2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:25

Raws li kuv tau nug kuv tus kheej ntau npaum li cas tam sim no tau muab los ntawm kuv ISP (Kuv siv LTE modem rau kev txuas Is Taws Nem), Kuv xav txog qhov ntsuas kab ke bandwidth. Txij li lub kaw lus yuav tsum ua kom me me thiab txuag hluav taws xob, Kuv tau xaiv Raspberry Pi Zero ua lub hauv paus tseem ceeb. Raspberry txuas nrog lub modem ntawm WLAN, yog li WLAN teeb meem tuaj yeem kuaj pom ib yam.

Khoom siv

• Raspberry Pi Zero WH
• Waveshare e-ink zaub (2.9inch-e-paper-module)
• DC-DC hloov pauv (piv txwv li DEBO DCDC 20W)
• RGB LED (tshem tawm los ntawm lub cuab yeej qub)
• Laub-khawm
• Hloov
• Relais module (piv txwv li 2 Way Relay module2 Way Relay module)
• Txiv neej txuas + Poj niam txuas (ob leeg haum qhov loj ntawm koj lub modem fais fab mov ntsaws)
• Cov ntawv luam tawm 3D

Kauj ruam 1: Nta

• Raspberry Pi Zero tau txuas nrog ntawm WLAN, ntsuas kev nce thiab rub tawm nrawm thiab ua qhov ntsuas ping txhua ib nrab teev. Ib kab hais kom ua version ntawm speedtest.net tau siv los ua lub hauv paus rau kev ntsuas.
• Qhov tshwm sim ntawm kev ntsuas bandwidth thiab ping tau qhia ntawm e-ink zaub. Lub sijhawm ntsuas kuj tseem pom.
• Yog tias qhov rub tawm nrawm poob qis dua tus nqi pib txhais, tus xa tawm hloov lub modem tawm thiab nyob rau lub sijhawm luv. Lub modem yog li rov pib dua yam tsis muaj kev hloov kho ntawm lub cuab yeej (tsuas yog lub zog txuas raug cuam tshuam).
• Ib lub pob nyob rau pem hauv ntej ntawm lub cuab yeej muaj los txhawm rau ntsuas qhov ntsuas qhov ntsuas tus kheej.
• Qhov ntsuas ntsuas tau muab tso rau ntawm Ubidots Dashboard (IOT Portal). Hauv cov ntsiab lus koj tseem tuaj yeem pom lub sijhawm keeb kwm ntawm qhov ntsuas ntsuas thiab yog vim li cas rau qhov rov pib dua.
• Hauv IOT Portal koj tseem tuaj yeem pom lub pob kom rov pib dua lub modem.
• Bandwidth saib xyuas siv lub hwj chim ntawm tus qauv. Tsis xav tau khoom ntxiv. Cov kev cuam tshuam cuam tshuam kev xa cov xa hluav taws xob mus rau lub modem - raspberry tseem tau hloov pauv.

Kauj ruam 2: Kev thaiv kab

Hauv thawj daim duab koj tuaj yeem pom tus tsim sab hauv ntawm bandwidth saib:

Cov khoom loj yog:

1. Laub khawm
2. E-ink Zaub
3. Raspberry Pi Zero
4. Relay Module
5. RGB LED + Resistors (nyob ntawm RGB LED koj siv)
6. Hloov
7. DC-DC Hloov
8. Poj niam txuas

Daim duab thib ob qhia txog cov txheej txheem ntawm cov thaiv. Tus ncej zoo ntawm cov khoom siv hluav taws xob tau pub los ntawm kev hloov mus rau DC-DC qhov hloov hluav taws xob (uas hloov 12V lub zog hluav taws xob ntawm lub router rau 5V rau Raspberry) thiab ntawm kev xa tawm (ntawm tus lej txuas nrog tus pin) rov qab mus rau cov zis txuas. Yog li cov modem tseem tau muab nrog lub zog thaum qhov ntsuas bandwidth raug kaw.

Qhov ntsuas bandwidth tuaj yeem pib ua haujlwm ntawm lub pob. Ib qho RGB LED tau siv los pom txog ntau lub xeev ua haujlwm.

Qhov kev sib txuas ntawm Raspberry Pi thiab e-ink zaub tsis pom hauv daim duab kos. Txuas cov zaub raws li lub rooj thiab tus pin-tawm saum toj no.

