Machine Condition Monitoring with Industrial Wireless Sensor Networks
Neil W. Bergmann, Liqun Hou · 2013
This chapter reviews the industrial wireless sensor networks (IWSNs) application cases, including the general application cases and commercial systems. It summarizes the system requirements for IWSN monitoring systems. The chapter demonstrates the tension between the higher system requirements of industrial monitoring and the resource constrained characteristics of IWSN nodes by reviewing the case of induction motor condition monitoring. It explores three industrial wireless network standards, ZigBee, WirelessHART, ISA100.11a, and several protocols developed by individual researchers for IWSNs and investigates on-sensor data processing to address this tension. The chapter also presents a novel IWSN with on-sensor data processing for induction motor condition monitoring for verification. It reviews energy harvesting for IWSNs as another way for prolonging node lifetime. A wireless sensor node is characterized by its small size, its ability to sense environmental phenomena through a set of transducers and a radio transceiver with autonomous power supply.
