Wireless Sensors in Industrial Time-Critical Environments [Paperback]

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.

Introduction.- Industrial Control Systems: Concepts, Components and Architectures.- Distributed Control System Operations.- Industrial Protocols and Planning Considerations.- Scheduling of Wireless Sensor Networks.- Latency Modeling for Distributed Control Systems with Wired and Wireless Sensors.- Planning for Distributed Control Systems with Wired and Wireless Sensors.- Performance and Debugging.- Application Scenario: An Industrial Case Study.- Network Configuration: Example.- Network Layout: Example.- Evaluation of Planning and Monitoring Approaches: Details.

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.