Kauj ruam 5: Software

Lub software tau faib ua ob peb cov ntaub ntawv / cov haujlwm:

bandwidth_monitor_0_4.py yog qhov haujlwm tseem ceeb uas tau thov los ntawm Crontab txhua txhua ib nrab teev. Nws ua qhov ntsuas bandwidth (ntawm kab lus hais kom ua version ntawm speedtest.net). Thaum kuaj, RGB LED yog xiav. Yog tias qhov bandwidth siab dua qhov xaiv tau pib, tus nqi tau qhia ntawm e-ink zaub (nrog rau lub sijhawm) thiab xa tawm mus rau Ubidots dashboard. Yog tias qhov bandwidth qis dua qhov pib LED tig liab thiab ntsuas rov ua dua tom qab ncua sijhawm luv. Tom qab 3 qhov kev sim tsis zoo qhov kev xa tawm tau qhib thiab yog li lub zog hluav taws xob ntawm lub modem raug cuam tshuam. Pib dua txoj cai (tus nqi = 2) tau sau rau ntu ntu.

poll_killswitch.py nyeem cov xwm txheej ntawm boolean sib txawv ntawm lub dashboard. Yog tias killswitch_state muaj tseeb qhov relais tau qhib lub zog hluav taws xob ntawm lub modem raug cuam tshuam. RGB LED hloov ntsuab thaum lub sij hawm pov npav ntawm tus tua. Tom qab rov pib dua killswitch_state tau teeb tsa cuav thiab nkag mus rau ntu ntu ntawm lub dashboard tau tsim (tus nqi = 1).

poll_test_now_button.py tab tom tos lub pob nyem ntawm lub vaj huam sib luag pem hauv ntej ntawm rooj plaub kom raug nias. Los ntawm kev qhib lub pob, ntsuas ntsuas bandwidth tau ua rau tus kheej. Thaum qhov haujlwm pib (ntawm kev rov pib dua ntawm Raspberry Pi) RGB LED tab tom ntsais liab.

post_restart_message.py sau qhov pib dua tus lej (tus nqi = 3) rau ntu ntu ntawm lub dashboard. Qhov no qhia tias bandwidth saib tau rov pib dua. Thaum lub sijhawm pib ua haujlwm RGB LED teeb ci xiav.

test_LED.py thiab test_relay.py yog cov ntawv yooj yim uas tuaj yeem siv los ntsuas qhov ua haujlwm ntawm RGB LED thiab kev xa tawm.

epdconfig.py thiab epd2in9.py yog cov cuab yeej tsav tsheb rau e-ink zaub muab los ntawm Waveshare.

Txhawm rau tso cai rau cov haujlwm kom nkag mus rau Ubidots dashboard, koj yuav tsum ntxiv koj tus kheej tokens thiab cov cuab yeej lossis cov npe sib txawv (yog tias koj siv cov cim sib txawv). Tshawb nrhiav ntu zoo li qhov pom hauv daim duab saum toj no (hloov XXXXXXXX los ntawm koj tus cim).

Cov ntawv qhia ntxaws ntxaws txog yuav tsim lub dashboard thiab yuav ua li cas sib xyaw lub dashboard rau hauv Python program tuaj yeem pom ncaj qha ntawm Ubidots nplooj ntawv (https://help.ubidots.com/en/) lossis ntawm Google.

Kauj Ruam 6: IOT Dashboard

Lub dashboard tuav los ntawm Ubidots (saib https://ubidots.com) muaj ntau qhov chaw uas tau piav qhia luv luv hauv qab no.

1. Sijhawm ntu ntawm nce- thiab rub tawm nrawm. Txhua ib nrab teev tus nqi tshiab raug ntxig rau hauv daim duab.
2. Lub sijhawm kawm ntawm lub sijhawm ntsuas ping. Txhua ib nrab teev tus nqi tshiab tau ntxig rau hauv daim duab.
3. Lub sijhawm ua ntu zus ntawm qhov nruab nrab rub tawm nrawm. Tus nqi nruab nrab tshaj 24 teev yog xam thiab sau rau daim duab.
4. Spreadsheet sawv cev ntawm qhov ntsuas tam sim no suav nrog lub sijhawm thwj cim.
5. Cov chaw taws teeb tswj kom rov pib dua lub modem ntawm Is Taws Nem. Kev nug tshwm sim txhua 3 feeb, piv txwv li nws yuav siv qee lub sijhawm kom txog thaum qhov kev ua tiav tiav.
6. Nkag ntawm qhov rov pib dua suav nrog qhov laj thawj rau kev rov pib dua (ua rau thaj chaw deb, hloov tawm lossis poob qhov hluav taws xob, poob qis dua qhov tsawg kawg bandwidth)
