Isilinganiso sezinga lokungaxhunywana naye singobunye bobuchwepheshe obubalulekile ekuziguquleni ezishintshayo kwezimboni. Le ndlela ivumela ukuqapha kwamazinga oketshezi noma aqinile ethangini, esitsheni noma esiteshini esivulekile ngaphandle kokuxhumana okungokoqobo nendawo ephakathi. Phakathi kwezindlela ezisetshenziswa kakhulu zokungaxhumani amamitha wezinga le-ultrasonic kanye ne-radar. Uma umsebenzisi angathanda ukusebenzisa ukulinganisa okungathintana naye ekulawuleni izinga, ukuqonda ukusebenza kwamageji ezinga le-ultrasonic kanye ne-radar kusiza ukukhetha okufanele esimweni esithile.
Isimiso sokusebenza
Izikali zezinga le-Ultrasonicisebenza ngokukhipha ukuqhuma kwemvamisa ephezulu yamagagasi omsindo ukuze kutholwe ububanzi ukusuka kunzwa kuye phezulu kwendawo ewuketshezi/eqinile. Lawa maza ahamba emoyeni, akhombisa ngaphandle kwendawo ebonakalayo, futhi abuyele kunzwa. Ibanga linganqunywa ngesikhathi esichithwa ohambweni lwamagagasi. Ngakho-ke ithuluzi lisatshalaliswa ebangeni kwesokudla ngenhla kwendawo emaphakathi, ngaphandle kokuthi noma iyiphi ingxenye ithintwe ngokuqondile noma icwiliswe phakathi nendawo.
Izikali zamaleveli eradaisebenzisa amaza kagesi (ama-microwave) esikhundleni somsindo ukuze inqume izinga eliphakathi loketshezi noma eliqinile. Ngokufanayo amasiginali e-microwave akhishelwa endaweni ephakathi bese ayaboniswa futhi abuyiselwe ensimbini. Phakathi nenqubo akukho futhi ukuthintana ngokomzimba phakathi komzimba wensimbi nophakathi. Ngokusebenzisa isikhathi sokurekhoda sokundiza kwamasignali amaza, ibanga ukusuka kuthuluzi kuya endaweni ebonakalayo lingabalwa.
Izilinganiso zamaleveli ezinhlobo ezimbili zabelana ngamafomula afanayo:
D = (C*T)/2
L = H - D
Lapho,
D: Ibanga ukusuka endaweni emaphakathi ukuya ensimbini
C: Isivinini somsindo (ye-ultrasonic) isivinini sokukhanya (ye-radar)
T: Isikhawu sesikhathi ukusuka ekukhiqizweni ukuya ekwamukelweni
L: Izinga elimaphakathi okufanele likalwe
H: Ukuphakama ukusuka phansi komkhumbi kuya ensimbini
Ihluka kusukela kumathuluzi avamile asekelwe ekuthinteni, ukuqedwa kokuthintana ngokomzimba nento, ubuchwepheshe be-ultrasonic kanye ne-radar buhamba phambili ekulawuleni izinga lezinto ezibolayo, ezibonakalayo, noma eziyingozi ezingase zilimaze noma zivale izingxenye ezimanzi ezifana nokuntanta, ama-probe, noma imigqa ye-impulse. Ukufakwa kwenziwa lula njengoba amadivayisi afakwe ngaphandle futhi isidingo sokunakekelwa nesikhathi sokuphumula ngokuvamile sigcinwa sisincane ngenxa yedizayini engahlanyisi. Izimboni ezifana nokucubungula amakhemikhali, ukwelashwa kwamanzi, nokukhiqizwa kokudla zingazuza kakhulu kuzinzwa zezinga lokungaxhunywanwanga ne-radar ngokuguquguquka kwazo nokuthembeka phakathi kwezilawuli zenqubo zoketshezi, uketshezi, i-slurry, neziqinile kuwo wonke amajiyometri ethangi ahlukahlukene.
Ukuqhathanisa phakathi kwe-ultrasonic ne-radar
Imitha yezinga le-Ultrasonic ilula ukufakwa futhi idinga ukusetha okuncane. Uma kuqhathaniswa nemitha yezinga le-radar, i-ultrasonic ngokuvamile ibiza kancane ngakho-ke ikhethwa ezinhlelweni zokusebenza ezinezingqinamba zesabelomali. Kodwa-ke, ukusebenza kwezinsimbi ze-ultrasonic kungaphansi kakhulu emiphumeleni yemvelo yothuli, igwebu, ukuthuthumela komoya kanye nezinga lokushisa elidlulele kanye nomswakama obungamunca noma buphambukise amagagasi omsindo futhi kubangele ukulahleka kwamagagasi.
Ngakolunye uhlangothi, igeji yezinga le-radar yaziwa ngokunemba okuphezulu, ibanga elide kanye nokwethembeka okuqinisekisiwe endaweni yokusebenza enzima. Akulula ukungenwa yizinto ezingaphezulu kwaleyo nkinga yobuchwepheshe be-ultrasonic. Noma kunjalo kusho ukuthi imikhiqizo ye-radar ngokuvamile ibiza kakhulu. I-Dielectric constant kungenye into ebalulekile yokulinganisa i-radar. Izinto eziphansi ze-dielectric zingenza buthaka ukubonakaliswa kwesignali ye-echo okuholela esilinganisweni esingazinzile noma esilahlekile.
Kafushane, lapho umsebenzisi enquma ukusebenzisa isilinganiso sezinga lokungaxhunywana naye, inzwa ye-ultrasonic ingaba ilungele isimo sokusebenza esisesilinganisweni kanye nephrojekthi eqaphela ibhajethi kuyilapho i-radar ifanelekela indawo eyinselele eyengeziwe kanye nokuphishekela ukulinganisa okuphezulu. Kunoma ikuphi, kubalulekile ukuqinisekisa ukuthi izici eziphakathi nendawo nendawo, kanye nesakhiwo sesistimu yenqubo, kulungele ukuqaliswa kwendlela yokulinganisa yokungathintwa efiselekayo.
Amanothi okufaka wamathuluzi angaxhunywanga
- ✦ Indawo yokufaka kufanele ibe kude ngangokunokwenzeka nomthombo womsindo
- ✦ I-gasket yerabha ingasetshenziselwa ukufakwa ngaphansi kwemvelo yokudlidliza

- ✦ Indawo yenzwa kufanele igcine ibanga elithile ngodonga lwesiqukathi ngokuya nge-engeli ephumayo
- ✦ Indawo yokulinganisa kufanele ingabi nezithiyo ezingase zibangele ukuphazamiseka kwesignali njengesitebhisi noma i-crossbeam
- ✦ Ngesilinganiso esimaphakathi esiqinile, indawo yokukhweza kufanele igweme indawo yokuvula okuphakelayo
- ✦ Kungcono kakhulu ukugwema ukuguquguquka okukhulu kwezinga lokushisa endaweni yokufaka insimbi
- ✦ I-sensor probe izoba perpendicular kuya endaweni emaphakathi ukuze kuvikelwe ukusebenza okuhle kakhulu
Shanghai Wangyuanungumkhiqizi wezinsimbi onolwazi eminyakeni engaphezu kwengu-20 ehlinzeka ngezinzwa zeleveli ye-ultrasonic ne-radar kanye nezinye izinhlobo zamathuluzi okulinganisa amazinga. Sicela uzizwe ukhululekile ukusithinta ngemibuzo yakho ngemikhiqizo yokulinganisa izinga lokungaxhunywanwa naye.
