Iko kukosha kweGGN mumatunhu
Munguva yePCB ichiriraMaitiro, mainjiniya anotarisana nekurapa kwakasiyana kweGNG.
Nei izvozvo zvichiitika? MuDunhu redunhu Scematic Design Chikamu, kuitira kuderedza kupindirana pakati pematunhu, mainjiniya anowanzo suma madhiri akasiyana eGG
Kuiswa kweGND Ground Wires:
1. Analog Ground Wire Agnd
Analog Ground Wire Agond inonyanya kushandiswa muAnalog Dunhu chikamu, senge adc inowana dunhu reAnalog Sensors, Operation Amplifier Circriit, etc.
Mune aya analog matunhu, nekuti chiratidzo chiratidzo chiratidzo cheAnalog uye chiratidzo chisina kusimba, chinokanganiswa nyore nyore nemafambisirwo makuru emamwe madonhwe. Kana isina kusiyaniswa, mahombe makuru anogadzira hombe madonhwe mudunhu reAnalog, achikonzera chiratidzo cheAnalog kuti chisimbiswe uye chingangoita analog cired dunhu rekukundikana.
2. Digital pasi waya DGND
Digital Ground Wire DgndMicrocontroller Dunhu, nezvimwe.
Chikonzero chekuisa Digital Ground Wire Dgnd ndechekuti Digitive Denders ine chinhu chakajairika, ndechipi chinhambwe switch chiratidzo chakasarudzika pakati pe "0" uye ", sezvakaratidzwa mumufananidzo pazasi.
Munguva yekuita kweiyo voltage ichichinja kubva "0" kusvika "1" kana kubva "1" kusvika "0", iyo vifa inoburitsa shanduko. Maererano neiyo Maxwell Electromagnetic dzidziso, iyo inochinja zvazvino ichagadzira munda wemagireti wakakomberedza, uchigadzira emc radiation pane mamwe matunhu.
Kuti uderedze kukanganiswa kwe emc radiation pamatunhu, gadziriso yedhijitari yedhijitari waya dgnd inofanira kushandiswa kupa kuzviparadzaniswa kunobatsira kune mamwe matunhu ekuparadzanisa.
3. Simba Ground Wire PGNG
Kunyangwe iri analog Ground Wire AGND kana dijitital pasi waya DGNG, ivo vese vari madunhu akaderera-simba. Mumasekinoroji emagetsi akakwirira, senge mota drive dressices, electromagnetic vhezheni yekutakura matunhu, kune zvakare nzvimbo yakaparadzaniswa ivhu waya inonzi Simba Ground WIRE PGNG.
Nzvimbo-Dzemahara Matunhu, sezita rinoratidza, matunhu ane mahombekombe akakura. Zviripachena, mahombekombe makuru anogona kukonzera nyore kukonzera gadziriso pakati pebasa rakasiyanamatunhu.
Pakangosvika pasi pekubvisa mudunhu, iyo yekutanga 5V voltage inogona kunge isiri 5v zvekare, asi iva 4V. Nekuti iyo 5V voltage ihama kune iyo 0V Referenti GNG Ground Wire. Kana iyo pasi yekubvisa inokonzeresa GND kuti isimuke kubva ku0V kusvika ku1V
4. Simba Supply Ground Wire GNG
Analog Ground Wire Agnd, Digital Ground Wire DGNG, uye Simba Ground Wire PGNS All Yese Yese YEMAHARA GND GND. Iyi mhando dzakasiyana dzemazwi epasi dzinofanira kuunganidzwa pamwechete seLIV LEATE LEAIRE yeDunhu rese, inonzi Simba Supply Waire GND GND GND.
Iyo Simba Kuwanikwa iswo simba sosi yematunhu ese. Yese voltage uye zvazvino zvinodiwa kuti itunhu iendeke kubva pane simba rekuwanikwa. Naizvozvo, pasi pevhu waya gnd yekugovera kwemagetsi ndiyo ye1 0V voltage Reference point yezvinhu zvese.
Ndokusaka mamwe marudzi emagetsi emaya, angave analog Ground Wire Agond, Digital Ground Wire Dgnd
5. AC Ground wire cgnd
Iyo AC Ground Wire CGN inowanzo kuwanikwa mumatunhu ane ac simba masosi, senge ac-dc simba magetsi ekuisa masimba matunhu.
AC-DC Magetsi Suppty Dunhu dzakakamurwa kuita zvikamu zviviri. Nhanho yekumberi yedunhu iri iyo Ac redunhu, uye iyo Stage Stage ndeye dcuit dunhu, iyo inomanikidzwa kuumba waya mbiri, imwe ndiyo ika waya ya waya, uye imwe yacho iyo dunhu re dc ivhu.
