Ubukhulu Bomshini

Isingeniso Somsebenzi

Sekela ukuguqulwa okuzenzakalelayo kumodi ye-inthanethi, ye-IDLE, ne-PSM ukuze uzuze ukusetshenziswa kwamandla ngokwedlulele.
Ukuhlaziya okuzenzakalelayo kanye nokucutshungulwa kwezimo ezihlukahlukene, ukuhlinzeka ngesiteshi esinezinzile nesithembekile senethiwekhi ye-NB-IoT yokudlulisa izinto.
Sekela iphrothokholi ye-UDP, imodi ye-UDP-ZSD esekelwe ku-Mind encapsulation, i-China Telecom CoAP protocol.
Usebenzisa i-Mind's SDK, ukuthuthukiswa kwekhompuyutha engusokhaya kulula, futhi ungakwazi ukusungula isikhungo sakho ngokushesha ngaphandle kwezinhlelo ze-TCP/IP.
Sekela ukucushwa kwepharamitha yendawo nekude kanye nokuthuthukiswa kwe-firmware ekude.
Sekela iphakethe lokubhalisa ngokwezifiso, iphakethe lokushaya kwenhliziyo, iphakethe lesihloko sangokwezifiso, esilungele abasebenzisi ukuthi baqinisekise idatha.
Ukusekelwa okugcwele kwezinhlelo zokusebenza zokucushwa kwezimboni, Iseva ye-OPC (ukwenza ngendlela oyifisayo kuyadingeka), kanye nezimbobo ze-serial ezibonakalayo.
Ukusekelwa okugcwele kwe-Mind IoT Cloud, abasebenzisi abadingi ukuzakhela amaseva abo.
Sekela ukubukwa kwesikhathi sangempela kwewebhu yesimo sokusebenza kwemishini.
Nikeza nge-RS232, isixhumi esibonakalayo sokuxhumana se-RS485, isilinganiso se-baud singakhethwa sisuka ku-1200bps siye ku-38400bps, futhi isiqalo sebhithi/stop bit/parity singakhethwa.
Ukunikezwa kwamandla kanye nembobo ye-serial kusebenzisa ukuvikelwa kwe-TVS anti-surge ukuze kuqinisekiswe ukuzinza nokuthembeka kwezinto zokusebenza.
Sekela ukucushwa kwamahhala kwemiyalo yendawo yokuqoqwa kweskripthi ukuze ubone ukuthi i-DTU iqoqa idatha yensimbi ngaphandle kokungenelela kwekhompyutha yomsingathi.
Sekela amandla ebhethri angaphandle, i-standby eside kumodi yokusetshenziswa kwamandla okuphansi.

Idivayisi isebenzisa amandla aphansi futhi ayikwazi ukwamukela idatha ye-downlink evela esikhungweni sedatha.

I-DTU kufanele ilayishe idatha ngenkuthalo futhi ifake imodi yokuxhuma ngaphambi kokuba isikhungo sithumele idatha.

Ngemuva kokungabikho kokuxhumana kwedatha, i-MDN311 ingena ngokuzenzakalelayo kumodi ye-PSM ukuze igcine ukusetshenziswa kwamandla okulindile okuphansi.

I-MDN311 isekela umsebenzi wokuhlela umbhalo. Abasebenzisi bangakwazi ukwenza ngendlela oyifisayo amafayela ombhalo ngokusebenzisa isofthiwe yokucushwa kwezithombe zemishini, ukuze izinhlelo zokusebenza ezisendaweni zingadingi izilawuli ezengeziwe, futhi zingadingi ukuncika kunkundla yedatha ukuze zikhiphe iziqondiso zokuqoqwa ukuze kuzuzwe ukuxhumana okuqondile nethuluzi. I-MDN311 Qoqa ngokuqondile futhi ngenkuthalo idatha entweni bese uyibika endaweni yesikhulumi.

Ukwenza Ngokwezifiso Ifomethi Yephakethe Ledatha Eguqukayo

Iphakethe lokubhalisa ngokwezifiso:Abasebenzisi bangamisa ngokukhululekile okuqukethwe kwephakethe ledatha elithunyelwe lapho i-MDN311 ixhunywa okokuqala esikhungweni sedatha.

Iphakethe lokushaya kwenhliziyo ngokwezifiso:Abasebenzisi bangamisa ngokukhululekile okuqukethwe kwephakethe lokushaya kwenhliziyo elithunyelwe i-MDN311 esikhungweni sedatha.

Iphakethe likanhlokweni ngokwezifiso:Umsebenzisi angamisa okuqukethwe okuthile ngaphambi kwephakethe ledatha elithunyelwe i-DTU esikhungweni sedatha ukuze kuhlukaniswe uhlobo lwedatha noma isigaba.
