Sidee Loo Doortaa Fiilada Qalabka Badan ee Saxda ah ee Mashruucaaga?
- Jawaabta Tooska ah: Qaab-dhismeedka Xulashada Afar-tallaabo ah
Dadku had iyo jeer way weydiiyaan:"Sideen u dooran karaa fiilada qalabka badan ee saxda ah ee mashruucayga?"
Jawaabta fudud:Waxaad u baahan tahay inaad sameyso afar go'aan oo aasaasi ah si isku xigxig ah:
| Tallaabo | Go'aan | Halbeegyada Muhiimka ah |
| Tallaabada 1aad | Tirada lammaanayaasha | Immisa calaamadood? (1 ilaa 100+ lammaane) - qorshe loogu talagalay qaybaha dheeraadka ah (15-20%) |
| Tallaabada 2aad | Cabbirka hagaha | 18-24 AWG (0.5-2.5mm²) - waxay ku xiran tahay dhererka wareegga iyo hadda |
| Tallaabada 3aad | Nooca gaashaanka | Foorno (100%), tidcan (70-95%), ama isku-dhafan - oo ku salaysan jawiga EMI |
| Tallaabada 4aad | Waxyaabaha jaakadda | PVC (guud), LSZH (badbaadada dabka), PUR (saliid/xabag) - oo ku salaysan deegaanka |
Maxaa loo sameeyaa Multi-Labo?Marka aad haysato qalab badan (cadaadis, heerkul, socod) oo ka socda isla sanduuqa isku xirka una socda qolka koontaroolka, fiilo badan oo laba-labo ah ayaa ka dhaqaale badan oo habaysan marka loo eego socodsiinta fiilooyinka shaqsiga ah. Hal fiilo badan oo laba-labo ah (tusaale ahaan, 20 lammaane) ayaa beddelaya 20 fiilo oo shaqsi ah - meel yar oo saxaarad ah, rakibid dhakhso leh, iyo joojin yar.
Dingzun Cable,Waxaan soo saarnaa fiilooyin qalab oo badan oo ka kooban 1 ilaa 100+ lammaane, si buuxda ayaa loo habeyn karaa iyadoo loo eegayo shuruudaha mashruucaaga - iyadoo la raacayo u hoggaansanaanta EN 50288-7 iyo dukumentiyada tijaabada oo dhammaystiran.
- Tallaabada 1aad: Go'aami Tirada Lamaanaha Saxda ah
Tirada lammaanaha waa go'aanka ugu aasaasiga ah. Hoos u dhig oo waxaad la'dahay awood aad mustaqbalka ugu ballaarin karto; xad-dhaaf u sheeg oo waxaad lacag ku lumisaa lammaane aan la isticmaalin.
Shaxda 1: Fiilada Lammaanaha Badan - Tilmaamaha Xulashada Tirinta Lamaanaha
| Tirada Lammaanaha | Codsiyada Caadiga ah | Talo soo jeedinta Lamaanaha Dheeraadka ah |
| 1-2 lammaane | Qalab keliya, oo hal dhibic-ilaa-bar (tusaale, hal gudbiye cadaadis) | 0-1 oo dheeri ah |
| 4-8 lammaane | Sanduuqa isgoyska yar, guddi maxalli ah (tusaale ahaan, 4-8 qalab) | 15-20% (tusaale ahaan, 8-labo oo loogu talagalay 6 qalab) |
| 10-20 lammaane | Guddi isku-dubarid dhexdhexaad ah, simbiriirixan qalab (tusaale ahaan, 10-20 calaamadood) | 15-20% (tusaale ahaan, 20-labo oo loogu talagalay 16 qalab) |
| 24-50 lammaane | Sanduuqa isgoyska weyn, qolka isku xirka DCS | 15-20% (tusaale ahaan, 50-labo oo loogu talagalay 40 qalab) |
| 50-100+ lammaane | Laf-dhabarta qolka kontoroolka ugu weyn, nidaamka DCS ee weyn | 10-15% (kharashka iyo is-weydaarsiga ballaarinta) |
Sida Loo Xisaabiyo Lammaanayaasha Loo Baahan Yahay:
| Tallaabo | Xisaabinta | Tusaale |
| 1 | Tiri qalabka firfircoon (calaamadaha) | 24 qalab |
| 2 | Ku dar qaybaha dheeraadka ah (15-20% ayaa lagu talinayaa) | 24 × 1.15 = 27.6 ≈ 28 |
| 3 | Hubi noocyada calaamadaha kala duwan (analog iyo digital - way wadaagi karaan lammaane haddii si habboon loo ilaaliyo) | Fiilada isku midka ah badanaa waa la aqbali karaa |
| 4 | Ku soo koob tirada lammaanayaasha caadiga ah | 30 lammaane(ama 32 lammaane iyadoo ku xiran soo saaraha) |
Caddayn Lamaane Dheeraad ah:
| Sababta | Kharashka Haynta Qalabka Kaydka ah |
| Ballaarinta mustaqbalka (qalab cusub) | Jiid cusub oo fiilada ah - shaqada, booska saxaaradda, waqtiga nasashada |
| Lamaanihii fashilmay (waxyeello ayaa soo gaartay intii lagu jiray rakibidda) | Beddelka fiilada oo dhan ama socodsiin gooni ah |
| Kala soocidda calaamadaha (buuqa ka imanaya hal lammaane oo saameeya mid kale) | Lama go'doomin karo iyada oo aan la helin kayd dheeraad ah |
(Fiilada qalabka ee iskutallaabta badan)
Dingzun Cable,Waxaan soo saarnaa fiilooyin badan oo isku xiran oo leh tirooyin caadi ah (2, 4, 6, 8, 10, 12, 16, 20, 24, 30, 36, 48, 50, 60, 100 lammaane) iyo tiro kasta oo gaar ah oo aad qeexdo.
