I-DATALOGGERINC SQ2010 Umhlahlandlela Womsebenzisi Wohlelo Lokungena Kwedatha Ephathekayo
Amasistimu wokuqopha idatha ephathekayo angamathuluzi abalulekile asetshenziswa ezimbonini ezahlukahlukene ukuqapha nokuqopha izinga lokushisa, voltage, amanani amanje, namanye Asetshenziselwa ukuxazulula izinkinga, ukulawula ikhwalithi, ukuqapha inqubo, nokuqoqwa kwedatha, lawa madivayisi ahlangene adinga ukukhethwa ngokucophelela. Lo mhlahlandlela unikeza imibuzo ebalulekile okufanele icatshangelwe lapho ukhetha isistimu yokuloga idatha efanelekile yezidingo zakho ezithile.
- Inombolo nohlobo lokokufaka: Zingaki iziteshi ozidingayo, futhi hlobo luni lwezinzwa ozozisebenzisa?

- Ukulinganisa: Isistimu izodinga ukulinganiswa kangaki?
Ngokucabangela lezi zici, ungakhetha a isistimu yokungena idatha ephathekayo ehlangabezana nezidingo zakho ezithile kanye nezicelo.
Imibuzo eyi-12 yokukhetha Uhlelo Lokungena Kwedatha Ephathwayo
Nsuku zonke, amakhulu ezingcingo nama-imeyili angena kubasabalalisi bedatha yedatha kanye nabahlanganisi bezinhlelo bebuza: "Imuphi umkhiqizo olungele isicelo sami?" Kungakhathaliseki ukuthi unguchwepheshe ohlela iphrojekthi yakho yakamuva noma ungumthengi ogcwalisa isicelo, inani elikhulu labakhiqizi namamodeli aloku idatha lingaba likhulu kakhulu. Ukwenza ukukhetha kwakho kube lula, nansi imibuzo eyishumi engakusiza ngenqubo yesinqumo:
1. Yiziphi Izidingo Zakho Zokungena Kwedatha?
Ukuloga kwedatha okujwayelekile kanye nezinhlelo zokusebenza Zokutholwa Kwedatha (DAQ) zigxile ekuqoqeni idatha ukuze kwenziwe isinqumo mayelana nokusebenza kahle, ukugcinwa kwesikhathi, noma i-R&D. Lawa masistimu anezinhlelo eziguquguqukayo namakhono okuxhumana, futhi afaka amasistimu aphathekayo anikwa amandla yibhethri noma amandla angaphandle.
2. Yini Edingekayo Sample Rate?
Umbuzo obalulekile okufanele uzibuze wona ukuthi udinga kangaki ukurekhoda isilinganiso (okungukuthi, i-logger's sampisilinganiso se-ling). Iningi labagawuli bedatha lirekhoda idatha ngamanani ashesha njengo-1Hz (kanye ngomzuzwana) noma ahamba kancane (kanye ngehora noma izikhathi ezimbalwa ngosuku). Amasistimu okuthola idatha angakwazi sample ngamakhulu noma izinkulungwane zezikhathi ngomzuzwana kodwa zidinga amandla engeziwe futhi zibiza kakhulu. Inani eliphakeme kakhulu lama-sampisilinganiso se-ling (umkhawulokudonsa) siyisici esibalulekile kuzo zonke izindleko zesistimu. A ephakeme sampI-le rate ithwebula izinguquko ezishesha kakhulu kusignali kodwa uma inani elilinganisiwe lishintsha kancane kuphela, ngokwesiboneloampizinga lokushisa lethangi elikhulu lamanzi noma ichibi, sampi-ling kanye ngesekhondi ikhiqiza kuphela idatha eningi engafuneki.
