Izinzwa ze-M-254 Infrared — I-Microwave vs Ukutholwa Okusebenzayo Kwezindlela Zokungena Eminyango Ezizenzakalelayo

Umnyango Ongavuleki Kudokotela kanye Nomnyango Ovulekele Wonke Amaloli Adlulayo

Ngithole izingcingo ezimbili ngesonto elifanayo ezivela kumakhasimende e-Ningbo Yufan Beifan, futhi zibonisa kahle izindlela ezimbili zokwehluleka engizibona kaningi lapho izinhlelo zokuthola iminyango ezizenzakalelayo zingachazwanga kahle.

Umuntu wokuqala owayeshayela ucingo kwakuyisibhedlela eNingbo. Udokotela wayefake isikhalazo esisemthethweni sokuthi iminyango eshelelayo ezenzakalelayo esangweni lomnyango wezimo eziphuthumayo yehluleka ukuvuleka ngokuphindaphindiwe njengoba esondela ecindezela i-gurney. Umphathi wokulungisa wayeseshintshe i-sensor yokunyakaza kabili kanye nebhodi lokulawula umnyango kanye, ngaphandle kokuthuthukiswa. Lapho ngivakashela indawo, ngathola inkinga ngokushesha: umnyango wawucacisiwe nge-sensor yokunyakaza kwe-microwave, kanti udokotela wayesondela ngesivinini sokuhamba kancane ngenkathi ebambe i-gurney iqine - empeleni emkhawulweni wejubane ongaphansi lapho izinzwa eziningi ze-microwave zibekwe khona ukuqala. I-sensor yayisebenza njengoba yayiklanyelwe; yayingaklanyelwanga uhlelo lokusebenza.

Ucingo lwesibili lwaluvela enkampanini yezokuthutha eHangzhou. Umnyango wabo ozenzakalelayo wedoko lokulayisha impahla wawuvuleka njalo usuku lonke - njalo lapho i-forklift idlula emnyango osendleleni eseduze, inzwa ye-microwave yabona ukunyakaza futhi yavusa umnyango. Lokhu kwakubangela ukulahlekelwa amandla okuvela emoyeni olawulwa yisimo sezulu ophuma ngomnyango ovuleka njalo, futhi kwakudala ingozi yokuphepha ngoba abasebenzi base beqale ukungawunaki ukuvulwa komnyango njengesignali. Inzwa ye-microwave yayisebenza kahle kulokho eyayiklanyelwe ukukwenza; yayimane ifakwe endaweni lapho ukuzwela kwayo kwakudingeka kugcinwe khona endaweni encane yokuthola.

Lezi zimo ezimbili ziyizithombe ezibukwayo zephutha elifanayo eliyisisekelo lokucacisa: ukukhetha ubuchwepheshe bokuthola obusekelwe ekujwayelaneni noma ezindleleni kunokuba kuhlaziywe ngokuhlelekile kwezidingo zangempela zohlelo lokusebenza. Endabeni yesibhedlela, ikhambi kwakuwukufaka esikhundleni senzwa ye-microwave ngenzwa yekhethini le-infrared esebenzayo ye-M-254 ethola ukuba khona kunokunyakaza, iqinisekise ukuthi umnyango uyavuleka kungakhathaliseki ukuthi udokotela usondela kancane kangakanani. Endabeni ye-logistics, ikhambi kwakuwukufaka ikhethini le-infrared le-M-254 njengenzwa yokuphepha kokuba khona (ukuvimbela umnyango ukuthi uvale ku-forklift esesemnyango) ngenkathi kugcinwa inzwa ye-microwave ukuze kusebenze ukunyakaza ngemingcele yokuthola elungisiwe kahle.

Indlela Ubuchwepheshe Bokuthola Iminyango Okuzenzakalelayo Obusebenza Ngayo Ngempela

Ngaphambi kokuxoxa ngezinqubo zokukhetha, kufanelekile ukuqonda izimiso ezibonakalayo ezisekela ubuchwepheshe bokuthola ngabunye, ngoba lokhu kuqonda kubalulekile ekwenzeni izinqumo ezinolwazi. Ukudideka emakethe kuqhutshekiswa kancane ulimi lokumaketha olungacacile oluchaza ubuchwepheshe obuhlukene ngamagama azwakala afana kodwa achaza amakhono ahlukene ngokuyisisekelo.

