Definitions
- the present invention is in the field of object and / or individual presence detection.
- One of the objectives of the present invention is to instrument a floor with one or more capacitive sensors capable of detecting the presence or absence of an object and / or an individual.
- the object of the present invention thus finds an advantageous application for detecting the fall of a senior in a room whose floor is instrumented with one or more capacitive sensors: the present invention is therefore particularly interesting for buildings, medical or not , dedicated to the elderly such as for example retirement homes.
- the document WO 2006/130081 proposes a method of detection of person at bedrise.
- the method proposed in this document is particularly adapted to the elderly and / or disabled.
- pressure sensors introduced into a polyurethane foam, are connected to a monitoring system that triggers an alarm when pressure is exerted on the sensors.
- WO 2009/050285 proposes a floor mat instrumented by a system composed of sensors. This system uses capacitance in relation to the deformation of an intermediate layer to detect the presence indifferently of a person or an object.
- the sensors introduced into this mat are not adapted to specifically detect the transfer of charges related to the presence of a person or an object.
- the incorporation of capacitive sensors in the floor of a room allows non-intrusive detection of the presence of people on the surface by measuring the variation of a physical quantity.
- capacitive sensors are sensors of choice for the detection of people. Indeed, the capacitive sensors function as capacitors and their capacity varies when an object or an individual approaches: this variation of the capacity makes it possible to determine the presence or not of an object or an individual near the sensor.
- the document FR 2 956 137 uses such capacitive sensors and proposes an instrumented floor for presence detection.
- the soil includes:
- this screed being insulating and covering the sensors.
- One of the objectives of the present invention is to improve the present situation described above by overcoming the disadvantages mentioned above.
- the object of the present invention relates to a capacitive sensor for detecting the presence of an object and / or an individual.
- the concept underlying the present invention is to adapt the geometry of the capacitive sensor; more specifically, the present invention provides a specific arrangement of the constituent electrodes of the sensor to best adapt to the physical properties, including dielectric properties, of the object and / or the individual whose presence must be detected.
- the capacitive sensor comprises at least three elongated electrodes which extend substantially in the same plane, and which are separated from each other over all or part of their length by a determined separation distance.
- This separation distance is substantially constant.
- this separation distance is of the order of a few millimeters.
- the electrodes are polarized independently of one another; this makes it possible to have independent measurements, which makes it possible to collect different information from one electrode to the other.
- the advantage of having at least two peripheral electrodes surrounding a central electrode is to limit the range of the electric field generated when the central electrode is polarized and surrounding peripheral electrodes are grounded.
- the measurement phases consisting of measuring the signal on the central electrode when one or more of the electrodes are polarized give information on the evolutions of the environment.
- the measurement phases consisting in measuring the signal on the other electrodes give information on the objects and / or persons near the sensor.
- the capacitive sensor comprises at least three electrodes including a central electrode having a determined radius of curvature and at least two peripheral electrodes positioned on either side of the central electrode.
- the axial distance between the axes of each electrode adjacent to each other is substantially between about 3 to 6 times this radius of curvature, this preferably when it is between the order from 0.05 to 1 millimeter.
- This ratio between the radius of curvature of the central electrode and the axial distances is one of the advantageous features of the present invention: this ratio makes it possible to obtain a very fine detection of the presence or absence of objects and / or individuals when they are near the sensor.
- the radius of curvature of the central electrode is preferably substantially between about 0.05 to 1 millimeter.
- the central electrode has a cross section of elliptical shape (crushed round shape).
- This elliptical shape is defined in particular by its radius of curvature.
- the radius of curvature is comparable to a radius.
- At least one electrode among the three electrodes of the capacitive sensor according to the present invention is mono-filament (that is to say is formed by a single wire).
- the three electrodes of the capacitive sensor according to the present invention are integrated in a protective sheath such as for example a cable and thus form a sheet of electrodes; this makes it possible to promote the holding in position of the electrodes between them and thus maintain a substantially constant separation distance between the electrodes.
- the capacitive sensor comprises at least four electrodes. In other words, an electrode has been added.
- this fourth electrode is also polarized independently of the other electrodes.
- this added electrode is mono filament.
- the advantage of adding such an electrode is to break the symmetry of the sensor. This increases the number of independent measurements and thus improves the accuracy of detection: the more independent measurements are, the less complex the estimation of the recognition of the measured situation.
