Ucango Olungavulelwanga Ugqirha Noluvulekele Zonke Iilori Ezidlulayo
Ndifumene iifowuni ezimbini kwiveki enye ezivela kubathengi beNingbo Yufan Beifan, kwaye zibonisa kakuhle iindlela ezimbini zokungaphumeleli endizibona rhoqo xa iinkqubo zokuchonga iingcango ngokuzenzekelayo zingachazwanga ngokuchanekileyo.
Umntu wokuqala ofowunelayo yayisibhedlele eNingbo. Ugqirha wayefake isikhalazo esisemthethweni sokuba iingcango ezityibilikayo ezizenzekelayo emnyango wecandelo likaxakeka azivulekanga ngokuphindaphindiweyo njengoko wayesondela etyhala i-gurney. Umphathi wolondolozo wayetshintshe i-motion sensor kabini kunye nebhodi yokulawula ucango kanye, kungekho phuculo. Xa ndandityelela indawo, ndafumanisa ingxaki ngoko nangoko: umnyango wawuchazwe nge-microwave motion sensor, kwaye ugqirha wayesondela ngesantya esicothayo ngelixa ebambe i-gurney ngokuqinileyo - ngokuyintloko kumda wesantya ongaphantsi apho uninzi lwee-microwave sensors zimiselwe ukuqala khona. I-sensor yayisebenza kanye njengoko yayilungiselelwe; yayingalungiselelwanga ukusetyenziswa.
Umnxeba wesibini wawuvela kwinkampani yezothutho eHangzhou. Ucango lwabo oluzenzekelayo lwedokhi yokulayisha impahla lwaluvuleka rhoqo imini yonke - ngalo lonke ixesha i-forklift idlula emnyango kwindlela esecaleni, i-microwave sensor yayibona intshukumo yaza yaqalisa ucango. Oku kwakubangela ukulahleka kwamandla ngenxa yomoya olawulwa yimozulu ophuma ngocango oluhlala luvuleka, kwaye kwakudala ingozi yokhuseleko kuba abasebenzi babeqale ukungawunaki ucango njengomqondiso. I-microwave sensor yayisebenza ngokuchanekileyo kwinto eyayiyilelwe ukuyenza; yayifakwe nje kwindawo apho uvakalelo lwayo lwalufuneka lugcinwe kwindawo encinci yokubhaqwa.
Ezi meko zimbini ziyimifanekiso esipilini yempazamo efanayo esisiseko yenkcazo: ukukhetha iteknoloji yokufumanisa esekelwe kulwazi okanye kwixabiso endaweni yohlalutyo olucwangcisiweyo lweemfuno zokwenyani zesicelo. Kwimeko yesibhedlele, isisombululo yayikukutshintsha isensa ye-microwave ngesensa ye-infrared curtain esebenzayo ye-M-254 ebona ubukho endaweni yentshukumo, ukuqinisekisa ukuba ucango luvuleka nokuba ugqirha usondela kancinci kangakanani na. Kwimeko ye-logistics, isisombululo yayikukufaka isensa ye-infrared ye-M-254 njengesensa yokhuseleko lobukho (ukuthintela ucango ukuba luvaleke kwi-forklift esesemnyango) ngelixa kugcinwa isensa ye-microwave ukuze isebenze intshukumo enemida yokufumanisa elungisiweyo ngokufanelekileyo.
Indlela iiTekhnoloji zokuHlola iiNgcango eziZenzekelayo eziSebenza ngayo
Ngaphambi kokuba sixoxe ngemigangatho yokukhetha, kubalulekile ukuqonda imigaqo ebonakalayo esekwe kwitekhnoloji nganye yokuchonga, kuba olu lwazi lubalulekile ekwenzeni izigqibo ezichanekileyo. Ukudideka kwimarike kuqhubeka ngokuyinxenye lulwimi lokuthengisa olungacacanga oluchaza itekhnoloji ezahlukeneyo ngamagama avakala efana kodwa achaza ubuchule obahlukeneyo ngokusisiseko.
