'further information. The use of such self-test functions makes it possible to ensure a certain level of safety by prohibiting the use of equipment which presents a malfunction, without generally allowing an operator of the system using the equipment to know the reasons for the problem. malfunction detected, and without storing associated details. Therefore, this type of method does not improve the performance of an equipment or the control of the system that uses the equipment.

It is also known practice to perform predictive maintenance for equipment of the aforementioned type.

The invention applies more generally to other types of electronic equipment, not comprising a radioelectric signal transmitter / receiver.

In addition, the equipment 6 comprises a communication interface 10 with a plurality of sensors 12a, 12b, 12c, 12d, 12e which are also part of the system 2 and are suitable for transmitting information to the equipment 6 via the interface. 10.

For example, the communication interface 10 is a wired connection interface. As a variant, it is a wireless communication interface. Finally, this interface can be plural, some sensors being connected wirelessly, others wired according to their capabilities.

In one embodiment, the sensor 12a is a geolocation sensor implementing a GNSS (“Global Navigation Satellite System”) satellite geolocation system, suitable for estimating, at regular time intervals, a geolocation information item in a given spatial reference frame. Geolocation information

Of course, Figure 1 is an example, a higher or lower number of sensors can be used.

In an alternative embodiment, the sensors are integrated into the equipment 6. Typically, a simple spectrum analysis function can be performed by the reception function of the radio equipment (when not in use by the radio equipment). elsewhere, or sometimes in addition thanks to parallel processing).

In addition to the sensors 12a to 12e, the device 6 is able to auto-capture internal operating information (eg: atypical heights, propagation conditions, etc.) from the functional module 8 or calculation unit 14 or label circulating on the internal buses

The equipment 6 further comprises a calculation processor 14, a memory unit 16, a communication unit 18 as well as a cryptographic module 17 to secure the information stored in the memory and its transmission.

As a variant, these units are produced in the form of programmable logic components, such as an FPGA (standing for Field-Programmable Gâte Arraÿ), or else in the form of dedicated integrated circuits, of the ASIC type (standing for AppUcation- Specific Integrated Circuit).

The communication unit is adapted to communicate, according to a suitable communication protocol, with the calculation system 4.

In one embodiment, the communication unit 18 is a wireless communication unit.

As a variant, the communication unit 18 is a wired communication unit, for example making it possible to implement an Ethernet connection.

The communication link produced by the communication unit 18 is for example encrypted to achieve secure communication.

The memory unit 16 is suitable for memorizing in particular an operation / malfunction log 21, comprising in particular a malfunction or failure report, enriched with information transmitted by the sensors 12a to 12e, as well as a mapping 20 of operating levels. as a function of at least one parameter representative of a condition of use of the equipment.

The cartography 20 is the main element allowing the increased operation of the equipment. It is built using feedback from the operational operation of the equipment and then, preferably, loaded (and updated) in all the equipment of the same family.

The generation and use of such a map 20 will be detailed below.

The memory unit 16 also stores several sets 22 of adjustment parameters to control the operation of the functional module 8.

The equipment 6 is also suitable for communicating, for example using a wired connection 23, with an on-board computer 24, which is schematically represented in FIG. 1.

Such an on-board computer comprises in particular a man-machine interface 26, making it possible to communicate with an operator, in particular to allow him to control the functionalities implemented by the on-board equipment (s) 6 as well as to configure the associated sensors 12a to 12e.

The on-board computer comprises an electronic computer 28 and a communication unit 30, adapted to communicate with the computing system 4.

In one embodiment, it is the on-board computer which centralizes and manages all the communications with the computing system 4, via the communication unit 30. In this case, the equipment 6 transmits all the information to be communicated, in particular the operation / malfunction log 21, for example via a secure communication link, to the on-board computer 24.

The calculation system 4 also comprises a communication unit 44, adapted to implement the communication protocol used respectively by the units 18 or 30.

FIG. 2 is a flowchart of a method of collecting operating data used for the generation of a mapping of operating levels, in one embodiment.

As explained in detail below, steps 50 to 58 are implemented by electronic equipment 6, and step 60 is implemented by a calculation system 4.

This method is implemented during a prior phase of testing the equipment, but can also be implemented during a phase of operational use of the equipment, making it possible to enrich the mapping of operating levels. .

