Abstract

The present invention provides a method and device for abnormality detection of aircraft telemetry data, relating to the technical field of data processing, including: obtaining pilot telemetry data sent by the aircraft, and determining whether the pilot telemetry data is a stationary time series through stationarity detection; After the stationarity detection, obtain the telemetry data of the node at the current moment sent by the aircraft; if the pilot telemetry data is a stationary time series, use the boundary detection algorithm to detect the telemetry data of the node at the current moment to determine whether the telemetry data of the node at the current moment is abnormal data; if the pilot telemetry data is not a stationary time series, then use the preset detection algorithm to detect the telemetry data of the node at the current moment to determine whether the telemetry data of the node at the current moment is abnormal data, which solves the problem of telemetry data in the prior art The detection steps of abnormal data detection are complicated and the detection accuracy is low.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to an abnormal detection method and device for aircraft telemetry data. Background technique [0002] For satellite telemetry, the rapid transient changes in the space environment and the noise of equipment lines will bring noise interference to signal acquisition, so that the telemetry data will be doped with randomly distributed abnormal data. The development has brought great difficulties. [0003] In the prior art, algorithms such as boundary detection algorithm, trend prediction algorithm, rate constraint algorithm, and density (distance) detection algorithm are generally used to detect anomalies in telemetry data, but the detection steps of the above methods are complicated and the detection accuracy is low. [0004] For the above problems, no effective solution has been proposed yet. Contents of the invention [0005] In view of this, the object of the present inv...
