Embodiment Construction

[0042] These figures are presented for illustrative purposes and in no way limit the invention. Identical elements that appear in different figures have a single reference numeral unless otherwise indicated.

[0043] figure 1 The first aspect of the present invention illustrated in relates to the impact detection device 3 .

[0044] The device 3 according to the first aspect of the invention comprises at least one impact detector DC. The impact detector DC may eg comprise an accelerometer or alternatively a piezoelectric sensor. In one embodiment, the device 3 comprises a plurality of impact detectors DC, the properties of the detector DCs of the plurality of detectors DCs may be the same or different. Therefore, a measurement redundancy system can be established to ensure its accuracy by selecting, for example, detectors of the same nature. Detectors of different properties can also be selected, each detector being able to be sensitive to a different signal.

Abstract

A first aspect of the invention relates to an impact detection device (3) comprising: an impact detector (DC), a wireless communication means (MC), an energy storage means (MS), an autonomous electrical energy generating means (GE) different from the impact detector (DC), a radio frequency energy receiving means (RF), the device (3) being configured to adopt the following two modes: a first mode, referred to as an autonomous mode, wherein the autonomous electrical energy generating device (GE) is configured to power the impact detector (DC) and the wireless communication device (MC); a second mode, referred to as an external mode, in which the radio frequency energy receiving device (RF) is configured to power the impact detector (DC) and the wireless communication device (MC).

Description

technical field [0001] The technical field of the invention is that of impact detection. [0002] The present invention relates to a crash detection device, and in particular to a crash detection device configured to operate according to different modes depending on conditions of use. The invention also relates to a detection system comprising a plurality of detection devices according to the invention and an aircraft equipped with such a system. Background technique [0003] In a known manner, aircraft comprise a fuselage made of composite material, usually comprising carbon fibres with a thermoplastic matrix, in order to benefit from a high mechanical strength of low mass compared to fuselages made of traditional metallic materials. When an aircraft is parked at an airport, vehicles (trailers, trucks, etc.) circulating within the airport can easily come into contact with the aircraft, which can damage its composite fuselage. Such damage reduces the mechanical strength of...
