Version control for software configurable aircraft systems

摘要

A software version control system and method includes installing a software configurable component on an aircraft, automatically setting a listen switch of the software configurable component to an on state upon installation of the software configurable component in a new installation location, listening for a software version from a configuration manager on a communication bus, turning off the listen switch if a software version of the software configurable component matches the software version of the configuration manager, and downloading an updated software version to the software configurable component if the software version of the software configurable component does not match the software version of the configuration manager.

1. A software version control method comprising:
installing a software configurable component on an aircraft; automatically setting a listen switch of the software configurable component to an on state upon installation of the software configurable component in a new installation location, wherein the software configurable component does not command power outputs to a configuration manager on a power path while the listen switch is in the on state and wherein automatically setting the listen switch of the software configurable component to an on state comprises:
reading a radio frequency identification (RFID) tag associated with the installation location to obtain a location tag value;comparing a previously read tag value with the location tag value; andsetting the listen switch to the on state if the previously read tag value does not match the location tag value; manually setting the listen switch to an on state if no previous tag value has been read by the software configurable component; listening for a software version from the configuration manager on a communication bus; turning off the listen switch if a software version of the software configurable component matches the software version of the configuration manager; and downloading an updated software version to the software configurable component if the software version of the software configurable component does not match the software version of the configuration manager.
