[0001] DESCRIPTION

[0002] Method and device for verifying the conformity of the orientation of objects placed in a stack

[0003] The invention relates to a method and a device for verifying the conformity of the orientation of objects placed in a stack.

[0004] The field of the invention relates to the logistical management of connected or connectable goods.

[0005] We know of systems in which vertically spaced radio frequency antennas allow the detection of radio frequency emitting devices, such as RFID tags, of objects in the stack.

[0006] One of the problems with these systems is to reliably and automatically determine the direction in which objects are placed in the stack.

[0007] Indeed, placing an object in the stack in the wrong direction wastes time processing the stack of objects, when this placement direction must obey rules.

[0008] 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.

[0009] 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 form 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,performed 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 an indication of height between the upper side of the object bearing the identifier and the lower side of the object bearing the identifier, comparison of each distance to a first prescribed 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 identifier and is located above the first height following that first height in ascending order, is less than or equal to the first theoretical height, providing, on a physical output, initial information indicating that the objects are not all placed in the same direction in the vertical stack, in the case where the computer has determined that the first distance is greater than the first theoretical height, comparison of the first distance to a second theoretical height, which is a function of the height indications associated with the first identifier and the second identifier, in the case where the computer has determined that the first distance is greater than the second theoretical height, providing, on the physical output, initial information indicating that the objects are not all placed in the same direction in the vertical stack,In the event that the computer has determined that the first distance is less than or equal to the second theoretical height, it provides, on a physical output, a second piece of information indicating that the objects are all placed in the same orientation in the vertical stack.

[0050] 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 also described below. The verification device 1000 is configured to implement the verification method.

[0051] As illustrated by way of example in Figure 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.

[0052] Each object 201, 202, 203, 204 is equipped with one (or more) respective devices 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 ID identifier and the respective object 201, 202, 203, 204 identified by this respective ID identifier. The index i is a second natural number from 1 to M. It can be predicted that the same number (one or more) of devices) 2010, 2020, 2030, 2040 respectively will issue the ID identifier on each object 201, 202, 203, 204. Each ID identifier can be a string of characters, or other.

[0053] On each object 201, 202, 203, 204 in the vertical stack 200, the device 2010, 2020, 2030, 2040 for emitting the ID identifier of object 201, 202, 203, 204 is located closer to an upper edge PSUP of object 201, 202, 203, 204 along the vertical Z direction if the device 2010, 2020, 2030, 2040 for emitting the ID identifier is placed with its orientation facing upwards in the vertical stack 200, or is located closer to a lower edge PINF of object 201, 202, 203, 204 along the vertical Z direction if the device 2010, 2020, The 2030 and 2040 issue dates of the IDi identifier are placed with the orientation facing downwards. The vertical Z direction is oriented from bottom to top.

[0054] For example, as shown in Figure 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.

[0055] In Figures 11, 12, 16, and 17, the verification device 1000 includes a device 3 for detecting IDs. The detection device 3 comprises 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 ranging from 1 to N.

[0056] The successive radio frequency antennas Aj and A j+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.

[0057] According to one embodiment of the invention, the determined antenna spacing D may be uniform between the antennas Aj. 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.

[0058] 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 IDi of that object 201, 202, 203, 204 and the lower side PINF of the object 201, 202, 203, 204 bearing the identifier ID of that 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 the objects 201, 202, 203, 204 may be different from one another. According to one embodiment of the invention, each INDH height of the object 201, 202, 203, 204 can be greater than or equal to a prescribed minimum height value.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] In Figure IA, the method for verifying the conformity of the placement direction 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 ID detection device 3. The device 3 detects the ID identifiers IDi of the objects 201, 202, 203, 204 in the vertical stack 200. In one embodiment, the ID 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.

[0063] The method for verifying the conformity of the placement direction of objects 201, 202, 203, and 204 includes the following additional steps, performed by a computer 4. The computer 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; that is, the vertical position of each identifier ID of each object 201, 202, 203, and 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 computer 4 in a manner other than these embodiments.

[0064] Calculator 4 is configured to classify, during the third step E3, the estimated heights h(ID) and h(ID 1+ i) in ascending or descending order along the vertical direction Z.

[0065] For example, Figures 2, 3, 4, 5, 6, 8, and 12 consider the 2010, 2020, 2030, and 2040 devices for issuing IDM and ID identifiers, respectively. b ID 1+ i, ID 1+ 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.

[0066] Calculator 4 is configured to calculate distances d(ID) during the third step E3 1+ i, ID ) between the estimated heights h(IDi) and h(ID 1+ i) having been sorted in ascending or descending order along the vertical direction Z, for i ranging from 1 to M-1. The calculator therefore calculates during the third step E3 each distance d(ID 1+i, ID ) as being equal to the absolute value of the difference between the successive estimated heights h(IDi) and h(ID 1+ i) in ascending or descending order.

[0067] So we have

[0068] As shown in Figure 7, the 1000 device includes a database B1, in which an ID is pre-registered in association with each identifier. b an INDH height measurement between the upper side PSUP of the object bearing the ID identifier and the lower side PINF of the object bearing the ID identifier b for the index i ranging from 1 to M.

[0069] Calculator 4 is configured to query, during the fourth step E4, database B 1 by ID identifiers to obtain the associated INDH height indications.

[0070] Calculator 4 is configured to compare, during the fifth step E5, each distance d(ID 1+i, ID) to a first prescribed theoretical height H1TH.

[0071] The computer 4 is configured to provide, during the sixth step E6 on the physical output 5 of the conformity verification device 1000, initial 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(ID 1+ 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(ID 1+ i) estimated heights, which corresponds to a second ID 1+iof 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(ID 1+ i, ID ) = | h(ID 1+ i) - W | .

[0072] Calculator 4 is configured to compare, during the seventh step E7, the first distance d(ID 1+ i, ID) to a second theoretical height H2TH 1>1+ i, which is a function of the INDH height indications associated with the first ID identifier and the second ID identifier 1+ i, in the case where the calculator 4 has determined during the fifth step E5 that the first distance d(ID 1+ i, ID) is greater than the first theoretical height H1TH.

