A method including receiving a data packet over a network, the data packet having a size. The method also includes parsing the data packet into a header and a body. The method also includes identifying a protocol type from the header and the size. The method also includes identifying a signal characteristic of signal data in the body. The method also includes identifying a classification of a source sensor which generated the data packet based on the protocol type and the signal characteristic. The method also includes generating a metadata file based on the source sensor. The method also includes labeling the data packet with the metadata file to form a labeled data packet.

System and device to automatically identify data tags within a data stream

A configuration manager is associated with a Networked Control System (NCS) comprising a plurality of sensors and actuators. The configuration manager automatically discovers the hardware and/or software configurations of the sensors and actuators, and analyzes that information in order to detect whether any of the sensors and actuators have been tampered with. Provided the configuration manager detects such tampering, the configuration manager indicates the tampering to a control manager of the NCS, which then functions to minimize potential damage to the NCS.

Automatic tampering detection in networked control systems

An example method includes receiving a plurality of data streams acquired for a respective parameter of a plurality of parameters indicating an operating condition of the aircraft, selecting at least one data stream corresponding to at least one parameter of the respective plurality of parameters, selecting a portion of data from the at least one data stream, comparing the portion of data to a model determined for the at least one parameter based on historical data, determining that a failure has occurred or is likely to occur during operation of the aircraft based on the comparing, and transmitting aircraft health monitoring information indicative of occurrence or likelihood of occurrence of the failure.

Real time streaming analytics for flight data processing

A computer-implemented method, environmental control system, and aircraft are provided. Environmental operating conditions data for a heat exchanger is received. Measured values from sensors measuring parameters of the heat exchanger are also received. An operating model for the heat exchanger based on the received environmental operating conditions is retrieved from a first data structure. The retrieved model includes estimated values for the sensors. A difference between the estimated values and the measured values is calculated. The calculated differences are compared to at least one threshold value. Upon the differences exceeding the at least one threshold value, the calculated differences are compared to abnormal operation models in an abnormal operation library data structure. Upon the calculated difference matching an abnormal operation model in the abnormal operation library data structure, outputting an abnormal operation identity associated with the abnormal operation model. If there is no match, a learning process develops a new model for a new abnormal operation.
