2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:24

Cov khoom siv hluav taws xob thaub qab yog cov khoom siv hluav taws xob rau cov khoom siv thaum lawv lub zog tseem ceeb poob qis. Hauv qhov no, cov khoom siv hluav taws xob thaub qab no tsuas yog xav muab lub zog rau ob peb feeb kom cov cuab yeej tuaj yeem ua nws txoj haujlwm kaw.

Kab lus no tau txhawb nqa los ntawm JLCPCB.comJLCPCB kuj tseem txhawb nqa txoj haujlwm no. JLCPCB (Shenzhen JLC Electronics Co., Ltd.), yog lub tuam txhab PCB loj tshaj plaws hauv Suav teb thiab cov chaw tsim khoom lag luam tshwj xeeb tshwj xeeb hauv PCB sai sai thiab tsim cov PCB me me. Koj tuaj yeem xaj yam tsawg kawg ntawm 5 PCBs rau tsuas yog $ 2. Txhawm rau kom tau txais PCB tsim tawm yooj yim upload.zip ntawm cov ntaub ntawv gerber lossis koj tseem tuaj yeem rub thiab poob cov ntaub ntawv.zip. Tom qab xa cov ntawv zip, koj yuav pom cov lus ua tiav hauv qab yog tias cov ntawv tau ua tiav tiav. Koj tuaj yeem tshuaj xyuas PCB hauv Gerber tus saib kom paub tseeb tias txhua yam zoo. Koj tuaj yeem saib ob sab saum toj thiab hauv qab ntawm PCB. Tom qab ua kom ntseeg tau tias PCB zoo, tam sim no koj tuaj yeem tso qhov kev txiav txim ntawm tus nqi tsim nyog. Koj tuaj yeem xaj 5 PCBs rau tsuas yog $ 2 ntxiv rau kev xa khoom. Txhawm rau txiav txim, nyem rau ntawm "SAVE TO CART" khawm.

Khoom siv

• 3x Low Forward Voltage Diodes (DFLS24L-7 tau siv)
• 2x 10 MOhm Resistors
• 1 x 348 kOhm Resistor
• 1 x 360 kOhm Resistor
• 1x 10W 100 Ohm Resistor
• 1x Sib Piv (LT1716 tau siv)
• 1 x 47 mF Capacitor
• 1x P-Channel MOSFET

Kauj Ruam 1: Simulation ntawm Circuit

Thawj kauj ruam ua ntej txhawm rau tsim PCB los tuav lub Circuit nws yuav tsum sim nws txhawm rau txhawm rau paub seb yuav tsum siv lub peev xwm li cas thiaj li muaj lub Circuit Court muab lub zog rau lub sijhawm xav tau. Nws tseem yog qhov tseem ceeb los xaiv qhov sib piv cov tswv yim tawm tsam kom nws tuaj yeem qhib thiab tawm ntawm MOSFET kom raug.

Raws li kev tsim khoom ntawm peb lub dashboard, lub zog siv hluav taws xob yuav tsum tau tswj kom tsawg kawg 5 vib nas this tom qab lub zog los ntawm tus pin hluav taws raug tshem tawm. Nws tseem yog ntshuam xa mus rau lub dashboard ua haujlwm nrog qhov muab hluav taws xob nruab nrab ntawm 24 thiab 9 VDC.

Txhawm rau ua qhov no peb txiav txim siab siv LTSPICE (simulation cov ntawv txuas nrog). Raws li nws tuaj yeem pom ntawm daim duab saum toj no, lub Circuit Court coj zoo li qhov xav tau. Cov khoom siv hluav taws xob, hauv ntsuab, tau qhib thiab yog li qhov hluav taws xob tso tawm tam sim ntawd muaj 24 V. Nyob rau tib lub sijhawm ua ntej them nqi ntawm lub tshuab hluav taws xob pib, cov kauj ruam no tseem ceeb heev vim yog lub peev xwm loj, txwv tsis pub qhov tam sim no yuav tshwm sim thaum lub kaw lus qhib. Thaum qhov hluav taws xob ntawm lub ntsuas hluav taws xob (V (them nqi)) yog nyob rau hauv qhov chaw nyab xeeb ntawm qhov nkag hluav taws xob lub qhov rooj ntawm MOSFET tau rub qis thiab yog li tam sim no hla dhau 100 Ohm ua ntej them tus tiv thaiv.

