Description Title of the invention: Optical transponder intended to contribute to monitoring the state of at least one internal device contained in a communicating container, communicating container and communication system. technical field

[0001] The present invention relates to a transponder intended to contribute to a sur- monitoring the state of at least one internal device, in particular a pyro- device technical, contained within a communicating container and a communication system. State of the art

[0002] It is currently accepted that one of the main physical parameters determining the The aging of a pyrotechnic device is determined by the temperature at which it has been subjected to this device throughout his life.

[0003] — The aging models of these pyrotechnic devices are therefore based princi- palement on the application of Arrhenius' law. The application of this law allows to estimate at what point an energetic material of the pyrotechnic device subjected to A temperature variation will begin to significantly lose stability.

[0004] These energetic materials can take various forms: propellants, primary explosives and initiating materials such as boosters, com- vivid redox positions, slow redox compositions such as by for example smoke bombs or illuminating compositions, secondary charges of the type military, etc.

[0005] — By way of non-limitation, a pyrotechnic device may be an artillery rocket (primary charge), an artillery shell (secondary charge), a missile (primary charge, secondary and propellant), an MK80 / Paveway type bomb kit (primary and secondary), a rocket (propulsive charge), a smoke grenade (slow redox reaction), a flare (slow redox reaction), a distress flare (slow redox reaction), a firework bomb (containing illuminating and propellant compounds), an anti-tank mine (ejection charge, primary and secondary charge), etc. The material(s) energ- Gétiques are indicated in parentheses.

[0006] The instability of energetic materials is a major risk to the safety of users users of pyrotechnic devices employing them. This risk is all the more pronounced. that the energetic material has a supply of kinetic energy through impacts, vi- accelerations or accelerations resulting from the handling of such pyrotechnic devices. This is why the regulations concerning the operation of pyrotechnic devices techniques including energetic materials require operators to control the aging of these materials by any useful means in order to remove from service any pyrotechnic device that may present an increased risk to its users. In order to address this safety issue, and since the major factor in the aging of energetic materials is essentially temperature, devices for measuring the physical parameters characteristic of aging have been developed. Although the supply is currently very diverse, these measurement devices face another regulatory constraint, which is the prohibition of any emission of radioelectric waves in the immediate vicinity of pyrotechnic devices. Pyrotechnic devices comprise, on the one hand, at least one element containing an energetic material, and on the other hand, at least one ignition element capable of triggering the reaction of this energetic material. A significant proportion of ignition elements currently on the market are at least partially electronically controlled. As such, they exhibit an inherent sensitivity to electromagnetic radiation. The exposure of such pyrotechnic devices to electromagnetic radiation therefore presents a major safety risk for operators of such devices. Although standards do exist to meet the safety needs of users of pyrotechnic devices in so-called far electromagnetic fields, radio emission in the immediate vicinity (less than a few meters) of a pyrotechnic device is currently prohibited, because it is poorly understood. This is why, to date, operators of automatic electronic environmental monitoring devices for pyrotechnical environments only have wired connections to collect data from these devices. Due to constraints on the location of pyrotechnical storage sites, which impose maximum quantities of energetic materials per storage facility and a minimum distance between them, such sites are generally very geographically dispersed. The costs of installing permanent wired networks between storage facilities are therefore usually prohibitive, necessitating manual recording of measurements from the data loggers of the monitoring devices, facility by facility. Furthermore, this type of work entails preparatory, documentation, and regulatory constraints. This tedious task offers no added value.Furthermore, its nature limits the frequency of data collection and complicates the management of a fleet of sensors and measuring devices. This can lead to a lack of alerts in case of failure and an inability to configure measuring devices in bulk, among other things. This complexity also necessitates a limited deployment of such recorders. data is used to limit the time users spend downloading data stored in warehouses. Therefore, it is practically impossible to measure the evolution of physical parameters at the scale of each pyrotechnic device, which sometimes leads to the mistaken assumption that a measurement at a specific point in the warehouse is representative of the situation of each pyrotechnic device stored there. The lack of spatial and temporal granularity in measurements currently prevents the effective detection of short-duration transient events and provides an imperfect view of the evolution of physical quantities at the scale of a pyrotechnic device. Consequently, the imprecise assessment of the aging of pyrotechnic devices by an operator leads them to adopt significant safety margins, which prove costly. Description of the invention The present invention solves this problem by offering a communication compatible with operation in a pyrotechnic environment and allowing, among other things, the recording of such measurements without or with human intervention and without requiring significant infrastructure costs.

