• Kutapurirana pachena kwedata rakatevedzana
• 50uA kushandiswa kwesimba kushoma
• Nharaunda yekutaurirana ye3-8km
• Nzira dzakawanda dzekutaurirana netiweki

Munzira nhatu dziri pamusoro apa dzekushanda, MDL311 inogona kutumira nekugamuchira data, uye ma parameter ataurwa pamusoro apa idata rakayerwa.

Tekinoroji yeLoRa ine high receiving sensitivity (RSSI) uye signal-to-noise ratio (SNR), pamwe chete ne proprietary modulation and demodulation technology yedu, LoRa wireless product ine simba rakasimba rekudzivirira kukanganiswa uye kushanda kwakasimba uye kwakavimbika kwechigadzirwa.

Chiteshi chekubatanidza waya

MDL311 inopa mhando mbiri dzesimba rekubatanidza, mhando mbiri dzesimba rekubatanidza dzinogona kusarudza imwe chete yekushandisa, uye hadzigoni kubatanidzwa panguva imwe chete.

Vin+ GND: Huremu hwemagetsi ekushandisa painterface iyi iDC 5 ~ 30V;

BAT+ BAT-: Huremu hwemagetsi ekushandisa painterface iyi i3.4~4.2V.

Chiteshi cheSerial

RS232 (RXD, TXD, GND) uye 485 interface zvakaiswa papaneru, uye chimwe chete chazvo chinogona kusarudzwa;

Kana ikashandiswa panguva imwe chete, zvakakosha kuve nechokwadi chekuti maport maviri eDTU akarongwa panguva yedata receiver serial port, zvikasadaro pachava nekusawirirana.

Chigadzirwa cheMDL series chinoshandisa 32-bit ARM low-power CPU, uye tekinoroji yekutaurirana yeRF yakasarudzika yeMind, izvo zvinoita kuti standby current yechigadzirwa ive pasi pe50uA.

Pakushandisa simba re50uA, MDL mudziyo uchiri kushanda uye unogona kugamuchira nekutumira data chero nguva, izvo zvisiri simba rinoshandiswa panguva yekurara.

*Data rese riri pamusoro apa rinoyerwa mu "power priority mode".

Network yeAD-hoc inochinjika uye ine simba

Kutaurirana kwenhepfenyuro

Mune network imwe chete, mudziyo wega wega unotaurirana.

Kutaurirana pakati pezvinhu zviviri

Munetwork imwe chete, kutaurirana pakati pemidziyo miviri kunogona kuitwa.

Kutaurirana kwemavhidhiyo akawanda

Mune network imwe chete, zvishandiso chimwe chete kana zvakawanda zvinogona kuiswa seboka kuti zviite kutaurirana pakati pemapoka

*Nzira nhatu dziri pamusoro apa dzekubatanidza network dzinogona kubatanidzwa mune imwe network.

*MDL311 coordination 4G DTU inogona nyore nyore kugadzirisa LoRa gateway uye kuita kuti data ritapurirwe kure.

Pamusoro pekushandisa mutsetse wechiteshi chemuno kugadzirisa maparamita zvakananga, michina yeMind LoRa inotsigirawo magadzirirwo asina waya emaparamita emudziyo uri kure.

Sezvakaratidzwa pamufananidzo uri pamusoro apa:

Mudziyo A wakabatana nekombuta kuburikidza netambo yechiteshi cheserial. Uchishandisa software yekugadzirisa mifananidzo yakapihwa nekambani yedu, maparamita emudziyo wekombuta a anogona kugadziriswa zviri nyore uye nekukurumidza, uye maparamita emudziyo wekombuta B anogonawo kugadziriswa nenetwork isina waya.

*Kuti ugadzire ma parameters mu wireless mode, zvakakosha kuve nechokwadi chekuti mudziyo wepanzvimbo nemudziyo uri kure zviri mu network imwe chete.
