NATIONAL INSTRUMENTS PCI-6731 Analogi Output Board
Zambiri Zogulitsa: PCI-6731
PCI-6731 ndi chipangizo cha PCI/PXI/CompactPCI Analog Output (AO) chopangidwa ndi National Instruments (NI). Ndi gawo la mndandanda wa NI 671X/673X, womwe umaphatikizapo mitundu ya NI 6711, NI 6713, NI 6715, NI 6731, ndi NI 6733. Chipangizochi chimalola kuti voliyumu ikhale yolondola kwambiritage linanena bungwe ndipo amagwiritsidwa ntchito kwambiri pamakina oyezera pa PC.
Kayendetsedwe ka Calibration
Bukhuli lili ndi malangizo owongolera zida za NI 671X/673X pogwiritsa ntchito pulogalamu ya Traditional NI-DAQ. Kuwongolera ndikofunikira kuti muwonetsetse kuti miyeso yochitidwa ndi chipangizocho ndi yolondola. Kuchuluka kwa ma calibration kumadalira muyeso wa ntchito yanu, ndi NI ikulimbikitsa kuwongolera kwathunthu kamodzi pachaka. Komabe, mutha kusankha kuwongolera pafupipafupi, monga masiku 90 aliwonse kapena miyezi isanu ndi umodzi iliyonse, kutengera zomwe mukufuna.
Zosankha za Calibration: Internal Versus External
Zipangizo za NI 671X/673X zimapereka njira ziwiri zosinthira: mkati (kudziyesa nokha) ndi kuwongolera kunja.
- Kuwongolera Kwamkati: Kuwongolera kwamkati ndi njira yodzipangira yokha yomwe imachitidwa ndi chipangizocho. Njirayi imasintha ma calibration constants omwe amasungidwa mu chipangizocho kuti azikhala olondola.
- External Calibration: Kuwongolera kwakunja kumafuna zida zowonjezera, kuphatikizapo calibrator ndi high-precision Digital Multimeter (DMM). Pakuyesa kwakunja, DMM imapereka ndikuwerenga voltages kuchokera ku chipangizo. Zosintha zimapangidwira pazosintha zosinthira zida kuti zitsimikizire kuti voltagimakwaniritsa zofunikira za chipangizocho. Zosintha zatsopano zimasungidwa mu EEPROM ya chipangizocho. Kuwongolera kwakunja kumapereka mndandanda wa ma calibration constants omwe angagwiritsidwe ntchito kubweza zolakwika za muyeso.
Zida ndi Zofunikira Zina Zoyeserera
Kuti muyese chipangizo cha NI 671X/673X, zida zotsatirazi ndi zoyeserera zimafunika:
- Zida Zoyesera: Calibrator ndi olondola kwambiri Digital Multimeter (DMM) ndizofunikira. NI imalimbikitsa kugwiritsa ntchito Agilent 3458A DMM kapena mulingo woloweza m'malo womwe umakwaniritsa zofunikira zolondola. DMM ikuyenera kukhala yolondola zosachepera 40 ppm (0.004%) pazida 12-bit ndi 10 ppm (0.001%) pazida 16-bit. Zida zolumikizira mwamakonda, monga cholumikizira cha NI CB-68 ndi zingwe zoyenera, zithanso kufunikira kuti mupeze cholumikizira cha I/O cha chipangizocho.
- Zoyeserera: Buku la ogwiritsa ntchito limapereka malangizo othandizira kukhathamiritsa maulumikizidwe ndi miyeso yoyeserera panthawi yoyeserera. Malangizowa amatsimikizira zotsatira zolondola komanso zodalirika zowongolera.
Mapulogalamu
Kuti muyesere, makina owerengera ayenera kukhala ndi dalaivala yoyenera ya chipangizocho. Pazida za NI 671X/673X, pulogalamu ya Traditional NI-DAQ ndiyofunika. Ndikofunikira kukhazikitsa NI-DAQ kuchokera ku NI webtsamba (ni.com/downloads). NI-DAQ imathandizira zilankhulo zosiyanasiyana zamapulogalamu, kuphatikiza LabVIEW, LabWindowsTM/CVITM, Microsoft Visual C++, Microsoft Visual Basic, ndi Borland C++. Mukakhazikitsa, yikani chithandizo cha chilankhulo chomwe mukufuna kugwiritsa ntchito pa pulogalamu yanu. Potsatira malangizo omwe aperekedwa ndikugwiritsa ntchito zida ndi mapulogalamu omwe akulimbikitsidwa, mutha kuyesa bwino chipangizo chanu cha NI 671X/673X kuti musunge miyeso yolondola pakugwiritsa ntchito kwanu.

Zosankha za Calibration: Internal Versus External
NI 671X/673X ili ndi njira ziwiri zosinthira: mkati, kapena kudziyesa nokha, komanso kuwongolera kwakunja.
Kuwongolera kwamkati
Kuwongolera kwamkati ndi njira yosavuta yosinthira yomwe sidalira miyezo yakunja. Mwanjira iyi, zosinthira zowongolera zida zimasinthidwa molingana ndi voliyumu yolondola kwambiritagndi gwero la NI 671X/673X. Kuwongolera kotereku kumagwiritsidwa ntchito pambuyo poti chipangizocho chasinthidwa molingana ndi muyezo wakunja. Komabe, zosintha zakunja monga kutentha zimathabe kukhudza miyeso. Zosintha zatsopano za calibration zimatanthauzidwa molingana ndi ma calibration constants omwe amapangidwa panthawi yachitsulo chakunja, kuonetsetsa kuti miyeso ikhoza kutsatiridwa kuzinthu zakunja. M'malo mwake, kuwerengetsa kwamkati kumafanana ndi ntchito ya auto-zero yomwe imapezeka pa digito multimeter (DMM).
