Idivayisi yomsindo yokuhlola ezwela kakhulu yokulalela ngaphandle kwezindonga
Isithombe somkhiqizo
Incazelo
Idivayisi ye-Listen Through Walls ene-High Sensitivity Audio Acoustic Microphone ingathola futhi iqophe amasignali omsindo we-analog (izwi lomuntu, izinyathelo, eminye imisindo). Ngenxa yokusetshenziswa kwemishini yokucubungula nokukhulisa i-DSP ekhanyayo enomsindo ophansi, isignali ithathwa yizinzwa ze-stereo ezizimele kwesobunxele nakwesokudla engxenyeni engaphambili, bese ikhishwa ngemva kokususwa yiyunithi yokucubungula yokulawula engxenyeni engemuva, ukuze umshini ukwazi ukuthola imisindo emincane kakhulu.
Uhlelo lungalanda umsindongokusebenzisaukwakha izindonga, ophahleni, phansi, njll. Inzwa yangaphandle ixhunywe ku-amplifier yomsindo enikeza ukulawula ivolumu yokuthinta eziteshini zesobunxele nesokudla, kanye nokuqoshwa kwe-USB flash drive yangaphandle. Ingumholi wohlobo olufanayo lwemikhiqizo ngokunikeza umphumela wokulalela onembile, obucayi futhi ocacile kanye nokurekhoda unyaka nesikhathi. Ingazwakala ezakhiweni ezifana nezindonga, ophahleni kanye naphansi, njengasezindaweni lapho kubanjwa khona abathunjwa.
ItAyikwazi ukusetshenziswa nje kuphela njengemishini yokuqapha okusheshayo yamasosha akhethekile, kodwa futhi neyamaphoyisa ezempi, uphenyo lobugebengu, iminyango yophenyo lobuchwepheshe kanye nokulwa nokuhlolwa kwemikhiqizo edingekayo.
Izici
- Ukucubungula i-algorithm yomsindo enamandla ye-DSP eyakhelwe ngaphakathi, ukuqinisekisa ikhwalithi yomsindo engcono kakhulu yokuqapha.
- Inzwa yomsindo yokuhlukanisa yochwepheshe eyenziwe ngokwezifiso, ukudlidliza kokudlulisa inzwa yokushaqeka ngokusebenzisa i-amplifier yomsindo ophansi kakhulu + ukucubungula kwe-DSP, ngisho nesignali yomsindo ebuthakathaka kakhulu nayo ingazwakala.
- Ngezinzwa zomsindo zobungcweti, isiteshi 1 noma isiteshi 2, noma kokubili ukulalela.
- Ngemva kokukhishwa kokucubungula i-DSP, iziteshi ezimbili zingaqoshwa ngasikhathi sinye.
- Imodi yokuqapha: i-headset enezintambo, i-headset ye-Bluetooth engenantambo, ukuqopha.
- Ukusebenza kokuthinta nokudlidliza kobungcweti nokwenziwe ngokwezifiso.

Isingeniso Senkampani
Ngo-2008, iBeijing Hewei Yongtai Technology Co., LTD yasungulwa eBeijing. Igxile ekuthuthukisweni nasekusetshenzisweni kwemishini ekhethekile yokuphepha, ikakhulukazi ekhonza umthetho wokuphepha komphakathi, amaphoyisa ahlomile, amasosha, amasiko kanye neminye iminyango yokuphepha kazwelonke.
Ngo-2010, iJiangsu Hewei Police Equipment Manufacturing Co., LTD yasungulwa eGuannan. Ihlanganisa indawo engamamitha-skwele angu-9000 esakhiwo seworkshop kanye nehhovisi, ihlose ukwakha isisekelo socwaningo nentuthuko yemishini yokuphepha ekhethekile esezingeni eliphezulu eShayina.
Ngo-2015, i-Rese yamaphoyisa ezempiaIsikhungo sokwakha kanye nokuthuthukiswa sasungulwa eShenzhen. Sigxile ekuthuthukisweni kwemishini yokuphepha ekhethekile, sakha izinhlobo ezingaphezu kuka-200 zemishini yokuphepha yobungcweti.
Imibukiso Yaphesheya Kwezwe
Izitifiketi
I-Beijing Heweiyongtai Sci & Tech Co., Ltd. ingumhlinzeki ohamba phambili we-EOD kanye ne-Security Solutions. Abasebenzi bethu bonke bangochwepheshe bezobuchwepheshe nabaphathi abafanelekile ukukunikeza isevisi eyanelisayo.
Yonke imikhiqizo inemibiko yokuhlola yezinga lobuchwepheshe likazwelonke kanye nezitifiketi zokugunyazwa, ngakho-ke sicela uqiniseke ukuthi uya-oda imikhiqizo yethu.
Ukulawulwa kwekhwalithi okuqinile ukuqinisekisa ukuthi umkhiqizo uhlala isikhathi eside futhi opharetha usebenza ngokuphepha.
Ngineminyaka engaphezu kwengu-10 yesipiliyoni embonini ye-EOD, imishini yokulwa nobuphekula, idivayisi yobunhloli, njll.
Sikhonze amakhasimende angaphezu kwamazwe angu-60 emhlabeni jikelele ngobungcweti.
