Ma servos amtundu ndi abwino kwa mapulogalamu ena osati momwe amafunira, monga kuyendetsa bawuti loko. Pakugwiritsa ntchito kosagwirizana, vuto lalikulu ndi "kukakamiza" servo kuti igwire ntchito, chifukwa imafunikira kupatsa mphamvu mawonekedwe a wave ndi magawo ena. Dera lomwe tafotokozali likutichotsera vuto lotere.
Makhalidwe
- Hiten muyezo servo cholumikizira
- kulowetsa kwa ulamuliro wa mayiko awiri
- potentiometers awiri kuti mudziwe malo otsiriza a mkono wa servo
- nthawi yozungulira mkono wonse: 1 sekondi
- kusintha kosalala kwa malo a mkono (kupyolera mwa aliyense
- chiwonetsero chazithunzi - LED
- magetsi 8÷18 V DC
Kufotokozera mozungulira
Chithunzi chojambula cha wolamulira chikuwonetsedwa mu Chithunzi 1. Lili ndi zinthu zochepa chabe. Diode ya D1 imateteza motsutsana ndi kulumikizidwa kumbuyo kwa voliyumu yoperekeratage, US1 stabilizer imapereka 5 V kulimbitsa servo, ndipo kudzera mu fyuluta yowonjezera yokhala ndi zinthu R3 ndi C3 imapatsanso mphamvu US2 microcontroller. R4 resistor imateteza kuyika kosankhidwa kwa boma, R5 imateteza kutulutsa kwamphamvu, R6 imathandizira gawo logwira ntchito la microcontroller, ndipo R7 imalepheretsa mawonekedwe a D2 LED. Ma R1 ndi R2 potentiometers amagwiritsidwa ntchito kuyika ma voliyumu awiritagma e values, omwe pambuyo pake amawongolera magawo a ma pulses pazotulutsa. Timagwirizanitsa voltage ku cholumikizira cha PWR kuchokera pamitundu ya 8…18 V, pomwe cholumikizira cha SERVO timalumikiza servo, molingana ndi zolembera pa bolodi. 0 V kapena 5 V imagwiritsidwa ntchito kutsogolera 2 ya cholumikizira cha SW, chomwe chimayika servo m'malo awiri. Kugwira ntchito kwa dera kumayendetsedwa ndi pulogalamu yomwe ili mu kukumbukira kwa microcontroller, chithunzi chake cha block chikuwonetsedwa mu Chithunzi 2. The TIMER? timer circuit ndi kauntala ya 16-bit yomwe idagwiritsidwa ntchito kupanga zosokoneza pa 20 ms iliyonse, motero zimakhazikitsa nthawi yotulutsa mawonekedwe. Kusokoneza kumachitika pamene kauntala ikusefukira. Chowerengera cha Timer chimagwiritsidwa ntchito kudziwa kutalika kwa kugunda.
Kuyamba kwake kumalumikizidwa ndi kusokoneza kuchokera ku Timer1, ndipo kusefukira kwake kumatulutsa kusokoneza kwachiwiri komwe kumamaliza kugunda ndikuyimitsa kauntala. Nthawi yosokoneza, motero nthawi ya kugunda, imatsimikiziridwa ndi kusintha mtengo woyamba wa counter, womwe umagwirizana ndi zotsatira za kutembenuka kwa A / C. Choncho, kusintha voltage mumitundu ya 0…5 V pakulowetsa kwa ADC, kumayambitsa kusintha kwanthawi ya kugunda kwapakati pa 0.5…2.5 ms.
Kuphatikiza apo, boma pakulowetsa kwa SW limasankha potentiometer (R1 kapena R2) yomwe ingatsimikizire vol.tage pakulowetsa kwa chosinthira. Izi zimalola kuti servo iwongoleredwe m'maiko awiri kudzera pakulowetsa kwa SW kapena kuchuluka kwathunthu posintha malo a potentiometers.

 Chithunzi cha 2 Kuyika kwa wowongolera |
Assembly ndi poyambira
Chipangizocho chinasonkhanitsidwa pa bolodi ladera losindikizidwa, chithunzi cha msonkhano chomwe chikuwonetsedwa mu Chithunzi 2. Msonkhano sufuna kufotokozera mozama, komabe, chidwi chochepa chiyenera kuperekedwa posonkhanitsa resistors R3…R7. Awa ndi ma SMD resistors, omwe amagulitsidwa mbali ina ya bolodi.

Chizindikirochi chikutanthauza kuti musataye katundu wanu ndi zinyalala zina zapakhomo.
M'malo mwake, muyenera kuteteza thanzi la anthu ndi chilengedwe popereka zida zanu zonyansa kumalo osankhidwa kuti azigwiritsanso ntchito zida zamagetsi ndi zamagetsi.
AVT SPV ili ndi ufulu wosintha popanda kuzindikira. Assembly ndi kugwirizana kwa chipangizo osati mogwirizana ndi zizindikiro mkati malangizo, mongosintha kusintha kwa zigawo zikuluzikulu ndi zosintha iliyonse structural kungayambitse kuwonongeka kwa chipangizo ndi kuvumbula owerenga kuvulaza. Zikatero, wopanga ndi oyimilira ake ovomerezeka sadzakhala ndi mlandu pakuwonongeka kulikonse komwe kumachitika mwachindunji kapena mwanjira ina chifukwa chogwiritsa ntchito kapena kusagwira ntchito kwa chinthucho.
Zida za DIY zimapangidwira maphunziro ndi ziwonetsero zokha. Sanapangidwe kuti agwiritsidwe ntchito pazamalonda. Ngati agwiritsidwa ntchito pazinthu zotere, wogula amakhala ndi udindo wonse woonetsetsa kuti akutsatira malamulo onse.
