Abstract

A Virtual Electrical and Electronic Device Interface and Management System (VEEDIMS) support architecture is provided. In one example, the VEEDIMS support architecture includes a vehicle layer and a shop layer. The vehicle layer has a module and a controller positioned in a vehicle. The module is configured to couple to a device via an input/output (I/O) interface compatible with the device and configured to couple to the controller via a cable adapted to simultaneously carry bi-directional data and uni-directional power to the module. The shop layer is separate from the vehicle layer and has a browser configured to communicate with an HTTP server in the module and an analysis tool configured to receive and analyze event driven and time series data from the controller.

Claims

1. A Virtual Electrical and Electronic Device Interface and Management System (VEEDIMS) support architecture comprising:

a vehicle layer having;

a module positioned in a vehicle and configured to couple to a device via an input/output (I/O) interface compatible with the device and configured to couple to a controller via a cable adapted to simultaneously carry bi-directional data and uni-directional power to the module, wherein the module has a first processor and a first memory containing a first instruction set executable by the first processor, the first instruction set including instructions for providing a HyperText Transfer Protocol (HTTP) server, and wherein the first memory further contains a documentation set containing a service history of the module and a bill of materials for at least one of the module and the device that is accessible via the HTTP server and both event driven and time series data captured from the device and the module during operation of the vehicle; and

the controller positioned in the vehicle and having a second processor and a second memory containing a second instruction set executable by the second processor, the second instruction set including instructions for receiving data from the module and storing the data in the second memory, wherein the data includes the event driven and time series data; and

a shop layer separate from the vehicle layer having;

a browser configured to communicate with the HTTP server to access the documentation set; and

an analysis tool configured to receive the event driven and time series data from the controller and analyze a performance of the vehicle compared to predefined optimal vehicle parameters using the event driven and time series data.

2. The VEEDIMS support architecture of claim 1 wherein the first instruction set further comprises instructions for a diagnostics component configured to obtain diagnostics data about the module and the device and to transfer the diagnostics data via at least one of the HTTP server and the cable.

3. The VEEDIMS support architecture of claim 1 wherein the first instruction set further comprises instructions for a configuration component configured to set operational parameters for at least one of the module and the device.

4. The VEEDIMS support architecture of claim 1 wherein the first instruction set further comprises instructions for a data acquisition component configured to acquire data about at least one of the module and the device.

5. The VEEDIMS support architecture of claim 4 wherein the data acquisition component includes an Embedded Component Historian Object (ECHO) coupled to an ECHO driver for sending the acquired data from the module to the controller via the cable.

6. The VEEDIMS support architecture of claim 1 wherein the first instruction set further comprises instructions for monitoring the device to create a device profile and sending the device profile to the controller.

7. A Virtual Electrical and Electronic Device Interface and Management System (VEEDIMS) support architecture comprising:

a vehicle layer having;

a plurality of modules positioned in a vehicle, wherein each module is configured to couple to at least one device via an input/output (I/O) interface compatible with the device and configured to couple to a controller via a cable adapted to simultaneously carry bi-directional data and uni-directional power to the module, and wherein each module has a first processor and a first memory containing a first instruction set executable by the first processor, the first instruction set including instructions for capturing and storing both event driven and time series data from the module and the device during operation of the vehicle; and

the controller positioned in the vehicle and having a second processor and a second memory containing a second instruction set executable by the second processor, the second instruction set including instructions for receiving data from each of the plurality of modules and storing the data in the second memory, wherein the data includes the event driven and time series data; and

a shop layer separate from the vehicle layer and having;

a communications component configured to obtain the data from at least one of the plurality of modules and the controller;

a server configured to store the obtained data; and

an analysis tool configured to review and analyze the event driven and time series data to correlate the event driven and time series data to a specific fault event and to view a status of vehicle layer systems during the interval of the specific fault event.

8. The VEEDIMS support architecture of claim 7 wherein the analysis tool is further configured to analyze the event driven and time series data from a point before a failure occurs to develop a picture of events that led to the failure.

9. The VEEDIMS support architecture of claim 7 wherein the event driven and time series data is filtered only for compression and exceptions to increase storage efficiency without losing resolution.

10. The VEEDIMS support architecture of claim 7 wherein the event driven and time series data is stored using a batch sub-system that stores pointers to a beginning and an end of specific parts of the event driven and time series data to allow for comparisons between similar events using overlay.

11. The VEEDIMS support architecture of claim 10 wherein the similar events include all engine start events, wherein the batch sub-system organizes the engine start events so the engine start events can be recalled and compared to develop a model of an optimal engine start.

12. The VEEDIMS support architecture of claim 11 wherein the engine start events are recalled and compared to predict a need for maintenance as parameters drift from the model of the optimal engine start.

13. The VEEDIMS support architecture of claim 7 wherein the analysis tool is further configured to execute a plurality of preventive maintenance functions by observing trends that move away from normal operational parameters based on the event driven and time series data.

14. The VEEDIMS support architecture of claim 7 wherein the analysis tool is further configured to identify fault conditions used to define predictive means for preventing future component failures based on the event driven and time series data.

15. The VEEDIMS support architecture of claim 7 wherein at least one of the first and second memories supports serial data storage of the event driven and time series data to enable time and excursion based fault analysis after a failure occurs.

16. The VEEDIMS support architecture of claim 7 wherein the shop layer further includes a configuration component configured to set parameters for at least one of the controller, the plurality of modules, and the devices coupled to the plurality of modules.

17. The VEEDIMS support architecture of claim 16 wherein the configuration component uses Extensible Markup Language (XML) configuration information.

18. The VEEDIMS support architecture of claim 7 further comprising an enterprise layer for fleet management having:

a communications component configured to obtain the data from the server in the shop layer;

a database configured to store at least a portion of the data from the server; and

a second analysis tool configured to retrieve the event driven and time series data from the data stored in the database for analysis.

19. The VEEDIMS support architecture of claim 7 wherein each of the plurality of modules includes a HyperText Transfer Protocol (HTTP) server, and wherein the first memory of each of the plurality of modules contains a documentation set containing a service history of the module and a bill of materials for at least one of the module and the device that is accessible via the HTTP server.

20. The VEEDIMS support architecture of claim 19 wherein the shop layer further includes a browser configured to communicate with the HTTP server to access the documentation set.
