Abstract

A remote diagnostics kit is provided to permit an in-flight entertainment system of an aircraft to be diagnosed remotely by an operator who is not on-site with the aircraft. The kit includes a remote computer, such as a laptop, that is connected to the IFE or a unit to be diagnosed. A technician operating a base computer accesses the remote computer over an appropriate communications network or series of networks. For example, in an embodiment, the remote computer includes a wireless modem, such as a cellular telephone modem, which the base computer accesses over the Internet. The base computer and remote computer are equipped with appropriate software to permit communication between the base and remote computers. Accordingly, through the base computer, the technician can command operation of a diagnostics program running at the remote computer, and output from the diagnostics program is transmitted to the base computer for display.

Claims

1. A remote access system for diagnosing at least one target component of an IFE on an aircraft, the system comprising:

an IFE interface onboard the aircraft, the IFE interface being in communication with the at least one target component;

a base computer, the base computer being equipped with a base program and first communication equipment for connecting the base computer to communicate over a communications network;

a remote computer located at an aircraft site, the remote computer being conveyable onboard the aircraft and removably connectable to the IFE interface, the remote computer being equipped with a diagnostic program operable to analyze the at least one target component of the IFE when the remote computer is connected to the IFE interface, and to generate output; and

second communication equipment for connecting the remote computer to communicate over the communications network with the base computer wherein the diagnostic program at the remote computer receives input from the base computer and wherein the remote computer transmits output to the base computer,

wherein the base program is configured to send at least one command to the diagnostic program at the remote computer and receive output from the diagnostic program at the remote computer in response to the at least one command, and

wherein, based on the command received from the base program, the remote computer queries the at least one target component of the IFE and sends a query response to the base computer.

2. The system of claim 1, wherein the second communication equipment for connecting the remote computer includes a wireless modem.

3. The system of claim 2, wherein the wireless modem is a cellular telephone modem.

4. A method for remotely accessing an in-flight entertainment (IFE) system for diagnosis, the method comprising the steps of:

providing a remote computer having a first communication interface for communicating with the IFE system, a second communication interface for communicating with a wide area network (WAN), and a communication server process for receiving a diagnostic request message via the second interface, querying at least one target unit of the IFE system responsive to the diagnostic request, receiving diagnostic information from the at least one target unit of the IFE system, and sending a response message to the diagnostic request that contains the diagnostic information;

providing a base computer having a communication interface for communicating with a wide area network and a maintenance application for interfacing with a user, the base computer being configured to receive a user input identifying desired diagnostic information, transmit a request message for the desired diagnostic information via the wide area network, receive a response message containing the desired diagnostic information, and display for the user the diagnostic information from the response message;

conveying the remote computer onboard the aircraft;

establishing a temporary physical connection between the first communication interface of the remote computer and an IFE interface onboard the aircraft, the IFE interface being in communication with the at least one target unit of the IFE system;

establishing a communication link from the remote computer to the base computer via the wide area network;

receiving a user request for desired diagnostic information for the at least one target unit of the IFE system at the base computer;

transmitting a request message for the desired diagnostic information from the base computer to the remote computer via the WAN;

receiving the request message for the desired diagnostic information in the remote computer and, responsive thereto, querying the at least one target unit of the IFE system for the desired diagnostic information;

receiving diagnostic information from the at least one target unit of the IFE system and, responsive thereto, sending a response message including the diagnostic information from the at least one target unit of the IFE system from the remote computer to the base computer via the WAN; and

receiving the response message including the diagnostic information from the at least one target unit in the base computer and, responsive thereto, displaying the diagnostic information from the at least one unit to the user.

5. The method of claim 4, wherein the second communication interface of the remote computer is a wireless communication interface.

6. The method of claim 5, wherein the wireless communication interface is selected from the group consisting of a mobile telephone interface, a radio interface, and a wireless network interface card.

7. The method of claim 4 further comprising the step of establishing through the temporary physical connection a communication link from the remote computer to the at least one target unit of the IFE system.

8. The method of claim 7 wherein the step of establishing through the temporary physical connection a communication link from the remote computer to the at least one target unit of the IFE system is performed before the step of establishing a communication link from the remote computer to the base computer via the wide area network.

9. The method of claim 7 wherein the step of establishing through the temporary physical connection a communication link from the remote computer to the at least one target unit of the IFE system is performed after the step of establishing a communication link from the remote computer to the base computer via the wide area network.

10. A remote diagnostic system for remotely accessing at least one target unit of an in-flight entertainment (IFE) system on an aircraft for diagnosis, the system comprising:

an IFE interface onboard the aircraft, the IFE interface being connected to an aircraft communication network linked with the at least one target unit;

a remote computer being conveyable onboard the aircraft and removably connectable to the IFE interface, the remote computer having a first communication interface for communicating with the IFE system, a second communication interface for communicating with a wide area network (WAN), and a communication server process for receiving a diagnostic request message via the second interface, querying the at least one target unit of the IFE system via the aircraft communication network in response to the diagnostic request, receiving diagnostic information from the at least one target unit of the IFE system via the aircraft communication network, and sending a response message to the diagnostic request that contains the diagnostic information; and

a base computer having a communication interface for communicating with a wide area network and a maintenance application for interfacing with a user, the base computer being capable of receiving a user input identifying desired diagnostic information, transmitting a request message for the desired diagnostic information via the wide area network, receiving a response message containing the desired diagnostic information, and displaying for the user the diagnostic information from the response message.

11. The system of claim 10, wherein the second communication interface of the remote computer is a wireless communication interface.

12. The system of claim 11, wherein the wireless communication interface is selected from the group consisting of a mobile telephone interface, a radio interface, and a wireless network interface card.