It is intended to equip a communicating container 6 that may be stored in a warehouse. As shown in [Fig. 11], the communicating container 6 can be equipped with one or more optical transponders 1. The communicating container 6 is part of an optical communication system 16 ([Fig. 10]) intended to monitor the state of at least one internal device 7, such as a pyrotechnic device, contained within the communicating container 6. The optical communication system 16 may include one or more communicating containers 6. The optical transponder(s) 1 are intended to contribute to monitoring the state of at least one internal device 7. contained in a communicating container 6. The optical transponder(s) 1 are configured to receive at least one SLI light signal and to emit one SL2 light signal. The SLI light signal(s) may be in the form of light pulses. The optical communication system 16 includes at least one communicating container 6. The communicating container(s) 6 are intended to contain at least one internal device 7. The optical communication system 16 also includes a monitoring system 12 contributing to the monitoring of at least one first physical parameter characterizing an instantaneous physical state of the inside of the communicating container 6 and / or at least one second physical parameter characterizing an instantaneous physical state of the internal device(s) 7 contained in the communicating container 6. The first physical parameter(s) may correspond to the temperature in the communicating container 6 and / or the pressure in the communicating container 6 and / or a humidity level in the communicating container 6. The second physical parameter(s) may correspond to physical parameters representative of the aging of the internal device(s) 7, such as the temperature of the internal device(s) 7 and / or the humidity level of the internal device(s) 7. The monitoring system 12 includes at least one monitoring transponder 132 configured to receive at least one SL2 light signal emitted by the optical transponder(s) 1 equipping the communicating container(s) 6. The communicating container(s) 6 can be placed in pyrotechnic storage warehouses for storage. Depending on the type of internal device 7 contained in the communicating container(s) 6, these communicating containers 6 can be arranged in different ways when there are several communicating containers 6. For example, they can be stacked with a maximum of two to three communicating containers 6 per stack. Aisles can be provided between the stacks to facilitate the maneuvering of lifting equipment. In a first embodiment of the optical communication system 16 ( [Fig.10]), the monitoring system 12 includes at least one optical base station 13 and a concentrator 14. [Fig.10] represents an example of a generic architecture of a storage warehouse equipped with the optical communication system 16. The optical base station(s) 13 ([Fig. 12]) include the monitoring transponder(s) 132. The monitoring transponder(s) 132 of the optical base station(s) 13 include at least one monitoring transducer 130 configured to receive at least one SL2 light signal(s) emitted by the optical transponder(s) 1 of the communicating container(s) 6 and to emit at least one electrical signal SE8 which is representative of the light signal(s) SL2. The concentrator 14 ([Fig. 13]) includes a receiving unit 140 configured to receive the electrical signal(s) SE8 emitted by the optical base station(s) 13. The concentrator 14 also includes a processing unit 141 configured to process at least one electrical signal SE9 from the electrical signal(s) SE8. The electrical signal(s) SE9 are representative of the electrical signal(s) SE8. Processing a second electrical signal from a first electrical signal corresponds to a translation of the first electrical signal into a second electrical signal that is representative of the first electrical signal, that is, that contains the same information. This translation makes the first electrical signal generated by a first device usable by a second device that receives the second electrical signal. The concentrator 14 further includes a transmission unit 142 configured to transmit the electrical signal(s) SE9 to a user device 15. The optical base stations 13 can form a network designed to provide controlled and continuous coverage, enabling communication between said optical base stations 13 and the communicating container(s) 6. The optical base stations 13 can be synchronized with each other by means of the concentrator 14. The concentrator 14 can thus ensure the upstream and downstream transmission of information to and from the communicating containers 6. A pyrotechnical warehouse can therefore be equipped with one or more optical base stations 13, depending on the coverage requirements. The concentrator 14 can transmit the electrical signal(s) S9 to the user device 15 for data processing or fleet management of the communicating container(s) 6. A light signal SL2 from the same communicating container 6 can be received simultaneously by at least two optical base stations 13. The concentrator 14 is configured