本发明涉及用于操作飞行器的操纵面(2)的飞行控制系统(1),其包括:用于飞行器的操纵面(2)冗余致动的多个执行器(3);用于接收、计算和转发控制信号的执行器‑控制电子装置(4),所述控制信号用于通过多个执行器(3)操作的操纵面(2);设置成用于分别控制和监控对应的执行器(3)的多个远程电子单元;以及用于在执行器‑控制电子装置(4)和多个远程电子单元(5)之间传送数据的第一数据总线系统(10),其中第一数据总数系统(10)包括:用于在执行器‑控制电子装置(4)和多个远程电子单元(5)的第一个单元之间传送数据的第一数据总线(11);用于在执行器‑控制电子装置(4)和多个远程电子单元(5)的第二个单元之间传送数据的第二数据总线(12),其中第一数据总线(11)和第二数据总线(12)基于相同的总线技术,其中第一数据总线系统(10)另外包括用于在执行器‑控制电子装置(4)和第一远程电子单元(5)之间传送数据的备份‑数据总线(13),其中该备份数据总线(13)的总线技术与第一数据总线成(11)和第二数据总线(12)不同。因为借助于主总线的双工构架提供高的系统可用性和设备可用性,备份‑数据总线被限制成仅在计算机之间进行数据交换,所述计算机仅被要求作为用于安全飞行操作的最小配置。未要求用于最小配置(最小控制)的系统组件和相关的电子设备也没有集成到备份网络。由此减小了复杂性、缆线铺设费用、缆线重量和安装成本。
The invention relates to a flight control system (1) for actuating a control surface (2) of an aircraft, comprising: a plurality of actuators (3) for the redundant actuation of a control surface (2) of the aircraft; actuator control electronics (4) for receiving, calculating and forwarding control signals for the control surface (2) to be actuated by means of the plurality of actuators (3); a plurality of remote electronic units (5), each provided for controlling and monitoring a corresponding actuator (3); and a first data bus system (10) for transferring data between the actuator control electronics (4) and the plurality of remote electronic units (5), the first data bus system (10) comprising a first data bus (11) for transferring data between the actuator control electronics (4) and a first of the plurality of remote electronic units (5) and comprising a second data bus (12) for transferring data between the actuator control electronics (4) and a second of the plurality of the remote electronic units (5), the first data bus (11) and the second data bus (12) being based on the same bus technology, the first data bus system (10) also comprising a backup data bus (13) for transferring data between the actuator control electronics (4) and the first remote electronic unit (5), and the backup data bus (13) being different in the bus technology thereof from the first data bus (11) and the second data bus (12). Because of the high system availability and device availability which are provided by means of the duplex architecture of the main bus, the backup data bus is limited only to data exchange between the computers which exclusively are required as a minimum configuration for safe flight operation. System components and associated electronic devices not required for the minimum configuration (minimum control) are also not integrated into the backup network. This leads to a reduction in the complexity, the cabling expense, the cable weight, and the installation costs.
