Kev Tsim Cov Hluav Taws Xob Hluav Taws Xob rau Kev Sau Se Cov Hluav Taws Xob
Cov Khoom Kho Vajtse ntawm Kev Sau Se Cov Hluav Taws Xob
Vim tias cov sensors sib txawv muaj cov zis sib txawv, tab sis thaum kawg yuav tsum hloov mus rau. 0 ~ 10V voltage tus nqi, thiaj li ua tau raws li A / D converter hloov dua siab tshiab yuav tsum. Txhua lub sensor yog li ntawd yuav tsum muaj kev sib hloov sib txawv thiab ua kom nrov nrov. Tom qab hloov dua siab tshiab ntawm cov roj hluav taws xob los ntawm ntau cov channel analog hloov mus rau tib A / D converter rau hloov dua siab tshiab. Thiab tom qab ntawd dhau los ntawm FPGA rau kev tsim cov ntaub ntawv thiab tso saib cov zis
PN hlws ris ntsuas kub ntsuas
Raws li PN kev sib tshuam nrog kev hloov pauv kub yog qhov ntsuas hluav taws xob, qhov kub tau nce li 1 ° C. PN kev sib tshuam zoo conduction voltage poob los ntawm 1mV. Tab sis ntawm 0 ℃ thaum cov zis hluav taws xob xav tau OV, nws yuav tsum txuas nrog PN hlws ris PN kev sib tshuam ib leeg caj npab tsis sib xyaw DC choj thiab qhov tso zis hluav taws xob tau nthuav dav rau 0 ~ 10v ntau kom xa A / D converter Circuit Court schematic daim duab (2) :
PT100 ($ 5.8752) thaum tshav kub kub ua hauj lwm ntsuas kub txoj cai ntsuas kho vajtse Circuit Court
Raws li PT100 thermal tsis kam nrog kev hloov kub yog qhov ntsuas tiv thaiv, thaum qhov kub nce ntxiv qhov ua haujlwm nce. Yog li no, lub thermal tiv thaiv yuav tsum txuas nrog rau hauv ib txhais caj npab DC choj, qhov thev naus laus zis hloov pauv mus rau qhov ntsuas hluav taws xob hloov. Thiab tom qab ntawd lub teeb liab voltage amplified rau 0 ~ 10V ntau kom xa A / D hloov Circuit Court.
Thermocouple ntsuas kub ntsuas txoj ntsiab cai kho vajtse Circuit Court
Thermocouple cov khoom tso tawm yog qhov ntsuas kub-raws qhov ntsuas hluav taws xob, nws yuav tsum tau txuas nrog cov hluav taws xob sib tshuam txias kom ua haujlwm kom raug, thiab nws cov khoom tawm yuav tsum hloov mus rau 0 ~ 10V ntau A / D hloov kho Circuit Court. Daim duab Circuit Court qhia hauv Daim Duab 3:
Software Tsim Kev Kub Ntxhov Sib Sau Cov Ntaus
Kub qhov txheej txheem tsim cov software tau muab faib ua ib qho kev pab cuam ib leeg thiab F tshaj Qhov kev tsim qauv, ib qho kev pab cuam ib qho kev sau ua ib hom lus sau ua ke kom ua tiav qhov kev tswj ntawm sab nraud. FPGA siv cov lus VHDL kom ua tiav cov ntaub ntawv ua thiab ntsuas qhov ntsuas kub tawm. Cov txheej txheem kub kom ua tiav tuaj yeem ua tiav PN kev sib tshuam (20 ~ 100 ℃), tiv thaiv thermal (PT100) (0 ~ 800 ℃), cov txheej txheem ntsuas kub ntawm lub ntsuas kub. Txhawm rau kom ua tiav qhov ntsuas ntau qhov sib txawv, ntsuas ntsuas kom pom tseeb thiab cov kev xav tau ntawm cov sij hawm sib txawv. Tus qauv siv EDA ua ib qhov kev tsim kho, nrog SCM tswj ua rau tag nrho cov qauv nrog cov tswv yim tsim dua tshiab. Kev siv 12 ADC analog-digital converter, ua cov ntsuas ntsuas tau zoo dua. Kev ua cov ntaub ntawv siv teb-programmable rooj vag array PFGA (EPIK30QC208-3), nws cov kev ua haujlwm siab ua haujlwm ceev ua rau lub kaw lus nrawm dua thiab ntau dua qhov lus teb.
Hauv daim ntawv no, qhov kev ntsuas kub kom tau raws li MCU thiab EDA yog tsim, uas tuaj yeem paub qhov ntsuas kub ntawm PN hlws ris, thermal tsis kam (PT100), thermocouple (npib tsib xee roj silicon K) Ntawm ntsuas ntau, txawv ntsuas qhov tseeb thiab cov kev xav tau ntawm txawv sijhawm. Tus qauv siv EDA ua ib qhov kev tsim kho, nrog SCM tswj, ua tus qauv tsim nrog cov tswv yim tsim dua tshiab.
