| 摘要 |
The invention relates to a fly-by-wire system which comprises: three-stage piloting control (4), each stage including a control computer (16, 18, 20) suitable for determining the positions of the stick, and a monitoring computer (22, 24, 26) capable of verifying all the pre-determined positions of the stick; three-stage control-surface position calculation (6), each stage including a control computer (40, 42, 44) suitable for calculating the control-surface positions from encoded positions of the stick, and a monitoring computer (46, 48, 50) capable of verifying all the calculated control-surface positions; a single unidirectional communication link (88) connecting the control computer (16) of the first piloting control stage to the control computer (40) of the first control-surface position calculation stage; a single unidirectional communication link (132) connecting the control computer (18) of the second piloting control stage to the control computer (42) of the second control-surface position calculation stage; and a single unidirectional communication link (142) connecting the control computer (20) of the third piloting control stage to the control computer (44) of the third control-surface position calculation stage. |
