Umbhali: Smartweigh– Isisindo Sezinhloko Eziningi

1. Ukwakheka kanye nemingcele yobuchwepheshe yesilawuli sokukala sesisindo se-multihead weiger I-Multihead weiger iyisistimu yokulinganisa eguquguqukayo esetshenziswa kakhulu ku-inthanethi, equkethe kakhulu i-load belt conveyor, i-carrier, imishini yokuhlola, i-weighing control, isisindo esiphelele Setha imishini nezinye izingxenye, ngokuhlonza okuzenzakalelayo, ukuqinisekiswa kokulinganisa okuguquguqukayo nezinye izici. Ngesikhathi somsebenzi, ngaphandle kokulawula ngesandla, i-load belt conveyor izothumela ngokuzenzakalelayo izinto zokusetshenziswa ezizolinganiswa kumthwali, ngokusho kwezingxenye ezimbili zokuhlola ezibonakalayo ezinhlangothini zombili zepulatifomu yokulinganisa ukuze kuhlukaniswe indawo yezinto zokusetshenziswa ezizolinganiswa, futhi zisethwe kusengaphambili ngokusho kwemishini yokusetha. Ububanzi obuhle besisindo esiphelele bokwenza ukuhlolwa. Ukuze kugcinwe kangcono izinto zokusetshenziswa ezilinganiswa esikalini ngokuya ngesivinini somthwali, kunqunywe ukuthi iphaneli yokulawula isisindo kufanele isheshe, inembe futhi ithembeke.

Isilawuli sokukala sisetshenziselwa ukulawula isisindo se-tread multihead eqenjini lokucindezela kwe-tread ensimini yerabha evulcanized. Sakhiwe kakhulu uhlelo lokulawula oluzenzakalelayo olwakhiwe ngama-microcomputer angu-51 angama-single-chip, i-preamplifier, idivayisi yokusetha, isibani sokubonisa imiphumela yokuhlola, ikhawunta ye-elekthronikhi, i-copier, ugesi wokushintsha, nokunye okunjalo. Uhlaka lwayo oluyisisekelo luboniswe kuMfanekiso 1.

I-preamplifier yandisa ukuphuma kwesignali yedatha yezinga le-millivolt yi-sensor yokucindezela okusebenzayo, iyiguqule ibe yisignali ehlukile, bese iyithumela ohlelweni lokulawula oluzenzakalelayo lwe-CS-51 single-chip ukuze kucutshungulwe idatha. Ububanzi besisindo esibekiwe buyaqhathaniswa, futhi umphumela wokuqhathanisa usekelwe ekuvulekeni nasekuphumeni kwesibani sokubonisa ukuze kuboniswe ulwazi, ikhawunta ye-elekthronikhi ukuze kubalwe, bese uqala umshini wokukopisha ukuze kuqoshwe ulwazi lwedatha yokukhiqiza. Isilawuli sokukala sinezindlela ezimbili zokusebenza: ukusebenza kanye nokulinganisa. Uma indlela yokulinganisa ikhethiwe, izofaka idatha engaguquki futhi ibonise ulwazi ngokujwayelekile.

Ngalesi sikhathi, beka into ezolinganiswa epulatifomu yokukala, iphaneli yokulawula izobonisa isisindo esiphelele sento ezolinganiswa, futhi isikali singalinganiswa. Uma indlela yokusebenza ikhethiwe, isilawuli sokukala sizongena ekusebenzeni kokukala nokuhlola okuguquguqukayo. Ngalesi sikhathi, isilawuli sokukala sizohlola izimpawu zedatha ezibonakalayo zezingxenye ezizolinganiswa kuzo zombili izinhlangothi zepulatifomu yokukala, sihlonze izingxenye zokunyathela, futhi senze imisebenzi yokukala nokuhlola okuguquguqukayo.

