Communication system and associated communication method

The present invention relates to a communication system and an assembly formed by a vehicle and such a communication system. The present invention also relates to a communication method and associated protective clothing.

It is common for teams of more than one person to intervene, under the supervision or responsibility of a remote supervisor, in situations where communication with the supervisor is difficult. This is, for example, the case when a rescue team intervenes in a fire or in a dangerous and / or noisy environment. The direction of the team by the supervisor, or the coordination of this team with other stakeholders are therefore questionable. In the event of a problem, it is then difficult for the supervisor to assess the situation and determine whether it is appropriate to intervene and if so under what conditions.

Radio communication systems exist, allowing the exchange of voice or video messages between the supervisor and the members of the team, but are not adapted to all situations. If the environment is noisy, the sounds emitted are likely to be muffled. In other cases, discretion requires the team to remain silent. The team members then communicate by gestures, which are generally not visible to the supervisor.

In addition, voice messages are intended to be analyzed immediately by the supervisor: in the event of carelessness, the information transmitted may be lost. Even if the information is stored on a medium, it is difficult to analyze it in the heat of the moment without risking inadvertently losing other information received during its analysis.

In many cases, communication between the members of an intervention team and their supervisor is therefore reduced to a minimum, and the analysis of the intervention of the team is carried out a posteriori, from reports made by the Members of the team. In the event that members of the team are injured or died during the intervention, information is therefore lost, and the analysis of the situation is incomplete, which limits the possibilities of improving techniques or procedures. intervention.

There is therefore a need for a communication system allowing the immediate transfer of information between one or more members of a team and a remote supervisor, which is reliable, while being adapted to a large number of situations.

To this end, a communication system is proposed comprising a centralization device and at least one set of sensors suitable for being carried by a first person, called a carrier, at least one sensor of the set of sensors being suitable for being secured to a member of the carrier and being suitable for measuring a value of a quantity relating to a movement of the corresponding member and for transmitting the measured value to the centralization device by radio frequency communication, the centralization device comprising a memory for storing an assembly gestures and a set of information, each gesture being associated, in the memory, with information, the centralization device being, moreover, configured to recognize, from the values received, a gesture made by the wearer and to transfer information associated with a second person, called a supervisor.

According to embodiments, the communication system comprises one or more of the following characteristics, taken in isolation or according to all technically possible combinations:

- the set of sensors includes at least one location device configured to determine a location of the wearer and the information associated with at least one gesture includes the location of the wearer when the wearer makes the gesture.

- the set of sensors includes at least one compass and the information associated with at least one gesture includes the direction in which a part of the wearer's body is oriented during the gesture.

- the set of sensors comprises at least one flexion sensor configured to measure an angle between two segments of an upper limb of the wearer.

the communication system comprises a first set of sensors carried by a first carrier and at least a second set of sensors carried by a second carrier, the centralization device being configured to recognize, from the values received, a gesture made by the first carrier and to transmit the information associated with the supervisor and the second carrier.

- the communication system includes an earpiece for each wearer, the centralization device being able to generate an audible message from a gesture made by the first wearer and to transmit the audible message to the auricle of the second wearer.

It is also proposed an assembly formed by a vehicle and a communication system as described above, the centralization device being embedded in the vehicle.

It is further proposed a communication method implemented by a communication system comprising at least one set of sensors carried by a first person, called a carrier, and a centralization device, at least one first sensor of the set. of sensors being secured to a member of the wearer, the centralization device comprising a memory for storing a set of gestures and a set of information, each gesture being associated, in the memory, with information, the method including the steps of:

• execution of a gesture by the wearer, • measurement, by at least the first sensor, of a value of a quantity relating to a movement of the corresponding member, • transmission of each measured value to the centralization device, • recognition, by the centralization device, of the gesture executed from the values received, and • transfer, by the centralization device, of the information associated with a second person, called a supervisor.

According to one embodiment, each gesture performed by a wearer is a gesture intended to be observed and interpreted by another wearer.

Protective clothing is also proposed comprising a set of sensors suitable for communicating with a centralization device by radiofrequency communication to implement a method as described above.

