Zinthu zogwiritsira ntchito mwaukadaulo wazitsulo zodulira magetsi

Mfundo kukhazikitsa luso lazida zamagetsi zamagetsi

Masiku ano, lumo lamagetsi lakhala likugwiritsidwa ntchito kwambiri popanga ndi moyo chifukwa cha zosavuta komanso zopulumutsa ntchito, monga kudulira mitengo yamaluwa, kudulira, kudulira mitengo yazipatso, ntchito yolima dimba, kudulira katundu, ndi kupanga mafakitale. Muzojambula zam'mbuyomu, lumo lamagetsi ndi zida zamagetsi zomwe zimagwiritsidwa ntchito pamanja zomwe zimagwiritsa ntchito galimoto yamagetsi ngati mphamvu ndikuyendetsa mutu wogwira ntchito kudzera mu njira yopatsirana kuti igwire ntchito zometa. Wopangidwa ndi zida zodulira, etc.

Komabe, mukamagwiritsa ntchito lumo lamagetsi, n'zosavuta kuti lumo lichite zinthu zomwe sakufuna kugwiritsa ntchito. Mwachitsanzo, wogwiritsa ntchito amakoka chowombera, koma tsambalo silikutseka, kapena choyambitsa chabwerera koma injiniyo ikuzungulirabe ndipo lumo ukugwirabe ntchito. dikirani. Izi zidzabweretsa zoopsa zachitetezo kwa lumo lamagetsi kapena wogwiritsa ntchito. Zinthu zogwirira ntchito mwaukadaulo: Pangani chowongolera chamagetsi chamagetsi kuphatikiza: unit control unit mcu kulandira ma siginecha ndikupanga malangizo;

Chigawo chodziwikiratu chosinthira chimalumikizidwa ndi MCU ndipo chimakhala ndi sensa yoyamba ya Hall ndi chosinthira choyamba. Chosinthira choyamba chimayikidwa pamalo oyambitsa magetsi amagetsi kuti wogwiritsa ntchito ayambitse mphamvu yamagetsi yamagetsi mu standby state. Sensa yoyamba ya Hall Yolumikizidwa ndi chosinthira choyamba ndikuzindikira kutsegulira ndi kutseka kosinthira koyamba, ndikutumiza chizindikiro choyamba chodziwika ku mcu;

lumo m'mphepete chatsekedwa malo ozindikira dera, lomwe limalumikizidwa ndi mcu ndipo limakhala ndi sensa yachiwiri ya Hall ndi Kusintha kwachiwiri, chosinthira chachiwiri chimayikidwa pamalo otsekedwa a lumo lamagetsi, sensor yachiwiri ya Hall imalumikizidwa ndi chosinthira chachiwiri. imazindikira kutsegulira ndi kutseka kwa chosinthira chachiwiri, ndikutumiza chizindikiro chachiwiri chomwe chapezeka ku mcu;

Scissors Mpeni m'mphepete kutsegulira malo ozindikira dera lolumikizidwa ndi MCU ndipo ili ndi sensor yachitatu ya Hall ndi switch yachitatu. Chosinthira chachitatu chimayikidwa pamphepete mwa mpeni potsegula malo a lumo lamagetsi. Sensa yachitatu ya Hall imalumikizidwa ndi chosinthira chachitatu ndikuzindikira sensor yachitatu ya Hall. Kutsegula ndi kutseka kwa masinthidwe atatu, ndipo chizindikiro chachitatu chodziwika chimatumizidwa ku mcu;

pamene mcu ilandira chizindikiro choyamba chosinthira, ndi mlingo wochepa, ndipo chizindikiro chachiwiri chosinthira kapena chizindikiro chachitatu chosinthira chimakhala pamlingo wapamwamba komanso wotsika. Kawirikawiri, MCU imatsimikizira kuti lumo lamagetsi likugwira ntchito molakwika ndipo limapereka lamulo lokakamiza;

Pamene MCU imalandira kuti chizindikiro choyamba chosinthira ndipamwamba kwambiri ndipo chizindikiro chachiwiri chosinthira kapena chizindikiro chachitatu chosinthira chikupitiriza kukhala chapamwamba kapena chochepa, MCU imatsimikiza kuti lumo lamagetsi likugwira ntchito molakwika ndipo limapereka lamulo lokakamiza.

