Description

Title of the invention: Method for tracking a coating product line, and associated computer program product

[0001] The present invention relates to a method of monitoring a coating product line, in particular a paint line, the coating product line comprising a plurality of equipment.

[0002] The invention further relates to an associated computer program product.

[0003] The use of sensors on equipment to monitor the operation of said equipment is known.

[0004] However, it is then necessary to provide each piece of equipment of interest with the corresponding sensor, in order to have a monitoring of the coating product line.

[0005] However, the line with the set of sensors is then particularly complex and expensive.

[0006] The aim of the invention is therefore to propose a method for monitoring a coating product line which limits the complexity and cost associated with the line.

[0007] To this end, the invention relates to a method for monitoring a coating product line, in particular a paint line, the coating product line comprising a plurality of equipment and at least one sensor, characterized in that at least two pieces of equipment, referred to as identifiable equipment, of the plurality of equipment are each provided with an identification module, each identification module comprising a memory containing a respective identifier, each identification module being capable of communicating the respective identifier, the sensor being adapted to measure at least one parameter of the coating product line at the level of one of the identifiable equipment, referred to as basic equipment, and in that the method comprises the following steps:

[0010] - construction of a virtual model of the coating product line from the identifiers read,

[0011] - receiving data measured by the sensor, and

[0012] - determination, from the measured data, of determined data, the determined data relating to at least one ancillary equipment, the at least one ancillary equipment being one of the identifiable pieces of equipment different from the basic equipment.

[0013] Thus, thanks to a single sensor, information is obtained for a plurality of equipment. This allows for monitoring of the coating line, without requiring a sensor for each piece of equipment of interest.

[0014] According to other advantageous aspects of the invention, the method comprises one or more of the following features, taken individually or in all technically possible combinations:

[0016] - the sensor is adapted to measure the quantity of coating product passing through the basic equipment, the determined data including the quantity of coating product passing through the ancillary equipment, the method including a step of monitoring the cumulative quantity of coating product having passed through the ancillary equipment from the determined data;

[0017] - the monitoring method includes a step of emitting an alert signal when the cumulative quantity of coating product having passed through the ancillary equipment exceeds a threshold;

[0018] - each identification module includes a Communication label in Near Field;

[0019] - the monitoring method includes a maintenance step using a kit of maintenance, the maintenance kit being equipped with an identification module with a respective identifier;

[0020] - The monitoring method comprises the following steps:

[0021] - replacement of identifiable equipment with new equipment, the new equipment being equipped with an identification module with a respective identifier,

[0022] - reading the identifier of the new equipment by the acquisition device, and

[0023] - replacement in the virtual model of the identifiable equipment replaced by the new equipment;

[0024] - the monitoring method includes a data conformity verification step determined with at least one criterion of the ancillary equipment, the criterion including for example a maximum value and / or a minimum value;

[0025] - The monitoring method comprises the following steps:

[0026] - supply of at least one part to be coated, the part to be coated being provided with a identification module with a respective identifier, the coating product line being equipped with a reader adapted to read the identifier of the part to be coated by the coating product line,

[0027] - detection of the identifier of the part to be coated by the reader, and

[0028] - determination of coating parameters of the part to be coated from the data measured.

[0029] The invention also relates to a computer program product, comprising software instructions suitable for, when implemented by computer, implementing the steps of construction, reception and determination of a tracking method as described above.

[0030] The invention will become clearer upon reading the following description, given solely by way of non-limiting example, and made with reference to the drawings in which:

[0031] [Fig-1] [Fig.1] is a schematic representation of a system for the mode of realization of the invention,

[0032] [Fig.2] [Fig.2] is a schematic representation of steps of a method according to a first embodiment of the invention, and

[0033] [Fig.3] [Fig.3] is a schematic representation of steps of a method according to a second embodiment of the invention.

[0034] The invention relates to a method of tracking a line of coating product, in particular paint.

[0035] The coating product is, for example, fluid.

[0036] An example of line 10 is shown in [Fig.1].

[0037] The line shown is a highly simplified example, illustrating a tracking method according to the invention. The line is not limited to the example provided. In particular, a coating product line generally comprises a more complex system.