Iyo AC Ground Wire Inoshanda se 0V Reference Podhi yeiyo AC Dunhu chikamu, uye dc Ground Wire inoshanda seiyo 0V Reference point yeDC CICK CIRCTIC chikamu chikamu. Kazhinji, kuitira kuti ubatise ivhu waya yewaya grundu, mainjiniya anobatanidza iyo AC Ground waya kune iyo dunhu raya neD dc pasi kuburikidza neCoupling Capacitor kana Inductor.
6. Earth Ground Wire Egnd
Iyo yekuchengetedza voltage yemuviri wemunhu iri pazasi 36V. Kana iyo voltage inodarika 36v ichishandiswa kumuviri wemunhu, zvichakuvadza muviri wemunhu. Uku ndiko kuchengetedzeka kwakajairika kune mainjiniya paunenge uchigadzira dunhu redunhu magadzirirwo.
Kuti uwedzere kuchengetedzeka kwechinhu chedunhu, mainjiniya anowanzo shandisa pasi pasi peaya uye mapurogiramu azvino, akadai semidziyo yemumba senge mafoni, mafiriji, uye terevhizheni. Socket ine egnd Dziviriro basa inoratidzwa mumufananidzo pazasi.
Chikonzero nei zvigadziko zveMusamba zveMusamba
Mahwindo maviri aya anoshandiswa kune waya anogara uye asina kwavakarerekera masimba 220V, apo iyo yechitatu terminal inoshanda seyekudzivirira pasi pasi (egnd).
Izvo zvakakosha kuti uzive kuti pasi pasi (egnd) rakabatana pasi pasi uye rinodzivirira kubva pakanyanya kuvhiringidzika. Izvo hazvipindirani mumatunhu edunhu uye hauna kubatana nebasa redunhu.
Naizvozvo, pasi pasi (egnd) rine kukosha kwemagetsi kwakasiyana kubva kune mamwe marudzi epasi (GNG) kubatana.
Kuongorora iyo nheyo yeGND:
Mainjiniya anogona kushamisika kuti sei paine akawanda akasiyana epasi (GNG) kubatana uye nei vachifanira kuunza mabasa mazhinji eGNG.
Kazhinji, mainjiniya akarerutsa zita reGNG vanobatana kuti "GND" pasina kusanganisa mu schematic marobhoti, zvichiita kuti zviome kuona nzvimbo dzakasiyana-siyana mukati mePCB raizi. Nekuda kweizvozvo, zvese zvinobatanidza zvinongedzo zvinongoitika chete.
Kunyangwe iyi yekuvhiya yakareruka iri nyore, inotungamira kumatambudziko ematambudziko:
1. Kukanganisa chiratidzo:
Kana akasiyana mashandiro emagetsi (GND) anobatana zvakanyatsobatanidzwa, masimba masimba ekufambisa nenzvimbo yeiyo 0V
2. Kuratidzira kurongeka:
Kune maAnalog Dunhu, Signal Kukurukurirana kwakakosha metric metric. Kurasikirwa kurongeka kunobatanidza kukosha kwekutanga kwebasa reAnalog.
Iyo pasi (CGN) yeAC Simba Supply Inoshandura mune yenguva pfupi sinusoidal waveform, inokonzeresa voltage yanyura zvakare. Kusiyana neD dc Ground (GNG), iyo inosara nguva dzose pa0V.
Kana dzakasiyana Dunhu Girlo
3. EMCKuyedza:
Iyo isina kusimba chiratidzo, isina kusimba iyo yekunze yemagetsi emagetsi (EMC). Iyo yakasimba chiratidzo, iyo yakasimba iyo yekunze emc.
Kana dzakasiyana Dunhu Ground (GND) kubatana kwakabatana, iyo pasi (GND) yechiratidzo chakasimba chechiratidzo chakanangana nenyika (GND) yechiratidzo chisina kusimba. Nekuda kweizvozvo, iyo yekutanga isina kusimba Electromagnetic radiation (EMC) chiratidzo chinova sosi yakasimba yeElectromagnetic radiation kuenda kunze, ichiita kuti iite kuti iome kunyanyisa kubata EMC kuedza.
4. Kuvimbika Kwematunhu:
Vashoma kubatana pakati pehurongwa hwenzvimbo, yakakura yekuzvimiririra kugona kwedunhu rimwe nerimwe. Zvakare, iyo yakawanda kubatana, iyo isina kusimba iyo yakazvimirira kugona kugona.
Funga nezvezvikamu zvitatu zvematunhu, A uye B, pasina mipendero. Kuita kwedunhu redunhu hakufanirwe kukanganisa mashandiro akajairika ehurongwa hwechitima b, uye zvinopesana.
Izvi zvakafanana neevasingazive vausingazive, uko kushanduka kwemanzwiro emunhu mumwe chete kwaisazokanganisa mamiriro eumwe nekuda kwekuti havana kubatana.
Kana dzakasiyana Dunhu Ground (GND) kubatana mukati mehurongwa hwedenderedzwa, inowedzera chinongedzo chekubatanidza chinowedzera pakati pematunhu, nekudaro vachidzora kuvimbika kwekushanda kwematunhu.
