Kodi kupanga tachometer ndi manja awo?

Pamaso kuchita tachometer ndi manja anu, muyenera kumvetsa mbali ya chipangizo ichi. The chida ntchito kuyeza chiwerengero cha kusintha kwa unit mphamvu pa gulu. Mfundozi anasonyeza pachionetsero yomwe imakhala pa galasi lakutsogolo kapena TV wapadera. Taganizirani mfundo za tachometer ndi njira kupanga nokha.

timagwiritsa ntchito microcontroller

Kupanga tachometer ndi manja ake pa maziko a microcontroller, muyenera mfundo zotsatirazi:

• Mwachindunji microboard, oyenera Arduino dera.
• Khalani a resistors.
• Pakuti LED Baibulo chofunika LED-amafotokozera.
• Diodes (infuraredi ndi fotoanalog).
• Muziona. Mwachitsanzo, LCD anasonyeza.
• kuloza kulembetsa 74HC595 mtundu.

Mu njira zafotokozedwa kudula zina sichiri, ndi yang'anira kuwala. Izi kupewa mavuto ndi ozungulira makulidwe, chiwerengero cha masamba sadzakhala ndi mphamvu pa mawu ndipo mudzatha kuwerenga zambiri za kasinthasintha wa ng'oma ndi.

yachitika

Pansipa ndi sitepe ndi sitepe kalozera kupanga tachometer ndi manja ake pa maziko a microcontroller ndi:

1. Kuyamba ndi zabwino sandpaper agwira kuwala ndi photodiode malingana ngati iwo musatenge mawonekedwe mosabisa.
2. Chopangidwa mchitidwe ofanana mu maonekedwe a n'kupanga, kenako mbali ziwiri likugwirizana ndi zomatira ndi akuda mtundu wakuda.
3. Pa nthawi wokwera diodes patapita iwo soldered mawaya.
4. mfundo kuweruza resistors zosiyanasiyana malinga photodiode ntchito. Tilinazo adzalola kusintha potentiometer.
5. Popeza ankaphunzira LED dera galimoto tachometer Tingathe kuona kuti pali anapereka kosangalatsa m'kaundula wa Akamva eyiti. Komanso, dera kumaphatikizapo kuwonetsera madzi galasi. Kukonza babu mu nyumba chikachitika dzenje yaing'ono.
6. Pa sitepe chomaliza chofunika solder resistor (270 ohm) kuti diode, ndiyeno phiri ilo mu bowo la. Mtsogoleri wa anadzetsa chubu kiyubiki amene amapereka chinanso mphamvu fixture.

Kupanga tachometer yosavuta ndi manja awo

Kupanga chipangizo ichi walandiridwa monga maziko a Chiwerengero. Izi njira ndi abwino kwa anthu amene ali ndi mchitidwe m'munsi mwa vuto. Dziwani kuti chipangizo chimenechi si 100 zolondola, ndi tachometer sati ukufalitsidwa pachionetsero chiwerengero cha kasinthasintha pa mphindi. Komabe Chiwerengero - wabwino zina zipangizo zina mwa zizindikiro mzere.

inductive kapena ofanana opha ntchito popanga mbendera Mtsogoleri. Pamene litayamba kasinthasintha chimaonetsedwa chizindikiro chimodzi pambuyo lililonse zisinthe. Lumikizanani nafe pa mfundo iyi ayenera adzatsegulidwa. Iwo anatseka pamene unit apatsira chimbale dzino. Ankaona tachometer (ndi manja awo, monga taonera, kuzipanga izo mophweka mokwanira), mtundu wa njira kwambiri milandu kumene miyezo n'zochepa. Amene akufuna kukhazikitsa liwiro zonse Mtsogoleri, ndi bwino kusankha chipangizo odalirika kwambiri.

yokumba

The tachometer losavuta, ndi manja ake anapanga pa maziko a Chiwerengero ntchito pambuyo soldering ojambula kuti Kuwonjezera batani kompyuta.

Muyeso wa rotational liwiro rpm motere:

1. Likukhalira pa Chiwerengero.
2. Synchronously adamulowetsa "+" ofunika "1".
3. The chida akuthamanga pa izo, ndipo anachipanga kayesedwe. Kuonetsetsa kuwerenga molondola, pamodzi ndi Chiwerengero ayenera kuyamba wotchi yoyimitsa.
4. Dikirani masekondi 30 kenako tayang'anani pa TV. Izo ziyenera kuonekera mtengo yoyenera.
5. chithunzi Ichi ndi chiwerengero cha kusintha masekondi 30. Yochulutsa chithunzi ndi awiri, timapeza chiwerengero cha kasinthasintha pa mphindi.

analogi njira

Pakompyuta tachometer, zopangidwa ndi manja ake kwa dizilo kapena injini mafuta, lolunjika pa kusintha kwa elekitironi patsogolo n'kukawatula kuti unit kudzionetsera. Mosiyana ndi chipangizo ichi, kachitidwe digito ndi n'kukhala ena zimachitika ndondomeko analogi wa ziro ndi anthu, limene kuwerenga ndi decrypted ndi Mtsogoleri wa.

The lonse la tachometer analogi zikuphatikizapo zinthu zotsatirazi:

• Microboard chifuno - kutembenuka kwa nyemba analogi.
• Kulumikizana kulumikiza zinthu zonse chipangizo.
• The lonse, amene akutumikira kuonetsera ntchito.
• Muvi, amene ali pa mtengo panopa.
• Special koyilo olamulira, kuonetsetsa ntchito olondola a muvi.
• Kuwerenga Mtsogoleri inductive mtundu chipangizo.