to detect that a light signal SL2 emitted by a communicating container 6 is received by at least two optical base stations 13. The concentrator 14 is then configured to take into account only one of the light signals SL2 emitted by the same communicating container 6 and received by several optical base stations 13. The monitoring transponder(s) 132 of the optical base station(s) 13 may further include a monitoring transducer 131 configured to receive at least one electrical signal SE1O from the concentrator 14 and to transmit the light signal(s) SL2 to at least one optical transponder 1 of at least one communicating container 6.The concentrator 14 may further include a receiving unit 143 configured to receive at least one electrical signal SE11 from the user device 15, a processing unit 144 configured to process the electrical signal(s) SE10 from the electrical signal(s) SE11 and a unit of . transmission 145 configured to transmit the SE10 electrical signal(s) to the optical base station(s) 13. In a second embodiment of the optical communication system 16, the monitoring system 12 can be a portable maintenance device, as shown in [Fig. 2]. In this second embodiment, the monitoring transponder(s) 132 of the monitoring system 12 include at least one monitoring transducer 130 configured to receive at least one SL2 light signal(s) emitted by at least one optical transponder 1 of at least one communicating container 6 and to emit at least one SE8 electrical signal that is representative of the SL2 light signal(s). The monitoring system 12 further includes an information unit 133 configured to inform a user of the first and / or second physical parameters based on the SES electrical signal(s).Information unit 133 may correspond to a display unit 133 configured to display a representation of the first physical parameter(s) and / or the second physical parameter(s) from the electrical signal(s) SES. In this second embodiment, the monitoring transponder(s) 132 may further include a control element 134 configured to transmit at least one electrical signal SE10 representing at least one control command. The control command may correspond to a request to transmit the first physical parameter(s) and / or the second physical parameter(s) of the communicating container(s) 6. The monitoring system 12 further includes a monitoring transducer 131 configured to receive the electrical signal(s) SE10 from the control element 134 and to transmit the light signal(s) SLI to at least one optical transponder 1 of at least one communicating container 6. The two embodiments of the optical communication system 16 described above can be combined. It is indeed possible to use a portable maintenance device according to the second embodiment in a warehouse equipped with the optical communication system 16 according to the first embodiment. An example of the optical transponder(s) 1 intended to equip the communicating container(s) 6 is shown in [Fig.1]. The optical transponder(s) 1 comprise at least one receiving element 2 configured to receive at least one SLI light signal from the optical communication system 16 and to emit at least one electrical signal SE1 that is representative of the SLI light signal(s). The SLI light signal(s) represent at least one control command. The control command may correspond to a request to transmit at least one first physical parameter characterizing an instantaneous physical state of the inside of the communicating container 6 and / or a second physical parameter characterizing an instantaneous physical state of the internal device(s) 7 contained in the communicating container 6. The command order may correspond to a request to change the parameterization of the communication system 16. According to a first embodiment of the optical transponder 1, the receiving element 2 can be a transducer. The transducer 2 can include a collecting lens 20, an optical filter 21, and a photodiode 22. The collection lens 20 is arranged to receive the SLI light signal(s) at a predetermined opening angle of the collection lens 20. For example, the opening angle is predetermined so that the received SL1 light signal(s) come from a larger area than the active surface of the photodiode 22. The collection lens 20 can also have a protective role against shocks. The optical filter 21 is configured to filter the SLI light signal(s) received by the collecting lens 20. The optical filter 21 is configured to block frequencies of the SLI light signal(s) outside a predetermined frequency range. For example, the frequency range is determined so that the optical filter 21 eliminates parasitic components of the SLI light signal(s), such as ambient and artificial light. The optical filter 21 then allows only a portion of the light spectrum of the SLI light signal(s) corresponding to a specific operating frequency range of the photodiode 22 to be retained. By way of non-limiting example, the photodiode 22 operates in a frequency range from the visible spectrum to the infrared spectrum, specifically between 400 nm and 1 mm. The frequency range is chosen according to the lighting conditions