• Transparent transparent yeserial data
• 50uA yakaderera simba rekushandisa
• 3-8km kutaurirana kure
• Multiple network communication modes

Mune matatu ari pamusoro ekushanda modes, MDL311 inogona kutumira uye kugamuchira data, uye maparameter ataurwa pamusoro anoyerwa data.

LoRa tekinoroji ine yakakwira recei senitivity (RSSI) uye chiratidzo-kune-ruzha ratio (SNR), yakasanganiswa neyedu yekumisikidza modulation uye demodulation tekinoroji, LoRa isina waya chigadzirwa chine yakasimba anti-kupindira kugona uye yakagadzikana uye yakavimbika chigadzirwa kuita.

Wiring port

MDL311 inopa marudzi maviri emagetsi interface, maviri emhando yemagetsi interface anogona chete kusarudza imwe yekushandisa, haigone kubatana panguva imwe chete.

Vin+ GND: Iyo magetsi emagetsi emhando yeiyi interface ndeye DC 5 ~ 30V;

BAT + BAT-: Iyo magetsi emagetsi emhando yeiyi interface ndeye 3.4 ~ 4.2V.

Serial Port

RS232 (RXD, TXD, GND) uye 485 interface yakanyorwa pane panhizha, uye imwe chete yadzo inogona kusarudzwa;

Kana ikashandiswa panguva imwe chete, zvinodikanwa kuve nechokwadi kuti maviri serial ports eDTU akazununguka munguva yekugamuchira serial port data, zvikasadaro pachave nekukakavadzana.

MDL yakatevedzana chigadzirwa inotora 32-bit ARM yakaderera-simba CPU, uye yakasarudzika RF yekutaurirana tekinoroji yeMind tekinoroji, iyo inoita kuti chigadzirwa chakamira chiripo chiri pasi pe50uA.

Pa50uA simba rekushandisa, MDL mudziyo ichiri kushanda uye inogona kugamuchira uye kutumira data chero nguva, iyo isiri iyo simba rekushandisa pasi pekurara.

*Iyo iri pamusoro pese data inoyerwa mu "simba rekutanga maitiro".

Flexible uye ine simba AD-hoc network

Nhepfenyuro yekukurukurirana

Mune imwechete network, mudziyo wega wega unotaurirana nemumwe.

Kutaurirana-pfungwa

Mune imwecheteyo network, point-point kutaurirana pakati pezvipi zvese zviviri zvinogona kuitika.

Multicast kutaurirana

Munetiweki imwe chete kana akawanda maturusi anogona kusetwa seboka kuti aone kutaurirana pakati pemapoka

*Idzi dziri pamusoro nzira nhatu dzekuti network dzinogona kusanganiswa mune imwecheteyo network.

* MDL311 coordination 4G DTU inogona kuseta nyore LoRa gedhi uye kuona kure kure kuendesa data.

Pamusoro pekushandisa yemuno serial port mutsara kugadzirisa ma paramita zvakananga, Mind LoRa michina inotsigirawo isina waya yekumisikidzwa kweiyo kure mudziyo paramita.

Sezvinoratidzwa pamufananidzo uri pamusoro:

Chishandiso A chakabatana pakombuta kuburikidza neserial port tambo.Uchishandisa iyo graphical kumisikidza software yakapihwa nekambani yedu, ma parameter echishandiso chemuno a anogona kugadzirwa zviri nyore uye nekukurumidza, uye maparamita echinhu chiri kure B anogonawo kugadzirwa newaya isina waya.

*Kugadzirisa maparamendi mune isina waya modhi, zvinodikanwa kuve nechokwadi chekuti mudziyo wemuno uye mudziyo uri kure uri mune imwecheteyo network.
