Description

Title of the invention: Method and device for verifying the conformity of the orientation of objects placed in a stack

[0001] The invention relates to a method and a device for verifying the conformity of the direction in which objects are placed in a stack.

[0002] The field of the invention relates to the logistical management of connected or connectable goods.

[0003] Systems are known in which vertically spaced radio frequency antennas make it possible to detect radio frequency emitting devices, such as RFID tags, objects in the stack.

[0004] One of the problems of these systems is to determine in a reliable and automated way the direction of placement of objects in the stack.

[0005] Indeed, the wrong direction of placement of an object in the stack wastes time in processing the stack of objects, when this direction of placement must obey rules.

[0006] An objective of the invention is to obtain a method and a device for verifying the conformity of the direction of placement of objects placed in a stack, which makes it possible to solve the problem mentioned above, by making it possible to refine the information obtained from the identifiers of the objects.

[0007] To this end, a first object of the invention is a method for verifying the conformity of the orientation of objects placed vertically one on top of the other to constitute a vertical stack of objects, each object in the vertical stack carrying at least one device for emitting an object identifier, which is located closer to an upper side of the object in a vertical direction in an upward orientation or closer to a lower side of the object in a vertical direction in a downward orientation, the identifiers being different from each other, the method comprising a step in which the vertical stack of objects is brought in front of an identifier detection device, comprising at least one set of several radio frequency antennas, which have positions spaced at least vertically apart from each other by at least a determined antenna spacing,characterized in that the method comprises the following other steps, carried out by a computer: determination of an estimated height of each identifier, having been detected by the detection device, along the vertical direction, calculation of distances between the estimated heights having been classified in ascending or descending order, , querying at least one database, in which is pre-recorded, in association with each identifier, a height indication between the top side of the object bearing the identifier and the bottom side of the object bearing the identifier; comparison of each distance to a prescribed first theoretical height, in the case where the computer has determined that at least one of the distances, called the first distance, calculated between a first of the estimated heights corresponding to a first of the identifiers and a second of the estimated heights, which corresponds to a second of the identifiers and which is located above the first height following this first height in ascending order, is less than or equal to the first theoretical height; provision, on a physical output, of initial information indicating that the objects are not all placed in the same orientation in the vertical stack, In the event that the calculator has determined that the first distance is greater than the first theoretical height, the first distance is compared to a second theoretical height, which is a function of the height indications associated with the first and second identifiers. In the event that the computer has determined that the first distance is greater than the second theoretical height, the physical output provides the first piece of information indicating that the objects are not all placed in the same orientation in the vertical stack. in the case where the computer has determined that the first distance is less than or equal to the second theoretical height, provision, on a physical output, of a second piece of information indicating that the objects are all placed in the same direction of placement in the vertical stack.

[0008] Thanks to the invention, a verification of the orientation of the objects placed in the stack is automatically and reliably provided to the user before any further processing of the stack. This makes it possible to verify the conformity of a stack of objects, and in particular the orientation of the various objects, thus avoiding the loss of cycle time for processing the stack by restoring the stack before processing, or allowing the stack state to be updated before processing.

[0046] Examples of methods for verifying the correct orientation of objects according to embodiments of the invention are described in more detail below with reference to Figures IA to 17. Examples of devices 1000 for verifying the correct orientation of objects according to embodiments of the invention are described below. The verification device 1000 is configured to implement the verification method.

[0047] As illustrated by way of example in [Fig.2], the objects (or material goods) 201, 202, 203, 204 are placed vertically one on top of the other to form a vertical stack 200 of these objects 201, 202, 203, 204. The number M of objects 201, 202, 203, 204 in the stack 200 is a prime natural number greater than or equal to 2 or 3. Of course, the invention would also work with M=1.

[0048] Each object 201, 202, 203, 204 is fitted with one (or more) respective device 2010, 2020, 2030, 2040 for issuing an ID identifier of the object 201, 202, 203, 204. Each respective ID identifier is unique and serves to identify the object 201, 202, 203, 204 that bears it. The respective ID identifiers are different from one another. The index i is used to designate the respective identifier ID; and the respective object 201, 202, 203, 204 identified by this respective identifier ID;. The index i is a second natural number ranging from 1 to M. The same number (one or more) of devices) 2010, 2020, 2030, 2040 can be provided for the respective issuance of the identifier ID; on each object 201, 202, 203, 204. Each identifier ID; can be a string of characters, or other.

[0049] On each object 201, 202, 203, 204 of the vertical stack 200, the device 2010, 2020, 2030, 2040 for emitting the identifier ID; of the object 201, 202, 203, 204 is located closer to an upper side PSUP of the object 201, 202, 203, 204 in the vertical direction Z in the case where the device 2010, 2020, 2030, 2040 for emitting the identifier ID; is placed with its orientation facing upwards in the vertical stack 200 or is located closer to a lower side of the PINF of the object 201, 202, 203, 204 along the vertical Z direction in the case where the ID emitting device 2010, 2020, 2030, 2040 is placed with its orientation facing downwards. The vertical Z direction is oriented from bottom to top.

[0050] For example, as shown in [Fig. 2], each of the objects 201, 202, 203, 204 comprises a wheel R on which is mounted a tire P (which may be inflated or deflated), constituting an assembled unit (R, P). The diameters of the tires P are arranged horizontally in the stack 200. The tires P rotate about a central geometric axis 210, which is vertical in the stack 200. The central geometric axis 210 is parallel to the vertical direction Z. Each object 201, 202, 203, 204 could consist solely of a tire P, for example, in a deflated state, without a wheel R.

[0051] In Figures 11, 12, 16, and 17, the verification device 1000 includes a device 3 for detecting IDs. The detection device 3 includes a set 31 of N radio frequency antennas Aj, or a first set 31 of N radio frequency antennas Aj and a second set 32 ​​of N other radio frequency antennas Aj, as shown. The index j designates the radio frequency antenna Aj of each set 31 or 32. The index j is a fourth natural number from 1 to N.

[0052] The successive radio frequency antennas Aj and Aj+i have respectively height positions PAj and PAj+i spaced at least vertically apart from each other by at least a determined antenna spacing D, non-zero, along the vertical direction Z.

[0053] According to one embodiment of the invention, the determined spacing D of antennas can be uniform between the antennas Aj.

[0054] According to another embodiment of the invention, the determined antenna spacing D may not be uniform between the antennas Aj and may have a non-zero minimum spacing value.

[0055] According to one embodiment of the invention, each object 201, 202, 203, 204 has a height INDH between the upper side PSUP of the object 201, 202, 203, 204 bearing the identifier ID; of this object 201, 202, 203, 204 and the lower side PINF of the object 201, 202, 203, 204 bearing the identifier ID; of this object 201, 202, 203, 204. According to one embodiment of the invention, the heights INDH of the objects 201, 202, 203, 204 may be identical. According to another embodiment of the invention, several (or all) of the INDH heights of objects 201, 202, 203, 204 may be different from one another. According to one embodiment of the invention, each INDH height of object 201, 202, 203, 204 may be greater than or equal to a prescribed minimum height value.

[0056] According to one embodiment of the invention, the determined antenna spacing D is less than each height INDH of objects 201, 202, 203, 204 or than the minimum prescribed height value.

[0057] According to one embodiment of the invention, the determined spacing D of the antennas is less than or equal to half the height INDH of each object 201, 202, 203, 204, or half the minimum prescribed height. Thus, at least two of the N radio frequency antennas Aj are located horizontally opposite each object 201, 202, 203, 204.

[0058] Of course, more than two sets 31 of N radio frequency antennas Aj could be provided. The sets 31, 32 of N radio frequency antennas Aj can be distributed around the axis 212 of rotation, described below. Each set 31 or 32 is designated collectively below by the N radio frequency antennas Aj. N is a third natural number greater than or equal to 4, or greater than or equal to 8, or greater than or equal to 10, or greater than or equal to 16. As shown in Figures 11, 12, 16, and 17, in each set 31 and / or 32, the N radio frequency antennas Aj are, for example, arranged one above the other. Of course, in other embodiments not shown, the N radio frequency antennas Aj could be horizontally offset from each other in each set 31 and / or 32.