Ukufunyanwa kweKheteni ye-Infrared esebenzayo: Inkcazo yeTekhnoloji ye-M-254
Igama le-M-254 libhekisa kudidi lwee-sensors ezisebenzayo zokubona ubukho be-infrared ezisebenzisa ikhethini ye-infrared beams eguquliweyo ukwenza indawo yokufumanisa ngaphaya komda womnyango. I-sensor ineeyunithi ezimbini: i-emitter eveza i-infrared beams ezininzi ngaphesheya komnyango, kunye ne-receiver ebona i-beams. Xa yonke i-beams ingaphazanyiswa, i-sensor output ayisebenzi (ulawulo lomnyango lutolika oku ngokuthi "akukho bukhona emnyango"). Xa i-beam enye okanye ezingaphezulu ziphazamisekile, i-sensor output itshintsha imeko (ulawulo lomnyango lutolika oku ngokuthi "ubukho bufunyenwe, ucango kufuneka luvuleke okanye luhlale luvuliwe").
Uphawu oluphambili lokufumanisa i-infrared esebenzayo — kwaye oluyahlula kakhulu kwi-microwave — kukuba iyayibonaubukho, hayiintshukumoUmntu omi bhuxe kwindawo yokuchonga uya kubhaqwa ngokuthembekileyo njengomntu odlula ngesantya. Oku kungenxa yokuba inzwa ilinganisa ukungabikho okanye ubukho bomsebe we-infrared, hayi naluphi na utshintsho kwindalo esingqongileyo.Ngenxa yokuba ukufunyanwa kwekhethini elisebenzayo le-infrared kufuna indlela engenakuphazamiseka phakathi kwe-emitter kunye ne-receiver, inovelwano kwiimeko ezinokuthintela okanye zisasaze i-beam - imvula enkulu, ukukhanya kwelanga ngqo kwi-receiver lens, ukuqokelelwa kwekhephu kwi-sensor lens, okanye iindawo ezinothuli kakhulu..
Iisensa ze-M-254 kuluhlu lweemveliso zeYufan Beifan zisebenzisa uyilo lwemiqadi emininzi enemiqadi eyi-8, 12, okanye 24 ngokuxhomekeke kwimodeli, kunye nesithuba semiqadi esiyi-20mm ukuya kwi-50mm. Inani lemiqadi kunye nesithuba sayo simisela isisombululo sokufumanisa - isensa enemiqadi engama-24 kwisithuba se-20mm iya kubona umntwana omncinci okanye isilwanyana sasekhaya esiza kuvumela isensa enemiqadi eyi-8 kwisithuba se-60mm ukuba sidlule singabonwanga. Le yiparameter ebalulekileyo yeenkcukacha zokusetyenziswa kwiindawo ezinabantu abaninzi abahamba ngeenyawo kuquka abantwana okanye izilwanyana.
Ukufunyanwa kweMicrowave: Imigaqo yeDoppler esetyenziswa kwiingcango ezizenzekelayo
Izinzwa zokubona i-microwave zeengcango ezizenzekelayo zisebenza ngokomgaqo weDoppler: inzwa ikhupha isignali ye-microwave eqhubekayo kwi-frequency emiselweyo (ngesiqhelo i-24.125 GHz yezinzwa zomnyango we-K-band, ezikwibhendi yerediyo ye-ISM egcinelwe ukusetyenziswa kwemizi-mveliso, isayensi, kunye nezonyango), kwaye ibona utshintsho lwe-frequency kwisignali eboniswayo ebangelwa zizinto ezihambayo.
Xa i-sensor ye-microwave ifakelwe ngaphezulu kwesakhelo somnyango, ikhupha indawo yokubona efana nekhowuni ephuma kwi-sensor. Ii-microwave zibonisa izinto ezimileyo (iindonga, imigangatho, izithuthi ezipakishiweyo) ngesantya esifanayo nezikhutshwayo, nto leyo engenzi ukuba i-Doppler shift. Xa into ehambayo ingena kwindawo yokubona, ii-microwave ezibonisiweyo zibuya ngesantya esahlukileyo kancinci - phezulu ukuba into isondela kwi-sensor, phantsi ukuba iyahamba. I-sensor icubungula olu tshintsho lwesantya ukuze ibone ukuba intshukumo iyenzeka kwaye ithumela isignali yokuvula kumlawuli womnyango.