Ukutholwa Kwekhethini Le-Infrared Elisebenzayo: Ukuchazwa Kobuchwepheshe Be-M-254

Igama le-M-254 libhekisela ekilasini lezinzwa zokubona ubukhona ze-infrared ezisebenzayo ezisebenzisa ikhethini lemisebe ye-infrared eguquliwe ukudala indawo yokuthola ngaphesheya komnyango. Inzwa inamayunithi amabili: i-emitter eveza imisebe eminingi ye-infrared ngaphesheya komnyango, kanye ne-receiver ethola imisebe. Uma yonke imisebe ingavinjelwe, umphumela wenzwa awusebenzi (ukulawula umnyango kuhumusha lokhu njengokuthi "akukho ukuba khona emnyango"). Uma imishayo eyodwa noma ngaphezulu iphazamiseka, umphumela wenzwa ushintsha isimo (ukulawula umnyango kuhumusha lokhu njengokuthi "ukuba khona kutholiwe, umnyango kufanele uvuleke noma uhlale uvulekile").

Isici esiyinhloko sokutholwa kwe-infrared esebenzayo — futhi esikuhlukanisa kakhulu ne-microwave — ukuthi itholaukuba khona, hhayiukunyakazaUmuntu omi anganyakazi ngokuphelele endaweni yokuthola uzotholakala ngokwethembeka njengomuntu odlula ngesivinini. Lokhu kungenxa yokuthi inzwa ilinganisa ukungabikho noma ukuba khona kokukhanya kwe-infrared, hhayi noma yiluphi ushintsho endaweni ezungezile.Ngenxa yokuthi ukutholwa kwesihenqo se-infrared esisebenzayo kudinga indlela yokukhanya engaphazanyiswa phakathi kwe-emitter ne-receiver, kuyazwela ezimweni ezingavimba noma zisakaze ukukhanya — imvula enkulu, ukukhanya kwelanga okuqondile ku-receiver lens, ukunqwabelana kweqhwa kulensi yenzwa, noma izindawo ezinothuli kakhulu..

Izinzwa ze-M-254 kuhlu lomkhiqizo we-Yufan Beifan zisebenzisa umklamo wezinsimbi eziningi ngokuvamile onezinsimbi ezingu-8, 12, noma ezingu-24 kuye ngohlobo, kanye nesikhala sezinsimbi esingu-20mm kuya ku-50mm. Inani lezinsimbi kanye nesikhala sazo linquma isinqumo sokuthola — inzwa enezinsimbi ezingu-24 esikhaleni esingu-20mm izobona ingane encane noma isilwane esifuywayo inzwa enezinsimbi ezingu-8 esikhaleni esingu-60mm engasivumela ukuba sidlule singabonwanga. Lena ipharamitha ebalulekile yokucacisa yezinhlelo zokusebenza ezindaweni ezinabantu abaningi abahamba ngezinyawo okuhlanganisa nezingane noma izilwane.

Ukutholwa Kwe-Microwave: Izimiso Zokusebenzisa Ama-Doppler Ezisetshenziswa Eminyango Ezenzakalelayo

Izinzwa zokuthola ama-microwave zeminyango ezenzakalelayo zisebenza ngesimiso se-Doppler: inzwa ikhipha isignali ye-microwave eqhubekayo ngemvamisa ehleliwe (ngokuvamile engu-24.125 GHz yezinzwa zeminyango ye-K-band, esebhendini yomsakazo ye-ISM egcinelwe izinhlelo zokusebenza zezimboni, zesayensi, kanye nezokwelapha), futhi ithola ukushintsha kwemvamisa esignalini eboniswayo okubangelwa izinto ezihambayo.

