Kuunikira kwamitundu ingapo kudapangidwa kuti kukhazikitse njira zosavuta komanso zowongolerera zowunikira; zimagwiritsidwa ntchito pomwe pakufunika kuyatsa kapena kuzimitsa zowunikira kuchokera kumalo angapo, kuyatsa kapena kuzimitsa m'magulu, kapena kuyatsa kwapakati kapena kuzimitsa.
Tiyeni tikambirane mayankho angapo ofunikira ndi zopangira kuchokera pakuwona kulekerera zolakwika za Hardware, motero ntchito yeniyeni yayitali.
Chitsanzo cha njira yoyendetsera magetsi ambiri
Kuwongolera kwa Level 1 - magwero onse owunikira mnyumbamo, kuphatikiza omwe amayendetsedwa kuchokera kumalo angapo.
2 mlingo wa ulamuliro - magwero kuwala pamodzi gulu kumanzere mapiko a chipinda choyamba, magwero kuwala pamodzi gulu kumanja mapiko a chipinda choyamba, magwero kuwala pamodzi gulu kumanzere mapiko a chipinda chachiwiri, magwero a kuwala pamodzi mu gulu mu mapiko lamanja la yachiwiri yansanjika.
Kuwongolera kwa gawo 3 - zowunikira zophatikizidwira pagulu lonse loyamba, zowunikira zophatikizidwa mugulu lonse lachiwiri.
Kuwongolera kwa Level 4 - magwero owunikira ophatikizidwa kukhala gulu mnyumba yonse.
Mayankho omwe dongosolo lotere lingamangidwe
1.PLC.
2. Pulse relay.
3. Complex of Hardware Non-Programmable Logic (CTS NPL) yozikidwa pazida zowongolera zowunikira zomwe tapanga tokha.
Mutha kuwerenga za CTS NPL m'nkhaniyi .
Chipangizo chowongolera kuyatsa kwa electromechanical ndi gawo lowongolera lomwe limayikidwa pa njanji ya DIN ya 36 mm (ma module awiri).
Malamulo
Kuwongolera kumachitika pogwiritsa ntchito batani lachiwiri lomwe lili ndi ma adilesi awiri omwe amatseguka.
Chifukwa chopangira CTS NPL
Chifukwa cha chitukuko cha KTS NPL chinali luso la kasitomala, yemwe ankafuna kugwiritsa ntchito machitidwe oyendetsa magetsi opangira magetsi ambiri popanda kugwiritsa ntchito PLC (chifukwa kusunga ndi okwera mtengo kwambiri).
Chitsanzo cha magwiridwe antchito amitundu yambiri yowunikira kuyatsa mu kanyumba
Tiyeni tikambirane za dongosolo lololera zolakwika pogwiritsa ntchito zida zowunikira
Kupanga:
1. Zida zowunikira zowunikira.
Mtengo wa zida: $47 pa gwero limodzi lowala.
Kukhalitsa kwamagetsi: 100 mikombero ya AC-000.
Ngati chimodzi mwa zida zowunikira zowunikira sizigwira ntchito, zida zina zonse zowongolera zowunikira zidzapitilira kugwira ntchito.
Izi zikutanthauza kuti ngati chipangizo chowongolera chowunikira chikuwonongeka, kuunikirako kudzapitiriza kugwira ntchito, kupatulapo gwero limodzi la kuwala, kapena gulu limodzi losintha, pamene katswiri amaika zipangizo zatsopano ndikuziyika.
Ganizirani za dongosolo lolekerera zolakwika la PLC
Kupanga:
1. Programmable logic controller.
2. zosunga zobwezeretsera programmable logic controller.
3. Ma module a I/O.
4. Ma module a I / O osafunikira.
5. Chipangizo cha Redundancy (chimapereka kuwongolera kusintha kwa PLC zosunga zobwezeretsera ndi ma module a I / O osungira).