Ipharamitha ebalulekileyo yeenkcukacha zee-sensors ze-microwave yiisantya esincinci esibonakalayo— eyona nto ihamba kancinci eya kubangela isiganeko sokubhaqwa. Uninzi lwee-sensors zomnyango we-microwave zorhwebo zimiselwe ukuba ziqalise kwizinto ezihamba nge-0.5 m/s okanye ngokukhawuleza. Oku kufanelekile kubantu abahamba ngeenyawo abaqhelekileyo kodwa kudala imo yokusilela esiyibonileyo kwimeko yesibhedlele: ugqirha osondela ngesantya esicothayo se-0.3–0.4 m/s ngelixa elawula ngononophelo i-gurney akayi kubangela i-sensor.
Ngenxa yokuba izinzwa ze-microwave zibona isantya sokuhamba endaweni yokuba zibone ukuba zikhona, azikwazi ukwahlula phakathi komntu ohamba ngeenyawo osondela emnyango kunye nesithuthi esidlula emnyango kwindlela esecaleni - okanye phakathi komntu ohamba ngeenyawo kunye nenqwelo yokuthenga etyhalelwa ngaphaya komnyango ecaleni kwendlela.Oku kungacaci kakuhle yeyona nto iphambili kwiingxaki ezibangelwa bubuxoki esizibonayo kwiindawo zothutho kunye neendawo zokuthengisa apho abantu abahamba ngeenyawo kunye nabahamba ngezithuthi zidityaniswe khona.
Ukufunyanwa kweNtshukumo ye-Infrared esebenzayo: Indlela yeHybrid
Udidi lwesithathu olufanele ukuqondwa yi-active infraredintshukumoukufumanisa — izinzwa ezisebenzisa ubuchwepheshe be-infrared (ngesiqhelo i-PIR ye-infrared engashukumiyo okanye i-IR esebenzayo eguquliweyo) ukufumanisa intshukumo endaweni yokubakho. Ezi zinzwa zisebenza ngokufumanisa utshintsho kwisiginitsha yobushushu be-infrared kwindawo yokufumanisa — umzimba ofudumeleyo (umntu okanye isilwanyana) ohambahambayo kwintsimi yokujonga yesinzwa udala ipateni yobushushu etshintshayo ethi isinzwa siyitolike njengentshukumo.
Izinzwa zokuhamba ze-PIR zisetyenziswa kakhulu kwiinkqubo zolawulo lokukhanya kwangaphandle kunye nokhuseleko lwezakhiwo, kodwa ngokubanzi azifanelekanga ukusetyenziswa kwiingcango ezizenzekelayo ngenxa yexesha lazo lokuphendula elicothayo (ngesiqhelo imizuzwana eyi-0.5–2), ukuthambekela kwazo kwizizathu ezingezizo ezivela kutshintsho lobushushu bemozulu, kunye nokukwazi kwazo ukwahlula intshukumo yomntu kwintshukumo yesilwanyana kwiindawo zangaphandle. Andicebisi izinzwa zokuhamba ze-PIR ukuze kusebenze ingcango ezizenzekelayo kuyo nayiphi na inkqubo yorhwebo.

I-Selection Matrix: Ukuqondanisa iTekhnoloji yokuFumanisa neSicelo
Ngokusekelwe kuthelekiso olungentla kunye namava ethu okuxhasa amakhulu ofakelo lweengcango ezizenzekelayo zeYufan Beifan kwiindawo zorhwebo, zoshishino, kunye neendawo zamaziko, nantsi imatriki yokukhetha esebenzayo edwelisa iintlobo ezithile zezicelo kwiiteknoloji zokuchonga eziphambili nezesibini ezicetyiswayo.
Isicelo Udidi 1: Izakhiwo zoRhwebo kunye neeOfisi
Kwiingcango ezityibilikayo ezizenzekelayo ezithengiswayo, kwiindawo zokuthenga ezinkulu, kwiindawo zokungena kwizakhiwo zeeofisi, nakwiindawo zokungena zeehotele — ezona zixhobo ziqhelekileyo zokungena kweengcango ezizenzekelayo zorhwebo — i-M-254 active infrared curtain sensor kufuneka ibe yiteknoloji ephambili yokubona. Izizathu ziyamangalisa: ezi ndawo zinezithuthi ezininzi zabahambi ngeenyawo ezinesantya esidibeneyo sokuhamba, zifuna ukubonwa okuthembekileyo kwabantu abame emnyango (ukubhekabheka, ukulinda abanye, ukuphatha iibhegi zokuthenga okanye iibriefcases), kwaye indawo yokubona kufuneka ichaneke ngokwaneleyo ukuze kuthintelwe ukuba abantu abahamba ngeenyawo badlule kwindlela esecaleni kwendlela.
