Umthombo ovulekile: I-Constant Pressure Water Supply System Esekelwe Esikrinini se-COF ——Kusuka Iforamu Yokuthuthukisa i-DWIN

1. Isimiso sokusebenza
Isixazululo sisebenzisa isikrini se-COF DMG80480F070_01WTR, esisebenzisa i-chip ye-T5L njengesilawuli esikhulu sokwamukela nokucubungula idatha yokuphakelwa kwamanzi eqoqwe izinzwa, ukushayela isikrini se-LCD ukuze kuboniswe idatha nokulawula inverter ukulungisa isivinini se-pump motor ukuze uzuze umphumela ongaguquki futhi ozinzile wohlelo lokuhlinzeka ngamanzi.Kunesexwayiso esingavamile kanye nemisebenzi yokuhlela ukuphakelwa kwamanzi kokwabelana ngesikhathi.

2. Ukwakhiwa kwesu
(1) Umdwebo webhulokhi yeskimu
(2)Umdwebo we-Hardware block

(3)Idizayini yesixhumi esibonakalayo se-DGUS GUI

(4)Idizayini yesiyingi
1.AD
Ikakhulukazi iqoqa izinzwa ezivamile ze-4-20MA/0-5V, iguqule uhlobo lwamanje lwe-voltage lube ngu-0-3V, futhi ngemva kokubala kwe-AD ingatholaidatha yenzwa ehambisanayo.

AD Reference Code

2.DA
I-pwm isetshenziselwa ukulawula i-analogue voltage futhi ikhipha isignali yokulawula engu-0-10V nge-op-amp.

Ikhodi Yereferensi ye-DC

3.IO ingxenye yokufaka
Ikakhulu okokufaka kwe-optocoupler, i-T5L ithola izinguquko ezihambisanayo zeleveli.

4.IO okukhiphayo
I-IO eyinhloko ye-Darlington Transistor yokulawula okuphumayo futhi i-IO ilawula amazinga aphezulu naphansi.

7.PID
I-algorithm ye-PID yesikhundla isetshenziswa kakhulu, okukhiphayo kunomkhawulo, naka ukugcwala kwethemu elibalulekile, futhi umphumela uwukulawula i-analog voltage ye-PWM.

8.Amanye amakhodi
Ukusetha okuzenzakalelayo kokucindezela kokuqala ngokuya kwesikhathi.