Uma inzwa ye-microwave ifakiwe ngaphezu kohlaka lomnyango, ikhipha indawo yokuthola efana nekhoni edlula ngaphandle kwenzwa. Ama-microwave aveza izinto ezimile (izindonga, phansi, izimoto ezipakiwe) ngemvamisa efanayo naleyo ezikhishwa ngayo, engakhiphi ukushintsha kwe-Doppler. Uma into ehambayo ingena endaweni yokuthola, ama-microwave abonakalayo abuya ngemvamisa ehlukile kancane - ephakeme uma into isondela kunzwa, yehla uma ihamba. Inzwa icubungula lokhu kushintsha kwemvamisa ukuze inqume ukuthi ukunyakaza kuyenzeka futhi ithumela isignali yokwenza kusebenze kumlawuli womnyango.

Ipharamitha ebalulekile yokucaciswa kwezinzwa ze-microwave yi-ijubane elincane elitholakalayo— into ehamba kancane kakhulu ezoqala umcimbi wokutholwa. Izinzwa eziningi zeminyango ye-microwave yezentengiselwano zisethelwe embonini ukuthi ziqale izinto ezihamba ngesivinini esingu-0.5 m/s noma ngokushesha. Lokhu kufaneleka kubantu abahamba ngezinyawo abavamile kodwa kudala imodi yokwehluleka esiyibonile ecaleni lesibhedlela: udokotela osondela ngesivinini sokuhamba kancane esingu-0.3–0.4 m/s ngenkathi elawula ngokucophelela i-gurney ngeke aqale inzwa.

Ngenxa yokuthi izinzwa ze-microwave zibona ijubane lokunyakaza kunokuba zibe khona, azikwazi ukuhlukanisa phakathi komuntu ohamba ngezinyawo osondela emnyango nemoto edlula emnyango emgwaqweni oseduze — noma phakathi komuntu ohamba ngezinyawo nenqola yokuthenga esunduzwa emnyango eceleni kwendlela.Lokhu kungaqondakali kuyimbangela eyinhloko yezinkinga ezibangelwa yizinto ezingamanga esizibonayo ezindaweni zokuthutha kanye nezindawo zokuthengisa lapho kuhlangana khona abantu abahamba ngezinyawo kanye nezimoto.

Ukutholwa Kokunyakaza Okusebenzayo Kwe-Infrared: Indlela Ehlanganisiwe

Isigaba sesithathu okufanele siqondwe yi-active infraredukunyakazaukutholwa — izinzwa ezisebenzisa ubuchwepheshe be-infrared (ngokuvamile i-PIR ye-infrared engasebenzisi noma i-IR esebenzayo eguquliwe) ukuthola ukunyakaza kunokuba khona. Lezi zinzwa zisebenza ngokuthola izinguquko kusiginesha yokushisa ye-infrared endaweni yokutholwa — umzimba ofudumele (umuntu noma isilwane) ohamba ngaphesheya kwensimu yokubuka yenzwa udala iphethini yokushisa eshintshayo inzwa eyichaza njengokunyakaza.

Izinzwa zokunyakaza ze-PIR zisetshenziswa kabanzi ezinhlelweni zokulawula ukukhanya kwangaphandle kanye nezokuphepha kwezakhiwo, kodwa ngokuvamile azifaneleki ukusetshenziswa kweminyango ezenzakalelayo ngenxa yesikhathi sazo sokuphendula esisheshayo (ngokuvamile imizuzwana engu-0.5-2), ukuthambekela kwazo ekubangeleni okungamanga okuvela ekushintsheni kwezinga lokushisa elizungezile, kanye nekhono lazo elilinganiselwe lokuhlukanisa ukunyakaza komuntu nokunyakaza kwesilwane ezindaweni zangaphandle. Angizincomi izinzwa zokunyakaza ze-PIR zokusebenzisa umnyango ozenzakalelayo kunoma yiluphi uhlelo lokusebenza lwezentengiselwano.

