- Umehluko oyisisekelo phakathi kokunemba, ukunemba, isixazululo, kanye nokuzwela ekulinganisweni kwedatha.
- Ukuhlaziywa kwezici zangaphandle nezobuchwepheshe ezingashintsha ukuthembeka kwenzwa, njengokushisa nomsindo kagesi.
- Ukubaluleka kokukhetha okufanele kanye nokulinganisa ngezikhathi ezithile ukuqinisekisa ukuphepha nokusebenza kahle kwezinqubo ezenzakalelayo.
Uma sikhuluma ngokuzenzakalela kwezimboni, sivame ukuhlangana negama elithi " ukunemba kwenzwa ," yize ngezinye izikhathi lisetshenziswa ngokunganaki. Eqinisweni, ukuba namathuluzi alinganisa ngokunembile akuyona nje into eyenzeka ngobuchwepheshe; kuyisisekelo sokuvimbela noma yimuphi umugqa wokukhiqiza ukuthi uphele enhlekeleleni, okuvumela ukulawula okunembile kobukhulu nezikhundla zezingxenye.
Ukuze siqonde ngqo ephuzwini, kubalulekile ukuqonda ukuthi izinzwa zisebenza njengesandiso sezinzwa zethu , kodwa ezingeni likagesi. Kusukela kwezolimo kuya ekuhloleni isikhala kanye nezokwelapha, la madivayisi asivumela ukuthi siqaphe izinto eziguquguqukayo iso lomuntu elingenakuzibona, siqinisekise ikhwalithi yomkhiqizo eqhubekayo futhi sivimbele ukuphuka komshini ngenxa yamaphutha okufunda.
Imiqondo eyinhloko: Ungadidanisi ukunemba nokunemba
Ukuze siqale ibhizinisi, sidinga ukulungisa iphutha elivamile: umehluko phakathi kokunemba nokunemba. Cabanga ngokuphonsa imicibisholo ebhodini le-dart; ukunemba kusho ukushaya isikhungo esiqondile, kuyilapho ukunemba kusho ukuthi yonke imicibisholo ifika endaweni efanayo , noma ngabe leyo ndawo akuyona isikhungo. Ezweni lezinzwa, ukunemba kubhekisela ekuhambisaneni nasekuphindaphindweni kwamanani alinganisiwe, kuyilapho ukunemba kuwukuthi lelo nani liseduze kangakanani nedatha yangempela.
Kulokhu kumele sengeze isixazululo kanye nokuzwela . Ukuzwela ngokuyisisekelo yisilinganiso esiphakathi koshintsho kokukhiphayo kanye noshintsho kokufaka; uma inzwa inozwela kakhulu, izobona ukuhlukahluka okuncane, yize lokhu ngezinye izikhathi kungalimaza ukuzinza. Ngakolunye uhlangothi, isixazululo yikhono lokubona ushintsho oluncane kakhulu olungenzeka . Uma inani lokufaka lishintsha kodwa inzwa ingasabeli kuze kube yilapho ushintsho lukhulu, sikhuluma ngomkhawulo wesisombululo sayo, esivame ukuxhunyaniswa nekhwalithi yesiguquli se- A/D (i-analog-to-digital).
Izinhlobo zezinzwa ngokwezidingo zokulinganisa
Kuye ngokuthi yini okudingeka siyiqaphe esitshalweni, kunezindlela zobuchwepheshe ezahlukene ezitholakalayo. Isibonelo, ama-profilometer e-laser abaluleke kakhulu ekuskeneni izinto ku-2D kanye ne-3D, okusivumela ukuthi sihlaziye ama-engeli nezindawo ngemininingwane emangalisayo. Uma sifuna isivinini kanye nokunemba ekulinganisweni kwebanga, izinzwa zokuhambisa i -laser ezisekelwe ku-triangulation ziyisinqumo esifanele.
- Ama-micrometer optical: Kubalulekile ekulinganiseni ububanzi nobubanzi ku-1D kanye ne-2D, ukuqinisekisa ukuthi izingxenye zilingana kahle.
- Izinzwa ezivuselelayo: Uchwepheshe ezintweni zensimbi, ulinganisa ubukhulu kanye nokungafani ngesikhathi sangempela.
