Description

COMMUNICATION SYSTEM

The present invention relates to a communication system. The invention relates, in particular, to a communication system converting energy generated by an exposed means to the mechanical energy of a rotating object or an object for use with a rotating object.

Incorporating electronic devices into a rotating object or an object for use with a rotating object offers many practical advantages. The electronic devices may include sensors and other components for obtaining information regarding various physical parameters of a rotating object or an object for use with a rotating object, such as temperature, pressure, number of revolutions , speed, number of rotations versus speed, temperature versus speed and other physical and functional parameters as well as manufacturing information such as name of manufacturer, place of manufacture, date of manufacturing, etc. Such performance information can become useful in monitoring and warning systems, and can even potentially be used with feedback systems to regulate levels appropriately.

Integrated electronic systems are conventionally powered by various energy production techniques and systems, for example complex mechanical systems such as a pump assembly or an electromagnetic generator installed in an interior tire cavity, a source of energy. piezoelectric blade energy, a non-rechargeable battery, or a radio frequency (RF) beam energy source.

Non-rechargeable batteries are commonly used, for example for a SSPP (Tyre Pressure Monitoring System), this in itself causing inconvenience for the user since correct operation of the electronic system depends on periodic replacement of the battery. battery. On the other hand, conventional batteries often contain heavy metals which are harmful to the environment and pose problems from a disposal point of view, especially when used in very large quantities. Additionally, batteries tend to deplete relatively quickly when powering electronic applications characterized by high levels of functional complexity. Battery drain is particularly common in electronic systems that transmit information over relatively large distances, for example from locations on truck wheels to a receiver in the truck cabin.

With an RF beam power source, the energy that is emitted from an interrogation antenna is harvested to power the electronic systems, which often must be very specialized ultra-low power electronic systems limited to a few microwatts . Interrogation antennas employed with beam-fed electronic systems must, generally, be placed in relatively close proximity due to the limited transmission range.

Document WO03/095244 discloses a system for producing electrical energy from the mechanical energy of a rotating tire comprising a piezoelectric structure and an energy storage device installed inside a tire for generating an electrical charge as the wheel moves along a ground surface.

Document US2005/0285728 discloses a system and a corresponding method for the production of electrical energy from the mechanical energy of a rotating tire and relates to a piezoelectric energy production device associated with a recovery and power conditioning, the system can be used to power various electronic systems integrated into a tire or wheel assembly.

A constant objective in this field is to increase the quantity of energy recovered independently of rotation speed and until the end of the product's life.

This structure makes it possible to increase the quantity of energy recovered independently of the rotation speed of the rotating object or the object to be used with the rotating object, and this until the end of the product's life.

By setting this predetermined distance of at least one component of the plurality of system components to a value at most equal to 1/4 of the circumferential length of the rotating object, it is possible to increase the amount of energy harvested independently of a rotation speed of the rotating object or the object to be used with the rotating object, and this until the end of the life of the product.

The predetermined distance of at least one component of the plurality of system components is preferably at most 1/8 of the circumferential length of the rotating object, more preferably at most 1/10 of the length circumferential length of the rotating object, and even more preferably at most equal to 1/12 of the circumferential length of the rotating object.

In another preferred embodiment, at least one of the plurality of system components is incorporated into the film layer.

With this structure, since the film layer can reduce a risk of destruction of the system components incorporated in the film layer, it is possible to increase the amount of energy recovered independently of a rotation speed, and this until the end of the product's life.

Note that each system component is represented by a symbol to indicate its location in a system and not its specific form.

A communication system 3 according to a first embodiment of the present invention will be described with reference to the and 2.

There is a schematic sectional view of an object for use with a rotating object with an incorporated communication system according to the first embodiment of the present invention. There is a schematic view of a communication system extracted from an object for use with a rotating object according to a first embodiment of the present invention.

Communication system 3 is a system for an object 1 for use with a rotating object (not shown). In this first embodiment, object 1 is a conveyor belt and the rotating object (not illustrated) is therefore a plurality of rollers. The object 1 comprises two layers of carcass 11 extending in a circumferential direction of the rotating object, imparting linear resistance and shape to the object 1. The object 1 also comprises a coating layer 12 completely covering the carcass layers 11. The communication system 3 is incorporated in the covering layer 12 under the carcass layers 11. An axial width "wc" of the carcass layers 11 is less than an axial width of the object 1, a width axial width “wf” of the communication system 3 is less than the axial width “wc” of the carcass layers 11.

As illustrated on the and 2, the communication system 3 comprises at least one layer extending along a circumferential direction of the object 1 for use with the rotating object (not shown). The at least one layer is a film layer made of an elastomeric composition. The communication system 3 comprises at least two layers of film. A thickness of the film layer is between 150 μm and 1800 μm. In this first embodiment, the communication system 3 comprises 3 layers of film, a first layer of film 31, a second layer of film 32 and a third layer of film 33, and the thickness t1, t2 and t3 of each of film layers 31, 32 and 33 is 400 μm.

