Umbhali: Smartweigh– Isisindo Sezinhloko Eziningi

Ngokuthuthukiswa kwemithethonqubo yokulawula ukuqinisekiswa kwe-metrological okuqhubekayo nokunembile kwezinto zokusetshenziswa, ikakhulukazi izinto zokusetshenziswa eziqinile, uhlobo olusha lwemishini yokuqinisekisa i-metrological——Imishini nemishini yokuqinisekisa i-metrological yesimo esingenasisindo yaqala ukuba khona ngawo-1990. I-multihead weiger ilinganisa ngokuqhubekayo nangokunembile izinto zokusetshenziswa ngokuya ngoshintsho esisindweni se-net yezinto zokusetshenziswa emzimbeni wesikali. Ukuvela kwe-multihead weiger kancane kancane kwathatha indawo yesilinganiso sebhande le-elekthronikhi lokuqala, isikali esijikelezayo kanye nesikali esiphelele.

Njengendlela entsha nethuthukisiwe yokulinganisa, isetshenziswe kabanzi embonini yensimbi, yezimayini, yezitshalo zamakhemikhali kanye nemboni yamandla e-fiber yamakhemikhali. Ipulatifomu yesevisi yokulinganisa, ibhini lokudla kanye nayo yonke imishini nemishini esebenza epulatifomu yesevisi yokulinganisa isetshenziswa njengomzimba wonke wokulinganisa, futhi inzwa idlulisela njalo ushintsho lwesisindo esiphelele emzimbeni wokulinganisa ku-manipulator yesisindo samakhanda amaningi (i-manipulator iyisihluthulelo se-multihead weigher Ingxenye yesisombululo, konke ukuphathwa kanye nesisombululo kwenziwa yiyo). Ithuluzi lokulawula libala i-coefficient yesisindo esiphelele yomzimba wesikali ngesikhathi seyunithi ngokuya ngesignali yedatha njengokugeleza okuphelele okusheshayo, bese liqhathanisa nokugeleza okuphelele okuqondiwe.

Ngemva kokubala i-PID, isignali yedatha yamanje yokukhipha engu-4-50mA, shintsha imvamisa yokukhipha ye-inverter yemoto yokudla, bese ushintsha isilinganiso sejubane lemoto, ukuze inani elithile lokudla lisondele ngangokunokwenzeka ekugelezeni okuphelele okuqondiwe, ukuze kufezwe indawo enembile yokuphakelwa. Ukuze kuqedwe kangcono ukunemba kokuqinisekisa kokudla okuqhubekayo kanye nokulinganisa kwesisindo se-multihead, i-hopper enkulu yokondla okuqhubekayo kanye ne-valve ezenzakalelayo ngokuphelele yokondla ukudla kumele kubekwe ebhinini lokudla. Kukhona inani elingaphezulu lomkhawulo (recharge_terminated) kanye nenani eliphansi lomkhawulo (recharge_started) kumitha yokulawula.

Uma isisindo esiphelele esikalini sifinyelela inani eliphansi lomkhawulo, kuzothunyelwa isignali yokuvula ivalvu yokulayisha kabusha, ivalvu yokulayisha kabusha izovulwa, izinto zokusetshenziswa ezigcinwe esitokweni zizokwehliswa ziyiswe ebhanini lokulayisha ngokuya ngokuxhumeka okuguquguqukayo okuqhubayo, futhi isisindo esiphelele esikalini sizokhula. Uma isisindo esiphelele esikalini sifinyelela inani lokulayisha kabusha elibekiwe, lapha kuyo yonke inqubo, imoto yokudlulisa isebenza kusukela ekuqaleni kuze kube sekupheleni, okusho ukuthi iphasi liyaqhubeka. Ngezinto zokusetshenziswa ezinokujikeleza kwegazi okubi, isisindo esilula nesisindo esilula, akulula ukwengeza ingxenye yesisindo esiphelele emzimbeni wesikali esikhathini esifushane ngemuva kokuba ivalvu yesango ivaliwe.

Ngalesi sikhathi, uma isikali samakhanda amaningi senza ukulawula kwe-PID ngokuya ngesignali yedatha edluliswa yinzwa, ushintsho lwesisindo olutholwe yinzwa phakathi nalesi sikhathi luzoncishiswa, okuholela ekuguqulweni kohlaka lokulahlekelwa kwesignali yedatha okungalungile. Ngakho-ke, kukhona nokubambezeleka kwesikhathi sokuphakelwa (isibali sikhathi 2) ethuluzini lokulawula, eliqala ukubala isikhathi kusukela ekuvalweni kwevalvu yesango. Phakathi nesikhathi kusukela ekuqaleni kokuphakelwa kuze kube sekupheleni kokulibaziseka kwesikhathi sokuphakelwa, imoto yokudla izogcina imvamisa ngaphambi kokuphakelwa, okungukuthi, isikali samakhanda amaningi sisebenza ngemvamisa ehleliwe - ukuphathwa kwedatha engaguquki.

Uma isikhathi sokudla sesiphelile, isikali samakhanda amaningi sibuyisela ngokuzenzakalelayo ukulawula kwesikhathi sangempela, okungukuthi, sisebenzisa injini yokudla ngokwesignali yedatha ethunyelwe yinzwa. Inqubo yokusebenza yesikali samakhanda amaningi yenziwa ngale ndlela. Ukuze kuqinisekiswe kangcono ukulingana kwesikali samakhanda amaningi, ngaphezu kwamapharamitha ayinhloko ayinhloko, kukhona namapharamitha alandelayo ayinhloko kuthuluzi lokulawula: I-SetP (inani le-p elilinganayo); inani lesikhathi sokuhlanganiswa; I-SetD (inani lesignali ehlukile isikhathi d); I-Caltime (isikhathi sokusampula ukugeleza okuphelele kwamanje); I-Calcount (isikhathi sokusampula ukugeleza okuphelele kwamanje); ithagethi yokuqapha ukugeleza; umkhawulo u-E (ububanzi bokuphambuka obubekezelelekayo bokuqapha ukugeleza); isisindo se-high_net (inani lezinga lezinto ezibonakalayo eliphezulu); isisindo_esiphansi (inani eliphakathi lomthwalo-eliphezulu (umkhawulo wemvamisa); inani eliphansi lomthwalo (imvamisa encane); ukugeleza kwesamba sesampula 1 (inani eliphakathi lokulungiswa kwe-dynamic 1); ukugeleza kwesamba sesampula 2 (inani eliphakathi lokulungiswa kwesamba se-dynamic 2); ukugeleza kwesamba sesampula 3 (inani eliphakathi lokulungiswa kwesamba se-dynamic 3); imodi yokusebenza (ukukhetha imodi yokusebenza); ukukhetha isisindo (ibhetshi elikhulu (ukuhlaziywa kwenani) ukukhethwa komsebenzi); i-flow coefficient (ipharamitha eyinhloko yokulinganisa ukugeleza kwesamba); Isici sesilinganiso (ipharamitha eyinhloko yokulinganisa isilinganiso sezinto zokusetshenziswa).
