Abstract:
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.