6. Kutumiza kwapakatikati.
7. Ma actuators (ma relay / ma contactor).
Mtengo wa zida: $237 pa gwero limodzi lowala.
Kukhalitsa kwamagetsi: 100 mikombero ya AC-000.
Ngati ma module a PLC kapena I / O alephera, chipangizo chosunga zobwezeretsera chidzasintha nthawi yeniyeni kupita ku PLC yosunga zobwezeretsera ndi ma module a I/O osunga zobwezeretsera ndikuwonetsa kulephera.
Izi zikutanthauza kuti ngati PLC ikuphwanyidwa, kuyatsa kudzapitirizabe kugwira ntchito pamene katswiri amaika zipangizo zatsopano ndikuziyika.
Ganizirani za dongosolo lopanda ntchito la PLC
Kupanga:
1. Programmable logic controller.
2. Ma module a I/O.
3. Kutumiza kwapakatikati.
4. Ma actuators (ma relay / ma contactor).
Mtengo wa zida: $69 pa gwero limodzi lowala.
Kukhalitsa kwamagetsi: 100 mikombero ya AC-000.
Ngati PLC kapena ma module olowetsa / zotulutsa alephera, kuyatsa kudzasiya kugwira ntchito mpaka katswiriyo akhazikitse ndikutumiza zida zatsopano.
Tiyeni tikambirane njira zodziwika bwino za PLC m'malo okhalamo
Kupanga:
1. Programmable logic controller
2. Ma module a I/O
3. Kupatsirana kwapakatikati kuti alowe
Mtengo wa zida: $41 pa gwero limodzi lowala.
Kukhalitsa kwamagetsi: 25 mikombero ya AC-000.
Ngati ma PLC kapena ma module olowetsa / otulutsa alephera (izi zidzachitika mwachangu kuposa m'matembenuzidwe akale, popeza kukana kwamagetsi kumatsika kanayi), kuyatsa kudzasiya kugwira ntchito mpaka katswiriyo akhazikitse ndikutumiza zida zatsopano.
Ganizirani kachitidwe kotengera ma pulse relay
Kupanga:
1. Pulse relay.
2. Ma module olamulira gulu.
3. Central control modules.
Mtengo wa zida: $73 pa gwero limodzi lowala.
Kukhalitsa kwamagetsi: 100 mikombero ya AC-000.
Ngati relay imodzi ikulephera, ma relay ena onse muulamuliro wowunikira adzapitiriza kugwira ntchito.
Izi zikutanthauza kuti ngati pulse relay ikasweka, kuyatsa kudzapitirizabe kugwira ntchito, kupatulapo gwero limodzi la kuwala, kapena kusintha kwa gulu limodzi, pamene katswiri amaika zipangizo zatsopano ndikuziyika.
Poyang'ana koyamba, ma pulse relays sali osiyana kwambiri ndi zida zowunikira, koma sizili choncho; ma pulse relays ali ndi zolephera zingapo:
1. Kuchepetsa kuchuluka kwa masinthidwe: 5-15 masinthidwe pamphindi / 100 masinthidwe patsiku.
2. Kuchepetsa kutalika kwa kugunda: 50 ms - 1 s.
3. Kugwedezeka kungayambitse kusintha kwachisawawa, ndiko kuti, ngati kuli kofunikira, sikungathekenso kukhazikitsa ma contactors mu kabati yolamulira.
4. Mukayatsa / kuzimitsa zolumikizirana moyandikana, mpweya wabwino ndi kuziziritsa kwa kabati yowongolera zitha kufunikira.
5. Pamene chiwerengero cha magawo olamulira chikuwonjezeka, zovuta zomangira dera zimawonjezeka.
Pomaliza
Dongosolo lololera zowunikira zamitundu ingapo lokhala ndi PLC lili ndi mtengo wokwera kwambiri kwa malo okhala, dongosolo lokhazikitsidwa ndi ma pulse relays lili ndi malire akulu, dongosolo lokhazikika pazida zowongolera zowunikira ndi njira yagolide.
