I-NE T NICD2411 Pid Process Controller

Isingeniso

Lesi isilawuli se-PID esisekelwe ku-micro-controller Cum Process Controller. Ithuluzi linamamodi amathathu eyodwa imodi ye-PID 2nd imodi yokudlulisela kabusha 3rd imodi yeManuwali. Abasebenzisi bangakhetha noma iyiphi, ake sithi umsebenzisi ukhetha imodi yesi-2 (Imodi yokudlulisa kabusha) Kule modi umsebenzisi angathatha okukhiphayo okungu-4-20mA ngokusho kokufaka. Kwimodi yesi-3 umsebenzisi angathatha i-4-20mA ngokusebenzisa ikhiphedi (ngesandla) . Isibonisi esiphezulu sibonisa inani lenqubo kanye nesibonisi esiphansi sibonisa inani lokuphumayo/Iphoyinti. I-Instrument ine-Modbus (RS485) Ukuxhumana kanye nokulawula oku-2 Relay. Isandulelo Siyabonga ngokuthenga isilawuli se-PID/Process Indicator NICD2411. Leli bhukwana lichaza imisebenzi eyisisekelo nezindlela zokusebenza ze-NICD2411. Sicela ufunde imanuwali yalo msebenzisi ngokucophelela ngaphambi kokusebenzisa umkhiqizo.

Ukusebenza

• Ngaphambi kokuxhuma ugesi qinisekisa ukuthi uxhuma i-I/P voltage kumatheminali angakwesokudla. Ekusetshenzisweni kokunikezwa kwamandla okufanele kanye nenzwa yokufaka. Ithuluzi lizobonisa inani le-Control / Set Point kusibonisi esiphansi kanye ne-Process Value ekubonisweni okuphezulu.

Ukusebenza Okubalulekile

• Ngokucindezela inkinobho ye-PRG, Yemodi Yokuhlela.
• Ngokucindezela inani likakhiye elithi UP/DN lingashintshwa bese ucindezela u-Enter ukuze uthole inani eliguquliwe esitolo.

Ukudluliswa Komsebenzi

• I-Relay: Dlulisela emuva uma Ukugeleza kungaphansi kwe-Set value & VULIWE lapho Ukugeleza kungaphezu kuka-Setha inani futhi ngokuphambene nalokho.

Ungawakhetha kanjani amapharamitha:

1st Cindezela okuthi Prgkey amasekhondi angu-3 ukuze ubonise ipharamitha yokokufaka kulepharamitha umsebenzisi angakhetha noma yikuphi okokufaka okukodwa bese ucindezela u-Ekey ukuze uthole amapharamitha alandelayo sebenzisa ukhiye kanye nepharamitha eqhubekayo yokusebenzisa imbongolo. Abasebenzisi bangakhetha noma iyiphi ipharamitha ngokusebenzisa upkey/imbongolo. Phuma Ipharamitha, kule pharamitha, uma ucindezela ukhiye u-E bese uphuma kumodi yokuhlela.

INDLELA YOKULAWULA PID

Kule modi sebenzisa amapharamitha alandelayo:

1. Uhlobo = PID
2. ply = Isikhathi sokulibaziseka se-Pid (inani elingu-1 = 1MS)
3. Ukusetshenziswa kwepharamitha yesenzo yesenzo se-PID esiya phambili/imodi ye-Revere
4. SP– = PID iphoyinti lokusetha.
5. dEtd = Inani lokuphuma kokunye lesenzo sokulawula se-PID sihamba kancane/ngokushesha(0-3000).
6. I-Intr: inani eliphelele le-PID Control (0-3000).
7. I-Pd– : Inani lenzuzo elilinganiselwe le-PID Setpoint(0-999.0)
8. dbnd : ibhendi efile % inani le-Setpoint(ibhendi efile= iphoyinti lesethi x dbnd%)

Ngesenzo esisheshayo sokulawula i-PID: bese ukhuphula inani elibalulekile futhi wehlise inani lokuphuma kokunye futhi ulungise inani lenzuzo elinganiselwe. Ngesenzo esinensayo Sokulawula kwe-PID: lungisa (ukhuphule) inani lokuphuma kokunye & wehlise inani elibalulekile futhi ulungise inzuzo elinganiselwe nevelu ephuma kokunye.

ibhande:
Kuleli pharamitha, iphesentitagUhlangothi oluphezulu noluphansi lwephoyinti elimisiwe luchazwa ukuze kuthi lapho i-PID ifinyelela inani lenqubo elizungeze iphuzu elimisiwe, ibhande elifile lingena esenzweni ngaleso sikhathi futhi okuyinani lebhande elifile uma inani lenqubo lingaphakathi kwalokho. umkhawulo. Ngakho-ke ngeke kube khona isenzo ekulawuleni. Futhi uma inani lenqubo lingaphezu kwenani lebhendi efile khona-ke isenzo sokulawula i-PID sizokwenzeka ngaphandle kwalokho akukho sinyathelo esizothathwa ngenxa yokuba sebhandeni elifile.
SP–: Kumodi esebenzayo, uma umsebenzisi ecindezela upkey + Prgkey bese ubonisa iphuzu lokusetha cindezela u-Ekey bese usetha inani olifunayo ngokusebenzisa phezulu/imbongolo bese ucindezela u-Ekey.
Imodi ye-Auto/Manual: Qala ubambe ukhiye wokufaka bese ucindezela ukhiye we-prg ngemuva kwalokho ithuluzi lizongena ngokuzenzakalelayo kumodi ye-manual / auto. Uma ngaphambili ikumodi ye-AUTO izohamba ngemodi yezandla futhi uma ikumodi yezandla izohamba ngemodi ye-AUTO.