[0059] In [Fig. 1 A], the method for verifying the conformity of the orientation of objects 201, 202, 203, 204 includes a step El in which the vertical stack 200 of objects 201, 202, 203, 204 is brought in front of the IDi identifier detection device 3. The device 3 detects the IDi identifiers of the objects 201, 202, 203, 204 in the vertical stack 200. In one embodiment, the IDi identifier detection device 3 can, in particular, determine the order in which the objects 201, 202, 203, 204 are arranged along the vertical direction Z in the vertical stack 200.

[0060] The method for verifying the conformity of the direction of placement of objects 201, 202, 203, 204 includes the following other steps, carried out by a computer 4.

[0061] The calculator 4 is configured to determine, during the second step E2, an estimated height h(ID) of each identifier ID detected by the detection device 3, along the vertical direction Z, i.e., the vertical position of each identifier ID of each object 201, 202, 203, 204 along the Z direction. Embodiments of calculating this estimated height h(ID) of each identifier ID detected by the detection device 3 will be described later. Of course, this estimated height h(ID) of each identifier ID detected by the detection device 3 could be calculated by the calculator 4 in a way other than these embodiments.

[0062] The calculator 4 is configured to classify during the third step E3 the estimated heights h(ID;) and h(IDi+i) in ascending or descending order along the vertical direction Z.

[0063] For example, figures 2, 3, 4, 5, 6, 8 and 12 consider that the devices 2010, 2020, 2030, 2040 for the emission respectively of the identifiers ID, h ID;, IDi+i, IDi+2 of the objects 201, 202, 203, 204 are successively one on top of the other along the vertical direction Z, for the index i going from 2 to M-2.

[0064] The calculator 4 is configured to calculate, during the third step E3, distances d(IDi+i, ID;) between the estimated heights h(ID;) and h(IDi+i) that have been sorted in ascending or descending order along the vertical direction Z, for i ranging from 1 to Ml. The calculator therefore calculates, during the third step E3, each distance d(IDi+i, ID;) as being equal to the absolute value of the difference between the successive estimated heights h(ID;) and h(IDi+i) in ascending or descending order.

[0065] We therefore have d(IDi+1, ID;) = | h(IDi+1) - h(ID;) | .

[0066] As shown in [Fig.7], the device 1000 includes a database B1, in which is pre-recorded in association with each identifier ID; , an INDH height indication between the upper side PSUP of the object bearing the identifier ID; and the lower side PINF of the object bearing the identifier ID;, for the index i ranging from 1 to M.

[0067] The calculator 4 is configured to query, during the fourth step E4, the database B1 by the ID identifiers; to obtain the INDH height indications associated therewith.

[0068] The calculator 4 is configured to compare during the fifth step E5 each distance d(IDi+i, ID;) to a first prescribed theoretical height H1TH.

[0069] The computer 4 is configured to provide, during the sixth step E6 on the physical output 5 of the conformity verification device 1000, a first INFNCONF information indicating that objects 201, 202, 203, 204 are not all placed in the same orientation in the vertical stack 200, in the case where the computer 4 has determined during the fifth step E5 that at least one of the distances d(IDi+i, ID;), called the first distance (or first difference), calculated between a first h(ID;) of the estimated heights corresponding to a first ID; of the identifiers and a second h(IDi+i) of the estimated heights, which corresponds to a second IDi+i of the identifiers and which is located above the first height h(ID;) following this first height h(ID;) in ascending order, is less than or equal to the first theoretical height H1TH. We therefore have d(IDi+i, ID;) = | h(IDi+i) - h(ID;) | .

[0070] The calculator 4 is configured to compare during the seventh step E7 the first distance d(IDi+i, ID;) to a second theoretical height H2THii+i, which is a function of the height indications INDH associated with the first identifier ID; and the second identifier IDi+i, in the case where the calculator 4 has determined during the fifth step E5 that the first distance d(IDi+i, ID;) is greater than the first theoretical height H1TH.

[0071] The computer 4 is configured to provide, during the eighth step E8, on the physical output 5, the first INFNCONF information indicating that the objects 201, 202, 203, 204 are not all placed in the same orientation in the vertical stack 200, in the case where the computer 4 has determined during the seventh step E7 that the first distance d(IDi+i, ID;) is greater than the second theoretical height H2THii+i

[0072] The computer 4 is configured to provide during the ninth step E9, on the physical output 5, a second INFCONF information indicating that the objects 201, 202, 203, 204 are all placed in the same direction of placement in the vertical stack 200, in the case where the computer 4 has determined during the seventh step E7 that the first distance d(IDi+i, ID;) is less than or equal to the second theoretical height H2THii+1.

[0073] This allows the user to verify that all objects 201, 202, 203, 204 in stack 200 conform to a single orientation. This orientation can be either upwards or downwards.

[0074] The above invention makes it possible in particular to cover the different examples in Figures 3, 4, 5, 6, 8A and 8B, which will be described in more detail below.

[0075] In particular, [Fig. 8B] corresponds to a case where the first identifier ID; is associated in database B1 with the PRB prescription for downward insertion, where the third identifier IDm is associated in database B1 with the PRB prescription for downward insertion, where the second identifier IDi+i is associated in database B1 with the PRH prescription for upward insertion, and where the fourth The identifier IDi+2 is associated in the B1 database with the PRH prescription for installation direction upwards.

[0076] According to one embodiment, the first theoretical height H1TH is a first linear or affine function of the determined antenna spacing D according to the following first formula: H1TH= a*D+b , where a is a first prescribed real coefficient, b is a second prescribed real coefficient and * denotes multiplication.

[0077] For example, a < 1. For example, a = 1 and b = 0. In another example, a = 0.5 and b = 0. For example, HITH = 5 cm. Of course, the first coefficient a and the second coefficient b can have values ​​other than these examples. Of course, HITH can have values ​​other than these examples.

[0078] According to another embodiment, the first theoretical height HITH is a function of the material thickness of the tire casing P of the object 201, 202, 203, 204. This material thickness of the tire casing P may differ depending on the type of vehicle on which the tire casing P will be mounted. For example, in stack 200, all the tire casings P of objects 201, 202, 203, 204 may have the same type of vehicle on which these tire casings P will be mounted. For example, the material thickness of the tire casing P for a passenger car tire is less than the material thickness of the tire casing P for a heavy-duty vehicle tire. In this case, the first theoretical height HITH is an increasing function of the material thickness of the tire casing P.Thus, the first theoretical height (HITH) for a passenger vehicle tire is smaller than for the tire casing (P) for a heavy vehicle tire.

[0079] According to one embodiment, the height INDH associated with the first identifier ID; is equal to the height INDH associated with the second identifier IDi+i. The second theoretical height H2THi i+i is a second linear or affine function of the height INDH associated with the first identifier ID; and the second identifier IDi+i according to the following second formula: H2THii+1 = c*INDH, where c is a third prescribed real coefficient, non-zero and * denotes multiplication.

[0080] For example, c > 1. For example, c > 1.2. For example, c = 1.4. Of course, the third coefficient c can have values ​​other than these examples.

[0081] According to another embodiment, the height indication INDH; associated with the first identifier ID; is different from the height indication INDHi+i associated with the second identifier IDi+i. The second theoretical height H2TH; i+i is a third linear or affine function of the indication INDH; of height associated with the first identifier ID; and of the indication INDHi+i of height associated with the second identifier IDi+i according to the following third formula: H2THi>i+1 = k*(INDHi + INDHi+1), where k is a prescribed, non-zero fourth real coefficient and * denotes multiplication.

[0082] For example, k > 0.7. For example, k = 0.9. Of course, the fourth coefficient k can have values ​​other than these examples.

[0083] According to one embodiment, in [Fig.1B], the process includes the following other steps, which are carried out by the computer 4, in the case where the physical output 5 has the second information INFCONF indicating that the objects 201, 202, 203, 204 are all placed in the same direction of placement in the vertical stack 200 according to step E9.

[0084] The calculator 4 is configured to calculate during the tenth step E10 a vertical interval ME between the lowest of the estimated heights h(ID;) (i.e. corresponding to the identifier located lowest along the upward vertical direction Z, which in the example of [Fig.2] is the height h(ID; 1) corresponding to the identifier ID4) and a reference point REF of an upper surface 211 of support of the vertical stack 200 of the objects 201, 202, 203, 204.

