一, kugona kweiyo LED Displad Circumed Board yakakuvadzwa
Iko kutadza kunokonzerwa nekukuvara kwecacititor ndiyo yepamusoro mumidziyo yemagetsi, kunyanya kukuvara kweacthitorly capacitor. Canacititit yekutadza inoratidzwa se: 1. Kuderedza simba; 2. Kurasikirwa kwakazara kwekuwanda; 3. Kubhururuka; 4. Pfupi redunhu.
二, kudzivisa kukuvara
Zvakajairika kuona vazhinji vatanga kuenda nevaridzi vevarwi paunenge uchigadzirisa mabhodhi ematunhu, kungave kushungurudzika kana kutengesa. Muchokwadi, nezvimwe zvekugadzirisa, chero bedzi iwe uchinzwisisa hunhu hwekukuvadza hwevarwi, haufanire kunetseka zvakanyanya. Kupesana ndicho chinhu chakawanda kwazvo mumidziyo yemagetsi, asi hachisi chinhu chine huwandu hwakanyanya hwekukuvadza. Kudzivirira kukuvara kunonyanya kujairika mumatunhu akavhurika, nekuwedzera kuramba tsika dzisingawanzo uye kuderedza kudzivisa tsika kushoma. Mhando dzakajairika dzinosanganisira kabhoni firimu resvosari, metal firimu resters, waya ronda raunoronda, uye fuse resters. Isu tinogona kutanga tarisisa kana paine zviratidzo zvezvipenga zvinopfuta pakurwisa kupesana kuramba pane redunhu board. Zvichienderana nehunhu hwezvinhu zvakavhurika zvakanyanya kana kuramba kwakakuvadzwa kana kupokana kwakakanganisika, isu tikajaira kuti tirambe takanyatso kupokana tsika dzekurwisa kumigumo yakakwirira kurwisa pakatarisana nedunhu redunhu. Kana kukosha kwakayerwa kukoshesa kwakakura kupfuura kukosha kwekudzivisa kukosha, kana kuramba kuchinge kwakakuvadzwa kusvika pakukoshesa kusati kwatanga, sezvo kukosha kwekuparadza kwechiitiko. Nenzira iyi, kupokana kwese padunhu redunhu kunoyerwa kamwechete, uye kunyangwe kana ukauraya chiuru, haungapotsa basa rimwe chete.
三, nzira yekutonga mhando yeashanda mashlifiers
Amplifiers ane hunhu hwe "chaiyo pfupi" uye "virtual break", iyo inobatsira kuongorora mutsara wekushanda mashandiro emitambo. Kuve nechokwadi chekunyora chikumbiro, iyo yekushandisa amplifier inofanira kushanda mune yakavharwa loop (isina mhinduro mhinduro). Kana pasina mhinduro dzisina kunaka, iyo yekushanda inoshandisika pasi peViye-loop kuwedzera kwekutora. Kana iwe uchida kutonga mhando yechishandiso, iwe unofanirwa kutanga kusiyanisa kuti mudziyo wacho unoshandiswa seasplifier kana aenzanisa mudunhu. Sekureva kweiyo ongple yeAmplifier pfupi pfupi, ndiko kuti, kana iyo Operlifier inoshanda nemazvo, iyo yekuvhiringidza yekuisa uye kana paine mutsauko, ichiri padanho reMV. Ehezve, mune mamwe magadzirirwo emamwe asina kukodzera, kupokana kwemukati kweiyo multimeter kunogona kuve nekukanganiswa zvishoma pakuongororwa kweVoltage, asi kazhinji hazvipfuure 0.2V. Kana paine mutsauko we 0.5V kana anopfuura, iyo amplifier ichangopera! Kana iyo mudziyo ikashandiswa seye pamuchinjori, inobvumidzwa kuve neyakaenzana yekuisa magetsi mune imwecheteyo nhungamiro uye dzosera mirayiridzo. Kana iyo imwechete voltage yakakura kupfuura reverse voltage, iyo yekuburitsa voltage iri padyo nehukuru hwakanakisa; Kana iyo imwechete voltage
四, chipikiri chekuyedza smt zvikamu zvine multimeter
Zvimwe zvikamu zveSMD idiki kwazvo, zvichiita kuti zviite zvisina kukodzera kushandisa zvakajairika multimeter probes yekuedza nekugadzirisa. Chekutanga, vanogona kukonzera nzvimbo pfupi pfupi, izvo zvinoregedzera mapuranga ematunhu akavezwa nekubatanidzwa kuti asangane nezvikamu zvesimbi zvezvikamu zvemhando. Heino nzira yakapusa iyo ichaunza zvakawanda nyore nyore kuti uedze. Tora maviri ezvisungo zvidiki zvekusona, (zvakadzika zvinyorwa zvekugadzirisa tekinoroji tekinoroji) uye uvaise zvakasimba peni yerudzi rwemuguta. Wobva watora waya yakatetepa yemhangura kubva kune akawanda-tambo Nenzira iyi, kana kuyera zvikamu zveStylus neine diki redhipiti, hapana njodzi yematunhu mipfupi, uye tip yetsika inogona kupinza insolises coatlation uye yakananga zvikamu zvakakosha
五, nzira yekugadzirisa ye pfupi circuit mhosva yedunhu rekirabhu yakajairika simba
