Abstract

A universal event/data recorder system provides a common bridge between various event/data recorders found on mobile assets. The universal event/data recorder system includes an onboard segment that is capable of interfacing with any manufacturer'"'"'s event/data recorder device. Additionally, the universal event/data recorder system also includes a remote segment for accessing, analyzing and reviewing data collected from any of a plurality of event/data recorders. The universal event/data recorder system may allow accessing data from various event/data recorders using any of a number of communication means including the Internet and a wireless communication network.

Claims

1. A communication apparatus located on-board a mobile asset, the apparatus comprising:

a plurality of event/data recorders (EDRs), each EDR operating according to a predetermined communication protocol, certain of said communication protocols differing from other said communication protocols;

a memory adapted to store said predetermined communication protocols of each of the plurality of event/data recorders;

a processor adapted to dynamically determine the configuration of an event/data recorder of the plurality of event/data recorders, to select the communication protocol based on the configuration of the event/data recorder, and to configure an EDR interface to communicate with the event/data recorder using the selected communication protocol; and

the EDR interface adapted to communicate with the event/data recorder using the selected communication protocol.

2. The communication apparatus of claim 1, further comprising a transmitter adapted to transmit data from the event/data recorder to a remote computer.

3. The communication apparatus of claim 2, wherein the transmitter is a wireless transmitter adapted to transmit data to the remote computer in a wireless manner.

4. The communication apparatus of claim 1, further comprising a client interface adapted to communicate data from the event/data recorder to a remote computer and to communicate commands from the remote computer to the EDR interface.

5. The communication apparatus of claim 4, further adapted to:

receive a request from the remote computer at the client interface to communicate with the event/data recorder using a first communication protocol;

interrupt communication between the EDR interface and the event/data recorder;

reconfigure the EDR interface and the client interface to operate in a pass-through mode; and

operate the client interface and the EDR interface in the pass-through mode.

6. The communication apparatus of claim 5, further adapted to:

monitor the client interface for any communication from the remote computer; and

discontinue operating the client interface and the EDR interface in the pass-through mode if the remote computer is not active at the client interface.

7. The communication apparatus of claim 6, wherein the client interface is a wireless interface and the remote computer is a wireless transceiver.

8. The communication apparatus of claim 1, wherein the memory includes communication protocols used to communicate using at least one of:

(1) RS232 protocol;

(2) Ethernet protocol;

(3) RS485 protocol;

(4) RS422 protocol;

(5) controller area network (CAN) protocol; and

(6) universal serial bus (USB) protocol.

9. The communication apparatus of claim 1, further adapted to synchronize the time of the communication apparatus to universal time and to communicate the synchronized time to each of the plurality of EDRs.

10. The communication apparatus of claim 1, further adapted to:

synchronize the time of the communication apparatus to universal time;

request local EDR times from each of the plurality of EDRs;

compare local EDR times with the synchronized time; and

send a command to one or more of the plurality of EDRs to adjust their local EDR times to the synchronized time.

11. The communication apparatus of claim 1, wherein the memory is further adapted to store a data processing program to process event data received from the plurality of EDR(s), the data processing program comprising:

a first routine to receive data from the EDR in a format generated by the EDR;

a second routine to convert the data received from the EDR into a format presentable via an Internet browser; and

a third routine to communicate the converted data using the client interface.

12. The communication apparatus of claim 11, wherein the memory is further adapted to store format specifications for data generated by a plurality of EDRs and wherein the second routine uses the format specifications to convert the data received from the EDR.

13. A method of communicating with an event/data recorder (EDR), the method comprising:

determining the configuration of the EDR;

selecting a communication protocol based on the configuration of the EDR;

configuring an EDR interface to communicate with the EDR using the selected communication protocol; and

communicating with the EDR via the EDR interface.

14. The method of claim 13, wherein the EDR is one of a plurality of EDRs, each of the plurality of EDRs communicating using a different communication protocol.

15. The method of claim 13 further comprising:

receiving EDR data from the EDR;

selecting an EDR data format based on the configuration of the EDR;

interpreting the EDR data based on the EDR data format; and

storing the EDR data on a memory of an onboard hardware platform.

16. The method of claim 15, further comprising:

converting the EDR data into a format readable by an Internet browser software; and

communicating the converted EDR data to a remote computer.

17. The method of claim 16, wherein communicating the converted data to a remote computer comprises wirelessly communicating the converted data to a remote computer.

18. The method of claim 17, further comprising:

synchronizing time of the onboard hardware platform with universal time;

receiving the local time on the EDR;

comparing the EDR time with the universal time; and

if the EDR time is different than the universal time, sending a request to the EDR to update its local time.

19. A method of communicating data from an EDR to a remote client using an onboard platform system having an EDR interface communicatively connected to the EDR and a remote client interface communicatively connected to the remote client, the method comprising:

receiving at the remote client interface a request from the remote client for data from the EDR;

dynamically determining the configuration of the EDR and the configuration of the remote client;

selecting a communication protocol based on the configuration of the EDR and the configuration of the remote client;

interrupting any existing communication with the EDR at the EDR interface;

reconfiguring the EDR interface to communicate with the EDR using the selected communication protocol;

reconfiguring the EDR interface and the remote client interface to communicate with each other in a pass-through mode; and

communicating data from the EDR to the remote client using the EDR interface and the remote client interface communicating in the pass-through mode.

20. The method of claim 19, wherein the remote client communicates with the remote client interface in a wireless manner.

21. The method of claim 19 further comprising providing time adjustment to the EDR to adjust the EDR time to universal time.