of the warehouse in which the communicating container(s) 6 are likely to be stored. In particular, the frequency range is chosen so as to lie outside the spectrum of ambient light pollution such as artificial lighting. Photodiode 22 is arranged to receive the SLI light signal(s) filtered by optical filter 21. Photodiode 22 is capable of generating the SE1 electrical signal(s) and transmitting the SE1 electrical signal(s) to control unit 4. The transponder(s) also include a transmitting element 3 configured to receive at least one electrical signal SE2 and to emit at least one light signal SL2 which is representative of the electrical signal(s) SE2. The light signal(s) SL2 are intended to be transmitted by the transducer 3 to the optical communication system 16. According to the first embodiment of the optical transponder, the emitting element 3 can correspond to a transducer. The transducer 3 comprises an electro- diode luminescent 32 arranged to receive the electrical signal(s) SE2. The light-emitting diode 32 is capable of generating and emitting at least one light signal SL2 which is representative of the electrical signal(s) SE2. According to a second embodiment of the optical transponder 1, the transmitting element 3 may include a backscattering device configured to receive the electrical signal(s) SE2 and emit the light signal(s) SL2 ([Fig. 14]). For example, the backscattering device includes at least one reflector 34 configured to reflect the light signal(s) SL1 and a shutter 35 configured to be, alternatively, in a position preventing the light signal(s) SL1 from reaching the reflector 34 and a position allowing the light signal(s) SL1 to reach the reflector 34. The light signal(s) SL2 correspond to the light signal(s) SL1 reflected by the reflector 34. The position of the shutter 35 is a function of the electrical signal(s) SE2. This second embodiment of the optical transponder 1 is described in more detail below. The optical transponder(s) | further include a control unit 4. The control unit 4 includes a receiving module 40 configured to receive the electrical signal(s) SE] from the receiving element 2. The optical transponder(s) 1 also have a receiving module 41 configured to receive from at least one sensor 9, 10 housed in the communicating container 6 (equipped with the optical transponder(s) 1) at least one electrical signal SE3 representative of at least one first physical parameter characterizing an instantaneous physical state of the inside of the communicating container 6 and / or a second physical parameter characterizing an instantaneous physical state of the internal device(s) 7 intended to be contained in the communicating container 6. The optical transponder(s) 1 further comprise a processing module 43 configured to process the electrical signal(s) SE2 representative of the electrical signal(s) SE3 as a function of the electrical signal(s) SE1. In addition, the optical transponder(s) 1 comprise a transmission module 42 configured to transmit the electrical signal(s) SE2 to the transmitting element 3. Furthermore, the control unit 4 may also include a processing module 44 and a transmission module 45. The processing module 44 is configured to process at least one electrical signal SE4 representative of the electrical signal(s) SE1. The transmission module 45 is configured to transmit the electrical signal(s) SE4 to the sensor(s) 9, 10 housed in the communicating container 6. Furthermore, the emitting element 3 may further include an optical filter 31 and an emitting lens 30. The optical filter 31 is configured to filter the SL2 light signal(s). The optical filter 31 is configured to block frequencies of the or The SL2 light signals are emitted from outside a predetermined frequency range. The emitting lens 30 is configured to emit the SL2 light signal(s) filtered by the optical filter 31. The emitting lens 30 can have a predetermined aperture angle. It can also protect the light-emitting diode 32 in the optical transponder 1. As a non-limiting example, the optical filter 31 corresponds to a bandpass filter in order to narrow the frequency spectrum of the light signal(s) SL2 emitted by the light-emitting diode 32. This also prevents parasitic light signals that may be emitted by the light-emitting diode 32 from being emitted by the optical transponder 1. Furthermore, the receiving element 2 may also include a demodulator 23 configured to translate the electrical signal(s) SE1 generated by the photodiode 22 so that they can be used by the control unit 4. Advantageously, the demodulator 23 is configured to translate and transmit the translated electrical signal(s) SE1 to the control unit 4 and to wake up the control unit 4 if the command command includes a predetermined preamble. Conditioning the transmission of the electrical signal(s) SE1 by the demodulator 23 allows for energy savings. The demodulator 23 may thus include a very low-power analog detection module (not shown) capable of waking up the control unit 4 with a wake-up signal SR in order to prepare the optical transponder 1 to receive an incoming communication via the