[0085] The calculator 4 is configured to determine during the eleventh step El 1 the smallest mini(d(IDi+i, ID;)) of the distances d(IDi+i, ID;) on the index i going from 1 to Ml.

[0086] The calculator 4 is configured to compare during the eleventh step El 1 the vertical interval ME to the smallest mini(d(IDi+i, ID;)) of the distances d(IDi+i, ID;).

[0087] The computer 4 is configured to provide, during the twelfth step E12, on the physical output 5 of the conformity verification device 1000, a third INFB placement direction information downwards, indicating that the devices 2010, 2020, 2030, 2040 for emitting identifiers ID; _ b ID;, IDi+i, IDi+2 of objects 201, 202, 203, 204 are all located, in the vertical stack 200, closer to their lower side PINF than to their upper side PSUP along the vertical direction Z, in the first case where the computer 4 has determined during the eleventh step Eli that the vertical interval ME is less than the smallest mmi(d(IDi+i, ID;)) of the distances d(IDi+1, ID;).

[0088] This case is represented by way of non-limiting example in [Fig.3].

[0089] In Figures 3, 4, 5, 6 and 8, the scale for representing the spacing D between the The antennas Aj on the one hand and the distance representation scale d(IDi+i, ID;) on the other hand are not the same. In Figures 3, 4, 5, 6 and 8, although it is not shown there, the upper side PSUP of each object 201, 202, 203, 204 touches the lower side PINF of the object 201, 202, 203, 204 located above in the stack 200.

[0090] The computer 4 is configured to provide, during the thirteenth step E13, on the physical output 5 of the conformity verification device 1000, a fourth INFH placement direction information upwards, indicating that the devices 2010, 2020, 2030, 2040 for emitting the identifiers ID, H ID;, IDi+i, IDi+2 of the objects 201, 202, 203, 204 are all located, in the vertical stack 200, closer to their upper side PSUP than closer to their lower side PINF along the vertical direction Z, in the second case where the computer 4 has determined during the eleventh step E11 that the vertical interval ME is greater than or equal to the smallest mini(d(IDi+i, ID;)) of the distances d(IDi+i, ID;).

[0091] This case is represented by way of non-limiting example in [Fig.4].

[0092] This allows the user to verify the conformity of the assembly objects 201, 202, 203, 204 from stack 200, indicating to the user either the direction of placement upwards, or the direction of placement downwards.

[0093] According to one embodiment, in figures IB and 7, in the database B1 are pre-recorded further, in association with each ID identifier; either a PRH prescription of upward orientation of the device 2010, 2020, 2030, 2040 of emitting the ID identifier; of the object 201, 202, 203, 204, or a PRB prescription of downward orientation of the device 2010, 2020, 2030, 2040 of emitting the ID identifier; of object 201, 202, 203, 204, for index i from 1 to M. The process includes the following other steps, which are carried out by the computer 4, in the case where the process includes the following other steps, carried out by the computer 4 after the twelfth step E12 or after the thirteenth step E13.

[0094] The calculator 4 is configured to obtain, during the fourteenth step E14 after the twelfth step E12 or after the thirteenth step E13, the PR prescription for the orientation of the emission device 2010, 2020, 2030, 2040 associated with at least one of the IDs, called the queried ID, from the database B1. This PR prescription thus obtained for the orientation of the emission device 2010, 2020, 2030, 2040 associated with the queried ID can therefore be either the PRH prescription for the upward orientation of the emission device 2010, 2020, 2030, 2040 of the ID; of object 201, 202, 203, 204, i.e. the PRB prescription of downward direction of installation of device 2010, 2020, 2030, 2040 of emission of the ID identifier;.

[0095] The calculator 4 is configured to, in the first case mentioned above, examine during the fifteenth step E15 after the fourteenth step E14 following the twelfth step El2, whether there is an equality between the prescription PR obtained of the direction of installation of the device 2010, 2020, 2030, 2040 of emission of the queried identifier ID; and the third INFB information of the direction of installation downwards. Calculator 4 is configured to, in the second case mentioned above, examine during the other fifteenth step E15bis after the fourteenth step E14 following the thirteenth step E13, whether there is an equality between the prescription PR obtained of the direction of installation of the device 2010, 2020, 2030, 2040 of emission of the queried identifier IDi and the fourth information INFH of direction of installation upwards.

[0096] The computer 4 is configured to, in the case where the computer 4 has determined during the step E15 or E15bis that there was equality, provide during the sixteenth step E16, on the physical output 5, in addition to the second information INFCONF and the third or fourth information INFH, INFB of direction of placement, a fifth information INFCOR of correct positioning of the objects 201, 202, 203, 204 of the stack 200.

[0097] The computer 4 is configured to, in the case where the computer 4 has determined during the step E15 or E15bis that there was no equality, provide during the seventeenth step E17, on the physical output 5, in addition to the second information INFCONF and the third or fourth information INFH, INFB of the direction of placement, a sixth information INFNCOR of incorrect positioning of the objects 201, 202, 203, 204 of the stack 200.

[0098] According to a first family of embodiments, represented in figures IC and 7 and using the PRH prescription of upward installation direction or the PRB prescription of downward installation direction from the B1 database, the method includes the following other steps, which are carried out by the computer 4, in the case where the computer 4 has determined during the fourth step E4 that the first distance d(IDi+i, ID;) is less than or equal to the first theoretical height H1TH, i.e. after the sixth step E6.

[0099] This case is represented by way of non-limiting example in [Fig.6].

[0100] The calculator 4 is configured to query, during the eighteenth step El8, the database B1, to find out the information which is associated with the first identifier ID; and with the second identifier IDi+i.

[0101] As shown in [Fig.7], in database B1, a height INDH indication between the upper side PSUP of object 201, 202, 203, 204 bearing the ID identifier and the lower side PINF of object 201, 202, 203, 204 bearing the ID identifier, and either a PRH prescription for installation direction upwards or a PRB prescription for installation direction downwards, for the index i ranging from 1 to M.

[0102] In one embodiment, the INDH height indications may be equal to each other for all ID identifiers;.

[0103] In another embodiment, several (or all) of the INDH height indications are different from each other for several (or all) of the ID identifiers;.

[0104] The calculator 4 is configured to calculate, during the nineteenth step E19, a third theoretical vertical deviation DTHii+i between the 2010, 2020, 2030, 2040 emission device bearing the first ID identifier; and the 2010, 2020, 2030, 2040 emission device bearing the second ID identifier IDi+i as a function of the PRH or PRB installation prescription associated in the B1 database with the first ID identifier; , of the INDH height indication associated in the B1 database with the first ID identifier; , of the PRH or PRB installation prescription associated in the B1 database with the second ID identifier IDi+i and of the INDH height indication associated in the B1 database with the second ID identifier IDi+i.

[0105] The calculator 4 is configured to compare, during the twentieth step E20, the first distance d(IDi+i, ID;) to the third theoretical vertical gap DTHii+i.

[0106] The computer 4 is configured to provide, during the twenty-first step E21, on the physical output 5 of the conformity verification device 1000, in addition to the first information INFNCONF, a seventh information INFCOR; i+i of correct positioning of the first object 202 bearing the first identifier ID; and of the second object 203 bearing the second identifier IDi+i relative to each other, in the case where the computer 4 has determined during the twentieth step E20 that the absolute value | d(IDi+i, ID;) - DTHii+i | of the difference between the first distance d(IDi+i, IDi) and the third theoretical vertical deviation DTHii+i is less than a prescribed, non-zero threshold TH2.

[0107] The prescribed TH2 threshold may be equal, for example, to the determined antenna spacing D, or may be something else.

[0108] The computer 4 is configured to provide, during the twenty-second step E22, on the physical output 5 of the conformity verification device 1000, in addition to the first INFNCONF information, an eighth INFNCORIJI+I information of incorrect positioning of the first object 202 bearing the first identifier ID; and of the second object 203 bearing the second identifier IDI+I relative to each other, in the case where the computer 4 has determined during the twentieth step E20 that the absolute value |d(IDDI+I, ID;) - DTHII+I| of the difference between the first distance d(IDDI+I, IDI) and the third theoretical vertical deviation DTHII+I is greater than or equal to the prescribed threshold TH2.

