Gas House Autonomous System Monitoring (GHASM)

Metadata Updated: May 2, 2019

This project involves the development of an autonomous monitoring system capable of assessing the condition of every element in the system, continuously and comprehensively. The Gas House Autonomous System Monitoring (GHASM) will be an intelligent knowledge system making inferences and conclusions on the state of system elements i.e., sensors, valves. [HTML_REMOVED]Knowledge will be integrated across elements and subsystems to implement functional capabilities of an Integrated System Health Management (ISHM). These capabilities include (1) anomaly detection, (2) diagnostics, (3) prognostics, and (4) user interfaces to provide the operator with an integrated awareness about the system[HTML_REMOVED]s health.The GHASM Project[HTML_REMOVED]s objective is to implement a knowledge-based capability that autonomously monitors and captures anomalies in the system. The implementation is targeted for the new hydrogen system within the High Pressure Gas Facility (HPGF) or Gas House at NASA[HTML_REMOVED]s Stennis Space Center (SSC). The technology has been evolving for approximately 8 years at SSC. It consists of a software toolkit built using the Commercial off-the-shelf (COTS) Gensym G2 software platform. In the past 3 years, the technology has been validated at KSC[HTML_REMOVED]s Cryogenic Testbed Laboratory. This will be the first implementation on an operational system.
