Ubuchwepheshe buye bandisa izinhlobo eziningi zamandla abantu, futhi inzwa yandise ububanzi bokubona komuntu.Ngokuthuthuka okusheshayo kobuchwepheshe besimanje.Kunesidingo esikhulu se-IoT, idatha enkulu, ubuchwepheshe be-cloud computing nokunye.Isetshenziswa kakhulu kwezomnotho, isayensi yezokuvikela kazwelonke nobuchwepheshe, impilo yabantu kanye nanoma yiziphi ezinye izindawo.
Ukuqonda Izinzwa Nenhloso Yazo
Kuyihlathi laphaya elinezinhlobo zezinzwa ezingenakubalwa.Kusukela kuzinzwa zokushisa ezithobekile kuya ezinhlelweni ze-LiDAR eziyinkimbinkimbi, zonke zinendima eyingqayizivele emhlabeni wethu oqhutshwa ubuchwepheshe.Ngakho-ke, isinyathelo sokuqala sokukhetha inzwa efanele ukuqonda ukuthi benzani.
Izinzwa zingamehlo nezindlebe zedivayisi yethu, zinikeza idatha ebalulekile evela emhlabeni obonakalayo.Baqapha izici zemvelo, babone izinguquko, futhi badlulisele lolu lwazi kwezinye izingxenye zesistimu.Iyiphi inzwa oyikhethayo incike kakhulu kulokho ofuna ukukukala.
Izinhlobo zezinzwa
Izinhlobonhlobo zezinzwa zingenza ikhanda lakho lizule!Nasi isifinyezo sezinye ezivame kakhulu:
1. Izinzwa Zezinga lokushisa: Njengoba igama liphakamisa, lezi zilandelela ukuhlukahluka kwezinga lokushisa.Ziyisinkwa nebhotela lezinhlelo ze-HVAC nezinqubo eziningi zezimboni.
2. Izinzwa ze-Proximity: Isebenza kahle kumarobhothi namasistimu okuvikela, lezi zinzwa zithola ubukhona noma ukungabikho kwento phakathi kwebanga elithile.
3. Izinzwa Zokucindezela: Ukuqapha umoya noma umfutho we-fluid amandla azo.Uzozithola ezimotweni, kumishini yezokwelapha, namasistimu okuqapha isimo sezulu.
4. Izinzwa zokukhanya: Lezi zibona amazinga okukhanya futhi zivame ukusetshenziswa ezinhlelweni zokukhanyisa ezizenzakalelayo namakhamera.
Ngakho-ke ngokujwayelekile, Futhi izinzwa zihlukaniswe inzwa engenantambo kanye nenzwa evamile enezintambo.
Izinzwa ezinezintambo ezivamile zixhuma idivayisi ethola okokufaka, inenzuzo yokunemba okuphezulu, ihlala isikhathi eside futhi ingasetshenziswa izikhathi eziningi ngaphandle kokushintshwa.
Inzwa engenantambo ingumqoqi wokuxhumana kwedatha okungenantambo ohlanganisa imisebenzi yokutholwa kwedatha, ukuphathwa kwedatha nokuxhumana kwedatha, inenzuzo yokusebenza kwamandla aphansi, ukuthuthwa kwedatha okungenantambo, akukho zintambo, ukufakwa okuguquguqukayo nokulungisa iphutha njalonjalo.
Izinqubo zokuxhumana zihlukaniswe zaba yizivumelwano zokuxhumana okungenawaya kanye nezinqubo zokuxhumana ezinezintambo.Iphrothokholi yokuxhumana ichaza ifomethi esetshenziswa iyunithi yedatha, ulwazi kanye nencazelo okufanele iyunithi yolwazi ibe nayo, imodi yokuxhuma, kanye nesikhathi lapho ulwazi luthunyelwa futhi lwamukelwe, ukuze kuqinisekiswe ukudluliswa kwedatha ngokushelelayo endaweni enqunyiwe.
