Ukulawulwa kwezibani zamaleveli amaningi kuklanyelwe ukusebenzisa ukulawula okulula nokonga amandla kwezinhlelo zokukhanyisa; kusetshenziswa lapho kudingeka khona ukukhanyisa noma ukucisha izibani ezivela ezindaweni eziningana, ukukhanyisa noma ukucisha izibani ngamaqembu, noma ukushintshwa okujwayelekile okumaphakathi noma icishiwe.
Ake sicabangele izixazululo ezimbalwa eziyisisekelo kanye nemikhiqizo ngokombono wokubekezelela iphutha lehadiwe, futhi ngenxa yalokho ukusebenza kwangempela kwesikhathi eside.
Isibonelo sesistimu yokulawula izibani enamazinga amaningi
Ukulawulwa kwezinga 1 - yonke imithombo yokukhanyisa esakhiweni, kuhlanganise naleyo elawulwa ezindaweni eziningana.
Izinga le-2 lokulawula - imithombo yokukhanya ehlanganiswe eqenjini ephikweni lesobunxele lesitezi sokuqala, imithombo yokukhanya ehlanganiswe eqenjini elingakwesokudla kwesitezi sokuqala, imithombo yokukhanya ehlanganiswe yaba yiqembu ephikweni lesobunxele lesitezi sesibili, imithombo yokukhanya ehlanganiswe yaba yiqembu ophikweni olungakwesokudla lwesitezi sesibili.
Izinga lesi-3 lokulawula - imithombo yokukhanyisa ehlanganiswe yaba yiqembu esitezi sonke sokuqala, imithombo yokukhanyisa ehlanganiswe eqenjini esitezi sonke sesibili.
Izinga lesi-4 lokulawula - imithombo yokukhanyisa ehlangene ibe yiqembu endlini yonke.
Izixazululo okungakhelwa kuzo uhlelo olunjalo
1.PLC.
2. Ukudluliselwa kwe-Pulse.
3. Inkimbinkimbi ye-Hardware Non-Programmable Logic (CTS NPL) esekelwe kumadivayisi okulawula ukukhanya okuklama kwethu.
Ungafunda nge-CTS NPL esihlokweni .
Idivayisi yokulawula ukukhanya kwe-electromechanical iyimojula yokulawula ehlangene ukuze ifakwe kumzila wesitimela we-DIN ongu-36 mm ububanzi (amamojula angu-2).
Ukubusa
Ukulawula kwenziwa kusetshenziswa inkinobho ephindwe kabili enoxhumana nabo ababili abavame ukuvuleka.
Isizathu sokuthuthukisa i-CTS NPL
Isizathu sokuthuthukiswa kwe-KTS NPL kwakuwukucaciswa kobuchwepheshe kwekhasimende, elalifuna ukusebenzisa ukusebenza kohlelo lokulawula ukukhanyisa olunamazinga amaningi ngaphandle kokusebenzisa i-PLC (ngoba ukubhuka kubiza kakhulu).
Isibonelo sokusebenza kwesistimu yokulawula ukukhanyisa kwamazinga amaningi endlini encane
Ake sicabangele isistimu ebekezelela amaphutha esekelwe kumadivayisi okulawula ukukhanya
Izithako:
1. Imishini yokulawula ukukhanya.
Izindleko zezisetshenziswa: $47 ngomthombo owodwa wokukhanya.
Ukuqina kukagesi: 100 imijikelezo ye-AC-000.
Uma enye yemishini yokulawula ukukhanyisa ihluleka, wonke amanye amadivaysi esistimu yokulawula ukukhanyisa azoqhubeka nokusebenza.
Lokhu kusho ukuthi uma idivayisi yokulawula ukukhanyisa iphuka, ukukhanya kuzoqhubeka nokusebenza, ngaphandle komthombo owodwa wokukhanya, noma inkinobho yeqembu elilodwa, kuyilapho uchwepheshe efaka imishini emisha futhi eyisebenzisa.
Cabangela uhlelo olusekelwe ku-PLC olungabekezeleli amaphutha
Izithako:
1. Isilawuli esinengqondo esihlelekayo.
2. Gcina isilawuli se-logic esihlelekayo.
3. Amamojula we-I/O.
4. Amamojula e-I/O angasadingeki.
5. Idivayisi yokungasebenzi (ihlinzeka ngokulawula ukushintshela ku-PLC eyisipele kanye namamojula e-I/O ayisipele).
6. Ukudluliselwa okuphakathi.
7. Ama-Actuator (ama-relay/contactor).
Izindleko zezisetshenziswa: $237 ngomthombo owodwa wokukhanya.