[0109] This allows the user to verify the conformity of the direction of placement of two successive objects determined in relation to each other, in the case of step E6.

[0110] According to an embodiment of the first family, shown in Figures IC and 7, the calculator 4 is configured to calculate, during the nineteenth step E19, the third theoretical vertical deviation DTHii+i as being equal to the sum of the INDH height indication associated in database B1 with the first identifier ID; and the INDH height indication associated in database B1 with the second identifier IDi+i, in the case where the first identifier ID; is associated in database B1 with the PRB prescription of downward installation direction and where the second identifier IDi+i is associated in database B1 with the PRH prescription of upward installation direction. This case corresponds to the third theoretical vertical deviation DTHi i+i belonging to the class of so-called remote identifiers for the identifiers IDi+i and IDi+i.

[0111] This case is represented by way of non-limiting example in [Fig.5].

[0112] Calculator 4 is configured to calculate, during the nineteenth step E19, The third theoretical vertical gap DTHiji+i is set to zero when the first identifier ID; is associated in database B1 with the PRH prescription for upward insertion and the second identifier IDi+i is associated in database B1 with the PRB prescription for downward insertion. This case corresponds to the third theoretical vertical gap DTHii+i, belonging to the class of identifiers that are considered "close" (or "near") for the identifiers IDi+i and IDi+i.

[0113] This case is represented by way of non-limiting example in [Fig.6].

[0114] According to an embodiment of the first family, shown in figures IC and 7, the calculator 4 is configured to perform the other subsequent steps, for example after the twenty-first step E21 or after the twenty-second step E22.

[0115] The calculator 4 is configured to query, during the twenty-third step E23, the database B1, to find out the information which is associated with the third identifier IDm, corresponding to the third estimated height h( ID 4), which is located below the first height h(ID;) following this first height h(ID;) in descending order.

[0116] The calculator 4 is configured to calculate, during the twenty-fourth step E24, a fourth theoretical vertical deviation DTH, Ll between the 2010, 2020, 2030, 2040 emission device bearing the first ID identifier; and the 2010, 2020, 2030, 2040 emission device bearing the third ID identifier IDi4 as a function of the PRH, PRB installation prescription associated in database B1 with the first ID identifier; , of the INDH height indication associated in database B1 with the first ID identifier; , of the PRH, PRB installation prescription associated in database B1 with the third ID identifier, h of the INDH height indication associated in database B1 with the third ID identifier,.

[0117] As before, for example, the calculator 4 is configured to calculate, during the twenty-fourth step E24, the fourth theoretical vertical deviation DTH; u as being equal to the sum of the INDH height indication associated in database B1 with the third ID identifier, and the INDH height indication associated in database B1 with the first ID identifier, in the case where the third ID identifier is associated in database B1 with the PRB prescription of downward installation direction and where the first ID identifier is associated in database B1 with the PRH prescription of upward installation direction.

[0118] This case is represented by way of non-limiting example in [Fig.6].

[0119] As before, for example, calculator 4 is configured to calculate, during the twenty-fourth step E24, the fourth theoretical vertical deviation DTHi-u as being equal to zero, in the case where the third identifier ID, is associated in the database B1 with the prescription PRH of installation direction upwards and where the first identifier ID; is associated in the database B1 with the prescription PRB of installation direction downwards.

[0120] This case is represented by way of non-limiting example in [Fig.5].

[0121] The calculator 4 is configured to compare to the fourth theoretical vertical deviation DTH; 14, during the twenty-fifth step E25, the second distance dflD, h ID; ) (or second difference), calculated between the first height h(ID;) and the estimated third height h(ID, J, which corresponds to the third identifier (ID, J. We therefore have d(IDu, ID;) = | h(IDi) - h(IDi J | .

[0122] The computer 4 is configured to provide, during the twenty-sixth step E26, on the physical output 5 of the conformity verification device 1000, a ninth INFCOR information; of correct positioning of the first object 20) bearing the first identifier ID; and of the third object 201 bearing the third identifier ID, 1 relative to each other, in the case where the computer 4 has determined during the twenty-fifth step E25 that the absolute value | d(ID; i, ID;) - DTHmj | of the difference between the second distance d(ID; b ID;) and the fourth theoretical vertical deviation DTH; i; is less than the prescribed threshold TH2.

[0123] The computer 4 is configured to provide, during the twenty-seventh step E27, on the physical output 5 of the conformity verification device 1000, a tenth INFNCOR; incorrect positioning information of the first object 202 bearing the first identifier ID;, in the case where the computer 4 has determined during the twenty-fifth step E25 that the absolute value | d(ID; i, ID;) - DTHmj | of the difference between the second distance d(ID; i, ID;) and the fourth theoretical vertical deviation DTH; i; is greater than or equal to the prescribed threshold TH2.

[0124] This allows the user to verify the conformity of the direction of installation of the first object 202 bearing the first identifier ID; to the PRH prescription of direction of installation upwards for this first object 202 or to the PRB prescription of direction of installation downwards for this first object 202.

[0125] According to an embodiment of the first family, shown in Figures IC and 7, the computer 4 is configured to perform the other subsequent steps, for example after the twenty-sixth step E26 or after the twenty-seventh step E20. Of course, the steps below could be performed after the twenty-first step E21 or after the twenty-second step E22 and before the twenty-third step E23.

[0126] The calculator 4 is configured to query, during the twenty-eighth step E28, the database B1, to find out the information which is associated with the fourth identifier IDi+ 2, corresponding to the fourth estimated height h(IDi+2), which is located above the second height h(IDi+i) in ascending order.

[0127] The calculator 4 is configured to calculate, during the twenty-ninth step E29, a fifth theoretical vertical deviation DTHi+iii+2 between the 2010, 2020, 2030, 2040 emission device bearing the second identifier IDi+i and the 2010, 2020, 2030, 2040 emission device bearing the fourth identifier IDi+2 as a function of the PRH, PRB installation prescription associated in the B1 database with the second identifier IDi+i, the INDH height indication associated in the B1 database with the second identifier IDi+i, the PRH, PRB installation prescription associated in the B1 database with the fourth identifier IDi+2, the INDH height indication associated in the B1 database with the fourth identifier IDi+2.

[0128] As before, for example, calculator 4 is configured to calculate, during the twenty-ninth step E29, the fifth theoretical vertical deviation DTH; +i,i+2 as being equal to the sum of the INDH height indication associated in database B1 with the second identifier IDi+i and the INDH height indication associated in database B1 with the fourth identifier IDi+2, in the case where the second identifier IDi+i is associated in database B1 with the PRB prescription of downward installation direction and where the fourth identifier IDi+2 is associated in database B1 with the PRH prescription of upward installation direction.

[0129] This case is represented by way of non-limiting example in [Fig.6].

[0130] As before, for example, calculator 4 is configured to calculate, during the twenty-ninth step E29, the fifth theoretical vertical deviation DTHi+i i+2 as being equal to zero, in the case where the second identifier IDi+i is associated in database B1 with the prescription PRH of installation direction upwards and the fourth identifier IDi+2 is associated in database B1 with the prescription PRB of installation direction downwards.

[0131] This case is represented by way of non-limiting example in [Fig.5].

[0132] The calculator 4 is configured to compare at the fifth theoretical vertical deviation DTH; 1 during the thirtieth step E30, the third distance d(IDi+i, IDi+2) (or third difference), having been calculated between the second height h(IDi+i) and the third height h(IDi+2), which corresponds to the fourth identifier ID; +2. We therefore have d(IDi+1, IDi+2) = | h(IDi+2) - h(IDi+1) | .

[0133] The computer 4 is configured to provide, during the thirty-first step E31, on the physical output 5 of the conformity verification device 1000, an eleventh piece of information INFCORi+i i+2 of correct positioning of the second object 203 bearing the second identifier IDi+i and of the fourth object 204 bearing the fourth identifier IDi+2 relative to each other, in the case where the computer 4 has determined during the thirtieth step E30 that the absolute value | d(IDi+i, IDi+2) - DTHi+u+2 | of the difference between the third distance d(IDi+i, IDi+2) and the fifth theoretical vertical deviation DTHi+u+2 is less than the prescribed threshold TH2.