[0038] Line 10 comprises a plurality of equipment 12, 14, 16, 18, 20 and at least one sensor 22.

[0039] More particularly, here, the line 10 includes a power source 12, a pump 16, a supply path 14 extending between the power source 12 and the pump 16, a coating product application device 20, and a distribution path 18 extending between the pump 16 and the application device 20.

[0040] The plurality of equipment 12, 14, 16, 18, 20 is, for example, arranged in line, in series.

[0041] At least two pieces of equipment, referred to as identifiable equipment, 16, 18, 20 of the plurality of equipment are each provided with an identification module 24, 26, 28.

[0042] Here, the pump 16, the distribution channel 18 and the application device 20 are each provided with an identification module 24, 26, 28.

[0043] Each identification module 24, 26, 28 is, for example, arranged within the corresponding identifiable equipment.

[0044] More specifically, each identification module 24, 26, 28 is not accessible from outside the identifiable equipment.

[0045] Alternatively or additionally, each identification module 24, 26, 28 is fixed on the identifiable equipment, outside.

[0046] Each identification module 24, 26, 28 includes a memory containing a respective identifier. The respective identifier is specific to the identifiable equipment.

[0047] The respective identifier makes it possible, for example, to identify the nature of the equipment corresponding.

[0048] Each identification module 24, 26, 28 is capable of communicating the respective identifier.

[0049] Each identification module 24, 26, 28 includes, for example, an RFID tag, from the English "radio frequency identification" or, in French, radio-identification.

[0050] More specifically, each identification module 24, 26, 28 includes a Near Field Communication or NFC label.

[0051] This allows for remote detection of the desired label.

[0052] The use of the CCP also allows for secure and very select the desired label by approaching the corresponding equipment.

[0053] Each tag includes an antenna adapted for communication and a memory storing the respective identifier.

[0054] Alternatively, one or each identification module 24, 26, 28 includes, for example, a visual identifier, for example a QR code or an alphanumeric identifier, for example the serial number of the identifiable equipment.

[0055] The sensor 22 is adapted to measure at least one parameter of line 10 at the level of one of the identifiable equipment 16, 18, 20, referred to as basic equipment 16.

[0056] The sensor 22 is, for example, suitable for measuring the quantity of coating product passing through the basic equipment 16, for example a pump of line 10.

[0057] The sensor 22 includes, for example, a flow meter.

[0058] The sensor 22 is, for example, suitable for measuring the pump strokes of the pump and calculating the quantity of coating product passing through the pump, here pump 16.

[0059] Additionally or alternatively, the sensor 22 measures the pressure of the coating product passing through the base equipment 16.

[0060] At least one identifiable piece of equipment 18, 20 is devoid of a sensor measuring at least one parameter.

[0061] The basic equipment 16 is connected to at least one auxiliary equipment 20, the auxiliary equipment 20 being one of the identifiable equipment 16, 18, 20 different from the basic equipment 16.

[0062] The ancillary equipment 20 is devoid of a sensor measuring at least one parameter.

[0063] Line 10, for example, lacks a branch between the basic equipment 16 and the ancillary equipment 20.

[0064] Thus, the entire coating product passing through the basic equipment 16 passes, with a temporary offset, through the auxiliary equipment 20.

[0065] In a particular embodiment, the line 10 is provided with a reader 30 adapted to read a respective identifier of an identification module 33 of a part to be coated 32 by the coating product line.

[0066] The reader 30 is, more particularly, adapted to read a respective identifier of a part to be coated 32 arranged opposite an application device 20 of line 10.

[0067] The reader 30 is, for example, arranged upstream of a coating location 36, where the part to be coated is coated with the product of line 10, in a manner adjacent to the coating location 36.

[0068] The parts to be coated are, for example, brought successively by a line of parts 34 to the coating location 36.

[0069] The reader 30 is, for example, arranged opposite the line of parts 34, upstream of the coating location 36, in a manner adjacent to the coating location 36.

[0070] An example of an embodiment of a method for tracking a coating product line will now be described with regard to [Fig.2], illustrated by the example system of [Fig.1].