Thaum qhov hluav taws xob muab hluav taws xob tua (thib ob 31) peb tuaj yeem pom tias qhov hluav taws xob ntawm qhov tso tawm (V (dashboard)) pib txo qis. Qhov tseeb nws siv sijhawm kwv yees li 10 vib nas this kom nws qis dua 9 V cim, qhov no ua pov thawj tias 47 mF muab rau peb 100% cov paj laum uas ntau dua li txaus. Ntawm qhov kev sim no R7 sim ua kom lub nra, uas hauv lub neej tiag tiag yuav yog lub dav hlau tsav.

Kauj Ruam 2: Tsim PCB

Nrog rau lub Circuit Court twb tau xav thiab cov khoom tsim nyog xaiv nws yog tam sim no lub sijhawm los pib tsim PCB. Txhawm rau ua li ntawd peb siv Altium Designer. Lub Circuit Court yog ncaj ncaj rau pem hauv ntej thiab peb yuav tsis nthuav dav ntau txog nws hauv ntu no.

Kauj Ruam 3: Txiav txim rau PCB

Tom qab tsim qauv tiav nws yog lub sijhawm los xaj PCB. Yog li peb tau siv tus neeg txhawb nqa ntawm kab lus no JLCPCB.com

JLCPCB kuj yog tus txhawb nqa txoj haujlwm no. JLCPCB (Shenzhen JLC Electronics Co., Ltd.), yog lub tuam txhab PCB loj tshaj plaws hauv Suav teb thiab cov chaw tsim khoom lag luam tshwj xeeb tshwj xeeb hauv PCB sai sai thiab tsim cov PCB me me. Koj tuaj yeem xaj yam tsawg kawg ntawm 5 PCBs rau tsuas yog $ 2. Txhawm rau kom tau txais PCB tsim tawm yooj yim upload.zip ntawm cov ntaub ntawv gerber lossis koj tseem tuaj yeem rub thiab poob cov ntaub ntawv.zip. Tom qab xa cov ntawv zip, koj yuav pom cov lus ua tiav hauv qab yog tias cov ntawv tau ua tiav tiav. Koj tuaj yeem tshuaj xyuas PCB hauv Gerber tus saib kom paub tseeb tias txhua yam zoo. Koj tuaj yeem saib ob sab saum toj thiab hauv qab ntawm PCB. Tom qab ua kom ntseeg tau tias PCB zoo, tam sim no koj tuaj yeem tso qhov kev txiav txim ntawm tus nqi tsim nyog. Koj tuaj yeem xaj 5 PCBs rau tsuas yog $ 2 ntxiv rau kev xa khoom. Txhawm rau txiav txim, nyem rau ntawm "SAVE TO CART" khawm.

Kauj ruam 4: Sib dhos

Tom qab kwv yees li 1 lub lim tiam peb muaj PCB nrog peb thiab tam sim no yog lub sijhawm los sib sau ua ke.

Kauj ruam 5: Xeem

Tom qab lub rooj sib txoos, tam sim no yog lub sijhawm kom paub tseeb tias lub Circuit Court coj raws li qhov xav tau. Yog li peb tau siv lub tshuab hluav taws xob thiab peb tau tshuaj xyuas qhov hluav taws xob ntawm lub capacitor kom paub tseeb tias kev them ua ntej tau ua haujlwm raug (thawj daim duab), ntawm no peb tuaj yeem pom tias kev them rov qab ua ntej yuav siv sijhawm tsawg dua li qhov tau sim, tab sis qhov ntawd muaj ua nrog qhov sib txawv ntawm lub neej tiag tiag capacitor thiab simulated ib qho.

Tom qab them ua ntej tau ua tiav, peb tua lub hwj chim thiab pom qhov hluav taws xob ntawm qhov tso tawm. Raws li peb tuaj yeem pom qhov tso tawm qhov hluav taws xob tsawg zuj zus, raws li xav tau, nws siv yuav luag 12 thib ob rau qhov hluav taws xob mus qis dua 9 V, uas txhais tau tias peb cov haujlwm ua haujlwm!

Peb xav ua tsaug ib zaug ntxiv ua tus txhawb nqa ntawm kab lus no JLCPCB rau lawv txoj kev txhawb nqa zoo rau peb pab pawg nrog peb cov kev tsim khoom PCB! Nco ntsoov xaj los ntawm lawv lub sijhawm tom ntej koj xav tau PCBs.