Characteristics and advantages of the invention will appear on reading the description which follows, given solely by way of nonlimiting example, and made with reference to the appended drawings, in which:

- Figure 1 is a schematic representation of a communication system comprising a plurality of garments,

- Figure 2 is a schematic representation of a set of garments of Figure 1, and

- Figure 3 is a flowchart of an example of a communication method implemented by the system of Figure 1.

A communication system 10 is shown in FIG. 1.

The communication system 10 is configured to allow information to be exchanged between at least a first person 15 called a carrier and at least a second person 20 called a supervisor.

The communication system 10 includes a centralization device 25 and, for each carrier 15, a set of sensors 30A, 30B.

An assembly is, for example, formed by the communication system 10 and a vehicle. In particular, the centralization device 25 is on board the vehicle.

Each carrier 15 is part of a team comprising a first carrier 15A and at least a second carrier 15B.

Each carrier 15 knows a set of gestures capable of being performed by the carrier 15.

“Gesture” is understood to mean a movement of at least part of the body of a wearer 15. In particular, a gesture includes at least one movement of a member of the wearer 15.

The term “member” is understood to mean a part of the body of the wearer 15 which is movable relative to other parts of the body of the wearer 15. In particular, the term “member” is intended to mean an upper member or a lower member.

An upper member is connected to a shoulder of the wearer 15. An upper member comprises an arm, an elbow, a forearm and a hand.

A lower limb is connected to a hip of the wearer 15. A lower limb includes a thigh, a knee, a leg, an ankle and a foot.

According to a specific embodiment, each gesture comprises a set of relative movements of segments of the same member of the wearer 15.

A segment is a part of a member that is movable relative to other parts of the same member. For example, a phalanx is a segment of a limb. The hand is a segment of a limb. The forearm is another example of an upper limb segment.

At least one gesture comprises a movement of an upper member of the wearer 15. In particular, each gesture comprises relative movements of segments of a single upper member of the wearer 15. For example, the gesture is formed by relative movements of segments of the right upper limb between them.

At least one gesture comprises a movement of at least one member of the wearer 15 towards a predetermined position. In particular, the gesture is defined by the relative positions of several segments of the same member of the wearer 15 at the end of the gesture. For example, the relative positions include relative positions of the phalanges of the same upper member of the carrier 15.

Each gesture is a gesture intended to be observed and interpreted by another wearer 15. In particular, the gesture has a meaning, that is to say that each gesture is planned so that the observation of the gesture corresponds to the transmission of information to another carrier 15.

For example, the gesture is identifiable, by the other carriers 15, by the position, at the end of the gesture, of at least part of the member of the carrier 15.

For example, a gesture ending in a position in which a hand of a wearer 15 is aligned, fingers extended, in the extension of the corresponding forearm, near an ear of the wearer 15 is associated with the "hear something" information. According to another example, when a hand is placed, outstretched, palm pointing down, above the eyes of a wearer 15, the information associated with the gesture is "look".

A recipient is associated with at least one item of information. The recipient is the person for whom the information is intended. For example, a recipient of information is supervisor 20. Alternatively, the recipient of information is each member of the team.

At least one piece of information is critical information. Critical information is information intended to be considered immediately by the people receiving the information.

The communication system 10 is configured to interpret the gestures made by the carriers 15. In particular, the communication system 10 is configured to recognize a gesture made by a carrier 15 and to transmit the information associated with the gesture to a person distinct from the carrier 15 who performs the gesture.

The supervisor 20 is assigned to supervise the actions carried out by the carriers 15.

As a variant, the supervisor 20 is a second carrier 15B. According to another variant, the supervisor 20 is a member of a team other than that of the first carrier 15A.

Each sensor 30A, 30B of the same set of sensors 30A, 30B is configured to be worn by one of the carriers 15. For example, each sensor 30A, 30B of the same set of sensors 30A, 30B is integrated in a garment intended to be carried by the corresponding carrier 15.

A set of garments 67 comprising a set of sensors 30A, 30B has been represented in FIG. 2. Each sensor 30A, 30B has been symbolically represented by a point in FIG. 2.

Each garment 67 is preferably a protective garment. In particular, each garment 67 is configured to protect the wearer 15 against a harmful event. For example, each garment 67 is flame retardant. As a variant, at least one garment 67 is padded and / or reinforced to withstand impacts or punctures.