The method comprises a first step 50 of acquiring data relating to the operation of the equipment 6. These data include on the one hand time-stamped data relating to the operation of the module 8 of the equipment 6, including breakdowns or failures, provided. for example by the self-test system of the equipment 6, and on the other hand, data received from the sensors 12a to 12e. The operating data are, for example, altitude measurements in the case of a radio altimeter, taken at regular time intervals, or even throughputs or ranges obtained in the case of radio-communications equipment, or also local interference levels or types of propagation channels encountered.

In one embodiment, the sensor data comprises at least one location information item, for example geographical and / or temporal.

The data collected is grouped together in step 52 in an operation / malfunction log of the equipment 6. Any malfunctions or failures are recorded, for example the results of the self-test system implemented by the equipment. The operation / malfunction log also includes temporal information, for example the date and time associated with each operating data item, as well as data from the sensors 12a to 12e which can be correlated with the operating data.

Then, at step 54 it is checked whether the communication resources are available for the transmission of operating data. Indeed, it is possible that the communication resources are used for higher priority tasks, for example tasks relating to piloting when the method is implemented on board an aircraft.

In the event of a negative response to the verification step 54, this step is followed by a step 56 of memorizing the operation / malfunction log for subsequent use.

In the event of a positive response to step 54, this is followed by a step 58 of transmitting the operating log (s) containing the data collected by the equipment 6 to a computing system 4.

According to one embodiment, the transmission is carried out by radio communication, using suitable communication units.

Alternatively, the transmission is made by a wired connection. In this case, the transmission is made subsequent to the acquisition of the data, the equipment being in this case directly connected by a wired link to the computing system 4.

The computing system receives the operation / malfunction log (s), and stores them in step 60.

Steps 50 to 60 are repeated throughout the operation of the equipment

6.

The calculation system 4 is suitable for receiving data collected by the same equipment item over several time periods, as well as data collected by several equipment items of the same equipment family.

A family of equipment refers to a set of equipment having the same technical specifications and comprising similar components, for example equipment from the same range supplied by a manufacturer.

FIG. 3 is a flowchart of a method for analyzing data relating to the operation of the equipment items collected in order to generate a map of operating levels, in one embodiment.

The steps of this method are implemented by a calculation system 4, having extended calculation capacities, including if necessary for the processing of big data.

Indeed, the memory units 42 of a calculation system 4 store very large amounts of data collected, from the same equipment 6 or from a plurality of equipment from the same family of equipment.

The data analysis method optionally comprises a step 70 for receiving and storing additional data.

The additional data includes, in one embodiment, environmental data, for example localized meteorological data. Thus, it is possible to correlate the operating data considered with meteorological conditions, knowing the date, time and spatial location information associated with the stored operating data.

The additional environmental data include, for example, geographic data, such as relief data. Finally, it may be radio propagation data obtained by calculation or external measurements.

These meteorological and geographical data are for example useful for characterizing the operation of a radio altimeter. The propagation data are for example useful for characterizing the operation of a transmitter / receiver.

Indeed, a radio altimeter can exhibit significant measurement variations when the relief is very steep or in the presence of fairly reflective elements (near certain airports for example). Compared to a surface without overground, a radio altimeter can exhibit measurement inaccuracy when weather conditions are very unfavorable (antenna performance being degraded).

Thus, an item of equipment may present a local malfunction due to environmental conditions without exhibiting a failure of one of its components. Similarly, in the case of radio communication, the presence of an obstacle, a very good reflector or even that of a jammer can lead to a local malfunction without this corresponding to the failure of the equipment. or one of its components.

The benefit of mapping operating states is that it makes it possible to identify the passage through known areas of ambiguity between a malfunction linked to the environment or a malfunction linked to the equipment.

Additional data may also include technical documentation, industrial data on the reliability of equipment components.

Step 70 is followed by a step 72 of processing and analyzing the stored data, comprising the collected data and, where appropriate, the additional data, in order to construct a map of the operating state of the equipment.

L’analyse de données est effectuée en utilisant des algorithmes d’analyse de données massive (en anglais « data analytics »). Par exemple, pour construire une cartographie de niveaux de fonctionnement, tous les moments de dysfonctionnement sont placés sur une carte géographique (en exploitant les résultats d’autotest par rapport à la position géographique) ou sur un calendrier (résultats d’autotest par rapport à un horodatage). Cela permet d’identifier la cartographie des zones ou des moments temporels où les performances de l’équipement ne seront pas nominales. D’autres conditions, par exemple météorologiques, sont corrélées avec la cartographie des zones ou des moments temporels. Le système en ce cas permettra de discriminer un non fonctionnement lié à un problème de l’équipement ou d’un de ses composants ou d’un problème externe. Dans un mode de réalisation, le système fournit à l’avance une information de la durée/zone où le fonctionnement sera perturbé (ou a minima une information de contexte devant permettre à un opérateur d’estimer cette durée/zone).

