Abstract
A hierarchical fault handling system and method based on filtering data regarding entities in the system and coordinating said filtered data in order to determined if an entity is considered faulty or not. The result for all entities is coordinated in a system fault coordinating means (17) which makes the overall decision if the system considered to be faulty or not.
Claims30
A supervising system for supervising the function of an assembly comprising a number of interworking parts, said system comprising
- At least a first detector for detecting a physical property of an entity of the system and providing measurement data about the physical property;
- At least a first determining means for determining the status of said entity;
- said supervising system comprising filter means arranged to receive measurement data from the at least first detector, filter said measurement data and output a signal indicating if said entity is faulty in dependence of said filtered measurement data;
- and
- in that the determining means is arranged to receive said output signal from a least a first and a second filter means, co-ordinate said output signals and, on the basis of said co-ordination, determine whether a fault report should be generated for the entity.
A method for supervising the function of an assembly comprising a number of interworking parts, comprising the following steps:
- defining at least one entity of the system that is to be supervised;
- detecting at least one physical property of the entity as at least one measured value;
- filtering the at least one measured value;
- determining whether or not the entity is faulty on the basis of the filtered value.
