Ngokuthuthukiswa kwemithethonqubo eqhubekayo nenembile yokulawula ukuqinisekiswa kwe-metrological yezinto zokusetshenziswa, ikakhulukazi izinto zokusetshenziswa eziqinile, kuyo yonke inqubo yokukhiqizwa kwezimboni, futhi ngawo-1990, uhlobo olusha lwemishini yokuqinisekisa i-metrological engacabangela imithethonqubo yasungulwa. .——i-multihead weigher (English Loss-in-weight). Isikali se-multihead sisekelwe ekushintsheni kwesisindo sengqikithi yezinto ezingavuthiwe emzimbeni wesikali ukuze kwenziwe ukulinganisa okuqhubekayo nokunembile kanye nokuqinisekiswa kwezinto zokusetshenziswa. Ukuvela kwe-multihead weigher kancane kancane kwashintsha isikali sokuqala sebhande le-elekthronikhi, isikali esivunguzayo, ngisho nesilinganiso sokuqongelela, njengesikali esisha esithuthukisiwe Indlela yokuqinisekisa isetshenziswa kabanzi emkhakheni we-metallurgy, izimayini, izitshalo zamakhemikhali namakhemikhali. fiber energy. 1 i-multihead weigher (njengoba kukhonjisiwe kuMfanekiso 1) Umfanekiso 1 we-Mettler·I-multihead weigher ye-Toledo iqukethe iplathifomu yokukala (inzwa igxilwe kusisekelo seplathifomu), injini yefrikhwensi yokuphakelayo (engakwazi ngaphezu kwalokho ukushayela isikulufu sokuthutha nokuxutshwa okuvundlile), umgqomo wokuphakela, ukuhlanganisa okuqondile, kanye nokuhamba kukagesi. Yakhiwe ngoxhumano oluthambile kanye nethuluzi lokulawula isisindo se-multihead (IND560CF).

Ukuze uqedele ukulinganisa okuqhubekayo nokusebenza kokuqinisekisa, inkambu kufanele futhi ifakwe i-hopper enkulu, i-valve yesango ezenzakalelayo ngokugcwele (umsebenzi uwukugcwalisa ngokuqhubekayo isisele sokuphakelayo se-multihead), kanye nezinto zokwamukela (umsebenzi uwukwamukela ngokuqhubekayo. i-multihead weigher), njll. 2 Umdwebo webhulokhi yokusebenza 3 Iplathifomu yokukala Isimiso, umgqomo wokuphakelayo kanye nayo yonke imishini nemishini esebenza endaweni yokukala kusetshenziswa njengomzimba wonke wesikali, futhi inzwa idlulisa ngokuqhubekayo ukuguqulwa kwesisindo senetha esikalini. umzimba ukuya ethuluzini lokulawula isisindo se-multihead (ithuluzi lokulawula Ingxenye eyisihluthulelo yesixazululo se-multihead weigher, yonke imisebenzi yokukhohlisa nemisebenzi yesixazululo yenziwa yiyo), ithuluzi lokulawula libala i-net weight elasticity coefficient of the body scale time unit. njengokugeleza okuphelele okuqondile okuzenzakalelayo ngokwesiginali yedatha, bese iqhathanisa nesethi Ukugeleza okuphelele okuhlosiwe kuthuthukisiwe. Ngemuva kokuthi senziwe ukubala kwe-PID, isiginali yedatha yokugeleza yamanje ye-4-50mA iyaphuma ukuze kushintshwe imvamisa yokuphuma kwesiqalisi esithambile semoto yokuphakela, bese isilinganiso sesivinini semoto sishintshwa ukwenza inani elithile lokuphakela njenge. eduze kwesethi yonke ngangokunokwenzeka. Ukugeleza okuphelele okuhlosiwe, ukuze kuzuzwe inhloso yokondla okunembile. Ukuze uqedele ukuphakelwa okuqhubekayo kwe-multihead weigher kanye nokunemba kokuqinisekisa ukulinganisa, phezulu kwesisele sokuphakelayo kufanele kufakwe i-hopper enkulu ekwazi ngokuqhubekayo ukondla impahla kanye ne-valve yesango ezenzakalelayo ngokuphelele ukulawula ukuphakela.