light signal(s) SLI.This detection occurs as soon as an SLI light signal is received by the optical transponder 1 on a predetermined frequency and / or a predetermined preamble in the command sequence. A wake-up signal SR emitted by the demodulator 23 can also be emitted by the control unit 4 downstream of the optical transponder 1 with the electrical signal SE1. The preamble can correspond to a line of symbols or a waiting time between two receptions of the SLI light signal. The transmitting element 3 may also further include a modulator 33 configured to translate the electrical signal(s) SE2 produced by the control unit 4 so that they can be used by the light-emitting diode 30. The monitoring transponders 132 of the optical base stations 13 may also be identical to the optical transponders 1. However, the monitoring transponders 132 may include different features. For example, the optical filter 21 or 31, photodiode 22, and / or light-emitting diode 32 may operate at different light frequencies so that the SLI light signal(s) and the SL2 light signal(s) have different respective light frequencies. This configuration allows bidirectional communication. Advantageously, the SLI and SL2 light signals can be oriented so as to look mostly towards the ceiling of the storage warehouse. According to the second embodiment of optical transponder | ([Fig.14], [Fig.15] and [Fig.16]), the optical transponder 1 further comprises a collection lens 38 arranged to receive the first SLI light signal(s), an optical filter 36 configured to filter the SLI light signal(s) received by the collection lens 38. Optical filter 36 is configured to block frequencies of the SLI light signal(s) outside a predetermined frequency range. In this second embodiment, the optical transponder | also includes a beam splitter lens 39 configured to separate the SLI light signal(s) into two secondary light signals SL11 and SL12 ([Fig.15]). In this second embodiment, the emitting element 3 comprises a reflector 34 configured to reflect a secondary signal SL11 from the two secondary light signals SL11 and SL12 and a shutter 35 configured to be alternately in a closed position in which the shutter 35 prevents the secondary light signal SL11 from reaching the reflector 34 and in an open position in which the shutter 35 allows the secondary light signal SL11 to reach the reflector 34. The closed position and the open position of the shutter 34 can correspond, respectively, to an opaque state of the shutter 34 in which said shutter 34 prevents the secondary light signal SL11 from reaching the reflector 34 (it is opaque to the secondary light signal SL11) and to a transparent state of the shutter 34 in which said shutter 34 allows the secondary light signal SL11 to reach the reflector 34 (it is transparent to the secondary light signal SL11). In this second embodiment, the receiving element 2 comprises a photodiode 37 arranged to receive a secondary light signal SL12 from the two secondary light signals SL11 and SL12. The receiving element is capable of generating the electrical signal(s) SE1 and transmitting the electrical signal(s) SE1 to the control unit 4. In this second embodiment, the optical transponder 1 may further include a processing unit 394, a wake-up unit 393 and a transmission unit 392. The processing unit 394 is configured to transmit the electrical signal(s) SE1 to the control unit 4 and to receive the electrical signal(s) SE2 from the control unit 4. The processing unit 394 can be powered by a power supply device 395. The 393 alarm clock unit is configured for: - receive the SE1 electrical signal(s), - to develop an SE12 electrical wake-up signal intended to be transmitted to the unit processing 394 if the wake-up unit 393 detects a predetermined pulse sequence in the electrical signal(s) SE1. The predetermined pulse sequence can correspond to a series of light pulses emitted at a predetermined frequency. The transmission unit 392 is configured to receive the electrical signal(s) SE1 generated by the photodiode 37 and transmit the electrical signal(s) SE1 to the processing unit 394. The processing unit 394 is capable of receiving the electrical signal(s) SE1 from the transmission unit 392 if the processing unit 394 has received the electrical wake-up signal SE12. Furthermore, in this second embodiment, the processing unit 394 can be capable of transmitting to the shutter 35 an electrical control signal SE21. The electrical control signal SE21 is capable of commanding the shutter 35 to be alternately in the open position and in the closed position according to the electrical signal(s) SE2 so that the light signal(s) SL2 are representative of the electrical signal(s) SE2. In a variant of the second embodiment, the shutter 35 comprises several shutter elements arranged in a matrix. Each shutter element can be independently controlled between an open and a closed position. In this variant, the electrical shutter control signal SE21 includes sub-commands to independently control each of the shutter elements. Coupled with pulse-amplitude modulation (PAM) of the opening type, this variant