Umbhali: Smartweigh–I-Multihead Weighter

Ukuthuthukiswa kobuchwepheshe kokuqinisekiswa kwe-rotary metrological kanye nomgomo wayo we-multihead weigher 1. Isimo samanje sendlela yokuqinisekisa i-metrological yemishini yokuxuba ejikelezayo 1.1 Indlela yokuqinisekisa ye-rotary metrological yendabuko isetshenziswa ekuqinisekisweni kwe-metrological yempahla eluhlaza ye-fibrous njengempahla yokwakha yokuhlobisa, okusanhlamvu. , uwoyela, ukudla, izimayini, njll., noma uma ukhohlisa izinongo ku-inthanethi. . Okujwayelekile kakhulu yilezi: izikali zamabhande e-electronic, ama-flushing plate flowmeters, izikali zenuzi, nezikali zokuphakela amasondo ayindilinga. Le ndlela yokuqinisekisa ukulinganisa inezici zayo, kodwa imikhawulo mikhulu kakhulu.

Ubuchwepheshe bokucutshungulwa kwesikali sebhande le-elekthronikhi kwethulwa ngokuningiliziwe, futhi izinyathelo zimi kanje: Isikali sebhande le-elekthronikhi sihlanganisa isiginali yedatha yomthwalo kanye nezinga lokuguqulwa (isilinganiso sejubane lebhande lokudlulisa) isiginali yedatha endaweni ephelele yebhizinisi. (isigaba sesisindo) ukuze uthole inani lokugeleza eliphelele. Okuqondiwe okusebenzisekayo. Ukwethulwa okuningiliziwe kobuchwepheshe bokucutshungulwa kwesikali sebhande le-elekthronikhi Qaphela: Inani lezinto ezingavuthiwe okufanele zikhishwe lishintshwa ngokuya ngesilinganiso sesivinini sebhande lokudlulisa ukudonsa nokudonsa. Usayizi, umthwalo ebhandeni lokushayela uzinzile. Uma kuqhathaniswa nezinye izindlela zokuphakela, le ndlela inomphumela omuhle wangempela wokuqinisekiswa kwe-metrological kanye nomugqa.

Umdwebo wohlelo wesekethe yokuqinisekisa ukulinganisa yesikali sebhande le-elekthronikhi Qaphela: Imisebenzi yokuphakela neyokukala iqedwa ngamabhande amabili okudlulisela ngokulandelana. 1.2 Indlela yokuqinisekisa ukulinganisa kwe-rotary isetshenziswa emshinini wokuxuba oqhubekayo. izinto zokusebenza, i-concrete rotary mixer, i-bitumen rotary mixer. Ngokuphathelene nokunemba kokuqinisekiswa kwe-metrological, kulesi sigaba, lolu hlobo lwesisetshenziswa alukwazi ukwenziwa olujwayelekile ngezikhathi ezithile. Ngakho-ke, indlela yokuxuba i-rotary ayithandwa ngamakhasimende amaningi, okungenye yezizathu.

Imibukiso yesayensi ingabonisa ukuthi izinqubo zokuxuba nokucubungula ezinqunywe yilezi zindlela ezimbili zokuqinisekisa ukulinganisa zinezindawo zazo ezisebenzisekayo, futhi ukusetshenziswa kokuxuba okujikelezayo akufanele kubekwe engcupheni imikhawulo yesikhashana yobuchwepheshe. Kulesi sigaba, ezweni lakithi, imishini yokuxuba ejikelezayo yonke ikalwa ngendlela yevolumu noma isikali sebhande le-elekthronikhi/isikali esivunguzayo. Ngawo-1970, ubuchwepheshe bokucubungula ukuxuba okuqhubekayo basungulwa kusukela eYurophu ukuze kuthuthukiswe futhi kuklanywe. Kuze kube manje, sekunje, futhi akukho ngcono kusukela ekuqaleni kuze kube sekugcineni. Eqinisweni, lezi zindlela ezimbili zokuqinisekisa ukulinganisa zingafinyelela ukunemba okuphezulu ezinhlelweni zokusebenza zase-Europe. Isibonelo, isikali se-batching sebhande lokudlulisa lika-Schenck e-France sinokunemba okuguquguqukayo kwesinongo okungu-2%.

