Abstract

In one embodiment, a server electrically connected to an image processing machine provides local data access and includes a monitor component, an analysis and prediction component to analyze data to track machine trends and predict machine subsytem and element faults, a diagnostic component capable of machine diagnostics at a higher level, components, and a communication component to provide a remote communication link. In a second embodiment, a first level of server modules are directly connected to given machines, a second level of server modules with trend analysis and diagnostic capability are connected to a network and associated with a set of machines on the network, and a third level of server modules are associated with a plurality of sets of machines on the network with the analysis and prediction components and diagnostic components providing trend data, fault prediction data, and machine corrective data for the plurality of sets of machines.

Claims

1. A first server electrically connected to an image processing machine, the image processing machine including a control with a first level data collection element, sensors for providing first level data to the data collector element, and a first level diagnostic element, the server providing local access, the first server comprising:

a monitor component connected to the control for receiving the first level data and for receiving a second level of data generated by said sensors,

an analysis and prediction component connected to the monitor component to analyze the first and second level data to track machine trends and predict machine subsytem and element faults,

a diagnostic component capable of machine diagnostics at a second level, the diagnostic component connected to the monitor and analysis and prediction components, and

a communication component connected to the monitor, diagnostic, and analysis and prediction components to provide a remote communication link, the first server being adopted to connect to a network server over the communication link.

2. The first server of claim 1, including memory for storing said second level of data and data related to machine analysis and predicted events.

3. The first server of claim 1 wherein the monitor receives data independent of the data collection element including data for changing machine behavior.

4. The first server of claim 1 wherein the first server is portable.

5. The first server of claim 1 wherein the communication component prepares trend data, fault prediction data, and machine corrective data for local access.

6. The first server of claim 1 wherein the communication component prepares trend data, fault prediction data, and machine corrective data for remote transmission.

7. In an image processing machine having an associated server module, sensors, and a control with a first level diagnostic element for diagnosing a first level of data generated by the machine sensors, a method of diagnosing machine operation comprising the steps of:

receiving in the server module first level diagnostic data and a second level of data generated by the machine sensors,

responding to the analysis of the first level diagnostic data and data generated by the machine sensors to provide a second level of diagnostics data, and providing a network communication link in the server module to provide said predicted machine event and fault data and said second level of diagnostic data to a remote location, and

providing a local communication link in the server module to access said predicted machine event and fault data and said second level of diagnostics data.

8. The method of claim 7 including the steps of storing in a memory in the server module said second level of diagnostic data and date related to machine analysis and predicted events.

9. The method of claim 7 including the step of providing a remote communication link in the server module to access said predicted machine event and fault data and said second level of diagnostics data.

10. The method of claim 7 including the step of directly connecting the server module to the image processing machine.

11. The method of claim 10 including the step of disconnecting the server module from the image processing machine.

12. In an image processing machine having sensors and a control with a first level diagnostic element receiving a first level sensor data and a server module, the server module electrically connected to the control, a method of diagnosing machine operation comprising the steps of:

receiving in the server module first level diagnostic data and second level sensor data generated by the machine sensors,

analyzing the first level diagnostic data and the second level sensor data generated by the machine sensors to track machine trends and provide predicted machine event and fault data, and

responding to the analysis of the first level diagnostic data and the second level sensor data generated by the machine sensors to provide a second level of diagnostic data.

13. The method of claim 12 including the step of providing a local communication link in the server module to access said predicted machine event and fault data and said second level of diagnostics data.

14. The method of claim 12 including the steps of storing in a memory in the server module said second level of diagnostic data and data related to machine analysis and predicted events.
