Yav dhau los: Cov Tub Ntxhais Kawm Ntawv yog lub ntiaj teb feem ntau tsim muaj kev sib tw kev tsim txuj ci engineering uas cov tub ntxhais kawm los ntawm ntau lub tsev kawm ntawv sib tw los tsim, tsim, tsim thiab sib tw ua qauv tsheb hom. Cov tsheb no muaj kev ua tau zoo raws li kev nrawm, nres thiab sib tsoo. Thaum sib tw lawv raug sim hauv cov xwm txheej zoo li piv txwv li kev tsim qauv, tus nqi thiab kev nyob ruaj khov, kev nthuav qhia kev lag luam thiab hauv kev sib tw muaj zog uas suav nrog kev nrawm dua, kev ua siab ntev, kev sib tw khiav, lub ncoo nplua thiab kev lag luam roj. Kev loj hlob xav tau los xyaum ua cov txuj ci uas tau qhia hauv ntau yam kev kawm ntawm Polytechnic ntawm Leiria tau coj cov tub ntxhais kawm los nqis peev hauv Formula Student sib tw. Pab pawg (FSIPLeiria) muaj cov tswv cuab los ntawm ntau thaj chaw ntawm kev kawm, los ntawm cov tub ntxhais kawm engineering mus rau kev tswj hwm thiab kev lag luam. Yog xav paub ntxiv txog pab pawg mus ntsib peb lub vev xaib tshiab:

Lub Hom Phiaj:

Lub hom phiaj tseem ceeb ntawm lub log tsheb kom tau txais lub ntsuas cua sov, raws li nws lub npe qhia, yog txhawm rau ntsuas qhov kub ntawm cov log tsheb sib tw. Rau lub hom phiaj ntawd, tau siv lub ntsuas hluav taws xob liab nrog 64 ntsuas ntsuas (MLX90620). Cov ntaub ntawv ntsuas kub tau xa mus rau lub microcontroller nrog CAN transceiver uas xa cov ntaub ntawv xav tau mus rau CAN npav ntawm lub tsheb.

Khoom siv

• Kub ntsuas MLX90620;

• Transceiver SPI-CAN MCP2515;

• Transceiver CAN MCP2551;

• Tus tswj hluav taws xob 12V-5V MCP1755_5;

• Tus tswj hluav taws xob 12V-3V MCP1755_3;

• Standalone Atmega328P microcontroller.

Lub hauv paus tseem ceeb ntawm lub tsheb ua haujlwm nrog kev nrawm ntawm kwv yees li 12V. Lub rooj tsavxwm tau tsim los ua haujlwm nrog 5V, yog li ntawd, yuav tsum siv lub ntsuas hluav taws xob (12V-5V). Qhov ntsuas qhov ntsuas qhov siab tshaj plaws yog 3V yog li lwm qhov ntsuas hluav taws xob (12V-3V) tau siv. Qhov cov ntaub ntawv matrix (16x4) muab los ntawm lub ntsuas qhov ntsuas tau txais thiab hloov pauv mus rau 3 lub log loj hauv cheeb tsam (sab hauv, nruab nrab thiab sab nraud). Tom qab ntawd, peb qhov hloov pauv raug xa los ntawm SPI mus rau tus xa xov SPI-CAN MCP2515 uas xa cov ntaub ntawv mus rau tus xa xov xwm CAN MCP2551 uas sau qhov hloov pauv hauv lub tsheb CAN npav.

Txhawm rau tshuaj xyuas yog tias txhua yam ua haujlwm raws li phiaj xwm, ua ntej tsim PCB, cov phiaj xwm tau ua tiav ntawm lub khob cij. Daim duab tsis qhia, tab sis txhawm rau sim lub tsheb 12V lub roj teeb tau siv lub zog.

Kev ntim khoom ntawm cov khoom yuav tsum tau ua tib zoo npaj vim tias tus qauv yuav raug txuas nrog ze lub log yog li nws yuav tsum me me li sai tau. Qhov txiaj ntsig kawg tau qhia hauv daim duab 3 thiab nws raws li qhov ntev hauv qab no 48x12 mm.