Enye into eqhelekileyo yokusilela kwiindawo zokuthengisa kukuchaza i-M-254 engenaso isisombululo semitha esifanelekileyo kwizithuthi ezilindelekileyo. Kwindawo yokuthengisa enabantu abaninzi (ngaphezulu kwe-1,000 yokuhamba ngemini), ndicebisa ubuncinci imisebe eli-16 enesithuba esingama-25mm okanye esincinci. Oku kubonelela ngokubonakalayo kwabantwana kwaye kuqinisekisa ukuba ucango luhlala luvulekile lonke ixesha umntu esemnyango, nokuba bayama okanye bama ngequbuliso.
Udidi lwesicelo 2: Isibhedlele kunye neZibonelelo zezeMpilo
Izibonelelo zonyango zinemfuno eziyimfuneko ngokukodwa zokuchonga ucango ngokuzenzekelayo. Ukudibana kwezigulana ezihamba kancinci (ezihamba ngeenyawo, ezikwizihlalo ezinamavili, ezibhedini, ezikwii-gurney), izixhobo zonyango ezinokuthintela inxalenye yendawo yokubhaqwa, kunye nokubaluleka okubalulekileyo kokusebenza kocango okuthembekileyo kulawulo losulelo kunye nokuphendula ngokukhawuleza kuthetha ukuba kufuneka kuchazwe kuphela ubuchwepheshe bokubona obukwaziyo ukubakho.
Ngenxa yokuba iindawo zesibhedlele zifuna iingcango ezivulekela wonke umntu ofuna ukudlula kuzo — nokuba uhamba kancinci kangakanani okanye uphethe ntoni na — ikhethini ye-infrared esebenzayo ye-M-254 yiteknoloji yokubona eyimfuneko kwizicelo zonyango.Ngokuqhelekileyo sicebisa inani eliphezulu lemitha ekhoyo (iimitha ezingama-24 kwisithuba esingama-20mm) ukuqinisekisa ukugubungela ngokupheleleyo indawo yokufumanisa nokuba indawo ithintelwe kancinci ziindawo zokubeka ii-IV, izixhobo zokubeka esweni, okanye iireyile zokulala.
Kwiminyango yangaphakathi yesibhedlele phakathi kweendawo ezilawulwayo (iithiyetha ezisebenzayo, ii-ICU, amagumbi okuzihlukanisa), sihlala sicebisa ukuba kuchazwe ii-sensors ezimbini ze-M-254 kwisimo esingafunekiyo: esinye njenge-sensor yokuqala yokusebenza kunye nesinye njenge-sensor yokhuseleko lobukho ethintela ucango ukuba lungavali xa indawo yokubhaqwa isetyenziswa. Olu lungiselelo lwe-sensor ezimbini lubonelela ngokhuseleko kwimo yokusilela okukhulu kokuvalwa kocango kwisigulana.
Udidi lweSicelo 3: Iingcango zeShishini ezikhawulezayo
Iingcango zesantya esiphezulu zoshishino (ezisetyenziswa kwiindawo zokugcina impahla, kwiindawo zokugcina izinto ezibandayo, amagumbi acocekileyo, kunye neendawo zangaphakathi zezityalo zokwenza izinto) zineemfuno zokufumanisa ezahlukileyo kwiingcango zorhwebo. Eyona njongo iphambili yokusebenza sisantya somjikelo weengcango — iingcango zesantya esiphezulu zinokuvula kwimizuzwana eyi-0.8–2.0 kwaye zivale kwimizuzwana eyi-1.5–3.0, xa kuthelekiswa nemizuzwana eyi-3–5 kwiingcango zokutyibilika zorhwebo. Le mfuneko yesantya ithetha ukuba inkqubo yokufumanisa kufuneka ibonelele zombini ukusebenza kwentshukumo ekhawulezayo kunye nokhuseleko oluthembekileyo lobukho.
