- the particular configurations correspond to the following transitions of frame 10 for each step (each pick) of the predefined sequence of positions: - the frame 10 remains stationary in a high position;
- the frame 10 remains stationary in a low position
- the frame 10 initiates a movement from a high position to descend to a lower position (the frame having remained stationary during the previous step);
- the frame 10 initiates a movement from a low position to climb to a higher position (the frame having remained stationary during the previous step);
- the frame 10 continues to move from a high position to descend to a lower position (the frame having already moved in the previous step);
- the frame 10 continues to move from a low position to climb to a higher position (the frame having already moved in the previous step).
- the mechanical stresses exerted during a passage of the frame without stopping from a high position to a low position are not the same as the mechanical stresses exerted during a starting of the frame from the high position, for example. example.
- the recognition of the particular configurations is carried out on the basis of the position of the frames conforming to the weave which is transmitted by the control device 16 of the loom 2 to the control device 14.
- the control device 14 has the desired position of each frame and also the position of each frame in the preceding and following picks. He can thus identify the particular configuration reproduced by each frame.
- the information on the position of the frame 10 is determined by the controller 14 from information on the position of the output components 7 or of the transmission components 8 coupled to the frames 10.
- the movement of the frame 10 is determined automatically from the activation sequence of the electromagnets 40 applied by the control device 14 when it controls the positions of the output levers 7.
- the movement of the frame 10 is extrapolated from a measurement of the effective movement of the output lever 7 thanks to the displacement sensors 38.
- Each strip is associated with counters which each correspond to one of the particular configurations sought.
- the control device 14 updates the counters. These counters are stored here in the maintenance file 30.
- the counters associated with each blade provide information on the intensity with which said blade has been requested during the operation of the machine 4.
- the invention makes it possible to take into account the intensity with which the components of the machine are individually stressed, in particular for the mechanical components involved in the kinematics of transmission of forces.
- information on the state of wear and stress for each frame 10 of the machine is obtained without the need to disclose the armor used to a service provider.
- the control device 14 acquires the measurement of the force in the first transmission rod 8 via the force sensor 36. It conditions this measurement in the form of a maximum force and of an equivalent effort. As the force in the connecting rod is indeed variable, it is necessary to take a significant value for these variations.
- the equivalent force F eq ui is calculated for an armor ratio using the following formula:
- F (t) is the force measured as a function of time
- T is the effort recurrence period (duration of execution of an armor report).
- control device 14 extrapolates these forces to obtain the forces in the other 15 connecting rods on the basis of the frame strokes recorded in the configuration parameters file.
- frame strokes could come from direct measurements or from processing stress measurements.
- the control device 14 takes account of the weave analysis. Indeed, for the same blade the forces corresponding to a passage without stopping from the high position to the low position are not the same as the forces corresponding to a start from the high position.
- the controller 14 collects the measurements of the angular position sensor of the input shaft and performs a derivation with respect to time to obtain the weaving speed, for example in number of picks per minute.
- the weaving speed is also accessible from the control device 16 of the loom as is information concerning the operating mode.
- the control device 14 of the dobby can thus know whether it must take into account the measures to update the counters. It will not take into account, for example, measurements made when the loom is in slow speed running mode.
- control device 14 is further programmed to automatically calculate, for at least some of the components of the textile machine, severity indices defined as the current level of use of the component with respect to a limit. intrinsic to the component.
- this severity index represents the intensity of a request at a given time.
- a load severity index is defined for each component monitored, as being the quotient of the measured (or extrapolated) force undergone by this mechanical component over the load limit of this mechanical component.
- a wear severity index can also be defined for each monitored component, as the quotient of the dynamic load capacity over the product of the equivalent force times the weaving speed.
- a power severity index can be calculated as being the average, over a weave ratio, of the product of the speed of the loom times the torque exerted on the input shaft 6, this mean being divided by a reference value.
- This severity index gives a representation of the energy consumption of the machine 4 with respect to predefined limits.
- indices can be calculated per pick, or for the length of a weave (that is, for a weave ratio).
- an armor severity index can be calculated as the number of times executives, over the duration of an armor report, perform the following actions:
- This number then divided by the product of the ratio of the weave times the number of frames used in the weave.
- This armor severity index locates the number of moves required by the armor relative to the maximum number of moves possible.
- control device 14 is further programmed to automatically compare, for each step of the predefined sequence of positions, the position of each frame 10 of the loom with a reference position imposed by the sequence of positions. predefined. This makes it possible to detect possible false knocks during the weaving.
- control device 14 compares for each blade the position of the frame 10 determined from the sensors 38 with the position of the frame 10 conforming to the weave which is transmitted by the control device 16 of the loom to weave 2 to the controller 14.