Ezweni lakithi, izilawuli zokulinganisa ezisetshenziselwa izikali zamakhanda amaningi ziyimikhiqizo engeniswa kakhulu, futhi iningi lemikhiqizo ethuthukiswe futhi yaklanywa eShayina isuselwa ekubonisweni kwesisindo okujwayelekile. Isigaba sokuhlola sesisindo esiphelele sifakwa yikhibhodi. Uma konke kusebenza kahle, abasebenzi bangempela abasebenzayo abakwazi ukubona inani elihleliwe, isithombe asisihle, futhi ukulungiswa akulungile. Isilawuli sokulinganisa esakhiwe futhi saklanywa yithi silingisa amasampula aphesheya kwezilwandle, futhi izinkinobho ezine ze-DIP ezinezikhundla ezine zisethwa kuphaneli yokulawula yebhodi yokulawula ukuze kusethwe ububanzi bokuhlola isisindo esiphelele. Izinkinobho ezine ze-DIP zingahlukaniswa ngezigaba ezinhlanu zesisindo esiphelele ngokuya ngobuchwepheshe bokucubungula (bheka Umfanekiso 2).

Izinombolo ezimbili zokuqala zedatha enezinombolo ezine zimelela inani eliphelele, kanti izinombolo ezimbili zokugcina zimelela idesimali. Phakathi nenqubo yonke yokulinganisa nokuhlola okuguquguqukayo, inani elisethwe kusengaphambili lingalungiswa noma nini nanoma kuphi. Setha izibani zokubonisa ezihambisanayo kanye nama-counter esisindo ngasinye esiphelele kuphaneli yokulawula.

Abasebenzi bangempela abasebenzayo bangalungisa ngokushesha ingcindezi yokusebenza kwe-tread extrusion inlet ngokuya ngokuhlaziywa kwethrendi yesisindo esiphelele esiboniswe yiphutha eliphezulu kanye nephutha eliphansi ukulawula isisindo esiphelele se-tread. Ngaleyo ndlela, kubonakala kakhulu futhi kulula. Irejista ngayinye yamadijithi ayisithupha inolwazi lwedatha olufana nokulinganisa okuhle, iphutha eliphezulu, iphutha eliphansi, ukuphambuka okuphezulu, ukuphambuka okuphansi, ivolumu yokukhiqiza (kufaka phakathi okuhle, iphutha eliphezulu, kanye nephutha eliphansi).

Ifakwe umshini wokukopisha ukuze ukopishe idatha nolwazi olufana nomkhiqizo wokuzalwa, olulungele ukuphathwa kwe-workshop yokukhiqiza. Emikhiqizweni engafaneleki enokuphambuka okuphezulu nokuphambuka okuphansi, imishini yokuhlola izovulwa ngokuzenzakalelayo ukuze isuswe, futhi kuzokhala i-alamu ukukhumbuza abasebenzi abasebenzayo ukuthi banake. Isilawuli sokukala asigcini nje ngokuba nemisebenzi yokulinganisa umsindo oguquguqukayo nokusebenza kokuhlola, kodwa futhi sinomsebenzi wokulandelela okuzenzakalelayo kwe-zero-point, ukuhlubula, kanye nokususa i-zero-clear, njll. Siyimitha yethuluzi lokubonisa elisezingeni eliphezulu elinembile.

Amapharamitha ayo abalulekile okusebenza yile:. Isikrini sokubonisa: ishubhu yokubonisa yedijithali ye-LED enezinombolo ezine enezigaba eziyisikhombisa.

Okuqukethwe okungelula kakhulu, njengokukopisha, izindlela zokucubungula idatha, kanye nokuhlolwa kwesisindo kanye nokuhlonza, kunikezwa emsebenzini wokuphatha ingemuva; kuyilapho okuqukethwe okusebenziseka kakhulu ekuqoqweni, ekusebenzeni kwesikhathi, njll., kunikezwa kumuntu okwamukelayo. Ukuthuthukiswa kwesofthiwe kusebenzisa isakhiwo sokuklama se-modular, esihlukaniswe ngamamojula amaningana ohlelo ngokwemisebenzi yansuku zonke, okuwusizo ekulungiseni, ekukhuliseni nasekutshalweni kabusha.

