Umbhali: Smartweigh–I-Multihead Weighter

Ukuthuthukiswa kobuchwepheshe kokuqinisekiswa kwe-rotary metrological kanye nesimiso saso esiyisisekelo sesisindo esingenasisindo 1. Isimo samanje sendlela yokuqinisekisa ukulinganisa ye-Rotary mixer 1.1 Indlela yokuqinisekisa ukulinganisa okujikelezayo yokusetshenziswa kwendabuko inezindlela eziningi ekuqinisekisweni kokulinganisa kwezinto ezingavuthiwe ze-fibrous ezifana nokuhlobisa. izinto zokwakha, okusanhlamvu, uwoyela, ukudla, izimayini, njll., noma uma ukhohlisa izinongo ku-inthanethi . Ezakudala kakhulu yilezi: izikali zamabhande e-electronic, ama-flushing plate flowmeters, izikali zenuzi, nezikali zokuphakela amadiski. Le ndlela yokuqinisekisa ukulinganisa inezici zayo, kodwa imikhawulo mikhulu kakhulu.

Ubuchwepheshe bokucubungula isikali sebhande le-elekthronikhi kwethulwa ngokuningiliziwe. Izinyathelo: Isikali sebhande le-elekthronikhi sihlanganisa isignali yedatha yomthwalo etholwe endaweni ephelele (isigaba sesisindo) sebhizinisi kanye nesignali yedatha yezinga loshintsho (isilinganiso sesivinini sebhande lokudlulisela) ukuze kutholwe inani lokugeleza okuphelele. Okuqondiwe okusebenzisekayo. Qaphela: Inani lezinto ezizokhishwa liyashintshwa ngokuya ngesilinganiso sejubane lebhande ledrayivu yokudonsa nokudonsa. Ngemva kokuba impahla eluhlaza ibunjwe futhi yenziwe ibe yinhle ngokusebenzisa imbobo yokudla ye-chute yokudla, ukuqina kwayo kuzinzile futhi kuyalingana. Kungakhathaliseki ukuthi isilinganiso sejubane lesithuthi sebhande, umthwalo ebhandeni lokushayela uhlala njalo. Uma kuqhathaniswa nezinye izindlela zokuphakela, le ndlela inomphumela omuhle wangempela wokuqinisekiswa kwe-metrological kanye nomugqa.

1.2 Ukusetshenziswa kwendlela yokuqinisekisa i-rotary metering emishinini yokuhlanganisa eqhubekayo Imishini yamanje yokuhlanganisa ejikelezayo ihlanganisa: imishini yokuhlanganisa usimende ezinzile nemishini yokusebenza, imishini yokuhlanganisa ukhonkolo ejikelezayo, kanye nemishini yokuhlanganisa i-bitumen rotary. Ngokuphathelene nokunemba kokuqinisekiswa kwe-metrological, kulesi sigaba, lolu hlobo lwesisetshenziswa alukwazi ukwenziwa olujwayelekile ngezikhathi ezithile. Ngakho-ke, indlela yokuxuba i-rotary ayithandwa ngabathengi abaningi, okungenye yezici.

Ukuboniswa kwesayensi kungabonisa ukuthi ubuchwepheshe bokuxuba nokucubungula okunqunywe yilezi zindlela ezimbili zokuqinisekisa ukulinganisa zonke ziyizindawo ezifanele, futhi ukusetshenziswa kokuxuba okujikelezayo akufanele kube sengozini ngenxa yemikhawulo yamanje 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 zingasetshenziswa e-Europe ngokunemba okuphezulu. Isibonelo, isikali sokuhlanganisa ibhande lokudlulisa se-Zhongshan Smart weigh sinokunemba okuguquguqukayo kwesinongo okungu-2%.

Kodwa ezweni lami, akukuhle, ngoba kuncike ekuvinjweni kokukhiqizwa kwezimboni eziyisisekelo ezifana nokukhiqizwa kwemishini nemishini kanye nezinto zokwakha ezweni lami. Kulesi sigaba, ukunemba kokuqinisekiswa kokulinganisa kwezikali zebhande le-elekthronikhi ezisetshenziswa emkhakheni womgwaqo e-China ngokuvamile cishe ku-5%, okungehlukile ekuqinisekisweni kokulinganisa umthamo, futhi ukwethembeka kwesikhathi eside akunamandla. ezimbili. Ukuguqulwa Kwesisindo Okuqhubekayo——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 entsha yokulinganisa, izinto ezingavuthiwe ziya ngokuya zisetshenziswa kancane kancane. 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 ngokusebenzisa izixazululo zobuchwepheshe ezihlukahlukene ze-hardware nesofthiwe, kungasetshenziswa njengenye ingxenye yokulungiswa.“ukugeleza okuphelele okuqondile”. Ukutholwa kwalokhu kugeleza kwedatha kubaluleke kakhulu, futhi kuyisisekelo sokulinganisa okunembile nokuqinisekiswa kwesikali esingenasisindo.

Indlela yendabuko 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 kokuhlosiwe, kanye nemiphumela. isignali yedatha yokulungisa ukusebenzisa isiqalisi esithambile nezinye iziphakeli ezidlidlizayo. Iphaneli yokulawula. 2.2 Ukusetshenziswa kwangempela kwesikali sokukala isignali ehlukile (i-multihead weigher): Kusukela kumgomo wokusebenza, kungabonakala ukuthi ngeke kuthinteke izinguquko zemishini yomshini womzimba wesikali kanye nesakhiwo sokuphakela. Ikala kuphela iphutha lesisindo senetha (isisindo somehluko), esihlukile kwesendabuko Uma kuqhathaniswa nezindlela zokuqinisekisa ze-metrological ashukumisayo, izici zayo zisobala. Uma okuqondiwe kokulawula kuwukugeleza okuphelele (t/h, kg/min), nezinto zokusetshenziswa zinokuthuthwa okuhle, futhi izinga lokunemba lokuqinisekiswa kwe-metrological liphezulu, indlela yesimo esingenasisindo sokuqinisekiswa kwe-metrological ingasetshenziswa njengohlelo olungcono kakhulu.

