Indlela yokwenza tachometer ngezandla zabo?

Phambi ukwenza tachometer ngezandla zenu, kufuneka baqonde iimpawu kule fowuni. Isixhobo kusetyenziswa nasekujongeni inani revolutions ye unit lwamandla ngexesha intshukumo. Le nkcazelo iboniswe kwidispleyi ibekwe kwi kwideshbhodi okanye screen ekhethekileyo. Cinga kumthetho tachometer kunye neendlela zokwenza ngokwakho.

sisebenzisa i microcontroller

Ukwenza tachometer ngezandla zakhe phezu ngokususela microcontroller, kufuneka ezi nkcukacha zilandelayo:

• Ngqo microboard, wesekethe ofanelekileyo Arduino.
• Cwangcisa of resistors.
• Version LED efunekayo LED-element.
• Ilight (infrared kunye fotoanalog).
• Monitor. Umzekelo, LCD-ukubonisa.
• ukubhalisa Utshintsho 74HC595 uhlobo.

Xa indlela kuxoxwe noqhoqhoqho ngakumbi akusebenzi, kwaye Regulator optical. Oku kuya siphephe iingxaki kunye Ebubanzini plane, inani iincakuba iya kuba nafuthe iingxelo yaye uya kukwazi ukufunda ulwazi malunga njengokujikeleza igubu.

yayiba

Ngezantsi linyathelo ngu step guide ngendlela yokwenza tachometer ngezandla zakhe phezu ngokwesiseko microcontroller:

1. Okokuqala sandpaper ukukhanya entle iphathwe kunye photodiode logama nje musa imilo flat.
2. Bokwenziwa isiqalelo efanayo ngohlobo ngezithandelo, uze iinxalenye ezimbini bajoyine ngcina bebala ngombala omnyama.
3. Ngelo kwisigaba enyusiweyo ode kamva, ukuba soldered macingo.
4. izinto ezingundoqo resistors iyahluka, kuxhomekeke photodiode esetyenzisiweyo. Uvakalelo iya kuvumela ukunyenyisa potentiometer.
5. Ekubeni wayefunda LED yesekethe yemoto tachometer ziyalandeleka apho olunikelwe irejista shift ziikhowudi ezisibhozo. Ukongeza, le sekethe luquka uboniso olunombala wamanzi akhazimlayo. Ukulungisa ibhalbhu kwi yezindlu yenziwa umngxuma omncinane.
6. Xa Inyathelo lokugqibela ezifunekayo solder resistor (270 Ohm) ukuya diode, uze entabeni ibe kwisokethi. Le isilawuli yaziswa ityhubhu cc olunika amandla lwemidlalo olongezelelweyo.

Yenza tachometer elula ngezandla zabo

Kuba ekwenziweni kwesi sixhobo sithathwa njengesiseko sokubala. Olu khetho ilungele labo bakunye kwisiseko element le ngxaki. Kubalulekile ukuqaphela ukuba le ifowuni ziqinisekileyo 100 ekhulwini, kwaye tachometer abuyi kusasazwa phezu kwidispleyi inani nokujikeleziswa ngomzuzu. Kunjalo wokubala - okunye okuhle kwezinye izixhobo ngendlela Imiqondiso emgceni.

nabaqondisi ezenza okanye ezifanayo asetyenziselwa ze esisebenza umqondiso. Xa ukujikeleza disk iyavezwa uphawu olunye emva revolution nganye. Qhagamshelana nathi kule ngongoma kufuneka kuvulelwa. Bona zivaliwe xa iyunithi eyipasile izinyo disc. Kujongwa tachometer (ngezandla zabo, njengoko sele sibonile, ukwenza kube lula ngokwaneleyo), olu hlobo isisombululo ezisemagqabini kwezo meko apho imilinganiselo zinqabile. Abo bafuna ukwenza ukuseka isantya isilawuli rhoqo, kungcono ukuba ukhetha i isixhobo inokuthenjwa.

ukuxhaphaza

Le tachometer kwecacileyo, ngezandla zakhe zenziwe ngokusekelwe wokubala emsebenzini emva ngelotha abafowunelwa ukuya ukongeza iqhosha computer.

Umlinganiselo le ojikelezayo zesantya RPM ngolu hlobo lulandelayo:

1. Yona phezu sokubala.
2. Synchronously iyasebenza iqhosha "+" yaye "1".
3. Igajethi isebenza kuyo, yaye wenza yomlinganiselo. Ukuqinisekisa ufundo ezichanekileyo, kunye ikhaltyhuleyitha kufuneka uqale istopwotshi.
4. Linda imizuzwana 30 uze ujonge kwikhusi. Kufuneka abonakale ixabiso elifanelekileyo.
5. Eli nani linani revolutions kwimizuzwana eyi-30. Phinda inani babini, siye sifumane inani nokujikeleziswa ngomzuzu.

ukhetho analog

tachometer Electronic, ezenziwe ngezandla zakhe diesel okanye injini ipetroli, sijoliswe kwi inguqu isantya electron ahambise kwi-unit elibonisiweyo. Ngokwahlukileyo kule fowuni, indlela yedijithali iguqulelwa ngokulandelelana ukubetha ethile analog of amaqanda abo, nto leyo kufundwa kwaye uguqulwa esisebenza.

Iseti epheleleyo tachometer analog ibandakanya ezi zinto zilandelayo:

• Microboard injongo - uguqulo pulses analog.
• Iingcingo zombane ohlanganisa zonke iziqalelo device.
• Isikali, nelisebenza ukubonisa ukusebenza.
• Utolo, nto leyo eye kwixabiso yangoku.
• axis coil Special, ukuqinisekisa ukusebenza oluchanekileyo utolo.
• Le isilawuli yokufunda isixhobo uhlobo ezenza.

