Sanadihii la soo dhaafay, dareemayaasha iyo tignoolajiyada ayaa aad iyo aad ugu badan oo loo isticmaalo mashiinnada dharka.Dareemaha ayaa ogaanaya heerka mashiinka dharka lagu dhaqo macluumaadka sidaheerkulka biyaha, tayada dharka, qadarka dharka, iyo shahaadada nadiifinta, waxayna u dirtaa macluumaadkan microcontroller.Kantaroolka-yar ayaa quseeya barnaamijka kontoroolka jahawareerka leh si uu u falanqeeyo macluumaadka la ogaaday.Si loo go'aamiyo wakhtiga ugu fiican ee dharka lagu dhaqo, xoojinta socodka biyaha, habka biyo raacida, wakhtiga fuuqbaxa iyo heerka biyaha, dhammaan habka mashiinka dharka ayaa si toos ah loo xakameynayaa.
Waa kuwan dareemayaasha ugu muhiimsan mashiinka dharka dhaqda oo si toos ah u toos ah.
Dareemaha tirada dharka
Dareemka culeyska dharka, oo sidoo kale loo yaqaan dareenka culeyska dharka, waxaa loo isticmaalaa in lagu ogaado tirada dharka marka la dhaqayo.Marka loo eego mabda'a ogaanshaha dareemayaasha waxaa loo qaybin karaa saddex nooc:
1. Marka loo eego isbeddelka hadda ee culeyska matoorka si loo ogaado miisaanka dharka.Mabda'a ogaanshaha waa marka culeysku weyn yahay, hadda matoorku wuu sii weynaadaa;Marka culeysku yar yahay, hadda matoorku wuu yaraanayaa.Iyada oo loo marayo go'aaminta isbeddelka dhaqdhaqaaqa hadda jira, miisaanka dharka ayaa lagu qiimeeyaa iyadoo loo eegayo qiimaha muhiimka ah ee wakhti go'an.
2. Marka loo eego sharciga isbeddelka xoogga elektiroonigga ah ee ka dhasha labada daraf ee dabaysha marka matoorka la joojiyo, waa la ogaanayaa.Mabda'a ogaanshaha ayaa ah in marka qadar gaar ah oo biyo ah lagu duro baaldiga dharka lagu dhaqo, dharka ayaa lagu ridayaa baaldiga, ka dibna matoorka darawalku wuxuu u shaqeeyaa habka hawlgalka tamarta kala go'a qiyaastii hal daqiiqo, iyada oo la adeegsanayo awoodda korantada induction ee ka dhalatay dabaylaha motor, by go'doomin photoelectric iyo isbarbardhigga nooca muhiimka ah, signal garaaca garaaca waa la abuuraa, iyo tirada garaaca wadnaha waa u dhiganta xagasha of inertia ee motor.Haddii ay jiraan dhar badan, caabbinta matoorku waa weyn yahay, xagasha inertia matoorku waa yar yahay, sidaas awgeed, garaaca garaaca wadnaha ee dareemayaasha waa yar yahay, si tirada dharka si aan toos ahayn "loo cabbiro".
3. Marka loo eego matoorka waditaanka garaaca wadnaha " leexo ", "jooji" marka xawaaraha garaaca garaaca wadnaha garaaca tirada dharka.Ku rid xaddi dhar iyo biyo ah baaldiga dharka lagu dhaqo, ka dibna garaac garaac si aad u wado matoorka, marka loo eego "on" 0.3s, "joojinta" 0.7s qaanuunka, hawlgalka soo noqnoqda ee 32s gudahood, inta lagu jiro matoorka "joogsiga" marka xawliga inertia, lagu cabbiro lammaane hab garaaca wadnaha ah.Inta dharka lagu dhaqo waa badan tahay, tirada garaacuna waa yar tahay, tirada garaacuna waa badan tahay.

