Nqe lus piav qhia:

SaferWork 4.0 lub hom phiaj los muab cov ntaub ntawv ib puag ncig ib puag ncig ntawm cov chaw tsim khoom. Tam sim no muaj cov kev cai xws li OHSAS 18001 (Kev Ua Haujlwm Saib Xyuas Kev Noj Qab Haus Huv thiab Kev Nyab Xeeb Kev Nyab Xeeb) lossis Brazilian NR-15 (Cov haujlwm tsis zoo) txiav txim siab tshuaj xyuas ib ntus txhawm rau cais cov cheeb tsam thiab thov kom txo qis. Cov xwm txheej tsis tu ncua tsis raug ntes los ntawm kev tshuaj xyuas ib ntus thiab tuaj yeem ua rau cov neeg ua haujlwm raug mob vim tsis muaj kev txo qis.

Hauv lub tswv yim ntawm cov khoom faib tawm thiab lub qhov rooj loj, cov ntsuas tau faib rau hauv cov chaw tsim khoom lag luam txhawm rau ntsuas cov xwm txheej ib puag ncig thiab cov ntaub ntawv no tau nthuav tawm hauv lub dashboard muaj rau Cov Kws Saib Xyuas Kev Nyab Xeeb, Cov Kws Kho Mob, Up Management, Human Resources thiab ntau lwm yam, txhawb kev nkag siab tseem ceeb kom muaj kev phom sij rau kev tshuaj xyuas thiab txo kev nqis tes ua txhawm rau txo lossis tiv thaiv kev raug mob thiab xwm txheej.

Txoj kev ntsuas ua qauv tam sim no:

• Kub
• Vaum
• Cov Roj (Huab Cua Zoo, Cov Hluav Taws Xob, Cov Hluav Taws Xob thiab Cov Pa)

Yuav tsum tau ua:

Suab nrov

Nws ua haujlwm li cas

Cov cuab yeej xa JSON pob uas muaj cov ntaub ntawv ntsuas mus rau lub qhov rooj uas yuav txheej txheem thiab xa nws mus rau huab (dweet.io) thiab tseem muab nws ntawm lub dashboard (freeboard.io).

Daim Ntawv Teev Npe - Kho Vajtse

1. Rooj vag

   1. Qualcomm Dragonboard 410c (Debian Linux)
   2. HC-12 Wireless Transceiver (Cov Ntaub Ntawv)
   3. Qib Shifter los hloov Dragonboard 1.8V rau 5V (Cov Ntaub Ntawv)

2. Ntaus ntawv

   1. Arduino Ib
   2. HC-12 Wireless Transceiver (Cov Ntaub Ntawv)
   3. DHT-11 Kub thiab Vaum Sensor (Cov Ntaub Ntawv)
   4. MQ -2 - rhiab heev rau cov nplaim hluav taws thiab cov hluav taws kub hnyiab tau (Methane, Butane, LPG, haus luam yeeb) (Cov ntaub ntawv)
   5. MQ -9 - Raug rau Carbon Monoxide, cov nplaim taws (Cov Ntawv Teev Npe)
   6. MQ -135 - Rau Huab Cua Zoo (rhiab rau Benzene, Cawv, haus luam yeeb) (Cov ntaub ntawv)

Kauj Ruam 1: Kev Siv Khoom Siv

Cov cuab yeej nruab nrab yog lub txaj ntsuas kom nyob hauv ntau thaj chaw hauv thaj chaw tsim khoom kom pom tseeb ib puag ncig ib puag ncig.

Hauv qhov haujlwm no tau siv Arduino Uno Platform nrog 3 lub ntsuas pa (MQ-2, MQ-9 thiab MQ-135), 1 qhov ntsuas kub/av noo (DHT-11) thiab lub tshuab xa xov RF (HC-12).

