Umbhali: Smartweigh– Isisindo Sezinhloko Eziningi

Ngokuthuthukiswa kwemithethonqubo yokulawula ukuqinisekiswa kwe-metrological okuqhubekayo nokunembile kwezinto zokusetshenziswa, ikakhulukazi izinto zokusetshenziswa eziqinile, kuyo yonke inqubo yokukhiqiza izimboni, kanye neminyaka yama-1990, kwadalwa uhlobo olusha lwemishini yokuqinisekisa i-metrological engacabangela imithethonqubo.——i-multihead weiger (i-English Loss-in-weight). I-multihead weiger isekelwe ekushintsheni kwesisindo esiphelele sezinto zokusetshenziswa emzimbeni wesikali ukuze kwenziwe ukulinganisa okuqhubekayo nokunembile kanye nokuqinisekiswa kwezinto zokusetshenziswa. Ukuvela kwe-multihead weiger kwathatha kancane kancane isikali sebhande le-elekthronikhi lokuqala, isikali esijikelezayo, ngisho nesikali sokuqongelela, njengesilinganiso esisha esithuthukisiwe. Indlela yokuqinisekisa isetshenziswa kabanzi emikhakheni ye-metallurgy, izimayini, izitshalo zamakhemikhali, kanye namandla e-fiber yamakhemikhali. I-1multihead weiger (njengoba kuboniswe kuMfanekiso 1) Isibalo 1 se-Mettler·I-multihead weiger kaToledo iqukethe ipulatifomu yokulinganisa (inzwa iqiniswe esisekelweni sepulatifomu yokulinganisa), imoto yemvamisa eguquguqukayo yokudla (engashayela futhi isikulufu sokuthutha kanye nokuxuba okuvundlile), ibhini lokudla, ukuxuba okuqondile, kanye nokuqhuba kukagesi. Yakhiwe ngoxhumano oluthambile kanye nethuluzi lokulawula isisindo samakhanda amaningi (IND560CF).

Ukuze kuqedwe umsebenzi wokulinganisa nokuqinisekisa okuqhubekayo, insimu kumele ifakwe ne-hopper enkulu, i-valve yesango ezenzakalelayo ngokuphelele (umsebenzi uwukugcwalisa njalo isilo sokudla esinobunzima obunamakhanda amaningi), kanye nemishini yokwamukela (umsebenzi uwukwamukela njalo ukudla okunobunzima obunamakhanda amaningi), njll. 2 Umdwebo webhlokhi yokusebenza 3 Isimiso Ipulatifomu yokukala, ibhini lokuphakela kanye nayo yonke imishini nemishini esebenza epulatifomu yokukala kusetshenziswa njengomzimba wonke wesikali, futhi inzwa idlulisela njalo ushintsho lwesisindo esiphelele emzimbeni wesikali kuthuluzi lokulawula lesikali esinamakhanda amaningi (ithuluzi lokulawula liyingxenye yesisombululo esiyinhloko sesikali esinamakhanda amaningi, yonke imisebenzi yokuphatha kanye nesixazululo yenziwa yiyo), ithuluzi lokulawula libala i-coefficient yesisindo esiphelele yomzimba wesikali ngesikhathi seyunithi njengokugeleza okuphelele okusheshayo ngokusho kwesignali yedatha, bese liqhathanisa nesethi. Ukugeleza okuphelele kwenani eliqondiwe kuthuthukisiwe ngokulinganisela. Ngemva kokubalwa kwe-PID, isignali yedatha yokugeleza kwamanje engu-4-50mA iyakhishwa ukushintsha imvamisa yokuphuma kwesiqalo esithambile semoto yokondla, bese isilinganiso sejubane semoto sishintshwa ukuze kwenziwe inani lokuphakela elithile lisondele kakhulu kusethi iyonke ngangokunokwenzeka. Ukugeleza okuphelele okuqondiwe, ukuze kufezwe injongo yokondla okunembile. Ukuze kuqedwe ukondla okuqhubekayo kwe-multihead weiger kanye nokunemba kokuqinisekiswa kokulinganisa, ingxenye ephezulu yesilo yokondla kumele ifakwe i-hopper enkulu engondla njalo impahla kanye ne-valve yesango ezenzakalelayo ngokuphelele ukulawula ukondla.