Dareemaha marada waxa kale oo loo yaqaan dareeraha tijaabada marada, kaas oo loogu talagalay in lagu ogaado qaabka dharka.Codsiga Dareemaha culeyska dharka iyo beddelayaasha heerka biyaha ayaa sidoo kale loo isticmaali karaa dareemeyaal dhar ah.Marka loo eego saamiga suufka suufka iyo fiber kiimikaad ee fiber-ka dharka, dharka dharka ayaa loo qaybiyaa "suuf jilicsan", "suuf adag", "suuf iyo fiber kiimikaad" iyo "fiber kiimikaad" afar fayl.
Dareemka tayada iyo dareemaha tirada runtii waa qalab isku mid ah, laakiin hababka ogaanshaha ayaa kala duwan.Marka heerka biyaha ee baaldiga lagu dhaqo uu ka hooseeyo heerka biyaha go'an, ka dibna weli sida uu qabo habka cabbiraadda tirada dharka, u ogolow motor drive ka shaqeeyo in muddo ah jidka korontada, oo la ogaado tirada garaaca garaaca ee ay soo saarto qadarka dareenka dharka inta lagu jiro koronto kasta.Iyada oo laga jarayo tirada garaaca wadnaha tirada garaaca ee la helay marka la cabbirayo tirada dharka, farqiga u dhexeeya labada waxaa loo isticmaali karaa in lagu ogaado tayada dharka.Haddii saamiga fiilooyinka suufka ah ee dharka ku jira ay weyn yihiin, tirada garaaca garaaca wadnaha waa weyn yahay farqiga tirada garaacuna waa yar yahay.

Dareemaha heerka biyaha elegtarooniga ah ee ay gacanta ku hayso hal chip microcomputer ayaa si toos ah oo sax ah u xakameyn kara heerka biyaha.Heerka biyaha ee baaldiga wax lagu dhaqo way kala duwan yihiin, cadaadiska hoose iyo derbiga baaldiguna waa kala duwan yihiin.Cadaadiskan ayaa loo beddelaa qallafsanaanta diaphragm-ka caagga ah, si xudunta magnetic ee ku go'an diaphragm ay barakato, ka dibna inductance ee inductor waa la beddelaa, iyo inta jeer ee oscillation ee wareegga oscillation LC ayaa sidoo kale la beddelaa.Heerarka biyaha ee kala duwan, wareegga oscillation-ka LC wuxuu leeyahay soo-saarka calaamadaha garaaca wadnaha ee soo noqnoqda, calaamaduhu waa gelinta interface-ka microcontroller, marka heerka dareeraha heerka biyaha ee garaaca garaaca wadnaha iyo inta jeer ee la doortay ee lagu kaydiyo microcontroller isla waqti isku mid ah, microcontroller ayaa kara go'aanso in la gaadhay heerkii biyaha ee loo baahnaa, jooji duritaanka biyaha.
Heerkulka dharka ku habboon ayaa ku habboon kicinta wasakhda, waxay hagaajin kartaa saameynta dhaqidda.Dareemaha heerkulka biyaha ayaa lagu rakibay qaybta hoose ee baaldiga dharka, iyoNTC Thermistorwaxa loo istcimaalaa sida curiyaha ogaanshaha.Heerkulka la cabbiro marka la shido furaha mashiinka dharka lagu dhaqo waa heerkulka deegaanka, iyo heerkulka dhamaadka duritaanka biyuhu waa heerkulka biyaha.Calaamadaha heerkulka la cabbiray ayaa la geliyaa MCU si ay u bixiso macluumaadka fikradda daahsoon.

Dareemaha sawir-qaadista waa dareeraha nadaafadda.Waxa ay ka kooban tahay diode-yada iftiinka bixiya iyo sawir-qaadaha.Diode-ka iftiimiya iftiinka iyo sawir-qaadaha (phototransistor) ayaa si fool-ka-fool ah loogu dhejiyaa meesha ugu sarreysa ee biya-mareenka, shaqadeedu waa in la ogaado gudbinta iftiinka qulqulka, ka dibna natiijada baaritaanka waxaa lagu farsameeyaa microcomputer.Go'aanso dhaqidda, dareeraha, luqluqashada iyo xaaladaha fuuq-baxa.