Kodwa ezweni lami, akukuhle, ngoba kuncike ekuvinjweni kokukhiqizwa kwezimboni eziyisisekelo ezifana nokukhiqizwa kwemishini nemishini kanye nezinto zokusetshenziswa ezweni lami. Kulesi sigaba, ukulinganisa nokuqinisekisa ukunemba kwezikali zebhande le-elekthronikhi ezisetshenziswa emgwaqeni wezwe lakithi ngokuvamile zilinganiselwa ku-5% kuphela, okungehlukile ekuqinisekisweni kokulinganisa umthamo, futhi ukwethembeka kwesikhathi eside kubuthakathaka. ezimbili. Ngokuqhubekayo Ukala Izinguquko——Isisindo se-multihead (English Loss-in-weight) sesikali somuthi wesignali esihlukanisayo (isimo esingenasisindo) saqala ukusetshenziswa kuyo yonke inqubo yokukhiqizwa kwezimboni ngeminyaka yawo-1990 ukuze kuqinisekiswe i-metrological okuqhubekayo.

I-Multihead weigher kancane kancane ithatha indawo yezilinganiso zebhande le-electronic, izikali ezisonge, ngisho nezikali eziqongelelayo. Njengendlela yokuqinisekisa yokulinganisa entsha nethuthukisiwe, kancane kancane isetshenziswa ezintweni ezingavuthiwe ezengeziwe. 2.1 Umqondo oyisisekelo: Thatha ibhakede lokukala kanye nenhlangano yokudla njengomzimba wonke wesikali, ngokuqhubekayo isampula yesiginali yedatha yesisindo somzimba wesikali ngokuya ngephaneli yezinsimbi noma isofthiwe yekhompuyutha ephezulu, bese ukala isilinganiso soshintsho senetha. isisindo ngesikhathi seyunithi njengejubane elisheshayo Ukugeleza okuphelele, bese kuxazululwa ngokobuchwepheshe ngokuya ngobuchwepheshe bokuhlunga bezingxenyekazi zekhompuyutha ezihlukahlukene kanye nesofthiwe, kungasetshenziswa njengethagethi yokukhohlisa.“ukugeleza okuphelele okuqondile”. Ukutholwa kwalokhu kugeleza okuphelele kubaluleke kakhulu futhi kuyisisekelo sokulinganisa okunembile nokuqinisekiswa kwesisindo se-multihead.

Indlela yakudala ichazwa ngokuningiliziwe emfanekisweni: indlela yokuqinisekisa isikali se-multihead, bese i-FC ibuyisela i-algorithm yokwenza kahle ngokombono we-PID, yenza ukubalwa kokusebenza kokugeleza okuphelele eduze kwethagethi iyonke, kanye nemiphumela. isignali yedatha yokulungisa ukusebenzisa isiqalisi esithambile nezinye iziphakeli ezidlidlizayo. Iphaneli yokulawula. 2.2 Ukusetshenziswa okuqondile kwesilinganisi sesignali esihlukile se-multihead: Kusukela kumgomo oyisisekelo, kungabonakala ukuthi ngeke kulinyazwe izinguquko zemishini yomshini wokulinganisa kanye nesakhiwo sokuphakelayo. Ikala kuphela iphutha lesisindo sengqikithi (isisindo somehluko), futhi Uma iqhathaniswa nendlela yokuqinisekisa ye-metroloji eguquguqukayo evamile, izinzuzo zayo zisobala. Lapho okuqondiwe kokulawula kuwukugeleza okuphelele (t/h, kg/min), futhi impahla eluhlaza inokuthuthwa okuhle, futhi ukunemba kokuqinisekiswa kwe-metrological kudingeka ukuthi kube phezulu, indlela yesimo esingenasisindo ingasetshenziswa njengohlelo olungcono kakhulu lwe-metrological. ukuqinisekiswa.

