I-LSN50v2-D20 v1.0: Khulula

Uyisebenzisa njani iLSN50v2-D20

Ingaba isebenza kanjani
I-LSN50v2-D20 isebenza njenge-LoRaWAN OTAA Class A end node. I-LSN50v2-D20 nganye ithunyelwa kunye neseti ekhethekileyo yehlabathi jikelele ye-OTAA kunye nezitshixo ze-ABP. Umsebenzisi ufuna ukufaka iOTAA okanye izitshixo ze-ABP kwiseva yenethiwekhi ye-LoRaWAN ukubhalisa. Vula i-enclosure kunye namandla kwi-LSN50v2-D20, iya kujoyina inethiwekhi ye-LoRaWAN kwaye iqale ukudlulisa idatha. Ixesha elimiselweyo kwi-uplink nganye yimizuzu engama-20.

Isikhokelo esikhawulezayo sokuqhagamshela kwiseva ye-LoRaWAN (OTAA)
Nantsi i-example ngendlela yokujoyina Iseva ye-TTN yeLoRaWAN Ngezantsi isakhiwo sothungelwano, kule demo siyisebenzisayo IDLOS8 njengesango leLoRaWAN.
LSN50v2-D20 kwiNethiwekhi yeLoRaWAN.

I-DLOS8 sele isetiwe ukuqhagamshela kuyo TTN . Yintoni enye ekufuneka siyenzile kukubhalisa i-LSN50V2-D20 kwi-TTN:
Inyathelo loku-1: Yenza isixhobo kwi-TTN kunye nezitshixo ze-OTA ezivela kwi-LSN50V2-D20.
Nganye i-LSN50V2-D20 ithunyelwa ngesincamathelisi esinesixhobo esihlala sihleli se-EUI njengalapha ngezantsi:

Faka ezi zitshixo kwi-portal yeseva ye-LoRaWAN. Apha ngezantsi kukho umfanekiso weskrini we-TTN:

Yongeza i-APP EUI kwisicelo

Yongeza i-APP KEY kunye ne-DEV EUI

Inyathelo loku-2: Amandla kwi-LSN50V2-D20

Inyathelo lesi-3: I-LSN50V2-D20 iya kujoyina ngokuzenzekela kuthungelwano lwe-TTN ngokhuseleko lwe-LoRaWAN yi-DLOS8. Emva kokujoyina impumelelo, i-LSN50V2-D20 iya kuqalisa ukunyusa ixabiso lobushushu kwiseva.

Misela i-Alarm Threshold:

• NGOMYALELO:

Seta zonke iiProbes:

AT+18ALARM=min,ubuninzi

• Xa umzuzu=0, kunye nobukhulu≠0, iAlarm iqalisa xa iphezulu kunobuninzi
• Xa umz≠0, kunye nobukhulu=0, iAlarm iqalisa xa ingaphantsi kunomzuzu
• Xa min≠0 kunye nobukhulu ≠0, iAlarm ivula xa iphezulu kunobuninzi okanye ngaphantsi kunomzuzu

Example:
AT+18ALARM=-10,30 // I-alamu xa <-10 okanye ngaphezulu kwe-30.

• Ikhonkco lokukhuphela intlawulo:
  0x(0B F6 1E) // Iyafana ne AT+18ALARM=-10,30
  (qaphela: 0x1E= 30, 0xF6 ithetha: 0xF6-0x100 = -10)

Cwangcisa uPhando olwahlukileyo:
AT+18ALARM=min,max,index Index:

• 1: Ubushushu Bomvu
• 2: Ubushushu obumhlophe
• 3: Ubushushu Mnyama

Example:
AT+18ALARM=-10,30,1 // I-alamu xa iqondo lobushushu libomvu <-10 okanye ngaphezulu kwe-30.

• Ikhonkco lokukhuphela intlawulo:

Ibhetri & indlela yokubuyisela

Uhlobo Lwebhetri
I-LSN50V2-D2X ixhotyiswe ngebhetri ye-8500mAH ER26500 Li-SOCI2. Ibhetri yibhetri engaphinde itshajwe kwaye inezinga eliphantsi lokukhupha elijoliswe kwiminyaka eyi-8 ~ 10 yokusetyenziswa. Olu hlobo lwebhetri luqhele ukusetyenziswa kwithagethi ye-IoT yokusebenza ixesha elide, njengemitha yamanzi.
Igophe lokukhupha alikho mgca ngoko ke awukwazi ukusebenzisa ipesentitage ukubonisa inqanaba lebhetri. Ngezantsi ukusebenza kwebhetri.

Ukukhutshwa okuqhelekileyo profile ku +20 C (Ixabiso eliqhelekileyo)

Ubuncinci boMsebenzi VoltagI-e ye-LSN50V2-D2X:
LSN50V2-D2X: 2.45v ~ 3.6v

Buyisela ibhetri
Nayiphi na ibhetri enoluhlu lwe-2.45 ~ 3.6v inokuba yinto yokutshintsha. Sicebisa ukuba usebenzise i-Li-SOCl2 Ibhetri.
Kwaye qinisekisa ukuba izikhonkwane ezilungileyo nezingalunganga ziyahambelana.
Uhlalutyo lokuSetyenziswa kwamandla
Imveliso enikwe amandla ngebhetri yeDragino zonke ziqhutywa kwimowudi yaMandla aPhantsi. Sinesixhobo sokubala sebhetri esihlaziyiweyo esisekelwe kumlinganiselo wesixhobo sokwenyani. Umsebenzisi unokusebenzisa le calculator ukujonga ubomi bebhetri kwaye abale ubomi bebhetri ukuba ufuna ukusebenzisa ikhefu lokuhambisa elahlukileyo.

Umyalelo wokusetyenziswa ngolu hlobo lulandelayo:

• Ubungakanani bebhetri,
• Ibhetri yeLithium-Thionyl Chloride ishiti yedatha, Itekhnoloji
• Lithium-ion Battery-Capacitor idatha, Tech Spec

Inqaku leBhetri
Ibhetri ye-Li-SICO yenzelwe usetyenziso oluncinci lwangoku / ixesha elide. Akulunganga ukusebenzisa indlela yangoku ephezulu, yexesha elifutshane yokuhambisa. Elona xesha lincinci elicetyiswayo lokusetyenziswa kweli bhetri yimizuzu emi-5. Ukuba usebenzisa ixesha elifutshane ukusasaza i-LoRa, ngoko ke ubomi bebhetri bunokwehliswa.

Buyisela ibhetri
Unokutshintsha ibhetri kwi-LSN50V2-D2X. Uhlobo lwebhetri alukhawulelwanga nje ukuba imveliso iphakathi kwe-3v ukuya kwi-3.6v. Kwibhodi ephambili, kukho i-diode (D1) phakathi kwebhetri kunye nesekethe enkulu. Ukuba ufuna ukusebenzisa ibhetri engaphantsi kwe-3.3v, nceda ususe i-D1 kwaye unqumle iipads zayo ezimbini ukuze kungabikho volthi.tage yehla phakathi kwebhetri kunye nebhodi engundoqo.
Ipakethi yebhetri engagqibekanga ye-LSN50V2-D2X ibandakanya i-ER26500 kunye ne-super capacitor. Ukuba umsebenzisi akakwazi ukufumana le pakhi ekuhlaleni, banokufumana i-ER26500 okanye ukulingana, okuya kusebenza kwakhona kwiimeko ezininzi. I-SPC inokwandisa ubomi bebhetri ngokusetyenziswa rhoqo rhoqo (ixesha lohlaziyo elingaphantsi kwemizuzu emi-5)
