Sengoloa sena se hlahloba kamoo litsamaiso tsa PLC li ntlafatsang katleho ea tlhahiso ka15–30%ha ka nako e ts'oanang ho netefatsa boleng bo tsitsitseng.(Mantsoe a bohlokoa a SEO: PLC indastering ea pampiri, othomathike ea mochini oa pampiri, tlhahiso ea pampiri e bohlale)

1. Litšebeliso tsa Bohlokoa tsa Li-PLC Tlhahisong ea Pampiri

1.1 Taolo ea Tokisetso ea Makhasi

• Phetoho ea lebelo la pulper ka boiketsetso(± ho nepahala ha 0.5%)
• Tekanyo ea lik'hemik'hale e laoloang ke PID(poloko ea thepa ea 8–12%)
• Tlhokomelo ea botsitso ea nako ea sebele(Ho nepahala ha 0.1g/L)

1.2 Ho Hlahisa le ho Tobetsa Maqephe

• Taolo ea ho tlosa metsi karolong ea terata(Karabelo ea <50ms)
• Taolo ea boima ba motheo/mongobo e koetsoeng(CV <1.2%)
• Kabo ea mojaro oa khatiso oa libaka tse ngata(Kamano ea lintlha tse 16)

1.3 Ho omisa le ho kobeha

• Tlhahlobo ea mocheso oa silindara ea mouoane(mamello ea ±1°C)
• Taolo ea tsitsipano(Phokotso ea 40% ho likheo tsa webo)
• Phetoho ea reel e iketsang(Phoso ea ho beha <2mm)

2. Melemo ea Tekheniki ea Mekhoa ea PLC

2.1 Moralo oa Taolo ea Mekhahlelo e Mengata

2.2 Papiso ea Tshebetso

2.3 Bokgoni ba ho Kopanya Dintlha

• Modbus/TCPbakeng sa khokahano ea MES/ERP
• Lilemo tse 5+polokelo ea data ea tlhahiso
• Litlaleho tsa OEE tse iketsangbakeng sa ho latela ts'ebetso

3. Thuto ea Nyeoe: Ntlafatso ea PLC ka har'a Mill ea Pakete ea Lipampiri

• Lisebelisoa:Siemens S7-1500 PLC
• Liphetho:✓Poloko ea matla ea 18.7%(¥1.2M/selemo) ✓Ho theoha ha sekgahla sa diphoso hantle(3.2% → 0.8%) ✓Liphetoho tsa mesebetsi tse potlakileng ka 65%(Metsotso e 45 → metsotso e 16)

4. Mekhoa ea Nakong e Tlang ho Theknoloji ea PLC

1. Khomphutha ea Edge– Ho tsamaisa tlhahlobo ea boleng e thehiloeng ho AI sebakeng sa heno (<5ms lateness)
2. Mafahla a Dijithale– Ho kenya tshebetsong lenaneo la inthanete ho fokotsa nako ya projeke ka 30%
3. Tlhokomelo ea 5G Remote- Litlhahlobo tsa ho bolela esale pele tsa nako ea sebele bakeng sa bophelo bo botle ba lisebelisoa