3. Mangaki Okokufaka Owadingayo?
Ingabe udinga nje ukubhala inani elilodwa lokulinganisa (elifana nezinga lokushisa) noma izinhlobo ezimbalwa zamanani okulinganisa (amanje kanye nevolumutage)? Amanye amamodeli adizayinelwe ukukala isilinganiso esisodwa, kuyilapho amaloga afaka izinto eziningi ahlanganisa amamodeli okuqapha i-AC vol.tage/yamanje, DC voltage/current, noma izinga lokushisa & nomswakama. Abagawuli bedatha abafakiwe jikelele zenzelwe ukurekhoda kusukela cishe kunoma iyiphi inzwa yokulinganisa ngokomzimba. Abagawuli bedatha bayatholakala futhi ekucushweni okunwebekayo okukwazi ukuphatha noma yikuphi kusuka kokukodwa kuya kwamakhulu okokufaka.
4. Hlobo Luni Lwezinzwa Ozolidinga?
Ukwazi uhlobo lwenzwa yakho kubalulekile uma ukhetha isistimu yokutholwa kwedatha. Lezi zinhlelo ziwusizo cishe kuyo yonke imboni, okuhlanganisa ukudla nesiphuzo, isayensi yempilo, kanye nokukhiqiza. Isizathu esivame kakhulu sokudinga uhlelo lokuloga idatha ukuqapha nokurekhoda izinga lokushisa usebenzisa ama-thermo-couples, ama-RTD noma ama-thermistors. Ezinye izinketho ezikhona zifaka i-current/voltagIzinzwa ze-e zokusetshenziswa kukagesi, izinzwa zokucindezela koketshezi noma amagesi, ama-flowmeters, okokufaka kwedijithali ukuqapha amaswishi noma ama-relay, izixhumanisi ze-serial communications ezifana ne-RS232, RS485 noma i-SDI-12 yokuqapha imvelo, noma ukuxhumana ne-MODBUS noma CAN amadivaysi asekelwe namasistimu. Ukwazi izinhlobo zezinzwa ezizosetshenziswa kubalulekile njengoba kukhomba uhlobo lwesimo sesignali esizodingeka - kungaba ku-logger noma ngaphandle.
5. Ingakanani Inkumbulo Eyidingayo Umgawuli?
Cabangela ukuthi uzodinga isikhala esingakanani sokulondoloza. Kuye ngohlelo lwakho lokusebenza, ungase ufune ukuthwebula kuphela idatha yemizuzu embalwa, inani lezinyanga ezimbalwa, noma ukuqhubeka uqaphe futhi ulondoloze yonke idatha. Kuya ngesiqophi sedatha, kungase kube nomkhawulo wememori yangaphakathi, noma lowo ologa anganikeza inketho yokusebenzisa imemori yangaphandle njengememori ye-USB.
6. Ingabe Uzodinga Amandla Alamu?
Zibuze ukuthi ingabe udinga ukuthola i-alamu uma inani lakho lokulinganisa liphuma ngaphandle kwebanga elicacisiwe lamanani. Uma kunjalo, ufuna ukwaziswa kanjani? Cabangela womabili ama-alamu endawo atholakala kumasistimu anomphumela wedijithali noma odluliswayo anganikeza isixwayiso nge-alamu ye-LED noma ezwakalayo noma izinketho ezithuthuke kakhulu zesaziso esikude esitholakala kumasistimu axhumeke kunethiwekhi anganikeza ama-alamu ngomlayezo wombhalo we-SMS, i-imeyili, ngisho nezaziso zekholi yezwi!
7. Uhlela kuphi ukufaka Uhlelo?
Kukhona amasistimu wokuloga idatha adizayinelwe ukufakwa okugxilile kanye namanye ezinhlelo zokusebenza eziphathwayo. Uma uhlelo ludinga ukuphatheka, usayizi, isisindo kanye nomthombo wamandla kuzoba izinto ezibalulekile. Lapho ucabangela ukuthi i-logger izosetshenziswa kanjani, zibuze le mibuzo:
- Izosebenza kanjani isistimu? Ibhethri, i-adaptha ye-AC, iphaneli yelanga, njll.