- Tallaabada 2: Xullo Cabbirka Kontoroolka Saxda ah (AWG / mm²)
Cabbirka hagaha ayaa go'aamiya iska caabbinta wareegga, kaas oo si toos ah u saameeya inta aad ku socodsiin karto wareegga 4-20mA ama isgaarsiinta dijitaalka ah.
Shaxda 2: Xulashada Cabbirka Konduriyaha - 18 ilaa 24 AWG (0.5 ilaa 2.5 mm²)
| Cabbirka Hardcore-ka | AWG | Iska caabbinta (Ω/km) | Masaafada Wareega 4-20mA ee Caadiga ah (24V, 250Ω culays) | Codsiga ugu Fiican |
| 0.5 mm² | 20 AWG | ~33 Ω/km | 500-800 mitir | Gaaban ilaa dhexdhexaad ah, kharash-xasaasi ah |
| 0.75 mm² | 18-19 AWG | ~24 Ω/km | 800-1,200 mitir | Heerka ugu sarreeya ee qalabka warshadaha badankood |
| 1.0 mm² | 17-18 AWG | ~18 Ω/km | 1,200-1,500 mitir | Socod dheer, wareegyo iska caabin sare leh |
| 1.5 mm² | 16 AWG | ~13 Ω/km | 1,500-2,000+ mitir | Aalado aad u dheer, oo awood u leh inay shaqeeyaan |
| 2.5 mm² | 14 AWG | ~8 Ω/km | >2,500 mitir | Codsiyada gaarka ah (masaafo aad u dheer) |
Sida Loo Xisaabiyo Dhererka Wareegga Ugu Badan (4-20mA):
Wareegga 4-20mA waxaa xaddidaya iska caabbinta wareegga guud = iska caabbinta fiilada (labada dhinacba) + iska caabbinta culayska (250Ω caadiga ah) + iska caabbinta caqabadda (haddii la isticmaalo).
| Halbeegga | Qaaciddada | Tusaale |
| Iska caabbinta wareegga ugu badan (24V oo sahay ah) | (Vsupply – Vmin_device) / 0.02A | (24V – 12V) / 0.02A = 600Ω |
| Ka jar culayska iyo caqabadda | 600Ω – 250Ω (rar) – 50Ω (caqabad) = 300Ω | Waxaa laga heli karaa fiilada |
| Iska caabbinta fiilada (safar wareeg ah) | 2 × R_km × Masaafada (km) | 2 × 24Ω/km × 1.2km = 57.6Ω |
| Masaafada ugu badan ee 0.75mm² (18 AWG) | Iska caabbinta fiilada ee la heli karo / (2 × R_km) | 300Ω / (2 × 24Ω/km) =6.25 km? Aad ayuu u sarreeyaa - hubi qalabka |
*(Fiiro gaar ah: Masaafada wax ku oolka ah ee 4-20mA waxaa xaddidaya awoodda qalabka iyo awoodda, badanaa 800-1,500m ugu badnaan 18 AWG)*
Signalada Dijitaalka ah (RS485, Modbus):
| Cabbirka Hardcore-ka | Masaafada ugu badan (9.6 kbps) | Qodobka Xaddidaadda |
| 24 AWG (0.2mm²) | 1,200 mitir (heerka ugu badan ee RS485) | Awoodda iyo hoos u dhaca |
| 22 AWG (0.34mm²) | 1,200 mitir | Isku mid ah - masaafada aan iska caabintu ku xaddidnayn baud hooseeya |
| 18-20 AWG | 1,200 mitir | Qafiif uma baahna koronto; u isticmaal xoogga farsamada |
Talo soo jeedin:Qalabka warshadaha badankood (4-20mA, RS485, RTD, thermocouple),0.75mm² – 1.0mm² (18 AWG)waa doorashada caadiga ah - dheelitirka kharashka, awoodda masaafada, iyo xoogga farsamada. Isticmaal cabbirro waaweyn si aad u hesho wareegyo aad u dheer ama meesha xoogga jiidista farsamada ay tahay arrin walaac leh.
