Taw qhia

Ib lub tuam txhab Asmeskas paub zoo raws li lub tuam txhab qoj ib ce (Wahoo) tsis ntev los no tau nthuav tawm kev qhia sab hauv tsev zoo uas nce thiab txo qis pem hauv ntej ntawm lub tsheb kauj vab ntawm tus kws qhia turbo raws li qib simulated ntawm toj uas tus neeg siv caij (Kickr Climb).

Zoo li tsis txaus ntseeg tab sis tu siab qhov no tsis muaj rau peb txhua tus raws li koj xav tau 1) sab saum toj ntawm thaj tsam Wahoo tus kws qhia thiab 2) cash 500 nyiaj ntsuab los ua qhov no rau koj li.

Kuv tsoo lub clavicle (tsis txhob tso tus neeg caij tsheb kauj vab ntawm lub tsheb kauj vab roob) yog li kuv muaj ntau mais ntawm tus kws qhia thiab ntau lub sijhawm rau tinker thiab xav tias qhov no tuaj yeem yog txoj haujlwm lom zem.

Chav ua lag luam simulates -5% rau +20% yog li kuv xav los ze rau qhov ntawd tab sis ntawm 10% ntawm pob nyiaj siv!

Qhov no tau tsim nyob ib puag ncig kuv Tacx Neo tab sis ib tus kws qhia uas tshaj tawm nws lub zog thiab cov ntaub ntawv nrawm ntawm ANT+ lossis BLE tuaj yeem ua haujlwm (Kuv xav!)

Txij li lub hauv paus log ntawm kuv txoj kev tsheb kauj vab ntsuas qhov tseeb 1000mm Kuv yuav tsum tau nqa lub diav rawg los ntawm 200mm los simulate 20% (saib daim duab) yog li 200mm linear actuator yuav ua. Lub tsheb kauj vab + tus neeg hnyav hnyav tsis zoo li ntau dua 100kg thiab vim qhov no tau faib tawm ntawm cov qag thiab feem ntau yog nyob tom qab 750N yuav nqa 75kg thiab yuav tsum ua li cas. Cov neeg ua haujlwm nrawm muaj rau nyiaj ntau dua tab sis qhov no raug nqi kuv ib ncig £ 20 thiab tswj 10 hli/sec. Actuators nrog lub zog ntsuas uas tuaj yeem siv tau yooj yim servos kuj tseem yog 2 txog 3 zaug kim dua.

Kauj Ruam 1: Qee Zauv

Peb yuav tsum suav cov kab uas tau simulated. Kuv tau cia siab tias tus kws qhia yuav tshaj tawm cov ntaub ntawv no nrog rau kev nrawm, lub zog, kev ua haujlwm thiab lwm yam. Kuv tsis muaj txoj hauv kev yooj yim mus ntes 'qib simulated' los ntawm software yog li kuv yuav tau ua haujlwm rov qab …

Lub zog ua haujlwm ntawm lub tsheb kauj vab thiab tus neeg caij tsheb yog sib xyaw ua ke ntawm kev tiv thaiv kev poob thiab lub zog xav tau kom nce toj. Tus kws qhia qhia ceev thiab lub zog. Yog tias peb tuaj yeem pom qhov kev tiv thaiv poob ntawm qhov nrawm tau muab tso rau ntawd lub zog uas siv tau yog nce toj. Lub zog nce mus yog nyob ntawm qhov hnyav ntawm lub tsheb kauj vab thiab tus neeg caij tsheb thiab tus nqi nce thiab yog li peb tuaj yeem rov ua haujlwm rov qab.

Ua ntej kuv siv qhov zoo https://bikecalculator.com txhawm rau nrhiav qee cov ntsiab lus cov ntaub ntawv rau kev tiv thaiv lub zog poob ntawm qhov nrawm. Tom qab ntawd kuv hloov pauv qhov nrawm los tsim txoj kev sib raug zoo thiab pom kab zoo tshaj plaws. Noj cov kab zauv ntawm kab tam sim no peb tuaj yeem suav lub zog (W) los ntawm kev tawm tsam = (0.0102*(Speedkmh^2.8))+9.428.

Siv lub zog los ntawm kev tiv thaiv los ntawm lub zog ntsuas kom muab lub zog ntawm 'nce toj'.

Peb paub qhov nrawm ntawm nce hauv km/hr thiab hloov qhov no mus rau SI units ntawm m/s (faib los ntawm 3.6).

Kev pom tau pom los ntawm: Kab rov qab (%) = ((PowerClimbing/(WeightKg*g))/Ceev)*100

qhov twg nrawm ntawm lub caij nplooj zeeg dawb g = 9.8m/s/s lossis 9.8 N/kg

Kauj ruam 2: Tau Qee Cov Ntaub Ntawv

Kev suav xam xav tau nrawm thiab lub zog. Kuv siv Arduino Nano 33 IoT los txuas rau tus kws qhia ntawm BLE kom tau txais qhov no. Kuv tau nyam heev thaum xub thawj raws li v.1.1.2 tam sim no ntawm ib txwm tsev neeg ArduinoBLE lub tsev qiv ntawv rau cov qauv no tsis ua haujlwm txheeb xyuas qhov tseeb hauv txhua daim ntawv uas txhais tau tias feem ntau (?) Kev lag luam BLE sensors yuav tsis ua ke nrog nws.

