Open source: Constant Pressure Water Supply System Yakavakirwa paCOF Screen ——Kubva kuDWIN Gadzira Forum

1. Kushanda musimboti
Mhinduro inoshandisa iyo COF skrini DMG80480F070_01WTR, inoshandisa iyo T5L chip seyakanyanya kutonga kugamuchira uye kugadzirisa data rekupa mvura inounganidzwa nemasensor, kutyaira iyo LCD skrini yekuratidzira data uye kudzora inverter kugadzirisa pombi mota kumhanya kuti uwane nguva dzose uye yakagadzikana mhedzisiro yehurongwa hwekupa mvura.Kune yambiro isina kujairika uye yekugovana nguva-yekugovera mvura yekuisa mabasa.

1.AD
Inonyanya kuunganidza akajairwa 4-20MA/0-5V sensors, inoshandura iyo voltage-yazvino mhando ku0-3V, uye mushure mekuverenga AD inogona kuwanainoenderana sensor data.

AD Reference Code

2.DA
Iyo pwm inoshandiswa kudzora analogue voltage uye inoburitsa 0-10V yekudzora chiratidzo kuburikidza ne-op-amp.

3.IO chikamu chekuisa
Kunyanya optocoupler inopinza, T5L inoona inoenderana nhanho shanduko.

IO Input Reference Code

4.IO yakabuda
Iyo IO huru yeDarlington Transistor inobuda inodzora relay uye iyo IO inodzora yakakwirira uye yakaderera mazinga.

5.RTC
RX8130, 2-waya kutaurirana.

RTC Hardware Schematic

RTC Reference Code

6.485
Kunyanya shandisa Hardware kudzora kutumira uye kugamuchira mapini.

485 Hardware Schematic

7.PID
Iyo positional PID algorithm inonyanya kushandiswa, inobuda ishoma, teerera kune kuzara kweiyo yakakosha izwi, uye mhedzisiro ndeye kudzora analog voltage yePWM.

8.Mamwe makodhi
Kugadzika otomatiki kwekumanikidza kwekutanga zvinoenderana nenguva.