- Izinzwa ze-LVDT: Kulabo abadinga ukunemba okukhulu, njengoba bengakwazi ukufeza ukulungiswa kufika ku-0.1 μm, okwenza zilungele ukuqhathanisa ngasikhathi sinye.
Izici ezihlola ukunemba kwenzwa
Akulula njengokufaka inzwa bese uyikhohlwa; izici zemvelo zingabangela ukufundwa kuphele. Isitha sokuqala, ngaphandle kokungabaza, izinga lokushisa . Ukushisa kubangela ukwanda kokushisa ezingxenyeni zangaphakathi, okungaphazamisa isignali. Eqinisweni, ukweqa okungu-10°C kungashintsha umphumela ngo-0,5% uma imishini ingenayo isinxephezelo esanele sokushisa.
Kumelwe futhi siqaphele ukuhambisana kwemidiya . Uma uketshezi lunamandla noma lungahambisani ne-diaphragm yenzwa yokucindezela, luzogcina lulimaze, futhi ukufundwa ngeke kuthembeke. Ezinye izinkinga ezivamile zifaka phakathi umsindo kagesi kanye nokuphazamiseka kwe-electromagnetic (EMI) , okonakalisa isignali kagesi, kanye nokucindezeleka komshini okubangelwa ukuqinisa amantongomane ngesikhathi sokufakwa.
Indlela yokuthuthukisa ukusebenza nokugwema amaphutha
Ukuze uhlelo lusebenze kahle, kubalulekile ukukhetha inzwa enobubanzi bokulinganisa obufanele . Ukusebenzisa inzwa enobubanzi obubanzi kakhulu ekulinganisweni okuncane kuzoholela ekulahlekelweni kokunemba. Ngaphezu kwalokho, kubalulekile ukusebenzisa ukulinganisa okuvamile (njalo ezinyangeni eziyi-6 kuya kweziyi-12) ukuze kulungiswe ukukhukhuleka okubangelwa ukuguguleka nokusetshenziswa okuqhubekayo.
Elinye isu elihlakaniphile ukusebenzisa izinhlelo zokuvikela ukuphazamiseka kanye nokusekela phansi ukuvimbela umsindo kagesi ukuthi ungaphazamisi idatha. Kuma-sensor okucindezela, ukukhetha imishini echaza ibhendi yamaphutha okushisa amancane kuyindlela engcono kakhulu yokuqinisekisa ukuzinza kohlelo kungakhathaliseki ukuthi isimo sezulu sinjani efektri.
Izinzuzo zangempela zokulinganisa okunembile
Ukulawula konke lokhu akuyona nje indaba yobuchwepheshe, kodwa futhi nemali nokuphepha. Ukulinganisa okunembile kuvumela ukutholakala kusenesikhathi kokucindezela ngokweqile , kuvimbele ama-boiler noma amapayipi ukuthi angaqhumi, okuyinto ebalulekile ezindaweni zezimboni nezokwelapha. Ngaphezu kwalokho, kunciphisa kakhulu imfucuza yezinto ezibonakalayo , njengoba kugwema ukukhiqizwa kwezingxenye ezinephutha ebezizolahlwa ngaphandle kwalokho.
Ezingeni lokusebenza, lokhu kunemba kuholela ekuzenzakalelayo okubushelelezi kakhulu , lapho ama-valve nama-piston esebenza khona ngesikhathi esifanele. Lokhu akugcini nje ngokwandisa isikhathi sokuphila komshini ngokuvimbela ukucindezeleka okungadingekile, kodwa futhi kunciphisa isidingo sokungenelela okuqhubekayo ngesandla, ngaleyo ndlela kuthuthukisa izindleko zokulungisa zesikhathi eside .
Ukuphathwa okufanele kokunemba kwenzwa kanye nokuphindaphindeka, kanye nokuqapha njalo iziguquguquko zemvelo kanye nokulinganisa okuqinile, yikho okwenza umehluko phakathi kokukhiqiza okuphakathi nokusebenza kahle kakhulu. Ngokuqonda ukusebenzisana phakathi kokuxazululwa, ukuzwela, kanye nezici zangaphandle, izinkampani zingaqinisekisa ukuzinza kwenqubo, ziqinisekise ukuphepha komqhubi, futhi zikhulise inzuzo yezinhlelo zazo ezizenzakalelayo.