- this so-called remote electrode is separated from each of the other electrodes by a distance that is substantially equal to at least ten times the separation distance.
- the advantage of this asymmetric geometry by adding at least one electrode remote from the other electrodes is to obtain variable ranges for using the measurement phases as independent information.
- the short-range measurement phases preferably allow to follow the environmental drifts related for example to the evolutions of the temperature and the hygrometry ambient.
- the medium-range measurement phases make it possible to limit the influence of the coupling to the ground.
- the long-range measurement phases (ie those where the measuring electrode is one of the two peripheral electrodes) make it possible to evaluate the coupling to the earth and thus to estimate the importance of the object or person detected.
- the capacitive sensor according to the present invention comprises an electronic processing unit which is configured to collect and process the electrical signal or signals emitted by each electrode when, for example, an object and / or an individual is in the vicinity of the capacitive sensor.
- the electronic processing unit is further configured to determine, as a function of the electrical signals emitted by each electrode, the presence or absence of an object and / or an individual near the capacitive sensor.
- this determination is carried out using a pre-established experimental database containing the information relating to the various possible scenarios: for example, falling person, passage of a domestic animal, etc.
- the capacitive sensor described above by its geometry and its structure, is particularly effective in terms of detection, since it allows the generation of precise and independent electrical signals in order to detect with a good precision the falls of people.
- this structure is particularly simple to deploy on the ground since it does not require an electrically insulating layer.
- the object of the present invention relates to a soil structure for detecting the presence of an object and / or an individual.
- soil in the sense of the present invention is meant any system which has a structure comprising in particular a yoke, and optionally a primer, a water-proofing barrier, a coating, a leveling layer, a layer of adhesive , and / or a coating layer.
- the ground structure comprises at least one capacitive sensor as described above.
- the instrumentation of the ground with at least one capacitive sensor as described above makes it possible to obtain a system that is particularly simple to install, such a floor being suitable for detecting the presence of an object and / or an individual.
- a soil instrumentation can be envisaged for inhabited premises which are being renovated or buildings under construction.
- the soil structure may have a leveling layer, which for example consists at least partially of mortar based on organic binder and / or mineral.
- the capacitive sensor is embedded in a protective sheath which can be polymeric, and which itself can be integrated into the leveling layer.
- this protective sheath is self-adhesive.
- This variant is particularly interesting for the implementation of the invention in the construction of a building or at least during the renovation of the floors. Such an installation is particularly robust.
- the floor structure may have a coating layer.
- coating layer can be understood here for example and without limitation a layer such as a parquet, a tile, a flexible coating such as knitted carpet, tufted, woven, flocked, in strips or slabs, a coating of needled soil, in strips or slabs, a homogeneous or heterogeneous polyvinyl chloride-based floor covering, a polyvinyl chloride based floor covering on a jute or polyester backing or on a polyester backing with polyvinyl chloride backing vinyl flooring, polyvinyl chloride-based floor covering, polyvinyl chloride-based floor covering with backing based on cork, an expanded polyvinyl chloride-based floor covering, a semi-flexible polyvinyl chloride-based slab or a cork chipboard with a polyvinyl chloride-based wear layer.
- a layer such as a parquet, a tile, a flexible coating such as knitted carpet, tufted, woven, flocked, in strips or slabs, a coating of needled soil
- the capacitive sensor is fixed by gluing, directly or indirectly, on at least a portion of the lower face of the coating layer.
- the soil structure may also have a leveling layer attached to the coating layer through a layer of glue.
- the capacitive sensor may be at least partially embedded in the adhesive layer.
- the soil structure may have a coating layer, which preferably consists at least partially in one of the materials mentioned above.
- the capacitive sensor can be integrated in the coating layer.
- the ground structure according to the present invention proposes several possible alternatives for ground instrumentation for detecting the presence of objects and / or individuals.
- the object of the present invention makes it possible, by varying the geometry of the electrodes, to detect different scenarios: falling person, intrusion of a person in a room or in a secured area, passing of a pet, etc.
- FIGS. 1a-4a-4b appended hereto illustrate various embodiment examples devoid of any limiting character and on which:
- Figs. 1a and 1b respectively show schematically a top view and a cross-sectional view of a capacitive sensor according to an advantageous embodiment of the present invention
- Figures 1a and 1d each show schematically a cross-sectional view of a capacitive sensor according to two other embodiments of the present invention
- Figure 1c shows schematically a top view of a capacitive sensor according to an advantageous embodiment of the present invention
- Figure 2 schematically shows a top view of a capacitive sensor according to another advantageous embodiment of the present invention
- Figures 3a to 3d each show a schematic sectional view of a soil structure according to an embodiment of the present invention.
