Abstract

A method for performing a safety assessment of a cargo handling system controlled by a processor and having a plurality of sensing agents is disclosed. In various embodiments, the method includes receiving by the processor a run-time database from the plurality of sensing agents, the run-time database including data from which a positioning of a plurality of objects on the cargo handling system may be determined; generating by the processor a mapping of the positioning of the plurality of objects; validating by the processor whether a run-time state of the cargo handling system is in violation of a safety protocol; and determining by the processor whether to implement a corrective action.

First claim

What is claimed is:

1. A method for performing a safety assessment of a cargo handling system controlled by a processor and having a plurality of sensing agents, comprising:
receiving, by the processor, a run-time database from the plurality of sensing agents, the run-time database including video data and audio data from which a trajectory of a plurality of objects on the cargo handling system is determined, wherein the plurality of objects includes a first unit load device and a second unit load device and wherein the audio data is at least one of a sound measurement in decibels or an audio stream;
generating, by the processor, a mapping of the trajectory of the plurality of objects;
validating, by the processor, whether a run-time state of the cargo handling system is in violation of a safety protocol;
determining, by the processor, whether to implement a corrective action; and
responsive to determining that the corrective action is to be implemented, instructing, by the processor, the cargo handling system to slow or to halt a translation along a conveyance surface of the cargo handling system of at least one of the first unit load device or the second unit load device.

2. The method of claim 1 , wherein generating by the processor the mapping of the trajectory of the plurality of objects includes predicting a future state of the first unit load device and the second unit load device.

3. The method of claim 2 , wherein predicting the future state of the first unit load device includes multiplying a first run-time velocity by a time step to obtain a future location of the first unit load device and predicting the future state of the second unit load device includes multiplying a second run-time velocity by the time step to obtain the future location of the second unit load device.

4. The method of claim 3 , wherein the violation of the safety protocol occurs if the processor determines an overlap between a first object space surrounding the first unit load device and a second object space surrounding the second unit load device at the future state.

5. The method of claim 1 , wherein the plurality of objects includes a unit load device and a wall of an aircraft envelope, the cargo handling system being housed within the aircraft envelope.

6. The method of claim 5 , wherein generating by the processor the mapping of the trajectory of the plurality of objects includes predicting a future state of the unit load device with respect to the wall.

7. The method of claim 6 , wherein predicting the future state of the unit load device includes multiplying a run-time velocity by a time step to obtain a future location of the unit load device with respect to the wall.

8. The method of claim 7 , wherein the violation of the safety protocol occurs if the processor determines an overlap between an object space surrounding the unit load device and the wall.

9. The method of claim 7 , wherein the corrective action includes instructing, by the processor, the cargo handling system to slow or to halt a translation along a conveyance surface of the cargo handling system of the unit load device.

10. The method of claim 1 , wherein the plurality of objects includes a unit load device and a human with an aircraft envelope, the cargo handling system being housed within the aircraft envelope.

11. The method of claim 10 , wherein generating by the processor the mapping of the trajectory of the plurality of objects includes predicting a future state of the unit load device with respect to the human.

12. The method of claim 11 , wherein predicting the future state of the unit load device includes multiplying a run-time velocity by a time step to obtain a future location of the unit load device with respect to the human.

13. The method of claim 12 , wherein the violation of the safety protocol occurs if the processor determines an overlap between an object space surrounding the unit load device and the human.

14. The method of claim 13 , wherein the corrective action includes instructing, by the processor, the cargo handling system to slow or to halt a translation along a conveyance surface of the cargo handling system of the unit load device.

15. A cargo handling system configured for autonomous control, comprising:
a processor in operable communication with a plurality of sensing agents, the plurality of sensing agents configured to transmit a run-time database from the plurality of sensing agents, the run-time database including video data and audio data from which a trajectory of a plurality of objects on the cargo handling system is determined,
wherein the plurality of objects includes a first unit load device and a second unit load device,
wherein the audio data is at least one of a sound measurement in decibels or an audio stream,
wherein the processor is configured to generate a mapping of the trajectory of the plurality of objects, validate whether a run-time state of the cargo handling system is in violation of a safety protocol, determine whether to implement a corrective action, and, responsive to determining that the corrective action is to be implemented, slow or to halt a translation along a conveyance surface of the cargo handling system of at least one of the first unit load device or the second unit load device.

16. The cargo handling system of claim 15 , wherein the processor is configured to predict a future state of the plurality of objects by multiplying a run-time velocity by a time step for the plurality of objects to obtain a future location of the plurality of objects.

17. The cargo handling system of claim 16 , wherein the processor is configured to determine an overlap between a first object space surrounding a first object of the plurality of objects and a second object space surrounding a second object of the plurality of objects.