[0071] The monitoring method 110 comprises the following steps:

[0072] - supply 112 of an acquisition device 50,

[0073] - reading 114 by the acquisition device 50 of the respective identifiers of the identifiable equipment from the coating product line,

[0074] - construction 116 of a virtual model of the coating product line from read identifiers,

[0075] - receiving 118 of data measured by the sensor, and

[0076] - determination 120, from the measured data, of determined data.

[0077] An example of an acquisition device 50, here an electronic device, is shown in [Fig.1].

[0078] The acquisition device 50 is, for example, a portable electronic device.

[0079] The acquisition device 50 includes a reading module 52, adapted to read the respective identifiers of the respective identification modules.

[0080] The reading module 52 is, for example, an RFID reader, more specifically an NFC reader.

[0081] The reading module 52 includes, for example, a radio frequency transceiver, adapted to send a request to an identification module, plus particularly an RFID tag, here NFC, and receive, in response, the identifier of the identification module.

[0082] The acquisition device 50 further includes an information processing unit formed for example of a memory 54 and a processor 56 associated with the memory 54.

[0083] The acquisition device 50 includes, for example, in addition an interface module 58 capable of receiving information from a user.

[0084] The acquisition device 50 here includes a user interface 60, for example a touch screen and / or buttons and / or a sound system.

[0085] The user interface 60 includes, for example, a display device, here the touch screen.

[0086] The interface module 58 is capable of receiving information provided by a user through the user interface 60 and, for example, also of displaying elements on the display device and / or emitting a sound signal through the sound system.

[0087] The acquisition device 50 includes, for example, in addition a communication module 62.

[0088] The communication module 62 is, for example, suitable for enabling communication between the acquisition device 50 and an electronic device 64, for example a computer, more particularly by telecommunication, for example by Bluetooth ®, or by wired connection, or by the mobile telephone network.

[0089] The reading module 52, as well as the optional interface module 58 and / or the communication module 62, are each implemented as software, or a software component, executable by the processor 56. The memory 54 of the electronic acquisition device 50 is then capable of storing reading software, as well as optionally interface software and / or communication software. The processor is then capable of executing each of the software components, including the reading software, as well as the optionally interface software and / or communication software.

[0090] In an alternative not shown, the reading module 52, as well as optionally the interface module 58 and / or the communication module 62, are each made in the form of a programmable logic component, such as an FPGA (Field Programmable Gate Array) or an integrated circuit, such as an ASIC (Application Specified Integrated Circuit).

[0091] When the electronic acquisition device is implemented in the form of one or more software programs, that is to say, in the form of a computer program, also called a computer program product, it is further capable of being recorded on a non-represented, computer-readable medium. The medium is a non- A transient medium, also known as a computer-readable medium, is a device capable of storing electronic instructions and connecting to a computer system bus. Examples include optical discs, magneto-optical discs, ROMs, RAM, any type of non-volatile memory (such as Flash or NVRAM), or magnetic cards. A computer program containing software instructions is then stored on this medium.

[0092] During reading 114, the acquisition device 50 reads, for example successively, all the respective identifiers of the identifiable equipment 16, 18, 20 of line 10.

[0093] More specifically, a user successively approaches the acquisition device 50 of each identifiable equipment 16, 18, 20, so as to allow the reading of the identifier of the identification module 24, 26, 28 of each identifiable equipment 16, 18, 20.

[0094] The acquisition device 50 then stores the read identifiers in its memory 56.

[0095] When the acquisition device 50 reads the identifier of an identification module 24, 26, 28, it emits, for example, a signal indicating to the user the detection, for example a visual signal and / or an audible signal.

[0096] The user then understands that the identifiable equipment has been identified by the acquisition device and then moves to another identifiable equipment, until all the identifiable equipment has been identified.

[0097] In a particular embodiment, when the acquisition device 50 reads the identifier of an identification module 24, 26, 28, the acquisition device 50 displays on the display device one or more pieces of information relating to the corresponding identifiable equipment, for example the nature of the identifiable equipment and / or the corresponding identifier.

[0098] In one embodiment, the display device displays the list of information for all identifiable equipment whose identifier has been read by the acquisition device.

[0099] Alternatively, only the information relating to the last identifiable device whose identifier was read is displayed.

