Cov tshuab tig xws li cua tshuab cua, lub tshuab hluav taws xob, lub tshuab hluav taws xob thiab lwm yam ntsej muag sib txawv ntawm hnav thiab kua muag. Feem ntau ntawm cov kev ua txhaum no thiab hnav thiab tsim kua muag tshwm sim los ntawm kev ua tsis zoo hauv lub cuab yeej. Cov tshuab no feem ntau ua haujlwm nyob rau hauv lub luag haujlwm hnyav thiab nrog lub sijhawm poob qis. Qhov ua txhaum loj uas tshwm sim hauv cov no yog cov hauv qab no

• Tsis sib xws radial thiab tangential rog.
• Kev coj tus cwj pwm tsis xwm yeem.
• Bearing faults, rotor bar thiab qhov xaus ntawm qhov yuam kev thaum muaj cov tawb tawb induction
• Lub cev tsis muaj zog stator thiab huab cua sib txawv eccentricity hauv rotors.

Cov kev tsis sib haum no tuaj yeem ua rau lub tshuab puas sai dua. N nrov nrov thiab tuaj yeem cuam tshuam rau kev coj ua ntawm lub tshuab. Kev Tshawb Fawb Kev Tshawb Fawb thiab Kev Txhim Kho Ua Ntej muab cov ncauj lus ntxaws ntxaws ntawm kev txheeb xyuas, qhov chaw thiab kuaj mob ntawm qhov ua tsis raug hauv kev sib hloov thiab rov ua cov tshuab siv kev tshuaj xyuas kev co. Hauv Cov Lus Qhia no peb yuav siv Wireless Vibration Sensor txhawm rau kov yeej qhov teeb meem no. Cov ntsuas no yog cov qib ntsuas hluav taws xob thiab tau ua tiav siv rau hauv ntau daim ntawv thov xws li Kev tshuaj xyuas cov qauv ntawm kev tsim vaj tsev pej xeem, kev tshuaj xyuas kev co ntawm cua tshuab cua, kev tshuaj ntsuam kev co ntawm lub tshuab hluav taws xob. Peb yuav pom thiab txheeb xyuas cov ntaub ntawv kev co hauv Cov Lus Hais. Ntawm no peb yuav nthuav tawm cov hauv qab no.

• Wireless Kev co thiab Kub Sensors.
• Kev ntsuas kev co siv cov Sensors no.
• Sib sau cov ntaub ntawv siv Wireless rooj vag ntaus ntawv
• Xa cov ntaub ntawv kev co mus rau Qhov Hais Lus IoT platform siv Qhov Hais Lus MQTT API.

Kauj Ruam 1: Khoos phis tawj thiab khoos phis tawj tshwj xeeb

Specification ntawm Software

• Ib qho ThingSpeak tus account
• Arduino IDE Cov

Kho vajtse Specification

• ESP32
• Wireless Kub thiab Kev Ruaj Ntseg Sensor
• Zigmo Gateway tus txais

Kauj Ruam 2: Cov Lus Qhia los Xyuas Kev Ruaj Ntseg hauv Cov Tshuab Rotating

Raws li tau hais hauv qhov kawg qhia "Mechanical Vibration Analysis of Induction Motors". Muaj qee cov lus qhia uas yuav tsum tau ua raws li txhawm rau cais cov kev ua txhaum thiab ua txhaum kev txheeb xyuas qhov kev co. Rau qhov kev sib hloov nrawm nrawm nrawm yog ib qho ntawm lawv. Kev sib hloov nrawm nrawm yog tus yam ntxwv ntawm kev ua txhaum sib txawv.

• 0.01g lossis Tsawg - Zoo heev - Lub tshuab ua haujlwm tau zoo.
• 0.35g lossis tsawg dua - Mob zoo. Lub tshuab ua haujlwm zoo. Tsis tas yuav tsum ua tshwj tsis yog lub tshuab nrov nrov. Yuav muaj qhov rotor eccentricity txhaum.
• 0.75g lossis ntau dua - Rough Condition- Yuav tsum tau tshuaj xyuas lub cav muaj peev xwm ua rau rotor tsis txaus ntseeg yog tias lub tshuab ua suab nrov ntau dhau.
• 1g lossis ntau dua - Mob hnyav heev - Muaj qhov ua txhaum loj hauv lub cav. Qhov ua txhaum yuav yog los ntawm kev ua txhaum lossis khoov ntawm lub bar. Txheeb xyuas lub suab nrov thiab qhov kub
• 1.5g lossis ntau dua- Qib txaus ntshai- Yuav tsum tau kho lossis hloov lub cav.
• 2.5g lossis Ntau Ntxiv -Severe Level -Kaw lub tshuab tam sim ntawd.

Kauj Ruam 3: Tau Txais Qhov Kev Ntsuas Kev Ntsuas Siab

Qhov kev co muaj nuj nqis, uas peb tau txais los ntawm cov ntsuas tau nyob hauv milis. Cov no suav nrog cov txiaj ntsig hauv qab no.