Qhov kev daws teeb meem yog siv NPE Cable ANT+ rau BLE choj (https://npe-inc.com/cableinfo/) uas ua rau BLE ntawm tus kws qhia pub dawb rau kev qhia app txhawm rau sib tham thiab tsis xav tau kev lees paub ntawm BLE sab.

Lub zog BLE tus yam ntxwv yog qhov yooj yim zoo li lub zog hauv watts muaj nyob hauv qhov thib ob thiab thib peb bytes ntawm cov ntaub ntawv xa mus raws li 16 tus lej ntxiv (me ntsis endian piv txwv li tsawg kawg qhov tseem ceeb octet thawj). Kuv tau thov lub lim nruab nrab txav los muab 3s lub zog nruab nrab - ib yam li kuv lub tsheb kauj vab khoos phis tawj qhia pom - vim qhov no tsis txawv txav.

yog (powerCharacteristic.valueUpdated ()) {

// Txhais qhov array rau tus nqi uint8_t tuav lub zog [6] = {0, 0, 0, 0, 0, 0, 0}; // Nyeem tus nqi rau hauv array powerCharacteristic.readValue (tuav lub zog, 6); // Lub zog raug xa rov qab raws li cov watts hauv qhov chaw 2 thiab 3 (loc 0 thiab 1 yog 8 tus chij) byte rawpowerValue2 = tuav lub zog [2]; // lub zog tsawg kawg sig byte hauv HEX byte rawpowerValue3 = tuav lub zog [3]; // hwj chim feem ntau sig byte hauv HEX ntev rawpowerTotal = (rawpowerValue2 + (rawpowerValue3 * 256)); // Siv qhov txav nruab nrab lim los muab '3s zog' powerTrainer = movingAverageFilter_power.process (rawpowerTotal);

Tus yam ntxwv BLE nrawm (Cycling Speed thiab Cadence) yog ib yam uas ua rau koj xav tsis thoob hauv ntiaj teb SIG tau haus luam yeeb thaum lawv sau cov lus qhia tshwj xeeb.

Tus Cwj Pwm rov qab los ntawm 16 byte array uas tsis muaj qhov nrawm lossis tsis ua haujlwm. Hloov chaw koj tau txais cov kiv puag ncig lub log thiab kev hloov pauv crank (tag nrho) thiab sijhawm txij li cov ntaub ntawv tshwm sim zaum kawg hauv 1024ths ntawm ob. Yog li ntau lej ua ntej. Auj, thiab cov bytes tsis tas li tam sim no yog li muaj tus chij byte thaum pib. Auj, thiab cov bytes me ntsis endian HEX yog li koj yuav tsum tau nyeem rov qab muab qhov thib ob byte los ntawm 256, thib peb los ntawm 65536 thiab lwm yam ces ntxiv lawv ua ke. Txhawm rau nrhiav nrawm koj yuav tsum xav txog tus qauv tsheb kauj vab ib puag ncig kom paub qhov nrug….

yog (speedCharacteristic.valueUpdated ()) {

// Tus nqi no xav tau 16 byte array uint8_t tuav cov nqi [16] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0} // Tab sis kuv tsuas yog nyeem thawj 7 speedCharacteristic.readValue (tuav tus nqi, 7); byte rawValue0 = tuav tus nqi [0]; // binary chij 8 ntsis int byte rawValue1 = holdvalues [1]; // revolutions yam tsawg kawg tseem ceeb byte hauv HEX byte rawValue2 = holdvalues [2]; // revolutions tom ntej tseem ceeb tshaj byte hauv HEX byte rawValue3 = holdvalues [3]; // revolutions tom ntej tseem ceeb tshaj byte hauv HEX byte rawValue4 = holdvalues [4]; // revolutions tseem ceeb tshaj byte hauv HEX byte rawValue5 = holdvalues [5]; // lub sijhawm txij li qhov xwm txheej zaum kawg tsawg kawg sig byte byte rawValue6 = holdvalues [6]; // lub sijhawm txij li qhov kev tshwm sim zaum kawg feem ntau sig byte yog (firstData) {// Tau txais cov log tig rov los li me ntsis endian hex hauv zos 2, 3 thiab 4 (tsawg kawg qhov tseem ceeb octet thawj) WheelRevs1 = (rawValue1 + (rawValue2 * 256) + (rawValue3 * 65536) + (rawValue4 * 16777216)); // Tau txais lub sijhawm txij li lub log tshwm sim zaum kawg hauv 1024ths ntawm Lub Sijhawm thib ob_1 = (rawValue5 + (rawValue6 * 256)); firstData = tsis tseeb; } lwm {{Tau txais cov txheej thib ob ntawm cov ntaub ntawv ntev WheelRevsTemp = (rawValue1 + (rawValue2 * 256) + (rawValue3 * 65536) + (rawValue4 * 16777216)); Ntev Sijhawm = (rawValue5 + (rawValue6 * 256)); yog (WheelRevsTemp> WheelRevs1) {// xyuas kom lub tsheb kauj vab txav mus WheelRevs2 = WheelRevsTemp; Sijhawm_2 = Sijhawm Sijhawm; firstData = tseeb;}

