Cc-smart technology CCS-SHB45A Smart H-Bridge

Kampaniyi ili ku 1419/125 Le Van Luong, Phuoc Kien Commune, Nha Be District, Ho Chi Minh City, Vietnam. Atha kulumikizidwa kudzera pa foni pa +84983029530 kapena kudzera pa imelo ccsmart.net@gmail.com. Zambiri za kampaniyo zitha kupezeka patsamba lawo webWebusayiti yathu pa www.cc-smart.net. Buku logwiritsa ntchitoli limapereka chidziwitso choyambira, mawonekedwe, ntchito, lamulo la UART, ndi kasinthidwe. Chogulitsacho ndi Dalaivala wamkulu wa H-Bridge wopangidwa kuti aziwongolera mota yayikulu ya DC yomwe ili ndi liwiro komanso kolowera. Galimoto imayendetsedwa ndi MOSFETs ndi 16 KHz kusinthana kuti igwire bwino ntchito komanso phokoso lochepa.
Dalaivala amathandizira mawonekedwe a Acceleration / Deceleration omwe amathandiza kuteteza zida zamagetsi ndi makina a dongosolo. Zimaphatikizansopo Magetsi Awiri Amakono Apanyumba kuti achepetse kusuntha kumanzere ndi kumanja, kuchotsa kufunikira kosinthira malire owonjezera. Dalaivala amayang'anitsitsa momwe galimoto ilili panopa ndikuyika Mbendera Yokhudzidwa kuti asiye kuyenda kumalo enaake ngati mphamvuyo idutsa iLimit (malire apano omwe amaikidwa ndi potentiometer pa PCB). Kuti muyambitsenso kuyenda, dalaivala amayenera kuwongolera mbali yakumbuyo kapena Touched Flag iyenera kuchotsedwa.
Kuphatikiza apo, dalaivala amapereka chitetezo ku Under voltage, Kupitilira voltage, Kutentha Kwambiri, ndi Kupitilira Panopa. Imathandizira njira zosiyanasiyana zoyankhulirana monga PWM/Dir, PWM Bi-direction, Analog/Dir, Analog Bi-Direction, Uart Network, ndi PPM Independent sign (RC). Njira yolankhulirana imatha kusankhidwa mosavuta pogwiritsa ntchito Dip Switch pa PCB.

6. Onetsetsani kuti dalaivala walumikizidwa bwino ndipo zolumikizira zonse zili zotetezeka.
7. Ikani mphamvu pamakina ndikuwongolera liwiro la mota ndi njira yolumikizirana yosankhidwa.
8. Yang'anirani mphamvu ya injini ndikusintha iLimit potentiometer pa PCB ngati kuli kofunikira.
9. Ngati mphamvu ya injini ipitilira iLimit yomwe idayikidwa, dalaivala amakhazikitsa Touched Flag ndikuyimitsa kuyenda komweko. Chotsani Mbendera Yokhudza kapena kuwongolera mota mobwerera chakumbuyo kuti muyambirenso kuyenda.
10. Yang'anirani mawonekedwe achitetezo a dalaivala monga Under voltage, Kupitilira voltage, Kutentha kwapamwamba, ndi Kupitilira Pakalipano kuonetsetsa chitetezo cha dongosolo.

Zindikirani: Kuti mudziwe zambiri zamakina ndi zambiri zamalo ogwirira ntchito, onani buku lathunthu la ogwiritsa ntchito.

Mawu Oyamba

Dalaivala ndi wamkulu wanzeru H-Bridge Driver yomwe idapangidwa kuti iziwongolera mota yayikulu kwambiri ya DC yokhudzana ndi liwiro ndi komwe akupita. The Motor imayang'aniridwa ndi MOSFETs ndi 16 Khz kusinthana ndikuchita bwino komanso phokoso.
Dalaivala amathandizira mawonekedwe a Acceleration / Deceleration. Izi zithandizira kuteteza Magetsi, Makina…Zidzakhala zothandiza pamapulogalamu ambiri.
Dalaivala amathandiziranso Sensor Yamagetsi Yamakono Yamakono mkati kuti achepetse kumanzere ndi kumanja. Wogwiritsa safunikira kusintha kowonjezera kwa malire. Dalaivala uyu adzayang'anira zamakono pamene Motor ikuthamanga, ngati panopa ya Motor ikufanana ndi iLimit
(iLimit ndi malire apano okhazikitsidwa ndi potentiometer mu PCB), dalaivala adzakhazikitsa Mbendera Yokhudza ndikusiya kusuntha komweko. Kuti musunthe, dalaivala amafunikira kuwongolera ndi njira yakumbuyo kapena Touched Flag iyenera kumveka bwino.
Dalaivala amathandizira njira zambiri zotetezera monga Under voltage, Kupitilira voltage, Kutentha kwambiri, Kupitilira Panopa. Zodzitetezera izi ndizofunikira kwambiri mfiti zothandizira kusunga chitetezo.
Chapadera, The Smart H-bridge imathandizira njira zonse zolumikizirana zofala.
Wogwiritsa ndi wosavuta kusankha njirayo ndi Dip Switch mu Pcb:

