Abstract
A monitoring system for a support structure is provided. The monitoring system may include a resistance circuit coupled to the support structure, and an interface circuit coupled to the resistance circuit. The resistance circuit may include a first set of resistors and a second set of resistors, wherein the second set of resistors is configured to provide a reference voltage. The interface circuit may include one or more comparators, wherein each comparator is configured to compare a voltage across at least one of the resistors with the reference voltage and generate an output signal corresponding to the comparison. The interface circuit may be configured to continuously monitor an effective resistance of the support structure based on the output signals.