[0073] The computer 4 is configured to provide, during the eighth step E8, on the physical output 5, the 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 determined during the seventh step E7 that the first distance d(ID 1+ i, ID) is greater than the second theoretical height H2TH 1>1+i .

[0074] The computer 4 is configured to provide, during the ninth step E9, on the physical output 5, a second INFCONF information indicating that objects 201, 202, 203, 204 are all placed in the same orientation in the vertical stack 200, in the case where the computer 4 determined during the seventh step E7 that the first distance d(ID 1+ i, ID) is less than or equal to the second theoretical height H2TH 1>1+i .

[0075] This allows the user to verify that all objects 201, 202, 203, and 204 in stack 200 conform to a single orientation. This orientation can be either upwards or downwards.

[0076] 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.

[0077] Specifically, Figure 8B corresponds to a case where the first ID identifier is associated in database B1 with the PRB prescription for downward installation direction, where the third ID identifier i is associated in database B1 with the PRB prescription for downward installation direction, where the second ID identifier 1+i is associated in database B1 with the PRH prescription for upward insertion, and where the fourth identifier is ID 1+2 is associated in database B 1 with the PRH prescription for installation direction upwards.

[0078] 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:

[0079] H1TH= a*D+b , where a is a first prescribed real coefficient, b is a second prescribed real coefficient and * denotes multiplication.

[0080] 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.

[0081] In another embodiment, the first theoretical height HITH is a function of the material thickness of the tire casing P of objects 201, 202, 203, and 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, and 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.

[0082] According to one embodiment, the INDH height indication associated with the first IDi identifier is equal to the INDH height indication associated with the second ID identifier 1+i The second theoretical height H2TH 1>1+i is a second linear or affine function of the INDH height indication associated with the first ID identifier and the second ID identifier 1+i according to the following second formula: H2TH 11+i = c*INDH, where c is a third prescribed real coefficient, not zero and * denotes multiplication.

[0083] 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.

[0084] In another embodiment, the INDH! height indication associated with the first ID identifier is different from the INDH indication 1+i height associated with the second ID identifier 1+ i. The second theoretical height H2TH 1>1+i is a third linear or affine function of the INDH! indication of height associated with the first ID identifier and of the INDH indication 1+i height associated with the second ID identifier 1+i according to the following third formula:

[0085] H2TH 11+i = k*(INDHi + INDH 1+ i) , where k is a prescribed, non-zero fourth real coefficient and * denotes multiplication. For example, k > 0.7. For example, k = 0.9. Of course, the fourth coefficient k can have values ​​other than these examples.

[0086] According to one embodiment, in Figure IB, 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.

[0087] 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 Figure 2 is the height h(ID1.i) corresponding to the identifier ID , ) and a reference point REF of an upper surface 211 supporting the vertical stack 200 of objects 201, 202, 203, 204.

[0088] Calculator 4 is configured to determine during the eleventh step El 1 the smallest mini(d(IDi+i, ID,)) of the distances d(ID 1+ i, ID ) on the index i ranging from 1 to Ml.

[0089] Calculator 4 is configured to compare, during the eleventh step El i, the vertical interval ME to the smallest mini(d(IDi+i, ID,)) of the distances d(ID 1+ i, ID0.

[0090] The calculator 4 is configured to provide, during the twelfth step El 2, 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 issue IDM, ID identifiers b ID 1+ i, ID 1+2 of the objects 201, 202, 203, 204 are all located, in the vertical stack 200, closer to their bottom side PINF than to their top side PSUP along the vertical direction Z, in the first case where the computer 4 determined during the eleventh step El i that the vertical interval ME is less than the smallest mini(d(IDi+i, ID,)) of the distances d(ID 1+ i, ID0.

[0091] This case is represented as a non-limiting example in Figure 3.

[0092] Figures 3, 4, 5, 6 and 8 show the scale representing the spacing D between the antennas Aj on the one hand, and the scale representing the distances d(ID) on the other. 1+ 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.

[0093] The calculator 4 is configured to provide, during the thirteenth step El 3, 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 issue IDM, ID identifiers b ID 1+ i, ID 1+ 2 of the objects 201, 202, 203, 204 are all located, in the vertical stack 200, closer to their upper side PSUP than to their lower side PINF along the vertical direction Z, in the second case where the computer 4 determined during the eleventh step El i that the vertical interval ME is greater than or equal to the smallest mini(d(IDi+i, ID,)) of the distances d(ID 1+ i, IDO.

[0094] This case is represented as a non-limiting example in Figure 4.

[0095] This allows the user to verify the conformity of all objects

[0096] 201, 202, 203, 204 of stack 200, indicating to the user either the upward or downward orientation.

[0097] According to one embodiment, in figures IB and 7, in database B1 are pre-recorded, in association with each ID identifier, either a PRH prescription for upward orientation of the device 2010, 2020, 2030, 2040 of emission of the ID identifier of the object 201,

[0098] 202, 203, 204, i.e. a PRB prescription of downward direction of the device 2010, 2020, 2030, 2040 of emission of the ID identifier of the object 201, 202, 203, 204, for the index i ranging from 1 to M.

[0099] The process includes the following further steps, which are carried out by the computer 4, in the case where the process includes the following further steps, carried out by the computer 4 after the twelfth step E12 or after the thirteenth step E13.

[0100] 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 direction of installation of the emission device 2010, 2020, 2030, 2040 associated with at least one of the ID identifiers b called query identifier ID b from database B1. This PR prescription thus obtained for the orientation of the 2010, 2020, 2030, 2040 emission device associated with the queried ID identifier can therefore be either the PRH prescription for upward orientation of the 2010, 2020, 2030, 2040 emission device with the ID identifier of object 201, 202, 203, 204, or the PRB prescription for downward orientation of the 2010, 2020, 2030, 2040 emission device with the ID identifier b

[0101] 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 El 2, 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 direction of installation downwards.

[0102] 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 ID and the fourth information INFH of direction of installation upwards. 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.

[0103] Computer 4 is configured to, in the event that computer 4 has determined during step E15 or E15bis that there was no equality, provide during the seventeenth step E17, on physical output 5, in addition to the second information INFCONF and the third or fourth information INFH, INFB of placement direction, a sixth information INFNCOR of incorrect positioning of objects 201, 202, 203, 204 of stack 200.

[0104] According to a first family of embodiments, shown in Figures IC and 7 and using the PRH prescription for upward installation direction or the PRB prescription for downward installation direction from database B1, the method comprises 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(ID 1+i, ID) is less than or equal to the first theoretical height H1TH, that is after the sixth step E6.

[0105] This case is represented as a non-limiting example in Figure 6.

[0106] Calculator 4 is configured to query, during the eighteenth step El 8, database B1, to find the information associated with the first ID and the second ID 1+i .

[0107] As shown in Figure 7, database B1 contained pre-recorded data associated with each ID identifier. b an INDH height indication between the upper side PSUP of object 201, 202, 203, 204 bearing the identifier ID and the lower side PINF of object 201, 202, 203, 204 bearing the identifier ID b and, either a PRH prescription with the direction of installation upwards, or a PRB prescription with the direction of installation downwards, for the index i ranging from 1 to M.

[0108] In one embodiment, the INDH height indications may be equal for all ID identifiers b

[0109] In another embodiment, several (or all) of the INDH height indications are different from each other for several (or all) of the ID identifiers b

[0110] Calculator 4 is configured to calculate, during the nineteenth step El 9, a third theoretical vertical deviation DTH 1>1+i between the 2010, 2020, 2030, 2040 issuing device bearing the first ID identifier and the 2010, 2020, 2030, 2040 issuing device bearing the second ID identifier 1+ i depending on the PRH or PRB prescription for placement associated in the B1 database with the first ID identifier b of the INDH height indication associated in the B1 database with the first ID identifier bof the PRH or PRB prescription for placement associated in database B 1 with the second ID identifier 1+i and the INDH height indication associated in the B1 database with the second ID identifier 1+i .

[0111] Calculator 4 is configured to compare, during the twentieth step E20, the first distance d(ID 1+ i, ID) at the third theoretical vertical gap DTH 1>1+ i.

[0112] 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 INFNCONF information, a seventh INFCOR information, i+i, indicating the correct positioning of the first object 202 bearing the first ID and the second object 203 bearing the second ID. 1+i one with respect to the other, in the case where the calculator 4 has determined during the twentieth step E20 that the absolute value the difference between the first distance d(IDi+i, IDi) and the third theoretical vertical gap DTH 1>1+i is below a prescribed, non-zero TH2 threshold.

[0113] The prescribed TH2 threshold may be equal, for example, to the determined antenna spacing D, or it may be something else.

[0114] 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 piece of information INFNCOR, i+i indicating incorrect positioning of the first object 202 bearing the first ID and of the second object 203 bearing the second ID. 1+i one with respect to the other, in the case where the calculator 4 has determined during the twentieth step E20 that the absolute value the difference between the first distance d(IDi+i, IDi) and the third theoretical vertical gap DTH 1>1+iis greater than or equal to the prescribed TH2 threshold.

[0115] This allows the user to verify the conformity of the placement direction of two successive objects determined in relation to each other, in the case of step E6.

[0116] 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 El 9, the third theoretical vertical deviation DTH 1>1+i as being equal to the sum of the INDH height indication associated in database B1 with the first ID identifier and the INDH height indication associated in database B1 with the second ID identifier 1+ i, in the case where the first ID identifier is associated in database B 1 with the PRB prescription for downward insertion direction and where the second ID identifier 1+iis associated in database B 1 with the PRH prescription for upward installation direction. This case corresponds to the third theoretical vertical deviation DTH 1>1+i belonging to the class of so-called remote identifiers for ID identifiers 1+i and ID 1+i .

[0117] This case is represented as a non-limiting example in Figure 5.

[0118] Calculator 4 is configured to calculate, during the nineteenth step El 9, the third theoretical vertical deviation DTH 1>1+i as being equal to zero, in the case where the first ID identifier is associated in database B 1 with the PRH prescription for upward insertion and where the second ID identifier 1+i is associated in database B 1 with the PRB prescription for downward installation direction. This case corresponds to the third theoretical vertical deviation DTH 1>1+i belonging to the class of so-called "stuck" (or close) identifiers for ID identifiers 1+iand ID 1+ i.

[0119] This case is represented as a non-limiting example in Figure 6.

[0120] 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.

[0121] Calculator 4 is configured to query, during the twenty-third step E23, database B1, to find out the information which is associated with the third identifier IDM, corresponding to the third estimated height h(ID1.i), which is located below the first height h(ID!) following this first height h(ID!) in descending order.

[0122] Calculator 4 is configured to calculate, during the twenty-fourth step E24, a fourth theoretical vertical deviation DTH, | between the 2010, 2020, 2030, 2040 emission device bearing the first ID and the 2010, 2020, 2030, 2040 emission device bearing the third ID i according to the PRH, PRB installation prescription associated in database B1 with the first ID b of the INDH height indication associated in the B1 database with the first ID identifier b of the PRH prescription, PRB placement associated in the B 1 database with the third IDM identifier, of the INDH height indication associated in the B1 database with the third IDM identifier.

[0123] As before, for example, calculator 4 is configured to calculate, during the twenty-fourth step E24, the fourth theoretical vertical deviation DTH, i, as being equal to the sum of the INDH height indication associated in database B1 with the third identifier IDM and the INDH height indication associated in database B1 with the first identifier ID b In the case where the third ID identifier is associated in database B1 with the PRB prescription for downward insertion and where the first ID identifier is associated in database B1 with the PRH prescription for upward insertion. This case is shown as a non-limiting example in Figure 6.

[0124] As before, for example, calculator 4 is configured to calculate, during the twenty-fourth step E24, the fourth theoretical vertical deviation DTH,| as being equal to zero, in the case where the third ID i identifier is associated in database B1 with prescription PRH of upward installation direction and where the first ID identifier is associated in database B1 with prescription PRB of downward installation direction.

[0125] This case is represented as a non-limiting example in Figure 5.

[0126] Calculator 4 is configured to compare, at the fourth theoretical vertical deviation DTHMJ, during the twenty-fifth step E25, the second distance d(IDi-i, ID) (or second difference), calculated between the first height h(ID!) and the estimated third height h(ID1.i), which corresponds to the third identifier (ID, ). We therefore have d(IDi-i, ID) = |h(IDi) - h(IDi-i)|.

[0127] 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 INFCORMJ 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 i relative to each other, in the case where the computer 4 has determined during the twenty-fifth step E25 that the absolute value | d(IDi-i, ID ) - DTH,.| | of the difference between the second distance d(IDi-i, ID ) and the fourth theoretical vertical deviation DTH,.| is less than the prescribed threshold TH2.

[0128] 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 INFNCORi information of incorrect positioning 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(IDi-i, ID ) - DTH|.| | of the difference between the second distance d(IDi-i, ID ) and the fourth theoretical vertical deviation DTH,.| is greater than or equal to the prescribed threshold TH2.

[0129] This allows the user to verify the conformity of the installation direction of the first object 202 bearing the first ID identifier to the PRH prescription of installation direction upwards for this first object 202 or to the PRB prescription of installation direction downwards for this first object 202.

[0130] According to an embodiment of the first family, shown in Figures IC and 7, the computer 4 is configured to perform the following 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.

[0131] Calculator 4 is configured to query database B1 during the twenty-eighth step E28 to retrieve the information associated with the fourth ID. 1+ 2, corresponding to the fourth height h(ID 1+ 2) estimated, which is located above the second height h(ID 1+ i) in ascending order.

[0132] Calculator 4 is configured to calculate, during the twenty-ninth step E29, a fifth theoretical vertical deviation DTH 1+ I >1+2 between the 2010, 2020, 2030, 2040 issue device bearing the second ID identifier 1+i and the 2010, 2020, 2030, 2040 issuance device bearing the fourth ID identifier 1+ 2. Based on the PRH, PRB prescription associated with the placement in database B1, the second ID identifier 1+ i, of the INDH height indication associated in the B1 database with the second ID identifier 1+ i, of the PRH prescription, PRB placement associated in the B1 database with the fourth ID identifier 1+ 2, of the INDH height indication associated in the B1 database with the fourth ID identifier 1+ 2.

[0133] As before, for example, calculator 4 is configured to calculate, during the twenty-ninth step E29, the fifth theoretical vertical deviation DTH 1+ I >1+2 as being equal to the sum of the INDH height indication associated in database B1 with the second ID identifier 1+i and the INDH height indication associated in the B1 database with the fourth ID identifier 1+ 2, in the case where the second ID identifier 1+i is associated in database B1 with the PRB prescription for downward insertion direction and where the fourth identifier ID 1+ 2 is associated in database B 1 with the PRH prescription for installation direction upwards.

[0134] This case is represented as a non-limiting example in Figure 6.

[0135] As before, for example, calculator 4 is configured to calculate, during the twenty-ninth step E29, the fifth theoretical vertical deviation DTH 1+ I >1+ 2 as being equal to zero, in the case where the second ID identifier 1+iis associated in database B 1 with the PRH prescription for upward insertion and the fourth ID identifier 1+ 2 is associated in database B1 with the PRB prescription of downward direction of installation.

[0136] This case is represented as a non-limiting example in Figure 5.

[0137] Calculator 4 is configured to compare the fifth theoretical vertical deviation DTH-y, during the thirtieth step E30, with the third distance d(ID 1+ i, ID | 2 ) (or third difference), having been calculated between the second height h(ID 1+ i) and the third height h(ID 1+ 2), which corresponds to the fourth ID identifier 1+ 2. Therefore, we have The calculator 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 INFCOR+i, I+2 indicating the correct positioning of the second object 203 bearing the second ID identifier 1+i and the fourth object 204 bearing the fourth ID identifier 1+ 2 relative to each other, in the case where the calculator 4 has determined during the thirtieth step E30 that the absolute value | d(ID 1+ i, ID, ?) - DTH l+i ,i+2 1 of the difference between the third distance d(IDi+i, ID1+2) and the fifth theoretical vertical gap DTH 1+ I, 1+ 2 is below the prescribed TH2 threshold.

[0138] 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 piece of information INFNCOR1+1 indicating incorrect positioning of the second object 203 bearing the second identifier ID1+1, in the case where the computer 4 has determined during the thirtieth step E30 that the absolute value | d(IDi+i, ID1+2) - DTH1+1 ,1+2 1 of the difference between the third distance d(IDi+i, ID1+2) and the fifth theoretical vertical deviation DTH 1+ I, 1+ 2 is greater than or equal to the prescribed TH2 threshold.

[0139] This allows the user to verify the correct orientation of the second object 203 bearing the second ID. 1+i to the PRH prescription of upward direction of installation for this second object 203 or to the PRB prescription of downward direction of installation for the second object 203.

[0140] 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:

[0141] 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.

[0142] 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.

[0143] According to one embodiment, each object 201, 202, 203, 204 of the stack 200 is chosen from the group consisting of a pneumatic envelope P and a mounted assembly R, P comprising a pneumatic envelope P and a wheel R on which the pneumatic envelope P is mounted.

[0144] According to one embodiment, the device 2010, 2020, 2030, 2040 for emitting an IDi identifier from 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 for the pneumatic casing P. According to a second family of embodiments, shown in Figure 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(ID 1+ i, ID0, called the first distance, calculated between the first estimated height h(ID!) corresponding to the first identifier ID and a second estimated height h(ID 1+ i), which corresponds to a second ID identifier 1+iand 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, for example after the sixth step E6.

[0145] This case is represented as a non-limiting example in Figure 8A, where the scale for representing the spacing D between the antennas Aj on the one hand and the scale for representing the distances d(ID) on the other 1+ i, ID ) on the other hand are not the same.

[0146] The second family of embodiments, represented in figure IC, has the same embodiments as those described above for the first family of embodiments, with the following modifications.

[0147] As shown in Figure 9, in database B 1 according to the second family of embodiments, a first vertical gap DID PINF between the device 2020 of emitting the ID and the lower side PINF of the object bearing the ID and a second vertical gap DIDæSUP between the device 2010, 2020, 2030, 2040 of emitting the ID and the upper side PSUP of the object bearing the ID were pre-recorded in association with each ID.

[0148] This is represented as a non-limiting example in Figure 8A.

[0149] 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.

[0150] 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.

[0151] 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 deviation DTH 1>1+ i, which is equal to the sum of the second vertical gap DIDæSUP associated in database B 1 with the first identifier ID and the first vertical gap DID 1+ iPINF associated in database B 1 with the second ID identifier 1+i .

[0152] This allows the user to verify the correct orientation of two successive objects relative to each other, as in step E6. For the first PRH specification with upward orientation, the first vertical deviation DID PINF is greater than the second vertical deviation DID PSUP. For the second PRB specification with downward orientation, the first vertical deviation DID PINF is smaller than the second vertical deviation DID PSUP.

[0153] 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 i PSUP associated in the database B1 with the third identifier ID i and the first vertical deviation DIDælNF associated in the database B1 with the first identifier ID.

[0154] This is represented as a non-limiting example in Figure 8A.

[0155] This allows the user to have a more precise verification of the conformity of the installation direction of the first object 202 bearing the first ID identifier to the PRH prescription of installation direction upwards for this first object 202 or to the PRB prescription of installation direction downwards for this first object 202.

[0156] 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 DTH 1+ i, 1+2, which is equal to the sum of the second vertical deviation DID 1+ iPSUP associated in database B 1 with the second ID identifier 1+i and the first vertical gap DI D2PIN F associated in database B1 with the fourth ID identifier 1+ 2.

[0157] This is represented as a non-limiting example in Figure 8A.

[0158] This allows the user to verify the correct orientation of the second object 203 bearing the second ID. 1+ ià the PRH prescription of upward direction of installation for this second object 203 or to the PRB prescription of downward direction of installation for the second object 203.

[0159] In the preceding, in 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 which is remote from the computer 4 and which 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. In the above, in figures 7 and 9, it may have been pre-recorded in database B 1 for all objects 201, 202, 203, 204 the associations of a unique name of each object 201, 202, 203, 204 to the ID identifier of each device 2010, 2020, 2030, 2040 of issuance of this ID identifier provided on each object 201, 202, 203, 204. The names are different from each other.

[0160] 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.

[0161] 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 ID identifier of each device 2010, 2020, 2030, 2040 of emission of this ID identifier provided on each object 201, 202, 203, 204. In the example mentioned above in Figure 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.

[0162] For a symmetrical tire (P type), the positioning of the device for issuing the IDi identifier (2010, 2020, 2030, 2040) always occurs on one side of the tire, following 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.

[0163] A directional tire (P) has a symbol on its sidewall indicating the direction of rotation around its axis. This tire (P) may have, viewed from the side, a clockwise arrow on the right sidewall and a counterclockwise arrow on the left sidewall. The B1 database specifies which sidewall the ID identification device (IDi) (2010, 2020, 2030, 2040) is located on. The directional tire (P) dictates its mounting direction on the vehicle. On the vehicle, wheels mounted on the right side have the ID identification device (IDi) (2010, 2020, 2030, 2040) on the outside of the vehicle, i.e., on the rim side.In contrast, the wheels mounted on the left side of the vehicle have the 2010, 2020, 2030, 2040 IDi identifier emission device inside the vehicle, away from the wheel rim.

[0164] For an axisymmetric tire (P type), 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 identification device (2010, 2020, 2030, 2040) is located. The axisymmetric tire (P type) dictates a mounting direction on the vehicle. If the ID identification device (2010, 2020, 2030, 2040) is located on the outer sidewall, the ID identification device (Tl) is located on the outside of the vehicle, on the wheel rim side. If the 2010, 2020, 2030, 2040 IDi identifier emission device is located on the inner sidewall, the 2010, 2020, 2030, 2040 IDi identifier emission device is located on the inside of the vehicle, away from the wheel rim.

[0165] Querying database B1 during step E1 or E16 or E21 using detected IDi identifiers allows determining the side where the ID identifier 2010, 2020, 2030, 2040 emission device is present on the object (for example: inner or outer sidewall of the tire for a P tire of symmetrical type, left or right sidewall for a P tire of directional type (direction of the arrow in the sidewall marking), inner or outer sidewall for a P tire of axisymmetric type).

[0166] Querying database B1 during step E1 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).

[0167] Methods of implementing the calculation of the estimated height h(IDi) of each ID identifier that has been detected by the detection device 3 are described below, during the second step E2 by the calculator 4.

[0168] According to one embodiment, shown in Figures 11, 12, 16 and 17, the verification device 1000 includes a rotation device 11 enabling the vertical stack 200 of objects 201, 202, 203, 204 to perform at least one rotation relative to 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 Figure 2, the vertical axis 212 of rotation is parallel to the central geometric axis 210 of the stack 200 or coincides with the central geometric axis 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, and 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 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.

[0169] 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 object ID of each object 201, 202, 203, 204 by each radio frequency antenna Aj during the relative rotation for at least one (or more) duration D, each duration D corresponding to the revolution(s) of relative rotation. Each detection event Aj,k corresponds to the radio frequency antenna Aj detecting the ID of one of the objects 201, 202, 203, 204 over time and is a temporal measurement associated with the ID. b which was detected by the radio frequency antenna Aj or via the radio frequency antenna Aj. Each detection event Aj,k can be a time-domain power peak, which is received by the radio frequency antenna Aj and is associated with the identifier ID bwhich 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 designate 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.

[0170] According to one embodiment, the second step E2 of the verification process includes a first sub-step E31, during which the vertical stack 200 of objects 201 is rotated,

[0171] 202, 203, 204 by the rotation device 11 to make the vertical stack 200 of objects 201, 202, 203, 204 perform the number Q of rotation(s) 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 and during which the detection device 3 measures, for each ID of each object 201, 202, 203, 204 and for each radio frequency antenna Aj, the detection event(s) Aj,k of the ID of each object 201, 202,

[0172] 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 record the IDs of the objects 201, 202, 203, 204, obtained by the detection events 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 relative rotation(s).

[0173] During the first substep E31, the measurement of the event(s) Aj,k 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 prevents discrimination between one area and another. This is desirable when the number Q of wheel rotations is limited and is an integer.

[0174] On the other hand, if the number Q of turns is high, this number Q is not necessarily an integer, because a real number Q is sufficient.

[0175] According to one embodiment, the calculator 4 is configured to calculate, during the second substep E32 of the second step E2, a parameter E / D .( j fe ) depending on the detection event(s) Aj,k.

[0176] The rotation device 11 can be controlled by the computer 4.

[0177] The parameter Y ID .(Aj k^ is decreasing with the respective distance of the transmitting device 2010, 2020, 2030, 2040 of the identifier ID from the radio frequency antenna Aj in each detection event Aj,k. For example, the detection event Aj,k can occur when the identifier 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 turns of relative rotation, i.e. when the identifier 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 radio frequency antenna Aj has a principal pointing direction for 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 Y parameter. ID .

[0178] Implementation methods for this parameter Y ID (AJ) K are described below.

[0179] According to one embodiment, the calculator 4 is configured to calculate during the second substep E32 of the second step E2 for each ID identifier of each object 201, 202,

[0180] 203, 204 a weighted average m(IDi) according to the following equation: where H A . is a weighting proportional to the height position of the antenna Aj along the vertical direction Z. The weighting H A . 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.

[0181] According to one embodiment, the estimated height h(ID!) of each ID identifier that has been detected by the detection device 3 is equal to the weighted average m(IDi).

[0182] This has the advantage of increasing the weighting of antennas Aj with a large parameter Y in the weighted average m(IDi) ID .^Aj )k ) of reception of the ID identifier with respect to the weighting of the antennas Aj having a smaller this parameter Y ID Aj k ) of receiving this IDi identifier. This improves the estimated vertical position of each ID identifier of each object 201, 202, 203, 204 by the weighted average m(IDi).

[0183] Thus, for example, in the case of the ID identifiers formed in Figure 2 by the identifiers IDi, ID2, IDs, ID4 of objects 201, 202, 203, 204 respectively, the calculator 4 calculates m(IDi) for the identifier IDi of the detected object 201, m(ID2) for the identifier ID2 of the detected object 202, m(ID3) for the identifier ID3 of the detected object 203, and m(ID4) for the identifier ID4 of the detected object 204. In this case, the calculator 4 calculates: m(IDi) < m(ID2) < m(ID3) < m(ID4).

[0184] 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 in ascending order of the weighted means m(IDi) that have been calculated (or the vertical ORD order, from top to bottom, of the objects 204, 203, 202, 201 corresponding to the ID identifiers in descending order of the weighted means m(IDi) that have been calculated).

[0185] Thus, for example in the case of the ID identifiers formed in figure 2 by the identifiers IDi, ID2, ID3, ID4 respectively of 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 identifiers IDi, 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 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).

[0186] 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 objects 201, 202, 203, 204 having been determined by computer 4, from bottom to top (or from top to bottom).

[0187] This allows for the reliable provision, on physical output 5, of a vertical ranking of the read IDi identifiers and objects 201, 202, 203, 204 according to their actual position in the stack 200. 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 E / D .( j fe ) calculated based on the detection event(s) Aj,k the number nb ID ^Aj k ) of events 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 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 objects 201, 202, 203, 204 around the vertical axis 212 of rotation with respect to the N radio frequency antennas Aj.

[0188] So we have

[0189] Thus, calculator 4 is configured to count, during the second substep E32 of the second step E2, the number of times nb ID . 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(s) D, each duration D corresponding to the number Q of turns 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-

[0190] Thus, calculator 4 is configured to count, during the second substep E32 of the second step E2, the number of times nb ID . that the identifier ID is detected 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 objects 201, 202, 203, 204 around the vertical axis 212 of rotation with respect to the N radio frequency antennas Aj.

[0191] Thus, calculator 4 is configured to count the number nb during the second substep E32 of the second step E2 ID . of time peak(s) of power, which is / are 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 objects 201, 202, 203, 204 around the vertical axis 212 of rotation with respect to the N radio frequency antennas Aj.

[0192] A flowchart of the verification process according to this first embodiment of the invention is shown in Figure 13.

[0193] 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 ID identifier of each object 201, 202, 203, 204 the weighted average m(IDi) according to the following equation: The weighted average m(IDi) of this first embodiment of the invention is thus an estimate of the vertical position of each ID identifier of each object 201, 202, 203, 204 along the Z direction.

[0194] This first embodiment therefore has the advantage of increasing in the weighted average m(IDi) the weighting of the antennas Aj having a large number of times nb ID Aj k ) that the ID identifier is detected by these with respect to the weighting of the antennas Aj having a smaller number nb ID .(Aj )k) for this ID identifier. This improves the estimated vertical position of each ID identifier of each object 201, 202, 203, 204 by the weighted average m(IDi).

[0195] 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 parameter Y !D (Aj )k ) calculated as a function of the detection event(s) Aj,k the sum S ID . = on the detection events Aj,k, of the powers? / ^ 4 j fe) with which the ID identifier 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 (or durations) D, each duration D corresponding to the number Q of turn(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.

[0196] So we have

[0197] The detection device 3 is configured to measure, during the first sub-step E31 of the second step E2, the power of each event Aj,k of detection 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 turn(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.

[0198] Thus, the detection device 3 is configured to measure, during the first sub-step E31 of the second step E2, the power P IDi (Aj )k) with which each detection event Aj,k of each ID identifier 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 objects 201, 202, 203, 204 around the vertical axis 212 of rotation with respect to the N radio frequency antennas Aj.

[0199] Thus, calculator 4 is configured to calculate, during the second substep E32 of the second step E2, the sum S ID . powers P ID.(Aj,k) of the time peaks of power, which is(s) received by the radio frequency antenna Aj 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.

[0200] A flowchart of the verification process according to this second embodiment of the invention is shown in Figure 14.

[0201] Thus, according to this second embodiment of the second step E2, the calculator 4 is configured to calculate during the second sub-step E32 of the second step E2 for each identifier IDi of each object 201, 202, 203, 204 the weighted average m(IDi) according to the following equation:

[0202] The weighted average m(IDi) of this second embodiment of the invention is thus an estimate of the vertical position of each ID identifier of each object 201, 202, 203, 204 along the Z direction.

[0203] This second embodiment therefore has the advantage of increasing the weighting S in the weighted average m(IDi). ID . of some of the Aj antennas having a high power d £ reception of the ID identifier in relation to the S weighting ID . Aj) of the other antennas Aj having a lower power P ID.(Aj,k) of reception of this ID identifier. This improves the estimated vertical position of each ID identifier of each object 201, 202, 203, 204 by the weighted average m(IDj).

[0204] The power of Pi Di The value of each detection event Aj,k for each object ID 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.

[0205] 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 parameter Y !D (Aj )k ) calculated as a function of the detection event(s) Aj,k, the parameter X ID . of weighting of events 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 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 objects 201, 202, 203, 204 around the vertical axis 212 of rotation with respect to the N radio frequency antennas Aj.

[0206] The parameter X ID .(HAS j ) is equal to 1 when P IDlk (Aj) - B ' max HAS jrk (PiD^j,^), where P IDi ( / ,fc) es tl a power with which the IDi identifier of each object (201, 202, 203, 204) is detected by the radio frequency antenna Aj in each detection event Aj,k.

[0207] The parameter XIDI(AJ) is equal to at least one value greater than or equal to 0 and less than 1 when P ID .(HAS j)k ) < B ■ max A . kFor example, XIDI(AJ) = 0 when P IDl HAS j k ) < B - max A] k {PJD.ÇAJ ).

[0208] The max A . k is the maximum of powers L es radio frequency antennas Aj and on the detection events Aj,k.

[0209] 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 could be equal to 0.9 or 0.95, or something else.

[0210] The calculated value B ■ max A . k is a threshold of received power to detect the ID identifier by the radio frequency antennas Aj.

[0211] The detection device 3 is configured to measure, during the first sub-step E31 of the second step E2, the power P ID.(Aj,k) of each event Aj,k of detection 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 turn(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.

[0212] Thus, the detection device 3 is configured to measure, during the first sub-step E31 of the second step E2, the power P ID.(Aj,k) with which each event Aj,k of detection 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 (or the) duration D, each duration D corresponding to the number Q of turn(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.

[0213] A flowchart of the verification process according to this third embodiment of the invention is shown in Figure 15.

[0214] Thus, according to this third embodiment of the second step E2, the calculator 4 is configured to calculate during the second sub-step E32 of the second step E2 for each identifier IDi of each object 201, 202, 203, 204 the weighted average m(IDi) according to the following equation:

[0215] The weighted average m(IDi) of this second embodiment of the second step E2 is thus an estimate of the vertical position of each ID identifier of each object 201, 202, 203, 204 along the Z direction.

[0216] This third embodiment therefore has the advantage of increasing the weighting X even further compared to the second embodiment, in the weighted average m(IDi). ID . of some of the Aj antennas having a high power P ID .(Aj,k) of ID reception (greater than or equal to the power threshold B ■ max Ajk ^PiD^j,^ P ar relative to the weighting XiDj(Aj) of other antennas Aj having a lower reception power PiDj(Aj7k) of this identifier IDi (below the power threshold B ■ max Aj k (Aj k) . This improves the estimated vertical position of each ID identifier of each object 201, 202, 203, 204 by the weighted average m(IDi).

[0217] The power PiDj(Aj7k) of each detection event Aj,k for each object ID 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(IDi) of the ID read on the antenna Aj with the highest received signal strength indicator (RSSI).

[0218] Embodiments of the invention are described below, which can be combined with the features described above and each of the embodiments described above.

[0219] 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 the objects 201, 202, 203, 204 during the relative rotation of the vertical stack 200 of the 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.

[0220] 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 a duration 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 the activation duration D in radio frequency reception mode to receive the ID(s) of the objects 201,

[0221] 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 time D corresponding to the number Q of turns during the first substep El. There are therefore successively N activation times D in reception mode respectively of the N radio frequency antennas Aj.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 ID identifier of each object 201, 202, 203, 204 and for the radio frequency antenna Aj which is in radio frequency reception mode, the detection event(s) Aj,k of the ID identifier of each object 201, 202, 203, 204 by the radio frequency antenna 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 turn of 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.

[0222] According to another embodiment of the invention, in the first substep E31, the radio frequency antennas Aj are activated sequentially in subgroups. In the first substep E31, several subgroups of the radio frequency antennas Aj are activated by the computer 4 one after the other, each for a duration 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 during the duration D, the subgroups of the radio frequency antennas Aj being disjoint from each other.Thus, the subgroups of the radio frequency antennas Aj are activated one after the other (without interruption or with interruption between the subgroups) by the computer 4 each during the duration D of activation in radio frequency reception mode to receive the IDi identifier(s) of the objects 201, 202, 203, 204 during the relative rotation of the vertical stack 200 of the objects 201, 202,.

[0223] 203, 204 around the vertical axis 212 with respect to the N radio frequency antennas Aj during each activation time D corresponding to the number Q of turns during the first sub-step El. There are therefore successively several activation times D in reception mode respectively of the radio frequency antennas Aj of each sub-group.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 turn of 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.

[0224] Further embodiments of the invention are described below, which can be combined with the features described above and each of the embodiments described above.

[0225] According to an embodiment of the invention, shown in Figure 16, each device 2010, 2020, 2030, 2040 for transmitting the ID identifier of each object 201, 202, 203, 204 comprises a radio frequency transponder capable of transmitting the ID identifier of object 201, 202, 203, 204 in response to an interrogation signal. The same number (one or more) of radio frequency transponder(s) may be provided on each object 201, 202, 203, 204.

[0226] The ID detection device 3 includes at least one reader 6, which is capable of emitting the radio frequency transponder interrogation signal during the relative rotation during the duration (or durations) D, each duration D corresponding to at least one turn during the first substep E31.

[0227] Reader 6 is connected to the N radio frequency antennas Aj and is capable of reading, at each detection event, the IDi identifier of the object 201, 202, 203, 204, which was emitted by at least one of the radio frequency transponders in response to the interrogation signal and which was received by at least one of the radio frequency antennas Aj during the relative rotation during the duration D, each duration D corresponding to at least one turn during the first sub-step E31.

[0228] Reader 6 can emit the interrogation signal continuously during the relative rotation for the duration(s) D, each duration D corresponding to the number Q of turn(s) during the first substep E31.

[0229] Reader 6 allows measurement, for each object ID 201, 202, 203, 204 and for each radio frequency antenna Aj, of the detection event(s) Aj,k of the object ID 201, 202, 203, 204 by the radio frequency antenna Aj during its relative rotation for at least one duration D, as described above. Reader 6 can be associated with computer 4 and / or connected to computer 4 and / or controlled by computer 4.

[0230] According to an example of this embodiment of the invention, shown in Figure 16, each radio frequency transponder is an RFID tag in which the identifier IDi is recorded. Reader 6 is at least one RFID reader 6. RFID is the abbreviation for radio frequency identification. The RFID tag may consist of an electronic chip coupled to a radio antenna (distinct from the antennas Aj).

[0231] According to another embodiment of the invention, represented in figure 11, each device 2010, 2020, 2030, 2040 for emitting the ID identifier of each object 201, 202, 203, 204 comprises an emitter of the ID identifier of the object 201, 202, 203, 204. The same number (one or more) of ID identifier emitter(s) may be provided on each object 201, 202, 203, 204.

[0232] According to an example of this embodiment of the invention, shown in Figures 2 and 11, a pressure and / or temperature sensor for the tire P is attached to the wheel R described above and / or to the tire P described above. The transmitter of the object ID 201, 202, 203, 204 is part of the pressure and / or temperature sensor for the tire P. The pressure and / or temperature sensor for the tire P may be a TPMS (Tire Pressure Monitoring System) and / or TMS (Tire Monitoring System) type sensor. The pressure and / or temperature sensor for the tire P may be provided on a valve of the tire P, which is its inflation nozzle.For example, in stack 200, the pressure and / or temperature sensors, and therefore the respective IDi emitting devices 2010, 2020, 2030, 2040, are all located above the rim level of the R wheel, or are all located below the rim level of the R wheel.

[0233] The two previous embodiments can be combined, by the fact that each object 201, 202, 203, 204 is provided with one (or more) radio frequency transponder capable of emitting the ID identifier of the object 201, 202, 203, 204 in response to an interrogation signal and the emitter of the ID identifier of the object 201, 202, 203, 204 (this ID identifier of the emitter may be a string of characters different from the string of characters of the ID identifier of the radio frequency transponder, or may be a string of characters identical to the string of characters of the ID identifier of the radio frequency transponder).

[0234] According to one embodiment of the invention, the distance between the highest radio frequency antenna Aj and the lowest radio frequency antenna Aj is at least 90% or 95% of the height of the vertical stack 200 of objects 201, 202, 203, 204. This makes it possible to cover all the objects in the stack 200. The distance between the highest radio frequency antenna Aj and the lowest radio frequency antenna Aj can be equal to 100% of the height of the vertical stack 200 of objects 201, 202, 203, 204 or more than 100% of the height of the vertical stack 200 of objects 201, 202, 203, 204.

[0235] According to one embodiment of the invention, the rotation device 11 can have a constant rotation speed to cause the vertical stack 200 of objects 201, 202, 203, 204 to complete at least one relative rotation around the vertical axis 212 of rotation with respect to the N radio frequency antennas Aj. The combination of the integer number Q of rotation(s) and the constant rotation speed ensures fairness of the spatiotemporal area detected by the detection device 3 and improves the determination of the order ORD in a fast acquisition time.

[0236] According to an embodiment of the invention, shown in Figures 11, 12, 16, and 17, the set 31 and / or 32 of N radio frequency antennas Aj can be attached to an arm 310 extending at least vertically over a certain height, for example, parallel to the direction Z. For example, the set 31 of N radio frequency antennas Aj and the set 32 ​​of N other radio frequency antennas Aj are attached to the same arm 310 extending vertically over a certain height, for example, respectively to the right and left of the arm 310, and with a vertical offset between the two sets 31 and 32 so that the vertical positions of the antennas Aj alternate from bottom to top between set 31 and set 32. Each antenna can be attached to the arm 310 by means of an angled bracket 311. Of course, several arms 310 could be provided, which are distributed around the axis 212 of rotation, described below and which each support one or two sets 31 of N radio frequency antennas Aj.

[0237] According to one embodiment of the invention, the battery 200 can be placed on a base 211 facilitating the movement of the battery 200. This base 211 forms the upper support surface 211 for the vertical stack 200 of the objects 201, 202, 203, and 204. The base 201 can be equipped on the face opposite the face in contact with the battery 200 with means of movement, such as casters, for example (not shown). Thus, the battery 200 can be manually positioned relative to the radio frequency communication rotation device 11, and in particular, the battery 200 can be positioned relative to the rotation axis of the latter.

The conveyor line 100 includes a first conveyor 123 located upstream of the verification device 1000, i.e. between the starting point 121 and the verification device 1000, to bring the stack 120 of objects 201, 202, 203, 204 from the starting point 121 to the verification device 1000, this first conveyor 123 being able to be equipped with an endless belt conveyor 126 (or any other movement device) to ensure the movement of the stack 120 of objects 201, 202, 203, 204 from the starting point 121 to the verification device 1000.The conveyor line 100 includes a second conveyor 124 located downstream of the verification device 1000, i.e. between the verification device 1000 and the arrival point 122, to bring the stack 120 of objects 201, 202, 203, 204 from the verification device 1000 to the arrival point 122, this second conveyor 124 being able to be equipped with an endless belt conveyor 127 (or any other displacement device) to ensure the movement of the stack 120 of objects 201, 202, 203, 204 from the verification device 1000 to the arrival point 122.
