Eminyakeni yamuva nje, isimo sokuthuthukiswa komnotho nobuchwepheshe bomhlaba wonke siye sashintsha kakhulu. Siqhutshwa yisizukulwane esisha sobuchwepheshe bolwazi nobuchwepheshe bokuxhumana, umnotho wangempela wezwe lami uye wathuthukisa njalo izinga lawo lobuchwepheshe, ukuxhumana, kanye nobuhlakani. Umnotho wedijithali ufinyelele ukukhula okusheshayo, hhayi nje kuphela kokudala nokusha. Ukuguqulwa kwamandla e-kinetic kudlale indima ebalulekile enjinini, futhi kuye kwaba ukusekelwa okuqinile kokuguqulwa nokuthuthukiswa kwezimboni zendabuko.
Njengamanje, "ingqalasizinda entsha" isheshisa ukuqaliswa kwesizukulwane esisha sobuchwepheshe bolwazi nokuxhumana njengobuhlakani bokwenziwa, i-5G, i-blockchain, i-Internet of Things, i-cloud computing, njll., ukusungula izinto ezintsha kanye nokuthuthukiswa kuyasheshiswa kakhulu, futhi ukuhlanganiswa nezinkambu zezomnotho nezenhlalo kuya ngokuya kujula, kukhuthaza "i-Internet of Everything" kanye nokufika kwangempela kwesikhathi sempilo ehlakaniphile. Kulesi simo, intuthuko esheshayo yamadolobha ahlakaniphile, ukuphepha okuhlakaniphile, ezokuthutha ezihlakaniphile, ukuvikelwa komlilo okuhlakaniphile, amafektri ahlakaniphile, njll., kuqhubeke nokukhulisa isidingo semishini ehlakaniphile.
Kusukela ngo-2019, imali engenayo embonini yezinsimbi zasekhaya ikhule kancane kancane, futhi ukusetshenziswa kwezinsimbi ezihlakaniphile namamitha ahlonyiswe ngezinzwa ezahlukahlukene ezithuthukisiwe kuye kwanda kakhulu. Ngokusobala, uchungechunge lwezinto ezinhle njengokwanda kwesidingo semakethe kanye nokusekelwa kwezinqubomgomo zikazwelonke kuhlinzeke ngezimo ezinhle zokuthuthukiswa kanye nokwaziswa kwezinsimbi ezihlakaniphile. Ekusetshenzisweni kwezinsimbi ezihlakaniphile, ama-pressure gauge abelokhu eyindawo ebalulekile yokuhlukanisa.
Abantu abangaphakathi embonini bakholelwa ukuthi ngokuguqulwa okuqhubekayo kokukhiqiza kwezimboni kanye noshintsho ezidingweni zokukhiqiza nezokuphila, kuzoba nezimo eziningi zokusetshenziswa ezidinga ukukala ingcindezi encane yegesi, umusi, izinga loketshezi, njll., kanye nalolu hlobo lwethuluzi lokulinganisa ingcindezi encane. Ibizwa ngokuthi i-differential pressure transmitter. Njengomhlinzeki wesevisi odumile wasekhaya osekelwe ku-smart sensor-based interface, iShanghai Mingkong iklame futhi yathuthukisa uchungechunge lwe-MD-S221 lwama-differential pressure transmitters ukuphendula izidingo ezingenhla.
Kusukela ezidingweni zangempela zemakethe kanye namakhasimende, lesi sithumeli sokucindezela okuhlukile sochungechunge lwe-MD-S221 saseShanghai Mingkong sisebenzisa inzwa yokucindezela okuhlukile yokuqala engenisiwe njengento yokuzwa ingcindezi, futhi sihlonyiswe ngesekethe yokulungisa yedijithali esetshenziswa ngamandla aphansi kakhulu, enokunemba okuphezulu, Izinzuzo ezibalulekile njengokuqina okuhle kwesikhathi eside, ukunemba kungcono kune-1% FS.
Ngesikhathi esifanayo, i-MD-S221 differential pressure transmitter ingaveza ukuboniswa kwedijithali kwe-LED yedijithali yesikhathi sangempela; ukuphuma okungu-4-20mA/RS485 kuyakhethwa; futhi kunemisebenzi efana nokushintsha nokuhlanza amayunithi; futhi isekela ukusetha kwedijithi yekheli/isilinganiso se-baud/isihlungi okungaguquki /Isibonisi (uhlobo lwe-RS485); Umkhiqizo unomklamo wokuphazamiseka kwe-anti-electromagnetic ukuze kufezwe idatha ezinzile nethembekile; futhi unesitifiketi sokuvikela ukuqhuma se-Exia IICT4 Ga.
Ngaphezu kwalokho, i-Mingkong's micro differential pressure transmitter inosayizi wendlu ongu-83.7×83.7mm futhi yenziwe ngezinto ze-ABS. Ingafinyelela i-voltage yokunikezwa kwamandla engu-12~28V kanye nokushisa okusebenzayo okungu--40~80℃. Inezici zezinhlelo zokusebenza ezahlukahlukene. Ifaneleka kakhulu ezinkambeni ezidinga ukuqapha ingcindezi ye-micro-differential, njengezinhlelo zokungenisa umoya, izinhlelo zokuvimbela umlilo nentuthu kanye nokukhipha umoya, ukuqapha abalandeli, izinhlelo zokuhlunga umoya opholile, njll.
