Abstract

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.

5. The system of claim 1, further comprising a data over power line interface associated with the onboard router for communication with the off-board router, wherein the onboard router is connectable to the off-board router by a power line that supplies power to the aircraft when the aircraft is parked at a gate at an airport.

6. The system of claim 1, further comprising a data over power line communications interface and a wireless communications interface associated with each of the onboard router and the off-board router for communications between the routers, wherein the onboard router is connectable to the off-board router by either a wired communications link via the data over power line communications interfaces or a wireless communications link via the wireless communications interfaces.

7. The system of claim 1, wherein the onboard server is configured to activate each sensor to monitor the condition in the associated area of the aircraft interior in response to a set of signals comprising a first signal indicating a weight on wheels configuration of the aircraft and a second signal indicating a parked configuration or zero velocity condition of the aircraft.

8. The system of claim 7, wherein the onboard server is configured to activate each sensor in a cargo area of the aircraft in response to the set of signals comprising the first signal, the second signal and a third signal indicating an opening of a door to the cargo area, the onboard server being configured to deactivate each sensor in the cargo area in response to a fourth signal indicating each door to the cargo area being closed.

9. The system of claim 1, wherein the onboard server is further configured to establish network connectivity to the ground monitoring facility by performing a method comprising:

receiving, by the onboard server, an internet protocol (IP) address from an off-board server;

establishing the onboard server as an endpoint with an off-board communications network;