Umdwebo wohlaka olulula wohlelo lomthombo uboniswe kuMfanekiso 3. Ukuze kwenziwe ukulinganisa idatha engaguquki kanye nokuhlola nokulinganisa okuguquguqukayo, ukugeleza kohlelo ikakhulukazi kwenza ukuhlaziywa kokusebenza kanye nomklamo wokulwa nokuphazamiseka. Ngayinye ichazwe ngezansi.

1. Ukuhlaziywa komsebenzi Ukuhlaziywa komsebenzi wesofthiwe yeselula ngokuyinhloko kuhloswe ukuklama amamojula ahlukahlukene ohlelo, futhi ngokusho kwale module yohlelo, kufeza imisebenzi eyahlukahlukene ebalulekile yansuku zonke. Kulolu hlelo, imisebenzi ebalulekile eyenziwa yisofthiwe yeselula ingaba:. Ukulandelela okuzenzakalelayo kwe-zero-point;. Ukuhlubula;.. Ukulinganiswa kwe-zero-point;. Ukuqoqwa kwedatha; Ukusebenza kwesikhathi;. Funda ukhiye kanye nokusetha;. Ukuguqulwa kokusebenza/ukuhlola;. Kopisha;. Vula inani lolwazi olubonisiwe ngaphansi kwendlela yokusebenza;. Ngaphansi kokuphathwa kohlelo lokuqapha uhlelo, le module yohlelo yenza idatha engaguquki enesisindo noma ukuhlolwa okunamandla kanye nokulinganisa ngokwecebo lokuqalisa elinqunyiwe.

2. Uhlelo lokuklama olulwa nokuphazamiseka Ngenxa yokuthi isisindo se-multihead sisebenza endaweni yemvelo yokukhiqiza kwezimboni, kunezithonya ezahlukahlukene khona manjalo, ezibeka engcupheni umsebenzi ojwayelekile wesikali. Ngakho-ke, ngaphezu kwezindlela zokulwa nokuphazamiseka kokumiswa kwehadiwe, izindlela zokulwa nokuphazamiseka kwesofthiwe yeselula njengokuzivikela kwesibili nazo zibaluleke kakhulu futhi azinakwa. Isofthiwe yohlelo lomsindo akufanele nje yenze ukuhlaziywa okusebenzayo, kodwa futhi yenze uhlelo lokuklama olulwa nokuphazamiseka ukuze kuthuthukiswe ukuthembeka kwesofthiwe yohlelo.

Isofthiwe yesistimu ikhetha izindlela ezimbili ezilandelayo zokulwa nokuphazamiseka kwesofthiwe yeselula: (1) Ukuphazamiseka kwe-electromagnetic okulwa nokuphazamiseka kwesiteshi sokuphepha se-analog signal I/O kufana kakhulu ne-burr, futhi isikhathi somphumela sifushane. Ngokusho kwalesi sici, lapho kuqoqwa isignali yedatha yesisindo esiphelele, ingaqoqwa ngokuqhubekayo izikhathi eziningana, kuze kube yilapho imiphumela yamaqoqo amabili aqhubekayo ifana ngokuphelele, isignali yedatha inengqondo. Uma isignali yedatha ingahambisani ngemva kwamaqoqo amaningana, ukuqoqwa kwesignali yedatha yamanje kuzolahlwa.

Umkhawulo wemvamisa ephezulu yeqoqo ngalinye kanye nemvamisa efanayo eqhubekayo kungalungiswa ngokuya ngezidingo ezithile. Inani eliphezulu eliqoqwe kulolu hlelo lokugeleza liyizikhathi ezine, kanti izikhathi ezimbili ezilandelanayo nazo ziyiqoqo elifanele. Kusiteshi sokuphepha kokukhipha, noma ngabe i-MCU yakhelwe ukuthola ulwazi olufanele lwedatha yokukhipha, idivayisi yokukhipha ingathola ulwazi lwedatha olungalungile ngenxa yethonya langaphandle.

Kusofthiwe yeselula, indlela enengqondo yokuvimbela ukuphazamiseka ukukhipha ulwazi olufanayo lwedatha ngokuphindaphindiwe. Isikhathi somjikelezo wokuphindaphinda sifushane ngangokunokwenzeka, ukuze ngemva kokuthola umbiko wephutha othintekile, idivayisi engaphandle ingakwazi ukuphendula ngendlela efanele ngesikhathi, futhi okuqukethwe kolwazi lokukhipha okufanele kubuye futhi. Ngaleyo ndlela, ukuma okungalungile kuyagwenywa ngokushesha.

