Me pēhea te ki te hanga i te tachometer ki o ratou ringa?

I mua i te mahi i te tachometer ki o koutou ringa, e hiahia ana koe ki te matau i te ngā āhuatanga o tenei pūrere. Ko te mea e whakamahia ana ki te ine i te maha o takaí o te kōwae mana i roto i te kaupapa. whakaaturia ana tēnei kōrero i runga i te whakaatu kei i runga i te Papatohu ranei i roto i te mata motuhake. A feruri i te parau tumu o te tachometer me ngā tikanga o te hanga i te reira koe.

whakamahi tatou he microcontroller

Hei hanga i te tachometer ki ona ringa i runga i te pūtake o te microcontroller, e hiahia ana koe te kōrero e whai ake:

• Tika microboard, e tika ana ara iahiko Arduino.
• Whakatakotoria he o parenga.
• Hoki putanga arahina hiahiatia arahina-huānga.
• Te p (pōkākā, me te fotoanalog).
• Kaupane. Hei tauira, LCD-whakaatu.
• Te neke rēhita 74HC595 momo.

I roto i te tikanga kōrero wāwāhi atu ko kore hāngai, me te regulator whatu. Ka karo raruraru ki te matotoru rotor tenei, ka kore he pānga i runga i te tauākī te maha o matatahi, a ka taea ki te pānui i ngā mōhiohio e pā ana ki te huringa o te drum.

tohu

Kei raro ko te taahiraa i te aratohu taahiraa pehea ki te hanga i te tachometer ki ona ringa i runga i te pūtake o te microcontroller:

1. Hei timata ki pepa pai marama whawha me te photodiode rite te roa rite kore ratou e tango i te āhua papatahi.
2. Hangaia rite huānga i roto i te puka o takai, a ka e piri nga wahi e rua i te piripiri, ka tae i roto i te tae pango.
3. I te wā eke te p muri, kua soldered ratou waea.
4. kia rerekē ngā uara Critical o parenga, i runga i te photodiode whakamahia rānei. Ka tukua te tūtohutanga ki te whakatika i te potentiometer.
5. Ka ako te pereoo tachometer ara iahiko arahina taea te mohio ki e reira te whakaratohia he rēhita neke o waru paraire. I tua atu, i te ara iahiko ngā te whakaatu kōataata wai. Hei whakatika i te umanga i roto i te whare mahi te poka iti.
6. I te taahiraa whakamutunga e hiahiatia ana ki te tūhoto parenga iahiko (270 Ohm) ki te ngōhiko, a ka Maunga reira ki te ateatenga. Kei te whakaurua te pūmana ki te ngongo pūtoru e whakarato tautara kaha tapiritia.

Hanga he tachometer ohie ki o ratou ringa

tangohia hoki te hanga o tenei pūrere te rite te pūtake mo te tātaitai. he pai hoki te hunga e te hunga ki te turanga huānga o te raruraru tenei kōwhiringa. E tano ia tapao e he tika e kore 100 ōrau tenei pūrere, a kore e te tachometer kia päpähotia i runga i te whakaaturanga i te maha o hurihanga ia meneti. Otiia tātaitai - he rerekē pai ki ētahi atu whakaaro i roto i te tohu rarangi.

E whakamahia pūmana inductive rite ranei ki te hanga i te pūmana tohu. A, no te whakaaturia hurihanga kōpae te kotahi tohu i muri i ia revolution. Whakapā mai ki tenei wāhi me whakatuwheratia. E katia ratou ina haere te kōwae te niho kōpae. I Tirohia tachometer (me o ratou ringa ake, i kite ai matou, kia kuware reira nui), he pai hoki te hunga wā i reira e onge nga inenga tenei momo o te otinga. Ko te hunga e hiahia ana ki te whakatū i tētahi pūmana tere auau, he reira pai ki te whakaputa hoki i te pūrere atu pono.

te faaohiparaa i

Te tachometer māmā, me ona ringa ake hanga i runga i te kaupapa o te tātaitai ki te mahi i muri i whakapiringa i te hoapā ki te tua o te pātene rorohiko.

Measurement o te Rpm tere hurihuri e whai ake:

1. Huri i te reira i runga i te tātaitai.
2. Synchronously whakahohe "+" kī me "1".
3. Rere ana te gadget ki runga taua mea, a ka meinga inenga. Ki te whakarite pānuitanga tika, me ki te tātaitai kia tīmata te stopwatch.
4. Taihoa 30 hēkona, me te ka titiro ki te mata. kia puta te reira i uara e tika ana.
5. Tenei ahua, ko te maha o takaí i 30 hēkona. Whakanuia te ahua i rua, whiwhi tatou i te maha o hurihanga ia meneti.

kōwhiringa tairitenga

tachometer Hiko, i hanga ki ona ringa ake mo te diesel engine penehīni ranei, kua arotahi ki runga i te huringa o te torohaki irahiko me te kawe i te reira ki te wae whakaatu. I roto i te rerekē ki tenei pūrere, kua tahuri te tauira mamati ki etahi raupapa pini tairitenga o ngā kore, me te hunga, kua kite i nei ka wetemuna e te kaiwhakahaere.

