintha zotsatira za kulandira chizindikiro.

Ntchito yayikulu ya ma antenna amplifiers a digito ndikukweza mawonekedwe azizindikiro zapa TV zomwe zikubwera. Zitsanzo zilizonse pamsika zimakulitsa bwino ma siginecha omwe adalandira – mtundu wawo umadalira mtunda kuchokera kwa wobwereza wamkulu.

Kuti musankhe chitsanzo cha amplifier, kutengera mphamvu ndi mtunda wa nsanja ya TV, mukhoza kutsogoleredwa ndi tebulo:

M’masitolo komanso pamsika wawayilesi, mutha kupeza omasulira ambiri a mlongoti waku Poland. Pali zitsanzo zambiri zoti musankhe. Onsewo ali ndi miyeso yofanana, koma amasiyana mumtundu wolandila komanso mphamvu yazizindikiro kuchokera ku 30 mpaka 48 decibel. Ma board a amplifier onse, kuphatikiza omwe amalandila chizindikiro cha digito, ali ndi voteji ya 12 volts, yomwe amalandila kuchokera kumagetsi otsika a 220 mpaka 12 volts. Magetsi onse omwe akubwera omwe amapita ku bolodi lalikulu lomwe lili pa antenna amadutsa pulagi yapadera yokhala ndi capacitor yomangidwa. Ndi chithandizo chake, pali kugawanika kukhala mphamvu ndi chizindikiro chomwe chikubwera.

Posankha mtundu woyenera wa amplifier wa antenna osiyanasiyana, mutha kulumikizana ndi anansi anu kapena kuwona mtundu womwe adayika padenga. Pogwiritsa ntchito tebulo, mutha kuwerengera kuchuluka kwa chizindikiro cha digito chomwe chidzafika pazida zanu.

Mavuto omwe angakhalepo poyesa kulandira TV ya digito pogwiritsa ntchito latisi yaku Poland

Nthawi zambiri tinyanga zaku Poland zokhala ndi amplifier ndi magetsi zimatha kukumana ndi zovuta zotsatirazi:

• chizindikirocho chimayamba kutha kwathunthu;
• pokhazikitsa mawayilesi a kanema wawayilesi, sikelo yowonetsa kuchuluka kwa siginecha imayamba kukwera mwachangu mpaka 100 kapena, mosiyana, imatsikira ku 0;
• pali phwando poyamba, koma pakapita nthawi amayamba kufooka kapena kutha kwathunthu;
• chithunzicho chimayamba pang’onopang’ono, ma cubes amawonekera, phokoso limayamba kuchita chibwibwi;
• mwa mayendedwe 20 omwe akupezeka pawayilesi yaulere, 10 okha ndi omwe amawonetsedwa – ndipo ngakhale ndi chithunzi choyipa;
• ngati mlongoti uli pamtunda wochepa mpaka mamita 2.5-3, ndiye kuti magalimoto odutsa pamsewu angayambitse chizindikirocho kuti chiyambe kutaya.

Zonsezi zimapangitsa kuti pakhale kufunikira kokonzanso bwino kuti alandire bwino ndikupewa zovuta zosiyanasiyana.

Ngati mumvetsera kulandirira kwa digito ndikuwona mita ya mulingo ikuyamba kukwera ndikugwa mwachangu, zikutanthauza kuti ikutayika. Mwa kuyankhula kwina, chizindikiro cha digito chotere kudzera pa Pole sichiyenera kulembedwa. Pankhaniyi, zida ziyenera kusinthidwa.

Kodi nditani ngati gululi Polish savomereza DVB T2?