Indlela yokwenza tachometer yedijithali ngezandla zabo

Devices yale hlobo abe nenjongo efana kodwa izinto ezahlukeneyo zesakhiwo. Ukuze ukwakha idivayisi yakho, kufuneka ezi nkcukacha zilandelayo:

• bit-Eight lokuguqulela.
• Iprosesa oguqula pulses ibe udederhu amaqanda kunye nabo.
• Bonisa ukuba babonise ubungqina.
• Izixhobo ziphazamise uhlobo (ukujikeleza Regulator) kunye lo mshini. Ukulungiselela le njongo, namnye umntu onokusebenzisa shunts ezikhethekileyo, kuxhomekeke kwimeko ezithile.
• Intlawulo zokususa ulwazi.
• Ukongezelela, iprosesa nga kuqhagamshelwa ubushushu isilawuli njengesipholisi, umoya kule ndlwana, injini xi fluid, nezinto ezinjengezo.
• Ukuba uqwalasele ukusebenza eqhelekileyo ifowuni kufuneka uzifakelele software eyodwa.

ukuguqulwa mechanical

tachometer imoto Mechanical, ezenziwe ngezandla zakhe, akudingi umbane kunye neziphaluka yolawulo. Shaft ke ubeka esisigxina uhlobo umazibuthe ngokusisigxina. Xa batshintshana endle omtsha idaliwe leyo entrains isikhongozeli ekhethekileyo izinto ngemagnethi. Entshinyeleni idala ukumelana ujikelezo spiral emthonjeni. Okuya uba mkhulu umsantsa ngesantya, oluthi ngakumbi baphambuke exhotyiswe ngotolo.

Eyona Basebenzisa kwisixhobo ngomatshini - uyilo elula yaye akukho mfuneko yokuba afumane amandla ombane. Phakathi ethile ukuze wachaza ukuchana ephakamileyo, yaye lulungisa komda omncinci yokulinganisa. Kubalulekile ukuphawula ukuba isantya inaliti ephantsi akukho baphambuke.

ekuxilongweni

Made by tachometer ngesandla iyonakala. Ukuchonga unobangela ngxaki kuya kufuneka wenze isifo. Xa Kwizithuthi interface OBD II, ukuqinisekiswa kwenziwa ngokusebenzisa vuavanyisi. Ngaphezu koko, lo isixhobo elektroniki ungalawuleka ngokusebenzisa nayiphi na ubume generator. Ukhetho engcono kungaba isixhobo elungileyo eyaziwa, i oscilloscope okanye ukwenzeka counter.

analog Mechanical axilonge umfutho okanye screwdriver. Xa phambi komlawuli ukuqhuba itshekhi isantya lula. Inxalenye emva intambo busisigxina kumnini, kwaye indawo emibonweni ezisisigxina.

zokulungisa

isixhobo Repair asithathwa nzima kakhulu. Eyona nto kunzima ukulungisa le modyuli umzekelo we isekethe yombane. Emva fault kwasendaweni kufuneka enye intwana alusebenzi. Njengomgaqo, kaninzi ngenxa yokungena odolo, isibonisi umfowunelwa, umenzi woluvo, umazibuthe phezu crankshaft.

Ngenxa uhlobo mechanical kulula kakhulu. Kwanele ukuba enye intwana, owayebonakele phantsi isithuba spare elitsha. Ekubeni tachometers ezinjalo eemoto mileage eliphezulu kwaye kakhulu kusetyenziswa izithuthi. Ngoko ke, ukufumana akuyi kuba nzima into kwimarike izithuthi okanye disassembly. Emva nokulungiswa udibaniso ifowuni ifuna akukho ekulinganisweni.

ukulungiswa

Tachometer ezimotweni, ezenziwe ngezandla zakhe, ukuze kufuna ukulungiswa. Ngenxa yokuba matshini ngokubanzi ngamnye Isalathisi motor shaft revolution ovelisa iperi pulses, amaza oscillator kufuneka lubekwe kabini isixhobo Ukulinganiswa.

Ukuze ukuqwalasela tachometer akuthethi kunokubangela iingxaki, kuyimfuneko ukuba ukufunda siseko kwisekethe kwebhulorho. Umzekelo, kunye Amanani alinganayo amaxabiso resistors, le ombane kule amanqaku alinganayo, yaye ngoko ke, akukho kwemali ekhoyo kunye inaliti ngomhla zero. Ukuba ixabiso resistor yokuqala ekunciphiseni ukwanda ombane i ngaxa lithile, ngoxa yesibini kuhlala ingatshintshanga. Zangoku aqukuqela milliammeter kunye Utolo singaqalisi ukuhamba. Oku kuthetha ukuba umbane rhoqo kwindawo yesibini utshintsho kwi kwindawo yokuqala, inaliti tachometer isusiwe kuthelekiswa isikali.

Ekuphetheni

Yenza izandla imoto yakho Tachometer kakhulu yokwenene, zikhona ukuba ulwazi olusisiseko zobunjineli bombane kunye inkanuko. Yonke into efunekayo - oko wesekethe sesilungile, ngentsimbi ngelotha kunye iinkcukacha ezisisiseko. Kuya kuthatha umsebenzi ngaphezulu akukho ngaphezu kweentsuku ezimbini, ndawonye ukudilizwa kunye nofakelo. Uyakwazi ukukhetha imveliso ngokweemfuno zabo: ukusuka kwisixhobo elula ezisekelwe sokubala okanye tachometer phambili ngakumbi ngokusekelwe ARDUINO scheme. Phambi kokuba uqale, ukuhlola lo mgaqo isixhobo rhoqo kwi imoto yakho.
