背景技术Background technique
在现代典型的飞机中，电力通过配电系统覆盖了飞机上各个设备或负载，这种广泛覆盖的馈线网络推动了技术人员想利用该馈线网络进行数据通信，即通过电力线通信(Power Line Communication，PLC)技术来实现这种想法和需求，这样飞机上的各个设备或负载之间就不需要依赖会导致额外重量和成本的专用通信数据网络。In a typical modern aircraft, electricity covers each device or load on the aircraft through the power distribution system. This extensive coverage of the feeder network drives technicians to use the feeder network for data communication, that is, through power line communication (Power Line Communication, PLC) technology to achieve this idea and need, so that there is no need to rely on a dedicated communication data network between the various equipment or loads on the aircraft that would cause additional weight and cost.
然而，飞机的这种馈线并非为数据通信而设计的，这让技术人员利用该馈线网络用于数据通信时，往往会侧重于提供通用性的电力线通信方案或把馈线网络看作是一个复杂整体处理，从而使其在电力线通信过程中，PLC信号在馈线上到处输送，未能考虑到飞机互联性的特定通信需求问题和未能考虑到通信传输中的不确定性问题，例如：不确定性的信号衰减、不确定性的馈线网络中其他各种信号源的噪声引入等。However, such feeders in aircraft are not designed for data communication, which makes technicians using the feeder network for data communication often focus on providing a general power line communication scheme or view the feeder network as a complex whole Processing so that during power line communication, PLC signals are transmitted everywhere on the feeder, failing to take into account the specific communication needs of aircraft interconnectivity and failure to consider uncertainties in communication transmission, such as: Uncertainty The signal attenuation of the uncertainty, the noise introduction of other various signal sources in the feeder network of uncertainty, etc.