allows for the encoding of a greater number of symbols per unit of time, thereby increasing the communication rate. The shutter 35 may include a liquid crystal display controlled by the SE21 shutter control electrical signal. For example, this liquid crystal display can alternatively be found: - in an opaque state in which the SE21 signal commands the liquid crystal display to be opaque to the secondary light signal SL11 (the SL11 signal cannot pass through the liquid crystal display to reach the reflector 34), - in a transparent state in which the SE21 signal commands the liquid crystal display to be transparent to the secondary light signal SL11 (the SL11 signal can pass through the liquid crystal display to reach the reflector 34). In this second embodiment, the optical transponder 1 may also include a bandpass filter 391 configured to filter the electrical signal(s) SE1 emitted by the photodiode 37. This filtering prevents parasitic electrical signals that may be produced by the photodiode 37 from being transmitted to transmission unit 392 and wake-up unit 393. Liquid crystal displays can be either monochrome or color. In the case of a color display, the liquid crystal can be transparent or opaque depending on the wavelength of the light signal that can pass through it. The communicating container 6 capable of receiving at least one internal device 7 includes at least one optical transponder 1. The communicating container 6 may also include at least one optical coordinating device 8. The optical coordinating device 8 may be part of an optical transponder 1. To optimize optical coverage between the optical transponders of a communicating container 6 and the monitoring system 12 of a pyrotechnical warehouse, two mounting configurations for these optical transponders on the communicating container 6 can be considered. Both configurations are shown in [Fig. 11]. Configuration (a) involves four optical transponders 1 mounted on the four faces of the communicating container 6. This configuration may, if necessary, involve more than one optical transponder 1 per face of the communicating container 6 if its geometry requires it. Configuration (b) involves four optical transponders 1 mounted on the four lateral corners of the communicating container 6. Depending on the geometry of the communicating container 6, this configuration may involve more than one optical transponder 1 per corner. According to one configuration, all faces and all edges of a communicating container 6 can be equipped with an optical transponder 1, including the upper face and the lower face of the communicating container 6. The optical coordinator device 8 coordinates the optical transponders 1 when the communicating container 6 is equipped with several optical transponders 1. The optical coordinator device 8 can also be configured to electrically supply the optical transponder(s) 1. The coordinating device 8 comprises a receiving unit 80, a receiving unit 81, a processing unit 82 and a transmission unit 83 ([Fig.3] and [Fig.4]).

The receiving unit 81 is configured to receive at least one electrical signal SE6 representative of the second physical parameter(s) characterizing an instantaneous physical state of the internal device(s) 7 intended to be contained in the communicating container 6. The receiving unit 80 and the receiving unit 81 can receive electrical signals SES and SE6 from several optical transponders 1 of several communicating containers 6. In one embodiment, the receiving unit 80 and the receiving unit 81 can be a single receiving unit configured, on the one hand, to receive at least one electrical signal SES representative of the first physical parameter(s) characterizing an instantaneous physical state of the inside of the communicating container 6 and, on the other hand, to receive at least one electrical signal SE6 representative of the second physical parameter(s) characterizing an instantaneous physical state of the internal device(s) 7 intended to be contained in the communicating container 6. The processing unit 82 is configured to process the SE3 electrical signal(s) from the SES electrical signal(s) and the SE6 electrical signal(s). The transmission unit 83 is configured to transmit the electrical signal(s) SE3 to the optical transponder(s) 1. Furthermore, the optical coordinating device(s) 8 may also include a receiving unit 84, a processing unit 85 and a transmitting unit 86. The receiving unit 84 is configured to receive the SE4 electrical signal(s) from the optical transponder(s) 1. The processing unit 85 is configured to process at least one SE7 electrical signal representative of the SE4 electrical signal(s). The transmission unit 86 is configured to transmit the electrical signal(s) SE7 to the sensor(s) 9, 10. In one embodiment, the receiving unit 80, the receiving unit 81 and the transmitting unit 86 can be a single interface unit configured for: -receive at least one SES electrical signal representative of the first physical parameter(s) characterizing an instantaneous physical state from inside the communicating container 6 -receive at least one SE6 