Okuzenzakalelayo/Ngesandla: Ngokucindezela nokukhulula ukhiye wokungena, umsebenzisi angabheka ukuthi ithuluzi likumodi ezenzakalelayo noma imodi eyenziwa ngesandla.

Bonisa: kupharamitha yokubonisa, umsebenzisi angachaza ukuthi uyafuna yini ukukhombisa inani lephoyinti elimisiwe kusibonisi se-SV noma abonise inani lokulawula le-PID. Uma ukhetha okwethu bese ubonisa ukuphuma kokulawula kwe-pid noma uma ukhetha i-SETP bese ubonisa inani lephoyinti le-PID.
Inkomba Yenqubo ye-cum Controller(Imodi2): Kule modi umsebenzisi angasebenzisa ithuluzi njengenkomba/isilawuli senqubo futhi athathe okukhiphayo kokudlulisela kabusha okungu-4-20mA.

I-K-factor: Le-K-factor izonikezwa ngokwenani lama-pulses akhiqizwa inzwa/imitha ngokugeleza kwevolumu enikeziwe. (isb) 150 ukushaya ilitha njll. Le-K-factor yinani elifakwa kumitha yenqwaba noma inkomba/ithothaliza ukuze kufundwe kumayunithi wobunjiniyela.

Example 1: Uma isibonisi esikumitha yesilinganiso sokugeleza sidingeka ngamagaloni ase-US ngomzuzwana, futhi i-K-factor yemitha yokugeleza ingamaphazili angu-210 ngegaloni ngalinye lase-US, khona-ke i-K-factor efakwe kumitha yesilinganiso ingaba ngu-210. Uma ithothaliza ehlotshaniswa nayo ngemitha yokugeleza efanayo kwakumele imiswe ukuze izinga lokugeleza libe ngamagaloni ase-US inkomba ye-K-factor izoba ngu-210. Uma inkomba yayizosethelwa izinga lokugeleza kwengxenye yeshumi yegalani i-K-factor izoba ngu-210 / 10 = 21, 21=K-factor
Qaphela: Uma umsebenzisi edinga ukugeleza ivelu kokushumi kwegallon/Litre inani le-K factor = 21 limiswe kupharamitha yesici kanye nephoyinti le-k_decimal lisetha uziro. Uma umsebenzisi edinga ukukhombisa inani lokugeleza kokukodwa kusho ukuthi inani elingu-210 lisethwa kupharamitha yesici kanye no-k_decimal =0 .

Inothi le-K-factor: Cindezela ukhiye we-Prg ukuze ubonise ipharamitha yokufaka cindezela ukhiye u-E bese ukhetha okhiye be-puls ngokuthi up( )/dn( )okhiye ngemva kokukhetha cindezela ukhiye manje futhi ukuze ubonise okokufaka manje sebenzisa ukhiye wokukhetha ipharamitha elandelayo Fctr(factor) cindezela Manje i-Ekey ibonisa inani lokugcina elilayishiwe le-k_factor,Uma ufuna ukushintsha inani sebenzisa phezulu/Imbongolo ngokwenani lakho le-k_factor (Njenge-225/22.5) manje cindezela futhi ubambe i-Prgkey ngemva kwesekhondi elingu-1 cindezela
Ukhiye u-E manje ukhipha bobabili okhiye bese ubonisa i-dP(Iphoyinti leDesimali) Cindezela okuthi Ekey setha iphoyinti ledesimali ngokwenani lakho le-k_factor bese ucindezela u-Ekey manje uphinde ubonise okuthi Fctr (kusho ukuthi inani le-K-factor ligciniwe).
Example: Uma u-225 pulse = 1ltr/imizuzu ukugeleza Uma umsebenzisi edinga ukukhombisa inani lokugeleza kokushumi kweLitha bese u-225/10 = 22.5 1 st k_factor value(225) usetha kupharamitha yesici ngokusebenzisa up/imbongolo bese ucindezela & ubambe Prgkey ngemva kwalokho. Isekhondi elingu-1 cindezela u-Ekey bese ukhulula zombili izinkinobho manje Ipharamitha ye-DP izovela esibonisini Cindezela u-Ekey bese usetha indawo yephoyinti ledesimali ngokusebenzisa phezulu/Imbongolo bese ucindezela u-Ekey.
