Abstract

A system for collecting and communicating data associated with at least one of a plurality of machines includes a sensor. The sensor is configured to monitor an operational condition of the at least one associated machine and provide signals indicative of the operational condition. The system includes at least one local data system, including a processor, associated with the machine and configured to receive signals from the sensor, detect an event affecting the at least one machine based on the signals received from the sensor, and communicate data relevant to the detected event to a location remote from the at least one machine. A central data system including a processor and configured to receive the data relevant to the detected event and communicate with other machines of the plurality of much such that the other machines communicate data relevant to the detected event to the central data system is included.

Claims

1. A system for collecting and communicating data associated with at least one of a plurality of machines, the system comprising:

at least one sensor associated with at least one of the plurality of machines, the at least one sensor being configured to monitor an operational condition of the at least one machine and provide signals indicative of the operational condition;

at least one local data system associated with the at least one machine, the at least one local data system including a processor and being configured to;

receive signals from the at least one sensor;

detect an event affecting the at least one machine based on the signals received from the at least one sensor; and

communicate data relevant to the detected event to a location remote from the at least one machine; and

a central data system including a processor and configured to receive the data relevant to the detected event, and communicate with other machines of the plurality of machines such that the other machines communicate data relevant to the detected event to the central data system,

wherein the central data system is further configured to;

identify a plurality of machines that share a characteristic with the at least one machine;

communicate the identity of the relevant data to the local data systems associated with the plurality of machines; and

receive the relevant data from each of the local data systems associated with the plurality of machines.

2. The system of claim 1, wherein the at least one local data system is further configured to:

collect event-specific data based on the event; and

transmit the event-specific data to the central data system.

3. The system of claim 2, wherein the central data system is further configured to:

receive a first signal from the at least one local data system indicative of the event; and

send a second signal to the at least one local data system identifying the relevant data and the event-specific data and requesting the at least one local data system collect the event-specific data.

4. The system of claim 2, wherein the at least one local data system is further configured to:

determine whether a second event occurred on a second machine;

collect event-specific data based on the second event; and

transmit the event-specific data to the central data system.

5. The system of claim 4, wherein the at least one local data system is further configured to receive an event trigger signal from the central data system indicative of the second event that occurred on the second machine.

6. The system of claim 1, wherein the central data system is further configured to:

command each of the local data systems associated with the plurality of machines to collect event-specific data; and

receive the event-specific data and the relevant data from each of the plurality of machines.

7. The system of claim 1, wherein the shared characteristic includes at least one of a machine type, a machine model, a working condition, a geographic location, and an environmental condition.

8. A machine fleet comprising:

a plurality of machines; and

a data collection system including;

at least one sensor associated with at least one of the plurality of machines, the at least one sensor being configured to monitor an operational condition of the at least one machine and provide signals indicative of the operational condition;

at least one local data system associated with the at least one machine, the at least one local data system including a processor and being configured to;

receive signals from the at least one sensor;

detect an event affecting the at least one machine based on the signals received from the at least one sensor; and

communicate data relevant to the detected event to a location remote from the at least one machine; and

a central data system including a processor and configured to receive the data relevant to the detected event, and communicate with other machines of the plurality of machines such that the other machines communicate data relevant to the detected event to the central data system,

wherein the central data system is further configured to;

identify a subset of the plurality of machines that shares a characteristic with the affected machine;

communicate an identity of the relevant data to a local data system associated with each machine of the subset; and

receive relevant data from each of the local data systems associated with the subset.

9. The machine fleet of claim 8, wherein the central data system is further configured to:

receive a first signal from the at least one local data system indicative of the event; and

send a second signal to the at least one local data system identifying the relevant data portion and event-specific data to be collected, and requesting the at least one local data system to collect the event-specific data.

10. The machine fleet of claim 8, wherein a plurality of local data systems are associated with the plurality of machines and each of the plurality of local data systems is further configured to:

collect event-specific data based on the event; and

transmit the event-specific data to the central data system.

11. The machine fleet of claim 8, wherein the central data system is further configured to:

command each of the local data systems associated with the subset to collect event-specific data; and

receive the event-specific data and the relevant data from each local data system of the subset.

12. The machine fleet of claim 8, wherein the shared characteristic includes at least one of a machine type, a consist, a load type, an environmental condition, a machine model, and a geographic location.
