Ntchito yodzitchinjiriza ndikuletsa kutulutsa kopitilira muyeso kwa chubu chamagetsi ndi magetsi owongolera, ndipo okalamba akamayendetsa njinga zamagalimoto okalamba akugwira ntchito, dera lizitenga molingana ndi chizindikiro cha mayankho pakakhala zolakwika kapena zolakwika zomwe zingachitike. kuwononga ndi zolakwika zina.Chitetezo.Ntchito zoyambira zotetezera ndi ntchito zowonjezera zamagalimoto amagetsi kwa okalamba ndi awa:
1. Chotsani mphamvu
Zogwirizira ziwiri za caliper brake pa chogwirizira cha tricycle yopumula kwa okalamba onse ali ndi masiwichi olumikizirana.Pamene braking, chosinthira chimakankhidwa ndikutsekedwa kapena kuchotsedwa, motero kusintha kosinthira koyambirira.Kusinthaku kumapanga chizindikiro ndikutumiza kudera lowongolera, ndipo dera limapereka malangizo molingana ndi pulogalamu yokhazikitsidwa kuti nthawi yomweyo adule ma drive pano, kudula mphamvu, ndikusiya kupereka mphamvu.Choncho, sikuti amangoteteza chubu lamagetsi palokha, komanso amateteza galimoto yakale, komanso amalepheretsa kutaya mphamvu.
2. Chitetezo chopanda mphamvu
Izi zikutanthauza mphamvu yamagetsi yamagetsi.Pa gawo lomaliza la kutulutsa, pansi pa katundu, mphamvu yamagetsi imakhala pafupi ndi "voltage yotsiriza-yotulutsa", ndipo gulu lowongolera (kapena gulu lowonetsera zida) liwonetsa kuti batri silikwanira, zomwe zidzakopa chidwi. wa wokwera ndi kukonzekera ulendo wake.Mphamvu yamagetsi ikafika kumapeto kwa kutulutsa, voliyumu sampling resistor imadyetsa chidziwitso cha shunt kwa comparator, ndipo dera lodzitchinjiriza lidzapereka malangizo molingana ndi pulogalamu yokhazikitsidwa kuti adutse zomwe zilipo kuti ateteze zida zamagetsi ndi magetsi.
3. Chitetezo chopitilira
Kupyola malire omwe alipo kungayambitse kuwonongeka kwa zigawo zingapo za galimoto ndi dera, kapena ngakhale kutentha, zomwe ziyenera kupewedwa.Mu dera lolamulira, mtundu uwu wa chitetezo cha overcurrent uyenera kuperekedwa, ndipo zamakono zidzadulidwa pambuyo pa kuchedwa kwina pamene overcurrent ikuchitika.
4. Chitetezo chochulukirachulukira
Kutetezedwa kochulukirako kumakhala kofanana ndi kutetezedwa kopitilira muyeso, ndipo katundu wopitilira malirewo mosakayikira amachititsa kuti panopo ipitirire malire.Kuchuluka kwa katundu kumasonyezedwa m'mabuku a magalimoto amagetsi, koma okwera ena salabadira mfundoyi, kapena amadzaza mwadala ndi malingaliro oyesera.Ngati palibe chitetezo choterechi, sichingawononge ulalo uliwonse, koma chubu chosinthira mphamvu ndichoyamba kunyamula.Malingana ngati imodzi mwa machubu amagetsi a brushless controller itenthedwa, idzakhala mphamvu ya magawo awiri, ndipo galimoto yakale imakhala yofooka ikathamanga.Wapaulendo amatha kumva kugunda kwachilendo;ngati apitiriza kukwera, ndiye kuti machubu amphamvu achiwiri ndi achitatu adzawotchedwa.Ngati chubu chamagetsi cha magawo awiri sichigwira ntchito, galimotoyo imasiya kuthamanga, ndipo galimoto ya brush imataya ntchito yake yolamulira.Choncho, overcurrent chifukwa chochulukirachulukira ndi owopsa kwambiri.Koma bola ngati pali chitetezo chamakono, dera limangodula magetsi pambuyo pa katundu woposa malire, ndipo zotsatira zambiri zomwe zimadza chifukwa cha kuchulukana zingathe kupewedwa.
5. Chitetezo chochepa kwambiri
Ikadali m'gulu la chitetezo cha overcurrent, ndipo imayikidwa pa brushless control system popanda ntchito yoyambira pa liwiro la 0.
6. Kuteteza malire a liwiro
Ndi pulogalamu yapadera yowongolera kamangidwe ka njinga zamagetsi zothandizidwa ndi okalamba.Liwiro lagalimoto likadutsa mtengo wodziwikiratu, dera limasiya kupereka mphamvu ndipo silipereka thandizo.Kwa magalimoto amagetsi amagetsi kwa okalamba, liwiro logwirizana ndi 20km / h, ndipo liwiro lovomerezeka ndi kayendetsedwe ka kayendetsedwe kake kakhazikitsidwa kale pamene galimoto yagalimoto imapangidwira.Magalimoto okalamba amagetsi amatha kuthamanga pa liwiro losapitilira liwiro ili.Malo a woyang'anira samakhudza ntchito, makamaka zimadalira cholinga cha wopanga.Koma pali mfundo zingapo: (1) Opaleshoni ikaloledwa;(2) Pamene masanjidwe onse amaloledwa;(3) Pamene dongosolo la mzere likufunika;(4) Pamene zipangizo zothandizira zikufunika.
Chizindikiro chowongolera liwiro ndi siginecha yamagetsi, ndipo mphamvu yotulutsa ya Hall turntable imadalira mphamvu ya maginito mozungulira chinthu cha Hall.Kutembenuza chogwirira kumasintha mphamvu ya maginito mozungulira chinthu cha Hall, chomwe chimasinthanso mphamvu ya chogwirira cha Hall.Kenako lowetsani mphamvuyi mu chowongolera, ndipo wowongolera amachita PWM pulse wide modulation malinga ndi kukula kwa chizindikirochi.Choncho, chiŵerengero cha pa-off pa chubu champhamvu chimayendetsedwa kuti chiwongolere liwiro la galimoto.