Kuwongolera Kwakunja
Kuwongolera kwakunja kumafuna kugwiritsa ntchito calibrator ndi DMM yolondola kwambiri. Pakuyesa kwakunja, DMM imapereka ndikuwerenga voltages kuchokera ku chipangizo. Zosintha zimapangidwira pazosintha zosinthira zida kuti zitsimikizire kuti voltages ali mkati mwazofunikira za chipangizocho. Zosintha zatsopano zimasungidwa mu chipangizo cha EEPROM. Pambuyo posintha ma calibration okhazikika, ma voliyumu olondola kwambiritage gwero pa chipangizo ndi kusintha. Kuwongolera kwakunja kumapereka magawo osinthika omwe mungagwiritse ntchito kubweza zolakwika mumiyeso yotengedwa ndi NI 671X/673X.
Zida ndi Zofunikira Zina Zoyeserera
Gawoli likufotokoza zida, zoyeserera, zolembedwa, ndi mapulogalamu omwe muyenera kuwongolera NI 671X/673X.
Zida Zoyesera
Kuti muyese chipangizo cha NI 671X/673X, mufunika calibrator ndi multimeter ya digito (DMM). NI imalimbikitsa kugwiritsa ntchito zida zoyeserera izi: -
- Calibrator-Fluke 5700A
- DMM-Agilent (HP) 3458A
Ngati mulibe Agilent 3458A DMM, gwiritsani ntchito mfundo zolondola kuti musankhe mulingo woloweza m'malo. Kuti muyese chipangizo cha NI 671X/673X, mufunika DMM yolondola kwambiri yomwe ili yolondola 40 ppm (0.004%). Calibrator iyenera kukhala yolondola osachepera 50 ppm (0.005%) pazida 12-bit ndi 10 ppm (0.001%) pazida 16-bit.
Ngati mulibe zida zolumikizira makonda, mungafunike cholumikizira monga NI CB-68 ndi chingwe monga SH68-68-EP. Pa NI 6715, gwiritsani ntchito chingwe cha SHC68-68-EP. Zidazi zimakupatsani mwayi wofikira mapini pawokha pa cholumikizira cha 68-pin I/O.
Zoyeserera
Tsatirani malangizowa kuti muwongolere malumikizanidwe ndi miyeso yoyeserera pakuyesa:
- Sungani zolumikizira ku NI 671X/673X zazifupi. Zingwe zazitali ndi mawaya zimakhala ngati tinyanga, kunyamula phokoso lowonjezera, lomwe lingakhudze miyeso.
- Gwiritsani ntchito mawaya a mkuwa otetezedwa polumikiza zingwe zonse pa chipangizocho.
- Gwiritsani ntchito mawaya opotoka kuti muchepetse phokoso ndi kutentha.
- Sungani kutentha kwapakati pa 18 ndi 28 ° C. Kuti mugwiritse ntchito gawoli pa kutentha kwina kunja kwa mulingo uwu, yang'anirani chipangizocho kutentha komweko.
- Sungani chinyezi chocheperako 80%.
- Lolani nthawi yotentha ya mphindi 15 kuti muwonetsetse kuti miyeso yozungulira ili pa kutentha kokhazikika.
Mapulogalamu
Chifukwa NI 671X/673X ndi chipangizo choyezera pa PC, muyenera kukhala ndi dalaivala yoyenera yoyikira mu makina oyesa musanayese kuwongolera. Pakuwongolera uku, mufunika Traditional NI-DAQ kuyika pakompyuta yoyezera. NI-DAQ, yomwe imakonza ndikuwongolera NI 671X/673X, ikupezeka pa ni.com/downloads.
NI-DAQ imathandizira zilankhulo zingapo zamapulogalamu, kuphatikiza LabVIEW, LabWindows™/CVI™, Microsoft Visual C++, Microsoft Visual Basic, ndi Borland C++. Mukayika dalaivala, mumangofunika kukhazikitsa chithandizo chachilankhulo chomwe mukufuna kugwiritsa ntchito.
Mufunikanso makope a ni671xCal.dll, ni671xCal.lib, ndi ni671xCal.h files.
DLL imapereka magwiridwe antchito omwe sakhala mu NI-DAQ, kuphatikiza kuthekera koteteza ma calibration constants, kusinthiratu tsiku loyeserera, ndikulembera kudera loyeserera fakitale. Mutha kupeza magwiridwe antchito mu DLL iyi kudzera pagulu lililonse la 32-bit. Malo oyezera fakitale ndi tsiku loyezera ziyenera kusinthidwa ndi labotale ya metrology kapena malo ena omwe amasunga miyezo yolondola.
Kukonza NI 671X/673X
NI 671X/673X iyenera kukonzedwa mu NI-DAQ, yomwe imazindikira chipangizocho. Njira zotsatirazi zikufotokozera mwachidule momwe mungasinthire chipangizocho mu NI-DAQ. Onani ku NI 671X/673X User Manual kuti mudziwe zambiri za kukhazikitsa. Mutha kukhazikitsa bukuli mukakhazikitsa NI-DAQ.