Ukuqina kukagesi: 100 imijikelezo ye-AC-000.
Uma amamojula e-PLC noma e-I/O ehluleka, idivayisi eyisipele izoshintsha ukulawula ngesikhathi sangempela iye ku-PLC eyisipele namamojula e-I/O ekhophi yasenqolobaneni futhi ibonise ukwehluleka.
Lokhu kusho ukuthi uma i-PLC iphuka, ukukhanya kuzoqhubeka nokusebenza ngenkathi uchwepheshe efaka imishini emisha futhi eyisebenzisa.
Cabangela uhlelo lwe-PLC olungasadingeki
Izithako:
1. Isilawuli esinengqondo esihlelekayo.
2. Amamojula we-I/O.
3. Ukudluliselwa okuphakathi.
4. Ama-Actuator (ama-relay/contactor).
Izindleko zezisetshenziswa: $69 ngomthombo owodwa wokukhanya.
Ukuqina kukagesi: 100 imijikelezo ye-AC-000.
Uma amamojula e-PLC noma e-I/O ehluleka, ukukhanyisa kuzoyeka ngokuphelele ukusebenza kuze kube yilapho uchwepheshe efaka futhi ekhipha imishini emisha.
Ake sicabangele uhlelo oluvame kakhulu olususelwa ku-PLC emkhakheni wezindawo zokuhlala
Izithako:
1. Isilawuli esinengqondo esihlelekayo
2. Amamojula we-I/O
3. Ukudluliselwa okumaphakathi kokufakiwe
Izindleko zezisetshenziswa: $41 ngomthombo owodwa wokukhanya.
Ukuqina kukagesi: 25 imijikelezo ye-AC-000.
Uma i-PLC noma amamojula okufaka / okukhiphayo ehluleka (lokhu kuzokwenzeka ngokushesha kakhulu kunezinguqulo zangaphambilini, njengoba ukumelana nokugqoka kukagesi kuphansi izikhathi ezine), ukukhanya kuzoyeka ngokuphelele ukusebenza kuze kube yilapho uchwepheshe efaka futhi ehambisa imishini emisha.
Ake sicabangele uhlelo olususelwe kuma-pulse relay
Izithako:
1. Ukudluliselwa kwe-Pulse.
2. Amamojula okulawula iqembu.
3. Amamojula okulawula aphakathi.
Izindleko zezisetshenziswa: $73 ngomthombo owodwa wokukhanya.
Ukuqina kukagesi: 100 imijikelezo ye-AC-000.
Uma i-relay eyodwa ihluleka, zonke ezinye izidluliseli ohlelweni lokulawula ukukhanyisa zizoqhubeka nokusebenza.
Lokhu kusho ukuthi uma i-pulse relay iphuka, ukukhanya kuzoqhubeka nokusebenza, ngaphandle komthombo owodwa wokukhanya, noma inkinobho yeqembu elilodwa, kuyilapho uchwepheshe efaka imishini emisha futhi eyisebenzisa.
Uma uthi nhlΓ‘, ukudluliselwa kwe-pulse akufani kakhulu namadivayisi okulawula ukukhanya, kodwa akunjalo; ukudluliselwa kwe-pulse kunenani lemikhawulo:
1. Umkhawulo wenani lokushintsha: 5-15 ukushintsha ngomzuzu / 100 ukushintsha ngosuku.
2. Umkhawulo wobude be-Pulse: 50 ms - 1 s.
3. Ukudlidliza kungaholela ekushintsheni okuzenzakalelayo, okungukuthi, uma kunesidingo, ngeke kusakwazi ukufaka othintana nabo kukhabhinethi yokulawula enjalo.
4. Uma ngesikhathi esisodwa uvula/uvala ama-impulse relays aseduze, kungadingeka ukungena komoya kanye nokupholisa ikhabhinethi yokulawula.
5. Njengoba inani lamazinga okulawula likhula, ubunzima bokwakha isifunda buyanda.
isiphetho
Isistimu yokulawula ukukhanyisa kwamazinga amaningi ebekezelela amaphutha esekelwe ku-PLC inezindleko eziphakeme kakhulu zomkhakha wokuhlala, isistimu esekelwe ekusakazweni kwe-pulse inemikhawulo engathi sΓna, uhlelo olusekelwe kumadivayisi okulawula izibani luyincazelo yegolide.