Ngati Pole savomereza DVB T2 ndipo sachita mwa njira iliyonse zoikamo Buku, izi sizingakhale vuto la TV. Ogwiritsa ntchito ambiri amapeza kuti phindu loyambira lomwe likupezeka pazida zamasiku ano za plasma ndi LCD ndizokwanira kufikira mulingo woulutsira digito. Malinga ndi ogulitsa ambiri, ma TV amakono amatha kulandira chizindikiro popanda kulumikiza tinyanga. Komabe, pochita, zimakhala kuti munthu atalikirana ndi chizindikiro chobwerezabwereza, kulandila kumakhala koipitsitsa. Mkhalidwe umenewu umaonekera kwambiri m’madera akutali kwambiri m’dzikoli, omwe posachedwapa ayamba kugwiritsa ntchito wailesi yakanema ya digito. Ma repeater towers akuyenera kuwonjezera kukulitsa kotero kuti okhala m’deralo athe kukwaniritsa zomwe zili m’matauni. Nthawi zambiri, chifukwa cha chizindikiro choipa pamene kulandira DVB-T2 ndi kuchuluka mphamvu. Womasulira amene sanasankhidwe moyenerera angathe kuonjezera zomasulira zomwe zimatuluka, zomwe zimabweretsa kusokoneza. Pali njira zinayi zowongolera vutoli ndikupeza bwino kulandira ma TV a digito. Kusintha kwa mlongoti waku Poland wa DVB T2 wamakono: https://youtu.be/SiIg8yWLaY8

Njira yoyamba

Ngati wogwiritsa ntchito ali ndi magetsi oyendetsedwa, ndiye kuti sipadzakhala vuto ndi kusintha mphamvu ya wobwereza. Kawirikawiri olamulira oterowo ali ndi ulamuliro pamanja. Kuti muchepetse mphamvu yomwe ikubwera, ndikwanira kutembenuza zomangira zomwe zili pakatikati pa amplifier motsatana. Pankhaniyi, mphamvu yamagetsi imatsika pansi pa 12 volts. Malire ochepera ndi 2 volts. M’pofunika kuchepetsa mlingo wa siginecha pamene kuwulutsa kwa TV kuli, kuti muzitsatira momwe zimasonyezedwera pamasewero ake pa TV. Mukasintha mlingo wa chizindikiro, kusintha kwake kwa khalidwe lachiwonetsero kudzachitika ndi kuchedwa pang’ono, kotero muyenera kuyembekezera pang’ono.

Njira yachiwiri

Mitundu yaposachedwa yapa TV ili ndi ma tuner osiyanasiyana omwe amatha kulandira chizindikiro cha digito. Pankhaniyi, mungagwiritse ntchito chinyengo pang’ono kuti muchepetse kwambiri mphamvu zomwe zimaperekedwa ku adaputala ya mlongoti. Izi zigwiritsa ntchito doko la USB kuchokera pa TV. Kuti muchite izi, muyenera kuchita zotsatirazi:

1. Tengani chingwe cha TV ndikuyika pulagi ya TV.
2. Gulani adaputala yomwe imakupatsani mwayi wopereka mphamvu ku mlongoti kudzera padoko la USB.
3. Lumikizani adaputala ku doko ndikuwongolera chingwe chamagetsi muchowonjezera cha mlongoti.

Mtengo wa adaputala yotere ya USB yamphamvu sikudutsa ma ruble 300. Imapezeka pafupifupi m’masitolo onse amagetsi ndipo sichifuna luso lapadera kuti muyike.

Njira yachitatu

Ngati pali bokosi lapamwamba lolandirira TV ya digito kunyumba, mutha kuwongolera mphamvu kuchokera pamenepo kupita ku amplifier ya mlongoti. Pankhaniyi, m’malo mwa ma volts 12 omwe adayikidwa, chokulitsa chomwe chili pamwamba pa mlongoti sichilandira ma volts opitilira 5 kuchokera pabokosi lapamwamba kudzera pa chingwe chawayilesi cholumikizidwa kale.
Zomwe muyenera kuchita ndikutsata njira zitatu zosavuta:

1. Konzani pulagi wamba wa TV pa chingwe cha TV.
2. Lumikizani bokosi lapamwamba ku TV.
3. Tsegulani mndandanda wa bokosi la set-top ndikusankha chinthu chomwe mphamvu ya antenna imatsegulidwa.

Malingana ndi chitsanzo cha bokosi lokhazikitsira pamwamba, menyu ndi njira yoyendetsera ma antennas akhoza kusiyana, choncho muyenera kutchula malangizo omwe adadza ndi chipangizocho.