Kwiingcango zemizi-mveliso ezikhawulezayo, ukufunyanwa kwe-microwave kudla ngokuba yeyona ndlela iphambili yokuvula ngenxa yexesha layo lokuphendula elikhawulezayo kunye nokusebenza kwayo okugqwesileyo ngaphandle. Ikhethini ye-infrared ye-M-254 emva koko ichazwa njengesensor yokhuseleko lobukho besibini - efakwe kwisakhelo somnyango ukuze ikhethini ifikelele kubude bonke bokuvulwa komnyango, ithintele ucango ukuba lungavaleki ukuba kukho umntu okanye imoto esemnyango.Ngenxa yokuba umsebenzi wokhuseleko lobukho ubalulekile kukhuseleko, isenzi sokhuseleko se-M-254 kufuneka sifakwe kwi-input yokhuseleko yomlawuli womnyango ngendlela ekhuselekileyo ethintela ucango ukuba lungavaleki nokuba imeko yokusebenza komlawuli injani na ukuba isenzi sokhuseleko sibona ukuba sikhona..
Udidi lweSicelo 4: Indawo yokugcina izinto ezibandayo kunye neendawo ezibandayo
Iingcango zokugcina izinto ezibandayo zinomngeni okhethekileyo wokufumanisa: umahluko omkhulu wobushushu phakathi kwengaphakathi elibandayo kunye nengaphandle elifudumeleyo ubangela ukuxinana kunye nokuqokelelwa komkhenkce kwiilensi zesensor, nto leyo enokonakalisa ukusebenza kokufumanisa izinto ezikwi-infrared. Sikwaqaphele ukuba kwiindawo zokugcina izinto ezibandayo ezingaphantsi kwe--20°C, uluhlu olusebenzayo lokufumanisa ezinye iisensor ze-M-254 luyancipha nge-15–25% xa kuthelekiswa namaxabiso eenkcukacha zobushushu begumbi.
Kwizicelo zomnyango wokugcina ubushushu, ndicebisa indlela exutyiweyo: ukufunyanwa kwe-microwave njenge-sensor yokuqala yokuvula, kunye nekhethini le-infrared le-M-254 njenge-sensor yokhuseleko lobukho kuphela (hayi njenge-activation yokuqala). I-sensor ye-microwave ifakwe kwindawo efudumeleyo (ukuthintela ukuqokelelwa komkhenkce kwi-antenna) kwaye yenziwe ngendawo yokufumanisa efikelela kuphela kumda womnyango, inciphisa umngcipheko wokuqalisa umsebenzi kwindawo efudumeleyo ekufutshane. Ikhethini yokhuseleko ye-M-254 iyafudunyezwa okanye isuswe kwaye ichazwe ngomlinganiselo wobushushu obongezelelweyo ukuya kwi--40°C.
Iimpazamo eziQhelekileyo zeNkcazelo kunye nendlela yokuziphepha
Impazamo 1: Ukucacisa iMicrowave xa usetyenziso lufuna ukufunyanwa koBukho
Eyona mpazamo ixhaphakileyo kukukhetha ukufunyanwa kwe-microwave ngokusekelwe kwixabiso layo eliphantsi kunye nokufakelwa okulula, ngaphandle kokuqinisekisa ukuba usetyenziso lufuna ngokwenene ukufunyanwa okusekelwe kwintshukumo kunokuba kufumaneke. Ndiqikelela ukuba le mpazamo ibangela i-40–50% yezikhalazo zokufunyanwa kweminyango ngokuzenzekelayo esizifumanayo kwiYufan Beifan. Iimpawu ezibonisa ukusilela kwendlela ecothayo (iingcango ezingavulekiyo kubantu abasondela ngesantya), izinto ezibangela ubuxoki ezivela kwiindlela ezikufutshane, kunye nezikhalazo zabathengi malunga neengcango "ezinengqondo yazo."
Umbuzo omele ubuze wona ngowokuba: “Ngaba umntu omi emnyango ngokusengqiqweni ulindeleke ukuba afune ucango luvuleke okanye luhlale luvuliwe?” Ukuba impendulo ngu-ewe — kwaye phantse kuzo zonke iinkqubo zorhwebo nezezempilo — kufuneka ukufunyanwa kobukho (ikhethini ye-infrared esebenzayo ye-M-254) kufumaneke. I-microwave yodwa ifanelekile kuphela kwiingcango zemizi-mveliso ezihamba ngesantya esiphezulu apho imfuneko ephambili lixesha lokujikeleza ngokukhawuleza kwaye umsebenzi wokhuseleko lobukho uphathwa sisiva-sensor sokhuseleko esahlukileyo.