[0134] The computer 4 is configured to provide, during the thirty-second step E32, on the physical output 5 of the conformity verification device 1000, a twelfth INFNCORi+i information of incorrect positioning of the second object 203 bearing the second identifier IDi+i, in the case where the computer 4 has determined during the thirtieth step E30 that the absolute value | d(IDi+i, IDi+2) - DTHi+u+2 | of the difference between the third distance d(IDi+i, IDi+2) and the fifth theoretical vertical deviation DTHi+u+2 is greater than or equal to the prescribed threshold TH2.

[0135] This allows the user to verify the conformity of the direction of installation of the second object 203 bearing the second identifier IDi+i to the PRH prescription of direction of installation upwards for this second object 203 or to the PRB prescription of direction of installation downwards for the second object 203.

[0136] According to one embodiment, the prescribed TH2 threshold is a fourth linear or affine function of the determined antenna spacing D according to the following fourth formula: TH2= e*D+f, where e is a prescribed fifth real coefficient, not zero, and f is a prescribed sixth real coefficient and * denotes multiplication.

[0137] For example, 0 < e < 0.5. For example, e = 0.5 and f = 0. Of course, the fifth coefficient e and the sixth coefficient f can have values ​​other than these examples. Of course, TH2 can have values ​​other than these examples.

[0138] According to one embodiment, each object 201, 202, 203, 204 of the stack 200 is chosen from the group consisting of a pneumatic casing P and an assembly mounted R, P comprising a pneumatic casing P and a wheel R on which the pneumatic casing P is mounted.

[0139] According to one embodiment, the device 2010, 2020, 2030, 2040 for emitting an ID identifier; of the objects 201, 202, 203, 204 of the stack 200 is included in the group consisting of a radio frequency identification tag and a pressure and / or temperature sensor of the pneumatic envelope P.

[0140] According to a second family of embodiments, represented in [Fig. IC], the method comprises the following steps, which are carried out by the computer 4, in the case where the computer 4 has determined during the fifth step E54 that the distance d(IDi+1, IDi), called the first distance, calculated between the first estimated height h(IDi) corresponding to the first identifier IDi and a second estimated height h(IDi + 1), which corresponds to a second identifier IDi+1 and which is located above the first height h(IDi) following this first height h(IDi) in ascending order, is less than or equal to the first theoretical height H1TH, for example after the sixth step E6.

[0141] This case is represented by way of non-limiting example in [Fig.8A], where the scale of representation of the spacing D between the antennas Aj on the one hand and the scale of representation of the distances d(IDi+l, IDi) on the other hand are not the same.

[0142] The second family of embodiments, represented in [Fig.1C], has the same embodiments as those described above for the first family of embodiments, with the following modifications.

[0143] As shown in [Fig.9], in the B1 database according to the second family of embodiments, a first vertical gap DID;PINF between the 2020 device of issue of the ID; and the lower side PINF of the object bearing the ID; and a second vertical gap DID;PSUP between the 2010, 2020, 2030, 2040 device of issue of the ID; and the upper side PSUP of the object bearing the ID.

[0144] This is shown by way of non-limiting example in [Fig.8A].

[0145] The sum of the first vertical gap DID;PINF and the second vertical gap DID;PSUP is equal to the INDH height indication between the upper side PSUP of the object bearing the identifier ID; and the lower side PINF of the object bearing the identifier ID;.

[0146] According to one embodiment of the invention, the first theoretical height H1TH is greater than twice the minimum of the first vertical gaps DID;PINF and the second vertical gaps DID;PSUP on the ID identifiers;.

[0147] In the embodiment of steps E18, E19, E20, E21 and E22 of the second family, the calculator 4 is configured to calculate, during the nineteenth step E19, the third theoretical vertical gap DTHii+i, which is equal to the sum of the second vertical gap DID;PSUP associated in database B1 with the first identifier IDi and the first vertical gap DIDi+iPINF associated in database B1 with the second identifier IDi+i.

[0148] This allows the user to have a more precise verification of the conformity of the direction of placement of two successive objects determined in relation to each other, in the case of step E6.

[0149] For the first PRH prescription with the installation direction upwards, the first vertical gap DID;PINF is greater than the second vertical gap DID;PSUP. For the second PRB prescription with the installation direction downwards, the first vertical gap DID;PINF is smaller than the second vertical gap DID;PSUP.

[0150] In the embodiment of steps E23, E24, E25, E26 and E27 of the second family, the calculator 4 is configured to calculate, during the twenty-fourth step E24, the fourth theoretical vertical deviation DTHmj, which is equal to the sum of the second vertical deviation DID |PSUP associated in database B1 with the third identifier ID^ and the first vertical deviation DID;PINF associated in database B1 with the first identifier ID;.

[0151] This is shown by way of non-limiting example in [Fig.8A].

[0152] This allows the user to have a more precise verification of the conformity of the direction of installation of the first object 202 bearing the first identifier ID; to the PRH prescription of direction of installation upwards for this first object 202 or to the PRB prescription of direction of installation downwards for this first object 202.

[0153] In the embodiment of steps E28, E29, E30, E31 and E31 of the second family, the calculator 4 is configured to calculate, during the twenty-ninth step E29, a fifth theoretical vertical deviation DTHi+i i+2, which is equal to the sum of the second vertical deviation DIDi+iPSUP associated in database B1 with the second identifier IDi+i and the first vertical deviation DIDi+2PINF associated in database B1 with the fourth identifier IDi+2.

[0154] This is shown by way of non-limiting example in [Fig.8A].

[0155] This allows the user to have a more precise verification of the conformity of the direction of installation of the second object 203 bearing the second identifier IDi+i to the PRH prescription of direction of installation upwards for this second object 203 or to the PRB prescription of direction of installation downwards for the second object 203.

[0156] In the preceding figures, 7 and 9, the database B1 may have been pre-recorded in a memory 40 of the computer 4. In a variant not shown in the figures, the database B1 may have been pre-recorded in a memory that is remote from the computer 4 and that can be connected to the computer 4. via a telecommunications network, the computer 4 having for this purpose telecommunications means to communicate with the database B1.

[0157] In the preceding, in Figures 7 and 9, it may have been pre-recorded in database B1 for all objects 201, 202, 203, 204 the associations of a unique name of each object 201, 202, 203, 204 to the identifier ID; of each device 2010, 2020, 2030, 2040 of issuance of this identifier ID; provided on each object 201, 202, 203, 204. The names are different from each other.

[0158] According to a non-limiting example, in memory 40, the name of object 201 may be "front left tire", the name of object 202 may be "front right tire", the name of object 203 may be "rear left tire", the name of object 204 may be "rear right tire", in the case where objects 201, 202, 203, 204 are to be used to equip a four-wheeled motor vehicle.

[0159] It may have been pre-recorded in database B1 for each object 201, 202, 203, 204 the associations of a type of each object 201, 202, 203, 204 to the identifier ID; of each device 2010, 2020, 2030, 2040 of emission of this identifier ID; provided on each object 201, 202, 203, 204. In the example mentioned above in [Fig.2], this type may be a type of pneumatic envelope P. The various types of pneumatic envelope P may be symmetric pneumatic, directional pneumatic and axisymmetric pneumatic.

[0160] For a symmetrical tire P, the positioning of the device 2010, 2020, 2030, 2040 for issuing the ID identifier is always located on one side of the tire, linked to the structural conicity of the tire, either on the outer sidewall bearing the regulatory marking or on the inner sidewall. Therefore, on the vehicle, it is one or the other depending on this positioning at the time of tire manufacturing.

[0161] A directional pneumatic tire P has a symbol on its sidewalls in the form of an arrow indicating the direction of rotation of the tire around its axis. This tire P may have, in side view, a clockwise arrow on the right sidewall and a counterclockwise arrow on the left sidewall. The B1 database indicates on which sidewall the ID 2010, 2020, 2030, or 2040 emitting device is located. The directional pneumatic tire P dictates a mounting direction on the vehicle. On the vehicle, the wheels mounted on the right side have the ID 2010, 2020, 2030, or 2040 emitting device. on the outside of the vehicle, that is, on the side of the wheel rim. However, the Wheels mounted on the left side of the vehicle have the 2010, 2020, 2030, 2040 ID identification emitting device; inside the vehicle, away from the wheel rim.

