TRANSITION DETECTION METHOD FOR AUTOMATIC-SETUP NON-INTRUSIVE APPLIANCE LOAD MONITORING

摘要

According to a first aspect, the invention relates to a method (51) for detecting transitions and comprising the steps of: generating a residual signal, a, from a measured signal and providing rules concluding that transitions occur when the residual signal,a, is larger than a threshold value ?. The residual signal, a, has a high amplitude when transitions occur and a low amplitude in the other cases. The method (51) is characterized in that the threshold value ? is automatically defined from local values of the residual signal.