Kulolu hlelo, umphumela ubekwa ekuphazamisekeni kokwenziwa kwesikhathi, okungagwema ngokufanele ukusebenza kwephutha lomphumela. (2) Ukuhlunga kwedijithali kuhloselwe isignali yedatha yesisindo esiqoqiwe, evame ukuba nethonya elingahleliwe, ngakho-ke kuyadingeka ukuthola ulwazi lwedatha olusondelene nenani langempela lephuzu kusuka emikhiqizweni yochungechunge lolwazi lwedatha, futhi uthole umphumela onezinga eliphezulu lobuqiniso. Kusofthiwe yeselula, indlela evamile ukuhlunga kwedijithali.

Lokhu kugeleza kohlelo kuhlukaniswe ngesisindo sedatha esingaguquki kanye nesisindo sokuhlola esiguquguqukayo. Ngenxa yezindlela ezahlukene zokulinganisa, izindlela zokuhlunga zedijithali ezikhethiwe nazo zihlukile. Izindlela ezahlukene zokuhlunga zedijithali ezisetshenziswa izindlela ezimbili zokulinganisa ziboniswe ngezansi ngokulandelana.

¹Ukulinganisa idatha engaguquki: Ukucatshangelwa okuyinhloko kokulinganisa idatha engaguquki ukuthembeka nokunemba kwesofthiwe yesistimu. Kubalulekile ukucabangela ukuzinza okulinganiselwe kolwazi olubonisiwe ngaphansi kwezimo ezizinzile kanye nokuphendula okusheshayo ngesikhathi sokulayisha. Ngakho-ke, ukuhlonza ukuthembeka kolwazi oluqoqiwe lwedatha kufanele kwenziwe kuqala, bese kwenziwa isisombululo sokuhlunga sedijithali.

Enkambisweni yenqubo yokuhlunga yedijithali, kukhethwa indlela yokuhlunga yesilinganiso esinyakazayo ukuze kuthuthukiswe umphumela wokuhlunga wangempela. Indlela ethile yile: isikhathi ngasinye lapho kuthathwa isampula, olunye lolwazi lwedatha lokuqala luyasuswa, bese kuba nenani lesampula lalesi sikhathi kanye nenani lesampula lezikhathi eziningi zangaphambilini lilinganiswa ndawonye, ​​​​futhi inani lesampula elifanele elitholwe ngumuntu ngamunye lingalethwa ukuze lisetshenziswe. Ngakho-ke, lokhu kuthuthukisa ukusetshenziswa kwesofthiwe yesistimu.

Ukukhethwa kwemvamisa yokuthatha amasampula u-N kuyingozi enkulu emphumeleni wangempela wokuhlunga. Uma i-N inkulu, umphumela wangempela ungcono, kodwa kuzobeka engozini impendulo eguquguqukayo yesofthiwe yesistimu. Kulesi silawuli sokulinganisa, ukuze kuthuthukiswe ukuthembeka kwesofthiwe yesistimu kanye nekhono lokuphendula ngokushesha, u-N u-32 uma uzinzile, kanye no-8 uma ungazinzile.

Ngenxa yokukhetha indlela yokuhlunga efanelekile, ukuthembeka nokunemba kwesofthiwe yesistimu kanye nesikhathi sayo sokuphendula ukulayisha kuye kwathuthukiswa kakhulu.ºUkuhlolwa nokulinganisa okunamandla: Ekuhlolweni nasekulinganisweni okunamandla, ukunyathela kusekelwe ngokushesha epulatifomu yokukala. Ukunyathela kungaphakathi kwemizuzwana eyi-1.5, ngakho-ke ukusampula kumele kwenziwe ngaphakathi kwesekhondi eli-1.

