1. Mfundo yogwira ntchito
Njira yothetsera vutoli imagwiritsa ntchito chophimba cha COF DMG80480F070_01WTR, chomwe chimagwiritsa ntchito chipangizo cha T5L monga chiwongolero chachikulu cholandirira ndi kukonza deta yamadzi yomwe imasonkhanitsidwa ndi masensa, kuyendetsa chophimba cha LCD kuti chiwonetsere deta ndikuwongolera inverter kuti isinthe liwiro la mpope kuti mukwaniritse zokhazikika komanso zokhazikika za dongosolo loperekera madzi.Pali chenjezo losazolowereka komanso kugawana nthawi yokhazikitsa madzi.

2. Kupanga dongosolo
(1) Chithunzi cha block block
(2) Chithunzi chojambulidwa cha Hardware block

(3) DGUS GUI mawonekedwe mawonekedwe

(4) Mapangidwe a Dera
1.AD
Makamaka amasonkhanitsa ochiritsira 4-20MA/0-5V masensa, otembenuka voteji-panopa mtundu kukhala 0-3V, ndipo pambuyo kuwerengera AD akhoza kupezadata yofananira ya sensor.

AD Reference Code

2.DA
Pwm imagwiritsidwa ntchito kuwongolera voliyumu ya analogue ndikutulutsa chizindikiro chowongolera cha 0-10V kudzera pa op-amp.

3.IO gawo lolowera
Makamaka zolowetsa za optocoupler, T5L imazindikira kusintha kofananirako.

IO hardware schematic

IO Input Reference Code

Zotsatira za 4.IO
IO yayikulu ya Darlington Transistor yotulutsa zowongolera ndipo IO imawongolera milingo yayikulu ndi yotsika.

6.485
Gwiritsani ntchito zida za Hardware kuwongolera kutumiza ndi kulandira mapini.

485 Hardware Schematic

7.PID
Positional PID algorithm imagwiritsidwa ntchito makamaka, zotulukazo ndizochepa, tcherani khutu pakuchulukira kwa mawu ofunikira, ndipo zotsatira zake ndikuwongolera mphamvu ya analogi ya PWM.

8.Makodi ena
Kukhazikitsa kokhazikika kwa kukakamiza koyambira molingana ndi nthawi.
