There are many difficulties associated with the design and implementation of on-line Prognostic Health Management (PHM) systems, including the tardy specification of requirements late in the design cycle, insufficient or conflicting input from pertinent stakeholders, difficult or costly access to domain knowledge, degree of difficulty in validating and testing functionality, and an illspecified and mostly uncoordinated process.

The integration of structural health monitoring (SHM) systems into in-service applications has been hindered by the implied infrastructure, specifically wires for power and data from each sensor an acquisition and/or processing unit. Prior research by the present investigators has demonstrated a patented method of point-of-measurement datalogging for SHM, thereby greatly reducing the required quantity of cable by locally converting analog signals into digital data that can be placed on a common sensor-bus.
