Abstract

A method for identifying a machine and/or machine component includes storing an algorithm for generating a machine signature value associated with the machine and/or machine component. The method also includes receiving a first set of machine data from the machine and/or machine component. The machine data reflects at least one operational characteristic of the machine and/or machine component. The method also includes generating, using the algorithm, a first machine signature value based on the first set of machine data, storing the first machine signature value, and accessing the stored first machine signature value to verify the identity of the machine and/or machine component.

Claims

1. A method for identifying at least one of a machine and a machine component, comprising:

storing an algorithm for generating a machine signature value associated with the at least one of the machine and the machine component;

receiving a first set of machine data from the at least one of the machine and the machine component, the machine data reflecting at least one operational characteristic of the at least one of the machine and the machine component;

generating, using the algorithm, a first machine signature value based on the first set of machine data;

storing the first machine signature value;

accessing the stored first machine signature value to verify the identity of the at least one of the machine and the machine component;

receiving a second set of machine data from the at least one of the machine and the machine component;

generating, using the algorithm, a second machine signature value based on the second set of machine data;

comparing the first machine signature value to the second machine signature value; and

identifying the at least one of the machine and the machine component based on the comparison of the first and second machine signature values.

2. The method of claim 1, further including sending a message identifying the at least one of the machine and the machine component to an off-board system.

3. The method of claim 1, further including:

reading a third set of machine data from the at least one of the machine and the machine component using a portable device that connects to the machine;

using the algorithm to generate a third machine signature value based on the third set of machine data;

comparing the first machine signature value to the third machine signature value; and

identifying the at least one of the machine and the machine component based on the comparison of the first and third machine signature values.

4. The method of claim 3, wherein the portable device generates the third machine signature value and compares the first and third machine signature values.

5. The method of claim 1, further including:

receiving a reporting message from the at least one of the machine and the machine component, when the at least one of the machine and the machine component is in an abnormal condition; and

sending, based on the reporting message, a command message to the at least one of the machine and the machine component to command the at least one of the machine and the machine component to respond with a locating message, the locating message including location data relating to a geographical location of the at least one of the machine and the machine component.

6. The method of claim 5, wherein the abnormal condition includes at least one of an unscheduled staff and an unscheduled change in location of the at least one of the machine and the machine component.

7. The method of claim 5, wherein the locating message includes a second set of machine data, and the method further includes:

using the algorithm to generate a second machine signature value based on the second set of machine data;

comparing the first machine signature value to the second machine signature value; and

identifying the at least one of the machine and the machine component based on the comparison of the first and second machine signature values.

8. The method of claim 5, further including:

in response to the reporting message, analyzing a set of stored machine signature values, the set of stored machine signature values including the first machine signature value; and

flagging, based on the analysis, the first signature value to indicate that the at least one of the machine and the machine component is in the abnormal condition.

9. The method of claim 1, wherein the first set of machine data includes at least one of an identifier for the at least one of the machine and the machine component, historical operational information relating to the at least one of the machine and the machine component, scheduling information relating to an operation of the at least one of the machine and the machine component, and a fault code relating to the at least one of the machine and the machine component.

10. A method for identifying at least one of a machine and a machine component, comprising:

generating a first machine signature value associated with an operational characteristic of the at least one of the machine and the machine component at a first location;
