Abstract

Abstract A real-time data management system which uses data generated at different rates, by multiple heterogeneous incompatible data sources. In one embodiment, the invention is as an airport surface traffic data management system (traffic adviser) that electronically interconnects air traffic control, airline, and airport operations user communities to facilitate information sharing and improve taxi queuing. The system uses an expert system to fuse data from a variety of airline, airport operations, ramp control, and air traffic control sources, in order to establish, predict, and update reference data values for every aircraft surface operation.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 245 words
A real-time surface traffic management, knowledge-based, expert advisor system for optimizing airport operational efficiency by acquiring, fusing, interpreting, mining and displaying real-time predictive and processed data for surface traffic management or training simulations comprising: an intelligent server; a plurality of input sources connected to said intelligent server via communication links; and, a plurality of destination sources connected to said intelligent server via said communication links, for allowing users to access said real-time predictive and processed data; said intelligent server comprising: a) an input management subsystem, comprised of autonomous computer programs, which collects heterogeneous, incompatible data from multiple sources, including user or instructor provided data, manages data sources, initiates actions in response to events, and communicates and negotiates through said expert advisor system, without direct human control, b) an information subsystem which is a receiver of data from said input management subsystem and said user or instructor, a data fuser and integrator of said data, and an information router to the subsystems of said expert advisor system, c) a prediction subsystem, which is an information receiver from said information subsystem, comprising data fusion rules for providing, accuracy assessments, future surface event predictions, and provision of said predictions back to said information subsystem, d) a client interface subsystem which is a provider of displayed data to the destination sources, and e) an autonomous executive subsystem which is a start-up and control system for said intelligent server, an error recovery and message system, and a system health monitor.
Claim 2
Dependent Claim 245 words
A real-time surface traffic management, knowledge-based, expert advisor system for optimizing airport operational efficiency by acquiring, fusing, interpreting, mining and displaying real-time predictive and processed data for surface traffic management or training simulations comprising: an intelligent server; a plurality of input sources connected to said intelligent server via communication links; and, a plurality of destination sources connected to said intelligent server via said communication links, for allowing users to access said real-time predictive and processed data; said intelligent server comprising: a) an input management subsystem, comprised of autonomous computer programs, which collects heterogeneous, incompatible data from multiple sources, including user or instructor provided data, manages data sources, initiates actions in response to events, and communicates and negotiates through said expert advisor system, without direct human control, b) an information subsystem which is a receiver of data from said input management subsystem and said user or instructor, a data fuser and integrator of said data, and an information router to the subsystems of said expert advisor system, c) a prediction subsystem, which is an information receiver from said information subsystem, comprising data fusion rules for providing, accuracy assessments, future surface event predictions, and provision of said predictions back to said information subsystem, d) a client interface subsystem which is a provider of displayed data to the destination sources, and e) an autonomous executive subsystem which is a start-up and control system for said intelligent server, an error recovery and message system, and a system health monitor.
Claim 3
Dependent Claim 35 words
The expert advisor system of claim 1 , wherein said input management subsystem further comprises one or more of a data sorter, a data identifier, a data corrector, and a data acquisition and search daemon.
Claim 4
Dependent Claim 57 words
The data acquisition and search daemon of claim 2 , wherein said data acquisition and search daemon is an independent program that is attached to a value or structure in the airport database, and said data acquisition and search daemon is a real-time daemon “invoked” or triggered automatically when said value or structure is read or changed.
Claim 5
Dependent Claim 21 words
The expert advisor system of claim 1 , wherein said input management subsystem is wholly or partially comprised of data agents.
Claim 6
Dependent Claim 42 words
The data agents of claim 4 , wherein said data agents are autonomous computer programs which manage data sources, initiate actions in response to events, and communicate and negotiate with other data agents within said expert advisor system without direct human control.
Claim 7
Dependent Claim 53 words
The expert advisor system of claim 1 , wherein said information subsystem is a data mining system, comprised of independent programs which run periodically to search all of said information subsystem for trends or discernable patterns to be routed for diagnostics, predictions and operations analysis to the appropriate said expert advisor system subsystems.
Claim 8
Dependent Claim 83 words
The data mining system of claim 6 , wherein said data mining consists of the application of commonly known knowledge-based reasoning and statistical computational techniques to find the “effective” or “valuable” information in the traffic data by: (a) constructing a model (or a set of models) for explaining the variation of the input data, (b) preprocessing (or transforming) the original data in order to make consistency between input data and the model, and, (c) identification of the model based on observed (input) data.
Claim 9
Dependent Claim 28 words
The input management subsystem of claim 1 , wherein historical data generated by said information subsystem or said prediction subsystem is routed back to said input management subsystem.
