Ngophuculo lwemithetho eqhubekayo nechanekileyo yolawulo lokuqinisekisa i-metrological yezinto ezikrwada, ngakumbi izinto eziqinileyo, kuyo yonke inkqubo yemveliso yefektri, kwaye ngeminyaka yoo-1990, kwadalwa uhlobo olutsha lwezixhobo zokuqinisekisa i-metrological ezinokuthathela ingqalelo imimiselo. .——multihead weigher (IsiNgesi Loss-in-weight). Isilinganisi se-multihead sisekwe kutshintsho lobunzima bobunzima bezinto ezikrwada kumzimba wesikali ukwenza umlinganiselo oqhubekayo kunye nochanekileyo kunye nokuqinisekiswa kwezinto eziluhlaza. Ukuvela kwe-multihead weigher ngokuthe ngcembe kuthathe indawo ye-original belt scale, i-spiral scale, kunye ne-accumulation scale, njengomlinganiselo omtsha ophuculweyo. amandla efiber. I-1 ye-multihead weigher (njengoko kubonisiwe kwi-Figure 1) Umfanekiso we-1 we-Mettler·I-multihead weigher ye-Toledo iquka iqonga lokulinganisa (i-sensor igxininiswe kwisiseko seqonga), i-motor variable frequency motor (enokuthi iqhube ngakumbi i-screw yezothutho kunye nokuxuba okuthe tye), umgqomo wokutyisa, ukuxuba ngokuthe nkqo, kunye nokuhamba kombane. Iqulunqwe ludibaniso oluthambileyo kunye nesixhobo sokulawula i-weigher ye-multihead (IND560CF).

Ukugqiba umlinganiselo oqhubekayo kunye nomsebenzi wokuqinisekisa, intsimi kufuneka ixhotyiswe nge-hopper enkulu, ivalve yesango ezenzekelayo (umsebenzi kukugcwalisa ngokuqhubekayo i-silo yokutya ye-multihead weigher), kunye nezixhobo zokufumana (umsebenzi kukwamkela ngokuqhubekayo. I-multihead weigher feeding), njl. njl. umzimba ukuya kwisixhobo sokulawula i-weigher ye-multihead (isixhobo sokulawula iSisisombululo esingundoqo se-multihead weigher, yonke imisebenzi yokukhwabanisa kunye nesisombululo iqhutywe yiyo), isixhobo sokulawula sibala i-coefficient ye-net elasticity ye-coefficient yokulinganisa umzimba ngexesha leyunithi nganye. njengokuhamba okupheleleyo okuthe ngqo kwangoko ngokwesiginali yedatha, kwaye emva koko ithelekise kunye neseti Ukuhamba okujoliswe kuko konke kuphuhlisiwe. Emva kokuba ubalo lwe-PID luqhutywe, umqondiso wedatha ohambayo ngoku we-4-50mA uphunyezwa ukutshintsha i-frequency yemveliso ye-starter ethambileyo yemoto yokutya, emva koko umlinganiselo wesantya semoto utshintshwa ukwenza isixa esithile sokutya njengoko. kufutshane neseti iyonke kangangoko kunokwenzeka. Ukuqukuqela okupheleleyo okujoliswe kuko, ukuze kuphunyezwe injongo yokondla okuchanekileyo. Ukuze ugqibezele ukondla ngokuqhubekayo kwe-multihead weigher kunye nokuchaneka kokuqinisekiswa komlinganiselo, umphezulu we-silo yokutya kufuneka uxhotyiswe nge-hopper enkulu engakwazi ukuqhubeka ukondla izinto kunye ne-valve yesango ezenzekelayo ngokupheleleyo ukulawula ukutya.

Kwisixhobo solawulo, misela ixabiso elingaphezulu lomda wokuzaliswa kwakhona (Refill_Stop) kunye nexabiso eliphantsi lokuzaliswa kwakhona (Refill_Star). Xa isixhobo sokulawula silinganisa ubunzima bobunzima kwisikali ukufikelela kwixabiso eliphantsi lomda wokuzaliswa kwakhona, ixabiso elivulekileyo lokuzaliswa kwakhona liya kuthunyelwa. Isiginali yedatha yevalve yesango yenza ukuba ivalve yesango ivuleke, izinto ezikrwada zehopper enkulu ziya kufakwa kumgqomo wokutyisa ngokonxibelelwano oluthambileyo oluqhubayo, kwaye ubunzima bomnatha kumzimba wesikali buya kwanda. Xa ixabiso lomda lifikelelwe, isibonakaliso sedatha yokuvala ivalve yesango iya kuthunyelwa ngaphandle ukwenza ivalve yesango ivale. Kuyo yonke le nkqubo, imotor yokondla ibisebenza, ngamanye amazwi, ukondla kuyaqhubeka. Kwezi zixhobo eziluhlaza ezinokujikeleza okungahambi kakuhle, zilula kwaye zincinci, ngexesha elifutshane emva kokuba ivalve yesango ivaliwe, inxalenye yobunzima bomnatha ayiyi kongezwa kumzimba wesikali. Ngeli xesha, ukuba i-weigher ye-multihead iphuhliswa ngokuhambelana nesignali yedatha ehanjiswa yinzwa Ukuba ulawulo lwe-PID luphumelele, kuba utshintsho lobunzima bomnatha oluvakaliswa yinzwa luya kuncitshiswa kolu luhlu lwexesha, oluya kubangela ukuba uphawu lwedatha lube yimpumelelo. ulahlekelwe isakhelo kwaye uthintele ukusebenza, ngoko ke ixesha lokutyisa (i-Timer2) likwamiselwe kwisixhobo solawulo, esikuko Ukuvala ivalve yesango iqalise ixesha.

Ekuqaleni kokuzaliswa, kulindeleke ukuba ixesha lokutya liza kuphela. Ngeli xesha, i-motor yokutya iya kugcina i-frequency ngaphambi kokutya kwaye ayiyi kutshintsha. Ngamanye amazwi, i-multihead weigher ikwi-frequency esisigxina ngexesha lenkqubo yonke. Ukusebenza—Ukuguqulwa kwedatha engatshintshiyo. Xa ixesha lokutya liphelile, i-multihead weigher ibuyisela ngokuzenzekelayo ulawulo lwexesha langempela, oko kukuthi, ilawula i-motor yokondla ngokwesignali yedatha ehanjiswa yinzwa.