MuDunhu redunhu rekuchengetedza, kana paine dunhu pfupi kusvika kune chimwe chinhumagetsi, Kazhinji kakawanda mhosva, nekuti midziyo mizhinji inogovana iyo Simba Simba, uye mudziyo wega wega uchishandisa inopisa yemagetsi inofungidzirwa kuti ipfupi wedunhu. Kana pasina zvakawanda zvikamu mubhodhi, uchishandisa "hoe pasi repasi" nzira inogona pakupedzisira tsvaga pfupi pfupi redunhu. Kana paine zvimwe zvakawanda zvakanyanyisa, kana "iyo" hoe pasi "inogona kuvhara mamiriro ezvinhu zvinoenderana nerombo. Heino nzira inokurudzirwa inoshanda nemazvo. Nekushandisa nzira iyi, iwe unogona kuwana kaviri mhedzisiro nehafu yekuedza uye kazhinji inokurumidza kuwana iyo nzvimbo yekukanganisa. Panofanirwa kuve nekuwanikwa kwemagetsi neanogadziriswa voltage uye ikozvino, neyakahwanda ye 0-30V uye ikozvino ye 02a. Iyi yekupa simba haina kudhura uye inodhura yakakomberedza 300 yuan. Gadzirisa iyo yakavhurika wedunhu voltage kune iyo nhanho yeiyo mudziyomagetsivoltage. Kutanga, gadzirisa zvazvino kusvika zvishoma. Nyorera iyi voltage kune iyo Simba Kugovera voltage mapoinzi edunhu, senge 5v zviyero zve74 series chip. Zvichienderana neiyo degree repfupi redunhu, zvishoma nezvishoma kuwedzera zvazvino. Bata mudziyo neruoko rwako. Kana chimwe chinhu chishandiso chakatsikwa zvakanyanya, kazhinji chinowanzo fundisa chinhu chakakanganisika. Iwe unogona kuibvisa kuti uwedzere kuyerwa uye kusimbiswa. Ehe, iyo voltage panguva yekushanda haifanirwe kupfuura iyo inoshanda voltage yechishandiso, uye hazvifanirwe kudzoserwa, neimwe nzira ichapisa zvimwe zvishandiso zvakanaka.
六, chidiki chidiki kugadzirisa matambudziko makuru
Huwandu hwemapuranga anoshandiswa mukudzora kwemaindasitiri kuri kuwedzera, uye mabhodhi mazhinji anoshandisa nzira yekuisa zvigunwe zvegoridhe mu slots. Nekuda kwenzvimbo yeshiri yehurombo, iyo ine guruva, yakanyorova, uye inokanganisa, zviri nyore kuti mapuranga ave asina kunaka kubata zvikanganiso. Shamwari dzakawanda dzinogona kunge dzakagadzirisa dambudziko nekutsiva mapuranga, asi mutengo wekutenga mabhodhi anofungidzirwa zvakanyanya, kunyanya kune mamwe mabhodhi ekunze anotumirwa kunze. Muchokwadi, munhu wese anogona kushandisa eraser kuti arambe akapukuta tsvina pagungano yendarama kashoma, kuchenesa, oedza muchina zvakare. Zvichida dambudziko richazadziswa! Nzira yacho iri nyore uye inoshanda.
七, kuongororwa kwezvekutadza kwemagetsi nezvakanaka uye zvakashata nguva
Panyaya yekugona, zvikanganiso zvakasiyana zvemagetsi nezvakanaka nezvakaipa zvinogona kusanganisira mamiriro ezvinhu anotevera:
1. Kubata zvisina kunaka pakati pebhodi uye slot, kutadza kubatanidza kana tambo yaputswa mukati, kusatarisana neyakafa, uye kutengeserana kwezvinhu zvese ndezveboka iri;
2. Zvemitambo yedhijitari, malfunctions zvinongoitika pasi pemamiriro ezvinhu nekuda kwekuvhiringidza chiratidzo. Izvo zvinokwanisika kuti kupindira kwakanyanyisa kwakanganisa hurongwa hwekudzora uye kwakaita kuti izvi zvikanganiso, uye zvinokonzeresa perimita yedunhu
3. Murombo anodzora kugadzikana kwezvinhu zvakakura zvehuwandu hwekugadzirisa maitiro, kutarisisa kwekutanga electrolytic capacitor, inoteverwa nedzimwe capacitors, triodes, diodes, Diodes, Dics, resistors, nezvimwewo, nezvimwewo, nezvimwewo, nezvimwewo, nezvimwewo, nezvimwewo, nezvimwewo, nezvimwewo, nezvimwewo, nezvimwewo, nezvimwewo, nezvimwewo, nezvimwewo, nezvimwe, nezvimwe.
4. Kune kunyorova, guruva rekuunganidza, nezvimwe padunhu redunhu. Unyoro neguruva zvichaitisa magetsi nekupokana simba, uye kukosha kwekupokana kuchachinja panguva yekuwedzera kwekuwedzera. Iyi kukosha kwekudzivisa ine yakaenzana mhedzisiro ine zvimwe zvikamu. Kana mhedzisiro iyi yakasimba, paramende yedunhu ichachinjwa, ichikonzera kutadza;
5. Software ndeimwe yezvinhu zvekufunga nezvazvo. Mazhinji paramita ari mudunhu anogadziridzwa uchishandisa software, uye iyo maratidziro emamwe ma paramita akaiswa zvakanyanya, ayo ari mukati meiyo yakaoma huwandu. Kana mamiriro emushini anoshanda anosangana nechikonzero che software yacho kuti azive mhosva, alarm ichaonekwa.