2.2.2 Inqubo yokukhiqiza ye-multihead weigher: Inqubo yokukhiqiza ye-multihead weigher 2.2.3 Izindaba okufanele zinakwe esikimini sokuklama se-multihead weigher, izici ezithinta ukunemba: i-multihead weigher inezici zesikali sedatha esimile nesikali esiguqukayo. . Ngakho-ke, ohlelweni lokuklama Isofthiwe yesistimu, isho lokhu: 1. Ibanga elifanele lezinga lokuthutha ngokuvamile lingama-60% kuya ku-70% omthamo wokuthutha olinganiselwe emsebenzini othile. Uma kusetshenziswa ukuguqulwa kwesivinini sokuxhumana nokushintshanisa, kungcono ukuphendula imvamisa yokucindezeleka engu-35-40Hz. Lokhu kuqinisekisa uhla olubanzi lokulungisa.

Kuphinde kube ngenxa yokuthembeka okubi kwesofthiwe yesistimu lapho izinga lokuthutha liphansi kakhulu. 2. Ibanga lokulinganisa lenzwa limaphakathi. Ngamanye amazwi, inzwa futhi isebenzisa u-60% ~ 70% webanga layo lokulinganisa ngokuya ngefomula. Isignali yedatha inezinhlobonhlobo eziningi zokuguqulwa, okuzuzisa kakhulu ukuthuthukisa ukunemba. 3. Uhlelo lokuklama uhlelo lwemishini kufanele luqinisekise ukuthi izinto zokusetshenziswa zihamba kahle, futhi liqinisekise ukuthi isikhathi sokudla sifushane, futhi ukuphakelwa akufanele kuvame kakhulu. Ngokuvamile, kunqunywa ukuthi ukuphakelwa kufanele kwenziwe njalo ngemizuzu emi-5-10.

Ithuluzi lokudlulisela lezinsiza ezisekelayo kufanele liqinisekise ukusebenza okuzinzile kanye nokuma okuhle komugqa. 2.2.4 Ithemba lokufaka isicelo: Ngokuthuthuka okusheshayo kwesistimu yokulawula idivayisi ye-elekthronikhi, isikali se-multihead sisekelwe ekukhethweni kobuchwepheshe obusha, futhi ukunemba kokuqinisekiswa kwe-metrological kunyuswa kusuka ku-0.3% kuya ku-0.5%. Isihluthulelo salobu buchwepheshe obusha ukusetshenziswa kwezinzwa zesisindo sokuboniswa kwedijithali.

2.2.4.1 Ukusetshenziswa kwenzwa yesisindo sombukiso wedijithali: Ukuze kuhlanganiswe kangcono esidingweni sokulinganisa okuguquguqukayo nokunembile, kubaluleke kakhulu ukuthi kusetshenziswe njengenzwa yokhiye wohlelo lwesofthiwe ekukaleni impahla. Ikakhulukazi endaweni lapho uhlelo kufanele luhlakaniphe khona, idatha esheshayo noma engaqondile yenzwa ibalulekile. Ngalesi sikhathi, ukungaqiniseki kokulinganisa okunembile kanye nezinga lokulinganisa elinembile ngokuvamile kuyipheya yomehluko, futhi kunzima ukucabangela kokubili. Isimo esithile sikhethwa njengokuvumelana. Embonini yokukala, izinzwa eziningi ze-analog zedijithali zendabuko ziyakhiqizwa futhi zisetshenziswe ezweni lami kulesi sigaba, futhi ukukhishwa kwesignali ye-pulse kuncane.

Ukuthatha inzwa yesisindo esinomphumela omkhulu ophelele kanye nesimiso esiyisisekelo samandla okumelana ne-resistor njengesibonelo, okukhiphayo okukhulu okujwayelekile kungu-30-40mV. Ngakho-ke, isignali yedatha ithintwa kalula ifrikhwensi yomsakazo, futhi ibanga lokudlulisela lekhebula nalo lifushane, ngokuvamile phakathi kwamamitha ayishumi. Emshinini wokukala isisindo sesitsha (isikali se-silo batching scale), ipulatifomu yensizakalo yokukala imishini noma ibhuloho lesikali (isikali samaloli kagesi noma isikali sikaloliwe) kusetshenziswa izinzwa ezimbalwa ochungechungeni, isofthiwe yesistimu yedatha ingasetshenziswa ukuqedela.“ukuzilinganisa”.