According to the example of FIG. 2, the set of clothes 67 comprises a jacket 70 and two gloves 75. As a variant, the set of clothes 67 comprises a protective helmet.

As a variant, each sensor 30A, 30B is designed to be fixed directly to the carrier 15, for example by means of straps enclosing a part of the body of the carrier 15.

The set of sensors 30A, 30B comprises at least a first sensor 30A and at least a second sensor 30B.

Each first sensor 30A is configured to be secured to a member of the wearer 15. For example, the first sensor 30A is provided to be secured to a member of the wearer 15 when the associated garment 67 is worn by the wearer 15.

It is understood by "united" that a movement of the member corresponds to an identical and simultaneous movement of the first sensor 30A.

The first sensor 30A is configured to measure a value of a magnitude relative to a movement of the corresponding member.

The quantity is, for example, a quantity relating to a position of the limb.

A distance between a point of the member and another predetermined point is an example of a magnitude relative to a position of the member. Another example of magnitude relative to a position of the limb is the angle of a line carried by a segment of the limb with respect to a predetermined direction.

In particular, the quantity is a quantity relative to a relative position of two segments of the same member. The magnitude is, for example, an angle between two contiguous segments of a member of the carrier 15 to which the first sensor 30A is secured. For example, the magnitude is an angle between two phalanges of the carrier 15.

Two contiguous segments of the same member are two segments of the same member which are connected to each other by a joint.

As a variant, the size is an angle between a member and the trunk of the wearer 15, for example between the arm and the shoulder of the wearer 15.

The trunk is the central part of the human body. The trunk of the carrier 15 is connected simultaneously to the two arms and the two legs of the carrier 15.

Alternatively, magnitude is a direction in space.

According to one embodiment, at least a first sensor 30A comprises a compass configured to measure a direction in which a part of the body of the carrier 15 is oriented. For example, the first sensor 30A is configured to measure a direction in which a finger is pointed. Alternatively, the first sensor 30A is configured to measure a direction in which the head of the carrier 15 is oriented.

According to another variant, the first sensor 30A is configured to measure a direction in which the trunk of the carrier 15 is oriented.

"Direction" is understood to mean an orientation in space. For example, a direction in a horizontal plane is defined with respect to the North, South, East and West directions. A direction is defined absolutely, that is to say independently of the respective positions of the other parts of the body of the wearer 15.

As a variant, the quantity is a quantity relating to a displacement of a member of the carrier 15.

For example, greatness is an acceleration of the limb.

As a variant, the quantity is a speed of rotation of the member.

In such a variant, the first sensor 30A is a gyroscope.

Each second sensor 30B is configured to measure a value of a parameter of the carrier 15 which is not relative to a movement of a member of the carrier 15.

A second sensor 30B is, for example, configured to determine a location of the carrier 15. For example, the second sensor 30B considered is a GPS positioning module. GPS, or "Global Positioning System" (in French Global Positioning System) is a geolocation system operating at a global level and based on the exploitation of radio signals emitted by dedicated satellites.

Another second sensor 30B is configured to measure a value of a physiological parameter of the carrier 15. The physiological parameter is, for example, chosen from the group formed by a pulse of the carrier 15, a body temperature of the carrier 15 and a pressure carrier blood 15.

Each sensor 30A, 30B is configured to transmit the measured values to the centralization device 25.

For example, at least one item of clothing 67 comprises a first transmitter / receiver 80 configured to receive, from each sensor 30A, 30B, measured values and to transmit said values to the centralization device 25.

The first transmitter / receiver 80 is a radio frequency communication module. It is understood by "radiofrequency communication module" that the first transmitter / receiver 80 is configured to exchange data via a signal comprising at least one radiofrequency electromagnetic wave.

Radio frequency electromagnetic waves are electromagnetic waves with a frequency between 3 kHz and 3 GHz.

For example, the first transceiver 80 is configured to transmit data to the centralization device 25 using a WiFi communication protocol.

The first transmitter / receiver 80 is also configured to receive, by radio frequency communication, data from the centralization device.

For example, at least one item of clothing 67 includes a headset, and the first transmitter / receiver 80 is configured to receive, by radio frequency communication, sound messages intended to be transmitted by the headset to the wearer 15.

