Abstract

A tray for an avionics bay, comprising a body and a recording device rigidly connected to each other in order to reduce the space requirement of acquisition systems on board an aircraft and dedicated to the prediction of failures. The recording device comprises a first input/output port to be connected to the avionics bay, a second input/output port to be connected to an item of electrical equipment, a data bus for routing signals between the first and the second input/output port, a collection member configured for acquiring at least some of the signals routed by the data bus between the first and the second input/output port, and a memory configured to store the signals acquired by the collection member.

Claims

1. A tray configured to be mounted in an avionics bay of an aircraft, the tray comprising

a body configured to support electrical equipment received into the avionics bay, and

a recording device comprising:

a first input/output port configured to be connected to a connector of the avionics bay;

a second input/output port configured to be connected to a connector of the electrical equipment;

a data bus connected between the first input/output port and the second input/output port and configured to rout signals between the first input/output port and the second input/output port;

a collection member configured to acquire at least some of the signals routed by the data bus between the first input/output port and the second input/output port; and

a memory configured to store the signals acquired by the collection member,

wherein the recording device is rigidly connected to the body.

2. The tray according to claim 1, wherein the recording device further comprises a wireless communication module configured to transmit in at least one predetermined frequency band, all or part of the acquired signals stored in the memory.

3. The tray according to claim 2, wherein the wireless communication module is configured to apply a compression method to all or part of the acquired signals stored in the memory before their transmission.

4. The tray according to claim 1, wherein the first input/output port and the second input/output port are connectors compliant with a current international aeronautics standard for electrical connectors.

5. An avionics bay of an aircraft provided with at least one tray according to claim 1.

6. An aircraft provided with an avionics bay according to claim 5.