Lokhu kungenxa yesofthiwe yesistimu yezinzwa zedijithali enamashaneli amaningi, ayikho inkinga yokumelana okufanayo. Ikhasimende lifaka ikheli elinemininingwane, isisindo kanye nokuzwela kwenzwa ngayinye, futhi isikali singazenzakalela ngokugcwele.“amakhona amane”noma“umphetho”Ukulinganisela, asikho isidingo sokulungisa njalo uhlamvu ngokuphindaphindiwe. Ekulingiseni kwesistimu, ngemva kokuba izinzwa ezimbalwa zixhunywe ndawonye, ​​izici zenzwa ngayinye ngeke zisahlukaniswa kwezinye. Lapho ulinganisa, isisindo esijwayelekile kufanele sikhishwe kunzwa ngayinye futhi kusetshenziswe isihlukanisi sikagesi kutheminali. Yenza ukulungisa.

Ngoba kukhona ukuhlolwa kuka-t okubhangqiwe lapho kulungiswa, kuphindaphindwa izikhathi ezimbalwa. Kusofthiwe yesistimu yedatha, inzwa ngayinye ivunyelwe ukuthi ihlolwe iyodwa. Ngakho-ke, isikhathi sokulungisa izindleko eziphelele zesofthiwe yesistimu enenzwa yedijithali yi-1/4 kuphela yokulinganisa kwesistimu.

Kungenziwa kusetshenziswa isofthiwe yesistimu yedatha“ozixilongile”, okungukuthi, ukugeleza kohlelo lokuxilonga kuhlola ngokuqhubekayo ukuthi ingabe isignali yedatha yenzwa ngayinye inqanyuliwe, ukuthi okukhiphayo kweqiwe kakhulu, njll. Uma kunenkinga, umlayezo noma i-alamu iboniswa ngokuzenzakalelayo kudeshibhodi noma iphaneli yokulawula yephaneli. , futhi amakhasimende angasebenzisa okhiye kuphaneli yokulawula ukuze athole inzwa ngayinye, ahlonze imbangela yenkinga ngawodwana futhi enze ukuxazulula inkinga okuvamile. Lolu hlobo lokuxilongwa kokwahlulela kanye nomsebenzi ojwayelekile wokusula amaphutha ngokusobala kuyinzuzo eyinhloko kumakhasimende, futhi kunzima ukukhohlwa nokunciphisa izindleko ekulingiseni isofthiwe yesistimu yezinzwa ze-analog.

Embonini yokukala, ukuxazululwa kwe-SPWM ye-displacement coefficient ye-software yesistimu yenzwa yokulingisa amabhithi angu-16, futhi kukhona izibalo ezitholakalayo ezingu-50,000; kuyilapho ukulungiswa kwesikrini kwenzwa ngayinye kusofthiwe yesistimu yedatha kungu-20 Bit, kunezibalo ezitholakalayo ezingu-1,000,000. Ngakho-ke, isofthiwe yesistimu enezinzwa zedijithali ezi-4 ingakhiqiza ukulungiswa kwesikrini kwezibalo ezingu-4,000,000. Izinzuzo zalolu hlobo lwamaphikseli aphezulu zifaneleka ikakhulukazi izindawo lapho isisindo sefreyimu yesikali sikhulu kakhulu futhi isisindo senetha sento ekaliwe sincane.

Isibonelo: kumishini yokukala i-seasoning, ngezinye izikhathi uhlobo oluthile lwezinto zokusetshenziswa ku-recipe eyimfihlo kuphela landisa ingxenye encane, kodwa izidingo zokunemba zisaphakeme kakhulu. Lokhu futhi kunzima ukukufeza ekufanisweni kwesistimu yendabuko. ezintathu. Ukusetshenziswa komxube we-rotary nomthelela wamathemba emakethe Ngenxa yokuthi ukulinganisa nokuqinisekiswa kwe-rotary mixer e-China kuhlala kuyindlela evamile, ithemba lokufaka isicelo sokumaketha nokukhuthazwa kwe-multihead weigher lizoba banzi kakhulu. , Inqubo yokuxuba eqhubekayo yebitumen inoshintsho lokuketula, futhi ukulawula okunembile kokugeleza okuphelele kungaveza ingxube ekahle kakhulu.
