Method and Apparatus for Detecting Performance of an APU Starter

摘要

Abstract The present invention relates to a method for detecting performance of an APU starter, comprising: obtaining APU-related messages at multiple time points within one time period; obtaining running parameters of the s APU starter according to the messages, the running parameters comprise starting time STA; calculating average value AVG and deviation index 5 of the starting time within said time period; determining whether performance of the APU starter is in a stable phase, decline phase or failure phase according to the deviation index 5.
