Abstract

A method for self-assessing components of a cargo handling system configured for autonomous control by a processor is disclosed. In various embodiments, the method includes receiving by the processor a sensor database from a plurality of sensing agents in operable communication with the processor; testing by the processor the plurality of sensing agents by comparing the sensor database against a sensor assessment; and performing by the processor a first calibration assessment of the plurality of sensing agents to assess whether a compromised operational status of the cargo handling system has occurred due to a failure of one or more of the plurality of sensing agents.

First claim

What is claimed:

1. A method for self-assessing components of a cargo handling system configured for autonomous control by a processor, comprising:
receiving, by the processor, sensor data from a plurality of sensing agents in operable communication with the processor;
testing, by the processor, the plurality of sensing agents by comparing the sensor data against a sensor assessment; and
performing, by the processor, a first calibration assessment of the plurality of sensing agents to assess whether an operational status of the cargo handling system has occurred due to a failure of one or more of the plurality of sensing agents based on the testing;
performing, by the processor, a first system assessment to determine whether a level of autonomous control should be modified based on the first calibration assessment; and
reducing, by the processor, the level of autonomous control of the cargo handling system in an event one or more of the plurality of sensing agents has at least one of faulted or failed.

2. The method of claim 1 , further comprising receiving, by the processor, actuator data from a plurality of actuators in operable communication with the processor.

3. The method of claim 2 , further comprising testing, by the processor, the plurality of actuators by comparing the actuator data against an actuator assessment.

4. The method of claim 3 , further comprising performing, by the processor, a second calibration assessment of the plurality of actuators to assess whether the operational status of the cargo handling system has occurred due to a failure of one or more of the plurality of actuators:
performing, by the processor, a second system assessment to determine whether the level of autonomous control should be modified based on the second calibration assessment; and
reducing, by the processor, the level of autonomous control of the cargo handling system in an event one or more of the plurality of sensing actuators has at least one of faulted or failed.

5. The method of claim 1 , further comprising determining, by the processor, whether a human is within a region of an aircraft envelope defined by the cargo handling system where one or more of the plurality of sensing agents has faulted or failed.

6. The method of claim 5 , further comprising performing, by the processor, a second system assessment to determine whether a level of autonomous control should be modified based on the human being within the region of the aircraft envelope.

7. The method of claim 6 , further comprising reducing, by the processor, the level of autonomous control of the cargo handling system in an event the human is within the region of the aircraft envelope.

8. The method of claim 1 , wherein the sensor data comprises a visual representation.

9. The method of claim 8 , wherein the first sensor assessment comprises a range of acceptable values of brightness.

10. The method of claim 1 , wherein the sensor data comprises an audio representation.

11. The method of claim 10 , wherein the first sensor assessment comprises a sound signal of known strength.

12. A cargo handling system configured for self-assessment and autonomous control, comprising:
a processor in operable communication with a plurality of sensing agents, the plurality of sensing agents configured to transmit a sensor data to the processor; and
an object database configured to store a sensor assessment for testing by the processor the plurality of sensing agents by comparing the sensor database against the sensor assessment, wherein the processor is configured to:
perform a first calibration assessment of the plurality of sensing agents to assess whether an operational status of the cargo handling system has occurred due to a failure of one or more of the plurality of sensing agents based on the testing,
perform a first system assessment to determine whether a level of autonomous control should be modified based on the first calibration assessment; and
reduce the level of autonomous control of the cargo handling system in an event one or more of the plurality of sensing agents has at least one of faulted or failed.

13. The cargo handling system of claim 12 , wherein the processor is configured to receive actuator data from a plurality of actuators in operable communication with the processor.

14. The cargo handling system of claim 13 , wherein the processor is configured to test the plurality of actuators by comparing the actuator data against an actuator assessment.

15. The cargo handling system of claim 14 , wherein the processor is configured to:
perform a second calibration assessment of the plurality of actuators to assess whether the operational status of the cargo handling system has occurred due to a failure of one or more of the plurality of actuators;
perform a second system assessment to determine whether the level of autonomous control should be modified based on the second calibration assessment; and
reduce the level of autonomous control of the cargo handling system in an event one or more of the plurality of sensing actuators has at least one of faulted or failed.

16. The cargo handling system of claim 12 , wherein the processor is configured to determine whether a human is within a region of an aircraft envelope defined by the cargo handling system where one or more of the plurality of sensing agents has faulted or failed.

17. The cargo handling system of claim 16 , wherein the processor is configured to perform a second system assessment to determine whether a level of autonomous control should be modified based on the human being within the region of the aircraft envelope.

18. The cargo handling system of claim 17 , wherein the processor is configured to reduce the level of autonomous control of the cargo handling system in an event the human is within the region of the aircraft envelope.