The processing and analysis of the data in step 72 make it possible to determine in step 74 a plurality of K operating levels, comprising at least one nominal operating level and one operating level degraded with respect to the nominal operating level. . In addition, it is also contemplated that the operating levels include one or more operating levels optimized with respect to the nominal operating level.

The nominal level is a level for which the equipment provides satisfactory results, for example exhibiting measurement accuracy with a first predetermined error rate.

A degraded level corresponds to a measurement accuracy having a second error rate greater than the first predetermined error rate.

An improved level corresponds to a measurement accuracy having a third error rate lower than the first predetermined error rate

By way of nonlimiting example, we consider K = 3 operating levels, for example a first level N- \ of nominal operating, a second level N 2 in which the measurement accuracy of the equipment is degraded as explained below. above and a third operating level N 3 very severely degraded.

A map of operating levels as a function of several parameters representative of conditions of use is then generated in step 76.

The mapping distinguishes zones, according to their location in space, from parameters representative of conditions of use, each zone having an associated operating level for a given set of conditions of use.

In one embodiment, the zones are positioned according to their geographic location.

However, it should be noted that the operating areas defined in the map are not necessarily geographical areas, but areas defined as a function of the values ​​or ranges of values ​​of the parameter or parameters representative of a chosen condition of use ( ex: temporal ...). The zones may also vary with the environment in the broad sense (weather, radio environment, etc.).

The map generated is then used (step 78) to improve the performance of the item of equipment or items of equipment of the family of items of equipment considered, by reinjection into the items of equipment.

By way of schematic example, a mapping 80 of operating levels is illustrated in FIG. 4.

The cartography 80 corresponds to a given zone, for example geographical, and comprises a division into geographical zones, each point P of a zone represented having spatial coordinates in a geolocation frame of reference. The cartography shown schematically in FIG. 4 is two-dimensional, but as a variant the points are represented in a three-dimensional or higher order frame of reference.

Each zone represented ZZ 2 , Z 3 has an associated operating level, for example the level
for the zone Z the level N 2 for the zone Z 2 and the level N 3 for the zone Z 3 , when the parameters defining conditions d 'predetermined use take respective values ​​C 1; C 2 , C 3 , C 4 .

In the event of a change in the conditions of use, the division into zones may be modified.

For example, the geographical area considered is squared in elementary blocks 82, and for each block, an associated operating level as a function of values ​​of each condition of use is stored.

The size of an elementary block is variable and chosen as a function, for example, of the functionalities of the equipment and of the type of parameters representative of environmental conditions.

For example, when the condition of use is "temperature", operating levels according to temperature ranges are distinguished.

Likewise, when the condition of use is meteorological, for example operating levels are distinguished as a function of conditions such as rain of different intensities, snow or dry weather.

An operating level determination function makes it possible to calculate, from several parameter values ​​associated with the conditions of use, an operating level for each elementary block.

For example, the operating level determination function selects the most degraded operating level among the operating levels associated with the respective values ​​C 1; C 2 , C 3 , C 4 for a given block 82.

Multiple uses of such a mapping are possible.

For example, cartography can be used to plan a route requiring the use of given equipment. Indeed, if it is observed that the level of

operation of the equipment is degraded in a given geographical area, a route avoiding the relevant geographical area can be provided.

In general, at any time, an event can be compared with the content of the map, in order to anticipate the taking into account of this event.

For example, mapping makes it possible to alert an operator in real time of the current and future operating levels of an equipment, as well as the causes of the operating level, nominal, degraded or improved, of the equipment, to allow proper decision making.

In one embodiment, step 78 consists in transmitting the mapping of operating levels to the equipment 6, using the wireless communication protocol making it possible to communicate between the computing system 4 and the equipment 6. This having The objective is to allow even more efficient operation of the equipment 6.

As a variant, the transmission of the mapping of operating levels is carried out via a wired link during a maintenance phase.

FIG. 5 is a flowchart of a method of increasing the performance of a device in one embodiment.

This method is implemented by the equipment 6.