The centralization device 25 comprises a transmitter / receiver 35, a memory 40, a first computer 45, and a terminal 50.

The second transmitter / receiver 35 is configured to exchange data with each sensor 30.

The memory 40 is able to store a set of gestures. It is understood by “memorizing a set of gestures” that data relating to the positions, during the gesture, of the members which move during the gesture are memorized in the memory 40.

For example, the memory 40 includes, for each gesture stored in the memory 40, a set of identification values. The identification values are values of quantities each associated with a first sensor 30A.

The identification values are configured to allow the first computer 45 to recognize the corresponding gesture. For example, the identification values include, for each first sensor 30A, one or more ranges of possible values.

The memory 40 is, moreover, suitable for storing a set of information. Each piece of information is associated, in the memory 40, with the corresponding gesture

The first computer 45 is suitable for handling and / or transforming data represented as electronic or physical quantities in the memory 40 into other similar data corresponding to physical data in the memory 40, in registers or other types of display, transmission or storage devices.

According to the example of FIG. 1, the terminal 50 is distinct from the second transmitter / receiver 35, from the memory 40 and from the first computer 45. For example, the second transmitter / receiver 35, the memory 40 and the first computer 45 form a server 55 capable of exchanging information with the terminal 50.

The terminal 50 is, for example, a computer configured to communicate with the server 55.

The terminal 50 is capable of displaying, for the supervisor 20, information received from the first computer 45.

For example, the terminal 50 includes a second computer 60 and a man / machine interface 65.

The man / machine interface 65 includes, for example, a screen, a microphone and / or a speaker.

The operation of the communication system 10 will now be described.

A flowchart of the steps of a communication method, implemented by the communication system 10, has been shown in FIG. 3. The communication method includes a step 100 of performing a gesture, a step 110 of measuring , a step 120 of transmission, a step 130 of recognition, a step 140 of transfer, a step 150 of communication and a step 160 of broadcasting.

During the execution step 100, the first carrier 15A performs a gesture. The gesture includes, for example, a movement of an upper limb.

The description of the following stages will be made in the case, taken as an example, where the gesture is a movement of an arm of the first carrier 15A, the movement being carried out in a direction and ending in a position in which the arm is stretched in the direction, the index finger being stretched in the same direction. The information associated with this gesture is, for example, "show" or "watch".

The gesture performed by the first wearer 15A is observed by at least one second wearer 15B. The second carrier 15B understands that the first carrier 15B requests it to look in the direction in which the arm is stretched.

During the measurement step 110, at least one sensor 30A, 30B measures a value of the corresponding quantity.

For example, each sensor 30A, 30B periodically measures a value of the corresponding quantity with a predetermined period, and at least one value of each quantity is acquired during the execution step 100. The measurement period is, for example , between 50 milliseconds and 1 second.

In the example considered, at least a first sensor 30A measures values of an angle between an arm and a forearm of the first carrier 15A, indicating that an elbow of the first carrier 15A passes from a position in which the elbow is bent to a position in which the elbow is stretched, other first sensors 30A simultaneously measuring values of angles between different segments of the corresponding hand indicating that, among the fingers of the hand, only the index finger is stretched, and the index finger is stretched in the extension of the arm.

Other sensors 30A, 30B measure a direction in which the arm has moved, for example a "northwest" direction, or even a location of the first carrier 15A at the time when the first carrier 15A performs the gesture.

During the transmission step 120, each value measured during the execution of the gesture is transmitted, by the corresponding sensors 30A, 30B, to the centralization device 25 by radiofrequency communication.

For example, the first transmitter / receiver 80 transmits a first MV message to the centralization device 25. The first MV message includes the measured values.

For example, each first transmitter / receiver 80 transmits a first MV message periodically, with a predetermined period. The period of transmission of the first MV message is, for example, equal to the period of measurement of the values by each sensor 30A, 30B. Each first message MV then contains a value measured by each sensor 30A, 30B.

As a variant, the period of transmission of the first MV message is between half a second and five seconds.

The measured values are stored in memory 40.

After the transmission step 120, the recognition step 130 is implemented. During the recognition step 130, the gesture executed is recognized by the first computer 45 if the gesture is a gesture stored in memory 40.

