Umgaqo wokulinganisa
Indlela yokwahluka kwexesha: kukho umahluko wexesha xa amaza esandi esasaza umgama ofanayo kulwelo oluphezulu noluphezulu, kwaye umahluko kwixesha lokusasazeka unxulumene nesantya sokuhamba komzimba wokuhamba okulinganisiweyo. Isantya sokuhamba kolwelo sifunyanwa ngokulinganisa lo mahluko wexesha, kwaye emva koko isantya sokuhamba siyabalwa.
Indlela yeDoppler: Ngokusekelwe kumgaqo weDoppler kwi-acoustics, ukutshintshwa kwamaza omsindo phakathi kwezandi ezibonakalisiweyo kunye nezandi ezikhutshwayo kuyafunyanwa ukuze kuchongwe isantya samaqhekeza ahambayo kulwelo, ukuze kufunyanwe ngokungathanga ngqo isantya sokuhamba kunye nesantya sokuhamba kolwelo, nto leyo efuna ukuba kubekho izinto ezixhonyiweyo ezifana namaqamza kunye namaqhekeza aqinileyo emanzini ukuze kuboniswe umqadi we-ultrasonic.
Ulwelo olusebenzayo
Indlela yokwahluka kwexesha: ifanelekile ukulinganisa ukungcola okucocekileyo, okuncinci kolwelo, njengeoyile ekrwada, ioyile enzima, amanzi acocekileyo, amanzi angena ion, izinyibilikisi zeekhemikhali, njl.njl., ukuba ulwelo lunenani elikhulu lamaqamza okanye ukungcola okuqinileyo, luya kuthintela ukusasazeka okuqhelekileyo kwamaza e-ultrasonic, okuchaphazela ukuchaneka kokulinganisa.
Indlela yeDoppler: isetyenziswa rhoqo ukulinganisa ulwelo olunamafu oluqulethe amaqamza, amasuntswana aqinileyo kunye nokunye ukungcola, okufana nelindle, udaka, umxube wamanzi eoyile, njl.njl., esetyenziswa kakhulu emanzini endalo, unyango lwamanzi amdaka kwimizi-mveliso nakwezinye iindawo.
Ukuchaneka kokulinganisa
Indlela yokwahluka kwexesha: ukuchaneka kuphezulu kakhulu, ukuya kuthi ga kwi-±0.5%, kwaye ukuchaneka kokulinganisa kwayo kuchaphazeleka kukuchaneka kwezixhobo ze-elektroniki zokucubungula isignali kunye nokuzinza kwesantya sesandi.
Indlela yeDoppler: Ukuchaneka ngokubanzi kuphantsi kunendlela yokwahluka kwexesha, ngokuqhelekileyo malunga ne-±2%, kuba iziphumo zayo zokulinganisa zisekelwe kwisignali esasazekileyo yamasuntswana axhonyiweyo okanye amaqamza kulwelo, kwaye ukusasazwa kunye nokuhamba kwezi suntswana kusenokungalingani, nto leyo eya kuba nefuthe elithile ekuchanekeni kokulinganisa.
Iimfuneko zokufaka imibhobho
Indlela yokwahluka kwexesha: imeko yokuhamba kolwelo kumbhobho ingqongqo ngakumbi, ulwelo kufuneka luzinze ngakumbi kwaye lufane, kwaye icandelo lombhobho othe tye lineemfuno ezithile, ubude becandelo lombhobho othe tye ongaphezulu bungaphantsi kwezihlandlo ezili-10 ububanzi becandelo lombhobho othe tye osezantsi bungaphantsi kwezihlandlo ezi-5 ububanzi bombhobho.
Indlela yeDoppler: Iimfuneko zecandelo lombhobho azingqongqo kangako, indawo yokufakela iguquguquka ngakumbi, kwaye iphethini yokuhamba kombhobho ayichaphazeleki kangako.
Ulwakhiwo lwenzwa kunye nofakelo
Indlela yokwahluka kwexesha: isibini esinye okanye ngaphezulu seesensa zihlala zisetyenziswa, zifakelwa ngokulandelelanayo kumbhobho ongaphezulu nongaphantsi, kwaye ulwalathiso lokudlulisela nokwamkela lwesensa kufuneka lugcine i-Angle ethile kunye ne-axis yombhobho ukuqinisekisa ukuba ixesha lokudlulisela lesignali ye-ultrasonic lilinganiswa ngokuchanekileyo. Ngexesha lokufakela, isensa kufuneka ilungelelaniswe kwaye ilungiswe ukuqinisekisa uzinzo lokudlulisela isignali.
Indlela yeDoppler: Ukusetyenziswa ngokubanzi kwesensor enentloko enye, kubandakanya ukuthumela nokufumana iikristale zepiezoelectric, kunokufakelwa eludongeni lwangaphandle lombhobho, okanye kufakwe ngqo xa kudibene nolwelo, kulula ukuyifaka, kwaye akuyi kubangela umonakalo kumbhobho.
Ubuchule bokulwa nokuphazamiseka
Indlela yokwahluka kwexesha: kulula ukuchaphazeleka kukungcangcazela kwemibhobho, utshintsho lobushushu bolwelo kunye noxinano kunye nezinye izinto, ukungcangcazela kwemibhobho kunokukhokelela ekuphambukeni kwindawo yenzwa, okuchaphazela ukuchaneka kokulinganisa, kwaye utshintsho lobushushu kunye noxinano luya kubangela utshintsho lwesantya sesandi, imbuyekezo yobushushu kunye nezinye iindlela ziyafuneka ukuphucula ukuchaneka kokulinganisa.
Indlela yeDoppler: amandla aqinileyo okulwa nokuphazamiseka, ayinamvakalelo yokungcangcazela kwemibhobho, kwaye kuba umgaqo wayo wokulinganisa usekelwe kutshintsho lwesangqa seDoppler, kwaye ubushushu kunye noxinano lolwelo alunabudlelwane buninzi, ngoko ke lusenokugcina uzinzo oluhle phantsi kweemeko zokusebenza ezinzima.
Uluhlu lokulinganisa
Indlela yokwahluka kwexesha: Uluhlu lokulinganisa lubanzi, lunokulinganisa isantya sokuhamba esiphantsi ukuya kulwelo oluphezulu lokuhamba, lufanelekile kwiindidi ezahlukeneyo zedayamitha zepayipi, kodwa kwiidayamitha ezinkulu zepayipi, ukulinganisa isantya sokuhamba okuphezulu, kunokufuna amandla aphezulu okuhambisa kunye netekhnoloji yokucubungula isignali enzima ngakumbi.
Indlela yeDoppler: ngokubanzi ifanelekile ekulinganisweni kolwelo oluhamba ngesantya esiphantsi nesiphakathi, kulwelo oluhamba ngesantya esiphezulu, kuba ubudlelwane phakathi kokutshintsha kwesantya seDoppler kunye nesantya sokuhamba asihambelani, kunokukhokelela ekwandeni kwempazamo yokulinganisa.
