Aircraft interior monitoring

摘要

A system for monitoring an aircraft interior may include a multiplicity of sensors each placed at a selected location of a plurality of locations within the aircraft interior. Each sensor is configured to monitor a condition in an associated area of the aircraft interior. The system may also include a server onboard the aircraft. The onboard server is configured to receive data from each of the multiplicity of sensors and to control operation of each of the multiplicity of sensors. The system may also include a router onboard the aircraft. The onboard router is configured to communicate with a router off-board the aircraft and to transfer data from the onboard server to the off-board router. The off-board router is associated with a ground monitoring facility that is configured to analyze data from each of the multiplicity of sensors, check or compare the data to reference data and depending upon any levels being exceeded an appropriate alert may be generated.

1. A system for monitoring an aircraft interior, comprising:
a multiplicity of sensors each placed at a selected location of a plurality of locations within the aircraft interior, each sensor being configured to monitor a condition in an associated area of the aircraft interior; a server onboard the aircraft, the onboard server being connected to the multiplicity of sensors and being configured to receive data from each of the multiplicity of sensors and to control operation of each of the multiplicity of sensors; and a router onboard the aircraft, the onboard router being connected to the onboard server and the onboard router being configured to communicate with a router off-board the aircraft and to transfer data from the onboard server to the off-board router, wherein the off-board router is associated with a ground monitoring facility that is configured to analyze data from each of the multiplicity of sensors; and an off-board database associated with the ground monitoring facility, wherein the data from the multiplicity of sensors is stored in the off-board database, the off-board database comprising a reference table configured to store the data from each of the multiplicity of sensors that is within limits and an exceedance table to store data from the multiplicity of sensors that exceeds a predetermined threshold, wherein the ground monitoring facility is configured to perform a method comprising:
comparing new data from each sensor to previously stored data for the sensor in the reference table;storing the new data in the reference table in response to the data not exceeding the predetermined threshold;storing the new data in the exceedance table in response to the new data exceeding the predetermined threshold;acquiring additional samples of new data from a particular sensor in response to the new data from the particular sensor exceeding the predetermined threshold;comparing each additional sample of new data from the particular sensor to previously stored data in the reference table;comparing each additional sample of new data from the particular sensor to previously stored data in the exceedance table to confirm that an anomaly persists in response to a dissimilarity between each additional sample of new data and the previously stored data in the reference table; andgenerating an alarm in response to the anomaly persisting and the additional samples of new data from the particular sensor exceeding the predetermined threshold for a preset number of samples of the additional samples of new data from the particular sensor or expiration of a preset time period.
