How kuti tachometer nemaoko avo?

Asati kuita tachometer namaoko ako, unofanira kunzwisisa zviri mudziyo uyu. The chaishandiswa kuyera uwandu nokumukirana simba chikwata panguva kufamba. ruzivo urwu kunoratidzwa pamusoro kuratidzwa iri dashboard kana chaiyo sikirini. Funga zvinotaurwa pamusoro tachometer uye nzira zvichiita pachako.

tinoshandisa microcontroller

Kuti tachometer maoko ake pamusoro achishandisa microcontroller, unofanira zvinotevera mashoko:

• Zvakananga microboard, dzakakodzera Arduino dunhu.
• Set of resistors.
• Nokuti akatungamirira shanduro waida akatungamirira-maatomu akafanana.
• Diodes (michini uye fotoanalog).
• Monitor. Somuenzaniso, LCD-kuratidza.
• Chaishanda kunyoresa 74HC595 mhando.

In nzira zvakurukurwa mberi mutswe haasi kushanda, uye Manyiminya regulator. Izvi tichadzivisa matambudziko pamwe rotor ukobvu, nhamba mashizha Haazovi zvainoita mashoko uye achagona kuverenga mashoko pamusoro vachishandisa kutenderera dhiramu.

kwawakabva

Pasi riri danho nedanho gwaro sei kuti tachometer maoko ake pamusoro achishandisa microcontroller:

1. Chokutanga yakaisvonaka sandpaper nemibato chiedza uye photodiode chero bedzi regai kutora sandarara chimiro.
2. Kugadzirwa zvakafanana chinhu muchimiro rinoparadza, uye ipapo zvikamu zviviri vari vakabatana namira uye mavara nhema ruvara.
3. At yakazotevera mudariro akatasva diodes, izvo soldered waya.
4. Critical tsika resistors dzingasiyana, zvichienderana kushandiswa photodiode. The utetsa kuchaita kuti kuchinja potentiometer.
5. Zvaakanga adzidza akatungamirira redunhu yemotokari tachometer anogona kunzwisiswa kuti pane anopiwa vanoshanda mazita matomu masere. Mukuwedzera, dunhu kunosanganisira mushonga sekristaro kuratidza. Kugadzirisa girobhu racho mune dzimba zvinoitwa diki buri.
6. Panguva yokupedzisira danho kunodiwa kuti solder resistor (270 Ohm) kusvika diode, uye ipapo negomo akaibayirira panosangana. The controller kutaurwa kupinda cubic chubhu kuti anopa okuwedzera simba yechigarire.

Itai nyore tachometer nemaoko avo

Nokuti zvaAtemisi mudziyo ichi chinobviswa sezvikonzero nokuda karukureta. Ipfungwa Izvi rakanakira kwevaya vane chinhu mujinga dambudziko. Zvinokosha kucherechedza kuti mudziyo uyu haasi 100 muzana yakarurama, uye tachometer haangazozikamwi kutepfenyurwa pamusoro kuratidzwa nhamba rotations paminiti. Asi karukureta - munhu nzira yakanaka mamwe mano mumutsetse anonongedzera.

inductive kana dzakafanana controllers zvinoshandiswa kugadzira chiratidzo controller. Kana dhisiki kutenderera unoratidzwa chimwe chiratidzo pashure nomumwe chimurenga. Contact nesu panguva ino anofanira kuvhurwa. Vari kuvharwa apo chikwata anotambidza mamhepo Disc zino. Viewed tachometer (nemaoko avo, sezvataona, kuti nyore), kwakadai mhinduro wakanaka vaya zviitiko apo kuyerwa hadziwanzowaniki. Vaya vanoda tigare kumhanya controller, zviri nani kuti vasarudze kupfuura yakavimbika mudziyo.

udzvanyiriri

The nyore tachometer, nemaoko ake akaita pachishandiswa ari karukureta kushanda pashure pokunamatidza ari kutaura kuti kuwedzera kombiyuta bhatani.

Kuyerwa rotational nokukurumidza RPM sezvinotevera:

1. Zvachinja pamusoro karukureta.
2. Synchronously kusashanda "+" kiyi uye "1".
3. The Gadget anomhanya pairi, uye akaita nekuyera. Kuti vave nechokwadi kuverengwa yakarurama, pamwe karukureta anofanira kutanga stopwatch.
4. Mirira masekondi 30 uye ipapo kutarisa chidzitiro. Zvinofanira kuonekwa zvakakodzera ukoshi.
5. Nhamba iyi ndiyo nhamba nokumukirana mumasekonzi 30. Vachiwedzera mufananidzo vaviri, isu tiwane nhamba rotations paminiti.

analoginen Ipfungwa

Electronic tachometer, yakaitwa nemaoko ake nokuda Diesel kana peturu injini, rinonyatsotarira Kushandurwa Erekitironi tichimhanya uye kutakura nayo kuratidza chikwata. Kusiyana mudziyo uyu, ari digitaalinen muenzaniso iri dzikwanise vamwe analoginen kupomba kutevedzana kwezviitiko Kwemagandanga Achishandisa Kombiyuta, iyo kuverenga uye decrypted ne controller.

The kwakakwana akagadzirwa analoginen tachometer kunosanganisira anotevera zvinhu:

• Microboard izvo chinangwa - kutendeuka analoginen pulses.
• Wiring unobatanidza zvose pezvokuvamba mudziyo.
• Pakafunuka, iyo inoshanda kuratidzira chokupika.
• Museve, ine pamusoro ano kukosha.
• Special coils akabatana, achivimbisa yakarurama kushanda museve.
• The kuverenga controller inductive mhando mudziyo.

