Khawube nomfanekiso-ngqondweni woku: Yintsasa yasebusika ebandayo, yaye sele uza kuqalisa uhambo lwakho lwemihla ngemihla. Njengoko utsibela kwinqwelo-mafutha yakho kwaye uqalise i-injini, i-beep engamkelekanga iphula ukuthula: isilumkiso esicaphukisayo soxinzelelo lwetayara. Ujonga amatayara, kodwa yonke into ibonakala ilungile. Kuqhubekani?
Kwiimeko ezininzi, akuyongxaki yokwenyani kuxinzelelo lwetayara lakho. Umtyholi emva kwesi silumkiso sobuxoki yintsebenziswano phakathi kweqondo lokushisa kunye nenzwa yoxinzelelo lwesondo. Njengoko iqondo lobushushu liyehla, umoya ongaphakathi kwamatayara uyacutheka, nto leyo ebangela ukuncipha kancinane koxinzelelo. Nangona kunjalo, phantsi kweemeko eziqhelekileyo, oku kwehla koxinzelelo kunokunganeli ukuqalisa inkqubo ye-alamu.
Kodwa njengalo naliphi na icandelo le-elektroniki, izinzwa zoxinzelelo lwetayara zinokuchatshazelwa kukutshintsha kobushushu. Kwiindawo ezibandayo, uvakalelo lwe-sensor kunye nokuchaneka kunokuncipha, okukhokelela ekutolikeni ngempazamo utshintsho oluncinci loxinzelelo njengamaconsi abalulekileyo, okubangela i-alamu yobuxoki ephazamisayo.
Lo mcimbi ubalaselisa ukubaluleka kweukuzinza kwenzwa yoxinzelelo. Inzwa ezinzileyo iya kugcina ukuchaneka kwayo kunye novelwano kuluhlu olubanzi lobushushu, iqinisekisa ukufundwa koxinzelelo oluthembekileyo lwetayara nakwiimeko ezinzima zasebusika.
Yintoni uZinzo lweSensoni yoxinzelelo?
Ngokutsho kwe-ISO17034:2016, ukuzinza kwenzwa yoxinzelelo yiparameter ebalulekileyo yokuqinisekisa ukusebenza okuchanekileyo nokuthembekileyo kweenkqubo zokulinganisa uxinzelelo. Ibhekisela kumandla oluvo lokugcina iimpawu zayo zokusebenza kwixesha elithile xa ijongene nemingeni yokusingqongileyo kunye nokusebenza. Eli xesha lidla ngokuba ngunyaka omnye. Uzinzo luchaphazela ukuchaneka kwenzwa,ukuphinda-phinda, kunye nobomi bubonke, iyenza ibaluleke kakhulu kwizicelo ukusuka kwimizi-mveliso ukuya kwizixhobo zonyango.
Ukuzinza kwexesha elide, Ukuzinza kwexesha elifutshane, Ukuphindaphinda
Uzinzo lwexesha elideUkuzinza kwexesha elide kubhekiselele kwisakhono senzwa ukugcina ukuchaneka kwayo kunye nokuhambelana ngexesha elongezelelweyo. Umzekelo, inzwa enozinzo lwexesha elide lwe-0.01% isikali esipheleleyo ngonyaka inokukhukuliseka kuphela nge-1.5 Pa kwixesha le-15 leminyaka yokusetyenziswa. Oku kuthetha ukuba ukufundwa kwenzwa kuhlala kuthembekile nasemva kokusetyenziswa kwexesha elide.
Uzinzo lwexesha elifutshaneUzinzo lwexeshana elifutshane lubandakanya ukusebenza koluvo olungaguquguqukiyo kwixesha elifutshane (umzekelo, iiyure okanye iintsuku). Uzinzo lwexeshana elifutshane lubalulekile kwizicelo ezifuna imilinganiselo ekhawulezileyo nechanekileyo. Ukusebenza kwexesha elifutshane lenzwa kubonakalisa uyilo lwayo kunye nomgangatho wokuvelisa.
UkuphindaphindaUkuphindaphinda kubhekiselele ekungqineni kokufundwa kwenzwa xa kulinganiswa amaxesha amaninzi phantsi kweemeko ezifanayo. Inzwa ephindaphindwayo kufuneka ibonise iziphumo ezisondele kakhulu kumlinganiselo ngamnye, iqinisekisa ukuthembeka kunye nokuchaneka kwenkqubo yokulinganisa. Ukuphindaphinda okulungileyo kuthetha ukuba inzwa inokubonelela ngeziphumo ezihambelanayo phantsi kweemeko ezahlukeneyo zokusebenza.