[0100] In a particular embodiment, if several identifiable devices are detected at the same time, then the read identifiers are all saved in memory 56. Alternatively, the acquisition device 50 waits until a single identifiable device is detected at a given time to save the read identifier.

[0101] In a particular embodiment, during the reading step, the method includes a substep of receiving data by the acquisition device relating to the link between identifiable equipment 16, 18, 20 whose identifier is read.

[0102] More specifically, during the reading stage, a user provides, via the user interface 60, information on the link between the identifiable equipment 16, 18, 20 whose identifier is read.

[0103] The data relating to the link between the identifiable equipment 16, 18, 20 whose identifier is read are saved in memory 54.

[0104] In the example shown, the acquisition device 50 reads, for example, the identifier of the pump 16, then that of the distribution line 18. The user then indicates, for example, that the distribution line 18 is connected in series to the pump 16. Then the acquisition device reads the identifier of the application device 20. The user then indicates that the application device 20 is connected in series to the distribution line 18, on the other side with respect to the pump 16.

[0105] Alternatively, the reading step does not include a substep of receiving, by the acquisition device, data relating to the link between the identifiable equipment whose identifier is read.

[0106] Construction step 116 is, for example, implemented by a construction module 66 of an electronic device 64, different from the acquisition device 50.

[0107] Here, the electronic device 64 includes the construction module 66.

[0108] The electronic device 64 further comprises a communication module 68 compatible with the communication technology of the communication module 62 of the acquisition device 50.

[0109] The electronic device 64 includes an information processing unit formed for example of a memory 70 and a processor 72 associated with the memory 70.

[0110] The method then includes a step of transmitting the read identifiers, and where appropriate the data relating to the link between the identifiable equipment 16, 18, 20 whose identifier is read, from the acquisition device 50 to the electronic device 64, via the communication modules 62, 68.

[0111] During construction step 116, a virtual model of line 10 is created from the read identifiers, and where appropriate, data relating to the link between the identifiable equipment 16, 18, 20 whose identifier is read.

[0112] In the absence of data relating to the link between the identifiable equipment 16, 18, 20 whose identifier is read, the identifiable equipment of the line are, for example, considered as connected to each other, in series, more particularly without branching.

[0113] The virtual model of line 10 includes a representation of each identifiable equipment 16 and at least one link between the representations of the identifiable equipment.

[0114] The virtual model includes, for example, mathematical links between elements each representing an identifiable piece of equipment.

[0115] The virtual model of line 10 includes, for example, a table, each identifiable piece of equipment corresponding to a column (alternatively a row), the columns (alternatively the rows) being linked together, for example by mathematical links between cells of the columns (alternatively the rows).

[0116] At least part of the cells represents, for example, a parameter relating to the corresponding identifiable equipment, for example considered at a given time.

[0117] A row (alternatively a column) represents, for example, the same parameter for all identifiable equipment.

[0118] For example, when two identifiable equipment are considered to be connected in a line without branching, then it is considered, for example, that, in the virtual model, at least one cell in each of the columns (alternatively rows) corresponding to said elements are equal to each other, possibly with a temporary offset, more particularly equal to each other for the same row (alternatively column).

[0119] Additionally or alternatively, when two identifiable equipment are considered to be connected in a line without branching, then it is considered, for example, that, in the virtual model, at least one cell in each of the columns (alternatively rows) corresponding to said elements are equal to each other up to a predetermined coefficient, possibly with a temporary offset, more particularly equal to each other up to a predetermined coefficient for the same row (alternatively column).

[0120] The temporary offset here corresponds, for example, to the time for the flow of the coating product from upstream to downstream, between the basic equipment and the auxiliary equipment.

[0121] Alternatively, the coating product line includes at least one Y-branch, comprising two inputs and one output. The line includes, for example, basic equipment at each input and auxiliary equipment after the output. The mathematical relationship is then, for example, an addition, possibly with a temporary offset, and possibly up to a predetermined coefficient.

[0122] Alternatively, the coating product line includes at least one Y-branch, comprising one input and two outputs. The line includes, for example, basic equipment on at least two of the three paths formed by the input and the two outputs, and auxiliary equipment on the other path. The mathematical link is then, for example, an addition or subtraction, possibly with a temporary offset, and possibly up to a predetermined coefficient.

