Abstract
Abstract A remote monitoring diagnostic system and method utilize two different storage techniques. A time-coherent storage technique and change-detect storage technique are utilized to ensure that sensor signals are stored accurately and efficiently. A central diagnostic system can poll or pull the sensor values remotely. Additionally, an on-site monitor can perform anomaly detection to generate malfunction data.