Kuthuluzi lokulawula, setha inani eliphezulu lomkhawulo wokugcwalisa kabusha (Refill_Stop) kanye nenani eliphansi lomkhawulo wokugcwalisa kabusha (Refill_Star). Lapho ithuluzi lokulawula likala isisindo esiphelele esikalini ukuze lifinyelele inani eliphansi lomkhawulo wokugcwalisa kabusha, inani elivulekile lomkhawulo wokugcwalisa kabusha lizothunyelwa. Isignali yedatha yevalvu yesango yenza ivalvu yesango ivuleke, izinto zokusetshenziswa ze-hopper enkulu zizofakwa ebhinini lokudla ngokuya ngokuxhumeka okuthambile okuqhubayo, futhi isisindo esiphelele emzimbeni wesikali sizokhula. Lapho inani lomkhawulo lifinyelelwa, isignali yedatha yokuvala ivalvu yesango izothunyelwa ukuze ivalvu yesango ivale. Kuyo yonke le nqubo, imoto yokudla ibilokhu isebenza, ngamanye amazwi, ukudla kuyaqhubeka. Kulezi zinto zokusetshenziswa ezinokujikeleza kwegazi okubi, okulula futhi okuncane, kungakapheli isikhathi esifushane ngemuva kokuba ivalvu yesango ivaliwe, ingxenye yesisindo esiphelele ngeke yengezwe emzimbeni wesikali. Ngalesi sikhathi, uma isisindo samakhanda amaningi sithuthukiswa ngokwesignali yedatha edluliswa yinzwa Uma ukulawulwa kwe-PID kuphumelele, ngoba ushintsho lwesisindo oluzwakala yinzwa luzoncishiswa kulesi sikhathi, okuzobangela ukuthi isignali yedatha ilahlekelwe uhlaka futhi kuvimbele ukusebenza, ngakho-ke isikhathi sokudla (i-Timer2) siphinde sisethwe kuthuluzi lokulawula, okuyi-valve yesango esanda kuqala ukubala isikhathi.

Ekuqaleni kokugcwalisa kabusha, kulindeleke ukuthi isikhathi sokudla siphele. Phakathi nalesi sikhathi, injini yokudla izogcina imvamisa ngaphambi kokudla futhi ngeke ishintshe. Ngamanye amazwi, isisindo samakhanda amaningi sisemvamisa eqondile phakathi nenqubo yonke. Ukusebenza—Ukuphathwa kwedatha okuqinile. Lapho isikhathi sokudla sesiphelile, isisindo samakhanda amaningi sibuyisela ngokuzenzakalelayo ukulawula kwesikhathi sangempela, okungukuthi, silawula injini yokudla ngokwesignali yedatha edluliswa yinzwa. Yonke inqubo yokusebenza kwesisindo samakhanda amaningi iphindwa ngale ndlela.

Ukuze kuqinisekiswe ukulingana kwesikali se-multihead, ngaphezu kwalezi zinhlaka eziyinhloko ezibalulwe ngenhla, kukhona futhi lezi zinhlaka ezilandelayo eziyinhloko kuthuluzi lokulawula: I-SetP (inani le-P elilinganiselwe); I-SetI (inani lesikhathi sokuhlanganiswa I); I-SetD (isikhathi sokwehluka) I-Caltime (isikhathi sokusampula ukugeleza okuphelele kwamanje); I-Calcount (imvamisa yokusampula ukugeleza okuphelele kwamanje); I-Target-F (ithagethi yokuqapha ukugeleza); Umkhawulo-E (ububanzi bokubekezelelana kokuqapha ukugeleza); I-Hig_Weight (inani lezinga lezinto ezibonakalayo eliphezulu)); I-Low_Weight (inani lezinga lezinto ezibonakalayo eliphansi); I-Load-Max (inani elicacisiwe lemvamisa); I-Load-Min (inani elincane lemvamisa); I-SampleFlux1 (inani lokugeleza okuphelele lokulinganisa eliguquguqukayo 1); I-SampleFlux2 (inani lokugeleza okuphelele lokulinganisa eliguquguqukayo 2); I-SampleFlux3 (inani lokugeleza okuphelele lokulinganisa eliguquguqukayo 3); I-WorkMode (ukukhetha imodi yomsebenzi); I-BatchSelect (inombolo yeqembu (ukuhlaziywa kobuningi) ukukhethwa kwendima); I-FluxFactor (ipharamitha eyinhloko yokulungiswa kokugeleza okuphelele); I-ProportionFactor (ipharamitha eyinhloko yokulungiswa kwesilinganiso sezinto ezingavuthiwe). 4 Inkinga evamile lapho kuklanywa isikali samakhanda amaningi ukuthuthukisa ukulingana kwesikali samakhanda amaningi.
