Lub Circuit Court muaj 3 ntu feem ntau.

Qhov Kev Sib Txuas:

Nws suav nrog 1602 LCD zaub nrog I2C module thiab lub cav nkag teb nrog lub khawm thawb. Cov zaub qhia pom qhov ntsuas kub, qhov kub tam sim no, Ntxuam nrawm thiab siv lub zog thiab cov xwm txheej tam sim no ntawm tus kov. Tus encoder yog siv rau ntau yam kev nkag mus thiab mus los ntawm cov kev xaiv thiab kev tswj hwm.

Qhov Sensor:

Nws suav nrog K-hom thermocouple rau kev ntsuas qhov ntsuas kub thiab hloov pauv reed rau kev txiav txim siab txoj haujlwm ntawm tus tuav. Cov thermocouple qhov hluav taws xob tau nce los ntawm op-amp mus rau qib ntsuas ntsuas los ntawm arduino. Qhov nce ntawm op-amp yog tswj los ntawm 200K luas lauj kaub.

Tshooj Tswj:

Muaj feem ntau 2 tus tswj hwm hauv Circuit no. Ib qho yog qhov yooj yim PWM Ntxuam nrawm tswj nrog MOSFET. Lwm qhov yog tus tswj kev sib cais rau lub rhaub dej. Nws suav nrog TRIAC uas tau tsav los ntawm opto-coupled DIAC thiab nws ua tiav los ntawm kev tswj tus naj npawb ntawm cov voj voos uas tau xa mus rau lub rhaub. 4N25 optocoupler pab tswj kev sib txuas nrog AC waveform.

Lub voj voog ntawm txoj haujlwm no nyuaj me ntsis, Yog li kuv xav kom koj siv lub tshuab luam ntawv tshaj li teev PCB. Yog tias koj xav ua koj tus kheej PCB Kuv tau txuas cov ntaub ntawv dav dawb hau hauv cov kauj ruam no. Tab sis, Yog tias koj xav kom lawv ua tiav los ntawm PCB tuam txhab tsim khoom koj tuaj yeem xaj nws los ntawm JLCPCB

Txoj haujlwm yog qhov tseem ceeb tshaj plaws ntawm txoj haujlwm thiab ua tsaug ntau rau sfrwmaker sau qhov program. Txoj haujlwm siv PID algorithm los tswj lub zog kom tswj tau qhov ntsuas kub. Nws ua haujlwm los ntawm kev tswj hwm tus naj npawb ntawm cov voj voos xa mus rau tus tuav ib ob.

Thaum tus maub los tig rau ntawm tus pas nrig yuav nyob hauv lub xeev OFF. Los ntawm kev tig lub encoder qhov kub thiab txias kiv cua tuaj yeem hloov kho. Xovxwm luv ntawm tus lej nkag yuav hloov ntawm tus kiv cua nrawm thiab teeb ntsuas kub.

Cov phom cua kub pib ua kom sov sai li sai tau thaum nws nqa los ntawm tus tuav thiab qhia tias Npaj thiab ua suab nrov luv luv thaum nws mus txog qhov ntsuas kub. Nws yuav tua cua sov kom sai li sai tau thaum nws muab rov qab rau hauv tus tuav. Tab sis, tus kiv cua yuav tshuab txuas ntxiv mus txog thaum nws mus txog qhov ntsuas kub nyab xeeb. Tom qab qhov kub poob qis dua 50 C nws yuav ua rau luv luv beep thiab qhia COLD.

Thaum rab phom cua kub tawm, tus tswj hwm yuav nkag mus teeb hom yog tias tus lej nkag mus tau ntev.

Hom teeb tsa muaj Calibrate, Tune, Save and Cancel and Reset Config options.

Nco tseg: Yog tias koj siv PCB los ntawm easyEDA ces koj yuav tsum hloov tus lej tus lej ntawm reed hloov mus rau tus lej tsis yog. 8 thiab Buzzer tus pin rau tus lej 6

koj yuav tsum teeb tsa Commoncontrols-master library thiab time-master library rau txoj cai kom ua haujlwm tau zoo.

Kev ntsuas kub yuav tsum tau ntsuas nrog tus nqi qub kom tau txais kev nyeem tsim nyog. Yog li, txhawm rau ua qhov ntawd koj yuav tsum ua raws cov theem hauv qab no.

Ua ntej, mus rau hom teeb tsa thiab xaiv Tune optionIn the tune mode the internal temperature (0-1023) is displayed on the screen. Rotate the encoder to manually select the applied power to the hot air gun. Ua kom sov rab phom mus rau 400 degrees. Thaum kub thiab kev sib faib ua qis, tus tswj lub suab nrov. Tom qab ntawd qhib lub lauj kaub tais diav los teeb qhov ntsuas kub sab hauv txog 900 (hauv cov chav sab hauv). Nias ntev mus rau tus lej nkag rov qab rau cov ntawv qhia zaub mov

Tom qab ntawd, mus rau hom teeb tsa xaiv Calibrate xaiv. Xaiv qhov ntsuas ntsuas: 200, 300 lossis 400 degrees, nias tus lej nkag. Cov phom kub yuav mus txog qhov xav tau kub thiab nrov nrov. Los ntawm kev tig lub encoder, nkag mus rau qhov kub tiag tiag. Tom qab ntawd xaiv lwm cov ntsiab lus siv thiab rov ua cov txheej txheem no rau txhua qhov ntsuas ntsuas.

Tom qab nias ntev no thiab los rau lub vijtsam tseem ceeb thiab tom qab ntawd rov mus rau Teeb hom thiab xaiv txuag.

Thiab tam sim no Lub Chaw Cua Kub rov ua haujlwm tshiab tau ua tiav.
