Izinzuzo kanye nesiqondiso sentuthuko yesisindo se-digital multihead

Umbhali: Smartweigh– Isisindo Sezinhloko Eziningi

Ekukhiqizweni kwezimboni kobuchwepheshe bokuzenzakalela kanye nemishini yokulinganisa kagesi yomphakathi, kusetshenziswa iningi lezikali ze-multihead zesignali ye-pulse eziyisisekelo, kanti izikali ze-analog multihead zedijithali ziphinde zisetshenziswe kulesi sigaba. Ngenxa yesiginali ye-pulse ebangelwa yisimiso esiyisisekelo sokuguqulwa kwamandla okucindezela kwe-resistor, kumele kube yi-pulse signal eguqulwa ibe yi-analog working voltage noma i-analog current eyenziwe ngokulinganisa ngokusho kwe-smart transmitter. Kuye kwaqoqwa ulwazi oluningi lomsebenzi kubuchwepheshe bokukhiqiza nokucubungula, isinxephezelo sesekethe yamandla nokulungiswa, ukuguqulwa kwe-pulse nezinye izici, ngakho-ke uhlelo lokusebenza luvame kakhulu. Kodwa-ke, isignali yedatha yokukhipha incane, ibanga lokudlulisa lifushane, futhi ukusebenza kokulwa nokuphazamiseka kubi. Izinto ezintsha zesinxephezelo zihambisana ne-t-test. Isinxephezelo sesekethe yamandla nobuchwepheshe bokucubungula ukulungiswa buyinkimbinkimbi, okungagcini nje ngokuthatha isikhathi nomsebenzi, kodwa futhi kunokunemba okuphansi kwesinxephezelo; ithuluzi lokulawula ulwazi lokubonisa isisindo liyinkimbinkimbi, ukushiyeka kokuzalwa njengokufakwa okungafanele nokulungiswa kunqume ukuthambekela kokuthuthukiswa kwezikali ze-digital ne-analog multihead eziya ekubonisweni kwedijithali. Imojula yokuguqulwa kwedijithali kuphela ngaphandle kwesekethe yebhuloho le-strain force eyi-parasitic, futhi isignali ye-pulse ishintshwa ibe isignali ye-analog.

Ngakho-ke, sekuvele indlela yokuguqula idijithali. Enye iwukuguqula isignali yedatha yokukhipha ye-digital analog multihead weigher ibe yi-analog signal output ngokuya nge-data intelligent transmitter efakwe kuyo, ngokuvamile ebizwa ngokuthi i-intelligent multihead weiger. Okungukuthi: i-digital analog multihead weiger + i-data intelligent transmitter = i-digital display multihead weiger. I-digital display sensor isebenzisa i-integrated A/D conversion power supply circuit, i-intelligent data signal transmission kanye nobuchwepheshe bokuhlunga idijithali. Ibanga lokudlulisa isignali yedatha ye-sensor likude kakhulu, futhi i-anti-interference inamandla. I-shielding case, lezi zici ezimbili zodwa zinquma izinzuzo ze-anti-interference yayo, futhi zithuthukise ukuthembeka kwe-inductor ezingeni elikhulu kakhulu.

Isikali se-digital display multihead siguqula isignali ye-sensor pulse yendabuko ibe isignali ye-analog ye-RS485 enembile kakhulu, engasusa isidingo sokulinganiswa, futhi ingasetshenziswa ezinhlelweni zokulawula okuzenzakalelayo zokukhiqiza kwezimboni. Okuqukethwe kolwazi lwamandla alayishiwe kwe-applicator kuguqulwa kube isignali ye-analog. Inzwa yokucindezela kokudonsa isisindo ibizwa ngokuthi i-cardiovascular yemishini yokulinganisa, futhi izici zayo zinquma ukunemba nokuthembeka kwemishini yokulinganisa ezingeni elikhulu kakhulu. Lapho uklama imishini yokulinganisa, kuvame ukuba nzima ukusebenzisa izinzwa.

Indlela yokusebenzisa isisindo esinezici ezinhle I-multihead weiger empeleni iyithuluzi eliguqula isignali yedatha yekhwalithi ibe yi-electronic signal output engalinganiswa ngokunembile. Uma usebenzisa i-sensor, kufanele uqale ucabangele indawo ethile yehhovisi lapho i-sensor itholakala khona. Lokhu kubaluleke kakhulu ekusetshenzisweni okufanele kwe-sensor. Kuhlobene nokuthi i-sensor ingasebenza kahle yini, ezinye izici zokuphepha kanye nezikhathi zesevisi, kanye nokutholakala kwazo zonke izingxenye ze-elekthronikhi. Ngakho-ke ungayikhetha kanjani i-pressure sensor enamandla yokukala nokudonsa? Ngizokunikeza isingeniso esinemininingwane ngezansi.

Izinzwa zokucindezela zokulinganisa nokudonsa zisetshenziswa kabanzi kuma-gauge ahlukahlukene okumelana nohlobo lwe-foil anenani lokumelana elingu-350Ω, ukuze kwenziwe imishini ehlukahlukene yokulinganisa, enokunemba okuphezulu okuphelele, ukuthembeka okuhle kanye nolwazi lokubonisa ezinhlelweni ezithile. Ukulula nezinye izici. Indawo yokusebenza yenzwa yokucindezela yokudonsa isisindo: inzwa yokucindezela yokudonsa isisindo empeleni iyidivayisi yokukhipha eguqula isignali yedatha yekhwalithi ibe yidivayisi yokukhipha isignali kagesi engalinganiswa ngokunembile. Uma usebenzisa inzwa, kufanele uqale ucabangele indawo ethile yehhovisi lapho inzwa ikhona khona. Lokhu kubaluleke kakhulu ekusetshenzisweni okufanele kwenzwa. Kuhlobene nokuthi inzwa ingasebenza ngokujwayelekile yini kanye nezinye izikhathi zokuphepha nokusebenzisa, ngisho nokuthembeka kwazo zonke izinto zikagesi.

Ngaphansi kwezimo ezivamile, indawo yemvelo eshisa kakhulu ibangela izinkinga ezifana nokuncibilika kwezinto zokusetshenziswa zokumboza, ukushisela amabala, kanye nokuguqulwa kwesakhiwo sokucindezeleka kokushisa kwe-polyurethane elastomer kuya ku-sensor; intuthu, uthuli, umswakama kanye nokubanda kubangela ukwehluleka kwe-short-circuit ye-sensor; endaweni enokugqwala okuphezulu Kungabangela umonakalo kwi-polyurethane elastomer ye-sensor noma kubangele isimo sephutha le-short circuit; insimu yamagnetic izothinta ukuphuma kwe-sensor. Ngaphansi kwezici zemvelo ezihlobene, kufanele ukhethe amandla afanayo alinganisa isisindo sama-multihead ngaphambi kokuthi ucabangele imithethonqubo yokulinganisa edingekayo.
