• Te tuku mārama o ngā raraunga raupapa
• 50uA te iti o te whakamahinga hiko
• Te tawhiti whakawhitiwhiti kōrero 3-8km
• Ngā momo whakawhitiwhiti whatunga maha

I ngā momo mahi e toru o runga ake nei, ka taea e MDL311 te tuku me te whiwhi raraunga, ā, ko ngā tawhā kua whakahuatia i runga ake nei he raraunga ine.

He teitei te aro o te hangarau LoRa ki te whiwhi (RSSI) me te ōwehenga tohu-ki-haruru (SNR), me tā mātou hangarau whakarerekētanga me te tango i ngā haruru, he kaha te kaha ārai-whakararuraru o te hua ahokore LoRa, ā, he pumau, he pono hoki te mahi a te hua.

Putanga waea

E rua ngā momo atanga mana e whakaratohia ana e MDL311, e rua ngā momo atanga mana ka taea te whiriwhiri i tētahi hei whakamahi, kāore e taea te hono i te wā kotahi.

Vin+ GND: Ko te whānuitanga ngaohiko hiko o tēnei atanga ko DC 5 ~ 30V;

BAT+ BAT-: Ko te awhe ngaohiko hiko o tēnei atanga he 3.4~4.2V.

Tauranga Rangatū

Kua tohua te RS232 (RXD, TXD, GND) me te atanga 485 ki te papatohu, ā, kotahi anake o aua mea ka taea te whiriwhiri;

Ki te whakamahia i te wā kotahi, me whakarite kia rua ngā tauranga raupapa o te DTU e honoa ana i te wā e whiwhi ana i ngā raraunga tauranga raupapa, ki te kore ka puta he pakanga.

Ko te hua raupapa MDL e whakamahi ana i te PTM ARM iti-mana 32-moka, me te hangarau whakawhitiwhiti RF ahurei o te hangarau Mind, e iti iho ai te au o te hua i te 50uA.

I te 50uA e pau ana te hiko, kei te mahi tonu te pūrere MDL, ā, ka taea e ia te whiwhi me te tuku raraunga i ngā wā katoa, ehara tēnei i te paunga hiko i te wā moe.

*Ka inehia ngā raraunga o runga ake nei i roto i te "aratau matua mana".

Whatunga AD-hoc ngāwari, kaha hoki

Whakawhitiwhiti kōrero pāho

I roto i te whatunga kotahi, ka whakawhitiwhiti kōrero ia taputapu tetahi ki tetahi.

Whakawhitiwhiti kōrero i waenganui i ngā pūwāhi

I roto i te whatunga kotahi, ka taea te whakahaere i te whakawhitiwhiti kōrero i waenga i ngā taputapu e rua.

Whakawhitiwhiti kōrero maha-whakaputa

I roto i te whatunga kotahi, ka taea te whakarite i ngā taputapu kotahi, maha rānei hei rōpū hei whakatutuki i te whakawhitiwhiti kōrero i waenga i ngā rōpū.

*Ka taea te whakakotahi i ngā tikanga whatunga e toru o runga ake nei ki te whatunga kotahi.

*Ka taea e te MDL311 coordination 4G DTU te whakarite i te keti LoRa me te whakatutuki i te tuku raraunga mamao.

Haunga te whakamahi i te raina tauranga raupapa ā-rohe hei whirihora tika i ngā tawhā, ka tautokohia hoki e ngā taputapu Mind LoRa te whirihoranga ahokore o ngā tawhā taputapu mamao.

E ai ki te pikitia i runga ake nei:

Ka honoa te Pūrere A ki te rorohiko mā te taura tauranga raupapa. Mā te whakamahi i te pūmanawa whirihoranga whakairoiro i whakaratohia e tā mātou kamupene, ka taea te whirihora i ngā tawhā o te pūrere ā-rohe a me te tere, ā, ka taea hoki te whirihora i ngā tawhā o te pūrere mamao B e te whatunga ahokore.

*Hei whirihora i ngā tawhā i te aratau ahokore, me whakarite kei roto te pūrere ā-rohe me te pūrere mamao i te whatunga kotahi.
