Piav qhia:

IoT Node (A) yog ib qho ntawm Docker Pi series qauv.

IOT Node (A) = GPS/BDS + GSM + Lora.

I2C tswj ncaj qha Lora, xa thiab txais cov ntaub ntawv, tswj GSM/GPS/BDS module los ntawm SC16IS752, lub hauv paus tsuas xav tau kev txhawb nqa I2C.

Txhawb Raspberry Pi thiab lwm yam khoom zoo sib xws.

Nta:

· Docker Pi Series

· Programmable

· Tswj ncaj qha (tsis muaj phiaj xwm)

· Txuas ntxiv GPIO Pins

· Txhawb GPS/BDS

· Txhawb GSM

· Txhawb Lora

· Ua Stack nrog lwm pawg pawg pawg

· Ywj siab ntawm lub khoos phis tawj mainboard (xav tau kev txhawb nqa I2C)

Kev Xeem Ua Haujlwm Tau Zoo

Tsis tsuas yog txhawb nqa cov phiaj xwm txhim kho hauv qab no, lwm cov laug cam kev txhim kho tuaj yeem sib haum yog tias lawv muaj I2C cov khoom siv sib txuas. (Nco tseg: qee qhov kev hloov pauv software yuav tsum tau ua)

Raspberry Pi series (4B/3B+/3B/2B)

Khoom siv

1 x Raspberry Pi 4B /3B+ /3B board

1 x DockerPi IoT Node (A) Hat board

1 x 5V@3A Fais fab mov

1 x 16GB chav kawm 10 TF daim npav (32GB yuav zoo)

Kauj ruam 1: Kev qhia tshwj xeeb

GPRS ntu:

· 1. Tsawg zog siv, tos pw tam sim no <1mA

· 2. Txhawb GSM/GPRS plaub zaus, suav nrog 850, 900, 1800, 1900MHZ;

· 3. GPRS Class 10;

· 4. Txhawb kev pabcuam GPRS cov ntaub ntawv, cov ntaub ntawv siab tshaj plaws, rub tawm 85.6Kbps, upload 42.8Kbps;

· 5. Txhawb tus qauv GSM07.07, 07.05 AT cov lus txib, thiab nkag mus rau qhov chaw nres nkoj txuas los ntawm I2C interface hloov dua siab tshiab.

· 6. AT cov lus txib txhawb tus qauv AT thiab TCP/IP hais kom ua chaw nres nkoj

GPS ntu

· 1. Txhawb BDS/GPS sib koom ua haujlwm

· 2. Txhawb A-GPS, A-BDS

· 3. Txhawb tus qauv SIM daim npav

LORA ntu ：

· 1. Kev xa mus deb: 500 Meters (RF tsis: 0x50 @ Tuam Tshoj Lub Nroog)

· 2. Txhawb FSK, GFSK, MSK, GMSK, LoRaTM thiab OOK txoj kev hloov kho

· 3. Ultra -high receiver rhiab heev li tsawg li -141 dBm

· 4. Txhawb kev pom ua ntej

· 5. Pob ntawv cav nrog CRC, mus txog 256 bytes

· 6. LORA cov cim qhia kev xa xov

· 7. Yooj Yim TX/RX los ntawm Docker Pi

Kauj Ruam 2: Pob suav nrog

Pob Muaj

· 1 x IoT Node (A) Pawg Thawj Coj

· 1 x Cov lus qhia

· 4 x M2.5*12 + 6 Tooj tooj liab

· 4 x M2.5*6 Txiv Ntseej

· 4 x M2.5*6 Ib nrab taub hau ntsia hlau

· 1 x 2.4GHz PCB Kav hlau txais xov

· 1 x GPS/BDS Siab Tau GPS Ua-nyob rau hauv Ceramic Active Antenna

Kauj Ruam 3: Cov Lus Qhia Paub ：

A9G Qauv

· A9G module muaj ob qhov chaw nres nkoj.

· Siv I2C UART choj rau kev sib txuas lus.

Kauj Ruam 4: Sau Npe Daim Ntawv Qhia

nov yog daim ntawv qhia chaw thiab piav qhia txog kev sau npe.

0x01 - 0x10 Sau Xwb.

0x11 - 0x20 Nyeem Xwb.

Nws tau pom zoo kom khaws lub neej ntawd tshwj tsis yog koj paub lub ntsiab lus ntawm LORA qhov ntsuas.

· L_SET (Tsuas Xeem)

1. Sau 1 txhawm rau teeb tsa tsis los ntawm 0x22 rau LORA Module.

2. Sau 0 tsis cuam tshuam

· G_RESET (Tsuas Xeem)

1. Sau 1 kom rov pib dua A9G Module

2. Sau 0 tsis cuam tshuam

· L_RXNE (Nyeem & Sau)

1. Sau 1 qhov ua rau yuam kev

2. Sau 0 kom pom tseeb

3. Nyeem 1 txhais tau tias tau txais cov ntaub ntawv, thov tau txais cov ntaub ntawv los ntawm kev sau npe 0x11 - 0x20.

4. Nyeem 0 txhais tias tsis muaj cov ntaub ntawv tam sim no.

· L_SET (Tsuas Xeem)

1. Sau 1 kom xa cov ntaub ntawv, thov sau cov ntaub ntawv hauv npe 0x01 - 0x10 ua ntej xa.

2. Sau 0 tsis cuam tshuam
