• usebenzisa i-6 ~ 30V ububanzi bombane obanzi kunye noyilo lwenja yokubukela, ukuqinisekisa ukuba umsebenzi uzinzile kulo naluphi na uhlobo lweemeko zesicelo.

Iiparamitha zesixhobo

INkcazelo yoMsebenzi oPhambili

Ixhasa iprotocol ezininzi

TCP-ZSD / UDP-ZSD

Isiseko kwi-Mind Packing TCP / UDP iphethini. Ipakethe ye-SKD ibonelelwa ngathi ixhasa imo yophuhliso lwenkqubo yolwimi oluninzi, umsebenzisi unokutyelela ngokulula iziko ledatha ngaphandle kokukhathalela malunga neprotocol eyinkimbinkimbi yenethiwekhi. Ixhasa i-IP engatshintshiyo, isizinda esiguqukayo, inethiwekhi yabucala ye-APN.

Iprotocol yeHTTP

I-protocol ye-HTTP ingasetyenziswa njengomthengi we-HTTP yokuhanjiswa kwedatha kunye nonxibelelwano lwe-bidirectional kunye nomncedisi we-HTTP ukwenza lula ubunzima bophuhliso.

Ukusebenzisa i-HTTP protocol, xa i-port ye-serial inedatha yokuthunyelwa, iseka uxhulumaniso kunye nomncedisi kwaye ingenise i-ID ye-DTU kunye nepakethi yedatha eqokelelweyo kwi-server nganye ye-HTTP ngeposi ye-HTTP okanye i-HTTP get. Ngale ndlela, idatha eqokelelwe yi-DTU inokuboniswa ngokuthe ngqo kwicala leWEBHU.

Umsebenzi wePort Uthotho lweVirtual

Ukusebenzisa iteknoloji ye-serial ye-port ye-virtual port, kuyenzeka ukuseka uqhagamshelwano olungenazingcingo lwe-4G olunesantya esiphezulu phakathi kwesixhobo se-serial port kunye ne-computer yomkhosi kwiziko ledatha ngokusebenzisa i-DTU kwaye wenze udibaniso olunentambo olunenyani, olunenkqubo yoqobo yeserial yezibuko. isixhobo somsebenzisi.

Uphuculo lwasekuhlaleni/ olukude

Ukuxhasa iiparamitha zoqwalaselo ezikude kunye nokuphucula i-firmware kwiziko lokujonga, isixhobo siya kusebenza njengesiqhelo xa uphucula ukude.

Inkqubo yeskripthi ibhukuqa i-DTU yemveli, enomsebenzi wokuhanjiswa kwedatha kuphela, kwaye ijika i-MDD3411 ibe sisixhobo se-DTU esinomsebenzi wokufumana.

Qaphela i-DTU yeskripthi yeskripthi yomyalelo wencwadi yomsebenzisi

eyahlukileyo kwi-DTU ngaphambili, i-MDD3411 yenkxaso yeskripthi yokufumana umsebenzi ngokuzenzekelayo. Ukusebenzisa umyalelo weskripthi, abasebenzisi banokuchaza ukufunyanwa kwedatha ngokuguquguqukayo, kunciphisa kakhulu iindleko ze-hardware.

Ukuchaza intshukumo yokufumana indawo ebhetyebhetye

Isikripthi sesiko sinokuqonda ukufunyanwa ngokuzenzekelayo kwenzwa yangaphandle kunye nedatha yesixhobo nge-DTU ngaphandle kwesidingo somsebenzisi ukongeza isilawuli ngokwahlukileyo.Ixesha le-DTU lokufumana ixesha elizenzekelayo liyakwazi ukuphunyezwa ngomyalelo weskripthi ukuqwalasela i-DTU, eyanciphisa kakhulu i-hardware yokufumana iindleko. Umbhalo uqaphela imisebenzi esisiseko yolawulo lokutshintsha, ulawulo lokulibazisa, ukukhutshwa komyalelo, ulawulo lokujikeleza, ulawulo lokunika ingxelo, ukufaka umbhalo ongasentla kwentloko yomyalezo, kwaye nokuba uyamkelwa na utshintsho lwesantya se-baud yempendulo yesixhobo, njl., esinokuhlangabezana neemfuno zokufunyanwa kwezixhobo ezininzi.

I-MDD3411 yamkela itekhnoloji yepetshi ephezulu

Nge-port overcurrent, overvoltage, anti-reverse connection kunye nokhuseleko oluchasayo, umgangatho we-industrial-grade, umsebenzi ozinzileyo kwi -40 ~ 85 ℃; Ukuba uxhulumaniso lwecingo lubuyiselwe umva ngokungalindelekanga kwaye izibuko lifutshane, isixhobo asiyi kuba. yonakele, kwaye ingasetyenziswa ngokuqhelekileyo emva kokudibanisa kwakhona.
