Mawu Oyamba
Chikalatachi chili ndi malangizo owerengera NI 671X/672X/673X pazida za PCI/PXI/CompactPCI zotulutsa analogi (AO).
Chikalatachi sichikukambirana za njira zopangira mapulogalamu kapena kasinthidwe kawopanga. Dalaivala wa National Instruments DAQmx ali ndi chithandizo files omwe ali ndi malangizo enieni a compiler ndi mafotokozedwe atsatanetsatane a ntchito. Mutha kuwonjezera thandizo izi files mukakhazikitsa NI-DAQmx pakompyuta yoyeserera.
Zipangizo za AO ziyenera kusanjidwa pakanthawi kochepa monga momwe zimafotokozedwera ndi kuyeza kolondola kwa pulogalamu yanu. National Instruments imalimbikitsa kuti muzitha kuwerengera nthawi zonse kamodzi pachaka. Mutha kufupikitsa nthawiyi kukhala masiku 90 kapena miyezi isanu ndi umodzi.
Mapulogalamu
Kuwongolera kumafuna woyendetsa waposachedwa wa NI-DAQmx. NI-DAQmx imaphatikizapo mafoni apamwamba kwambiri kuti muchepetse ntchito yolemba mapulogalamu kuti azitha kuyendetsa zida. Dalaivala amathandizira zilankhulo zambiri zamapulogalamu, kuphatikiza LabVIEW, LabWindows ™/CVI ™ , icrosoft Visual C++, Microsoft Visual Basic, ndi Borland C++.
Zolemba
Ngati mukugwiritsa ntchito dalaivala wa NI-DAQmx, zikalata zotsatirazi ndizomwe mumagwiritsa ntchito polemba zofunikira zanu:
- NI-DAQmx C Reference Help imaphatikizapo zambiri zokhudzana ndi ntchito mu dalaivala.
- DAQ Quick Start Guide ya NI-DAQ 7.3 kapena mtsogolo imapereka malangizo oyika ndikusintha zida za NI-DAQ.
- Thandizo la NI-DAQmx limaphatikizapo zambiri pakupanga mapulogalamu omwe amagwiritsa ntchito oyendetsa NI-DAQmx.
Kuti mudziwe zambiri za chipangizo chomwe mukuchilinganiza, onani
Thandizo la Analog Output Series.
Zida Zoyesera
Chithunzi 1 chikuwonetsa zida zoyesera zomwe mukufuna kuti musamalire chipangizo chanu. Ma DMM enieni, ma calibrator, ndi ma counter afotokozedwa mu gawo la Calibration Process.
Chithunzi 1. Malumikizidwe a Calibration
Mukakonza ma calibration, National Instruments imalimbikitsa kuti mugwiritse ntchito zida zotsatirazi poyesa chipangizo cha AO:
- Calibrator-Fluke 5700A. Ngati chidacho sichikupezeka, gwiritsani ntchito voliyumu yolondola kwambiritage gwero lomwe lili pafupifupi 50 ppm lolondola pama board a 12- ndi 13-bit ndi 10 ppm pama board a 16-bit.
- DMM—NI 4070. Ngati chidacho sichikupezeka, gwiritsani ntchito DMM yamitundu yambiri ya 5.5 ndi kulondola kwa 40 ppm (0.004%).
- Kauntala—Hewlett-Packard 53131A. Ngati chidacho sichikupezeka, gwiritsani ntchito chowerengera cholondola mpaka 0.01%.
- Zingwe zowonjezera zamkuwa zotentha za EMF-Fluke 5440A-7002. Osagwiritsa ntchito zingwe zokhazikika za nthochi.
- DAQ chingwe—NI imalimbikitsa kugwiritsa ntchito zingwe zotetezedwa, monga SH68-68-EP yokhala ndi NI 671X/673X kapena SH68-C68-S yokhala ndi NI 672X.
