Multiple aircraft engine control system and method of communicating data therein

摘要

The multiple aircraft engine control system having a corresponding engine controller associated with each one of the engines, each one of the engine controllers having at least two independent channels, each one of the at least two independent channels having at least two communication buses, each one of the at least two communicating buses of each channel being connected to a respective one of the at least two communicating buses of each one of the other channels. The method can time-interweave originating data of the channels.

1. A method of communicating data in an aircraft having at least two engines, the method comprising:
providing a first engine controller associated with a first channel of the first engine and a second engine controller associated with a second channel of the first engine, and a second engine comprising a third engine controller associated with a third channel of the second engine and a fourth engine controller associated with a fourth channel of the second engine; providing a first communication bus in a first multidrop arrangement between the first channel, the second channel, the third channel, and the fourth channel, and a second communication bus in a second multidrop arrangement between the first channel, the second channel, the third channel, and the fourth channel; and configuring at least one of the first engine controller, the second engine controller, the third engine controller, and the fourth engine controller for:
separating the data into at least a first portion and a second portion;time interweaving the first portion and the second portion of data between the first communication bus and the second communication bus; andbroadcasting the first portion and the second portion of data on the first communication bus and the second communication bus such that the first portion and the second portion of data are each broadcast twice, once on each of the first communication bus and the second communication bus in alternating order.
