Abstract

A system for on-board anomaly resolution for a vehicle has a data repository. The data repository stores data related to different systems, subsystems, and components of the vehicle. The data stored is encoded in a tree-based structure. A query engine is coupled to the data repository. The query engine provides a user and automated interface and provides contextual query to the data repository. An inference engine is coupled to the query engine. The inference engine compares current anomaly data to contextual data stored in the data repository using inference rules. The inference engine generates a potential solution to the current anomaly by referencing the data stored in the data repository.

Claims

1. A system for on-board anomaly resolution for a vehicle comprising:

a data repository for storing data related to different systems, subsystems, and components of the vehicle, wherein the data is encoded in a treebased structure, wherein the data repository is an expert system, the expert system storing a rulebase, wherein the data is run through the rulebase and a potential course of action is generated;

a query engine coupled to the data repository for providing a user and automated interface to provide contextual query to the data repository; and

an inference engine coupled to the query engine for comparing current anomaly data to the data stored in the data repository using inference rules, the inference engine cycles through the inference rules generating a potential solution to the current anomaly by referencing the data stored in the data repository.

2. A system for on-board anomaly resolution for a vehicle in accordance with claim 1 further comprising a documentation unit coupled to the data repository to load data into the data repository.

3. A system for on-board anomaly resolution for a vehicle in accordance with claim 2 further comprising a translation unit coupled to the documentation unit and the data repository to convert data for storage in the data repository.

4. A system for onboard anomaly resolution for a vehicle in accordance with claim 3 wherein the translation unit comprises:

a natural language processing (NLP) unit coupled to the documentation unit; and

a translator coupled to the NLP unit to provide a text based way to describe and apply a tree-based structure to the data.

5. A system for on-board anomaly resolution for a vehicle in accordance with claim 1 further comprising a communication device coupled to the query engine to communicate the potential solution to the current anomaly generated by the inference engine.

6. A system for on-board anomaly resolution for a vehicle in accordance with claim 5 wherein the communication device is one of a display mechanism and an automated control device located in an aircraft.

7. A system for on-board anomaly resolution for a vehicle in accordance with claim 5 wherein the communication device is located in at least one of an aircraft, command center, and vendor.

8. A system for on-board anomaly resolution for a vehicle in accordance with claim 1 wherein the inference engine comprises:

a match rules unit that locates all rules that are satisfied by the current date entered into the query engine;

a select rules unit coupled to the match rules unit that applies a selection strategy to determine which rules will be executed; and

an execute rules unit coupled to the select rules unit that executes the selected rules.

9. A system for on-board anomaly resolution for a vehicle in accordance with claim 1 further comprising control logic coupled to the inference engine to set search parameters of the inference engine.

10. A system for onboard anomaly resolution for a vehicle comprising:

a data repository for storing data related to different systems, subsystems, and components of the vehicle, wherein the data repository is an expert system, the expert system storing a rulebase, wherein the data is run through the rulebase and a potential course of action is generated;

a query engine coupled to the data repository for providing a contextual query interface;