Njira yachinayi

Mutha kuyesa ndikuzimitsa mphamvu ku mlongoti. Nthawi zina (malingana ndi malo a mlongoti ndi wobwerezabwereza), chizindikirocho chikhoza kubwera motere. Kuti muchite izi, muyenera kuchita zotsatirazi:

1. Tengani TV.
2. Konzani chingwe cha TV chokhala ndi pulagi.
3. Lumikizani chingwe ku bokosi lokhazikitsira pamwamba ndi mlongoti molunjika popanda mphamvu.

Njirayi siigwira ntchito nthawi zonse, chifukwa mphamvu imatha kukhala ziro, ndipo chizindikirocho chidzazimiririka kuyambira pomwe kanema wawayilesi akuyatsidwa.

Kukwera kwa antenna

Funso lina lodziwika bwino pakati pa ogwiritsa ntchito ndi komwe kuli bwino kuyika komanso momwe mungayikitsire bwino grille yaku Poland. Choyamba, muyenera kuphunzira mosamala zambiri pankhaniyi mu malangizo omwe amabwera ndi zida, zomwe zikuwonetsa magawo akulu oyika chipangizocho. Zida zoyambira za mtundu uliwonse wa mlongoti zimakhala ndi mlongoti wapadera wokonzera mlongoti. Kuti muteteze mlongoti ku mast, muyenera kugwiritsa ntchito chosungira chophatikizirapo. Izi zitha kuchitika nthawi yomweyo pansi mpaka nthawi yomwe mlongoti umayikidwa pamtunda wofunikira.

Musanayambe kukweza mlongoti ndi kukonza, mwachitsanzo, padenga, muyenera kukonzekera chingwe cha mlongoti, komanso chingwe champhamvu, chomwe chimagwirizanitsidwa bwino nthawi yomweyo chikakwera pa chipangizo cha chipangizo.

Ponena za kusankha kwa kutalika ndi malo a wolandira chizindikiro cha digito palokha, magawo apa nthawi zonse amakhala payekha ndipo amadalira komwe wogwiritsa ntchito amakhala. Mukakhazikitsa Pole, tikulimbikitsidwa kutsatira zotsatirazi:

1. Lumikizani cholandila chizindikiro ku TV.
2. Ikani voteji pa chokulitsa chizindikiro, cholumikizidwanso ndi mlongoti.
3. Dziwani malo okhudzana ndi nsanja yapa TV yapafupi.
4. Tembenuzirani gulu la antenna kupita ku nsanja ya TV.

Kuti muwongolere bwino kulandirira, kwezani pang’onopang’ono cholandila chizindikiro pamtengo. Panthawi yomwe chithunzi ndi phokoso zimakhala zapamwamba kwambiri, muyenera kukonza mast ndi antenna pamalo awa.

Wogwiritsa ntchito akatha kukonza mawaya onse kuti chipangizocho chisindikizidwe kuchokera kunja, chiyenera kuphimbidwa ndi msoko ndi guluu wopanda madzi. Izi zikuthandizani kuti mukwaniritse bwino kwambiri kulandira ma siginecha, kupewa kuthekera kwa chinyezi kulowa mkati. Mlongoti waku Poland amatha kulandira mafunde amitundu yokhazikika kuchokera mbali imodzi. Mukatembenuza mlongoti kupita ku nsanja, imangolandira chizindikiro cholowera. Kuti muwongolere bwino polandirira, ngati pali nsanja zingapo za kanema wawayilesi mozungulira, ndikofunikira kukhazikitsa zolandila zokhala ndi mitundu yofananira kwa iwo. Onerani kanema wamomwe mungakhazikitsire mlongoti wa Polack kuti alandire bwino pa TV ya digito: https://www.youtube.com/watch?v=2nPuYzAL0ug Yakwezedwa, Mlongoti wokonzedwa bwino komanso wosasunthika wa mtundu wa Chipolishi umagwira ntchito yabwino kwambiri yolandirira mawayilesi amakono apawailesi yakanema. Kukweza kwa zida izi kumapezeka kwa aliyense wogwiritsa ntchito ndipo sikufuna khama kapena ndalama zambiri.