As illustrated on the , the communication system 3 comprises a plurality of system components comprising at least a plurality of data processing units 5, a plurality of communication units 6 and a plurality of energy units 4. The plurality of energy units 4 comprises at least a plurality of energy recovery parts 41, also employed as a plurality of capture units capturing a physical state of the rotating object or the object to be used with the rotating object, and a plurality of storage parts 42. At least one component of the plurality of system components is embedded in the film layer. The communication system 3 includes three film layers 31, 32 and 33, and each of the three film layers 31, 32 and 33 includes different system components among the film layers. In this first embodiment, the energy units 4 also include a plurality of energy management parts 43 and a plurality of rectification parts 44. The first film layer 31 includes the plurality of energy recovery parts energy 41 incorporated, the second film layer 32 comprises the plurality of storage parts 42, the plurality of energy management parts 43 and the plurality of rectification parts 44 incorporated, and the third film layer 33 comprises the plurality of data processing units 5 and the plurality of communication units 6 incorporated.

As illustrated on the , at least one component of the plurality of system components is distanced in the circumferential direction by the predetermined distance “P”, this predetermined distance “P” being at most equal to 1/4 of a circumferential length of the rotating object (not shown).

When object 1 comes into contact with the rotating object (not shown) or is separated from the rotating object (not shown), object 1 is deformed so that it takes on or loses a shape corresponding to that of the rotating object (not shown). In response to such deformation, each energy recovery part 41 of the energy units 4 generates electrical pulses. These generated pulses would be shaped by the rectification parts 44 of the energy units 4 then sent to the energy management parts 43 of the energy units 4.

The energy management parts 43 of the energy units 4 observe the state of the entire communication system 3 in terms of raw signal acquisition frequency, communication distance and time interval between communications which may vary depending on the use, and then provide the shaped pulse to the data processing units 5 for analysis of the signal in terms of time interval, intensity and profile which would correspond to a physical state of the object 1 such as (rotational) speed, load, wear, etc. Simultaneously, the energy management parts 43 of the energy units 4 also supply the shaped pulse to the storage part 42 of the energy units 4 so that energy is always available for the communication system 3 even in the event of a temporary insufficiency in energy production, or provide the required energy to the communication system 3 from the storage part 42 of the energy units 4.

The analyzed physical state of the object 1 and/or the data processed by means of the data processing units 5 would be transmitted via the communication units 6, instantly and wirelessly, for example to a dashboard maintenance or a cloud.

The energy recovery part 41 of the energy units 4 is a unit for recovering mechanical energy, for example an electromagnetic unit, an electrostatic unit or a piezoelectric unit and, preferably, the piezoelectric unit comprises a beam-type piezoelectric structure or foil system integrated or linked to structures to capture mechanical energy when the system is in motion.

A piezoelectric material intended to be used in the energy recovery part 41 of the energy units 4 is chosen from the group consisting of single crystals such as quartz type, LiNbO3 (lithium niobate), LiTaO3 (lithium tantalate) , PMN-PT or PZN-PT, ceramics such as PbTiO3 (lead titanate), Pb(ZrxTi1-x)O3 or PZT (lead titano-zirconate), BiFeO3 (bismuth ferrite), BaTiO3 (barium titanate) or (K0.5Na0.5)NbO3 (potassium and sodium niobate), the last 3 ceramics being preferable due to the directive of the European Parliament and of the Council relating to the limitation of use six dangerous substances including lead, composites consisting of two phases, a piezoelectric phase (ceramic or single crystal) and a non-piezoelectric phase (polymer), and polymers such as PVDF (poly(vinylidene fluoride)) or certain of its copolymers such as P(VDF-TrFE) (poly(vinylidene fluoride-trifluoroethylene)).

A material constituting the layer, in particular the film layer, is an elastomeric composition such as a composition comprising thermoplastic elastomers such as polyacrylic acids, acrylonitrile-butadiene-styrene, poly(methyl methacrylate), polyamides such such as nylon, polylactic acid, polybenzimidazole, polycarbonate, polyethersulfone, polyoxymethylene, polyetheretherketone, polyetherimide, polyethylene, poly(phenylene oxide), poly(phenylene sulfide), polypropylene, polystyrene, poly(vinyl chloride), poly(vinylidene fluoride) or polytetrafluoroethylene.

The storage part 42 of the energy units 4 is a unit allowing numerous rapid charge/discharge cycles, such as a supercapacitor (also called ultracapacitor) of any type, electrostatic double-layer capacitors, electrochemical pseudocapacitors or hybrid capacitors such as a lithium ion capacitor.

Each component of the communications system is connected through means known in the field of electrical circuits and/or interconnection, for example printed wiring, a printed circuit board, metallic wiring or elastomeric wiring. An electronic connection can be applied by screen printing or 3D printing.

