2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29

Raws li tus tub ntxhais kawm Kuv feem ntau tsis nco nqa kuv phau ntawv thiab lwm yam ntaub ntawv mus rau chav kawm. Kuv tau sim siv cov txheej txheem online tab sis txawm hais tias kuv yuav tas li tso cov khoom ntawm kuv lub rooj.

Cov tshuaj kuv tuaj nrog yog lub hnab ev ntse.

Hauv cov lus qhia no kuv yuav qhia koj yuav ua li cas tsim lub hnab ev ntawv nrog NFC-cov ntsiab lus taug qab thiab GPS nrhiav kab ke. Lub hnab ev ntawv muab tswv yim hla lub 12x LED Adafruit Neopixel.

Lub hnab ev ntawv txuas nrog Flask lub vev xaib uas koj tuaj yeem pom dab tsi hauv koj lub hnab ev ntawv, ntxiv cov ntaub ntawv, thiab tsim cov haujlwm.

Kauj Ruam 1: Qhov Chaw thiab Cov Cuab Yeej

Nov yog qhov koj yuav xav tsim Back Pi, qhov no yog txhua yam kuv tau siv yam tsis muaj cov cuab yeej yooj yim zoo li rab riam.

• PN532 NFC/RFID maub los breakout board - v1.6
• NeoPixel Nplhaib - 12 x 5050 RGBW LEDs w/ Cov Tsav Tsheb Sib Koom
• Adafruit Ultimate GPS Breakout - 66 channel w/10 Hz hloov tshiab - Version 3
• GPS Kav hlau txais xov - Tus kav hlau txais xov sab nraud - 3-5V 28dB 5 Meter SMA
• SMA rau uFL/u. FL/IPX/IPEX RF Adapter Kabel (rau GPS txais)
• USB rau TTL Serial Cable - Debug / Console Cable rau Raspberry Pi
• RUGZAK ALPINISM 22
• Anker PowerCore 20000 nrog Them Ceev 3.0
• Raspberry Pi Qauv B+ 512MB RAM
• ARDUINO UNO REV3 SMD
• Mifare RFID daim npav
• 1M x 0.5M grey PVC phaj
• Pattex hotmelt gluesticks
• 2x square hinges 25mm x 25mm
• Hlau nplaum xauv 4kg
• Poj niam rau poj niam jumper cables

Qee lub vev xaib yog Dutch hauv BOM.xlsx cov ntaub ntawv yog ob peb txoj hauv kev txuas ib yam nkaus.

Kauj ruam 2: Teeb

Ib ntawm qhov tsis meej pem tshaj plaws ntawm DIY raspberry pi cov phiaj xwm yog teeb tsa software kom raug. Nws tuaj yeem ua kev hem thiab nws nyuaj rau tus tswv.

Thawj qhov koj yuav tsum tau ua hauv Raspberry pi project yog txhim kho Raspbian ntawm koj Pi. Kuv tsis mus hla kev teeb tsa tag nrho tab sis ntawm no yog qhov txuas rau cov lus qhia: Raspberry-Pi-Teeb-Tutorial.

Tom qab kev teeb tsa muaj ntau pawg lus txib koj yuav tsum ua.

Ua ntej tshaj plaws hla tag nrho cov lus txib no:

github.com/NMCT-S2-DataCom1/DataCommunicat…

Tom qab ntawd ua raws cov lus txib no:

github.com/NMCT-S2-Project-I/Project-I

Kauj Ruam 3: Soldering thiab Circuit

Npaj kom tau koj txhais tes qias neeg? Nov yog qhov lom zem ib feem: txuas tag nrho koj cov khoom siv hluav taws xob.

RFID-nyeem ntawv, GPS-breakout thiab Neopixel tuaj ua neej tsis muaj pins soldered rau. Qhov no txhais tau tias koj tseem yuav muaj qee yam haujlwm ua haujlwm ua.

Nco ntsoov tias koj tau siv cov khoom lag luam zoo txaus kom tsis muaj tus pin ua rau sib cuag (qhov no tuaj yeem ua rau hluav taws xob tawg).

Ntawm RFID-nyeem ntawv tsuas yog siv cov pins koj xav tau, koj yuav txo qis txoj hauv kev hlawv cov pins. Muaj 2 lub jumper xav tau rau RFID-nyeem ntawv. Thawj qhov 'SEL0' yuav tsum tau teeb tsa rau 'tawm', qhov thib ob 'SEL1' yuav tsum tau teeb tsa rau 'rau'.

Kuv tau siv T-cobbler thiab lub khob cij thaum sim, tab sis thaum kawg kuv tau pov lawv tawm vim tias lawv siv ntau qhov chaw.

GPS thiab Arduino txuas nrog Pi trough serial USB txuas. Nws muaj peev xwm txuas Adafruit neopixel ncaj qha rau Pi tab sis koj yuav tsum tau siv qib hloov pauv thiab nws yog qhov nyuaj ntau dua thaum siv qhov txuas txuas.

Tsis txhob muab koj cov hlau tso pov tseg tam sim no, tej zaum koj yuav xav tau nws ntau dua hauv cov lus qhia no.

Kauj ruam 4: Database

Txhua yam hauv lub database yog txuas nrog. Nws txhua tus pib nrog tus neeg siv, tus neeg siv muaj lub hnab ev ntawv thiab lub hnab ev ntawv muaj ob peb yam ntxiv. Lub hnab ev ntawv tuaj yeem muaj cov dej num thiab cov dej num muaj ib lossis ntau cov ntaub ntawv.

Nco ntsoov tias koj tsis khaws tus password ntawm koj cov neeg siv li cov ntawv yooj yim.

Kauj Ruam 5: Tsim Rooj Plaub

Offcourse peb tsis ntim txhua yam hauv hnab ev khoom yam tsis muaj rooj plaub.

Txhawm rau ua rooj plaub, Kuv tau siv 3mm PVC ua npuas ncauj.

Nws yog lub thawv plaub fab ua los ntawm 6 daim PVC.

2 x (19.5 cm - 9.5 cm)

2 x (19.5 cm - 3 cm)

2 x (9.5 cm - 3 cm)

Cov phaj sib txawv tau ua ke nrog cov kua nplaum kub.

Yog tias koj siv tib lub hnab ev ntawv zoo li kuv tau ua, tsis txhob ua qhov ntev me dua vim tias nws tsis haum.

Kuv tau txiav qee lub qhov hla ob sab ntawm lub npov kom tuaj yeem tso kuv cov hlua hauv kuv tus Pi.

Txhawm rau tuav Pi thiab arduino nyob rau hauv qhov chaw, Kuv tau glued qee cov phaj me me ntawm sab hauv ib puag ncig lawv.

Lub teeb tau tuav hauv qhov chaw los ntawm 2 lub pob khawm thiab nws tau kaw nrog cov hlau nplaum.

Qhov kawg ntawm lub npov muaj lub qhov kom khiav tag nrho cov kab xev.

Yog tias cov xaim hluav taws xob tsis ntev txaus koj yuav xav tau txuas qee qhov ntawm lawv ua ke.

Thaum lub thawv tiav, koj tuaj yeem tso nws rau hauv koj lub hnab ev ntawv. Kuv tau txiav qee qhov me me hauv kuv lub hnab ev khoom kom khiav qee cov kab txuas.
