Waa maxay faraqa u dhexeeya mitirka heerka ultrasonic iyo mitirka heerka radar?

Heerku waa mid ka mid ah halbeegyada bartilmaameedka muhiimka ah ee la socodka geeddi-socodka warshadaha.Qiyaasta heerka joogtada ah ee taangiyada kala duwan, silos, barkadaha, iwm, way adag tahay in la helo qalab heerkul ah oo buuxin kara dhammaan shuruudaha shaqada sababtoo ah noocyada kala duwan ee xaaladaha goobta.

Waxaa ka mid ah, radar iyo cabbirada heerka ultrasonic ayaa si weyn loogu isticmaalaa aaladaha cabbiraadda ee aan xidhiidhka ahayn.Haddaba, waa maxay faraqa u dhexeeya mitirka heerka radar iyo mitirka heerka ultrasonic?Waa maxay mabda'a labadan nooc ee cabbiraadda?Waa maxay faa'iidooyinka mitirka heerka radar iyo mitirka heerka ultrasonic?

Marka hore, mitirka heerka ultrasonic

Waxaan guud ahaan ugu yeernaa mowjadda dhawaaqa leh inta jeer ee in ka badan 20kHz mawjada ultrasonic, hirarka ultrasonic waa nooc ka mid ah hirarka farsamada, taas oo ah, gariirka farsamada ee dhexdhexaadiyaha laastikada ee habka faafinta, waxaa lagu gartaa soo noqnoqoshada sare, hirarka gaaban, yar yar. ifafaale kala fogaansho, iyo toosin wanaagsan, waxay noqon kartaa iftiin iyo faafin jihayn.

Attenuation Ultrasonic ee dareeraha iyo adkaha waa mid aad u yar, sidaas darteed awoodda wax gelinta waa mid xooggan, gaar ahaan adkaha iftiinka iftiinka, ultrasonic wuxuu geli karaa tobanaan mitir oo dherer ah, wuxuu la kulmaa wasakh ama interfaces waxay yeelan doonaan milicsi muhiim ah, cabbirka heerka ultrasonic waa isticmaalka sifadan.

Tignoolajiyada ogaanshaha ultrasonic, iyada oo aan loo eegin nooca qalabka ultrasonic, waa lagama maarmaan in tamarta korantada loo beddelo qiiqa ultrasonic, ka dibna dib loogu celiyo calaamadaha korantada, aaladda lagu dhammaystiro hawshan waxaa loo yaqaannaa transducer ultrasonic, oo sidoo kale loo yaqaan baaritaanka.

Marka la shaqaynayo, transducer-ka ultrasonic waxa la dhigayaa meel ka sarraysa shayga la cabbiray waxana uu soo daayaa mowjadda ultrasonic hoos.Hirarka ultrasonic wuxuu dhex maraa dhexdhexaadiyaha hawada, dib ayuu u milicsadaa marka uu la kulmo oogada shayga la cabbiray, waxaana helay transducer oo u beddela calaamad koronto.Ka dib markii la ogaado calaamaddan, qaybta ogaanshaha elektaroonigga ah waxay u beddeshaa calaamad muujinaysa muujinta iyo soo saarista.

Laba, mitir heerka raadaarka

Habka hawlgalka ee mitirka heerka radar wuxuu la mid yahay kan mitirka heerka ultrasonic, iyo mitirka heerka radar wuxuu kaloo isticmaalaa gudbinta - ka tarjumaysa - helitaanka habka shaqada.Farqiga u dhexeeya ayaa ah in cabbiraadda mitirka heerka radar ultrasonic inta badan ay ku tiirsan tahay transducer ultrasonic, halka mitirka radarku uu ku tiirsan yahay madaxa soo noqnoqda sare iyo anteenada.

Mitirrada heerka Ultrasonic waxay adeegsadaan mowjado farsamo, halka mitirka raadaarka ay isticmaalaan mowjadaha korantada ee aadka u sarreeya (dhowr G ilaa tobanaan G Hertz).Mowjadaha Electromagnetic-ku waxay ku socdaan xawaaraha iftiinka, wakhtiga safarkana waxa loo beddeli karaa calaamad heersare ah oo ka kooban qaybaha elektaroonigga ah.

mitirka heerka raadaarka kale ee caadiga ah waa mitir heerka radar ee la hagayo.

mitirka heerka mowjadda radar ee la hagayo waa mitir heerka radar oo ku salaysan mabda'a wakhtiga tarjumaadda wakhtiga (TDR).garaaca garaaca korantada ee mitirka heerka raadaarka waxa uu ku faafiyaa fiilada birta ama barista xawaaraha iftiinka.Marka ay la kulanto dusha sare ee dhexdhexaadiyaha la cabbiray, qayb ka mid ah garaaca garaaca mitirka heerka radar ayaa ka muuqanaya si ay u sameeyaan dhawaaq-celin oo ku soo noqda aaladda garaaca garaaca garaaca isla wadada.Masaafada u dhaxaysa gudbiyaha iyo dusha dhexdhexaadka ah ee la qiyaasay waxay la mid tahay wakhtiga faafinta garaaca wadnaha inta lagu jiro taas oo dhererka heerka dareeraha la xisaabinayo.

Saddexaad, faa'iidooyinka iyo khasaarooyinka radar iyo mitirka heerka ultrasonic

1. Saxnimada Ultrasonic maaha mid u fiican sida radar;

2. Xidhiidhka u dhexeeya soo noqnoqda iyo cabbirka anteenada awgeed, mitirka heerka radar ee soo noqnoqda sare ayaa ka yar oo sahlan in la rakibo;

3. Sababtoo ah inta jeer ee radar-ka ayaa sarreeya, mawjada dhererkeedu waa gaaban yahay, waxaana jira milicsi fiican oo ku saabsan sagxadaha adag ee leexsan;

4. Aagga indha la'aanta cabbirka radar waa ka yar yahay ultrasonic;

5. Sababtoo ah inta jeer ee radar-ka sarreeya, xagasha radar-ka waa yar yahay, tamarta ayaa xoogga saaraysa, iyo awoodda dhawaaqa ayaa la xoojiyay iyada oo ku habboon in laga fogaado faragelinta;

6. Marka la barbardhigo mitirka heerka ultrasonic isticmaalaya mowjadaha farsamada, radar asal ahaan ma saameynayso faakuum, uumiga biyaha ee hawada, boodhka (marka laga reebo graphite, ferroalloy iyo boodhka kale ee dielectric sare), heerkulka iyo cadaadiska isbeddelka;
