Qhov no yog txhawm rau hloov tus tswv xeev rau kev txwv kev nrawm ntawm lub tshuab roj av. Qhov txwv RPM no tuaj yeem hloov mus rau 3 qhov sib txawv ntawm qhov yoov. Kuv tau teeb tsa qhov no ntawm ib lub tog raj kheej, Briggs thiab Stratton cav thiab siv Arduino mega thiab lub vijtsam LCD. Yog tias koj yuav tsum tau ua haujlwm nrog lub rooj tsav xwm me dua koj tuaj yeem tsuas yog qhia tag nrho cov ntaub ntawv nrog cov xwm txheej teeb pom kev zoo thiab cov saib hauv qab

ib feem tseem ceeb ntawm txoj haujlwm no yog nrhiav lub xaim hluav taws xob qis ntawm lub cav uas koj tuaj yeem kaw nws nrog. Koj tuaj yeem txuas qhov xaim loj uas mus los ntawm lub kauj mus rau lub ntsaws ntsaws, tab sis qhov hluav taws xob siab tuaj yeem hla hla kev sib cuag. Peb tuaj yeem tswj cov xov hluav taws xob qis mus rau lub kauj thiab qhov ntsuas qhov hluav taws xob. 6v relay yuav tuaj yeem ua qhov no, thiab peb tuaj yeem tswj qhov kev xa me me nrog arduino.

Thawj daim duab yog los ntawm 90's lub tshuab txiav nyom, nws yuav kaw yog tias koj txuas cov hlau ntsuab rau hauv av.

Daim duab thib ob yog los ntawm tus tshiab briggs thiab lub tshuab stratton, nws yuav kaw yog tias koj tsaws cov hlau liab/dub.

Kuv tsis tuaj yeem muab cov lus qhia rau txhua lub cav yog li koj yuav tau ua qee qhov kev sim. Koj tuaj yeem pom cov lus qhia zoo dua yog tias koj saib 'tua tua' rau koj lub cev tshwj xeeb. Nco ntsoov tias ib qho ntawm koj cov pins ntawm kev xa tawm yog ON thaum lub zog xa tawm, thiab lwm qhov yog OFF thaum lub zog xa tawm.

Tam sim no ntws los ntawm cov xaim yuav ua rau muaj qhov sib nqus sib nqus, thiab koj tuaj yeem siv qhov hloov pauv sib nqus los tsim qhov sib nqus ntawm qhov tam sim no los ntawm qhov sib txawv, cais cov hlau. Qhov no yog lub hauv paus ntsiab lus uas tiv thaiv cov hlua hluav taws xob, hloov pauv, thiab cov wireless them ua haujlwm. Peb tuaj yeem siv qhov txiaj ntsig no los nyeem qhov nrawm ntawm lub cav yog tias peb qhwv lub voj hlau nyob ib puag ncig lub xov hluav taws xob.

Nrog lub cav ua haujlwm, Kuv pom tias 2 lub voj voos ntawm ib puag ncig lub qhov hluav taws xob txuas hluav taws xob tau tsim cov mem tes txog +/- 15-20v. Peb tuaj yeem siv tus tiv thaiv thiab diode los thaiv qhov tsis zoo thiab txo qhov hluav taws xob. Kuv siv cov mem tes no los tswj MOSFET transistor, thiab siv cov transistor tso tawm los tswj tus lej digital ntawm Arduino.

Lub cav tsim hluav taws xob ntau qhov hluav taws xob, thiab lub voj nyob ib puag ncig lub qhov hluav taws xob txuas hluav taws xob kuj tseem tuaj yeem tsim hluav taws xob txaus kom kib Arduino, yog li kuv pom zoo ntsuas qhov ntsuas hluav taws xob no los ntawm kev txuas lub ntsuas hluav taws xob mus rau MOSFET. txuas ib lub xov hlau nyob ib puag ncig lub txim hluav taws xob ncaj qha rau Arduino yuav tawg nws.

Ib qho kev poob qis ntawm cov kab ke no yog tias thaum kev xa tawm txiav lub txim hluav taws xob, Arduino tsis tuaj yeem tau txais kev nyeem ntawv los ntawm lub ntsaws ntsaws kom pom tias lub cav tau nrawm npaum li cas. Qhov haujlwm no tua lub txim hluav taws xob thaum lub cav nrawm dhau, thiab tom qab ntawv nyeem tam sim ntawd 0 rpm qhov rov ua dua tom ntej thiab tig rov qab. Feem ntau lwm qhov haujlwm Arduino-tachometer siv lub ntsej muag ua kom pom tseeb. Ntawm qhov one tes, cov tshuab siv hluav taws xob tsis xav tau ntxiv ib qho txav mus rau lub cav. Ntawm qhov tod tes, tsis muaj qhov teeb meem inductive thaum lub kaw hluav taws kaw/txiav txim/ua tsis raug/txiav tawm

ntu no yog nyob ntawm yeem tab sis nws muaj txiaj ntsig zoo nkauj

nws tsuas yog qhov faib hluav taws xob uas siv qhov hloov pauv kom hla qee qhov resistors nyob ntawm txoj haujlwm. Qhov txwv rpm tiag tiag yog txiav txim siab hauv cov cai, qhov no tsuas yog tso cai rau koj hloov chaw ntawm yoov.

Kev xa tawm yog qhov hloov pauv uas qhib lossis tua thaum nws tau txais lub zog. Koj tuaj yeem siv qhov me me tam sim no (zoo li 40mA digital arduino tus pin) los hloov qhov loj dua (lub cav lub tshuab hluav taws xob)