[0162] For an axisymmetric pneumatic tire P, there is an inner sidewall (in English, "inside") intended to be on the inside of the vehicle and an outer sidewall (in English, "outside") intended to be on the outside of the tire. The B1 database indicates on which sidewall the ID 2010, 2020, 2030, 2040 emitting device is located. The axisymmetric pneumatic tire P dictates a mounting direction on the vehicle. If the ID 2010, 2020, 2030, 2040 emitting device is located on the outer sidewall, the ID 2010, 2020, 2030, 2040 emitting device is located on the outside of the vehicle, on the wheel rim side. If the 2010, 2020, 2030, 2040 ID identification emission device; is located on the inner side, the 2010, 2020, 2030, 2040 ID identification emission device; is located on the inside of the vehicle, away from the wheel rim.

[0163] Querying database B1 during step E1 or E16 or E21 using detected IDs allows determining the side where the ID 2010, 2020, 2030, 2040 emitting device is present on the object (for example: inner or outer sidewall of the tire for a symmetrical tire P, left or right sidewall for a directional tire P (direction of the arrow in the sidewall marking), inner or outer sidewall for an axisymmetric tire P).

[0164] Querying database B1 during step El 1 or E16 or E21 using detected IDs allows us to know the desired arrangement of objects 201, 202, 203, 204 in stack 200 according to the position of the objects on the vehicle and the desired presentation direction of the objects (for example, outer sidewall of the tire on top or outer sidewall of the tire underneath or alternately, which can be equivalent to the wheel rim on top or underneath or alternately).

[0165] Embodiments of the calculation of the estimated height h(ID;) of each identifier IDi having been detected by the detection device 3 are described below, during the second step E2 by the calculator 4.

[0166] According to one embodiment, shown in Figures 11, 12, 16 and 17, the verification device 1000 includes a rotation device 11 for rotating the vertical stack 200 of objects 201, 202, 203, 204 at least once around a vertical axis 212 of rotation with respect to the N radio frequency antennas Aj. The vertical axis 212 of rotation is parallel to the vertical direction Z. For example, in the case of [Fig. 2], the vertical axis 212 of rotation is parallel to the central geometric axis 210 of the stack 200 or coincides with the geometric axis central 210 of the stack 200. For example, in Figures 11, 12, 16, and 17, the rotation device 11 is positioned in front of the N radio frequency antennas Aj and is configured to rotate the vertical stack 200 of objects 201, 202, 203, 204 around the vertical axis 212 of rotation in front of the N radio frequency antennas Aj to complete at least one relative rotation. The rotation device 11 includes a rotating lower platform 110 that can be rotated about itself around the vertical axis 212 of rotation relative to a fixed base 111. The N radio frequency antennas Aj are positioned outside the rotation device 11.Of course, in other embodiments not shown, the rotation device 11 could be configured to rotate the N radio frequency antennas Aj around the vertical axis 212 of rotation and around the vertical stack 200 of objects 201, 202, 203, 204 to perform at least one relative rotation. Of course, in other embodiments not shown, the rotation device 11 could be configured to rotate both the N radio frequency antennas Aj and the vertical stack 200 of objects 201, 202, 203, 204 around the vertical axis 212 of rotation to perform at least one relative rotation.

[0167] According to one embodiment, shown in Figures 10, 13, 14 and 15, the detection device 3 is configured to measure the detection event(s) Aj>k of each ID of each object 201, 202, 203, 204 by each radio frequency antenna Aj during relative rotation for at least one (or more) duration D, each duration D corresponding to the revolution(s) of relative rotation. Each detection event Ajjk corresponds to the fact that the radio frequency antenna Aj detects the ID of one of the objects 201, 202, 203, 204 over time and is a temporal measurement associated with the ID that was detected by or via the radio frequency antenna Aj. Each Ajjk detection event can be a time peak of power, which is received by the radio frequency antenna Aj and which is associated with the identifier ID;, which was detected by the radio frequency antenna Aj or via the radio frequency antenna Aj.The index k is a fifth natural number used to denote each detection event Aj>k, which was obtained by the radio frequency antenna Aj of each set 31 or 32 or via the radio frequency antenna Aj of each set 31 or 32.

[0168] According to one embodiment, the second step E2 of the verification process comprises a first substep E31, during which the vertical stack 200 of objects 201, 202, 203, 204 is rotated by the rotation device 11 to perform the number Q of rotations of the vertical stack 200 of objects 201, 202, 203, 204 around the vertical axis 212 of rotation with respect to the N radio frequency antennas Aj and during which the device 3. Detection event(s) Ajjk, for each ID of each object 201, 202, 203, 204 and for each radio frequency antenna Aj, of the detection event(s) Ajjk of the ID of each object 201, 202, 203, 204 by the radio frequency antenna Aj during the relative rotation for the duration(s) D, each duration D corresponding to the number Q of relative rotation(s). The number Q of relative rotation(s) is greater than or equal to 1. The number Q of relative rotation(s) may be greater than or equal to 2. In one embodiment of the invention, the number Q of relative rotation(s) may be a sixth natural number greater than or equal to 1. The number Q of relative rotation(s) may be a sixth natural number greater than or equal to 2.The detection device 3 is configured to retrieve the ID identifiers of objects 201, 202, 203, 204, obtained by the detection event(s) Aj>k of these objects by each radio frequency antenna Aj during the relative rotation for the duration(s) D, each duration D corresponding to the turn(s) of relative rotation.

[0169] During the first substep E31, the measurement of the event(s) Ajjk by the detection device 3 can be performed when the rotation device 11 rotates the vertical stack of objects 201, 202, 203, 204 at a constant or stabilized relative speed, with respect to the N radio frequency antennas Aj. This avoids discriminating between one area and another. This is desirable when the number Q of wheel rotations is limited and is an integer.

[0170] On the other hand, if the number Q of turns is high, this number Q is not necessarily an integer, since a real number Q is sufficient.

[0171] According to one embodiment, the calculator 4 is configured to calculate during the second substep E32 of the second step E2 a parameter Yen as a function of the detection event(s) Ajjk.

[0172] The rotation device 11 can be controlled by the computer 4.

[0173] The parameter Yjd.ÇAj^ decreases with the distance of the respective ID emission device 2010, 2020, 2030, 2040 from the radio frequency antenna Aj in each detection event Ajjk. For example, the detection event Aj>k can occur when the ID passes closest to the radio frequency antenna Aj or in a prescribed position relative to the radio frequency antenna Aj during the relative rotation for the duration(s) D, each duration D corresponding to the number Q of relative rotation(s), i.e., when the ID is in the near field within the reception range of the radio frequency antenna Aj.This makes it possible not to interrogate all the transmitting devices 2010, 2020, 2030, 2040 in a single angular position of the stack 200 around the axis 212 of rotation and to obtain a diversified reception power of the transmitting devices 2010, 2020, 2030, 2040 by the radio frequency antennas Aj. Each antenna. A radio frequency antenna Aj has a principal pointing direction of its main radiation lobe (in its radiation pattern), which represents the direction in which the radio frequency antenna Aj is able to receive the most emitted power relative to all directions emanating from the radio frequency antenna Aj in the three dimensions of space. According to one embodiment of the invention, the radio frequency antennas Aj are oriented in the same way, that is, the principal pointing directions of the radio frequency antennas Aj are parallel and in the same direction, so as not to favor one of the radio frequency antennas Aj in the parameter Yjj). ( Aj^} ■

[0174] Embodiments of this parameter F / p. ( A^ ) are described below.

[0175] According to one embodiment, the calculator 4 is configured to calculate during the second substep E32 of the second step E2 for each identifier ID; of each object 201, 202, 203, 204 a weighted average m(ID;) according to the following equation: °where is a weighting proportional to the position in Yj^YiD^Ajjc) height of the antenna Aj along the vertical direction Z.