Qinisekisa uhlobo lokukhipha ngaphambi koku-oda — ukucushwa kokukhipha okungahambelani kuyiphutha elivamile lokufaka elingabangela ukusebenza ngezikhathi ezithile noma ukwehluleka okuphelele kwesistimu.
5. Uhlelo lokufinyelela ekulungiseni:Izinzwa zekhethini le-infrared zidinga ukuhlanzwa kwelensi njalo kanye nokuqinisekiswa kokulungiswa kwemisebe, ikakhulukazi ezindaweni ezinothuli noma zangaphandle. Cacisa imodeli yesensa evumela ukufinyelela kwelensi ngaphandle kokususa yonke inhlangano yesensa ohlakeni lomnyango. Izinzwa ezidinga ukuhlukaniswa okuphelele kokuhlanza ilensi zandisa isikhathi sokulungisa ngesilinganiso esingu-3-5.
6. Cabanga ngokufakwa kwe-hybrid ezindaweni ezidinga kakhulu:Uma uhlelo lwakho lokusebenza lunanoma yiziphi izici ezilandelayo — ukusebenza komnyango ngesivinini esikhulu, ukuchayeka ngaphandle, ukuhamba kwabantu abahamba ngezinyawo kanye nezimoto ezixubile, noma amazinga okushisa aphezulu — hlela uhlelo lokuthola oluhlanganisiwe kusukela ekuqaleni kunokwengeza inzwa yesibili njenge-retrofit ngemva kokuba inzwa eyinhloko ingabonakali inganele.

Kungani Ukukhetha Ubuchwepheshe Bokuthola Kuyisinqumo Esichazayo Esinethonya Kakhulu Kuhlelo Lomnyango Ozenzakalelayo

Bengilokhu ngiphatha amaphrojekthi eminyango ezenzakalelayo eYufan Beifan iminyaka eminingi, futhi ngingakutshela ngokuhlangenwe nakho kwami ​​ukuthi imininingwane yobuchwepheshe bokuthola iyisinqumo esisodwa esinomthelela kakhulu ohlelweni lonke lweminyango ezenzakalelayo — esinomthelela kakhulu kunencazelo yomqhubi weminyango, uhlelo lokushayela, noma ngisho nokwakhiwa kwephaneli yeminyango. Umnyango ozenzakalelayo wekhwalithi ephezulu onesistimu yokuthola engacacisiwe kahle uzoletha ulwazi lomsebenzisi olubi njalo. Umnyango oshelelayo ozenzakalelayo ojwayelekile onobuchwepheshe bokuthola obufanele uzosebenza ngokuthembekile iminyaka eminingi.

Isizathu silula: uhlelo lokuthola luyindlela yokuxhumana phakathi komsebenzisi nomnyango. Konke ukuxhumana umuntu anakho nomnyango ozenzakalelayo kuqala futhi kuphele ngohlelo lokuthola. Uma umnyango ungavuli lapho esondela, ulahlekelwa ukwethemba uhlelo. Uma umnyango uvula lapho engafuni, uyacasuka noma uyacasuka.Ngenxa yokuthi ubuchwepheshe bokuthola bunquma ngqo ukuthi lokhu kusebenzisana kuhle noma kubi, ukucacisa ubuchwepheshe bokuthola obufanele akuyona imininingwane yobunjiniyela - kuyisisekelo sokwaneliseka komsebenzisi ngohlelo lonke lomnyango oluzenzakalelayo..

Uhla lwemikhiqizo kaYufan Beifan luhlanganisa ubuchwepheshe obuphelele bokuthola iminyango ngokuzenzakalelayo — izinzwa zekhethini ezisebenzayo ze-M-254 ezilungiselelweni eziningi ze-beam, izinzwa zokunyakaza kwe-microwave ezinezindawo zokuthola ezilungisekayo, kanye nama-hybrid dual-sensor kit ezinhlelo zokusebenza zezimboni nezokunakekelwa kwempilo ezidingayo. Uma ucacisa uhlelo lomnyango oluzenzakalelayo futhi udinga isiqondiso ngobuchwepheshe bokuthola obufanele besicelo sakho, ithimba lethu lokuthengisa lobuchwepheshe liyatholakala ukukunikeza izincomo eziqondene nephrojekthi ethile.