- Figures 4a and 4b show tables of experimental values showing the influence of the distance between the electrodes in a capacitive sensor according to the present invention. Detailed description of various advantageous exemplary embodiments
- the concept underlying the present invention is to use the capacitive sensor technology and to vary several parameters so that these sensors are adapted to both their environment and to one of the scenarios that one seeks to detect, namely in the example described here the fall of people.
- various parameters that can be varied according to the present invention, include: the number of electrodes, their size, their geometry, and the relative disposition of these electrodes relative to each other. In varying these parameters, it is possible in particular to refrain from the presence of an electrically insulating layer as proposed in document FR 2 956 137.
- a "good" sensor 100 in the sense of the present application is a sensor for detecting the presence or absence of a person lying on the ground.
- the senor 100 according to the present invention must be sensitive to what is above the coating layer 230 of the soil without being hindered by its environment.
- the sensor 100 developed in the context of the present invention therefore comprises N electrodes that can be polarized independently of each other.
- N electrodes where N is a positive integer greater than or equal to 3 makes it possible to have N (N-1) / 2 independent measurements.
- the capacitive sensor 100 comprises three elongated electrodes E1, E2, and E3: the electrode E1 is a so-called central electrode which is surrounded by two electrodes E2 and E3 called devices.
- these three electrodes El, E2, and E3 extend longitudinally in a plane P (this plane defines for example the ground). As illustrated in FIG. 1a, the electrodes El, E2, and E3 extend in a rectilinear manner and are thus substantially parallel to one another over all or part of their length: each of the adjacent pairs of electrodes E2 / E1 and E3 / E1 is separated from a separation distance respectively d2 and d3 which is substantially constant over all or part of their length.
- the arrangement of electrodes El, E2, and E3 between them may have other geometries.
- the electrodes E1, E2, and E3 may each have zigzags thus forming a succession of "S", the important thing here being to have a separation distance that is substantially constant over all or part of the length of the electrodes.
- the electrodes El, E2, and E3 are provided so that they can be installed next to one another linearly; in the example described here, the electrodes El, E2, and E3, however, have elbows at the electronics box 110 to simplify the connection to the electronics box 110.
- the electrodes E1, E2, and E3 may also have bends to follow the contours of the geometry of the part (not shown here) provided that the separation distances d2 and d3 between the electrodes E1, E2, and E3 are substantially equal on their entire length (except of course at the elbows).
- the geometry that has been retained here to obtain a detection of falls is to select a central electrode El mono-filament whose rlrayon rl is substantially equal to 0.3 millimeter, and to separate the axis Al from the electrode E1 with the axes A2 and A3 respectively of the electrodes E2 and E3 of an axial distance d2 'and d3' substantially equal to 1.27 millimeters.
- the ratio between each axial distance d2 'and d3' and the radius of curvature r1 is substantially equal to approximately 4.2.
- This geometry makes it possible to obtain particularly satisfactory measurements when a person is in the vicinity of such a sensor 100.
- the electrodes may have other shapes: thus, as illustrated in Figures 1a and 1d, the central electrode El and / or the peripheral electrodes E2 and E3 may have a cross section having a shape elliptical (or a "patato ⁇ dale” form). In this case, we speak of "radius of curvature”. In any case, the ratios indicated above between axial distances and radius of curvature (or radius) remain unchanged.
- FIG. 4b shows the variations of the eigen capacities as a function of the inter-capacitances with a sensor as described above. As illustrated in this figure, the curve bundles are well differentiated from one another. These results thus highlight the difference between the measurement phases: the measurements obtained are independent of each other. This differentiation of the measurement phases makes it possible to envisage the discrimination of informative events of disturbing events.
- FIG. 4a represents, for its part, the variations of the eigen capacities as a function of the inter-capacitances with a sensor which does not respect the geometry proposed above (ratios and distances between the electrodes).
- the various curve beams are almost all identical.
- This figure thus shows that, when the distances between the electrodes are too large, the measurement phases produce a quasi-similar signal which implies a non-independence of the measurements, ie an impossibility to extract relevant information in the measurements.
