█Nhanganyaya
Uchishandisa iyo ultrasonic sensor seye transmitter uye inogamuchira, iyo transmitter inoburitsa yakaenzana amplitude ultrasonic wave kunzvimbo yakaonekwa uye inogamuchira inogamuchira inoratidzwa ultrasonic wave, kana pasina chinhu chinofamba munzvimbo yakaonekwa, iyo inoratidzwa ultrasonic wave ndeye yakaenzana amplitude. .Kana paine chinhu chinofamba munzvimbo yekuona, iyo inoratidzwa ultrasonic wave amplitude inosiyana uye inochinja nguva dzose, uye dunhu rinogamuchira rinoona shanduko yekuchinja kudzora dunhu kuita, ndiko kuti, kutyaira alarm.
Ultrasonic burglar alarm
█Working musimboti we ultrasonic anti-kuba alarm
Zvinoenderana nechimiro chayo uye nzira dzekuisa dzakakamurwa kuita marudzi maviri: imwe kuisirwa maviri e ultrasonic transducers mudzimba imwechete, kureva, transceiver uye transmitter yakasanganiswa mhando, kushanda kwayo kwakavakirwa paDoppler mhedzisiro yemafungu eruzha, zvakare. inozivikanwa seDoppler type.Kana pasina chinhu chinofamba chinopinda munzvimbo yakaonekwa, mafungu e ultrasonic anoratidzwa akaenzana amplitude.Kana chinhu chinofamba chikapinda munzvimbo yakaonekwa, iyo inoratidzwa ultrasound ndeyekusaenzana amplitude uye inogara ichichinja.Iyo simba remunda kugoverwa kweiyo emitted ultrasound ine imwe nzira, kazhinji kune iyo yakatarisana-yakatarisana nzvimbo mune elliptical simba munda kugovera.
Imwe yacho ndiyo matransducer maviri anoiswa munzvimbo dzakasiyana, kureva, kugamuchira uye kutumira kupatsanurwa mhando, inozivikanwa seinzwi remumunda detector, transmitter yayo uye inogamuchira kazhinji isiri-directional (kureva omnidirectional) transducer kana hafu-nzira mhando transducer.Iyo isiri-directional transducer inogadzira hemispherical simba munda wekugovera maitiro uye semi-directional mhando inoburitsa conical simba munda wekugovera maitiro.
Doppler mhando inoshanda musimboti
█Muenzaniso weiyo ultrasonic inoenderera mberi wave chiratidzo chekufambisa wedunhu.

█Nzvimbo dzekushandiswa kweanodzivirira kuba.
Ultrasonic detectors iyo inogona kuona zvinhu zvinofamba zvine huwandu hwakawanda hwemashandisirwo, semuenzaniso, otomatiki kuvhura gonhi nekuvhara kuona uye kutonga;otomatiki kusimudza kutanga;anti-theft alarm detector, etc. Chimiro chemucherechedzo uyu ndechekuti inogona kutonga kana kune mhuka dzinoshanda dzevanhu kana zvimwe zvinhu zvinofamba munzvimbo yakaonekwa.Iine yakakura kudzora denderedzwa uye yakakwirira kuvimbika.
