Amaphutha avamile kanye nezixazululo ze-electronic weighbridge multihead weigher

Umbhali: Smartweigh– Isisindo Sezinhloko Eziningi

Isihluthulelo sokugcinwa kwe-multihead weigher ukugcina ipulatifomu yesikali kanye nendawo lapho inzwa ibekwe khona, ngoba uma kukhona amanzi kule ndawo, kuzobeka engozini ukusetshenziswa okuvamile kwenzwa. Ngakho-ke, kubalulekile ukusetha ishedi kanye negumbi lokukala nelokulinganisa, ukuze inzwa ikwazi ukugcinwa kahle. Ngaphezu kwalokho, indawo yokuhlangana phakathi kwepulatifomu yokukala kanye nomthambeka oholayo kumele futhi ibe nendawo enhle yokuvula, ngaphandle kwalokho kulula kakhulu ukukhiqiza ukungqubuzana nokungqubuzana, futhi ukulingana kuzoholela ekulimaleni okuthile ngokungenakugwenywa.

Ngaphezu kwalokho, kuyadingeka futhi ukunakekela njalo ukuthi ngabe kukhona yini izinto ezingcolile ezinamathele phansi kwepulatifomu yesikali seloli kagesi. Uma kukhona izinto ezingcolile ezinamathele, kuzophinde kubeke engcupheni ukudluliswa kwesignali yedatha yenzwa, ngakho-ke kumele isuswe ngokushesha. Uma ukulungiswa okungenhla kungenziwa, kuzobangela ukwehluleka okuvamile kwenzwa, futhi ukulungiswa kweseli lomthwalo kuyisiphazamiso. Ngoba inzwa ihilela amazinga amaningana, uma ukulungiswa kungalungile, kufanele uyishintshe ngentsha. Izinzwa, lokhu kuzobiza imali eningi. Isisindo esilandelayo se-Zhongshan Smart sizokwethula amaphutha avamile kanye nezixazululo zesisindo se-electronic floor scale multihead kuwo wonke umuntu.

Amaphutha avamile kanye nezixazululo zethebula lokulinganisa amakhanda amaningi ezikalini zephansi ze-elekthronikhi: (1) Ukuhlaziywa kwamaphutha avamile angenakukwazi ukubuyela endaweni engu-zero ngemva kokuba into yokuphakamisa isusiwe ukuze kuhlolwe ukuthi inani lesignali yedatha yokukhipha yeseli yomthwalo lingaphakathi kwencazelo (inani le-A/D liba likhulu) ububanzi bekhodi/ikhodi yesicelo/ububanzi bekhodi yesisekelo), uma inani lesignali yedatha lingekho ngaphakathi kwencazelo, lungisa ukumelana okuguquguqukayo kwenzwa ukuze ulungise inani lesignali yedatha ngaphakathi kwencazelo. Uma ungakwazi ukukhokha, sicela uhlole ukuthi ngabe kukhona yini inkinga ngenzwa. Ngaphansi kwesimo sokuqinisekisa ukuthi ukuphuma kwenzwa kujwayelekile (umzimba wesikali uzinzile), amaphutha avamile ephaneli yezinsimbi akhiyiwe, ngokuvamile i-amplifier yokusebenza kanye nesekethe yokunikezela amandla okuguqulwa kwe-A/D kunezinkinga. (2) Ukuhlaziywa kwamaphutha avamile okulinganisa okungalungile. Bheka ukuthi inani lekhodi yangaphakathi lizinzile, ukuthi kukhona ukungqubuzana engxenyeni ngayinye yenzwa, ukuthi ngabe ukunikezwa kwamandla okulawulwayo okulungisekayo kuzinzile, nokuthi ngabe isekethe yokunikeza amandla ijwayelekile ngesikhathi sokusebenza. Izisindo zibona ukuthi isikali esinezinyawo ezine sepani yokulinganisa silingana. Yenza ukuhlaziywa okuyingxenye noma ukulinganisa isisindo sephaneli yethuluzi njengoba kuboniswe emiyalweni yokusebenzisa.

(3) Amaphutha avamile lapho isikali sepulatifomu kagesi singakwazi ukuvulwa yiwona okuqala ukuhlonza izinkinga ezibangelwa yi-non-fuse, iswishi yamandla eyinhloko, ipulaki yamandla kanye neswishi yokudlulisa i-voltage esebenzayo, bese uhlola ukuthi i-transformer inayo yini i-AC current input kanye ne-AC current output. Uma iphaneli yezinsimbi iqukethe ibhethri elishajekayo, ungasusa ibhethri bese uliqala nge-AC switching power supply ukuze uhlole ukuthi i-voltage yebhethri yemoto ayanele yini. Okulandelayo, hlola ukuthi isekethe ye-inverter, isekethe yamandla alawulwayo kanye nesekethe ye-optocoupler yolwazi lokubonisa akujwayelekile.

Uma kungekho nkinga, hlola ukuthi i-CPU kanye nesekethe yamandla enamathiselwe kushile yini.