Ngaleyo ndlela, imvamisa yokuthatha amasampula inqunyelwe. Ngaphezu kwalokho, ngoba ukunyathela kuzobangela ukudlidliza okuthile uma kulungiswa ngokushesha endaweni yokulinganisa, kuzothinta inani lokuthatha amasampula. Ngakho-ke, kubaluleke kakhulu ukucabangela ukuthi yiluphi ulwazi lwedatha olusebenzayo nokuthi hlobo luni lobuchwepheshe bokuhlunga bedijithali olukhethiwe ukuze kuncishiswe umonakalo wokulingana okunzima kokuphazamiseka kwe-electromagnetic.

Ngokusho kokubonwa okuqondile, i-waveform yesignali yedatha yesisindo se-multihead iboniswe ku-Figure 5. Kulesi sithombe, kusukela ekufikeni kwe-tread kuya epulatifomu yokulinganisa kuze kube yilapho isuka khona ihlukaniswe ngezixhumanisi ezintathu: isigaba sokuqala yisikhathi u-t, ingxenye, okuyinqubo yonke kusukela ekufikeni kwe-tread kuya epulatifomu yokulinganisa kuze kube yilapho isiphelele epulatifomu yokulinganisa. Isignali yedatha yesisindo esiphelele isifikile. Isigaba sesibili yisigaba sesishiyagalolunye, i-tread isepulatifomu yokulinganisa ngokuphelele, futhi lesi sikhathi yisigaba sokulinganisa; isigaba sesithathu yisikhathi u-t. Isigaba yinqubo yonke lapho i-tread ishiya khona ipulatifomu yokulinganisa, futhi isignali yedatha yesisindo esiphelele yehla kancane kancane ibe yi-zero phakathi nalesi sikhathi.

Ekuqaleni nasekupheleni kwezingxenye eziyisishiyagalolunye ezinesisindo, isignali yedatha yokukala ibhekana nemiphumela enzima kakhulu. Engxenyeni yezintaba, okungukuthi, lapho i-tread iphakathi kwepulatifomu yokukala, isignali yedatha yokukala izinzile. Ngakho-ke, kungcono kakhulu ukukhetha ulwazi lwedatha lobubanzi besikhathi se-Δt.

Sebenzisa isikali esibekiwe ukuze uhambe uye ekugcineni kweswishi ye-photoelectric ukuze uqale isilawuli sokukala ukuze uthole ulwazi lwedatha yokusampula olushintshashintshayo, bese usampula ngaphakathi kwesikhathi sentaba. Imvamisa yokusampula u-N ihlobene nesilinganiso sokusampula. Uma isivinini sokusampula sishesha, imvamisa eqoqiwe u-N iphakeme. Ukufakwa kweswishi ye-photoelectric kumele kuqinisekiswe ukuthi idatha ebonakalayo eqoqiwe iwulwazi lwedatha lapho into ezolinganiswa itholakala edolobheni laseWeitaishan.

Ulwazi lwedatha ye-N oluqoqwe, zonke zinezingxenye zethonya ezahlukene, ngakho-ke kuyadingeka ukukhetha indlela yokuhlunga efanelekile ukuze uthole inani langempela lesisindo se-tread net. Le nqubo ikhetha ubuchwepheshe bokuhlunga obuhlanganisiwe, okungukuthi, ukusetshenziswa kwezindlela ezimbili noma ngaphezulu zokuhlunga zedijithali kuyahlanganiswa futhi kuyasetshenziswa, okunganele ukuhambisana, ukuze kuthuthukiswe umphumela wangempela wokuhlunga, ukuze kufezwe umphumela wangempela ongenakufezwa ngendlela eyodwa yokuhlunga. Lapha, kukhethwa indlela yokuhlunga ehlanganisa indlela yokuhlunga yenani eliphezulu kanye nendlela yokuhlunga ephakathi kwezibalo.

