Ni irihe tandukaniro riri hagati ya metero ya ultrasonic na metero ya radar?

Urwego nimwe mubintu byingenzi bigamije kugenzura ibikorwa byinganda.Mu rwego rwo gukomeza gupima tanki zitandukanye, silos, ibidendezi, nibindi, biragoye kugira ibikoresho byo murwego rushobora kuzuza ibisabwa byose kubera imiterere myinshi yimiterere.

Muri byo, ibipimo bya radar na ultrasonic bikoreshwa cyane mubikoresho byo gupima bidahuza.None, ni irihe tandukaniro riri hagati ya metero ya radar na metero ya ultrasonic?Ni irihe hame ryubwoko bubiri bwo gupima?Ni izihe nyungu za metero ya radar na metero ya ultrasonic?

Ubwa mbere, metero ya ultrasonic

Mubisanzwe twita amajwi yumurongo hamwe ninshuro zirenga 20kHz ultrasonic wave, ultrasonic wave ni ubwoko bwimashini ya mashini, ni ukuvuga kunyeganyega kwa mashini muburyo bwa elastique mugihe cyo gukwirakwiza, irangwa numurongo mwinshi, uburebure buke, buto diffaction phenomenon, hamwe nubuyobozi bwiza, birashobora guhinduka imirasire no gukwirakwizwa.

Ultrasonic attenuation mumazi na solide ni nto cyane, kubwibyo ubushobozi bwo kwinjira burakomeye, cyane cyane mumashanyarazi ya opaque, ultrasonic irashobora kwinjira muri metero icumi z'uburebure, guhura n’umwanda cyangwa intera bizagira ibitekerezo bigaragara, gupima urwego rwa ultrasonic ni ugukoresha iyi ngingo.

Muri tekinoroji yo gutahura ultrasonic, niyo yaba igikoresho icyo ari cyo cyose cyitwa ultrasonic, birakenewe guhindura ingufu z'amashanyarazi mu kirere cya ultrasonic, hanyuma ugakira mu bimenyetso by'amashanyarazi, igikoresho cyo kurangiza iki gikorwa cyitwa ultrasonic transducer, kizwi kandi nka probe.

Iyo ukora, transducer ya ultrasonic ishyirwa hejuru yikintu cyapimwe kandi ikarekura ultrasonic wave hepfo.Umuhengeri wa ultrasonic unyura mu kirere, ugaragarira inyuma iyo uhuye hejuru yikintu cyapimwe, kandi wakiriwe na transducer ugahinduka ikimenyetso cyamashanyarazi.Nyuma yo kumenya iki kimenyetso, igice cya elegitoroniki cyerekana gihindura ikimenyetso cyurwego rwo kwerekana no gusohoka.

Babiri, metero y'urwego rwa radar

Uburyo bwo gukora bwa metero ya radar ni kimwe nubwa metero ya ultrasonic, na metero ya radar nayo ikoresha uburyo bwo kohereza - kwerekana - kwakira uburyo bwakazi.Itandukaniro nuko gupima metero ya radar ultrasonic urwego rushingiye cyane cyane kuri transducer ya ultrasonic, mugihe metero yo murwego rwa radar yishingikiriza kumutwe mwinshi na antene.

Urwego rwa Ultrasonic rukoresha imashini zikoresha imashini, mugihe urwego rwa radar rukoresha ultra-high frequency (nyinshi G kugeza kuri mirongo ya G Hertz) imiraba ya electronique.Umuhengeri wa electromagnetic ugenda ku muvuduko wurumuri, kandi igihe cyurugendo gishobora guhinduka ikimenyetso cyurwego rwibikoresho bya elegitoroniki.

Ubundi metero isanzwe ya radar ni metero iyobowe na metero ya radar.

Kuyobora umurongo wa radar urwego rwa metero ni urwego rwa radar rushingiye ku gihe cyerekana indangarubuga (TDR).Impanuka ya electromagnetic ya metero ya radar ikwirakwiza kumurongo wicyuma cyangwa probe kumuvuduko wurumuri.Iyo ihuye nubuso bwikigereranyo cyapimwe, igice cyimpiswi ya metero ya radar igaragazwa kugirango ikore echo hanyuma igasubira mubikoresho byo gutangiza impiswi munzira imwe.Intera iri hagati ya transmitter hamwe nubuso bwapimwe buringaniye buringaniye nigihe cyo gukwirakwizwa kwimpiswi ibarwa uburebure bwurwego rwamazi.

Icya gatatu, ibyiza nibibi bya radar na metero ya ultrasonic

1. Ultrasonic ubunyangamugayo ntabwo ari bwiza nka radar;

2. Bitewe nubusabane buri hagati yubunini bwa antenne, metero ya radar ifite metero ndende ni nto kandi byoroshye kuyishyiraho;

3. Kuberako radar inshuro nyinshi, uburebure bwumurongo ni bugufi, kandi haribintu byiza bigaragarira hejuru yunamye;

4. Radar gupima impumyi agace gato ni ultrasonic;

5. Bitewe numurongo mwinshi wa radar, urumuri rwa radar Inguni ni nto, ingufu ziba zegeranye, kandi ubushobozi bwa echo burazamuka mugihe bifasha kwirinda kwivanga;

6. Ugereranije na metero yo murwego rwa ultrasonic ukoresheje imiraba yubukanishi, radar mubusanzwe ntabwo yibasiwe na vacuum, imyuka y'amazi mukirere, umukungugu (usibye grafite, ferroalloy nindi mivu ndende ya dielectric), ubushyuhe nimpinduka zumuvuduko;