During the recognition step 130, the first computer 45 compares, for example, each measured value with the associated identification values, for each gesture stored in the memory 40, with the same first sensor 30A.

If, for a gesture stored in the memory 40, the values measured by a first sensor 30A are included in the range of corresponding identification values for each of the first sensors 30A for which the gesture includes identification values, the gesture is recognized by the first computer 45. The recognition step 130 is then followed by the transfer step 140.

If no gesture is recognized, the transfer step 140 is not implemented.

During the transfer step 140, the centralization device 25 transfers the information associated with the gesture to the supervisor 20. For example, the first computer 45 generates a second message Mi intended for the terminal 50.

Alternatively, the centralization device 25 transfers the information to the recipient of the information. For example, the centralization device 25 transfers the information to each second carrier 15B if the information is intended for the entire team.

The second message Mi contains the information associated with the gesture recognized in the memory 40.

For example, the information associated with the gesture includes a location X of the wearer included in the first most recent MV message.

In optional addition, the information includes the direction in which at least part of the body of the first wearer 15A is oriented during the gesture.

In the example given, the information includes the orientation of the index of the first carrier 15A at the end of the gesture, and the information contained in the second message Mi is then "the first carrier 15A, at the location X , shows something in the northwest direction ".

Each second message Mi also contains the values of the physiological parameters measured for each carrier 15.

The transfer step 140 is followed by the communication step 150 and the broadcasting step 160.

During the communication step 150, the man / machine interface 65 transmits the information to the supervisor 20. For example, the man / machine interface 65 displays the information contained in the second message Mi in the form of a text displayed on the human-machine interface screen.

As a variant, the second computer 60 generates a graphic representation such as a map.

According to another variant, the second computer 60 generates, from the second message Mi, a third sound message containing the information transmitted by the second message Mi. The third message is then broadcast by the loudspeaker of the human interface / machine 65.

During the broadcasting step 160, the first computer 45 generates, from the information contained in the memory 40 at the end of the transfer step 140, a fourth audible message. The fourth message is then transmitted, by radio frequency communication, to the atrium of each second carrier 15B for which the information is intended.

For example, during broadcast step 160, the fourth message is sent only when the information is critical information.

The communication system 10 allows efficient transmission of information between the carriers 15 and the supervisor 20. The communication system 10 allows, in particular, the transmission of information during the action. The communication system 10 therefore allows better coordination of the actions of the various carriers 15 during an intervention in a dangerous environment.

In addition, the information transmitted by the carriers 15 is stored, which facilitates subsequent analysis. In addition, the information transmitted is not lost if porters 15 are unable to make a detailed report of their actions, for example due to serious injuries.

The communication system 10 automatically recognizes the gestures made by the carriers 15. However, in many cases, these gestures are conventional gestures forming a codified language and already used in the field by carriers 15. The communication system 15 does not assume therefore no learning or handling by the carriers 15, but only the execution of gestures already frequently used.

In addition, the transmission of information from the carriers 15 to the supervisor 20 takes place without specific actions being required from the carriers 15, since the gestures recognized by the communication system 10 are in any case used by the carriers 15 to communicate between them. The carriers 15 are therefore not decentralized by the need to communicate with the supervisor 20.

In addition, the communication system 10 does not require the use of additional equipment by the carriers 15, since the sensors 30 and, where appropriate, the first transmitter / receiver 80 are integrated in protective clothing of a type already used by carriers 15.

Thus, the use of the communication system 10 is very easy for the carriers 15. This is particularly advantageous in the case of intervention teams in dangerous environments such as the fire brigade or police teams, for which a communication system complex, cumbersome or involving specific actions of the carriers 15 would increase the risks for the carriers 15.

The communication system 10 also allows more reliable communication of information between the different carriers 15 or between the carriers and the supervisor 20, even in the event of reduced visibility or when the carriers 15 are in a noisy environment.

In addition, the communication system 10 is silent, since the gestures are not noisy and since it does not suppose that the carriers 15 speak. This allows the carriers 15 to carry out their mission discreetly.

In addition, the communication system 10 allows effective supervision of the state of the carriers 15, in particular their location and their physiological state. The supervision of the team of carriers 15 is therefore improved, and the security of the carriers 15 increased.