Dingzun Cable,Waxaan bixinaa fiilooyin badan oo labo-labo ah oo leh 18 AWG (0.75mm²) oo caadi ah, oo leh 16 AWG (1.5mm²), 20 AWG (0.5mm²), iyo cabbirro gaar ah oo la heli karo iyadoo loo eegayo xisaabinta dhererka wareeggaaga.
- Tallaabada 3: Dooro Nooca Difaaca Saxda ah
Gaashaanku wuxuu ka ilaaliyaa calaamadahaaga EMI (matoorada, VFD-yada, raadiyaha, alxanka). Doorashadu waxay ku xiran tahay deegaankaaga korontada.
Shaxda 3: Noocyada gaashaanka ee fiilooyinka qalabka badan-labo-labo
| Nooca Gaashaanka | Daboolida | Soo noqnoqoshada ugu Fiican | Waxtarka Difaaca (SE) | Codsiga ugu Fiican | Kharashka Qaraarka |
| Foorno (Qofkiiba lammaane) | 100% | Sare (>1 MHz) | 60-90 dB (RFI) | Calaamadaha analogga ee muhiimka ah- waxay ka hortagtaa iskutallaabta u dhaxaysa lammaanayaasha isku fiilo isku mid ah | 1.0 × (saldhigga) |
| Faylka Guud(dhammaan lammaanayaasha) | 100% | Sare (>1 MHz) | 60-90 dB (RFI) | Rakibaadda go'an, EMI dhexdhexaad ah, kharash-xasaasi ah | 1.1 × |
| Timo guud | 70-95% | Dhexdhexaad Hoose ( | 40-80 dB | Firfircoon/jilicsan- fiilada korontada, robotics-ka, cadaadiska farsamada sare | 1.3-1.5 × |
| Isku-dhafan (Fayil + Tidcan) | 100% + timo tidcan | Muuqaal Buuxa | >90 dB | Warshadeed adag- VFDs, matoorro, warshado koronto, warshado sifeyn | 1.5-2.0 × |
Tixgelinta Gaarka ah ee Lammaane Badan - Isku-xidhka:
Marka lammaane badan ay wadaagaan fiilo isku mid ah, calaamadaha ka imanaya hal lammaane ayaa si awood leh isugu xidhi kara lammaane isku xiga (isweydaarsiga hadalka).
| Codsiga | Qaabeynta Gaashaandhigga ee lagu taliyay |
| Isku-dhafka analogga (4-20mA) iyo dhijitaalka ah (RS485) oo ku jira isla fiilo isku mid ah | Foorno shaqsi ah lammaane kasta + tidcan guud- go'doomin iskutallaabta ah |
| Dhammaan calaamadaha isku nooc ayay yihiin (tusaale ahaan, dhammaan 4-20mA) | Faylka guud ama tidcan ayaa ku filnaan kara |
| Calaamadaha aadka u xasaasiga ah (thermocouple, mV) | Foorno shaqsi ah lammaane kasta + tidcan guud |
| Deegaanka EMI-ga Sare (VFDs, alxanleyaal) | Guud ahaan isku dhafan (foolada + tidcan)+ bir bir ah oo shaqsi ah lammaane kasta |
Dingzun Cable,Dhismaha fiilada qalabka ee caadiga ah ee isku-dhafan waa:bir bir ah oo ku jirta laba qof (100%) + bir bir ah oo guud ahaan qasacadaysan (≥85%)- bixinta labadaba ka hortagga isku-xidhka hadalka iyo ilaalinta EMI ee dibadda. Kani waa qaab-dhismeedka ugu habboon ee warshadaha.
- Tallaabada 4: Dooro Agabka Jaakadda Ku Salaysan Deegaanka