[0123] The virtual model, here the table, is, for example, saved in memory 70.

[0124] The electronic device 64 further includes a receiving module 74, the receiving module 74 being adapted to receive data from at least one sensor 22, the data including measurements of at least one parameter measured by at least one sensor 22.

[0125] During the reception of the measured data, at least part of the measurements acquired by the sensor 22 are received, here by the electronic device 64, here by the receiving module 74.

[0126] The measured data are then, for example, integrated into the table in the column (alternatively the row) corresponding to the identifiable equipment equipped with the sensor 22 which carried out said measurement.

[0127] More specifically, the cells corresponding to the parameter corresponding to the measurements made by the sensor 22 are filled in the table.

[0128] During the determination, determined data are calculated for at least one ancillary equipment from the measured data, for example by a data determination module 75, more particularly of the electronic device 64.

[0129] Here, for example, data are determined for the application device 20 from the data measured by the sensor 22.

[0130] More specifically, through the links between the representations of the identifiable equipment, the data determined from the measured data is calculated.

[0131] For example, the determination includes filling the cells in the table corresponding to the ancillary equipment from the cells corresponding to the basic equipment, through mathematical links.

[0132] The determined data are, for example, equal to the measured data, with a possible time lag, in particular when the auxiliary equipment is connected in line with the basic equipment without branching.

[0133] Alternatively or additionally, considering only a part of the determined data, the determined data are, for example, equal to the multiplication of the measured data by the predetermined coefficient, with a possible time lag.

[0134] Alternatively, the determined data are, for example, equal to an addition or subtraction of measured data, with a possible time offset, and possibly with a multiplication up to a predetermined coefficient, of different basic equipment, in particular when the line has at least one branch between the basic equipment and the ancillary equipment, each of the basic equipment and the ancillary equipment then being on a branch of the branch.

[0135] The data determined include, for example, the quantity of coating product passing through the ancillary equipment, more particularly the volumetric or alternatively mass flow rate.

[0136] Alternatively or additionally, the data determined include, for example, the pressure at the level of the ancillary equipment.

[0137] The monitoring method also includes, optionally, a step of displaying the determined data, and possibly the measured data, by a display device 76 of the electronic device 64.

[0138] The monitoring method also includes, optionally, a step of monitoring the cumulative quantity 124 of coating product that has passed through the ancillary equipment from the data determined, more particularly by a monitoring module 78, for example included in the electronic device 64.

[0139] This allows the use and wear of the ancillary equipment to be monitored.

[0140] The monitoring method then includes, for example, also a step of issuing an alert signal 126 when the cumulative quantity of coating product having passed through the ancillary equipment exceeds a threshold, for example by an alert module 80, here connected to the monitoring module 78, for example included in the electronic device 64.

[0141] The warning signal is, for example, a visual signal, for example an alert on the display device 76, and / or an audible signal.

[0142] This allows for preventative maintenance to be planned.

[0143] The warning signal indicates, for example, the maintenance to be carried out, and for example, a type of maintenance kit to be used depending on the equipment concerned and the maintenance.

[0144] The monitoring method also includes, optionally, a verification step 128 of the conformity of determined data with at least one criterion of the ancillary equipment, the criterion including for example a maximum value and / or a minimum value, for example by a conformity module 82, for example included in the electronic device 64.

[0145] This makes it possible to check whether the ancillary equipment is used in accordance with its intended use, in particular within recommended operating ranges.

[0146] The monitoring method then includes, for example, also a step of issuing an alert signal 130 when the said determined data do not conform to the criterion(a), for example by the alert module 80, here also linked to the compliance module 82.

[0147] More particularly here, the data determined include the pressure at the level of the ancillary equipment, the criterion being, for example, a maximum pressure not to be exceeded at the level of the ancillary equipment.

[0148] Alternatively, the construction steps 116, and / or reception 118 and / or determination 120, and possibly display 122 and / or monitoring of the cumulative quantity 124 and / or issuing of an alert signal 126 and / or verification 128 and / or issuing of an alert signal 130, are directly implemented by corresponding modules of the acquisition device 50.

