Design of modern monitoring systems for efficient control andmanagement of technological processes

摘要

Proliferation of new and upgrade of existing industrial technologies is impossible without the development of efficientsystems and algorithms of automatic control of technological processes that rely on modern monitoring approaches.Typically, the monitoring tools, which include various sensors and other devices, have to be tightly integrated withautomatic control systems of industrial processes to reduce service expenses and downtime, increase capacity andoptimize production as a whole. While designing technological and automation lines, it is necessary to carefully selectparameters to be monitored such that optimal operation is achieved. At the same time, every step of industrial productionhas to be monitored to assure that each particular process is properly executed and resources are utilized in an efficientmanner. An example presented in this paper is based on an ac electric drive equipped with control and monitoringsystems. The result of a properly designed monitoring system is a simplified architecture of the control devices. Theoverall method can be implemented on the basis of a microprocessor, which offers several advantages including thepossibility of designing intelligent control loops, expanding the fault-tolerant range of operation, extending the resourceof operation, and coordinating interaction between different systems.