Impazamo 2: Ukucacisa i-M-254 Ngaphandle koKhuseleko olufanelekileyo lweNdalo
Impazamo yesibini eqhelekileyo kukuchaza ikhethini ye-infrared ye-M-254 kwisicelo sangaphandle okanye esingaphandle ngaphandle kokuqinisekisa umlinganiselo we-IP kunye nobubanzi bobushushu bokusebenza. Izinzwa eziqhelekileyo ze-M-254 zilinganiswe nge-IP54 (zikhuselwe emanzini atshizayo nakweyiphi na indlela kwaye zingangeni uthuli), nto leyo eyaneleyo kwiindawo zangaphandle ezigqunyiweyo kodwa azanelanga kwiindawo zangaphandle ezivezwe ngokupheleleyo kwiimeko zemozulu ezinemvula enkulu okanye amaqondo obushushu abandayo.
Kwizinto ezifakelwe ngaphandle ezivezwe ngokupheleleyo, ndicebisa ukuba kuchazwe izinzwa ze-M-254 ezinereyithingi ye-IP65 kunye nomgangatho wobushushu bokusebenza ukusuka kwi--30°C ukuya kwi-+70°C. Ezi yunithi ziquka iindibano zeelensi ezifudunyezwayo ezithintela ukwakheka komkhenkce kumaqondo obushushu angaphantsi kwengqele, nto leyo ebalulekileyo ekusebenzeni okuthembekileyo kwiindawo zokugcina izinto ezibandayo, kwiindawo zokulayisha ezingafudunyezwanga, kunye neengcango zangaphandle ezinemozulu epholileyo kwiimeko zasebusika.
Impazamo 3: Ukusebenzisa iTekhnoloji yokufumanisa enye kuphela xa kufuneka ezimbini
Abafaki abaninzi kunye nabachazi-magama baphatha i-microwave kunye ne-infrared njengetekhnoloji ezikhuphisanayo — khetha enye, hayi zombini. Le yimpazamo kwizicelo apho kufuneka zombini ukuvuselelwa okukhawulezileyo kunye nokhuseleko lobukho. Iingcango zemizi-mveliso ezikhawulezayo zezona zibalaseleyo: i-microwave sensor ibonelela ngokuvulwa okukhawulezileyo okusebenzayo okufunekayo ukugcina isantya somjikelo wocango, ngelixa ikhethini ye-infrared ye-M-254 ibonelela ngokhuseleko lobukho olufunekayo ukuthintela ucango ukuba lungavaleki kumqhubi we-forklift okanye umsebenzi we-warehouse osesemnyango.
Ngenxa yokuba indibaniselwano yokusebenza kwe-microwave kunye nokuchonga ubukho bokhuseleko lwe-infrared yeyona ndlela ilungileyo yokumisela iingcango zesantya esiphezulu zoshishino, ukucacisa iteknoloji enye kuphela kwezi zicelo kuyingozi yokhuseleko kunye nomda wokusebenza.Ixabiso eliphantsi lokongeza isenzi sesibini lidla ngokuba yi-30–50% yexabiso lesenzi esiphambili, kwaye iingenelo zokhuseleko kunye nokusebenza zinkulu.
Impazamo 4: Ukungayingqinisi imida yeNdawo yokuFumanisa ngaphambi kokuba kugqitywe iinkcukacha
Indawo yokubhaqwa kwe-sensor ye-microwave idla ngokulungiswa nge-sensitivity potentiometer ye-sensor okanye useto lwe-DIP switch, kodwa imo yendawo yokubhaqwa emiselweyo - ikhowuni ephuma kwi-sensor - idla ngokuba banzi kakhulu ukuba ingafakelwa kwiindawo ezixineneyo zabahambi ngeenyawo. Ndibone ukufakelwa okuninzi apho i-sensor ye-microwave yayibangela ukuba abahambi ngeenyawo badlule kwindlela yabahambi ngeenyawo iimitha ezi-5 ukusuka emnyango, nto leyo ebangela ukuba ucango luvuleke xa kungekho ndlela yokungena.
Ngaphambi kokuba ucacise i-microwave sensor kuyo nayiphi na inkqubo yorhwebo okanye yokuthengisa, hamba ngqo kwindawo yokufakela ecetywayo kwaye uchonge yonke imithombo enokubakho yokuhamba okungafunekiyo ngaphakathi kwerediyasi yeemitha ezili-10 ukusuka kwindawo ye-sensor. Lungisa indawo yokufumanisa ukuze ungabandakanyi yonke imithombo ye-trigger engafunekiyo, okanye ucacise ikhethini ye-infrared ye-M-254 endaweni yoko, edala indawo yokufumanisa echazwe ngokuchanekileyo yipateni ye-physical beam phakathi kwe-emitter kunye ne-receiver.
