Unyanzvi hwekuita zvinhu zvemagetsi ekuchekerera zvigero

Mazuva ano, zvigero zvemagetsi zvave zvichishandiswa zvakanyanya mukugadzira uye hupenyu nekuda kwekureruka uye nekuchengetedza vashandi, sekuchekerera miti yebindu, kuchekerera, kuchekerera miti yemichero, basa rekurima, kurongedza zvigadzirwa, uye kugadzirwa kwemaindasitiri. Muunyanzvi hwepamberi, zvigero zvemagetsi zvigetsi zvemagetsi zvakabatwa nemaoko zvinoshandisa mota yemagetsi sesimba uye kutyaira musoro unoshanda kuburikidza nemuchina wekufambisa kuita mabasa ekuveura. Inoumbwa nemidziyo yekucheka, nezvimwe.

Zvisinei, kana uchishandisa chigero chemagetsi, zviri nyore kuti chigero chiite zviito zvisina kurongwa nemushandisi. Semuenzaniso, mushandisi anodhonza tambo, asi blade haivharike, kana tambo yadzoka asi mota ichiri kutenderera uye chigero chichiri kushanda. wait. Izvi zvinounza njodzi dzekuchengetedza kune chigero chemagetsi kana mushandisi. Tekinoroji yekushandisa zvinhu: Gadzira yemagetsi scissors control circuit inosanganisira: yepakati control unit mcu kugamuchira masaini uye kuita mirairo;

Iyo switch inokonzeresa yekuona yedunhu yakabatana neMCU uye ine yekutanga Hall sensor uye yekutanga switch. Shanduko yekutanga inoiswa panzvimbo inokonzeresa yechigero chemagetsi kuti mushandisi akonzerese kuita kwemota yechigero chemagetsi munzvimbo yekumira. Yekutanga Hall sensor Yakabatanidzwa kune yekutanga switch uye kuona kuvhura nekuvhara mamiriro ekutanga switch, uye kutumira iyo yakaonekwa yekutanga switch chiratidzo kune mcu;

scissors edge yakavharwa nzvimbo yekuona dunhu, iyo yakabatana nemcu uye ine yechipiri Hall sensor uye yechipiri Shandura, yechipiri switch inoiswa munzvimbo yakavharwa yechigero chemagetsi, yechipiri Hall sensor yakabatana kune yechipiri switch uye inoona nzvimbo yekuvhura uye yekuvhara yechipiri switch, uye inotumira yakaonekwa yechipiri switch chiratidzo kune mcu;

Scissors Iyo banga kumucheto kuvhura nzvimbo yekuona wedunhu yakabatana neMCU uye ine yechitatu Hall sensor uye yechitatu switch. Iyo yechitatu switch inoiswa panzvimbo yebanga kumucheto kuvhurwa kwechigero chemagetsi. Yechitatu Hall sensor yakabatana neyechitatu switch uye inoona yechitatu Hall sensor. Iyo yekuvhura uye yekuvhara mamiriro eiyo switch matatu, uye yakaonekwa yechitatu switch chiratidzo inotumirwa kune mcu;

kana iyo mcu inogamuchira yekutanga switch chiratidzo, yakaderera mwero, uye yechipiri chinja chiratidzo kana chechitatu chekuchinja chiratidzo chiri pamwero wepamusoro uye wakaderera. Kazhinji, iyo MCU inosarudza kuti chigero chemagetsi chiri kushanda zvisina kujairika uye chinopa murairo wekumanikidzira wemagetsi;

Kana iyo MCU ikagamuchira kuti yekutanga switch siginecha yakakwira uye yechipiri chinja chiratidzo kana yechitatu chinja chiratidzo inoramba ichikwira kana yakaderera nhanho, iyo MCU inoona kuti chigero chemagetsi chiri kushanda zvisina kujairika uye chinopa kumanikidzwa kudzima murairo.

Kupfuurirazve, iyo switch inokonzeresa yekuona yedunhu inosanganisira yekutanga capacitor, yechipiri capacitor, yekutanga resistor uye yechipiri resistor. Yekutanga resistor uye yechipiri resistor yakabatana munhevedzano. Imwe magumo ekutanga capacitor yakabatana kune yekutanga resistor, uye imwe magumo yakabatana pasi. Imwe mugumo weaviri capacitors yakabatana kune yechipiri resistor, uye imwe mugumo yakabatana pasi.

Zviri nani, kuramba kwekutanga resistor r1 i10 kiloohms, kuramba kwechipiri resistor r2 ndeye 1 kiloohm, yekutanga capacitor c1 ndeye 100nf ceramic capacitor, uye yechipiri capacitor ndeye 100nf ceramic capacitor.

Uyezve, chigero chekuvhara nzvimbo yekuona nzvimbo yekuona inosanganisira yechitatu capacitor, yechina capacitor, yechitatu resistor uye yechina resistor. Yechitatu resistor uye yechina resistor yakabatana munhevedzano. Imwe magumo echitatu capacitor yakabatana kune yechitatu resistor uye imwe mugumo yakadzikwa. Imwe magumo echina capacitor yakabatanidzwa kune yechina resistor, uye imwe mugumo yakabatanidzwa pasi.

Zviri nani, kuramba kwechitatu resistor r3 i10 kiloohms, kuramba kwechina resistor r4 i1 kiloohm, yechitatu capacitor c3 ndeye 100nf ceramic capacitor, uye yechina capacitor i100nf ceramic capacitor.

Kupfuurirazve, chigero chekuvhura chinzvimbo chekutarisa chinosanganisira yechishanu capacitor, yechitanhatu capacitor, yechishanu resistor uye yechitanhatu resistor. Yechishanu resistor uye yechitanhatu resistor yakabatana munhevedzano. Imwe magumo echishanu capacitor yakabatana kune yechishanu resistor uye imwe magumo yakadzikwa. , imwe mugumo wechitanhatu capacitor yakabatanidzwa kune yechitanhatu resistor, uye imwe mugumo yakabatanidzwa pasi.

Zviri nani, kuramba kwechishanu resistor r5 i10 kiloohms, kuramba kwechitanhatu resistor r6 i1 kiloohm, yechishanu capacitor c5 ndeye 100nf ceramic capacitor, uye yechitanhatu capacitor i100nf ceramic capacitor.

Kuitwa kwechigero chemagetsi chekutonga chechigadzirwa chiripo chine zvinotevera zvinobatsira: dunhu rega rega rekuona remagetsi scissors control redunhu rine inoenderana Hall sensor, uye iyo Hall sensor inogona kuburitsa inoenderana inofananidzira yeino chinja chiito uye kuvhura uye nzvimbo yekuvhara yechigero. Chiratidzo chinopihwa kuMCU, uye iyo MCU inokwanisa kudzora kutenderera kwemota uye kuita kwechikasi blade zvinoenderana neanoenderana analogi masaini echiito chekuchinja uye kuvhura nekuvhara chinzvimbo chechikasi. Kana chigero chemagetsi chiri munzvimbo yekufambisa uye chichidhonzwa, chigero chinenge chakamira uye chinokonzeresa hachisi Kana chigero chadhonzwa asi chiri mumamiriro ekushanda, iyo MCU inoona kuti chigero chemagetsi chiri kushanda zvisina kunaka uye chinopa kumanikidzwa. power-off command. Chinangwa ndechekudzikisira mafambiro asina kujairika echigero chemagetsi uye kupa dziviriro yechigero chemagetsi nevashandisi.