// Pom qhov sib txawv ntawm qhov sib txawv hauv cm thiab hloov mus rau km ntab debTravelled = ((WheelRevs2 - WheelRevs1) * wheelCircCM);

ntab kmTravelled = nrugTravelled / 1000000;

// Nrhiav sijhawm hauv 1024ths ntawm ib pliag thiab hloov mus ua teev

ntab timeDifference = (Sijhawm_2 - Sijhawm_1); ntab timeSecs = sijhawm sib txawv / 1024; ntab timeHrs = timeSecs / 3600;

// Nrhiav ceev kmh

speedKMH = (kmTravelled / timeHrs);

Kauj Ruam 3: Kho vajtse 1 tus Linear Actuator

Los ntawm lub qag ntawm kuv lub disc nres txoj kev tsheb kauj vab qhia meej 19.2mm axel kom tshem tawm 12mm los ntawm qag nrog 100mm nruab nrab ntawm rab rawg.

Tshuag 3/4 nti 10swg txhuas raj yog qhov haum zoo thiab muaj tshooj zoo hu ua Dave ntawm ebay (https://www.ebay.co.uk/str/aluminiumonline) muab thiab txiav nws kom ntev rau kuv ob peb phaus.

Tus actuator muaj 20mm bar nrog 6mm qhov yog li 3D luam tawm ib feem txuas cov raj txhuas mus rau 6mm steel bar thiab txij li lub zog yog 90% kev sib zog qee cov PLA / ABS yog qhov nyuaj.

Yog tias koj ua tus txheej txheem tso tawm sai sai tom qab qee yam zoo li no (https://www.amazon.co.uk/Sharplace-Quick-Release-Conversion-Adapter/dp/B079DCY344) yuav zam tsis tau rov tsim dua cov khoom no.

Lub khau raj tau tsim los kom haum rau hauv qhov raiser muab nrog kuv tus kws qhia Tacx tab sis tej zaum yuav haum rau ntau tus neeg sib tw zoo sib xws lossis koj tuaj yeem hloov kho TinkerCad cov ntaub ntawv kom haum rau koj qhov xav tau.

Kauj Ruam 4: Kho vajtse 2 - H -Choj

Cov L298N H choj pawg thawj coj uas muaj ntau hauv online tau tsim hauv 5V tus tswj hwm uas yog qhov zoo rau kev ua kom lub zog Arduino los ntawm 12V lub zog xa hluav taws xob xav tau rau tus ua haujlwm tawm. Hmoov tsis zoo Arduino Nano IoT pawg thawj coj yog 3.3V teeb liab li qhov xav tau rau cov qib kev hloov pauv (lossis tus optoisolator txij li cov cim qhia tsis yog ib qho nkaus xwb).

Cov ntaub ntawv tau tsim los lees txais cov txuas hluav taws xob feem ntau siv hauv LED teeb pom kev zoo. Kuv butchered USB txuas ntxiv ua kom nws muaj peev xwm txuas / txiav tawm Arduino lub taub hau chav yooj yim thiab thaum kuv paub tseeb tias yuav siv cov kab hluav taws xob rau lub zog thiab cov ntaub ntawv kab rau 3.3V teeb liab Kuv xav ncaj ncees qhia ntxiv qhov no raws li kuv xav tau ntxub ib tus neeg los kib lawv cov chaw nres nkoj USB lossis cov khoom siv los ntawm kev ntsaws lawv ua yuam kev!

Kauj Ruam 5: Kho Vajtse 3 Cov Khoom Siv Hluav Taws Xob (Arduino)

Cov ntaub ntawv rau Arduino OLED thiab qib kev hloov pauv logic muaj tus qauv 1/2 tig Garmin style mount rau sab nraub qaum kom tso nws kom ruaj ntseg rau lub tsheb kauj vab. Ib qho 'tawm sab xub ntiag' yuav tso cai rau chav nyob kom qaij lossis nce mus rau 'xoom' txoj haujlwm ntsuas qhov ntsuas lossis kab ntawm kab lus tsuas yog pib xoom thaum pib yuav yooj yim ntxiv.

Cov ntaub ntawv muaj qhov chaw rau daim nyias nyias khawm - qhov no yog siv los teeb tsa tus neeg caij tsheb thiab lub tsheb kauj vab hnyav. Koj tuaj yeem tsim qhov programmatically tshwj xeeb tshaj yog tias koj tsis qhia tus kws qhia nrog leej twg.

Nws yuav yog qhov zoo los siv hom 'phau ntawv'. Tej zaum nias ob lub nyees khawm tuaj yeem pib ua hom ntawv thiab tom qab ntawd cov nyees khawm tuaj yeem nce / txo qis. Kuv yuav ntxiv qhov no rau daim ntawv yuav tsum ua!
