Wireless sensor network for performance monitoring of electrical machine

To avoid unexpected equipment failures and obtain higher accuracy in diagnostic and prognostic for the health condition of a motor, efficient and comprehensive data collecting, monitoring, and control play an important role to improve the system more reliable and effective. A novel wireless data collection for health monitoring system of electric machine based on wireless sensor network (ZigBee™/IEEE802.15.4 Standard) is proposed and developed in this paper. The unique characteristics of ZigBee networks such as low power, low cost, and high flexibility make them ideal for this application. As the focus of this paper, the hardware design and implementation of a multiple nodes Zigbee based wireless sensor network are discussed. The communication protocol and software design for both wireless sensor network node and base station based on the CC2430 system on chip are presented in detail. Experimental results of the proposed wireless sensor network for its applicability to investigate different operating conditions such as electrical faults and mechanical faults are investigated and discussed.