Iingcebiso zokuthenga: Indlela yokuchaza inkqubo efanelekileyo yokuchongwa kweprojekthi yakho
Ngokusekelwe kumava ethu okuxhasa amakhulu eeprojekthi zeengcango ezizenzekelayo kuzo zonke iindidi zezicelo, nantsi uluhlu lokuhlola olusebenzayo lokuthenga endilucebisayo kumthengi ngamnye ovavanya iinkqubo zokufumanisa iingcango ezizenzekelayo.
- Chaza imfuneko yokuqala yokufumanisa:Ingaba isicelo sakho sifuna ukufunyanwa kobukho (umntu emi engashukumi), ukufunyanwa kwentshukumo (umntu osondelayo), okanye zombini? Ubukho kuphela → M-254. Ukunyakaza kuphela ngesantya esiphezulu → i-microwave. Zombini iimfuno → uqwalaselo oluxutyiweyo.
- Qinisekisa iimeko zokusingqongileyo:Ngaba kufuneka ifakwe ngaphakathi, ngaphandle, okanye ngaphandle? Ingaba kufuneka ifakwe njani? Ingaba i-sensor ibekwe emvuleni ngqo, ekhephuni, eluthulini, okanye kumswakama ophezulu? Thelekisa umlinganiselo we-IP kunye nenkcazo yobushushu neemeko zokusingqongileyo — kungekhona kwiimeko ezilindelekileyo.
- Jonga isisombululo sokuchongwa kweprofayili yakho yetrafikhi:Ukuba ucango luza kunceda abantu abaninzi abahamba ngeenyawo kuquka nabantwana, abantu abadala abanezixhobo zokuhamba, okanye izilwanyana ezincedisayo, chaza i-M-254 enomlinganiselo ophezulu wemitha (iimitha ezili-16 nangaphezulu, isithuba esingama-25mm okanye esincinci). Kwindlela eqhelekileyo yokuhamba ngeenyawo yabantu abadala, imimitha ezi-8–12 kwisithuba esingama-40–50mm yanele.
- Qinisekisa ukuba ulungiselelo lwemveliso luhambelana nomlawuli womnyango wakho:Ii-sensors ze-M-254 kunye ne-microwave ziyafumaneka kunye ne-relay output (uqhagamshelwano olomileyo, olufanelekileyo kubalawuli abaninzi beminyango) kunye ne-solid-state output (i-PNP okanye i-NPN, efanelekileyo kubalawuli abasekwe kwi-PLC). Qinisekisa uhlobo lwe-output ngaphambi koku-odola — uqwalaselo lwe-output olungahambelaniyo yimpazamo eqhelekileyo yokufakela enokubangela ukusebenza okwethutyana okanye ukungaphumeleli kwenkqubo ngokupheleleyo.
- Isicwangciso sokufikelela kulondolozo:Izinzwa ze-infrared curtain zifuna ukucocwa kweelensi rhoqo kunye nokuqinisekiswa kokulungelelaniswa kwemisebe, ngakumbi kwiindawo ezinothuli okanye ezingaphandle. Cacisa imodeli yesensa evumela ukufikelela kweelensi ngaphandle kokususa yonke indibano yesensa kwisakhelo somnyango. Izinzwa ezifuna ukuqhaqhwa ngokupheleleyo ukuze kucocwe ilensi zonyusa ixesha lokugcinwa kwazo ngamanani ama-3–5.
- Cinga ngokufakelwa kwe-hybrid kwiindawo ezifuna kakhulu:Ukuba isicelo sakho sineempawu ezilandelayo — ukusebenza komnyango ngesantya esiphezulu, ukubonakala ngaphandle, ukuhamba kwabantu abahamba ngeenyawo kunye nezithuthi ezahlukeneyo, okanye ubushushu obuphezulu — cwangcisa inkqubo yokubona i-hybrid kwasekuqaleni endaweni yokongeza i-sensor yesibini njenge-retrofit emva kokuba i-sensor yokuqala ingabonakali ifanelekile.