- control device 14 is further programmed to automatically calculate, for at least part of the components of the textile machine, a cumulative damage index defined as the state of wear of the component with respect to a reference state.
- a cumulative damage index can be calculated with reference to mechanical links, such as bearings, involved in the transmission kinematic chain associated with each frame 10.
- the joints of the blade are bearings whose life can be estimated by standard models requiring knowledge of operating variables such as the applied force, the range of motion and its frequency. There can also be added parameters related to operating conditions such as temperature, type of lubrication, etc.
- a3 is a life correction factor taking into account operating conditions such as lubrication. It is based on experience and may include variations calculated from the measured oil temperature.
- Vit is the operating speed of the loom in strokes per minute
- Ose is the angle of oscillation during a stroke in degrees
- Each weave report made is comparable to a damage that can be defined as the ratio of the duration of a report to the calculated theoretical life.
- the cumulative amount of this damage constitutes a damage rate and represents a percentage of the theoretical life of the mechanical component.
- the controller 14 also calculates the damage rate of the lubricating oil. Indeed, the oil is subject to aging, the speed of which depends on the temperature of use and the level of stress.
- the control device 14 has an oil temperature measurement and a torque measurement which is representative of the intensity of the stress. For each armor, the controller 14 can calculate a damage rate.
- the control device 14 For each pick, the control device 14 makes comparisons between the maximum measured or extrapolated level of effort and the maximum stress limits of the components. In the event of an overrun, it records this overshoot for the mechanical component concerned and transmits it to the loom 2. For example, for each pick, the control device 14 compares the maximum torque measurement and a value. maximum torque limit tolerable by the dobby. If the controller 14 concludes that it has exceeded 20%, it records the occurrence. If the overshoot is more than 50%, the control device 14 records the occurrence and transmits to the loom a stop request accompanied by an error code which allows the loom to display the appropriate message.
- control device 14 transmits the information, for example via the internet connection, to the remote server 22 which can carry out additional analyzes.
- the remote server 22 can implement more sophisticated models based on the comparison with the efforts collected in comparable applications.
- the control device 14 receives the weave of the loom and its length, that is to say the number of picks called the ratio at the end of which the weaving will continue by resuming the first pick. As soon as it receives the information of a change in armor, the control device 14 begins recording the maximum values of the forces in the first transmission rod 8 and of the torque on the input shaft on ratios successive until these values stabilize, ie for example the difference between the maximum values measured for 5 consecutive reports remains less than 20% of the highest value. The maximum value is recorded as the reference value of the weave ratio.
- the control device 14 compares the maximum torque measurement and the maximum torque reference value of the armor. If it concludes that it has exceeded 20%, it records the occurrence. If the overshoot is more than 50%, it records the occurrence and transmits to the loom 2 a stop request accompanied by an error code which allows the loom 2 to display the appropriate message.
- the control device 14 records the temperature measurements at regular intervals, for example every minute. It calculates a sliding average and as soon as this average stabilizes, it records a stabilized operating state, that is to say, it records in the maintenance file 30 a start time of a stabilized operating period.
- the controller 14 updates counters or damage rates. At the same time, these counters and damage rates are compared to predefined thresholds. Depending on the result of this comparison, a state variable is updated.
- the associated state variable takes the value "RAS” (for "nothing to report", indicating a state that does not require any maintenance intervention) as long as it is less than 80% then the value "to be monitored” while 'it remains below 150% and "to be checked” above.
- the control device 14 is connected to the remote server 22 which has access to all the maintenance data of the dobby in question but also of other dobby of the same weaving or other weaves. Analyzes of this data, which constitute a database, can help refine life prediction models. Thus, the server 22 can compare the operating conditions of the dobby with conditions already recorded and possibly transmit modifications of the model. Using the principle of armor analysis, server 22 only collects data that does not reveal the armor.
- a maintenance schedule can be established. Knowing the damage rates of the various components of the machine makes it possible to consider grouping replacement operations in order to limit production downtime.
- the counters and the damage rates associated with the replaced elements must be initialized.
- the maintenance file 30 must be modified so that the counter or damage rate values are reset to zero. This operation can be performed remotely via an interface in connection with the remote server 22. As a variant, it can be performed via the screen of the loom 2 on an interface in connection with the control device 14 of the dobby.
- the control device 14 has the recording of false hits. Their frequency can reveal a weakness of the electromagnets 40 and justify its replacement.
- the controller 14 can detect variations in speed during the making of a pick. Significant variations indicate weakness in training and may explain abnormal exercise levels for the application.
- the controller 14 transmits the information via the internet connection to the remote server 22 which can carry out additional analyzes.