- Ingabe idinga ukuvikelwa kumswakama nokungcola?
- Ingabe isistimu idinga ukuzimela ngokuphelele ukuze isetshenziswe ngaphandle noma endaweni eyingozi? Ingabe izodinga a I-NEMA evalekile elinganiselwe?
Ngaphambi kokubheka izinketho zokuxhumana, qala, nquma ukuthi ungathanda ukuyibuyisa kanjani idatha. Ingabe uhlela ukuletha idivayisi ku-PC yasehhovisi ukuze ulande idatha, noma ufuna isistimu ukuyilanda ku-PC yakho ukude? Ukuxhumana nohlelo lokungena idatha ye viewukufaka nokulanda idatha kungenziwa ngezindlela eziningi ezahlukene ezihlanganisa:
- I-Serial RS-232/RS-485 uxhumano lwesixhumi esibonakalayo sezinhlelo zefa
- Isixhumi esibonakalayo se-USB
- Uxhumano lwenethiwekhi ye-Ethernet
- Isixhumanisi esibonakalayo esingenantambo esifaka i-Wi-Fi, i-Bluetooth, nezixhumanisi zerediyo zokuphathelene
- Imodemu yeselula yezindawo ezikude lapho uxhumano lwenethiwekhi lungatholakali
- Imodemu yesathelayithi - yezindawo ezikude kakhulu ezingenakho ukufakwa kwamaselula
9. Iyiphi Isofthiwe Edingekayo?
Yebo, idivayisi izodinga isofthiwe yokucushwa ukuze kumiswe okokufaka, sample rate, ama-alamu, njll. Uzodinga nendlela yokubuyisa idatha ngokwenza, ngokulanda okuzenzakalelayo noma ngedivayisi efana nenduku ye-USB. Ingabe udinga ikhono lokuhlela idatha noma ukuyithumela ngefomethi ukuze isetshenziswe nezinye izinhlelo ezifana ne-Microsoft Excel? Qiniseka ukuthi uyaqonda ukuthi uzoyihlaziya kanjani idatha ukuze uthole ulwazi olufunayo.
10. Kuthiwani Ngokulinganisa, Ukunakekela Nokulungisa?
Ingabe udinga ukuthi idivayisi ilinganiswe ukuze ihlangabezane nezimfuneko ezithile zokubika zangaphakathi noma zangaphandle? Uma kunjalo, hlobo luni lokulinganisa oludingekayo, I-NIST iyalandeleka, ISO or I-A2LA ugunyaziwe? Ngabe i-logger idinga kangaki ukulinganiswa noma ukuseviswa ngokulungiswa okuvamile njengokushintshwa kwebhethri? Ingabe umthengisi uyanikeza izinsizakalo zokulungisa uma umgawuli elimele ngephutha?
11. Yiliphi Izinga Lokusekela Noma Lokuqeqeshwa Olidingayo?
Ingabe unabo abasebenzi enhlanganweni yakho abangakwazi ukuphatha izintambo nokucushwa kwe-logger yedatha noma uzodinga usizo lwangaphandle? Uzodinga ukuqeqeshwa? Iliphi izinga lokusekelwa umthengisi alinikezayo futhi kumahhala noma bayakukhokhisa ngakho? Abanye abahlinzeki futhi banikela ngezinsizakalo ezingeziwe zenani elifana nokwenza ngokwezifiso, ukumisa, ukuqeqeshwa, ukuhlela, njll.
12. Ungalutholaphi Usizo Olwengeziwe?
Ukukhetha uhlelo olufanele lokuloga idatha kubalulekile ekuqoqweni nasekuhlaziyweni kwedatha ngempumelelo. Ngokuchitha isikhathi esengeziwe ngaphambili futhi ucabange ngokucophelela le mibuzo eyishumi eyisihluthulelo ukuze uchaze ngokugcwele izidingo zakho, unethuba elingcono kakhulu lokuphetha ngomkhiqizo owanelisa zonke izidingo zakho.