[0176] The weighting Hj. can be, for example, the difference in height of the position of the antenna Aj relative to a height reference, which could be, for example, that of the rotation device 11, or other.

[0177] According to one embodiment, the estimated height h(ID;) of each identifier ID; that has been detected by the detection device 3 is equal to the weighted average m(ID u.

[0178] This has the advantage of increasing, in the weighted average m(ID;), the weighting of antennas Aj having a large Yjd.^Aj^ reception parameter of the ID; compared to the weighting of antennas Aj having a smaller F / / y ( Aj^ ) reception parameter of this ID;. This improves the estimated vertical position of each ID; of each object 201, 202, 203, 204 by the weighted average m(ID;).

[0179] Thus, for example, in the case of ID identifiers formed in [Fig. 2] by the ID identifiers ID2, ID3, ID4 of objects 201, 202, 203, 204 respectively, the calculator 4 calculates m(IDi) for the IDi identifier of object 201 that has been detected, m(ID2) for the ID2 identifier of object 202 that has been detected, m(ID3) for the ID3 identifier of object 203 that has been detected, and m(ID4) for the ID4 identifier of object 204 that has been detected. In this case, the calculator 4 calculates: m(IDi) < m(ID2) < m(ID3) < m(ID4).

[0180] According to one embodiment, the calculator 4 is configured to determine during the third substep E33 of the second step E2 the vertical ORD order, from bottom to top, of the objects 201, 202, 203, 204 corresponding to the ID identifiers; according to the ascending direction of the weighted means m(ID;) having been calculated (or the vertical ORD order, from top to bottom, of the objects 204, 203, 202, 201 corresponding to the ID identifiers IDi according to the descending direction of the weighted means m(ID;) having been calculated).

[0181] Thus, for example in the case of the ID identifiers; formed in [Fig.2] by the ID identifiers IDb ID2, ID3, ID4 respectively of the objects 201, 202, 203, 204, the calculator 4 deduces from the fact that m(IDi) < m(ID2) < m(ID3) < m(ID4) the order ORD of the ID identifiers IDb ID2, ID3, ID4 from bottom to top and therefore the order ORD of the objects 201, 202, 203, 204 from bottom to top (or the order ORD of the ID identifiers ID4, ID3, ID2, IDi from top to bottom and therefore the order ORD of the objects 204, 203, 202, 201 from top to bottom).

[0182] The physical output 5 is capable of providing during the third sub-step E33 of the second step E2 an INF information indicating the ORD order of the objects 201, 202, 203, 204 having been determined by the computer 4, from bottom to top (or from top to bottom).

[0183] This allows a reliable vertical ranking of ID identifiers read and objects 201, 202, 203, 204 to be provided on the physical output 5 according to their actual position in the stack 200.

[0184] According to a first embodiment of the second step E2, the calculator 4 is configured to calculate during the second substep E32 of the second step E2 as parameter Y / d^A calculated as a function of the detection event(s) Aj>k the number nbjD.^A^) of detection events Ajk of the identifier ID; of each object 201, 202, 203, 204 by the radio frequency antenna Aj during the relative rotation during the duration(s) D, each duration D corresponding to the number Q of turn(s) of relative rotation of the vertical stack 200 of the objects 201, 202, 203, 204 around the vertical axis 212 of rotation with respect to the N radio frequency antennas Aj.

[0185] We therefore have: FID. (Aj^) = nbS!) (Ajj().

[0186] Thus, the computer 4 is configured to count during the second substep E32 of the second step E2 the number of times nbu).( Aj^ ) that an event Aj>k of detection of the identifier ID; is obtained by the radio frequency antenna Aj during the relative rotation during the duration (or durations) D, each duration D corresponding to the number Q of turn(s) of relative rotation of the vertical stack 200 of the objects 201, 202, 203, 204 around the vertical axis 212 of rotation with respect to the N radio frequency antennas Aj.

[0187] Thus, the calculator 4 is configured to count, during the second substep E32 of the second step E2, the number of times nbio. ( Aj^ ) that the identifier ID; is detected by the radio frequency antenna Aj during the relative rotation during the duration(s) D, each duration D corresponding to the number Q of revolution(s) of relative rotation of the vertical stack 200 of objects 201, 202, 203, 204 around the vertical axis 212 of rotation with respect to the N radio frequency antennas Aj.

[0188] Thus, the computer 4 is configured to count during the second sub-step E32 of the second step E2 the number llbuj ( Aj^ ) of time peak(s) of power, which is(s) received by the radio frequency antenna Aj and with which the identifier ID; (the time peak(s) of power being therefore associated with the identifier ID;) was detected by the radio frequency antenna Aj or via the radio frequency antenna Aj during the relative rotation during the duration D, each duration D corresponding to the number Q of turn(s) of relative rotation of the vertical stack 200 of the objects 201, 202, 203, 204 around the vertical axis 212 of rotation with respect to the N radio frequency antennas Aj.

[0189] A flowchart of the verification process according to this first embodiment of the invention is shown in [Fig. 13].

[0190] Thus, according to this first embodiment of the invention, the calculator 4 is configured to calculate during the second sub-step E32 of the second step E2 for each identifier ID; of each object 201, 202, 203, 204 the weighted average m(ID;) according to the following equation: wd j D = ------- \

[0191] The weighted average m(ID;) of this first embodiment of the invention is thus an estimate of the vertical position of each identifier ID; of each object 201, 202, 203, 204 along the Z direction.

[0192] This first embodiment therefore has the advantage of increasing in the weighted average m(ID;) the weighting of antennas Aj having a large number of times nbij). ( Aj^) that the identifier ID; is detected by these compared to the weighting of antennas Aj having a smaller number tlbij). ( Ay& j for this identifier ID;. This improves the estimated vertical position of each identifier ID; of each object 201, 202, 203, 204 by the weighted average m(ID;).

[0193] According to a second embodiment of the second step E2, the calculator 4 is configured to calculate, during the second substep E32 of the second step E2, as a parameter m^Aj^) calculated as a function of the detection event(s) Ajjk, the sum S / d) Aj) = HkPiD ( Aj^ ), over the detection events Ajjk, the powers / 'jp.j Aj^) with which the identifier ID; of each object 201, 202, 203, 204 is detected by the radio frequency antenna Aj in each detection event Aj k, during the relative rotation during the duration(s) D, each duration D corresponding to the number Q of relative rotation(s) of the vertical stack 200 objects 201, 202, 203, 204 around the vertical axis 212 of rotation with respect to the N radio frequency antennas Aj.

[0195] The detection device 3 is configured to measure, during the first substep E31 of the second step E2, the power Pjd^ Aj# ) of each detection event Ajjk of each ID identifier; of each object 201, 202, 203, 204 by each radio frequency antenna Aj during the relative rotation during the duration (or durations) D, each duration D corresponding to the number Q of turns of relative rotation of the vertical stack 200 of the objects 201, 202, 203, 204 around the vertical axis 212 of rotation with respect to the N radio frequency antennas Aj.

[0196] Thus, the detection device 3 is configured to measure, during the first substep E31 of the second step E2, the power Pjd^ Ajl) with which each detection event Aj k of each identifier ID; of each object 201, 202, 203, 204 is received by each radio frequency antenna Aj during the relative rotation during the duration (or durations) D, each duration D corresponding to the number Q of turn(s) of relative rotation of the vertical stack 200 of the objects 201, 202, 203, 204 around the vertical axis 212 of rotation with respect to the N radio frequency antennas Aj.

[0197] Thus, the calculator 4 is configured to calculate during the second sub-step E32 of the second step E2 the sum (Aj) of the powers Pu).(Aj^) of the time peaks of power, which is(s) received by the radio frequency antenna A j and with which (which) the identifier ID; (the time peak(s) of power being therefore associated with the identifier ID;) was detected by the radio frequency antenna Aj or via the radio frequency antenna Aj during the relative rotation during the duration D, each duration D corresponding to the number Q of turn(s) of relative rotation of the vertical stack 200 of the objects 201, 202, 203, 204 around the vertical axis 212 of rotation with respect to the N radio frequency antennas Aj.

[0198] A flowchart of the verification process according to this second embodiment of the invention is shown in [Fig.14].

[0199] Thus, according to this second embodiment of the second step E2, the calculator 4 is configured to calculate during the second substep E32 of the second step E2 for each identifier ID; of each object 201, 202, 203, 204 the weighted average m(ID;) according to the following equation:

[0200] The weighted average m(ID;) of this second embodiment of the invention is thus an estimate of the vertical position of each identifier ID; of each object 201, 202, 203, 204 along the Z direction.

[0201] This second embodiment therefore has the advantage of increasing in the weighted average m(ID;) the weighting SjD.(Aj) of some of the antennas Aj having a high power Pmi(AjJi) for receiving the identifier ID; compared to the weighting Sm ( Aj) of the other antennas Aj having a lower power PlD^Aj# ) for receiving this identifier ID;. This improves the estimated vertical position of each identifier ID; of each object 201, 202, 203, 204 by the weighted average m(ID;).

[0202] The power Pin^Aj* ) of each detection event Aj>k of each ID; of each object 201, 202, 203, 204 can be the received signal strength indicator RSSI (received signal strength indicator) by each radio frequency antenna Aj. This received signal strength indicator RSSI can be measured by the detection device 3 during the first substep El of step E.

[0203] According to a third embodiment of the second step E2, the calculator 4 is configured to calculate, during the second substep E32 of the second step E2, as a parameter Ym^Aj^ ) calculated as a function of the detection event(s) Aj>k, the parameter Xm. ( Aj ) of weighting of the detection events Aj>k of the identifier ID; of each object (201, 202, 203, 204) by the radio frequency antenna Aj during the relative rotation during the duration(s) D, each duration D corresponding to the number Q of turns of relative rotation of the vertical stack 200 of the objects 201, 202, 203, 204 around the vertical axis 212 of rotation with respect to the N radio frequency antennas Aj.

[0204] The parameter Xm. ( Aj ) is equal to 1 when piD* (Aj)^B' ( PtDi ( Aj* ) ), where PlD^) is the power with which the identifier ID; of each object (201, 202, 203, 204) is detected by the radio frequency antenna Aj in each Aj>k detection event.

[0205] The parameter XIDi(Aj) is equal to at least one value greater than or equal to 0 and less than 1 when Pm. ( Aj* ) <B ’ max^ ( PiD; ( Ajk ) ) • Par exemple, X1Di(Aj) = 0 lorsque PID. ( Ay^ ) < B max^ ( Pid{ ( Ajk ) ) •

[0206] Le maXAik(P H),(Aj^)) est le maximum des puissances Pm.^ ( Aj ) sur les antennes radiofréquences Aj et sur les évènements Aj>k of detection.

[0207] B is a prescribed threshold, which is greater than 0 and less than 1. For example, B is greater than or equal to 0.5. For example, B may be equal to 0.9 or 0.95, or other.

[0208] The calculated value B • maXA^ ( PlD, ( Ajk ) ) is a threshold of received power for detect the ID identifier; by the radio frequency antennas Aj. ​

[0209] The detection device 3 is configured to measure, during the first sub-step E31 of the second step E2, the power Pid.ÇAj^ of each detection event Aj>k of each ID identifier; of each object 201, 202, 203, 204 by each radio frequency antenna Aj during the relative rotation during the duration (or durations) D, each duration D corresponding to the number Q of turns of relative rotation of the vertical stack 200 of the objects 201, 202, 203, 204 around the vertical axis 212 of rotation with respect to the N radio frequency antennas Aj.

[0210] Thus, the detection device 3 is configured to measure, during the first substep E31 of the second step E2, the power Pjd^ ^jk) with which each detection event Aj k of each identifier ID; of each object 201, 202, 203, 204 is received by each radio frequency antenna Aj during the relative rotation during the duration (or durations) D, each duration D corresponding to the number Q of turn(s) of relative rotation of the vertical stack 200 of the objects 201, 202, 203, 204 around the vertical axis 212 of rotation with respect to the N radio frequency antennas Aj.

[0211] A flowchart of the verification process according to this third embodiment of the invention is shown in [Fig. 15].

[0212] Thus, according to this third embodiment of the second step E2, the calculator 4 is configured to calculate during the second substep E32 of the second step E2 for each identifier ID; of each object 201, 202, 203, 204 the weighted average m(ID;) according to the following equation: w ID: = ------ \ /

[0213] The weighted average m(ID;) of this second embodiment of the second step E2 is thus an estimation of the vertical position of each ID identifier; of each object 201, 202, 203, 204 along the Z direction.

[0214] This third embodiment therefore has the advantage of further increasing, compared to the second embodiment, in the weighted average m(IDi), the weighting X / p.

[0215] The Pid power ( ) of each Aj>k detection event of each identifier The IDi of each object 201, 202, 203, 204 can be the received signal strength indicator (RSSI) for each radio frequency antenna Aj. This received signal strength indicator (RSSI) can be measured by the detection device 3 during the first substep El of step E. This third embodiment therefore has the advantage in this case of focusing the weighted average m(ID;) of the identifier ID; read on the antenna Aj with the highest received signal strength indicator (RSSI).

[0216] Embodiments of the invention are described below, which can be combined with the features described above and each of the embodiments described above.

[0217] According to one embodiment of the invention, in the first substep E31, the radio frequency antennas Aj are all activated simultaneously in radio frequency reception mode to receive the ID identifiers; of objects 201, 202, 203, 204 during the relative rotation of the vertical stack 200 of objects 201, 202, 203, 204 around the vertical axis 212 with respect to the N radio frequency antennas Aj during the duration D, each duration D corresponding to the number Q of turn(s) during the first substep El.

[0218] According to another embodiment of the invention, in the first substep E31, the N radio frequency antennas Aj are activated one after the other by the computer 4 each for the duration (or durations) D in radio frequency reception mode corresponding to the relative rotation of the vertical stack 200 of objects 201, 202, 203, 204 around the vertical axis 212 with respect to the N radio frequency antennas Aj.Thus, the radio frequency antennas Aj are activated one after the other (without interruption or with interruption between the radio frequency antennas Aj) by the computer 4, each for a duration D of activation in radio frequency reception mode to receive the ID(s) of objects 201, 202, 203, 204 during the relative rotation of the vertical stack 200 of objects 201, 202, 203, 204 around the vertical axis 212 with respect to the N radio frequency antennas Aj during each activation duration D corresponding to the number Q of turns during the first sub-step El. There are therefore successively N activation durations D in reception mode for the N radio frequency antennas Aj respectively.During each activation time D in radio frequency reception mode, the rotation device 11 causes the vertical stack 200 of objects 201, 202, 203, 204 to perform the number Q of rotation turns relative to the N radio frequency antennas Aj and the detection device 3 measures, for each ID identifier; of each object 201, 202, 203, 204 and for the radio frequency antenna Aj which is in reception mode. radio frequency, the event(s) Aj>k of detection of the identifier ID; of each object 201, 202, 203, 204 by the radio frequency antenna Aj during the relative rotation for the activation time D corresponding to the number Q of relative rotation turns. For example, each activation time D can correspond to one relative rotation turn of the vertical stack 200 of objects 201, 202, 203, 204 around the vertical axis 212 with respect to the N radio frequency antennas Aj, that is, Q=1 for each activation time D.

There are therefore several successive activation times D in reception mode for the radio frequency antennas Aj of each subgroup.During each activation time D in radio frequency reception mode, the rotation device 11 causes the vertical stack 200 of objects 201, 202, 203, 204 to perform the number Q of relative rotation turns of the vertical stack 200 of objects 201, 202, 203, 204 around the vertical axis 212 of rotation with respect to the N radio frequency antennas Aj and the detection device 3 measures, for each identifier IDi of each object 201, 202, 203, 204 and for the respective subgroup of radio frequency antennas Aj which is in radio frequency reception mode, the detection event(s) Aj>k of the identifier ID of each object 201, 202, 203, 204 by the respective subgroup of radio frequency antennas Aj during the relative rotation during the activation time D corresponding to the number Q of relative rotation turns.For example, each activation time D can correspond to one relative rotation of the vertical stack 200 of objects 201, 202, 203, 204 around the vertical axis 212 with respect to the N radio frequency antennas Aj, i.e. Q=1 for each activation time D.