electrical signal representative of the second physical parameter(s) characterizing an instantaneous physical state of the internal device(s) 7 intended to be contained within the communicating container 6, and - transmit to sensor(s) 9, 10 the electrical signal(s) SE7. The communicating container 6 may also include at least one sensor 9 and a monitoring device 11. According to one embodiment, it may also include a sensor 10. The sensor(s) 9 ([Fig.6]) comprise a measurement module 90 configured to measure the first physical parameter(s) characterizing an instantaneous physical state of the interior of the communicating container 6 and an elaboration module 91 configured to generate the SES electrical signal(s) representative of the first physical parameter(s) measured. Without limitation, the sensor(s) 9 may correspond to one or more temperature sensors and / or one or more pressure sensors and / or one or more humidity sensors. In the case where the communicating container 6 includes the sensor 10, the sensor(s) 10 ([Fig.7]) include a measurement module 100 configured to measure the second physical parameter(s) characterizing an instantaneous physical state of the internal device(s) 7 likely to be contained in the communicating container 6 and a processing module 101 configured to process the electrical signal(s) SE6 representative of the second physical parameter(s) measured. The monitoring device 11 includes at least one receiving unit 110, one distribution unit 111, one transmission unit 112 and one storage unit 116. The receiving unit 110 is configured to receive the SES electrical signal(s) and, in the case where the communicating container 6 includes the sensor 10, the SE6 electrical signal(s). The distribution unit 111 is configured to distribute the SES electrical signal(s) and, in the case where the communicating container 6 includes the sensor 10, the SE6 electrical signal(s). The transmission unit 112 is configured to transmit to the optical co-computer device(s) 8 the electrical signal(s) SES and, in the case where the communicating container 6 includes the sensor 10, the electrical signal(s) SE6. The storage unit 116 is configured to store the first physical parameters and / or the second physical parameters from the SES electrical signal(s) and / or the SE6 electrical signals, respectively. The distribution unit 111 is configured to distribute the electrical signal(s) SE5 and, in the case where the communicating container 6 includes the sensor 10, the electrical signal(s) SE6 between the transmission unit 112 and the storage unit 116. The monitoring device 11 may further include a receiving unit 113, a processing unit 114 and a transmission unit 115. The receiving unit 113 is configured to receive the SE7 electrical signal(s). The processing unit 114 is configured to process at least one electrical signal SES representative of the electrical signal(s) SE7. The transmission unit 115 is configured to transmit the electrical signal(s) SE8 to the sensor(s) 9, 10. The monitoring device 11 may also include a monitoring unit 117. This monitoring unit 117 is configured to detect an anomaly in the first physical parameters and / or the second physical parameters from the or SES electrical signals and / or SE6 electrical signal(s). An anomaly may correspond to an abnormal increase or decrease in temperature or pressure inside the communicating container 6 and / or the internal device(s) 7. The anomaly may be detected by the monitoring unit 117 by a temperature or pressure drift (too rapid an increase or decrease in temperature or pressure relative to a threshold). The anomaly may also correspond to a temperature that is too high or too low and / or a pressure that is too high or too low relative to a temperature threshold. When an anomaly is detected, the monitoring unit can send an electrical alert signal SA to the storage unit 116 capable of storing an alert message or directly to the optical transponder(s) 1. The communicating container 6 may also include a power supply 17 intended to power the optical coordinator device 8 and the monitoring device 11. The wake-up signal SR emitted by the demodulator 23 is capable of waking up the monitoring device 11 and the optical coordinator device 8. The monitoring device 11 may correspond to a data logger, such as a monitoring system 12 of the status and use of the internal device(s) 7 otherwise called HUMS (Health and usage monitoring system). In the example of [Fig. 4], the communicating container 6 is equipped with four optical transponders 1. The four optical transponders 1 are synchronized with each other by the optical coordinator device 8, which synchronizes their operation. The optical coordinator device 8 can also supply power to the four optical transponders 1. The monitoring device 11 can provide the optical coordinator device 8 with the first physical parameter(s) and / or the second physical parameter(s) stored in the storage unit 116. The monitoring device 11 can also provide the optical coordinator device 8 with the alert message(s). In [Fig. 4], the internal device is a complex munition.The