1. A method of monitoring structural health of a tensile strength member, comprising:
providing a plurality of intelligent modules, each respective intelligent module coupled to the tensile strength member at a distance from one another along a length of the tensile strength member;
providing a data collection and analysis system;
providing an intelligent module location system, configured to determine location information for each of the intelligent modules at a corresponding time value, and send the location information and the corresponding time value to the data collection and analysis system;
each of the modules configured to measure a vibration at a corresponding time value, and send vibration information corresponding to the vibration and the corresponding time value to the data collection and analysis system;
the data collection and analysis system using the vibration information, the location information, and the corresponding time values for the intelligent modules to determine a baseline state for a first parameter characterizing the structural health of the tensile strength member;
the data collection and analysis system continuing to collect the vibration information, the location information, and the corresponding time values to determine a current state for the first parameter; and
the data collection and analysis system determining a current state of health for the tensile strength member by determining a difference between the current state for the first parameter and the baseline state for the first parameter.
