Abstract
Cov tsev tau ntse dua txhua hnub vim tias thev naus laus zis nyob ib puag ncig tam sim no. Daim ntawv thov siv hauv cov tsev ntse no yog LDR system. Kab lus no yuav qhia koj yuav tsim koj li LDR system li cas nrog cov cuab yeej yooj yim thiab yuav ntsuas nws li cas siv lub computer muag khoom muag thiab tsim qauv.
Kauj ruam 1: Taw qhia
Lub teeb yog qhov tseem ceeb ntawm txhua yam, koj tsis tuaj yeem pom yam tsis muaj lub teeb pom kev zoo. Qee zaum tib neeg xav tau txhua yam kom nrawm dua thiab ntse dua, tej zaum yog vim tibneeg hu tauj coob lossis teev sijhawm. Yog li, qhov kev sib tham no muaj lub luag haujlwm tseem ceeb hauv peb lub neej. Los ntawm kev siv LDR, koj tuaj yeem tswj kev kho txhua qhov kev qhia ntxaws ntsig txog teeb pom kev hauv koj chav. LDR tau siv ntawm no kom tso cai tam sim no hla lub LED kom qhib thaum xav tau. Koj tuaj yeem kho nws kom qhib thaum nruab hnub thaum nws hnov lub teeb, lossis hmo ntuj thaum nws hnov qhov tsaus ntuj. Xav tias txoj hauv kev no yuav ua rau koj yooj yim dua tig lub teeb thaum xav tau yam tsis tas tawm hauv koj qhov chaw siv lub transistor ua lub qhov rooj lossis hloov pauv kom tso cai tam sim no los ntawm kev nkag siab tau los ntawm LDR nrog kev pab ntawm qee tus tiv thaiv kom txwv qhov tam sim no rau lub neej ntev dua. Qhov no tuaj yeem raug coj mus rau lwm qib thiab tswj hwm txhua yam nyob ntawm lub teeb thiab cov duab ci kom ntse dua thiab siv hluav taws xob ntau dua li txoj kev ib txwm muaj.
Kauj ruam 2: LDR yog dab tsi
Nws yog semiconductor photoresistor hu ua uas hnov lub teeb thiab tsaus ntuj kom muab qhov tsis sib xws rau hauv Circuit Court nyob ntawm seb lub teeb pom kev ntau npaum li cas. Qhov kev sib raug zoo ntawm qhov tsis kam thiab lub teeb yog qhov sib piv sib piv, raws li qhov sib zog nws tau txais, ntau qhov kev coj ua nws dhau los, thiab tau kawg ua rau muaj kev tiv thaiv tsawg dua vim nws nce nws cov kev coj ua.
Kauj Ruam 3: Daim Ntawv Teev Npe
Txhawm rau tsim cov kab hluav taws xob no, tau kawg koj yuav tsum kos cov phiaj xwm ua ntej. Cov no yog cov khoom siv xav tau los kos cov txheej txheem:
1- 10k ohm resistor.
2- 360ohm resistor.
3- LWD.
4- LED.
5- BC 547 transistor.
9V roj teeb.
Kauj ruam 4: Schematic
Los ntawm kev siv KICAD software, peb tuaj yeem kos cov phiaj xwm hluav taws xob nrog cov ntsiab lus tau piav qhia raws li qhia hauv daim duab (1).
Kauj ruam 5: Kev sib txuas
Ib qho software yooj yim tau siv los txuas qhov kev pom no, uas yog Tinker Cad. Raws li tau qhia hauv daim duab (2), kev sib txuas tau txuas nrog siv cov khoom teev tseg saum toj no.
Nov yog yuav ua li cas txuas lub Circuit Court hauv ob peb kauj ruam yooj yim:
1- Muab lub khob cij los pab koj hauv kev sib txuas.
2- Txuas lub roj teeb 9V rau qhov zoo thiab qhov tsis zoo ib feem.
3- Txuas lub 10k resistor rau txoj kev tsheb nqaj hlau zoo, thiab lwm lub davhlau ya nyob twg ntawm nws mus rau txoj kev tsheb nqaj hlau qhib.
