Intshayelelo kwi-Ultrasonic Sensors
Iinzwa ze-Ultrasonic zizivamvo eziphuhliswe ngokusebenzisa iimpawu ze-ultrasound.Iinzwa ze-Ultrasonic zisebenzisa umphumo we-piezoelectric we-piezoelectric ceramics.Xa isignali yombane isetyenziswe kwipleyiti ye-ceramic ye-piezoelectric, iya kuguqula, ibangele ukuba inzwa ishukume kwaye ikhuphe amaza e-ultrasonic.Xa i-ultrasound ibetha umqobo, ibonakalisa umva kwaye isebenze kwi-piezoelectric ceramic plate ngokusebenzisa inzwa.Ngokusekelwe kwi-inverse piezoelectric effect, i-sensor ye-ultrasound ivelisa imveliso yombane.Ngokusebenzisa umgaqo wesantya sokusasazwa rhoqo kwamaza e-ultrasonic kwindawo efanayo, umgama phakathi kwemiqobo unokumiselwa ngokusekelwe kwixesha eliphakathi kokudlulisa kunye nokufumana iimpawu.Amaza e-Ultrasonic aya kuvelisa i-echoes ephawulekayo yokubonakalisa xa edibana nokungcola okanye i-interfaces, kunye nemiphumo ye-Doppler xa bedibana nezinto ezihambayo.Ke ngoko, izinzwa ze-ultrasonic zisetyenziswa ngokubanzi kumashishini, ukusetyenziswa koluntu, ukhuselo lwelizwe, i-biomedicine, kunye namanye amacandelo.
Usetyenziso
1. I-radar ye-Automotive anti-collision radar, i-ultrasonic rangeing system, i-ultrasonic proximity switch;
2. Izixhobo zolawulo olukude lwezixhobo zendlu, iithoyi, kunye nezinye izixhobo zombane;
3. Ukukhutshwa kwe-Ultrasonic kunye nezixhobo zokwamkela izixhobo zokulwa nobusela kunye nokuthintela iintlekele.
4.Isetyenziselwa ukugxotha iingcongconi, izinambuzane, izilwanyana, njl.
Izaziso
1. I-ultrasonic emitter ikhupha i-ultrasonic beam kwi-angle ye-60 degree ngaphandle, ngoko akufanele kubekho imiqobo phakathi kweprobe kunye nento elinganisiweyo.
2. Imodyuli ye-ultrasonic ilinganisa umgama othe nkqo phakathi kwento elinganisiweyo kunye neprobe, kwaye i-probe kufuneka igcinwe ijongene nento elinganisiweyo ngexesha lokulinganisa.
3. Umlinganiselo we-Ultrasonic uphenjelelwa sisantya somoya esisingqongileyo, ubushushu, njl.
Imiba enokwenzeka
1. Ngenxa yempembelelo yokungalingani kwento elinganisiweyo, i-angle yokubonakalisa i-angle, isantya somoya wendalo esingqongileyo kunye neqondo lokushisa, kunye nezibonakaliso ezininzi, amaza e-ultrasonic anokunyusa iimpazamo zedatha yokulinganisa.
2. Ngenxa yeempawu zendalo ze-ultrasound ekulinganiseni iindawo ezingaboniyo, ukuba indawo yokulinganisa iyatshintsha kwaye idatha efunyenweyo ihlala ingatshintshi ngexesha lokulinganisa uluhlu olusondeleyo, lubonisa ukuba indawo eyimfama yokulinganisa ingenisiwe.
3. Ukuba akukho datha yokulinganisa ibuyiswayo xa imodyuli ilinganisa izinto ezikude, ingaba ngaphandle koluhlu lokulinganisa okanye i-angle yokulinganisa ingachanekanga.I-angle yokulinganisa inokulungelelaniswa ngokufanelekileyo.