Kuthuluzi lokulawula, setha inani eliphezulu lomkhawulo lokugcwaliswa kabusha (Refill_Stop) kanye nenani eliphansi lomkhawulo lokugcwaliswa kabusha (Refill_Star). Uma ithuluzi lokulawula likala isisindo sengqikithi esikalini ukuze lifinyelele inani eliphansi lomkhawulo lokugcwaliswa, inani elivulekile lomkhawulo wokugcwalisa lizothunyelwa. Isignali yedatha ye-valve yesango yenza i-valve yesango ivuleke, impahla eluhlaza ye-hopper enkulu izofakwa emgqonyeni wokuphakela ngokuya ngoxhumano oluthambile lwe-conductive, futhi isisindo senetha emzimbeni wesikali sizokhula. Lapho inani lomkhawulo lifinyelelwa, isignali yedatha yokuvala i-valve yesango izothunyelwa ukuze kuvalwe i-valve yesango. Kuyo yonke le nqubo, injini yokudla ibisebenza, ngamanye amazwi, ukuphakela kuyaqhubeka. Kulezi zinto ezisetshenziswayo ezinokujikeleza okungalungile, ukukhanya kuqhathaniswa futhi kuncane kakhulu, kungakapheli isikhathi esifushane ngemuva kokuvalwa kwe-valve yesango, ingxenye yesisindo senetha ngeke yengezwe emzimbeni wesikali. Ngalesi sikhathi, uma i-weigher ye-multihead ithuthukiswa ngokusho kwesignali yedatha edluliswa inzwa ulahlekelwe uhlaka futhi uvimbele ukusebenza, ngakho-ke isikhathi sokuphakela (I-Timer2) siphinde simiswe ethuluzini lokulawula, okuwukuthi Ukuvala i-valve yesango isanda kuqalisa isikhathi.

Ekuqaleni kokugcwalisa, kulindeleke ukuthi isikhathi sokudla sizophela. Ngalesi sikhathi, i-motor yokudla izogcina imvamisa ngaphambi kokuphakela futhi ngeke ishintshe. Ngamanye amazwi, isikali se-multihead sisesimweni esinqunyiwe phakathi nayo yonke inqubo. Ukusebenza—Ukukhohlisa kwedatha okungashintshi. Lapho isikhathi sokudla sesiphelile, i-multihead weigher ibuyisela ngokuzenzakalelayo ukulawulwa kwesikhathi sangempela, okungukuthi, ilawula i-motor yokuphakelayo ngokusho kwesignali yedatha ehanjiswa inzwa. Yonke inqubo yokusebenza kwe-multihead weigher iphindaphindiwe ngale ndlela.

Ukuze kuqinisekiswe umugqa wesisindo se-multihead, ngaphezu kwalezi mingcele eziyinhloko ezishiwo ngenhla, kukhona nemingcele eyinhloko elandelayo kuthuluzi lokulawula: I-SetP (inani le-proportional coefficient P); I-SetI (isikhathi sokuhlanganisa ngiyasazisa); I-SetD (isikhathi esihlukile) Isikhathi se-Caltime (isikhathi samanje sokugeleza kwesampula); Ukubala (ingqikithi yamanje yesampula yokugeleza kwemvamisa); Ithagethi-F (ithagethi yokuqapha ukugeleza); I-Limit-E (ibanga lokubekezelela ukugeleza kokuqapha); I-Hig_Weight (inani eliphezulu lezinto ezibonakalayo) ); Isisindo Esiphansi (inani lempahla ephansi); Load-Max (ivelu eshiwo imvamisa); I-Load-Min (inani elincane lemvamisa); I-SampleFlux1 (inani lokugeleza eliphelele lokulinganisa okuguquguqukayo 1); I-SampleFlux2 (inani lokugeleza eliphelele lokulinganisa okuguquguqukayo 2); I-SampleFlux3 (inani lokugeleza eliphelele lokulinganiswa kwe-3); Imodi Yokusebenza (ukukhethwa kwemodi yomsebenzi); I-BatchSelect (inombolo yeqoqo (ukuhlaziywa kobuningi) ukukhetha indima); I-FluxFactor (ingqikithi yokulungiswa kokugeleza kwemingcele eyinhloko); I-ProportionFactor (imingcele eyinhloko yokulungiswa kwesilinganiso sempahla eluhlaza). 4 Inkinga evamile lapho uklama i-multihead weigher ukuthuthukisa umugqa wesisindo se-multihead.