4- Txuas LDR mus rau tib txoj kev tsheb nqaj hlau, thiab lwm lub davhlau ya nyob twg mus rau txoj kev tsis zoo ntawm lub khob cij.
5- Muab lub transistor tso rau hauv 3 txoj kab sib txawv, vim tias txhua txoj kev tsheb nqaj hlau hauv daim ntawv qhia zaub mov sawv cev rau 1 kis.
6- Txuas lub davhlau ya nyob twg emitter mus rau qhov tsis zoo ntawm lub rooj tsavxwm.
7- Txuas lub hauv paus dav hlau mus rau tib txoj kev tsheb nqaj hlau uas txuas 10k tus tiv thaiv thiab LDR tsuas yog nruab nrab ntawm lawv.
8- Txuas lub davhlau ya nyob twg mus rau lub dav hlau cathode ntawm LED.
9- Txuas lub davhlau ya nyob twg zoo ntawm tus coj mus rau lub davhlau ya nyob twg ntawm qhov seem 360 ohms resistor.
10- Txuas lub davhlau ya nyob twg ntxiv ntawm tus tiv thaiv mus rau txoj kev tsheb nqaj hlau zoo ntawm pawg thawj coj saib.
11- Nco ntsoov tias koj txuas txoj kab zoo thiab tsis zoo ntawm lub rooj tsavxwm los ntawm ob sab mus rau ib leeg kom tswj tau lub voj kaw kom lub Circuit Court tuaj yeem ua haujlwm.
Kauj Ruam 6: Simulation
Los ntawm kev siv tib lub software (Tinker Cad), koj tuaj yeem pom tias lub Circuit Court ua haujlwm tau zoo lossis muaj qee qhov yuam kev lossis yuam kev uas koj yuav tsum tau saib xyuas zoo li hloov pauv qhov muaj txiaj ntsig lossis tshuaj xyuas LDR qhov kev nkag siab. Raws li tau qhia hauv daim duab (3) thiab (4), lub Circuit Court ua haujlwm tau zoo nrog cov txiaj ntsig no. Hauv daim duab (3), LED tawm, thaum LDR hnov lub teeb ntau.
Hauv daim duab (4), LED nyob raws li LDR hnov qhov tsaus ntuj.
Kauj Ruam 7: Tsim PCB
Nrog KICAD uas peb tau siv hauv cov txheej txheem; peb tuaj yeem tau txais PCB kom raug tom qab los ntawm cov chaw tsim khoom lag luam. Hauv daim duab (5) qhov kawg ntawm PCB.
Qee cov lus qhia koj yuav tsum tau saib xyuas thaum tsim PCB:
1- Nco ntsoov tias cov qhov hneev taw hneev taw nyob ntawm qhov kab sib chaws.
2- Nco ntsoov tias koj xaiv txheej kom raug.
3- Nco ntsoov tias qhov dav dav, 4- Ua kom ntseeg tau tias muaj tag nrho cov khoom nyob ze ib leeg kom tsis txhob nkim khoom thiab nyiaj txiag.
5- Nco ntsoov tias koj tau ntxiv cov npoo kom raug thiab sau zoned los tswj cov txheej tooj liab.
Kauj Ruam 8: 3D Saib ntawm PCB
Ntawm no koj tuaj yeem pom pem hauv ntej thiab nraub qaum 3D pom ntawm PCB.
Kauj Ruam 9: Xaus
Nws yog qhov ci ntsa iab los siv thev naus laus zis los ua koj li kev ua ib txwm muaj. Qhov no yuav ua rau koj muaj kev tshoov siab kom ua rau lub ntiaj teb yooj yim dua tsis yog koj lub tsev, tsuas yog xav txog qee tus thawj coj uas yuav tsum tau coj mus rau hauv tus account. Thawj tus thawj xibfwb yog lub sijhawm tseem ceeb, thiab qhov tseem ceeb ntawm kev ua kom txhua yam ntse dua thiab sai dua, tsuas yog siv qhov zoo tshaj plaws ntawm kev siv tshuab thiab ib puag ncig.
