Ku habboon Dongfeng Cummins dareenka cadaadiska saliidda 4921489

1. Waa maxay dareemaha cadaadiska?

Dareemka cadaadiska waa qalab kasta oo ogaanaya cadaadiska ay ku sameeyaan walax ama jidh. Qadarka cadaadiska aaladda waxaa lagu qiyaasi karaa saameynta ay ku leedahay dareemayaasha. Dareemayaashu waxay noqon karaan dhijitaal ama analoog, laakiin si kastaba ha ahaatee, waxay u diri karaan calaamada akhriska ee qiimaha cadaadiska gaarka ah meel fog.

Erayga "sensor" sidoo kale waa eray guud iyo mid guud ilaa xad, oo ay ku jiraan qalab aad u gaar ah, sida transducers iyo transmitters. Si kale haddii loo dhigo, in kasta oo dhammaan beddelayaasha cadaadiska ay yihiin dareemayaal, maahan dhammaan dareemayaasha cadaadisku waa kuwa wax beddela. Waxa kale oo aad u tixraaci kartaa qaybaha nidaamka cabbiraadda ee sida tooska ah u saameeya cadaadiska sida "sensors", halkii aad ka ahaan lahayd qaybaha madaxbannaan ee nidaamka u beddela macluumaadkan calaamadaha elektarooniga ah.

2. Sidee u shaqeeyaa dareemaha cadaadiska?

Sida aaladda elektiroonigga ah, dareemaha cadaadiska ayaa ogaan kara oo la socon kara cadaadiska nidaamka dareeraha isaga oo u beddelaya xoogga jireed ee aaladda calaamad koronto.

Dareemka cadaadiska adag waa qayb ka mid ah nidaam weyn, kaas oo aan akhrin kaliya heerka cadaadiska lagu dabaqay nidaamka, laakiin dhab ahaantii wuxuu mas'uul ka yahay kormeerka iyo xakamaynta nidaamka iyada oo laga jawaabayo heerka cadaadiska la ogaaday. Iyada oo isbeddelka cadaadiska, soo-saarka calaamadda dareenka ayaa sidoo kale isbeddeli doona. Tani waxay kicin kartaa kontaroolada loo habeeyey inay shid, damiso ama hagaajiso heerka qaybaha nidaamka ee meelaha la ogaaday.

3. Waa maxay cadaadiska cadaadiska?

Transducer cadaadiska waa nooc ka mid ah dareemayaasha cadaadiska, kaas oo ka kooban walxaha xasaasiga ah ee cadaadiska iyo walxaha beddelka calaamadaha. Transducer-ku wuxuu u beddelaa calaamad koronto oo hooseeya oo ka yimaada cadaadiska farsamada (gaaska ama dareeraha) oo u beddela koronto saamile ah ama soosaarka milliampere. "Transduction" macnaheedu waa "isbedel".

4. Waa maxay shaqada cadaadiska cadaadiska?

Transducer-ku wuxuu akhriyaa cadaadiska nidaamka dareeraha. Kadibna, korontada ama wax-soo-saarka transducer-ga hadda waxa loo gudbin karaa meel fog si loola socdo loogana wargeliyo xakamaynta tooska ah ama gacanta ee nidaamka. Noocyada wax soo saarka Analog waxaa ka mid ah: 4-20 mA, 0-5 VDC, 0-10 VDC, 1Vac ama 0.333Vac. Haddii aad isticmaashid gudbiyaha cadaadiska dhijitaalka ah ( gudbiyaha cadaadiska AKA), qalabka elegtarooniga ah ee horumarsan ayaa ku siin kara shaqada diritaanka calaamadaha iyada oo loo marayo borotokoolka isgaarsiinta warshadaha sida Modbus ama BACnet.

5. Qalalaasaha cadaadiska qoyan

Qalalaasaha cadaadiska qallalan wuxuu cabbiraa kala duwanaanshaha cadaadiska dhexdhexaadka engegan (sida nidaamka dhuumaha hawada ama gaaska), halka beddeliyaha cadaadiska qoyan uu oggolaanayo cadaadiska nidaamka qoyan (sida dhuumaha).
