• Ukudluliselwa kwedatha ecacileyo
• Ukusetyenziswa kwamandla okuphantsi kwe-50uA
• Umgama wonxibelelwano we-3-8km
• Iindlela ezininzi zonxibelelwano lwenethiwekhi

Kwiindlela ezintathu zokusebenza ezingentla, i-MDL311 inokuthumela kwaye ifumane idatha, kwaye iiparameter ezikhankanyiweyo apha ngasentla yidatha elinganisiweyo.

Itekhnoloji yeLoRa inovakalelo oluphezulu lokufumana ulwazi (i-RSSI) kunye nomlinganiselo wesignali-kwingxolo (i-SNR), kunye netekhnoloji yethu yokuguqula kunye nokunciphisa ulwazi, imveliso engenazingcingo yeLoRa inamandla okulwa nokuphazamiseka kunye nokusebenza kwemveliso okuzinzileyo nokuthembekileyo.

Izibuko locingo

I-MDL311 ibonelela ngeentlobo ezimbini zojongano lwamandla, iintlobo ezimbini zojongano lwamandla zinokukhetha enye kuphela ukuba ziyisebenzise, ​​azinakuqhagamshelwa ngaxeshanye.

I-Vin+ GND: Uluhlu lwevolthi yombane yolu jongano yi-DC 5 ~ 30V;

I-BAT+ BAT-: Uluhlu lwevolthi yombane yolu jongano yi-3.4~4.2V.

Izibuko le-Serial

I-RS232 (RXD, TXD, GND) kunye ne-485 interface ziphawulwe kwiphaneli, kwaye inye kuphela kuzo enokukhetha;

Ukuba isetyenziswa ngaxeshanye, kuyimfuneko ukuqinisekisa ukuba iiport ezimbini ze-serial ze-DTU zixananazisiwe ngexesha ledatha ye-receiving serial port, kungenjalo kuya kubakho iingxabano.

Imveliso yochungechunge lwe-MDL isebenzisa i-CPU enamandla aphantsi angama-32-bit ARM, kunye netekhnoloji yonxibelelwano ye-RF ekhethekileyo yetekhnoloji ye-Mind, eyenza ukuba umbane wemveliso okwi-standby ube ngaphantsi kwe-50uA.

Xa isetyenziswa ngamandla angama-50uA, isixhobo se-MDL sisasebenza kwaye sinokufumana kwaye sithumele idatha nangaliphi na ixesha, into engeyiyo ukusetyenziswa kwamandla xa ulele.

*Idatha engentla yonke ilinganiswa kwi-"power priority mode".

Inethiwekhi ye-AD-hoc eguquguqukayo nenamandla

Unxibelelwano losasazo

Kwinethiwekhi efanayo, isixhobo ngasinye sinxibelelana.

Unxibelelwano olunenqaku

Kwinethiwekhi efanayo, unxibelelwano oluphambili phakathi kwezixhobo ezibini lunokuphunyezwa.

Unxibelelwano olusebenzisa izixhobo ezininzi

Kwinethiwekhi enye, izixhobo esinye okanye ezininzi zinokusetwa njengeqela ukuze kufezekiswe unxibelelwano phakathi kwamaqela.

*Ezi ndlela zintathu zokunxibelelana zingadityaniswa kwinethiwekhi enye.

*Unxibelelwano lwe-MDL311 4G DTU lunokuseta isango le-LoRa ngokulula kwaye lukwazi ukudlulisa idatha ekude.

Ukongeza ekusebenziseni umgca wezibuko lothotho lwasekhaya ukumisela ngokuthe ngqo iiparameter, izixhobo zeMind LoRa zikwaxhasa uqwalaselo olungenazingcingo lweeparameter zesixhobo esikude.

Njengoko kubonisiwe kumfanekiso ongentla:

Isixhobo A siqhagamshelwe kwikhompyutha ngentambo yezibuko ezilandelelanayo. Sisebenzisa isoftware yoqwalaselo lwemizobo ebonelelwe yinkampani yethu, iiparameter zesixhobo sendawo u-a zinokucwangciswa ngokulula nangokukhawuleza, kwaye iiparameter zesixhobo esikude u-B nazo zinokucwangciswa yinethiwekhi engenazingcingo.

*Ukuze ulungiselele iiparameters kwimo engenazingcingo, kuyimfuneko ukuqinisekisa ukuba isixhobo sendawo kunye nesixhobo esikude zikwinethiwekhi efanayo.
