چکیده

∗ Author of correspondence, Phone: (301) 405-5278, Email:[email protected] ABSTRACT Data collection is an essential part of prognostics and health monitoring, and often requires the use of sensor systems to measure environmental and operational parameters. In this paper, the considerations for sensor system selection for prognostics and health monitoring implementation are discussed and some state-of-the-art sensor systems for prognostics are described. Finally, emerging trends in sensor system technologies are presented.

Embedded Prognostics Health Monitoring

The Pacific Northwest National Laboratory (PNNL) has conducted R&D for the US Army on prognostics health monitoring (PHM). The main focus of the work was to demonstrate the feasibility of developing an onboard PHM system for the gas turbine engine used on the M1 Abrams tank. Research was performed on methods for real time, onboard prognostics/engine life expectancy forecasting, and a prototype ...

Sensor Systems for Prognostics and Health Management

Prognostics and health management (PHM) is an enabling discipline consisting of technologies and methods to assess the reliability of a product in its actual life cycle conditions to determine the advent of failure and mitigate system risk. Sensor systems are needed for PHM to monitor environmental, operational, and performance-related characteristics. The gathered data can be analyzed to asses...

Effective Sensor Selection and Data Anomaly Detection for Condition Monitoring of Aircraft Engines

In a complex system, condition monitoring (CM) can collect the system working status. The condition is mainly sensed by the pre-deployed sensors in/on the system. Most existing works study how to utilize the condition information to predict the upcoming anomalies, faults, or failures. There is also some research which focuses on the faults or anomalies of the sensing element (i.e., sensor) to e...
