• Ugqithiso olungafihliyo lwedatha yothotho
• 50uA ukusetyenziswa kwamandla aphantsi
• 3-8km umgama wonxibelelwano
• Iindlela zonxibelelwano lwenethiwekhi ezininzi

Kwiindlela ezintathu zokusebenza ezingentla, i-MDL311 ingathumela kwaye ifumane idatha, kwaye iiparitha ezikhankanywe ngasentla ziyidatha elinganisiweyo.

Itekhnoloji ye-LoRa inovakalelo oluphezulu lwe-recei (RSSI) kunye ne-signal-to-noise ratio (SNR), idityaniswe ne-modulation yethu yobunini kunye ne-demodulation technology, imveliso engenazingcingo ye-LoRa inamandla okuchasa ukuphazamiseka kunye nokusebenza kwemveliso okuzinzileyo nokuthembekileyo.

Izibuko locingo

I-MDL311 ibonelela ngeentlobo ezimbini zojongano lwamandla, iindidi ezimbini zojongano lwamandla zinokukhetha enye kuphela enokusetyenziswa, ayinakudityaniswa ngaxeshanye.

Vin+ GND: Uluhlu lwamandla ombane wolu jongano yiDC 5 ~ 30V;

I-BAT + BAT-: Uluhlu lwamandla ombane wolu jongano luyi-3.4 ~ 4.2V.

Uthotho lwezibuko

I-RS232 (i-RXD, i-TXD, i-GND) kunye ne-interface ye-485 iphawulwe kwiphaneli, kwaye enye kuphela kubo inokukhethwa;

Ukuba isetyenziswe ngexesha elifanayo, kuyimfuneko ukuqinisekisa ukuba izibuko ezimbini ze-serial ze-DTU ziphazamisekile ngexesha ledatha ye-recei ye-serial port, ngaphandle koko kuya kubakho iingxabano.

Imveliso yochungechunge lwe-MDL ithatha i-32-bit ye-ARM enamandla aphantsi-amandla e-CPU, kunye ne-RF eyodwa yetekhnoloji yonxibelelwano yetekhnoloji yeNgqondo, eyenza imveliso yokulinda yangoku ingaphantsi kwe-50uA.

Kwi-50uA yokusetyenziswa kwamandla, isixhobo se-MDL sisasebenza kwaye sinokufumana kwaye sithumele idatha nanini na, okungekho ukusetyenziswa kwamandla phantsi kokulala.

*Le datha ingentla ilinganiswa "kwimowudi yokubaluleka kwamandla".

Inethiwekhi ye-AD-hoc eguquguqukayo nenamandla

Unxibelelwano losasazo

Kwinethiwekhi efanayo, isixhobo ngasinye sinxibelelana esinye.

Inqaku lonxibelelwano

Kwinethiwekhi efanayo, unxibelelwano lwengongoma phakathi kwazo naziphi na izixhobo ezibini lunokuphunyezwa.

Unxibelelwano oluninzi

Kwinethiwekhi efanayo, isixhobo esinye okanye ezininzi zinokusetwa njengeqela ukuqonda unxibelelwano phakathi kwamaqela

*Ezi ndlela zintathu zothungelwano zingadityaniswa kuthungelwano olunye.

*Ulungelelwaniso lwe-MDL311 4G DTU lunokuseta ngokulula isango le-LoRa kwaye iqonde ukuhanjiswa kwedatha ekude.

Ukongeza ekusebenziseni umgca we-serial port wendawo ukuqwalasela iiparamitha ngokuthe ngqo, izixhobo ze-Mind LoRa zikwaxhasa uqwalaselo olungenacingo lweeparamitha zesixhobo esikude.

Njengoko kubonisiwe kulo mfanekiso ungasentla:

Isixhobo A siqhagamshelwe kwikhompyuter ngentambo yesiriyali yezibuko. Ngokusebenzisa isoftware yoqwalaselo lwegraphical ebonelelwe yinkampani yethu, iiparamitha zesixhobo sendawo a zinokuqwalaselwe ngokufanelekileyo nangokukhawuleza, kwaye iiparamitha zesixhobo esikude B zinokumiselwa yinethiwekhi engenazingcingo.

*Ukumisela iiparamitha kwimowudi engenazingcingo, kuyafuneka ukuqinisekisa ukuba isixhobo sasekhaya kunye nesixhobo esikude sikunethiwekhi efanayo.