Izinhlobo zezinqubo zokuxhumana zineI-RFID, i-infrared, i-ZigBee, i-Bluetooth, i-GPRS, i-4G, i-Wifi ne-NB-IoT.Izivumelwano zokuxhumana nazoI-MBus, i-USB, i-RS232, i-RS485 ne-ethernet.
Eminye imininingwane Yephrothokholi ngayinye kanjena:
A: Amaphrothokholi Angenantambo
Ukuxhumana okungenantambo sekuyingxenye ebalulekile yobuchwepheshe besimanje.Kusukela kumathoyizi okulawula kude ukuya emishinini yezimboni ethuthukisiwe, izivumelwano ezingenantambo zidlala indima ebalulekile.Nazi ezinye ezivamile:
1. I-RFID(I-Radio Frequency Identification): I-RFID isetshenziselwa ukushintshanisa idatha ngaphandle kokuthinta, ngokuvamile kakhulu ekulawuleni ukufinyelela namasistimu okulandelela impahla.
2. I-infrared:Ukuxhumana kwe-infrared kusetshenziswa ezinhlelweni zebanga elifushane, njengamarimothi kamabonakude kanye nokudluliswa kwedatha yebanga elifushane phakathi kwamadivaysi.
3. I-ZigBee:I-ZigBee inethiwekhi engenantambo enamandla aphansi, enezinga eliphansi ledatha esetshenziswa ikakhulukazi kuzilungiselelo zezimboni, amakhaya ahlakaniphile, namasistimu okulawula kude.
4. I-Bluetooth:Cishe uyamazi lo!I-Bluetooth isetshenziselwa ukuxhumana kwebanga elifushane, ukukhomba-ephuzwini, kanye nokuxhumana okukhomba kuya kumaphuzu amaningi.Ilungele ukuxhuma ama-peripherals njengamakhibhodi, amagundane, nama-headphone.
5. I-GPRS(I-General Packet Radio Service): I-GPRS isetshenziswa ekuxhumaneni kweselula ukuze uthole i-inthanethi, imiyalezo ye-multimedia, kanye nezinsiza ezisekelwe endaweni.
6. 4G:Isizukulwane sesine sobuchwepheshe bamaselula, i-4G inikeza ukufinyelela kwe-inthanethi kwe-ultra-broadband kumaselula, ama-laptops, namanye amadivaysi eselula.
7. I-Wifi:I-Wifi iyiphrothokholi yenethiwekhi engenantambo evumela amadivayisi ukuthi axhumane ngaphandle kokuxhumeka kwekhebula okuqondile.Isetshenziswa kakhulu kumanethiwekhi asekhaya, amanethiwekhi ehhovisi, nasezindaweni ezidonsela umphakathi.
8. I-NB-IoT(I-Narrowband Internet of Things): I-NB-IoT iphrothokholi yenethiwekhi yendawo ebanzi enamandla aphansi eklanyelwe ukuxhuma amadivayisi kumabanga amade ezindaweni okunzima ukufinyelela kuzo.Ilungele izinhlelo zokusebenza ze-IoT.
B: Amaphrothokholi anezintambo
Nasemhlabeni wethu ongenazintambo, izivumelwano ezinezintambo zisenendima ebalulekile, ikakhulukazi ezimbonini nasezinhlelweni zokusebenza ezinezinga eliphezulu ledatha.
1. MBus (Meter-Bus):I-MBus iyindinganiso yaseYurophu yokufunda kude kwamamitha okushisa namanye amamitha okusebenzisa.
2. I-USB (Universal Serial Bus):I-USB isetshenziselwa ukuxhuma, ukuxhumana, kanye nokunikezwa kwamandla phakathi kwamakhompyutha namadivaysi awo angaphandle.
3. RS232:Leli izinga lokudluliswa kwedatha kokuxhumana kwe-serial.Ngokuvamile isetshenziswa kumachweba we-serial wekhompyutha.
4. RS485:Ngokufanayo ne-RS232, i-RS485 isekela ama-node engeziwe ngenethiwekhi ngayinye nobude bekhebula ende.Isetshenziswa ezinhlelweni zokulawula izimboni kanye nokwakha ezishintshayo.