- Chimodzi mwazinthu zotsatirazi za DAQ:
SCB-68—SCB-68 ndi chotchinga chotchinga cha I/O chokhala ndi zomangira 68 zolumikizira mosavuta ku zida za DAQ 68- kapena 100.
- CB-68LP/CB-68LPR/TBX-68—The CB-68LP, CB-68LPR, ndi TBX-68 ndi zipangizo zotsika mtengo zothetsa zokhala ndi zomangira 68 zolumikizira mosavuta ma sign a I/O ku 68-pini DAQ zipangizo.
Zolinga Zoyesa
Tsatirani malangizowa kuti muwongolere malumikizanidwe ndi miyeso yoyeserera pakuyesa:
- Sungani zolumikizira ku NI 671X/672X/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.
Njira ya Calibration
Gawoli limapereka malangizo otsimikizira ndikuwongolera chipangizo chanu.
Calibration Process Yathaview
Njira ya calibration ili ndi njira zinayi:
- Kukhazikitsa Koyamba-Konzani chipangizo chanu mu NI-DAQmx.
- Njira Yotsimikizira AO-Tsimikizirani momwe chipangizochi chikugwirira ntchito. Sitepe iyi imakupatsani mwayi wotsimikizira kuti chipangizocho chimagwira ntchito mkati mwazosankha zake chisanawunikenso.
- AO Adjustment Procedure-Chitani ma calibration akunja omwe amasintha ma calibration okhazikika a chipangizocho molingana ndi voliyumu yodziwika.tagndi gwero.
- Chitani chitsimikiziro china kuti muwonetsetse kuti chipangizochi chikugwira ntchito mkati mwazofotokozera pambuyo pa kusintha.Masitepewa akufotokozedwa mwatsatanetsatane m'magawo otsatirawa. Chifukwa kutsimikizira kwathunthu kwamitundu yonse yachidacho kungatenge nthawi, mungafune kutsimikizira zokhazo zomwe zingakusangalatseni.
Kupanga Koyamba
NI-DAQmx imangozindikira zida zonse za AO. Komabe, kuti dalaivala azitha kulumikizana ndi chipangizocho, chiyenera kukhazikitsidwa mu NI-DAQmx.
Kuti mukonze chipangizo mu NI-DAQmx, malizitsani izi:
- Ikani pulogalamu yoyendetsa NI-DAQmx.
- Zimitsani kompyuta yomwe ingagwire chipangizocho, ndikuyika chipangizocho pamalo omwe alipo.
- Yambitsani pakompyuta, ndikuyambitsa Measurement & Automation Explorer (MAX).
- Konzani chozindikiritsa chipangizocho ndikusankha Kudziyesa Kuti muwonetsetse kuti chipangizocho chikugwira ntchito bwino.
Zindikirani Chida chikakonzedwa ndi MAX, chimapatsidwa chozindikiritsa chipangizo. Aliyense
kuyimbira foni kumagwiritsa ntchito chozindikiritsa ichi kuti mudziwe kuti ndi chipangizo chiti cha DAQ chomwe chikuyenera kulinganiza.
Njira Yotsimikizira AO
Kutsimikizira kumatsimikizira momwe chipangizo cha DAQ chikukwaniritsira zofunikira zake. Pochita izi, mutha kuwona momwe chipangizo chanu chagwirira ntchito pakapita nthawi. Mutha kugwiritsa ntchito chidziwitsochi kukuthandizani kudziwa nthawi yoyenera yosinthira pulogalamu yanu.
Njira yotsimikizira imagawidwa m'magulu akuluakulu a chipangizocho. Pa nthawi yonse yotsimikizira, gwiritsani ntchito matebulo omwe ali mu gawo la AO Device Test Limits kuti muwone ngati chipangizo chanu chiyenera kusinthidwa.
Kutsimikizira kwa Analogi
Njira iyi imayang'ana momwe ntchito ya analogi imagwirira ntchito. Onani miyeso pogwiritsa ntchito njira iyi:
