Wireless Sensors in Industrial Time-Critical Environments

This book introduces the components, operations, industry protocols and standards of distributed control system (DCS), and shows how to include wireless technology in their design while guaranteeing the desired operation characteristics.

This book introduces the fundamentals of DCS, and shows how to include wireless technology in their design while guaranteeing the desired operation characteristics. The text also presents insights and results gained from extensive practical experience in implementing and testing systems within a specific industrial setting. Features: examines the operations that the DCS implements, covering human-machine interfaces, diagnostics and maintenance interfaces, and controllers; discusses industrial control system and wireless network protocols; reviews scheduling in wireless sensor networks; describes a latency model for heterogeneous DCS with wired and wireless parts, that predicts monitoring, command, and closed loop latencies; explains how to plan operation timings systematically; introduces measures and metrics for performance monitoring and debugging, and describes how to add these to a system; presents experimental results to validate the planning approach, based on an application test-bed.

Explains how to provide operation time guarantees in heterogeneous distributed control systems with wireless sensor components Describes how to integrate wireless sensors and wireless sensor networks into standard industrial systems Offers advice on planning industrial distributed control systems

Klappentext

Modern industrial systems are often highly automated, with hundreds or even thousands of sensors and actuators monitoring the various processes, overseen by a distributed control system (DCS). Such control systems increasingly make use of wireless communications, yet these must still satisfy all safety-critical requirements.

This unique text introduces the components, operations, industry protocols and standards of DCS, and shows how to include wireless technology in their design while guaranteeing the desired operation characteristics. The book not only discusses the theory, but also presents insights and results gained from extensive practical experience in implementing and testing systems within a specific industrial setting.

Topics and features:

• Reviews the concepts, components and architectures supporting DCS
• Examines the operations that the DCS implements, covering human-machine interfaces, diagnostics and maintenance interfaces, and controllers
• Discusses industrial control system and wireless network protocols
• Reviews scheduling in wireless sensor networks
• Describes a latency model for heterogeneous DCS with wired and wireless parts, that predicts monitoring latencies, command latencies and closed loop latencies
• Explains how to plan operation timings systematically
• Introduces measures and metrics for performance monitoring and debugging, and describes how to add performance monitoring and debugging to asystem
• Presents experimental results to validate the planning approach, based on an application test-bed

This practical guide for real-world implementation will be of considerable interest to a wide audience, from professional engineers to researchers and students. It is suitable as a supporting text for courses covering industrial systems, networks, real-time systems, wireless sensor networks or embedded systems.
