Ukusebenza kwezindleko eziphezulu kanye ne-multifunction ye-4G DTU
Idizayini yesakhiwo soxhumano lwetheminali, elula kakhulu kwizinhlelo zokusebenza zemboni, ukuhlelwa kweskripthi sokusekela, futhi ingaqoqa idatha ngokuzenzakalelayo ensimbini nasekuqondisweni kabili.ukudluliswa okusobala.
Incazelo Yezingxenyekazi zekhompuyutha
Isebenzisa ama-chips okuxhumana e-ZTE, isekela ama-7 pattern 15 frequency brands 4G network, uma kwenzeka inethiwekhi ye-4G ingazinzi, ingashintshela kunethiwekhi ye-2/3G ukuze kuqinisekiswe ukuthi okokusebenza kuxhumeke njalo, futhi kushintshele kunethiwekhi ye-4G ngokuzenzakalelayo lapho i-4G inethiwekhi ibuyiselwe.

Incazelo Yomsebenzi Oyinhloko
Sekela iphrothokholi eminingi
TCP-ZSD / UDP-ZSD
Isekelwe ku-Mind Packing Iphethini ye-TCP/UDP. Iphakheji ye-SKD esiyihlinzeka yithi isekela imvelo yokuthuthukisa ulimi lwezinhlelo eziningi, umsebenzisi angavakashela kalula isikhungo sedatha ngaphandle kokunakekela mayelana nephrothokholi yenethiwekhi eyinkimbinkimbi . isekela i-IP emile, isizinda esiguqukayo, inethiwekhi yangasese ye-APN.
Iphrothokholi ye-HTTP
Iphrothokholi ye-HTTP ingasetshenziswa njengeklayenti le-HTTP ekudluliselweni kwedatha kanye nokuxhumana okukabili neseva ye-HTTP ukuze kube lula ukuthuthuka kobunzima.
Isebenzisa iphrothokholi ye-HTTP, lapho imbobo ye-serial inedatha okufanele ithunyelwe, isungula ukuxhumana neseva futhi ihambise i-DTU ID kanye nephakethe ledatha eliqoqiwe kuseva ngayinye ye-HTTP ngeposi le-HTTP noma i-HTTP get. Ngale ndlela, idatha eqoqwe yi-DTU ingaboniswa ngokuqondile ohlangothini lwe-WEB.
Umsebenzi we-Virtual Serial Port
Ngokusebenzisa ubuchwepheshe be-serial port ubuchwepheshe, kungenzeka ukusungula uxhumano olungenantambo lwe-4G olunesivinini esikhulu phakathi kwedivayisi ye-serial port kanye nekhompyutha ebamba esikhungweni sedatha nge-DTU futhi wenze uxhumano olunezintambo olubonakalayo, olunohlelo lwangempela lwembobo ye-serial idivayisi yomsebenzisi.
Ukuthuthukiswa Kwendawo/Ukude
isekela amapharamitha wokucushwa akude futhi uthuthukise i-firmware esikhungweni sokuqapha, idivayisi izosebenza njengokujwayelekile lapho ithuthukiswa ukude.
Ukuhlelwa kweskripthi kugumbuqela i-DTU evamile, enomsebenzi wokudlulisa idatha kuphela, futhi kuguqule i-MDD3411 ibe idivayisi ye-DTU enomsebenzi wokuthola.
Naka imanuwali yomsebenzisi yeskripthi sokutholwa kwendawo ye-DTU
ehlukile kune-DTU yangaphambilini, umsebenzi wokutholwa kweskripthi wokusekela we-MDD3411. Ngokusebenzisa imiyalelo yombhalo, abasebenzisi bangachaza ukutholwa kwedatha kalula, kunciphisa kakhulu izindleko zehadiwe.
Ukuchaza isenzo sasendaweni sokutholwa kuyavumelana nezimo
Umbhalo wangokwezifiso ungabona ukutholwa okuzenzakalelayo kwenzwa yangaphandle kanye nedatha yensimbi nge-DTU ngaphandle kwesidingo sokuthi umsebenzisi engeze isilawuli ngokuhlukana.Ukuthola isikhathi okuzenzakalelayo kwe-DTU kungenziwa ngomyalo weskripthi ukuze kulungiselelwe i-DTU, enciphisa kakhulu izindleko zehardware yokutholwa. Umbhalo uqaphela imisebenzi eyisisekelo yokulawula ukushintsha, ukulawula ukubambezeleka, ukukhishwa kwemiyalo, ukulawula ukujikeleza, ukulawula ukubika, ukufaka unhlokweni womlayezo wangokwezifiso, kanye nokuthi ukwamukela yini ukuguqulwa kwezinga le-baud lokuphendula kwensimbi, njll., okungahlangabezana nezimfuneko zokutholwa izinsimbi eziningi.
I-MDD3411 isebenzisa ubuchwepheshe be-patch obuthuthukisiwe
Ngokudlula kwembobo, i-overvoltage, uxhumano olunqanda ukuhlehla kanye nokuvikela okunqanda ukukhuphuka, ikhwalithi yezinga lezimboni, ukusebenza okuzinzile kokuthi -40~85℃;Uma uxhumo lwezintambo luhlehliswa ngokungalindelekile futhi imbobo iyisiyingi esifushane, idivayisi ngeke yonakele, futhi ingasetshenziswa ngokujwayelekile ngemva kokuxhuma kabusha.
