Njengeyunithi yokulawula eyinhloko, ukwakheka kanye nomsebenzi we-I-vortex flowmeteribhodi lesifunda lithinta ngqo ukusebenza kwe-flowmeter. Ngokusekelwe kumgomo wokusebenza we-vortex flowmeter (ukuthola ukugeleza koketshezi okusekelwe ku-Karman vortex phenomenon), izinzuzo eziyinhloko zebhodi lesifunda zingafingqwa kanjena ezicini zezimpawu zobuchwepheshe, izinzuzo zokusebenza, kanye nenani lesicelo:
Ukutholwa okunembile kwamasignali amaza aphezulu:
Ibhodi lesifunda lihlanganisa amamojula we-analog-to-digital conversion (ADC) anesivinini esiphezulu kanye nama-chips okucubungula isignali yedijithali (DSP), angathwebula amasiginali abuthakathaka (ngokuvamile amashumi kuya ezinkulungwaneni ze-Hz) akhiqizwa amajeneretha e-vortex ngesikhathi sangempela. Ngokuhlunga, ukukhulisa, kanye nama-algorithms okunciphisa umsindo, iphutha lokutholwa kwesignali liqinisekiswa ukuthi lingaphansi kuka-0.1%, lihlangabezana nezidingo zokulinganisa ezinembayo eziphezulu (njengokunemba kokulinganisa okungu-± 1% R).
Isinxephezelo esingaqondile kanye nama-algorithms ahlakaniphile:
I-microprocessor (MCU) eyakhelwe ngaphakathi ingalungisa ithonya lokuminyana koketshezi kanye nezinguquko ze-viscosity emiphumeleni yokulinganisa ngokusebenzisa ama-algorithms wesinxephezelo sezinga lokushisa/nokucindezela, ivumelane nezimo zokusebenza ezihlukene (ezifana nezinga lokushisa eliphezulu, ukucindezela okuphezulu, nendawo eguquguqukayo), futhi ithuthukise ukuqina kokulinganisa ezindaweni eziyinkimbinkimbi.
Ukwethenjelwa okuphezulu kanye nomklamo wokulwa nokuphazamiseka
Ukuthuthukiswa kokunqanda ukuphazamiseka kwezingxenyekazi zekhompuyutha:
Ukwamukela ukwakheka kwe-PCB enezingqimba eziningi, ukuvikela i-electromagnetic (okufana nesembozo sokuvikela insimbi), ukuhlunga amandla (isifunda sokuhlunga i-LC, imojuli yamandla ehlukanisiwe) kanye nobuchwepheshe bokuhlukanisa isignali (i-optocoupler isolation, ukudluliswa kwesignali ehlukile), imelana ngempumelelo nokuphazanyiswa kwe-electromagnetic (EMI), ukuphazamiseka kwamafrikhwensi omsakazo (RFI) nomsindo wamandla kumasayithi wezimboni, kuqinisekisa ukuthikamezeka kwezimoto ezisebenza ngamandla.
Ithempelesha ebanzi nokuguquguquka kwengcindezi ebanzi:
Khetha izingxenye ze-electronic zebanga lezimboni (ezifana nezinga lokushisa elizungezile: -30 ° C kuya ku-+65C; umswakama ohlobene: 5% kuya ku-95%; Ingcindezi yomoya: 86KPa ~ 106KPa, imojula yokufaka kagesi ebanzi), isekela okokufaka kwamandla ka-DC 12~24V noma i-AC 220V, ifanele indawo enkulu, ukudlidliza kwangaphandle, ukudlidliza kwangaphandle.
Ibhodi lesifunda leI-vortex flowmeterifinyelela ukunemba, ukuzinza, kanye nokuvumelana nezimo esilinganisweni sokugeleza ngezinzuzo ezifana nokucubungula isignali enembayo, ikhono eliqinile lokulwa nokuphazamiseka, ukuhlanganiswa kokusebenza okuhlakaniphile, kanye nomklamo wamandla aphansi. Isetshenziswa kabanzi ezimbonini ezifana namakhemikhali e-petrochemicals, amandla, amanzi, i-metallurgy, njll., ikakhulukazi ezimweni eziyinkimbinkimbi zokusebenza kanye nezinhlelo ezizenzakalelayo. Inani layo eliyinhloko lisekulungiselelweni ngokubambisana kwesofthiwe nezingxenyekazi zekhompuyutha ukuze kuthuthukiswe ukusebenza kwamathuluzi kuyilapho kunciphisa ukusetshenziswa komsebenzisi nezindleko zokuyilungisa.
