Umthombo ovulekileyo: Inkqubo yoNikezelo lwaManzi rhoqo ngoxinzelelo oluSekwe kwiCOF Screen ——Ukusuka kwiQonga loPhuhliso lweDWIN

1. Umgaqo wokusebenza
Isisombululo sisebenzisa isikrini se-COF DMG80480F070_01WTR, esebenzisa i-chip ye-T5L njengowona lawulo oluphambili lokufumana kunye nokucwangcisa idatha yonikezelo lwamanzi eqokelelwe ngabenzi boluvo, ukuqhuba isikrini se-LCD ukubonisa idatha kunye nokulawula i-inverter ukulungisa isantya sempompo yepompo ukufikelela isiphumo esingaguqukiyo nesizinzileyo senkqubo yonikezelo lwamanzi. Kukho isilumkiso esingaqhelekanga kunye nemisebenzi yokumisela unikezelo lwamanzi yokwabelana ngexesha.

2. Uyilo lweskimu
(1) Umzobo webhloko yeskimu
(2)Idayagram yebloko ye-Hardware

(3) uyilo lwe-interface ye-DGUS GUI

(4)Uyilo lweSekethe
1.AD
Ikakhulu iqokelela izinzwa eziqhelekileyo ze-4-20MA/0-5V, iguqula uhlobo lwangoku lombane ukuya kwi-0-3V, kwaye emva kokubala kwe-AD unokufumanaidatha yoluvo oluhambelanayo.

AD Reference Code

2. Ewe
I-pwm isetyenziselwa ukulawula i-voltage ye-analogue kwaye ikhupha i-0-10V isignali yokulawula nge-op-amp.

Isicwangciso sokufumanisa i-DC

7.PID
I-algorithm ye-PID ye-possional isetyenziswa ikakhulu, imveliso ilinganiselwe, nikela ingqalelo ekuzalweni kwexesha elidibeneyo, kwaye umphumo kukulawula umbane we-analog ye-PWM.

8.Ezinye iikhowudi
Ukusetha okuzenzekelayo koxinzelelo lokuqala ngokwexesha.
