Txoj haujlwm no qhia koj yuav ua li cas thiaj ua tau tus noog zoo nkauj uas haus dej.

Koj tuaj yeem saib tus noog ua haujlwm hauv video.

Tus oscillator yog tsim los ntawm qhov yooj yim flip-flop Circuit Court uas tshwm sim thaum tus noog kov ib qho ntawm ob qhov kev sib cuag.

Khoom siv

Koj yuav xav tau:

- lub thawv khoom siv, - dc lub cev muaj zog (koj tsis xav tau lub zog muaj zog, tsis txhob siv lub cev muaj zog qis uas yuav tsis tuaj yeem tig cov noog loj lub cev loj), - 2 hli lossis 1.5 hli xaim, - 0.9 hli hlau, - 9 V roj teeb kom siv lub zog txuas lossis lwm lub roj teeb yog tias koj nrhiav tsis tau 9 V relay. Lub Circuit Court yuav tsum ua haujlwm ntawm 3 V yam tsawg kawg lossis txawm tias 2 V nyob ntawm cov khoom siv uas koj siv. Yog tias koj tab tom siv 3 V lub zog xa khoom siv tom qab ntawd hloov qhov tsawg kawg 2 volts vim tias lub roj teeb hluav taws xob yuav poob nrog lub sijhawm raws li lub roj teeb tawm, - DPDT (ob chav ncej ob zaug pov tseg) relay (12 V relay yuav ua haujlwm nrog 9 V), - ob lub roj teeb 1.5 V lossis kho lub zog hloov pauv kom lub zog dc lub cev muaj zog. Ob lub roj teeb 1.5 V tso rau hauv koob yuav muab 3 V uas yog qhov hluav taws xob uas xav tau rau feem ntau DC lub cav me. Txawm li cas los xij, 3 V tsis haum rau txhua lub cav. Siv qhov ntsuas hluav taws xob tsim nyog rau lub tshuab kom muaj lub zog txaus los tig cov noog hlau loj hauv lub cev. Thov khij nrog cov lus tshwj xeeb thaum koj xaj online lossis yuav hauv khw. Qhov no yog vim li cas kev hloov kho lub zog tuaj yeem yog lub tswv yim zoo.

- ob lub hom phiaj dav dav PNP BJT (Bipolar Junction Transistor) (2N2907A lossis BC327), tsis txhob siv BC547 lossis lwm qhov pheej yig qis tam sim no transistors, - ob lub hom phiaj dav dav NPN BJT (2N2222 lossis BC337) lossis ib lub hom phiaj dav dav NPN thiab ib lub zog transistor BJT NPN (TIP41C), tsis txhob siv BC557 lossis lwm yam pheej yig qis tam sim no transistors, - ob 2N2907A lossis BC337 transistors (koj tuaj yeem siv TIP41C fais fab transistor los tsav qhov hloov pauv hloov 2N2907A/BC337), - peb 2.2 kohm resistors, - plaub 22 kohm resistors, - ib qho 2.2 ohm siab zog tiv thaiv (xaiv tau - koj tuaj yeem siv luv Circuit Court), - ib lub hom phiaj dav dav diode (1N4002), - soldering hlau (xaiv tau - koj tuaj yeem ntswj cov xov ua ke), - xov hlau (ntau xim).

Xaiv 344.2: 1 iav piv, uas yog lub zog siab tshaj plaws thiab nrawm tshaj.

Koj tuaj yeem yuav lub thawv iav sib dhos lossis siv ib qho los ntawm lub tsheb qub tswj chaw taws teeb. Yog tias qhov nrawm yuav nrawm koj tuaj yeem txo qis lub zog hluav taws xob mus rau lub cav.

Kauj Ruam 2: Tsim Tus Sawv Cev Rau Tus Noog

Tus noog yog qhov siab 30 cm thiab ua rau feem ntau yog los ntawm 2 hli nyuaj hlau.

Tom qab koj ua tus noog koj txuas nws mus rau lub zog los ntawm 0.9 hli xaim.

Sim ua kom cov noog lub cev me me li sai tau tab sis nco ntsoov tias nws kov cov xov hlau. Siv 1.5 mm hlau hlau hloov 2 mm hlau hlau yuav txo tus noog lub cev qhov hnyav nce qhov kev pheej hmoo ntawm cov duab puab txav tau ua haujlwm tiag tiag vim tias lub tshuab DC me me yuav tsis tuaj yeem txav lub cev loj noog.

Kauj Ruam 4: Muab tus noog tso rau sawv ntsug

Txuas cov terminals pem hauv ntej thiab tom qab. Lub davhlau ya nyob twg sab nraub qaum yog tsim los ntawm 0.9 hli xaim khoov rau hauv ib nrab ntawm lub voj voog (thov saib ze ntawm daim duab).

Tom qab ntawd txuas 2 hli xaim kom ua tiav rau lub davhlau ya nyob twg.

Lub Circuit Court yog shoing yog lub flip-flop Circuit Court uas tswj cov relay.

