Monitoring and voting in asynchronous sampling
Abstract
A method for treating monitoring and voting for quad-redundant, asynchronous signals is described. Each pair of signals is compared to determine whether or not they are in tolerance, and the signal state and fault pattern are determined based on the results of the comparisons. Keys of movement between the fault patterns are derived and used to devise monitoring algorithms for determining the set of redundant signals that should be used by the voter.