[0149] In a particular embodiment, the monitoring method includes a maintenance step using a maintenance kit, the maintenance kit being provided with an identification module with a respective identifier.

[0150] The maintenance step includes, for example, reading the identifier corresponding to the maintenance kit, for example by the acquisition device 50 or an acquisition device similar to the acquisition device 50, more particularly the reading module 52.

[0151] The identifier allows, in particular, the type of maintenance kit to be identified.

[0152] The maintenance step then includes, for example, a step of issuing an alert if the maintenance kit does not correspond to the type of maintenance kit to carry out the desired or indicated maintenance following an alert.

[0153] The tracking method includes, for example, a step of transmitting the maintenance kit identifier to the electronic device 64, more particularly via the communication modules 62, 68, and a step of storing said maintenance kit identifier in memory 70.

[0154] This allows in particular for monitoring the maintenance of the equipment on the coating product line.

[0155] This allows, for example, verification that maintenance has been carried out with an appropriate maintenance kit validated by the supplier of the coating product line.

[0156] In a particular embodiment, the monitoring method comprises the following steps:

[0157] - replacement of identifiable equipment with new equipment, the new equipment being equipped with an identification module with a respective identifier,

[0158] - reading of the identifier of the new equipment by the acquisition device or a acquisition device similar to acquisition device 50, more specifically via the reading module,

[0159] - here, transmission of the identifier of the new equipment to the electronic device 64, more specifically via communication modules 62, 68, and here a memorization of said identifier of the new equipment in memory 70, and

[0160] - replacement in the virtual model of the identifiable equipment replaced by the new equipment, more specifically by construction module 66.

[0161] The monitoring method includes, for example, a step of issuing an alert if the new equipment is not a possible replacement for the corresponding identifiable equipment.

[0162] This therefore makes it possible to take into account the possible change of equipment in the coating product line, and in particular for the monitoring of the replaced equipment.

[0163] In the cumulative quantity monitoring step 124, if applicable, the cumulative quantity of coating product that has passed through the ancillary equipment is, for example, reset to zero following the replacement of said ancillary equipment.

[0164] This also allows verification that the replacements were carried out with suitable equipment and validated by the supplier of the coating product line.

[0165] In a particular embodiment, shown in [Fig.3], the monitoring method comprises the following steps:

[0166] - supplying 140 of at least one part to be coated 32, the part to be coated 32 being provided of an identification module 33 with a respective identifier,

[0167] - detection 142 of the respective identifier by reader 30,

[0168] - here, transmission of the identifier by the reader 30 to the electronic device 64, more specifically via the communication module 68, and here a storage of said identifier in memory 70, and

[0169] - determination of coating parameters 144 of the part to be coated 32 from measured data, more particularly by a coating determination module 84, more particularly of the electronic device 64.

[0170] The coating parameters 144 include, for example, the amount of coating product applied to the part to be coated and / or the flow rate of the coating product during the coating of the part to be coated.

[0171] The determination is, for example, carried out from the data measured during the time corresponding to the coating interval of the part, up to a possible temporary offset, the temporary offset corresponding to the time interval for the flow of the coating product between the basic equipment and its coating on the part to be coated 32.

[0172] The method includes, for example, a step of issuing an alert if the coating parameters do not conform to predetermined values, for example by the alert module 80.

[0173] This makes it possible in particular to track the coating parameters with which the different parts to be coated have been coated, and to associate each part with the corresponding parameters.

[0174] In addition, in the event of an error in the coating identified later, this allows for the rapid identification of the parts affected by the error.

[0175] In a particular embodiment, the tracking method further includes a step of saving the determined data, in particular in the "cloud" 90, more particularly of all the data present in the memory 70.

[0176] The construction module 66, the reception module 74, and the data determination module 75, as well as, optionally, the communication module 58, the monitoring module 78, the alert module 80, the compliance module 82, and / or the coating determination module 84, are each implemented as software, or a software component, executable by the processor. The memory of the electronic device 64 is thus capable of storing construction software, data determination software, and reception software, as well as, optionally, communication software, monitoring software, alert software, compliance verification software, and / or coating determination software.
