Kwiimodeli eziphazamisayo (ezifana neenzwa ezingaphantsi komhlaba), qinisekisa ukuba zibekwe kude neezantsi zeetanki (ukuthintela ukwakheka kwedaka) kwaye ziqiniswe ngokuqinileyo ukuthintela intshukumo. Ukulinganisa lelinye inyathelo elibalulekileyo: uninzi lwabavelisi lucebisa ukulinganisa iimitha zamanqanaba ngaphambi kokusetyenziswa kokuqala kwaye emva koko minyaka le, besebenzisa imigangatho yesalathiso ukuqinisekisa ukuchaneka.
Iimfuneko zokugcinwa zincinci, kodwa kusafuneka uhlolo oluqhelekileyo. Kwiimitha ze-ultrasonic, hlamba i-transducer (inxalenye ekhupha/efumana amaza) rhoqo ukuze ususe uthuli, ioyile, okanye intsalela—oku kuqinisekisa ukuhanjiswa kwesignali okucacileyo. Kwiimitha ezintywiliselwa emanzini, hlola intambo kwaye uyivale ukuze ubone umonakalo (umz., imingxunya evela ekukrazukeni) ukuze uthintele ukungena kwamanzi. Iimitha ezininzi zamanqanaba zanamhlanje nazo ziquka iimpawu zokuzixilonga, ezifana nezilumkiso zebhetri ephantsi, ukulahleka kwesignali, okanye ukungcola kwesensor, okuvumela abaqhubi ukuba bajongane nemiba ngaphambi kokuba ichaphazele ukusebenza. Kwiindawo ezingcolisayo, jonga izindlu zeemitha kunye neesensor ukuze ubone iimpawu zokuguguleka (umz., umhlwa kwintsimbi engagqwaliyo) kwaye utshintshe iindawo njengoko kufuneka ukuze uphephe ukungaphumeleli.
Iindlela Zexesha Elizayo
Njengoko iteknoloji itshintsha, iimitha zamanqanaba zimiselwe ukuba zibe krelekrele ngakumbi kwaye zihlanganiswe. Enye indlela ephambili kukunxibelelana kwe-IoT: iimitha zamanqanaba ezizayo ziya kuhambisa idatha yexesha langempela kumaqonga asekelwe efini nge-Wi-Fi, i-LoRaWAN, okanye i-5G. Oku kuvumela ukujonga kude—abaqhubi banokujonga amanqanaba eetanki kwifowuni okanye kwikhompyutha, nokuba kwiitanki ezikwiindawo ezikude (ezifana namaqonga aselunxwemeni okanye imithombo yamanzi yasemaphandleni). Uhlalutyo olusebenzisa i-AI luya kudlala indima: ngokuhlalutya idatha yamanqanaba embali, ezi nkqubo zinokuqikelela iipateni zokusetyenziswa kwixesha elizayo (umz., xa itanki yamanzi iya kufuna ukuzaliswa kwakhona) okanye zibone izinto ezingaqhelekanga (umz., ukwehla ngequbuliso kwinqanaba leoyile okubonisa ukuvuza), okuvumela ukwenza izigqibo ngokukhawuleza.
Enye indlela yokwenza izinto kukwenza izinto zibe lula kwaye zithwaleke lula. Iimitha zamanqanaba ezincinci nezisebenza ngebhetri ziya kuba yinto eqhelekileyo ekusetyenzisweni endle—umzekelo, izazinzulu zokusingqongileyo ezilinganisa amanqanaba amanzi kumachibi akude, okanye iingcali ezihlola amatanki amancinci kwimizi-mveliso engenazo iinkqubo zokubeka esweni ezisisigxina. Ezi zixhobo ziya kuba lula, kube lula ukuzilinganisa, kwaye zikwazi ukugcina idatha ukuze ihlalutywe kamva.
Okokugqibela, ukuhambelana okuphuculweyo neefektri ezikrelekrele kuya kuba yinto ephambili. Iimitha zamanqanaba ziya kudibana ngokungenamthungo neenkqubo ze-Industry 4.0, zabelane ngedatha nee-PLC (Programmable Logic Controllers) kunye nesoftware ye-SCADA (Supervisory Control and Data Acquisition). Olu manyano luya kuzenzela iinkqubo—umzekelo, lubangele ipompo ukuba izalise itanki xa amanqanaba ehla ngaphantsi komda—ukunciphisa ukungenelela kwabantu kunye nokuphucula ukusebenza kakuhle.