Zero Drift kunye noSensitivity Drift
- Zero Drift:I-Zero drift ibhekisa kutshintsho kwisiphumo senzwa xa kungekho xinzelelo lusetyenziswayo. I-Zero drift inokubangela ukuba isiseko somlinganiselo sitshintshe, sichaphazela ukuchaneka. Oku kukhukuliseka kunokubangela utshintsho kwimo engqongileyo okanye kusetyenziso lwexesha elide.
- UkuSensitivity Drift:I-Sensitivity drift ibhekiselele kutshintsho kwisakhono sokukhupha i-sensor xa kusetyenziswa uxinzelelo olufanayo. I-Sensitivity drift ichaphazela impendulo ye-sensor kutshintsho loxinzelelo, ekhokelela ekuphambukeni komlinganiselo.
Uzinzo lobushushu
Ukuzinza kobushushu kubhekiselele kutshintsho lwentsebenzo yenzwa phantsi kwemeko ezahlukeneyo zobushushu. Ukutshintsha kweqondo lokushisa kunokubangela ukuba izixhobo zenzwa zande okanye zekhontrakthi, ezichaphazela umphumo wayo. Kulungileuzinzo lobushushukuthetha ukuba isivamvo sinokugcina umlinganiselo wokwenziwa komlinganiselo phezu koluhlu olubanzi lobushushu, nto leyo ibaluleke kakhulu kwizinzwa ezisebenza kwindawo ezinobushushu obugqithisileyo.
Imiba echaphazela ukuzinza kweSensor yoxinzelelo
- Imiba yokusingqongileyo:Ukuvezwa kwiqondo lobushushu, ukufuma, kunye nongcoliseko kunokubangela inzwa yenzwa kunye nokunciphisa ukuchaneka. Ukutshintsha kobushushu obugqithisileyo kunokubangela ukuba izixhobo zenzwa zande okanye zivumelane, ukufuma okugqithisileyo kunokugqwala okanye amacandelo enzwa yesiphaluka esifutshane, kwaye ukungcola kunokuvala izinto ezibuthathaka zenzwa, ezichaphazela ukusebenza okuqhelekileyo.
- Uxinzelelo lomatshini:Ukungcangcazela, ukothuka, kunyeuxinzelelo lomatshiningexesha lofakelo kunokuchaphazela ingqibelelo yesakhiwo senzwa. Ukungcangcazela kwexesha elide kunokukhulula okanye konakalise amacandelo angaphakathi, ukutshatyalaliswa okukhulu kunokonakalisa ngokuthe ngqo inzwa, kwaye ukufakela okungafanelekanga kunokuguqula okanye ukulungelelanisa inzwa, echaphazela ukuchaneka nokuzinza.
- Ukuguga:Izinto eziphathekayo kunye namacandelo aguga ngokuhamba kwexesha, okuchaphazela ukuzinza. Izixhobo zoluvo zinokuba nokudinwa, ukunxiba, okanye ukuthotywa kokusebenza emva kokusetyenziswa kwexesha elide. Esi siphumo sokuguga sinokunciphisa uvakalelo lwenzwa, isantya sokuphendula ngokukhawuleza, kunye nokunyusa impazamo, echaphazela ukuzinza kwexesha elide kunye nokuthembeka.
- Utshintsho lobushushu:Ukutshintsha kweqondo lobushushu kubangela ukuba izixhobo zenzwa zande kwaye zikhontrakthi, zifuna ukusebenzaimbuyekezo yobushushuubuchule. Ukusebenza kwenzwa kunokwahluka kumaqondo obushushu ahlukeneyo, afana ne-zero drift kunye nokutshintsha kovakalelo. Iindlela ezisebenzayo zembuyekezo yeqondo lokushisa, njengokusebenzisa i-sensor yereferensi, ukulungiswa kwe-algorithms, kunye nokukhetha i-coefficient yokwandisa i-thermal ephantsi, kuyimfuneko ukuqinisekisa ukuba inzwa igcina ukuchaneka okuphezulu kunye nokuzinza phantsi kweemeko ezahlukeneyo zokushisa.
