Nhanganyaya kune Ultrasonic Sensors
Ultrasonic sensors ma sensor akagadzirwa achishandisa maitiro e ultrasound.Ultrasonic sensors inoshandisa piezoelectric mhedzisiro yepiezoelectric ceramics.Kana chiratidzo chemagetsi chikaiswa kune piezoelectric ceramic plate, inokonzeresa, zvichiita kuti sensor idengenyeke uye inoburitsa masaisai e ultrasonic.Kana Ultrasound ikarova chipingamupinyi, inoratidzira kumashure uye inobata pane piezoelectric ceramic ndiro kuburikidza ne sensor.Kubva pane inverse piezoelectric effect, iyo ultrasound sensor inogadzira chiratidzo chemagetsi kubuda.Nekushandisa iyo musimboti wekuramba uchiparadzira kumhanya kwemafungu e ultrasonic mune imwechete svikiro, chinhambwe chiri pakati pezvipingamupinyi chinogona kutariswa zvichibva pamusiyano wenguva pakati pekutumira nekugamuchira masaini.Ultrasonic masaisai anozoburitsa akakosha echiratidziro paanosangana netsvina kana nzvimbo, uye Doppler mhedzisiro pavanosangana nezvinhu zvinofamba.Naizvozvo, ma ultrasonic sensors anoshandiswa zvakanyanya mumaindasitiri, kushandiswa kwevanhu, kudzivirira kwenyika, biomedicine, uye mamwe minda.
Applications
1. Automotive anti-collision radar, ultrasonic rangeng system, ultrasonic proximity switch;
2. Zvishandiso zvechiremote zvemidziyo yemumba, matoyi, uye zvimwe midziyo yemagetsi;
3. Ultrasonic emission uye midziyo yekugamuchira yekurwisa-kuba uye midziyo yekudzivirira njodzi.
4.Inoshandiswa kudzinga umhutu, zvipembenene, mhuka, nezvimwe.
Zviziviso
1. Iyo ultrasonic emitter inoburitsa ultrasonic beam pane 60 degree angle kunze, saka hapafanirwe kuve nezvimwe zvipingamupinyi pakati peprobe uye chinhu chakayerwa.
2. The ultrasonic module inoyera kureba pakati pechinhu chakayerwa neprobe, uye probe inofanira kuchengetwa yakatarisana nechinhu chakayerwa panguva yekuyera.
3. Ultrasonic kuyerwa kunokonzerwa nekumhanya kwemhepo yemhepo, tembiricha, nezvimwe.
Zvinogona kuitika
1. Nekuda kwesimba rekusaenzana kwechinhu chakayerwa, angle yekuratidzira, kumhanya kwemhepo yemhepo uye tembiricha, uye kuratidzwa kwakawanda, masaisai e ultrasonic anogona kuwedzera kuyerwa kwedata.
2. Pamusana pehutano hwemasikirwo e ultrasound pakuyera mapofu mapofu, kana nzvimbo yekuyera ichichinja uye data yakagamuchirwa inoramba isingachinji panguva yekuyera kwepedyo, inoratidza kuti kuyerwa kwemapofu kwakapinda.
3. Kana pasina chiyero chekuyera chinodzoserwa kana module ichiyera zvinhu zviri kure, inogona kunge iri kunze kwekuyerwa kwechiyero kana kuyerwa kwekona kungave kusina kunaka.Iko kuyerwa kwekona kunogona kugadziriswa zvakakodzera.
