LED kuratidza skrinizvigadzirwa zvemagetsi, uye dzimwe nguva panogona kunge paine mamwe matambudziko.Pazasi, isu tichazivisa akati wandei akajairika nzira dzekugadzirisa matambudziko.
01 Ndechipi chikonzero chemasekonzi mashoma emitsara inopenya kana yakasviba chidzitiro chidzitiro pa LED skrini payakatanga kuvezwa?
Mushure mekubatanidza iyo hombe screen controller kune komputa, HUB yekugovera bhodhi, uye skrini nemazvo, zvinodikanwa kupa a+ 5V simba rekupakune mutongi kuti ave nechokwadi chekushanda kwayo (panguva ino, usaibatanidza zvakananga ku 220V voltage).Panguva yekubatidzwa kwemagetsi, pachave nemasekonzi mashoma emitsara yakajeka kana "blurred screen" pachiratidziri, zvinova zvakajairika bvunzo zviitiko, zvichiyeuchidza mushandisi kuti skrini yave kuda kutanga kushanda zvakajairika.Mukati memasekonzi maviri, chiitiko ichi chinongonyangarika uye skrini ichapinda yakajairika yekushanda maitiro.
02 Sei isingakwanisi kutakura kana kutaurirana?
Zvikonzero zvekutadza kutaurirana uye kutadza kurodha zvakangofanana, izvo zvinogona kukonzerwa nezvikonzero zvinotevera.Ndapota enzanisa zvinhu zvakanyorwa nekushanda:
1. Ita shuwa kuti iyo control system hardware inofambiswa zvakanaka.
2. Tarisa uye simbisa kuti serial cable inoshandiswa kubatanidza mutongi inzira yakatwasuka, kwete crossover line.
3. Tarisa uye simbisa kuti serial port yekubatanidza waya haina kusimba uye hapana kusununguka kana kuvharirwa pamagumo ose.
4. Enzanisa LED screen control software nekadhi rekutonga rawakasarudza kusarudza yakarurama chigadzirwa modhi, nzira yekutumira, serial port nhamba, uye serial transmission rate.Seta kero uye serial yekufambisa chiyero pane yekudzora system hardware nenzira kwayo zvinoenderana neyakapihwa dial switch diagraph musoftware.
5. Tarisa kana jumper cap yakasununguka kana yakavharwa;Kana iyo jumper cap isina kusununguka, ndapota ita shuwa kuti kwakanangana neiyo jumper cap ndeyechokwadi.
6. Kana mushure mekutarisa uye kugadziriswa kwepamusoro, pachine dambudziko pakutakura, tapota shandisa multimeter kuyera kana serial port yekombuta yakabatana kana control system hardware yakakuvadzwa, kusimbisa kana inofanira kudzorerwa kumugadziri wekombiyuta. kana iyo control system hardware yekuyedza.
03 Nei chidzitiro che LED chichiita sechitema zvachose?
Mukuita kwekushandisa kudzora masisitimu, tinombosangana nechiitiko che LED skrini ichiita dema zvachose.Chiitiko chimwe chete chinogona kukonzerwa nezvikonzero zvakasiyana siyana, kunyangwe kuita kwescreen kushanduka dema kunogona kusiyana zvichienderana nemashandiro akasiyana kana nharaunda.Semuenzaniso, inogona kuita dema panguva yekubatidzwa kwemagetsi, inogona kuita dema panguva yekurodha, kana kuita dema mushure mekutumira, zvichingodaro:
1. Ndapota chengetedza kuti hardware yose, kusanganisira hurongwa hwekutonga, inoshandiswa zvakanaka.(+5V, usadzokera kumashure kana kubatanidza zvisizvo)
2. Tarisa uye simbisa kakawanda kana serial cable inoshandiswa kubatanidza mutongi yakasununguka kana kuti yakavharwa.(Kana ikaita dema panguva yekurodha, inogona kunge iri nekuda kwechikonzero ichi, ndiko kuti, inokanganiswa nekuda kwemitsara yekukurukurirana yakasununguka panguva yekutaurirana, saka skrini inoshanduka dema. Usafunga kuti skrini haisi kufamba. , uye mitsetse haigoni kusunungurwa.
3. Tarisa uye simbisa kana bhodhi rekugovera HUB rakabatana ne LED skrini uye kadhi guru rekutonga rakanyatsobatanidzwa uye rinoiswa kumusoro.
04 Chikonzero nei skrini yese yeyuniti bhodhi isina kupenya kana kudzima
1. Ongorora nemaziso matambo emagetsi emagetsi, tambo dzeribhoni dze26P pakati pemabhodhi eyuniti, uye magetsi emodule module yemagetsi kuti uone kana ari kushanda nemazvo.
2. Shandisa multimeter kuyera kana iyo unit board ine yakajairika voltage, uye wobva wayera kana voltage inobuda yemagetsi module yakajairika.Kana zvisina kudaro, zvinotongwa kuti iyo module yemagetsi yakashata.
3. Kuyera yakaderera voltage yemagetsi module uye gadzirisa kugadzirisa kwakanaka (pedyo nechiratidzo chechiedza chemagetsi emagetsi) kuti uwane chiyero chemagetsi.