5. I-Ethernet:I-Ethernet isetshenziswa kabanzi kumanethiwekhi wendawo (LANs).Inikeza isivinini esikhulu nokuxhumana okuthembekile phakathi kwamadivayisi.
Ukukhetha iphrothokholi efanele kuzoncika kakhulu kuhlelo lokusebenza nendawo ezungezile.Hlala ucabangela izici ezifana nobubanzi, ukusetshenziswa kwamandla, isilinganiso sedatha, nohlobo lwamadivayisi axhunywayo uma wenza ukukhetha kwakho.
Ngo-1983, ngokusekelwe ezingeni le-RS-422 Industrial Bus, i-Electronic Industry Association yakha futhi yakhipha izinga le-RS-485 Industrial Bus.Izinga lebhasi le-RS-485 licacisa izindinganiso zezakhiwo zikagesi zezindawo zebhasi ezichazwe ezifundeni ezimbili ezinengqondo: Izinga eliphozithivu liphakathi kuka-+2V ~ +6V, okubonisa isimo esinengqondo;Izinga elingalungile eliphakathi kuka -2V kanye -6V libonisa esinye isimo esinengqondo.Isignali yedijithali isebenzisa imodi yokudlulisa ehlukile, enganciphisa ngempumelelo ukuphazamiseka kwesignali yomsindo.
Ingakwazi ukusekela ngempumelelo ama-sub-node amaningi, ibanga lokuxhumana kanye nokuzwela okuphezulu kokwaziswa kokwamukela.Kunethiwekhi yokuxhumana yezimboni, ibhasi le-RS - 485 lisetshenziswa kakhulu ekudluliselweni kolwazi olujwayelekile nangaphandle kanye nokushintshaniswa kwedatha, zonke izinhlobo zemishini yezimboni enamandla okucindezela umsindo, izinga lokudluliswa kwedatha elisebenza kahle kanye nokuthembeka okuhle kokudluliswa kwedatha kanye nobude bekhebula lokuxhumana olwesabekayo. engenakuqhathaniswa nezinye izindinganiso eziningi zokuxhumana zezimboni.Ngakho-ke, i-RS-485 isetshenziswe kabanzi emikhakheni eminingi.
Iphrothokholi yokuxhumana ye-HENGKOizinga lokushisa kanye nomswakama inzwafuthiinzwa yegesiiRS-485.Ezingeni lokushisa kanye nomswakama kanye nomtshina wegesi, ibhasi le-RS-485 lingadlulisela ulwazi futhi lishintshisane ngedatha ngokuqondile nenzwa ukuze kuqinisekiswe idatha Ukusabela okusheshayo nokunemba.
Ngaphezu kwalokho, i-i-gas sensor probenjengento yokulinganisa inomthelela omkhulu ekunembeni kokulinganisa kwenzwa.Ngokusho kwemvelo ehlukene yokulinganisa yenzwa, kubaluleke kakhulu ukukhetha izindlu ze-probe.Njengendlu yensimbi engenasici inenzuzo yokumelana nokushisa okuphezulu,anti-ukugqwala, ukungangeni kwamanzi, ukususwa kothuli, kuyatholakala ekushiseni okuphezulu nomswakama, uthuli olukhulu nezinye izindawo ezinzima.
Ngokuthuthuka okuqhubekayo kobuchwepheshe, imfuneko yenzwa ehlukahlukene iphezulu kakhulu.
I-HENGKO ineminyaka engaphezu kweyi-10 yokuhlangenwe nakho okwenziwe ngokwezifiso kwe-OEM/ODM nokuklama ngokubambisana kochwepheshe
kanye namandla okuklama okusizwayo.Sinethimba lokuklama lochwepheshe elihlinzeka ngosizo lobuchwepheshe.
Sizokunikeza izinga lokushisa elihle kakhulu kanye nenzwa yomswakama / isidlulisi / uphenyo, igesiinzwa/i-alamu/module/isici nokunye.