Since the communication system 3 has a plurality of system components including at least a plurality of data processing units 5, a plurality of communication units 6 and a plurality of energy units 4, the plurality of energy units 4 comprising at least a plurality of energy harvesting parts 41, also employed as a plurality of capture units capturing a physical state of the rotating object or the object to be used with the object rotary, and a plurality of storage parts 42, and comprises at least one layer extending along a circumferential direction of the object 1 to be used with the rotating object, and that the at least one component of the plurality of system components is placed in the at least one layer, the communication system 3 can be easily installed, either attached to or incorporated into the object to be used with the rotating object, and it is therefore possible to increase flexibility of installation of the communication system 3.

Since the at least one component of the plurality of system components is placed in the at least one layer with a predetermined distance "P" between identical components in adjacent circumferential positions along the circumferential direction of the object 1 to be used with the rotating object, the communication system 3 can recover a sufficient amount of energy regularly and continuously with the rotation of the object 1 to be used with the rotating object, and it is therefore possible to increase the quantity of energy recovered independently of a rotation speed of the object 1 to be used with the rotating object, and this until the end of the life of the product.

Since the plurality of energy harvesting parts 41 of the plurality of energy units 4 are also employed as a plurality of capture units capturing a physical state of the rotating object or the object to be used with the rotating object, a succession of pulses from the plurality of energy harvesting parts 41 of the plurality of energy units 4 is analyzed in terms of time interval, intensity and profile by means of the plurality of data processing units 5 indicating various physical states of the object 1 to be used with the rotating object such as rotation speed, load, shock, wear or contact with an obstacle, and it is therefore possible to increase the efficiency of the communication system.

Since the at least one layer is a film layer made of an elastomeric composition, and a thickness of the film layer is between 150 μm and 1800 μm, it is possible to increase the amount of energy recovered independently of a rotation speed of the object 1 to be used with the rotating object, and this until the end of the life of the product, since the elastomer composition can be compatible with a material constituting the object 1 to be used with the rotating object, this ensuring good deformability for adequate operation while maintaining a certain stiffness in order to be able to transmit the deformation to the plurality of energy units 4.

If the thickness of the film layer is less than 150 μm, there is a risk that the thickness cannot accommodate some of the system components, which may lead to the destruction of the system components. If the thickness of the film layer is greater than 1800 μm, there is a risk that the film layer may not deform adequately, which may reduce the amount of energy harvested. By setting this thickness of the film layer between 150 μm and 1800 μm, it is possible to increase the amount of energy recovered independently of a rotation speed of the rotating object or the object to be used with the object rotary, and this until the end of the product's life.

The thickness of the film layer is preferably between 180 μm and 1600 μm, more preferably between 200 μm and 1500 μm.

Since the predetermined distance "P" of at least one component of the plurality of system components is at most 1/4 of a circumferential length of the rotating object, it is possible to increase the amount of energy recovered independently of a rotation speed of the object 1 to be used with the rotating object, and this until the end of the life of the product.

If the predetermined distance "P" of at least one component of the plurality of system components is greater than 1/4 of the circumferential length of the rotating object, there is a risk that energy harvesting of the communication system 3 becomes insufficient due to a reduced probability of deformation of the object 1 to be used with the rotating object. By setting this predetermined distance "P" of at least one component of the plurality of system components to a value at most equal to 1/4 of the circumferential length of the rotating object, it is possible to increase the amount of energy recovered independently of the rotation speed of the object to be used with the rotating object, and this until the end of the product's life.

The predetermined distance "P" of at least one component of the plurality of system components is preferably at most equal to 1/8 of the circumferential length of the rotating object, more preferably at most equal to 1/10 of the circumferential length of the rotating object, and even more preferably at most equal to 1/12 of the circumferential length of the rotating object.

Since at least one component of the plurality of system components is incorporated in the film layer, it is possible to increase the amount of energy harvested independently of a rotation speed until the end of the life of the product, since the film layer can reduce a risk of destruction of the system components incorporated in the film layer.

Since the communication system 3 includes at least two layers of film, the possibility of increasing the installation flexibility of system components in the communication system 3 is greater.

Since the communication system 3 comprises three film layers 31, 32 and 33, and each of the three film layers 31, 32 and 33 comprises different system components among the film layers, the possibility of increasing flexibility installation of system components in the communication system while also increasing the manufacturing efficiency of the film layers is even greater.

Each of the film layers 31, 32 and 33 can be divided into several independent segments in terms of energy harvesting and signal capture. This fragmentation allows better energy recovery and autonomous operation since even if one segment is damaged, the other segments can continue to operate. Fragmentation in terms of signal capture also allows mapping of the entire surface of object 1; we can then access several pieces of information such as the state of object 1, the location of shocks and/or damage on object 1.

The axial width “wf” of the communication system 3 may be similar to the axial width “wc” of the carcass layer 11. The axial width “wf” of the communication system 3 may vary from one layer to another.
