Qhib qhov chaw: Kev Siv Dej Tsis Txaus Siab Raws li COF Screen —— Los ntawm DWIN Tsim Lub Rooj Sib Tham

1. Lub hauv paus ntsiab lus ua haujlwm
Qhov kev daws teeb meem siv COF screen DMG80480F070_01WTR, uas siv T5L nti ua lub ntsiab tswj kom tau txais thiab ua cov ntaub ntawv dej ntws los ntawm cov sensors, tsav lub LCD npo rau cov ntaub ntawv tso saib thiab tswj lub inverter los kho lub twj tso kua mis lub cev muaj zog kom ua tiav ib tsis tu ncua thiab ruaj khov cuam tshuam ntawm cov khoom siv dej.Muaj cov lus ceeb toom txawv txav thiab lub sijhawm sib faib dej qhov chaw ua haujlwm.

2. Cov qauv tsim
(1) Scheme block diagram
(2) Hardware thaiv daim duab

(3) DGUS GUI interface tsim

(4) Circuit Court Design
1. AD
Feem ntau sau cov pa 4-20MA / 0-5V sensors, converts hom voltage tam sim no rau 0-3V, thiab tom qab AD xam taucov ntaub ntawv sensor sib raug.

AD Reference Code

2. DA
pwm yog siv los tswj qhov voltage analog thiab outputs 0-10V tswj teeb liab los ntawm op-amp.

6.485 ib
Feem ntau siv kho vajtse los tswj kev xa thiab txais pins.

485 Hardware Schematic

7. PIB
Lub positional PID algorithm yog tsuas yog siv, cov zis yog txwv, them sai sai rau lub saturation ntawm lub ntsiab lus, thiab qhov tshwm sim yog los tswj cov analog voltage rau PWM.

8.Lwm cov lis dej num
Tsis siv neeg teeb tsa ntawm qhov pib siab raws li lub sijhawm.
