Nautical device diagnosis apparatus, remote nautical device surveillance system, nautical device diagnosis method, and nautical device diagnosis computer-readable media

A method comprising:

• receiving at least one message from the at least one nautical one nautical electronic device, including identification data for identifying the at least one nautical electronic device and alarm state data indicating a current alarm state of the at least one nautical electronic device;
• comparing the current alarm state of the at least one nautical electronic device with a previous alarm state of the at least one nautical electronic device to detect a failure of the at least one nautical electronic device;
• transmitting failure detection information to a remote diagnostic center, the failure detection information comprising information associated with the failure of the at least one nautical electronic device and the identification data of the at least one nautical electronic device;
• receiving, from the remote diagnostic center, troubleshooting instructions to troubleshoot the failure of the at least one nautical electronic device;
• and
• comparing a message type of the at least one message with a target message type, wherein
• when the message type of the at least one message matches with the target message type, the at least one message is parsed;
• and
• when the message type of the at least one message does not match with the target message type, the at least one message is ignored.

A diagnostic apparatus for diagnosing at least one nautical electronic device on a vessel, the diagnostic apparatus comprising:

• a memory configured to store instructions;
• and
• processing circuitry configured to execute the stored instructions to:
• receive at least one message from the at least one nautical electronic device,
• the at least one message including identification data for identifying the at least one nautical electronic device and alarm state data indicating a current alarm state of the at least one nautical electronic device;
• compare the current alarm state of the at least one nautical electronic device with a previous alarm state of the at least one nautical electronic device to detect a failure of the at least one nautical electronic device;
• transmit failure detection information to a remote diagnostic center, the failure detection information comprising information associated with the failure of the at least one nautical electronic device and the identification data of the at least one nautical electronic device, and
• execute a second trigger process at scheduled intervals to:
• compare, at each scheduled interval, the current alarm state of the at least one nautical electronic device with the previous alarm state of the at least one nautical electronic device using the alarm state data in the at least one message, and
• transmit the failure detection information associated with the at least one nautical electronic device to the remote diagnostic center based on the processing of the at least one message by the second trigger process.
