Ta Yaya Tsarin Kula da Tsaro na Zamani Ke Ƙara Ingancin PLC da DCS?
Cigaban Kula da Tsaro a Harkar Kera Masana’antu ta Zamani
Na’urorin sarrafa masana’antu (industrial automation) suna dogaro da ƙarfafan tsarin kulawa don tafiyar da tsari mai rikitarwa. Programmable Logic Controllers (PLC) da Distributed Control Systems (DCS) sun wuce matakin kasancewa masu warware sauƙaƙan lissafi kaɗai. Yanzu suna zama cikakkun layukan tsaro da ke ci gaba da sa ido kan injuna, ma’aikata, da yanayin muhalli. Yayin da masana’antu ke neman ƙarin inganci, dole ne tsarin tsaro ya amsa cikin milisekan—safety PLC na zamani na kammala tsarin rufewa na gaggawa cikin ƙasa da milisekan 100, wanda ke hana matsala ta tsananta.
Yayin da masana’antu ke rungumar Industry 4.0, tsarin kulawar tsaro yanzu yana haɗa hasashen bayanai (predictive analytics). Sensors suna tura bayanai na ainihi (real-time data) zuwa dandalin DCS, wanda ke nazarin yanayi tare da gano abin mamaki kafin su zama matsala mai tsanani. Wannan dabarar mai sa ido tun kafin faruwar matsala (proactive) tana rage haɗarin haɗura ƙwarai.

PLC da DCS: Rawar Bambance-Bambance Amma Masu Cika Juna a Rage Haɗari
Duk PLC da DCS na kula da tsaro, amma suna aiki ne a ma’aunin aikace-aikace daban-daban. PLCs suna matuƙar dacewa da ayyuka masu sauri kuma na sassa-sassa (modular), kamar tsarin emergency stop da kare injina a matakin na’ura ɗaya. A gefe guda, tsarin DCS suna kula da ci gaba da tsari a duk fadin masana’anta, suna sarrafa ɗarurruwan control loop tare da haɗa tsarin ƙararrawa (alarm handling). Don haka, zaɓar dandali da ya dace ya dogara ne da irin rikitarwar tsari da Safety Integrity Level (SIL) da ake buƙata.
Baya ga haka, tsarin haɗaɗɗu na zamani suna haɗa saurin PLC da tsarin rabon DCS. Misali, safety instrumented systems (SIS) sau da yawa suna amfani da PLCs da aka ba su takardar shaida ta SIL waɗanda ke sadarwa kai tsaye da cibiyar sadarwar DCS. Wannan tsarin layuka da yawa na tsaro yana tabbatar da cewa idan ɗaya ya gaza, na madadin zai ci gaba da sarrafawa, ta haka ana samun redundancy ba tare da rasa inganci ba.