complex munition is connected to the monitoring device 11 by an umbilical cord 18 and transmits to the monitoring device 11 the second physical parameter(s) characterizing an instantaneous physical state of the complex munition. Simultaneously, the monitoring device 11, connected to a sensor 9 corresponding to a thermometer, records the first physical parameter(s) from inside the communicating container 6, in particular the temperature. By way of non-limitation, the optical protocol encoding communication using the light signals SL1 and SL2 between the optical transponder(s) 1 and the optical base stations 13 can be designed so as to limit frame collisions when Several optical transponders 1 transmit an SLI light signal to the same optical base station 13 simultaneously. Each SL1 light signal transmitted to an optical base station 13 can trigger a return light signal representing an acknowledgment. The absence of this acknowledgment light signal can indicate that the communication failed, including a possible frame collision. The frames can be encoded with a short duty cycle to limit collisions. The system communicates using frequency modulation of the SLI and SL2 light signals, the carrier frequency being determined to be compatible with the receive rate of the optical base station(s) 13 as well as the different resonant frequencies of light pollution sources (primarily neon lighting). When a communicating container 6 communicates with an optical base station 13, it will prioritize the use of the most efficient optical transponder 1. Advantageously, in order to save the energy available in the power supply 17, only the optical transponder 1 located at least within the SLI light signal reception coverage of an optical base station 13 can be used for communication. The 16 communication system can be used in various applications. In a first example, it can be used in the case of a communicating container 6 used as a test bench container with an automated logbook, such as an electronic logbook (e-logbook). The communicating container 6 can correspond to the one shown in [Fig. 9]. The internal device 7 corresponds to a complex munition installed in the communicating container 6. In this example, the communication system 16 is capable of regularly transmitting diagnostic data, allowing for the detection of a drift in the operational performance of the complex munition or simply enabling the automatic completion of a logbook for the complex munition. This type of scenario can arise in the case of complex munitions carried on board an aircraft.Recording the impacts on the complex munition caused by aircraft movements such as landing can be a determining factor in the mechanical fatigue of the complex munition. Once installed in a communicating container 6 and stored, the complex munition can be connected to the monitoring device 11 of the communicating container 6 by an umbilical cord 18. The optical transponder(s) 1 communicate with the monitoring system 12 which transmits the information, in particular the recorded impacts, registered in flight by the complex munition to the user device 15. In a second example, the communication system 16 can be used in the case of communicating containers 6 capable of alerting to leaks. In order to better protect Some internal devices 7, such as complex munitions, are subject to specific storage conditions. The communicating containers 6 are pressurized to prevent moisture and particles from entering the communicating container 6. This pressure tends to decrease over time due to slight structural leakage in the communicating container 6, requiring operators to top up the pressure occasionally. A leak occurring without the operator's knowledge could expose the product to less-than-ideal storage conditions and compromise the operational performance of the communicating munition 6. In this example, the communicating container 6 is configured according to [Fig. 4], in which sensor 9 is a pressure sensor. The pressure data is recorded by the monitoring device 11 (in the storage unit 116).An SA alert signal is issued as soon as the monitoring unit 117 determines that the pressure level measured by the pressure sensor 9 falls below a certain threshold. The optical transponder(s) communicate with the monitoring system 12, which then transmits the SA alert signal to the user device 15. In a second example, the communication system 16 can be used to quickly locate a communicating container 6 among several communicating containers 6. In this example, the communicating container 6 is equipped with at least one light-emitting diode 19 configured to emit light in the visible spectrum, in a color highly visible to the eye (for example, a selected shade of green). The operator wishing to quickly identify a communicating container 6 selects it via an information system of the user device 15, which, through the monitoring system 12, informs the relevant communicating container 6 of this identification request. The communicating container 6 then flashes its visible light-emitting diode(s) 19 to quickly indicate its position to the user.
