2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:28

Kev sib txuas: USB - Serial

Xav tau: Chrome Browser

Xav tau: 1 X Arduino Mega

Xav tau: 1 X GPS

Xav tau: 1 X SD daim npav

Xav tau: 2 X LoRa Modem RF1276

Muaj nuj nqi: Arduino Xa GPS tus nqi mus rau lub hauv paus loj-Lub hauv paus tseem ceeb khaws cov ntaub ntawv hauv Dataino Server Lora Module: Ultra ntev ntau RF1276 los ntawm APPCONWIRELESS LoRa yog qhov tshiab, ntiag tug thiab nthuav dav-spectrum tes taws los piav txheej txheem uas tso cai xa cov ntaub ntawv ntawm cov ntaub ntawv qis heev-tus nqi mus rau qhov kawg ntev ntau yam. Cov ntaub ntawv qis-tus nqi (nqes mus rau ob peb bytes ib pliag) thiab LoRa kev hloov pauv ua rau tus neeg txais kev nkag siab tsawg heev, txhais tau tias hauv qhov kev ntsuas no txhais tau ntau dua 10km.

Kauj Ruam 1: Tsim Chaw Nres Tsheb

Khoos phis tawj dav siv internet txuas thiab LoRa modem txuas rau hauv USB chaw nres nkoj.

Arduino Tsheb Khoom ·

Lub thawv ntsuas

Anduino Mega txuas nrog ntu 2 rau GPS tus txais, thiab Serial 1 rau LoRa modem. Ib daim npav SD siv rau khaws cov ntaub ntawv.

Kauj Ruam 2: Thawj Xeem

· 10.6 Km ntawm txoj hauv kev hla cov nroog hauv nroog, chav tso duab thiab raws ntug dej hiav txwv ua nrog lub voj

Qhov sib piv ntawm kev txais tos /kis tau ntawm 321 /500TX taw tes

RX point ua

Kauj Ruam 3: Tsim Kev Sib Tham

1 - Teeb tsa txoj haujlwm tshiab LoRa

Nias lub cim cog los qhib qhov project teeb tsa

Kauj ruam 4: Ntxiv Ntsuas

2) Qhib lub ntsuas qhov ntsuas.

· 3) Scroll rau GPS.

· 4) Ntxiv ib qho rau ntawm lub rooj.

Kauj Ruam 5: Luag Gauge GPS thiab Ntxiv OpenStreetMap

· 5) Ntxiv OpenStreetMap daim ntawv qhia rau lub rooj

Rub tus tivthaiv GPS ntawm daim duab qhia chaw, OpenStreet daim ntawv qhia tau tsim.

Tsim qhov Interface

· 6) Hloov daim ntawv qhia tshiab

Hloov daim ntawv qhia sijhawm tshiab los ntawm 5000 txog 10000

Kauj Ruam 6: Luag GPS Gauge thiab Ntxiv Cov Lus Teev Npe

· 7) Ntxiv rau Table Log gauge.

Los ntawm kev rub lub ntsuas cua saum lub GPS icon lub rooj yog tsim cov lus ntsuas lub rooj

· 8) Hloov cov lus teev rooj tshiab. Hloov daim ntawv qhia sijhawm tshiab los ntawm 5000 txog 10000

Kho qhov chaw ntawm cov ntsuas

· 9) Luag cov ntsuas ntsuas kho qhov chaw ntawm cov ntsuas los ntawm kev rub lawv hla lub vijtsam.

· 10) Txuag qhov project

Kauj ruam 7: Tau txais Code

10) Qhib cov cai ntim

Khawm nyob rau sab saum toj txoj cai khawm, xaiv tag nrho thiab luam cov cai hauv paus.

Kauj Ruam 8: Arduino IDE

· 11) Muab tshuaj txhuam tus lej ntawm Arduino IDE

· 12) Kho qhov chaws Ntxiv kab no hauv cov lus txhais

Kauj ruam 9: Coding Paub meej

Ntxiv kab no hauv lub ntsiab lus
