Intshayelelo

Kwimveliso yamaphepha yanamhlanje,Izilawuli zeNgcaciso ezicwangcisekileyo (PLCs)sebenza njenge"ingqondo" yokuzenzekela, ukwenza ulawulo oluchanekileyo, ukuxilongwa kwempazamo, kunye nokulawulwa kwamandla. Eli nqaku liphonononga ukuba iinkqubo ze-PLC zonyusa njani ukusebenza kakuhle kwemveliso ngo15–30%ngelixa uqinisekisa umgangatho ongaguqukiyo.(Amagama angundoqo we-SEO: I-PLC kumzi-mveliso wephepha, umatshini we-automation wephepha, ukuveliswa kwephepha elihlakaniphile)

1. Usetyenziso oluphambili lwee-PLCs kuVeliso lwamaPhepha

1.1 Ulawulo loLungiselelo lwePulp

• Ulungelelwaniso lwesantya sepulper oluzenzekelayo(±0.5% ukuchaneka)
• Idosi yeekhemikhali elawulwa yi-PID(8–12% yokonga impahla)
• Ixesha langempela lokujonga ukuhambelana(0.1g/L ukuchaneka)

1.2 Ukwenziwa kwePhepha kunye nokuCofa

• Ulawulo lokususa amanzi kwindawo yocingo(<50ms impendulo)
• Ubunzima besiseko / umswakama ovaliweyo wolawulo lwelophu(I-CV <1.2%)
• Usasazo lomthwalo wezowuni ezininzi(ungqamaniso lwamanqaku ali-16)

1.3 Ukomisa kunye nokuBhala

• Umphunga cylinder iprofayile yobushushu(±1°C ukunyamezela)
• Ulawulo loxinzelelo(I-40% yokunciphisa ikhefu kwiwebhu)
• Ukutshintsha kwe-reel okuzenzekelayo(<2mm impazamo yokubeka indawo)
• 

2. Izinto eziluncedo kwezobuGcisa kwiiNkqubo ze-PLC

2.1 Ulwakhiwo oluLawula amaLayi amaninzi

[HMI SCADA] ←OPC→ [Master PLC] ←PROFIBUS→ [I-Remote I/O] ↓ [Ulawulo loMgangatho weQCS]

2.2 Uthelekiso lweNtsebenzo

2.3 Ubunakho bokuDityaniswa kweDatha

• Modbus/TCPkuqhagamshelo lwe-MES/ERP
• 5+ iminyakayogcino lwedatha yemveliso
• Iingxelo ze-OEE ezizenzekelayoyokulandelela ukusebenza

3. I-Case Study: Uphuculo lwe-PLC kwi-Packaging Paper Mill

• Hardware:Siemens S7-1500 PLC
• Iziphumo:✓I-18.7% yokonga amandla(¥1.2M/ngonyaka) ✓Ukwehla kwezinga lesiphako(3.2% → 0.8%) ✓I-65% yokutshintsha umsebenzi ngokukhawuleza(45min → 16min)

4. Imizila yekamva kwi-PLC Technology

1. Edge Computing-Ukuqhuba ukuhlolwa komgangatho osekwe kwi-AI ekuhlaleni (<5ms latency)
2. Amawele eDijithali-Ukugunyaziswa okubonakalayo kunciphisa amaxesha eprojekthi ngama-30%
3. ULondolozo lwe-5G kude-Ixesha lokwenyani uhlalutyo lokuxela kwangaphambili kwimpilo yezixhobo

Ukuqukumbela

Ii-PLCs ziqhubela ishishini lamaphepha ukuyaUkuvelisa "izibane-zicimile".. Izindululo eziphambili: ✓ YamkelaI-IEC 61131-3 iyahambelanaAmaqonga e-PLC ✓ Uloliwei-mechatronics-idibeneyoIingcali ze-PLC ✓ UgcinoI-20% yokugcina i-I / O umthamoulwandiso lwexesha elizayo

(Amagama angundoqo omsila omde: inkqubo ye-PLC yomatshini wephepha, i-DCS ye-pulp mills, izisombululo zokuvelisa iphepha ezizenzekelayo)

Iinketho zokwenza ngokwezifiso

Ukuntywila nzulu kwi:

• Ukhetho oluthile lwe-PLC lweBrand(Rockwell, Siemens, Mitsubishi)
• Ingqiqo yokulawula iinkqubo ezithile(umz., ukulawula ibhokisi yentloko)
• I-Cybersecurity yothungelwano lwamashishini

Ndazise indawo ogxile kuyo. Idatha yoshishino ibonisaI-89% yokwamkelwa kwee-PLCs, kodwa kuphelaAma-32% asebenzisa imisebenzi ephucukileyongempumelelo.
