Aircraft equipment control system
First Claim
1. An aircraft control system, comprising:
- a plurality of control panels that each comprise a plurality of control units which are configured to be operated by an operator;
a plurality of controllable pieces of equipment of the aircraft; and
a communication system for interconnecting the controllable equipment and associated control units, said communication system comprising a first and a second communication channel which are separate from each other and follow different paths in the aircraft, each of said first and second communication channels comprising, at least at the level of said control panels, at least two different digital communication buses; and
a plurality of first computers and a plurality of second computers, wherein;
each of said controllable pieces of equipment is controlled by at least one of said first computers and at least one of said second computers, in accordance with operation of at least one of said control units which is also associated with said control panels;
said first communication channel connects some of said control units to said first computer;
said second communication channel connects some of said control units to said second computer; and
at least one of said communication channels comprises;
two digital communication buses of a first type corresponding to a serial link permitting asynchronous multi-master operation, linked to said control panels;
a digital communication bus of a second type corresponding to a full duplex switched Ethernet network, which is linked to computers of the controllable pieces of equipment, these computers being associated with a communication channel; and
two gateways, linking said bus of said second type respectively to said buses of said first type, andeach of said control panels is connected to said digital communication buses of said communication channels.

Abstract
The control system (1) comprises at least one control panel (P1, Pn) comprising a plurality of operable control means (2) for controllable pieces of equipment (EC1, ECk) of the aircraft, each of which is controlled by first and second computers (3A1, 3Ak, 3B1, 3Bk), and a communication system (4) comprising a first and a second communication channel (5, 6) which are separate from each other and follow different paths (C1, C2), the first communication channel (5) connecting the control means (2) to the first computers (3A1, 3Ak) and the second communication channel (6) connecting the control means (2) to the second computers (3B1, 3Bk), each of said communication channels (5, 6) comprising two different digital communication buses (8, 9; 10, 11).
