Phapano ke efe lipakeng tsa HMI le PLC?
Tafole ea likateng
- 1. HMI segokanyimmediamentsi sa sebolokigolo motho:
- 2. Menahano e hlophisehileng ea PLC:
- 3. Menahano e hlophisehileng ea PLC e ka sebelisoa bakeng sa boiketsetso ba indasteri:
- 4. HMI ea motho-mochini e ka sebelisoa likoloing:
- 5. Phapano ke efe lipakeng tsa HMI le PLC:
1. HMI segokanyimmediamentsi sa sebolokigolo motho:
HMI e boetse e bitsoa sebopeho sa mochini oa motho, se tsejoang hape e le "interface ea mochini oa motho". Sehokelo sa mochini oa batho ke mokhoa oa puisano le phapanyetsano ea tlhahisoleseling lipakeng tsa sistimi le mosebelisi. Mosebelisi a ka sebelisana kapa a laola sesebelisoa. Mofuta oa tšebelisano o kenyelletsa empa ha o felle feela ho phanele ea taolo ea ts'ebetso, e kenyelletsang sebopeho sa software, mochini oa maikutlo, jj.
Theknoloji ea HMI e ntse e hola le ho feta. Ho tloha ho li-buttons tsa setso ho ea ho li-skrini tsa morao-rao le theknoloji ea sebele, HMI ea morao-rao e atisa ho sebelisoa lits'ebetsong tsa taolo ea indasteri, matlo a bohlale, taolo ea ka hare ea likoloi, lisebelisoa tsa bongaka le masimo a mang.
2. Menahano e hlophisehileng ea PLC:
Merero e hlophisehileng ea PLC e sebelisoa ka ho khetheha lits'ebetsong tsa taolo ea indasteri tse nang le likhomphutha tsa indasteri tsa 4U. Ka kakaretso e sebelisoa liindastering tse bohlale tsa tlhahiso, melapo ea tlhahiso ea liindasteri, taolo ea ts'ebetso, joalo-joalo. Monahano oa eona o ka sehloohong ke ho sebelisa tlhahiso ea matšoao le taolo ea tlhahiso ho latela logic e behiloeng esale pele.
3. Menahano e hlophisehileng ea PLC e ka sebelisoa bakeng sa boiketsetso ba indasteri:
Taba ea bobeli, PLC e ka sebelisoa hape bakeng sa taolo ea motsamao, joalo ka phallo ea likarolo tsa sesebelisoa sa mochini, tseo hangata li hlahisoang ka bongata ba dijithale. Tsela e atlehang ka ho fetisisa ea ho laola motsamao ke ho sebelisa NC, e leng theknoloji ea taolo ea dijithale. Theknoloji ena e thehiloe thekenoloji ea taolo ea lik'homphieutha ea Amerika 'me hona joale e phethahetse haholo.
4. HMI ea motho-mochini e ka sebelisoa likoloing:
Human-Machine Interface (HMI) likoloing e bapala karolo ea bohlokoa ho netefatsa hore mokhanni o lula a tseba a bile a laola koloi.
Boikutlo ba Taolo: HMI e fana ka tlhaiso-leseling ea nako ea nnete mabapi le boemo ba koloi, joalo ka lebelo, lebelo la mafura, khatello ea mabili le lintlha tse ling tsa bohlokoa. Sena se etsa bonnete ba hore mokhanni o tseba boemo ba koloi mme a ka etsa liqeto a e-na le tsebo, e leng ho fokotsang kotsi ea likotsi ka lebaka la ho hloka temoho.
Maikutlo a Mechanism: Sistimi ea HMI e fana ka maikutlo ka mokhoa oa tlhokomeliso, mabone a lemosang, litsebiso tsa molumo, kapa maikutlo a pono. Ka mohlala, haeba koloi e feta tekanyo ea lebelo, tsamaiso ea HMI e ka lemosa mokhanni, e fokotsa kotsi ea likotsi tse amanang le lebelo.
Thibelo ea Likotsi: Sistimi ea HMI e ka kopanngoa le li-sensor, lik'hamera, le mahlale a mang a tsoetseng pele likoloing tsa sejoale-joale ho lekola maemo a ho khanna ka nako ea nnete. Lisebelisoa tsena li ka fa mokhanni litemoso mabapi le likotsi tse ka hlahang, tse kang likoloi tse haufi, batho ba tsamaeang ka maoto, kapa litšitiso, ho thusa ho thibela likotsi pele li etsahala.
5. Phapano ke efe lipakeng tsa HMI le PLC:
Le hoja ka bobeli HMI (Human-Machine Interface) le PLC (Programmable Logic Controller) e le likarolo tsa bohlokoa ho liindasteri tse ikemetseng, li sebeletsa mesebetsi e fapaneng:
HMI (Sebopeho sa Motho-Mochini): HMI ke sehokelo seo ka sona batho ba sebelisanang le mechini kapa litsamaiso tsa taolo. E bonts'a lintlha le li-status ho tsoa ho sistimi ka mokhoa o bonolo oa basebelisi, o lumellang basebelisi ho beha leihlo le ho laola lits'ebetso. Hangata li-HMI li kenyelletsa li-touchscreens le li-interface tsa graphical tse fanang ka lintlafatso tsa nako ea nnete le maikutlo. Sepheo sa HMI ke ho sebelisana ha basebelisi, boemo ba sistimi, le boiketlo ba ts'ebetso. Indasteri Panel PC e fana ka tharollo e ntle ea ho theha litsamaiso tsa HMI.
PLC (Selaoli se ka Lebelloang sa Maikutlo): Li-PLC ke likhomphutha tse ikhethileng tse sebelisoang ho laola le ho iketsetsa lits'ebetso tsa indasteri. Ba sebelisa logic e reriloeng esale pele ho beha leihlo lintho tse kentsoeng (joalo ka lisensara) le ho laola lintho tse hlahisoang (joalo ka li-motor, mabone kapa li-valve). Li-PLC li sebetsana le taolo ea 'nete ea mechini le lits'ebetso, li etsa mesebetsi e ipapisitseng le logic le litaelo tse hlophisitsoeng. Li etselitsoe ho tiea le ho ts'epahala libakeng tse thata tsa indasteri.
Kakaretso:
- HMI ke sehokelo bakeng sa basebelisi ba batho ho beha leihlo le ho sebelisana le sistimi. IP65 Touch Panel PC e ka ba e loketseng bakeng sa tikoloho ea indasteri ea kantle.
- PLC ke molaoli ea sebetsanang le lintho tse kenang le ho phethahatsa litaelo tsa ho laola mechine le litsamaiso tsa indasteri.
Ka mokhoa o tloaelehileng oa ho seta, PLC e phethahatsa logic ea taolo, ha HMI e lumella basebetsi ho bona boemo le ho etsa liphetoho kamoo ho hlokahalang. Bakeng sa litharollo tse tsoetseng pele tsa HMI, o ka sheba mefuta e fapaneng ea li-PC tsa phanele ea indasteri, joalo ka 8-inch Industrial Panel PC, 10-inch Industrial Panel PC, 12-inch Industrial Panel PC, kapa 15-inch Industrial Panel PC. Bakeng sa lipontšo tse kholoanyane, likhetho tse kang tsa 17-inch Industrial Panel PC le 19-inch Industrial Panel PC e ka ba e loketseng. Haeba o hloka skrine e kholoanyane, nahana ka eona 21-inch Industrial Panel PC.
Sena se tla ntlafatsa sistimi ea hau ea HMI ka litharollo tse matla le tse ka senyehang tse etselitsoeng litlhoko tse ikhethang tsa indasteri.