- an electrode E1, E2 or E3 is too thin (that is to say has a radius of curvature r1 less than 0.05 millimeter), the immediate environment of the electrodes E1, E2 or E3 then a major impact on the electrical signal, this depends on the effects at longer distance. Indeed, the electric field decreases in 1 / d in the vicinity of an electrode.
- the electrodes E1, E2 and E3 have a radius of curvature having a value equivalent to half the average particle diameter of the coating layer in which it they are included: a mortar particle for example in the case where the sensor 100 is integrated in a leveling layer as shown in Figure 3a.
- each electrode El, E2, E3 behaves similarly (FIG. 4a).
- the coupling is important: this differentiates the electrodes having a strong coupling (the central electrode E1 for example ) electrodes having a lower coupling (the peripheral electrodes E2 and E3 for example). This geometry thus makes it possible to have independent results (FIG. 4b).
- the capacitive sensor 100 comprises an electronic unit 110 which is configured to collect and process the independent electrical signal or signals emitted by each electrode E1, E2 and E3 when for example an object and / or an individual is in the vicinity of the capacitive sensor 100.
- This housing 110 is further configured to determine, as a function of the electrical signals emitted by each electrode E1, E2, and E3 and of a pre-established database, the presence or no of an object and / or an individual near the capacitive sensor 100.
- a second advantageous exemplary embodiment illustrated in FIG. 2 comprises all the characteristics described above for the first exemplary embodiment and furthermore provides the addition of a fourth electrode E4 which is remote from the electrode E3 of a distance of distance d4 substantially equal to at least ten times the separation distance d2 or d3.
- this fourth electrode E4 makes it possible to have variable ranges making it possible to use the measurement phases as independent information and thus to get rid of, for example, environmental drifts.
- This example of a sensor 100 having such an asymmetrical geometry makes it possible to obtain a capacitive detection whose measured coefficients are differentiated on the detection height and sensitive to the environment of the object or the individual whose presence must be detected or not. .
- the sensor 100 according to the two exemplary embodiments described here and illustrated in FIGS. 1a-1b and 2 is therefore particularly efficient. It can also be easily integrated in a floor structure 200, this in particular because it does not require the presence of electrically insulating layer.
- each of these structures comprising at least one sensor 100 according to the first embodiment of FIGS. 1a and 1b (see in particular FIGS. 3a to 3d).
- FIGS. 3a to 3d see in particular FIGS. 3a to 3d.
- any other type of sensor 100 according to the present invention can be envisaged here (especially those of Figure 2: not shown here).
- FIG. 3a provides for the incorporation of sensors 100 into a leveling layer 210.
- the sensors 100 are embedded in a sheath, possibly polymeric, which can be perforated and self-adhesive. This sheath also ensures that the geometry and the spacing between the electrodes El, E2 and E3 of each sensor 100 are maintained in position.
- the soil instrumentation may for example be carried out as follows: laying the yoke 240, applying a layer of primer on the yoke 240 installing capacitive sensors 100 on the primer layer, casting a leveling layer 210 on the sensors 100, applying an adhesive layer 220 and a coating layer 230 to the instrumented dry patching 210 with the sensors 100.
- an instrumented floor having such a structure 200 with the capacitive sensors 100 can effectively detect people near the ground without the need to put an additional insulating layer.
- FIGS. 3b and 3c provide for ground instrumentation with sensors 100 placed directly or indirectly on the leveling layer 210.
- the ground instrumentation is carried out as follows: the capacitive sensors 100 are added between self-adhesive strips forming a layer of adhesive 220 placed on the leveling layer 210.
- FIG. 3c differs from the example of FIG. 3b in that the capacitive sensors 100 are fixed by bonding directly on a portion of the lower face of the coating layer 230.
- the sensors 100 are directly introduced into the coating layer 230.
- the previous steps of the installation are repeated, having previously fabricated an instrumented coating layer 230. for example by weaving the sensors 100 with the coating layer 230.
- the geometry of the electrodes El, E2 and E3 as provided in the context of the present invention is particularly advantageous and allows the design of a capacitive sensor 100 ensuring a detection of fine and precise presence of people and / or objects that are located near said sensor.
- the sensors 100 thus obtained can easily be used to instrument a floor for an application for example in medical buildings and / or retirement homes, the floor structure 200 does not require here the presence of an electrically insulating layer as it is the case in the state of the art.