Kusintha

Kusintha kwa mtundu wolowetsa:
Dalaivala amathandizira mitundu yambiri ya njira zoyankhulirana monga PWM/DIR, PPM, UARTs, …Imaphatikiza Pini yolowera kuti muchepetse kulumikizana. Dalaivala amagwiritsa ntchito batani la CONF kuti asinthe mtundu wa kulumikizana komwe mukufuna. Chonde konzani njira yolumikizirana musanagwiritse ntchito.
Kukhazikitsa processing:

• Dinani ndi Gwirani batani la CONF kuposa ma 5s kuti mulowe mu Config mode. (The Led_iOVER, Led_ERR, Led_Run idzaphethira, Chiwerengero cha kuphethira ndi ntchito ya nambala)
• Dinani N nthawi kuti musankhe Function N. (The Led_iOVER, Led_ERR, Led_Run idzaphethira N nthawi kusonyeza ntchito N ikusankha.
• Dinani ndi Gwirani batani la CONF kuposa ma 5s kachiwiri kuti musunge ndikutuluka mumayendedwe.

Langizo:

• config parameter idzasungidwa ku Flash ndikugwiritsidwa ntchito pambuyo pake
• Pamene mphamvu kapena kusintha mode. Led_Run idzawombera nambala yotsatizana ya N kusonyeza kuti mfiti zakonzedwa.

Chitetezo ndi Chizindikiro:

Chitetezo:

• Pansi / Pamwamba pa Voltage (vBus):
  Kutulutsa kwa dalaivala wamoto kudzatsekedwa pamene mphamvu yowonjezera voltage amatsika pansi pa malire apansi. Izi ndikuwonetsetsa kuti ma MOSFET ali ndi voliyumu yokwaniratage kuti muyatse kwathunthu ndipo musatenthedwe. ERR LED idzawunikira mkati mwa voltagndi shutdown.
• Chitetezo cha Kutentha:
  The pazipita panopa malire malire amatsimikiziridwa ndi bolodi kutentha. Kukwera kwa kutentha kwa bolodi, kumachepetsa malire apano. Mwanjira iyi, dalaivala amatha kupereka mphamvu zake zonse malinga ndi momwe zilili zenizeni popanda kuwononga ma MOSFET.
• Chitetezo cha Overcurrent ndi Active Current Limiting
  Pamene galimoto ikuyesera kukoka zamakono kuposa zomwe woyendetsa galimoto angapereke, PWM ku galimotoyo idzadulidwa ndipo injini yamakono idzasungidwa pamlingo wapamwamba kwambiri. Izi zimalepheretsa dalaivala wagalimoto kuti asawonongeke pomwe mota imayimilira kapena mota yokulirapo yalumikizidwa. OC LED idzayatsidwa pamene malire akugwira ntchito.

System Grounding
Kuchita bwino kwapansi kumathandizira kuchepetsa phokoso lalikulu lomwe limapezeka mudongosolo. Zifukwa zonse zomwe zili mkati mwadongosolo lodzipatula ziyenera kumangirizidwa ku PE (dziko lapansi loteteza) kudzera pa 'SINGLE' yotsika kukana. Kupewa maulalo obwerezabwereza ku PE kupanga malupu apansi, omwe amakhala magwero a phokoso pafupipafupi. Pansi pa mfundo yapakati iyeneranso kugwiritsidwa ntchito poteteza chingwe; zishango ziyenera kukhala zotseguka mbali imodzi ndikukhazikika mbali inayo. Chisamaliro chambiri chiyeneranso kuperekedwa kwa mawaya a chassis. Za example, ma motors nthawi zambiri amaperekedwa ndi waya wa chassis. Ngati waya wa chassis walumikizidwa ndi PE, koma chiwongolero chamotocho chimalumikizidwa ndi chimango cha makina, chomwe chimalumikizidwanso ndi PE, kuzungulira kwapansi kudzapangidwa. Mawaya omwe amagwiritsidwa ntchito poyatsira pansi ayenera kukhala olemera kwambiri komanso aafupi momwe angathere. Mawaya osagwiritsidwa ntchito ayeneranso kukhazikitsidwa ngati ali otetezeka chifukwa mawaya omwe amasiyidwa akuyandama amatha kukhala ngati tinyanga zazikulu, zomwe zimapangitsa kuti EMI.
Kulumikizana Kwamagetsi 
OSATI kulumikiza mphamvu ndi nthaka molakwika, chifukwa zingawononge dalaivala. Mtunda pakati pa magetsi a DC oyendetsa galimoto ndi galimoto yokhayo iyenera kukhala yaifupi momwe mungathere chifukwa chingwe pakati pa awiriwa ndi gwero la phokoso. Pamene mizere yoperekera mphamvu ikupitirira 50 cm, 1000µF/100V electrolytic capacitor iyenera kulumikizidwa pakati pa terminal "GND" ndi terminal "+VDC". Capacitor iyi imakhazikika voltage amaperekedwa kwa galimotoyo komanso zosefera phokoso pa chingwe chamagetsi. Chonde dziwani kuti polarity siyingasinthidwe.
Ndikoyenera kukhala ndi madalaivala angapo kuti agawane mphamvu imodzi kuti achepetse mtengo ngati katunduyo ali ndi mphamvu zokwanira. Kuti mupewe kusokonezedwa, MUSAMAGWIRITSE NTCHITO ma pin olowetsa magetsi a madalaivala. M'malo mwake, chonde alumikizeni kumagetsi padera.