2.2.2 Inqubo yokukhiqiza yesisindo esingenasisindo: inqubo yokukhiqiza ye-multihead weigher 2.2.3 Izindaba ezidinga ukunakwa ohlelweni lokuklama lwesisindo esingenasisindo, izici ezithinta ukunemba: i-multihead weigher inezici zesikali sedatha e-static kanye nesilinganiso esiguqukayo. Lapho kwakhiwa isofthiwe yesistimu, kubalulwe ukuthi: 1. Ibanga elifanele lezinga lezokuthutha, ngokuvamile endaweni ethile yomsebenzi, u-60% kuya ku-70% womthamo wokuthutha olinganiselwe yiwona ongcono kakhulu. Uma kusetshenziswa ukuguqulwa kwesivinini sokuxhumana nokushintshanisa, kungcono ukuphendula imvamisa yokucindezeleka engu-35-40Hz. Lokhu kuqinisekisa uhla olubanzi lokulungisa.

Yingoba futhi uma izinga lokuhamba liphansi kakhulu, ukuzinza kwesofthiwe yesistimu kubi. 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 isistimu yomshini kufanele luqinisekise ukuthi izinto zokusetshenziswa zihamba kahle, futhi ziqinisekise ukuthi isikhathi sangaphambi kokusabalalisa sifushane, futhi ukuphakelwa akufanele kuvame kakhulu. Ngokuvamile, kuthatha imizuzu engu-5-10 ukugcwalisa impahla.

Futhi ukukhuphukela ku-0.1%~0.2%, noma ngisho nangaphezu kwesikali sedatha esimile, ukhiye wale nqubo entsha 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 ezindaweni okufanele zibe ezihlakaniphile, idatha ngesikhathi esisodwa noma engaqondile yenzwa ibalulekile. Ngalesi sikhathi, ukungaqiniseki kokulinganisa okunembile kanye nezinga lokutholwa kuvamise ukuba yipheya lomehluko, futhi kunzima ukulinganisa kokubili, futhi kuyadingeka ukunquma isimo esithile. Yenza ukuvumelana. Embonini yokukala, izinzwa eziningi ze-analog zedijithali zendabuko zikhiqizwa futhi zisetshenziswe ezweni lami, 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 impahla noma ibhuloho lesikali (isikali samaloli ka-elekthronikhi noma isikali sikaloliwe) kusetshenziswa izinzwa zokushisa eziningana ochungechungeni, uhlelo lokusebenza lwedatha lungasetshenziswa ukuqedela“ukuzilinganisa”.

Lokhu kungenxa yesofthiwe yesistimu yezinzwa zedijithali enamashaneli amaningi, ayikho inkinga yokumelana okufanayo. Ikhasimende lingafaka ikheli elinemininingwane, isisindo kanye nokuzwela kwesilawuli ngasinye, bese likwazi ukwenza ukulungisa isikali lilodwa.“amakhona amane”noma“umphetho”Ukulinganisela, asikho isidingo sokulungisa njalo uhlamvu ngokuphindaphindiwe. Kukulingisa kwesistimu, ngemva kokuba izinzwa ezimbalwa zixhunywe ndawonye, ​​izici zesilawuli ngasinye ngeke zihlukaniseke kwezinye. Lapho ulinganisa, isisindo esijwayelekile kufanele sikhishwe kunzwa ngayinye futhi kusetshenziswe amandla kagesi aphezulu kumatheminali. I-pressure regulator iyalungiswa.

Ngoba kukhona ukuhlolwa kuka-t okubhangqiwe lapho kulungiswa, kuphindaphindwa izikhathi ezimbalwa. Kusistimu yedatha, inzwa ngayinye ivunyelwe ukuthi ihlolwe iyodwa njengeyodwa. Ngakho-ke, isikhathi sokulungisa izindleko eziphelele zesofthiwe ngesistimu yezinzwa zedijithali yi-1/4 kuphela yokulinganisa kwesistimu.

Ukusebenzisa isofthiwe yesistimu yedatha nakho kungenziwa“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 ngawodwana imbangela yenkinga futhi enze ukuxazulula inkinga okuvamile. Lolu hlobo lokuxilongwa kokwahlulela kanye nekhono lokusula inkinga ngokusobala luyinzuzo eyinhloko kukhasimende, kodwa kunzima ukukhohlwa futhi ukwenze ngezindleko eziphansi ekufanisweni kwesofthiwe 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; futhi isinqumo sesikrini senzwa ngayinye ohlelweni lwedatha singamabhithi angu-20. , kunezibalo ezitholakalayo eziyi-1,000,000. Ngakho-ke, isofthiwe yesistimu enezinzwa zedijithali ezi-4 ingakhiqiza ukulungiswa kwesikrini kwezibalo ezingu-4,000,000. Izinzuzo zamaphikseli aphezulu anjalo afaneleka ngokukhethekile ezindaweni lapho uhlaka lwesisindo lunzima kakhulu futhi isisindo senetha sento yokukala sincane.

Isibonelo: kumishini yokukala yesinongo, ngezinye izikhathi uhlobo oluthile lwempahla eluhlaza lubalela kuphela ingxenye encane kuresiphi eyimfihlo, kodwa izidingo zokunemba zisaphakeme kakhulu.