Kuphatikiza apo, gawo lodziwikiratu losinthira limaphatikizansopo capacitor yoyamba, capacitor yachiwiri, resistor yoyamba ndi resistor yachiwiri. Wotsutsa woyamba ndi wachiwiri wotsutsa amalumikizidwa mndandanda. Mapeto amodzi a capacitor woyamba amalumikizidwa ndi chopinga choyamba, ndipo china chimalumikizidwa ndi nthaka. Mapeto amodzi a ma capacitors awiriwa amalumikizidwa ndi chopinga chachiwiri, ndipo china chimalumikizidwa ndi nthaka.

Makamaka, kukana kwa woyamba resistor r1 ndi 10 kiloohms, kukana kwachiwiri resistor r2 ndi 1 kiloohm, capacitor yoyamba c1 ndi 100nf ceramic capacitor, ndipo capacitor yachiwiri ndi 100nf ceramic capacitor.

Kuphatikiza apo, gawo loyang'ana m'mphepete mwa lumo lotsekera limaphatikizapo capacitor yachitatu, capacitor yachinayi, resistor yachitatu ndi resistor wachinayi. Wotsutsa wachitatu ndi wachinayi wotsutsa amalumikizidwa mndandanda. Mbali imodzi ya capacitor yachitatu imalumikizidwa ndi chopinga chachitatu ndipo mapeto enawo amakhazikika. Mapeto amodzi a capacitor wachinayi amalumikizidwa ndi chopinga chachinayi, ndipo mapeto ena amalumikizidwa ndi nthaka.

Makamaka, kukana kwachitatu resistor r3 ndi 10 kiloohms, kukana kwachinayi resistor r4 ndi 1 kiloohm, chachitatu capacitor c3 ndi 100nf ceramic capacitor, ndipo capacitor wachinayi ndi 100nf ceramic capacitor.

Kupitilira apo, mawonekedwe otsegulira mawonekedwe a lumo amaphatikiza capacitor yachisanu, capacitor yachisanu ndi chimodzi, resistor yachisanu ndi resistor yachisanu ndi chimodzi. Wotsutsa wachisanu ndi wotsutsa wachisanu ndi chimodzi amalumikizidwa mndandanda. Mapeto amodzi a capacitor wachisanu amalumikizidwa ndi chopinga chachisanu ndipo mapeto ena amakhazikika. , mbali imodzi ya capacitor yachisanu ndi chimodzi imagwirizanitsidwa ndi resistor yachisanu ndi chimodzi, ndipo mapeto ena amagwirizanitsidwa ndi nthaka.

Makamaka, kukana kwa 5 resistor r5 ndi 10 kiloohms, kukana kwachisanu ndi chimodzi resistor r6 ndi 1 kiloohm, capacitor yachisanu c5 ndi 100nf ceramic capacitor, ndipo capacitor yachisanu ndi chimodzi ndi 100nf ceramic capacitor.

Kukhazikitsidwa kwa dera lamagetsi lamagetsi lamagetsi lomwe lapangidwako lili ndi zotsatirazi zopindulitsa: dera lililonse lodziwikiratu la dera lamagetsi lamagetsi lili ndi sensa yofananira ya Hall, ndipo sensor ya Hall imatha kutulutsa zofananira zofananira zakusintha kofananira ndi kutsegula ndi kutseka malo a lumo. Chizindikiro chimaperekedwa kwa MCU, ndipo MCU imatha kuwongolera kuzungulira kwa injini ndi machitidwe a scissor blade malinga ndi zizindikiro zofananira za kusintha kwa kusintha ndi kutsegula ndi kutseka kwa scissor blade. Pamene lumo lamagetsi lili pamalo oyambitsa ndikukokedwa, scissor blade imakhala yokhazikika ndipo choyambitsa sichili Pamene lumo likukokedwa koma likugwira ntchito, MCU imazindikira kuti sirasi yamagetsi ikugwira ntchito molakwika ndikupereka mokakamiza. mphamvu-kuzimitsa lamulo. Cholinga chake ndi kuchepetsa kusuntha kwachilendo kwa lumo lamagetsi ndikupereka chitetezo kwa lumo lamagetsi ndi ogwiritsa ntchito.