Kodi kupanga tachometer digito ndi manja awo

Zipangizo za mtundu uwu ndi zofanana cholinga koma zinthu zosiyana structural. Kumanga chipangizo anu, muyenera mfundo zotsatirazi:

• Eyiti-bit Converter.
• Purosesa kuti otembenuka nyemba mu unyolo wa ziro ndi anthu.
• Sonyezani kusonyeza umboni.
• Zida usokoneze mtundu (kasinthasintha yang'anira) ndi mkuzamawu lapansi. Chifukwa chaichi, munthu akhoza kugwiritsa ntchito shunts wapadera, zoopseza yeniyeni.
• Amalipiritsa zochotsera zambiri.
• Komanso, purosesa akhoza olumikizidwa kwa Mtsogoleri coolant kutentha, mpweya mu kanyumba, injini madzimadzi kuthamanga, ndi zina zotero.
• Kuti sintha ntchito yachibadwa chipangizo ayenera kukhazikitsa pulogalamu yapadera.

kusinthidwa mawotchi

Mawotchi galimoto tachometer, zopangidwa ndi manja ake, sikutanthauza ndi magetsi ndi madera kulamulira. Kutsinde ndi sankalimbana nafe atathana okhazikika maginito mtundu. Pamene limazungulira munda mmene kanyamaka analenga amene entrains ndi chidebe wapadera zakuthupi maginito. Ziyangoyango amalenga zoipa kasinthasintha mwauzimu masika. Kwakukulu liwiro, ndi kumufotokozera anapanduka kutsinde okonzeka ndi muvi.

The mwayi waukulu chipangizo makina - ndi kapangidwe yosavuta sipafunika kupeza mphamvu ya magetsi. Mwa zovuta mwina anatchula molondola mkulu, ndi kuchepetsa m'munsi malire a kayesedwe. Dziwani kuti otsika liwiro singano si anapanduka.

diagnostics

Yotentha ndi dzanja tachometer akhoza kuonongeka. Kupeza chifukwa cha vuto adzafunika kuti matenda. Mu galimoto zida ndi mawonekedwe OBD II, yachinsinsi imagwiridwa ntchito sikana. Komanso, pazipangizo akhoza lizilamuliridwa ntchito iliyonse ya jenereta zimachitika. Njira adzakhala kudziwika chipangizo chabwino, ndi oscilloscope kapena pafupipafupi kauntala.

Mawotchi analogi anapezeka ndi kubowola kapena screwdriver. Pamaso pa yang'anira kuchititsa macheke liwiro mosavuta. Mbali kumbuyo kwa chingwe cha chili mu chofukizira, ndipo mpanda ndi sankalimbana nafe lokhazikika.

kukonza

chipangizo kukonza si zovuta. Chovuta kwambiri kukonza gawo ndi chitsanzo cha dera magetsi. Pambuyo vuto kutanthauzira ayenera m'malo item zosalongosoka. Monga ulamuliro, nthawi zambiri kunja kwa dongosolo kulowa, kukhudzana chizindikiro, ndi kachipangizo, maginito pa crankshaft lapansi.

Ndi zosinthika makina ndi zosavuta. Chakwanira m'malo katunduyo, amene anaonekera mwa kanthu kwa wapadera latsopano. Ndi tachometers ngati magalimoto ndi mkulu mtunda ndipo kwambiri ntchito magalimoto. Choncho, chinthu sadzakhala zovuta msika magalimoto kapena disassembly. Pambuyo kukonza kugwirizana chipangizo amafuna palibe calibration.

kusintha

Tachometer pa magalimoto anapanga ndi manja ake, kungafune kusintha. Chifukwa makina zambiri pa galimoto kutsinde zisinthe chizindikiro zotuluka awiri nyemba, pafupipafupi oscillator ayenera upatsidwa kawiri chipangizo calibration.

Kuti sintha ndi tachometer sayambitsa mavuto, m'pofunika kuphunzira mfundo za dera mlatho. Mwachitsanzo, ndi mulingo ofanana khalidwe resistors, ndi voteji pa mfundo ofanana, komanso Choncho utuluke panopa ndi singano ndi pa ziro. Ngati mtengo wa resistor woyamba kuchepetsa kuchuluka voteji pa nthawi ina, pamene lachiwiri amakhalabe sichinasinthe. Current umayenda mwa milliammeter ndi muvi adzayamba ikuyenda. Izi zikutanthauza kuti pa voteji zonse ndi pa mfundo yachiwiri kusintha pa malo oyamba, tachometer singano anawamvera wachibale lonse lapansi.

pomaliza

Kupanga galimoto manja anu Tachometer ndithu weniweni, alipo ngati chidziwitso yaikulu ya zomangamanga magetsi ndi chilakolako. Ndiko chofunika - ndi wokonzeka dera, chitsulo soldering ndi mfundo zofunika. Kudzatenga ntchito zosaposa masiku awiri, pamodzi ndi dismantling ndi unsembe. Mukhoza kusankha mankhwala malinga ndi zosowa zawo: kwa chipangizo losavuta zochokera Chiwerengero kapena tachometer patsogolo kwambiri potengera ARDUINO chiwembu. Musanayambe, kufufuza mfundo chipangizo wokhazikika pa galimoto yanu.
