  • Pob tshab kis ntawm cov ntaub ntawv serial
  • 50uA siv hluav taws xob tsawg
  • 3-8km kev sib txuas lus nrug
  • Ntau hom kev sib txuas lus network

Hauv peb hom kev ua haujlwm saum toj no, MDL311 tuaj yeem xa thiab tau txais cov ntaub ntawv, thiab cov tsis tau hais los saum toj no yog ntsuas cov ntaub ntawv.

LoRa thev naus laus zis muaj qhov siab tau txais txiaj ntsig zoo (RSSI) thiab teeb liab-rau- suab nrov piv (SNR), ua ke nrog peb cov kev hloov kho thiab kev siv tshuab demodulation, LoRa wireless cov khoom muaj zog tiv thaiv kev cuam tshuam thiab ruaj khov thiab txhim khu kev qha khoom.

Chaw nres nkoj

MDL311 muab ob hom fais fab sib txuas, ob hom fais fab sib txuas tsuas tuaj yeem xaiv ib qho los siv, tsis tuaj yeem txuas rau tib lub sijhawm.

Vin + GND: Lub hwj chim mov voltage ntau ntawm no interface yog DC 5 ~ 30V;

BAT + BAT-: Lub zog hluav taws xob ntau ntawm qhov kev sib txuas no yog 3.4 ~ 4.2V.

Serial Chaw nres nkoj

RS232 (RXD, TXD, GND) thiab 485 interface raug cim rau ntawm lub vaj huam sib luag, thiab tsuas yog ib qho ntawm lawv tuaj yeem xaiv tau;

Yog tias nws siv tib lub sijhawm, nws yog qhov tsim nyog los xyuas kom meej tias ob qhov chaw nres nkoj ntawm DTU yog staggered nyob rau hauv lub sij hawm ntawm recei serial chaw nres nkoj cov ntaub ntawv, txwv tsis pub yuav muaj teeb meem.

MDL series khoom siv 32-ntsis ARM tsawg-power CPU, thiab cov cim RF kev sib txuas lus ntawm lub siab thev naus laus zis, uas ua rau cov khoom muag tam sim no tsawg dua 50uA.

Ntawm 50uA kev siv hluav taws xob, MDL ntaus ntawv tseem nyob hauv lub xeev ua haujlwm thiab tuaj yeem tau txais thiab xa cov ntaub ntawv txhua lub sijhawm, uas tsis yog lub zog siv hauv kev pw tsaug zog.

* Qhov saum toj no tag nrho cov ntaub ntawv yog ntsuas nyob rau hauv "lub zog tseem ceeb hom".

Yooj yim thiab muaj zog AD-hoc network

Tshaj tawm kev sib txuas lus

Hauv tib lub network, txhua lub cuab yeej sib txuas lus nrog ib leeg.

Point-point kev sib txuas lus

Hauv tib lub network, kev sib txuas lus taw tes ntawm ob lub cuab yeej tuaj yeem ua tiav.

Multicast kev sib txuas lus

Hauv tib lub network, ib leeg lossis ntau yam khoom siv tuaj yeem tsim ua ib pawg kom paub txog kev sib txuas lus ntawm pawg

* Peb txoj kev sib txuas lus saum toj no tuaj yeem ua ke hauv tib lub network.

* MDL311 kev sib koom tes 4G DTU tuaj yeem teeb tsa LoRa rooj vag yooj yim thiab paub txog cov ntaub ntawv xa mus rau cov chaw taws teeb.

Ntxiv nrog rau kev siv cov kab hauv zos serial chaw nres nkoj los teeb tsa qhov tsis ncaj ncees lawm, Cov cuab yeej Mind LoRa kuj tseem txhawb nqa wireless configuration ntawm tej thaj chaw deb ntaus ntawv tsis.

Raws li pom hauv daim duab saum toj no:

Ntaus A txuas nrog lub computer los ntawm serial chaw nres nkoj cable. Siv cov graphical configuration software muab los ntawm peb lub tuam txhab, cov tsis muaj nyob rau hauv lub zos ntaus ntawv a yuav configured yooj yim thiab sai, thiab cov tsis muaj tej thaj chaw deb ntaus B kuj yuav configured los ntawm lub wireless network.

* Txhawm rau teeb tsa qhov tsis sib xws hauv hom wireless, nws yog ib qho tsim nyog los xyuas kom meej tias cov cuab yeej hauv zos thiab cov cuab yeej siv tau nyob hauv tib lub network.
