Kauj Ruam 3: Cov Lus Qhia Txog…

Txuas cuam tshuam

Kev sib hloov ntawm lub ntsuas cua ntsuas yog ntsuas los ntawm kev ua haujlwm txuas cuam tshuam () (thiab tshem tawm cuam tshuam ()) hauv GPIO 12 (tus pin D6) ntawm Nodemcu (Nws muaj kev cuam tshuam cuam tshuam ntawm nws D0-D8 pins).

Kev cuam tshuam yog cov xwm txheej lossis cov xwm txheej uas ua rau lub microcontroller nres qhov kev ua tiav ntawm txoj haujlwm uas nws tau ua, ua haujlwm lwm txoj haujlwm ib ntus thiab rov qab los rau thawj txoj haujlwm.

Koj tuaj yeem nyeem cov ncauj lus kom ntxaws ntawm txoj haujlwm hauv qhov txuas rau kev qhia ntawm Arduino. Saib attachInterrupt ().

Syntax: attachInterrupt (tus pin, hu rov qab, cuam tshuam hom/hom);

pin = D6

kev ua haujlwm rov qab = rpm_anemometer - suav txhua qhov mem tes ntawm qhov sib txawv.

cuam tshuam hom/hom = RISING - cuam tshuam thaum tus pin nce ntawm qis mus rau siab.

Ntawm txhua qhov mem tes tsim los ntawm cov hlau nplaum hauv Hall sensor, tus pin nce ntawm qis mus rau siab thiab suav ua haujlwm tau qhib thiab suav cov mem tes hauv qhov sib txawv, thaum 25 vib nas this tsim. Thaum lub sijhawm tau tas sijhawm, lub txee raug txiav tawm (tshem tawm cuam tshuam ()) thiab niaj hnub suav qhov nrawm thaum txiav tawm.

Xam Cov Cua Ceev

Thaum nws tau txiav txim siab ntau npaum li cas kev hloov pauv lub ntsuas cua ntsuas hauv 25 vib nas this, peb suav qhov nrawm.

• RADIO yog ntsuas los ntawm qhov chaw nruab nrab ntawm lub ntsuas cua sov mus rau qhov kawg ntawm pob ping pong. Koj yuav tsum tau ntsuas koj li zoo heev - (saib hauv daim duab uas hais tias 10 cm).
• RPS (tig ib pliag) = tig / 25 vib nas this
• RPM (tig ib feeb) = RPS * 60
• OMEGA (nrawm nrawm - radians ib ob) = 2 * PI * RPS
• Tawm_Velocity (meters ib ob) = OMEGA * RADIO
• Tawm_Velocity_kmh (Km ib teev) = 3.6 * Linear_Velocity thiab qhov no yog qhov yuav xa mus rau ThingSpeak.

Nyeem cua txoj kev taw qhia

Txhawm rau nyeem txoj haujlwm ntawm lub cua vane txhawm rau txiav txim siab cov lus qhia ntawm cua qhov kev zov me nyuam xa cov cim qis thiab siab mus rau tus lej sib txuam nrog txhua qhov sib txuas ua ke ntawm qhov ntsuas A, B, C (muxABC matrix) thiab tos kom tau txais ntawm tus pin A0 qhov tshwm sim uas tuaj yeem yog qhov hluav taws xob nruab nrab ntawm 0 thiab 3.3V. Kev sib txuas ua ke tau qhia hauv daim duab.

Piv txwv li, thaum C = 0 (qis), B = 0 (qis), A = 0 (qis) tus lej sib npaug muab nws cov ntaub ntawv ntawm tus pin 0 thiab xa cov teeb liab mus rau A0 uas tau nyeem los ntawm Nodemcu; yog C = 0 (qis), B = 0 (qis), A = 1 (siab) tus lej sib npaug yuav xa koj cov ntaub ntawv ntawm tus pin 1 thiab ntxiv rau, kom txog thaum nyeem ntawm 8 raws tiav.

Raws li lub teeb liab yog analog, qhov program hloov pauv mus rau digital (0 lossis 1), yog tias qhov hluav taws xob tsawg dua lossis sib npaug rau 1.3V lub teeb liab yog 0; yog tias nws ntau dua 1.3V lub teeb liab yog 1. Tus nqi 1.3V yog kev xav thiab rau kuv, nws ua haujlwm tau zoo heev. Muaj ib txwm me me ntawm qhov tam sim no thiab qhov no tiv thaiv tias tsis muaj qhov tsis raug qhov tseeb.

Cov ntaub ntawv no tau muab khaws cia rau hauv tus lej vector [8] uas yuav muab piv nrog qhov chaw nyob raws li lub koob. Saib cov lej hauv daim duab. Piv txwv li, yog tias qhov vector tau txais yog [0, 0, 1, 0, 0, 0, 0, 0, 0, 0] nws qhia hauv matrix cov lus qhia E thiab sib haum rau lub kaum sab xis ntawm 90 degrees; yog [0, 0, 0, 0, 0, 0, 1, 1] qhia hauv matrix WNW qhov chaw nyob thiab sib haum rau lub kaum sab xis ntawm 292.5 degrees. N sib haum rau [1, 0, 0, 0, 0, 0, 0, 0, 0, 0] thiab lub kaum sab xis 0 degrees.

Dab tsi yuav xa mus rau ThingSpeak yog nyob ntawm lub kaum sab xis vim nws tsuas lees txais tus lej.

Kauj ruam 4: Kev sib txuas lus

Yuav xa cov ntaub ntawv mus rau ThingSpeak li cas

Muaj nuj nqi yam khoom siv hais lus () yog lub luag haujlwm xa cov ntaub ntawv.