Ko te huinga katoa o te tachometer tairitenga ngā te huānga e whai ake nei:

• Microboard e whakaaro - te faafariuraa o ngātere tairitenga.
• Waea te hono nga āhuatanga katoa o te pūrere.
• Ko te tauine, i te kaimahi ki te whakaatu i te mahi.
• Ko te pere, e kua runga i te uara o nāianei.
• tuaka pōkai Motuhake, te whakarite i te mahi tika o te pere.
• Ko te pūrere momo inductive pānui pūmana.

Me pēhea te ki te hanga i te tachometer mamati ki o ratou ringa

Pūrere o tenei momo i te whakaaro ōrite, engari rerekē huānga hanganga. Hei hanga i tō ake pūrere, e hiahia ana koe te kōrero e whai ake nei:

• kaitahuri moka-waru.
• Pūtukatuka e tahuri te ngātere ki te mekameka o ngā kore, me te hunga.
• Whakaatu ki te whakaatu taunakitanga.
• Taputapu aruaru momo (hurihanga regulator) ki te tīwerawera. Hoki tenei whakaaro, kia whakamahi tetahi shunts motuhake, i runga i te āhuatanga motuhake rānei.
• Ko te utu mō te whakawātea mōhiohio.
• I tua atu, e taea te hono te pūtukatuka ki te pāmahana pūmana coolant, rangi i roto i te pēhanga inu piha, pūkaha, me te rite.
• Hei whirihora i te mahi noa o te pūrere Me ki tāuta pūmanawa motuhake.

whakarerekētanga aunoa

tachometer motokā Mechanical, i hanga ki ona ringa ake, e kore e rapua e te supply te mana me te iahiko mana. Kei te etaeta whakaritea te take momo aukume tūturu. A, no te tītaka mara vortex hanga te nei entrains te ipu motuhake o te rauemi autō. hanga puia ātete ki te puna hurihanga tōrino. Ko te nui te tere, te take ake kaha e whakakotititia ana rawa ki te pere.

Ko te painga matua o te pūrere aunoa - he hoahoa ohie, me kahore he take ki te whiwhi i te mana hiko. I roto i te drawbacks kia whakahuatia he tika tiketike, a Paraire te rohe o raro o te inenga. E tano ia tapao e kore te e whakakotititia ana te ngira tere iti.

tātaringa

Hanga e tachometer ringa hoki e taea te pakaru. Ki te tautuhi i te take o te raruraru ka Me ki te hanga i te tātaritanga. I roto i te waka rite rawa ki te atanga OBD II, whakamana whakaū kei te whakamahi i te matawai. Ano, e taea te whakahaere te pūrere hiko mā te whakamahi i tetahi o te generator he pini. e kia te kōwhiringa pai te pūrere pai mohiotia, he tīkorikori auau ranei counter.

tairitenga Mechanical pāngia e te drill huriwiri ranei. I roto i te aroaro o te regulator ki te whakahaere arowhai tere māmā. Ko te wahi muri o te taura whakaritea i roto i te taata tei mau, a ka te etaeta whakaritea te marae.

hanga

e kore te pūrere hanga whakaaro tino uaua. Ko te uaua tino ki te whakatika i te kōwae ko te tauira o te taiawhio hiko. I muri i tetahi he localization Me ki te whakakapi i te tūemi hapa. Ka rite ki te tikanga, tino maha i roto o te urunga kia, tohu whakapā, te pūoko, aukume i runga i te kawau hake.

Ki te kē aunoa ko nui māmā. Ko reira nui ki te whakakapi i te tūemi, i puta i roto i o te mahi mo te manawapa hou. Ki te taua tachometers motokā i tēnei pukapuka nui, me te e whakamahia kaha waka. Na reira, kitea kore e he tūemi e uaua i roto i te mākete automotive disassembly ranei. I muri i hanga o te hononga pūrere titau kahore whakatika.

whakatikatikanga

Tachometer i runga i cars, i hanga ki ona ringa ake, kia rapua e whakarerekētanga. No te mea te mihini te tikanga ia tohu nekeneke take revolution ngä te rua o ngātere, kia whakaturia te auau oscillator i rua i te pūrere whakatika.

Ki te whirihora e kore e te tachometer meinga raruraru, he mea e tika ana ki te ako i te parau tumu o te ara iahiko piriti. Hei tauira, me ōrite ana ngā wehenga uara o parenga, te ngaohiko i te ngā, he rite, a reira, kahore rerenga o nāianei, me te ko te ngira i te kore. Ki te ki te uara o te iahiko tuatahi whakaiti te hua ngaohiko i tetahi wāhi, i noho tonu te tuarua tonu. rere o nāianei i roto i te milliammeter a ka tīmata i te pere neke. tikanga o tēnei e i ngaohiko tamau, me i te wāhi tuarua o te huringa ko i te tūnga tuatahi, oho te ngira tachometer te whanaunga ki te tauine.

I roto i te mutunga

Hanga to koutou Tachometer ringa motokā tino tūturu, he hakari ki te te matauranga taketake o te engineering hiko, me te hiahia. hiahiatia katoa e te - te reira taiawhio rite, he rino whakapiringa me kōrero taketake. ka tango i te reira i mahi kaua e nui ake i te rua ra, tahi ki te tuuraki me tāuta. Ka taea e koe te whiriwhiri i te hua rite ki o ratou hiahia: i te pūrere ohie e hāngai ana i runga i te tātaitai te tachometer atu matatau e hāngai ana i runga i te kaupapa Arduino ranei. I mua i te koe tīmata, te tūhura i te parau tumu o te pūrere auau i runga i tou motokā.
