Zaj ua ntej
Nyob zoo txhua tus! Hnub no Kuv yuav qhia nrog koj txiav -} uge {ntug thev naus laus zis uas ua kom muaj kev ruaj ntseg ntawm kev siv lub tshuab ua tshuab-Plc dual - network rov ua haujlwm. Tsis txhob txhawj, Kuv yuav siv cov kev ua piv txwv yooj yim thiab - ntiaj teb cov piv txwv los piav qhia txog cov lus qhia txuj ci no.Ntseeg kuv, Siv cov tshuaj no yuav txhawb koj txoj kab kev sib txuas lus ntau ntxiv kev sib txuas lus rau 99.99%! Xav paub seb nws ua tiav li cas?Ua raws li kuv piav!
Dab tsi yog network rov qab?
Xav txog koj lub Hoobkas kev sib txuas lus network zoo li lub nroog txoj kev system:
Ib Network: Tsuas muaj ib txoj kev loj. Thaum lub tsheb sib tsoo (network tsis ua hauj lwm) tshwm sim, tag nrho cov tsheb sib kis (cov ntaub ntawv kis) yuav yog tuag tes tuag taw.
Dual Network Rov Ua Dua: Muaj ob lub system, ib qho rau cov choj siab thiab lwm qhov rau hauv av.Txawm hais tias ib txoj kev thaiv, tsheb tuaj yeem hloov mus rau lwm txoj kev.
Hauv Plc System, Network redundancent ntseeg tau ib lub cim thaub qab sib kis tas los ntawm ob txoj kev sib txuas lus ywj pheej thiab cov khoom siv ywj siab. Yog tias lub network tseem ceeb, lub kaw lus cia li hloov mus rau Backup Network tsis pub dhau milliseconds, tawm hauv cov txheej txheem ntau kiag li tsis muaj kev cuam tshuam.
Vim li cas siv dua ob lub network rov qab?
Tej zaum koj yuav xav tsis thoob: "Tuaj peb lub hoobkas tau siv ib lub network rau ntau xyoo thiab nws tau zoo nkauj ruaj khov?" Cia peb saib cov noCov Lus Qhia Txog Cov Lus Qhia:
Lub tsheb vuam rhiav: Txoj hlua hloov ua tsis tau ua rau tag nrho cov kab kom nres rau 45 feeb, ua rau muaj kev ploj ncaj ntawm 800,000 Yuan.
Khoom Noj Ua Noj Kab: Network pob ntawv poob los ua cov ntawv qhia kev sib kis tsis zoo, ua rau cov scrapping ntawm tag nrho cov khoom lag luam
Tshuaj Nroj Tsuag Dcs System: Kev cuam tshuam kev sib txuas lus cuam tshuam ua rau kev ruaj ntseg cuam tshuam kev ruaj ntseg, yuav luag ua rau kev sib tsoo
Dual network rov qab tuaj yeem coj peb lub ntsiab tseem ceeb:
✅ 99.99% Kev Sib Txuas Lus Muaj: Lub sijhawm downtime txo los ntawm cov sij hawm mus rau feeb
✅SAMLESSTxav Mus: Cov sijhawm hloov tau yog<100ms, much faster than manual response
Tshaj TawmTxij Nkawm Qhov Rooj: Ib qho network tuaj yeem kho tsis tau yam tsis kaw lub kaw lus
4 Cov kev daws teeb meem rau dual network rov ua haujlwm
1. Ntiv nplhaib rov ua dua (MRP)
Zoo li subway lub voj voos kab, txhua cov khoom siv tau sau lub voj kaw, thiab kev sib txuas ntawm txhua qhov taw tes yuav tsis cuam tshuam kev sib txuas lus.
Qhov Zoo:
Tus nqi qis (tsuas yog siv tau zoo ib yam)
Siemens profinet thiab ab ethernet / IP yog ob leeg ib txwm txhawb nqa
2. Parallel Dual Tes Haujlwm (HSR / PRP)
Ob qho kev sib koom tes ywj pheej, Cov ntaub ntawv pob ntawv xa mus ib txhij, thiab qhov tau txais kawg cia li xaiv tus uas tuaj txog ua ntej.
Cov Kev Siv Raug Raug:
Cov Khoom Siv Hluav Taws Xob Tiv Thaiv Cov Khoom Siv (Txhaum Cov Ntaub Ntawv Sau Tseg, Ntau Yam Tiv Thaiv)
Hloov lub sijhawm=0 ms (vim tias tsis muaj kev hloov pauv yuav tsum tau)
3. Ntaus - qib rov ua dua
Cov khoom siv tseem ceeb (xws li PLC thiab HMI) yog nruab nrogDual network phaib, uas tau siv los ntawm kev tswj hwm pawg:
# Pseudocode: Dual Network Card plawv kev kuaj pom
Thaum muaj tseeb:
Yog tias ping (main_network) ==} tsis muaj tseeb:
Qhib (thaub qab_network)
Xa_alarm ("Lub network tseem ua hauj lwm, thaub qab hloov")
4. Tswv Yim Sib Tw Rov Qab
Mob siab rau cov cai xws liSiemens 'S7-RedconnectthiabRockwell's DLR siv cov hauv qab no ntawm txheej sib txuas lus:
Tsis Siv Neeg Kev Ua Haujlwm
Millisecond -} tus qib kev txhaum kev paub
Txhawb kub - swap hloov ntawm cov khoom siv
Cov Ntaub Ntawv Tiag: Kev hloov ntawm cov chaw muaj tswv yim hauv lub log tsheb
Qhov nyob nram qab: AGV Dispatching System ntawm txawv teb chaws -} Cov log tsheb muaj kev paub txog 2-3 cov khoom siv network, ua rau tuag tes tuag taw.
Kev Npaj Dua:
Lub cev txheej: Tso ob qho chaw ywj pheej hloov chaw (nquag: Hirschmann, thaub qab: Mosa)
Lub ntsiab: Star + nplhaib Hybrid Redundancy (Dual Kab ntawm txoj kev tseem ceeb, ib lub nplhaib hauv cov chaw sib txawv)
Kev teeb tsa kev teeb tsa kev teeb tsa: Pab tau cov profinet mrp raws tu qauv thiab teeb tsa 300ms kuaj kev voj voog
Qho kawg:
Xoom Txuas Txuas Lus Tsis Txaus rau 18 Lub Hlis Sib law
Ingning Lub sijhawm network hloov pauv tsuas yog 82ms (AGV yog kiag li insensitive)
Cov nyiaj tu txhua xyoo los ntawm kev poob qis tshaj 2 lab yuan
Tsib qhov loj loj cov lus ceeb toom hauv kev siv
Hloov cov teeb meem hloov pauv: MRP Raws Cai Ua raws kev siv tej zaum yuav txawv ntawm cov sib txawv
Network cua daj cua dub: Cov kev teeb tsa tsis txaus siab tshaj tawm yuav ua rau muaj kev tshaj tawm
IP Chaw Npaj: Dual Network Card Devices Yuav tsum tau muab faib cov ntu network (nws raug nquahu kom cov tes hauj lwm tseem ceeb thiab thaub qab thawj zaug)
Kev cuam tshuam hauv av: Kev ua si tsis zoo ntawm ob lub network tuaj yeem ua rau muaj kev sib txawv (cov nroj tsuag steel paub poob ntawm nws cov backup network vim yog av).
Software cov nqi laub: Qee cov yam ntxwv rov ua dua tshiab (xws li Siemens S7-1500 Software Redundancy pob).