As a variant, the method is implemented by an on-board computer of a control and piloting system on board the carrier on which the equipment is on board.

During a first step 90, the equipment receives and stores the mapping of the operating levels previously calculated by a calculation system, either for this equipment specifically, or for the family of equipment.

Step 90 is followed by a step 92 of obtaining sets of equipment adjustment parameters for each operating level.

A set of tuning parameters associated with a given operating level is a set of parameters defining equipment settings that are chosen to maximize the operating capability of the equipment relative to the given operating level.

In one embodiment, the sets of adjustment parameters are transmitted at the same time as the mapping of the operating levels.

As a variant, the sets of adjustment parameters are calculated by the equipment, or stored in the equipment beforehand, for example during manufacture.

Step 92 is followed by a step 94 for recovering values ​​of parameters representative of conditions of use, then making it possible to use the mapping of operating levels previously recorded.

For example, during the movement of the carrier, these are parameters of geolocation, temperature, humidity, provided by sensors 12a to 12e installed on board the carrier.

In addition, other parameters such as environment parameters (eg meteorological or geographic) are provided.

The parameter values ​​obtained define the current conditions of use.

The mapping of the operating levels, previously received and stored, is then used in step 96 to determine the operating level of the equipment, according to the conditions of use. When a geolocation parameter has been used to construct the cartography, the information on the geographical position of use of the equipment is also used.

When the wearer is moving, the determined operating level is the current level.

It is then checked in step 98 whether the current operating level is the nominal level.

If the operating level is nominal, step 98 is followed by step 102 described below.

If the level is a degraded level, step 98 is followed by a step 100 consisting in issuing an alert, preferably accompanied by a report detailing the conditions of use and the level of operation.

The alert can be issued on a man-machine interface of the equipment, or transmitted to the on-board control and piloting system for operation. Typically, the alert is intended for an operator for decision making. This alert escalation can be a complement to the operator or the system providing them with this increased information, in addition to usual information that may meet operational safety requirements. In this case, it is up to the operator or the system to decide on the behavior in the face of these potentially inconsistent feedback.

The control and piloting system transmits the alert to the operator or performs an action to take preventive measures, for example the triggering of other equipment, a modification of the emitted powers or a modification of the route.

Thus, a degraded operating level is dynamically taken into account in real time to improve control and piloting.

Likewise, it is possible to display a temporary malfunction alert in a given area, and to inform the operator of the reasons for such a temporary malfunction. For example, the temporary malfunction can be localized spatially or due to a meteorological disturbance, without failure of a hardware component of the equipment. In this case, the operator has clear information and, in certain operational situations, can ignore the alert. Advantageously, the equipment can be re-used after leaving a degraded operating zone.

If the determined operating level is an improved level (greater than the necessary quality as estimated either by definition or by operator action), information intended for the operator is displayed in step 100. Preferably, The information comprises one or more adjustment parameters making it possible to operate the equipment with a less efficient operating level, to save, if necessary, its electrical consumption, its usage time or other resources used by the equipment. This is in particular advantageous for portable battery-powered equipment.

Step 100 is followed by a step 102 for updating, where appropriate, the adjustment parameters of the equipment as a function of the determined operating level, whether it is a degraded operating level, improved or nominal operating level.

Thus, if several sets of adjustment parameters are available, the use of mapping makes it possible to apply the most suitable adjustment parameters according to the operating level, in order to optimize the operating performance of the equipment, and especially to save resources. As a variant, the choice of applying other adjustment parameters is left to the operator, after having provided him with the operating level information.

Step 102 is followed by step 94 previously described for values ​​of parameters representative of conditions of use.

As a variant or in addition, in step 98, the determined operating level is compared with the operating state indicated by the self-test of the equipment. This advantageously enables the operator to manage any alert raised by the self-test thanks to additional information relating to the conditions of use, and to ignore, if necessary, a temporary alert.

It should be noted that the method described above also applies to a dynamic modification of the route by a control and piloting system during the movement of the carrier.

Indeed, the conditions of use, in particular the environmental conditions, on a previously planned route can be anticipated, for example by meteorological forecasts when this environmental condition affects the level of operation of the equipment.

It is then possible to estimate, from the map of stored operating levels, the operating levels planned for a later portion of the route, as a function of predicted environmental conditions, and to modify the route if this is the case. is possible, to avoid areas of degraded equipment operating level or to search for areas of higher operating level.