Ukuhlunga kwe-De-maxima kuqala kususa inani elibalulekile lethonya le-single-pulse, futhi akubhaliseli ukubalwa kwenani elimaphakathi, ukuze inani lokukhipha lokuhlunga elimaphakathi lisondele enanini langempela. Isimiso esiyisisekelo se-algorithm yokwenza ngcono simi kanje: qhubeka nokusampula izikhathi ze-N, uqoqe futhi ucele isihe, bese uthola amanani aphezulu naphansi kuwo, bese ususa amanani aphezulu naphansi ekuqongeleleni nasekuqondeni, bese ubala ngokwenani elilodwa noma amabili okulinganisa i-N. isilinganiso, okungukuthi, ukuthola inani elifanele lokulinganisa. Ishadi lokugeleza kwenqubo yokuhlunga inhlanganisela liboniswe kumdwebo we-waveform wesignali yedatha yokulinganisa ku-Fig. 5. Kusukela ekufikeni kwe-tread kuya epulatifomu yokulinganisa kuze kube yilapho isuka, ihlukaniswe ngezixhumanisi ezintathu: isigaba sokuqala yisikhathi i-t, ingxenye, okuyisikhathi lapho i-tread ifika esikalini. Yonke inqubo kusukela epulatifomu kuze kube yilapho isiphelele epulatifomu yesikali, isignali yedatha yesisindo esiphelele ikhuphuka kancane phakathi nalesi sikhathi; isigaba sesibili yisikhathi sesishiyagalolunye, i-tread isepulatifomu yesikali ngokuphelele, lesi sikhathi isigaba sokulinganisa; isigaba sesithathu Leso yisikhathi i-t.

Ingxenye iyinqubo yonke lapho i-tread ishiya khona ipulatifomu yokulinganisa, futhi isignali yedatha yesisindo esiphelele yehla kancane kancane ibe yi-zero phakathi nalesi sikhathi. Ekuqaleni nasekupheleni kwezingxenye eziyisishiyagalolunye zokulinganisa, isignali yedatha yokulinganisa ibhekana nemiphumela enzima kakhulu. Engxenyeni yezintaba, okungukuthi, lapho i-tread iphakathi kwepulatifomu yokulinganisa, isignali yedatha yokulinganisa izinzile.

Ngakho-ke, kungcono kakhulu ukukhetha ulwazi lwedatha lwesikhathi se-Δt. Sebenzisa isikali esibekiwe ukuze uhambe uye ekugcineni kweswishi ye-photoelectric ukuze uqale isilawuli sokukala ukuze uthole ulwazi lwedatha yesampula eguquguqukayo, bese usampula ngaphakathi kwesikhathi sentaba. Imvamisa yesampula u-N ihlobene nesilinganiso sesampula. Uma isivinini sesampula sishesha, imvamisa eqoqwe u-N iphakeme.

Ukufakwa kweswishi ye-photoelectric kumele kuqinisekiswe ukuthi isilinganiso sezibalo samanani aqoqwe kufomula kanye no-N siyisilinganiso sezibalo samanani amasampula ama-2; u-w uyinani lesampula le-i-th; u-N uyisilinganiso sesampula. Ukuze kube lula ukubala, imvamisa yesampula ngokuvamile ikhethwa njengo-6, 10, 18 njengo-2 emandleni enani eliphelele lika-2 kanye no-2, okulula ukusebenzisa i-shift esikhundleni sokuhlukanisa. Kulolu hlelo lokugeleza, ikhambi likhethwa ngenkathi kwenziwa isampula, ngakho-ke asikho isidingo sokuthuthukisa indawo yokugcina ulwazi lwedatha ku-ruler AM.

Ngemva kokuhlunga kwedijithali, kutholakala inani le-W, bese kwenziwa izindlela zokucubungula idatha njengokuhlubula kanye nokuguqulwa kwamaphutha ajwayelekile ukuze kutholakale inani lesisindo se-tread solwazi lokubonisa, ukuhlonza kanye nokukopisha. Ngemva kokuthi inkinobho yesibili ye-photoelectric ithole ukuthi i-tread isiphumile ngokuphelele epulatifomu yokulinganisa, qala i-assembler yokulandelela i-zero-point, khetha isampula enkulu yesampula bese uhudula ubuchwepheshe bokuhlunga obujwayelekile, bese ususa ngokuzenzakalelayo i-tare, ukuze ulungiselele ukufika kwe-tread elandelayo.
