1. A method for operating a structural health management system comprising:
- gathering data from a first zone of sensors and a second zone of sensors, each of the sensors mounted on a test material;
sending data from at least a first subset of sensors of the first zone of sensors to a first sensor data collector;
sending data from at least a first subset of sensors of the second zone of sensors to the first sensor data collector;
sending data from a second subset of sensors of the first zone of sensors to a second sensor data collector;
sending data from the first subset of sensors of the first zone to a processor from the first sensor data collector;
sending data from the second subset of sensors of the first zone to the processor from the second sensor data collector;
comparing the data from the first sensor data collector and the second sensor data collector; and
indicating a possible error condition indicative of a defective sensor if the data from the first sensor data collector and the data from the second sensor data collector differ by a predetermined amount.

Abstract
A structural health management system is disclosed. The structural health management system comprises a zone of sensors. A first sensor data collector is coupled to a first subset of the sensors in the zone; and a second sensor data collector coupled to a second subset of the sensors in the zone. In the present invention, loss of a sensor data collector does not result in the loss of ability to perform nondestructive testing in an entire zone.
