Application study on prognostics and health management of armored equipment based on wireless sensor networks

With the rapid development of prognostics and health management (PHM) technologies particularly for armored equipment, the on-line distributed collection and wireless transmission of the monitoring data has become a demanding question for the researchers. Wireless sensor networks (WSNs) provide a newly measure for data acquisition of the PHM system for armored equipment, with its features of small size, simple layout and wireless transmission. This paper discusses the key factors in the design of PHM based on WSNs, proposes the WSNs-based framework and scheme for PHM data transfer focusing on the power transmission assembly of armored equipment, specifies the design of relevant modules and makes suggestions about the future researches.