"Noog pem hauv ntej" yog lub davhlau ya nyob twg.

Qhov "noog sawv" yog lub davhlau ya nyob twg txuas.

Cov kab hluav taws xob tau qhia pom ob qhov ntsuas hluav taws xob tswj. Qhov tseeb muaj ob lub tshuab hloov pauv (ob lub dav hlau koj tau txuas rau hauv cov kauj ruam dhau los) thiab cov ntsuas hluav taws xob tswj tau suav nrog hauv Circuit Court vim tias PSpice software tsis tso cai rau cov khoom siv tshuab thiab tsuas yog ua hluav taws xob lossis hluav taws xob hluav taws xob.

2.2 ohm resistor yuav tsis xav tau. Qhov ntsuas hluav taws xob no tau siv yog tias cov xa hluav taws xob muaj qhov inductance siab yog luv luv rau lub sijhawm ntev kom txog thaum nws qhib. Qhov no tuaj yeem hlawv lub zog transistor. Yog tias koj tsis muaj lub zog siv hluav taws xob ntau dua li tso ob peb lub NPN transistors sib txuas, txuas tag nrho peb lub dav hlau mus rau ib leeg (txuas rau lub hauv paus, hauv paus rau tus khaws thiab tso rau emitter). Txoj kev no yog siv los ua qhov rov ua dua tshiab thiab txhawm rau txo lub zog tawm hauv txhua qhov transistor.

Lub dab dej sov ntawm lub transistor tsis suav nrog. Vim tias lub transistor tau saturated lub zog tso tawm tsawg heev. Txawm li cas los xij, lub zog tso tawm yog nyob ntawm qhov txuas. Yog hais tias lub relay siv hluav taws xob siab tam sim no yuav tsum suav nrog lub dab dej sov.

Cov qauv cua sov tso cua sov tso tawm tau qhia hauv qhov simulation Circuit. Koj tuaj yeem siv ib qho ntawm ob qho. Hauv ob qho qauv kev sib piv hauv Circuit Court yog siv rau cov qauv kub. Yog tias tsis muaj lub kiv cua txias thiab tsis muaj qhov cuam tshuam ntau dua li qhov ua kom sov ua kom sov yog xoom. Koj yuav tsum xav tias lub cuab yeej yuav kub hauv lub thawv. Lub zog tso tawm yog qhov tam sim no, qhov kub yog qhov muaj peev xwm hluav taws xob thiab qhov tsis kam yog qhov kub ua haujlwm.

Nov yog qhov koj xaiv lub dab dej kub tsis kam thiab cov ntaub ntawv kom kub dab dej tsis kam:

Lub Hwj Chim Tawm = Vce (tus neeg tso hluav taws xob tso tawm hluav taws xob) * Ic (tus neeg khaws khoom tam sim no)

Vce (collector emitter voltage) = 0.2 volts (kwv yees) thaum lub sijhawm saturation. Ic = (Fais fab mov - 0.2 V) / Relay Kuj (thaum nyob)

Koj tuaj yeem txuas lub ammeter los tshuaj xyuas seb tam sim no siv cov khoom siv txuas thaum twg.

Tshav Kub Kub Tiv Thaiv + Cov Ntaub Ntawv Kom Tshav Kub Kub Kub = (Qhov Siab Tshaj Plaws Transistor Kev Sib Txuas Kub - Chav Siab lossis Qhov Kub Kub Ib puag ncig) / Lub Hwjchim Tso Tawm (Watts) - Kev Sib Txuas Rau Cov Khoom Kub Kub

Qhov Siab Tshaj Plaws Transistor Kev Sib Txuas Kub thiab Kev Sib Txuas Mus Rau Cov Khoom Kub Kub tau teev tseg hauv cov lus qhia tshwj xeeb.

Case To Heat Sink Resistance nyob ntawm qhov hloov pauv cua sov, cov khoom siv ntxhua khaub ncaws kom sov thiab nce siab.

Yog li qhov siab dua yog lub zog tso tawm, qis dua yuav tsum yog lub dab dej kub tsis kam. Cov cua sov loj dua yuav muaj cua sov tsawg dua.

Ib qho kev xaiv zoo yog xaiv lub rhaub dej kub uas muaj cua sov tsis kam yog tias koj tsis nkag siab cov qauv no.

Lub relay tsis tas yuav yog qhov siab tshaj tam sim no. Qhov tseeb nws yuav tsum yog qhov qis tshaj tam sim no. Txawm li cas los xij, nco ntsoov tias lub cev muaj zog yuav nqus dej siab yog tias nws nres vim muaj teeb meem siv tshuab xws li teeb meem nrog lub thawv iav. Qhov no yog vim li cas kuv thiaj txiav txim siab tsis siv transistors los tsav lub cav. Txawm li cas los xij, muaj H choj txuas hluav taws xob sib txuas thiab H choj tiv thaiv kab hluav taws xob uas tuaj yeem siv los tsav lub cev muaj zog.