Arduino rau Sensors Pinout:

Analog

• A1 rau DHT11 analog pin
• A3 rau MQ135 analog pin
• A4 rau MQ9 analog pin
• A5 rau MQ2 analog pin

Cov

• D7 rau HC-12 SET tus pin
• D10 rau HC-12 TX tus pin (teeb tsa ua RX ntawm Arduino)
• D11 rau HC-12 RX tus pin (teeb tsa ua TX ntawm Arduino)

Kauj Ruam 2: Kev Siv Qhov Rooj

Raws li tau hais los ntawm Wikipedia:

"Internet of Things (IoT) Gateway muab txoj hauv kev txhawm rau txhawm rau sib txawv ntawm cov khoom siv hauv thaj chaw (hauv tsev hauv tsev, hauv tsev, thiab lwm yam), Huab, qhov twg khaws cov ntaub ntawv, khaws cia thiab tswj los ntawm cov ntawv thov lag luam, thiab cov khoom siv."

Txhawm rau siv txoj haujlwm no peb siv Qualcomm Dragonboard 410c. Ua ke nrog Dragonboard peb siv qib ob-qib kev hloov pauv, los hloov Dragonboard kev ua haujlwm ntawm 1.8V rau HC-12 RF Transceiver Kev Ua Haujlwm Voltage ntawm 5V.

Dragonboard 410c kuj tau teeb tsa nrog Debian/Linaro Linux.

Dragonboard 410c Pinout li Rooj vag:

• Tus Ceev Txuas Tus Pin 5 (TxD) -> Qib Shifter -> HC -12 RX Pin
• Tsawg Tus Txuas Txuas 7 (RxD) <- Qib Shifter <- HC-12 TX Pin
• Tsawg Tus Txuas Txuas Tus Pin 29 (GPIO) -> Qib Shifter -> HC -12 SET Pin

Txoj cai tau siv hauv Python txhawm rau teeb tsa Kev Pabcuam Gateway tuaj yeem tau txais hauv qhov project GitHub chaw cia khoom:

github.com/gubertoli/SaferWork/blob/master/SaferWork_Gateway.py

Nws yog ib qho tseem ceeb uas yuav tsum tau hais tias txoj haujlwm no siv dweet.io xa cov ntaub ntawv xov tooj thiab cov ntaub ntawv no tau siv ntawm qhov kev pabcuam freeboard.io raws li qhia hauv theem no.

Kev teeb tsa dweet.io yog qhov yooj yim heev thiab tuaj yeem nkag siab los ntawm cov lus hais tawm qhov chaws. Freeboard.io yog tus tsim cov dashboard uas nkag siab ncaj qha nrog dweet.io.

Kauj Ruam 3: Xaus

Cov Teeb Meem Thaum Kev Txhim Kho

Wireless Transceiver Txhais Lus

Thaum lub sijhawm tsim cov tswv yim nws tau txiav txim siab raug 443 MHz RX/TX circuits (RT3/4 thiab RR3/4) nrog qhov txwv qis thiab uas yuav tsum tau ua tshwj xeeb rau kev khaws cov ntaub ntawv (piv txwv). Txhawm rau kov yeej txhua qhov kev nyuaj no nws tau hloov pauv rau HC-12 Tus xa xov uas suav tag nrho cov khoom siv hluav taws xob rau rx/tx muab cov ntaub ntawv meej meej ncaj qha rau Dragonboard zam kev ua haujlwm nyuaj thiab txaus ntshai ntawm qhov kev xaiv ua ntej.

Dragonboard 410c Qib Shifter

Nws tau muab Linker Sprite Mezzanine nrog Qib Shifter rau UART tab sis Chaw nres nkoj yog tib yam li ib qho siv los ntawm OS rau kev sib txuas lus sib txuas (Tsawg Ceev txuas Pins 11-TX thiab 13-RX) nthuav tawm cov teeb meem thaum siv, yog li nws xav tau siv lwm qhov muaj UART chaw nres nkoj (Tsawg Ceev Txuas Txuas 5-TX thiab 7-RX) uas tsis muaj nyob ntawm Linker Sprite Mezzanine nrog Qib Shifter, yog li nws xav tau kom tau txais ib qho. Ua ntej yuav yuav ib qho tshwj xeeb rau qhov uas nws tau sim siv lub transistor qhib qib hloov pauv uas tsis ua haujlwm rau UART siv.