RMS tus nqi-lub hauv paus txhais tau tias square qhov tseem ceeb nrog rau txhua peb txoj kab

ncov rau ncov tus nqi = RMS tus nqi/0.707

• Tus nqi tsawg- Tus nqi tsawg kawg nkaus nrog rau txhua peb txoj kab
• Max qhov tseem ceeb-ncov mus rau qhov siab tshaj plaws nrog rau txhua peb txoj kab. Tus nqi RMS tuaj yeem suav nrog siv cov mis no

RMS tus nqi = ncov mus rau qhov siab tshaj x 0.707

Ua ntej thaum lub cav tau zoo peb tau txais qhov txiaj ntsig ib puag ncig 0.002g. Tab sis thaum peb sim nws ntawm lub cev tsis raug lub cev qhov kev vibration peb tshuaj xyuas yog kwv yees li 0.80g txog 1.29g. Lub cev tsis ua haujlwm raug rau siab rotor eccentricity. Yog li, peb tuaj yeem txhim kho qhov ua txhaum kev zam ntawm lub cev siv lub tshuab Kev co.

Kauj Ruam 4: Teeb tsa Qhov Hais Lus

Txog kev tshaj tawm peb qhov kub thiab txias qhov tseem ceeb rau huab peb tab tom siv ThingSpeak MQTT API. ThingSpeak yog IoT platform. ThingSpeak yog lub vev xaib pub dawb uas tso cai rau koj sau thiab khaws cov ntaub ntawv sensor hauv huab. MQTT yog cov txheej txheem ib txwm siv hauv IoT cov kab ke los txuas cov cuab yeej qis thiab cov ntsuas. MQTT yog siv los xa cov lus luv rau thiab los ntawm tus tswv lag luam. ThingSpeak tsis ntev los no tau ntxiv MQTT broker kom cov khoom siv tuaj yeem xa xov mus rau ThingSpeak. Koj tuaj yeem ua raws cov txheej txheem los teeb tsa ThingSpeak Channel los ntawm cov ntawv no

Kauj Ruam 5: Tshaj Tawm Tus Nqi rau ThingSpeak Account

MQTT yog tshaj tawm/sau npe ua vaj tsev uas tau tsim los txuas rau txuas bandwidth thiab lub zog-txwv cov cuab yeej hla wireless tes hauj lwm. Nws yog cov txheej txheem yooj yim thiab hnyav uas ua haujlwm dhau TCP/IP qhov nyob lossis WebSockets. MQTT hla WebSockets tuaj yeem ruaj ntseg nrog SSL. Kev tshaj tawm/sau npe ua haujlwm ua kom cov lus raug thawb mus rau cov neeg siv khoom yam tsis muaj lub cuab yeej xav tau los mus pov ntawv tawm suab tsis tu ncua.

Tus neeg siv khoom yog ib qho khoom siv uas txuas rau tus broker thiab tuaj yeem tshaj tawm lossis sau npe rau cov ncauj lus kom nkag tau cov ntaub ntawv. Ib lub ncauj lus muaj cov ntaub ntawv qhia txog tus broker. Txhua tus neeg siv khoom uas xav xa lus tshaj tawm lawv mus rau qee lub ncauj lus, thiab txhua tus neeg siv khoom uas xav tau txais cov lus sau npe rau qee lub ncauj lus

Tshaj tawm thiab sau npe siv ThingSpeak MQTT

• Tshaj tawm rau cov channel pub pub rau/"channelID"/tshaj tawm/"WriteAPIKey"

• Tshaj tawm rau ib qho chaw tshwj xeeb

  raws/

  "channelID" /tshaj tawm /teb /"fieldNumber" /"fieldNumber"

• Sau npe yuav ua rau cov channel teb

  raws/

  "channelID" /subscribe /"format" /"APIKey"

• Sau npe yuav mus rau tus kheej channel pub

  raws/

  channelID

  /subscribe/fields/"fieldNumber"/"hom ntawv"

• Sau npe yuav ua rau txhua qhov ntawm cov channel. raws /

  "channelID"/

Kauj Ruam 6: Pom qhov pom cov ntaub ntawv Sensor ntawm ThingSpeak

Kauj Ruam 7: Email ceeb toom rau Kev Ceeb Toom Kev Nyab Xeeb

Peb tab tom siv IFTTT cov ntawv thov los tshaj tawm huab cua lub sijhawm tiag tiag Email ceeb toom rau tus neeg siv. Yog xav paub ntxiv txog IFTTT teeb tsa koj tuaj yeem hla qhov blog no. Yog li, Peb tau siv nws los ntawm ThingSpeak. Peb tab tom xa email ceeb toom rau tus neeg siv thaum twg hloov pauv qhov kub thiab txias tshwm sim hauv tshuab. Nws yuav ua rau email ceeb toom "Hnub zoo nkauj npaum cas". Txhua txhua hnub nyob ib ncig ntawm 10:00 teev sawv ntxov (IST) peb yuav tau txais email ceeb toom

Kauj Ruam 8: Txoj Cai Tag Nrho

Lub khoos phis tawj ntawm kev teeb tsa no tuaj yeem pom hauv GitHub qhov chaw cia khoom no
