Hauv kev tsim cov ntawv niaj hnub,Programmable Logic Controllers (PLCs)ua hauj lwm raws li cov"lub hlwb" ntawm automation, ua kom muaj kev tswj xyuas meej, kev kuaj xyuas tsis raug, thiab kev tswj xyuas lub zog. Tsab ntawv xov xwm no tshawb txog yuav ua li cas PLC systems txhim kho kev tsim khoom los ntawm15-30%thaum ua kom zoo ib yam.(SEO keywords: PLC hauv ntawv kev lag luam, ntawv tshuab automation, ntse ntawv manufacturing)

1. Cov ntawv thov tseem ceeb ntawm PLCs hauv Kev Tsim Ntawv

1.1 Pulp Preparation Control

• Tsis siv neeg pulper ceev hloov(± 0.5% qhov tseeb)
• PID-tswj tshuaj noj tshuaj(8-12% cov khoom txuag)
• Kev tshuaj xyuas qhov sib xws ntawm lub sijhawm(0.1g / L precision)

1.2 Daim Ntawv Tsim & Nias

• Hlau seem dewatering tswj(<50ms teb)
• Qhov hnyav / noo noo kaw-loop tswj(CV <1.2%)
• Multi-zone xovxwm load faib(16-point synchronization)

1.3 Qhuav & Winding

• Chav cylinder kub profileing(± 1 ° C kam rau ua)
• Kev tswj nruj(40% txo qis hauv web so)
• Tsis siv neeg reel hloov( <2mm qhov chaw yuam kev)
• 

2. Technical Advantages ntawm PLC Systems

2.1 Multi-Layer Control Architecture

[HMI SCADA] ← OPC → [Master PLC] ← PROFIBUS → [Chaw Taws Teeb I/O] ↓ [QCS Kev Tswj Xyuas Zoo]

2.2 Kev sib piv kev ua haujlwm

2.3 Muaj peev xwm sib sau ua ke cov ntaub ntawv

• Modbus/TCPrau MES / ERP txuas
• 5+ xyoontawm kev tsim cov ntaub ntawv khaws cia
• Automated OEE qhiarau kev taug qab kev ua haujlwm

3. Case Study: PLC hloov kho hauv ib lub tshuab ntim ntawv

• Kho vajtse:Siemens S7-1500 PLC
• Cov txiaj ntsig:✓18.7% kev txuag hluav taws xob(¥1.2M/xyoo) ✓Tus nqi poob qis(3.2% → 0.8%) ✓65% kev hloov pauv sai dua(45 feeb → 16 min)

4. Yav tom ntej Trends hauv PLC Technology

1. Edge Computing- Khiav AI-raws li kev soj ntsuam zoo hauv zos (<5ms latency)
2. Digital Twins- Virtual commissioning txiav cov sijhawm ncua sij hawm los ntawm 30%
3. 5G Chaw Taws Teeb Saib Xyuas- Real-time kev kwv yees tsom xam rau cov khoom siv kho mob
