Remote Health Monitoring for Asset Management

Figure 5.8. 3-D graph showing sensor array behavior in the laboratory.
The laboratory testing established the operation of the sensor array and served as a platform for
developing the necessary software to monitor the sensor array. Following the laboratory testing,
field installation of the test pile was initiated. The following sections describe the elements of
the field installation process.
Site Selection
To test the functional operation and installation of the test pile, a field test site was selected to
install the pile for monitoring. Following discussions with the technical panel, it was decided
that the installation of the pile in a nearby stream would be a suitable demonstration of the
functionality of the array. A field test site in close proximity to the University of Missouri was
explored to provide convenient access for researchers. This was necessary because of the
prototype nature of the sensor system and to enable troubleshooting and allow for modifications
to be made rapidly. The characteristics of the test site that was sought were as follows:
•
•
•
•
120 volt AC power
Easy access for equipment to install the pile
Sufficient water level to demonstrate the operation of the pile
Close proximity to the University
After surveying the local area and meeting with campus facilities personnel, it was determined
that a USDA research station located adjacent to the University campus met the requirements for
installing the test pile. The test location area is shown in Figure 5.9. The location includes