How kuti digital tachometer nemaoko avo

Mano ichi mhando ane chinangwa fanana asi zvakasiyana STRUCTURAL zvinhu. Kuvaka mudziyo yako, unofanira zvinotevera mashoko:

• Masere ikakuruma convert.
• Processor kuti anomuchinja kuti pulses kuva ngetani Kwemagandanga Achishandisa Kombiyuta.
• Ratidza kuratidza uchapupu.
• Midziyo zvinodzongonyedza mhando (rotation regulator) pamwe gudzazwi. Nokuti chinangwa ichi, mumwe anogona kushandisa anokosha shunts, zvichienderana chaizvo ezvinhu.
• The vachibhadharisa pakuchinja yokururamisa ruzivo.
• Uyezve, zviri processor inogona kwakabatana kuti controller coolant tembiricha, mhepo iri kabhini, injini Urume kufurirwa, uye zvakafanana.
• Kuti kugadzira kunowanzoitika nokushanda mudziyo vanofanira kuisa Software inokosha.

zvokuimba nadzurudzo

Zvokuimba motokari tachometer, nemaoko ake, hakurevi simba nerubatsiro uye masimba matunhu. Nomubato iri nokuramba wakaomerera panzira ndee zvachose magineti mhando. Kana kutenderera vortex munda choga entrains rinokosha mugaba kuti rinobva zvinhu. Mudenhere rayo kunoita kuramba kutenderera zononoka yechirimo. Mukuru nokukurumidza, zvikuru aishingaira vakatsauka mugodhi akashongedzerwa nomuseve.

The chikuru mukana zvokuimba mudziyo - nyore kugadzira uye hamutsvaki kuti vawane Magetsi. Pakati zvainovhiringidzawo vanogona kutaurwa yakakwirira zvakarurama, nemichina rezasi muganhu yakayerwa. Zvinokosha kucherechedza kuti katsono nokukurumidza pasi hakuna vakatsauka.

Diagnostics

Made noruoko tachometer vanogona sousingabatsiri. Kuti chakonzera dambudziko vanofanira kuti chirwere. In motokari akashongedzerwa ane inowanikwa Obd II, ongororo rinoitwa nokushandisa scanner. Uyezve, mashoko wemagetsi zvinogona kudzorwa kushandisa chero ari kufamba kweropa jenareta. The yakanakisisa Ipfungwa raizova anozivikanwa zano rakanaka, imwe oscilloscope kana Frequency yemabhuku.

Zvokuimba analoginen akaonekwa nokuda chibooreso kana sikurudhiraivha. In pamberi regulator kuitisa akurumidze macheki nyore. Rwemberi Chikamu waya ndee nenzira wokuisira, uye yakakomberedzwa iri nokuramba wakaomerera panzira ndee.

kugadzira

Repair mudziyo hakunganzi chakaoma chaizvo. Chinonetsa kugadzirisa module ane chiitiko ane mudunhu magetsi. Pashure mhosva localization vanofanira kutsiva chakaremara chinhu. Kazhinji, kazhinji dzakabvarurwa kupinda, kuonana paakati, ari Switch, magineti pamusoro crankshaft.

Pamwe zvokuimba musiyano iri nyore zvikuru. Zvaringana kutsiva chinhu, yakabuda kunze chiito kuti padivi itsva. With tachometers dzakadaro motokari vane yakakwirira mileage uye zvikuru kushandiswa motokari. Saka, wana chinhu hakuzovi kwakaoma mune motokari pamusika kana disassembly. Pashure yokugadzirisa mudziyo kubatana kunoda hapana calibration.

kuchinja

Tachometer pamusoro motokari, nemaoko ake, zvingada kuchinja. Nokuti michina kazhinji paminiti gwenya mugodhi chimurenga chakarurama outputs peya pulses, ari oscillator kakawanda anofanira kuisa panguva kaviri calibration mudziyo.

Kuti kugadzira mashoko tachometer haakonzeri matambudziko, zvinokosha kudzidza nheyo zambuko redunhu. Somuenzaniso, zvakaenzana zvikuru tsika resistors, ari voltage iri pfungwa vakaenzana, uye naizvozvo, hapana kuitika Rwako uye tsono riri razero. Kana kukosha wokutanga resistor kuderedza voltage kuwedzera pane imwe nguva, apo wechipiri anoramba kuzochinja. Current runoyerera napakati milliammeter uye museve ichatanga uchifamba. Izvi zvinoreva kuti pane kugara voltage uye pane imwe nguva yokuchinja rechipiri iri pakutanga nechinzvimbo, tsono tachometer inodedera hama kuti pakafunuka.

In mhedziso

Ita motokari maoko enyu Tachometer zvikuru zvechokwadi, varipo kana chikuru ruzivo zvemagetsi engineering chido. Zvose zvinodikanwa - zviri wakagadzirira dunhu, rimwe pokunamatidza simbi uye zvinokosha zvakawanda. Zvichatora basa hapana kupfuura mazuva maviri, pamwechete dismantling uye kugadzwa. Unogona kusarudza chigadzirwa maererano nezvavanoda, kubva zano nyore inobva karukureta kana zvikuru yepamusoro tachometer yakavakirwa ARDUINO zano. Usati slag, kuongorora nheyo dzose vanoti motokari yako.
