Kwiindlela ezintathu zokusebenza ezingentla, i-MDLR311 ingathumela kwaye ifumane idatha, kwaye iiparamitha 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-MDLR311 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 zeI-RTUziyahluzwa ngexesha lothotho lwedatha yezibuko, kungenjalo 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-MDLR311 4G RTU luseta 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.