- additional analyzes make it possible to determine whether these variations are detrimental to the life of the components of the dobby. Indeed, strong variations in speed during the realization of a pick are accompanied by an increase in forces which is not detected if it remains compatible with the maximum stress limit.
- This example can be transposed to other mechanical components of the machine 4, for example by using different sensors and / or theoretical models.
- FIG. 2 represents a second embodiment of the invention in which a weaving loom 102 is associated with a textile machine 104.

- angle sensor 34 is omitted.
- the oil circulating in the lubrication circuit 46 passes through an exchanger subjected to a flow of air sucked by a fan 110 through an air filter January 12.
- the measuring device therefore further comprises a pressure sensor 1 14 disposed upstream of the fan 1 10, here in the air stream between the fan 1 10 and the filter 1 12.
- the pressure sensor 1 14 provides information on the level of clogging of the air filter 1 12.
- a state variable associated with the air filter 1 12 can thus be defined in one of the maintenance files 30 and updated. automatically by the control device 14 by comparing the pressure measurement with one or more predefined reference values.
- the state variable is set at a “normal” level as long as the pressure remains less than or equal to 80% of a reference threshold, at a level “to be monitored” as long as the pressure pressure is between 80% and 150% of the reference threshold, and at a level “to be cleaned” when the pressure exceeds 150% of said threshold.
- the controller performs armor recognition based on the positional information from proximity sensors 38. For each frame used, it reconstructs the sequence of high or low positions occupied by the frame at each pick.
- the frame 10 remains stationary in a low position
- the frame 10 initiates a movement from a high position to descend to a lower position (the frame having remained stationary during the previous step);
- the frame 10 initiates a movement from a low position to climb to a higher position (the frame having remained stationary during the previous step);
- the frame 10 continues to move from a high position to descend to a lower position (the frame having already moved in the previous step);
- the frame 10 continues to move from a low position to climb to a higher position (the frame having already moved in the previous step).
- This information increments counters associated with each blade. Thus, only information is kept for maintenance purposes from which it is not possible to reconstruct the armor. The confidentiality of the application is guaranteed in principle.
- the weaving speed is collected from the loom controller 16 as is information about the operating mode.
- FIG. 3 represents a third embodiment of the invention in which a loom 202 is associated with a textile machine 204.

- each collar 206, 208 induces a displacement of each stringer 212 relative to the tipping board 210.
- the electronic control device 14 is programmed to automatically control the positioning of the collars 206, 208 in a position conforming to a reference position imposed by the armor, while taking into account the angular position of the shaft. entry 6, so that the collars 206, 208 are moved synchronously with the movement of the loom 202.
- each collar 206 is integral with the end of a cord which winds on the lower pulley of a coupling and the other end of which is fixed.
- a second cord comprising a hook at each of its ends is wound around the upper pulley of the coupling.
- the input shaft 6 sets in motion two series of knives capable of driving the hooks in phase opposition.
- the control device 14 controls a device for retaining the hooks, with or without powering the electromagnets. When the two hooks associated with a collar are retained, the collar remains in the high position.
- eight devices for selecting a collar are grouped together in each selection module 218.
- the machine 204 is a Jacquard machine comprising 2688 collars arranged to a depth of sixteen collars.
- a fan 220 provided with an air filter 222 cools the interior of the machine 204.

These treatments are similar to those implemented for the machine 4 but s 'apply for different components.
- the controller 14 has the weave, also called design, in the case of Jacquard weaving.
- the weave does not necessarily come from the loom controller 16 of the loom 202 or from an analysis but resides in a memory of the controller 14 which can then determine for each pick and for each neck whether the neck:

- the invention is not limited to the components detailed in the embodiments and could be applied to other mechanical or electronic components.
- the invention is not limited to the types and location of the given sensors.
- the position of the frames (or snares) at each pick could result from the analysis of an image taken at the frames or at a transmission element. It could also result from the analysis of force signals since each blade or collar would be equipped with a force sensor.
- control devices capable of implementing the various processing operations, some of which are sophisticated and require computing power. Certain calculations such as that of the equivalent effort could be deported to the remote server 22 from the moment when the force signals (or values representative of these force signals) are transferred to the remote server 22.
- the calculation of the reference values of the ratio used in the drift detection can be deported to the remote server 22.
- the invention is applicable to shed forming devices having an input shaft driven directly by an actuator controlled by the control device 14 of the textile machine or by the control device 16 of the loom.
- the input shaft 6 is then coupled to the loom.
- the predefined position sequences refer to two possible positions of the frames or collars.
- the invention is also applicable to three-position weaving in which the position of the frames or collars is either a high position, or an intermediate position, or a low position. These three positions make it possible to create two superimposed crowds for the double tablecloth weaving.
- the particular configurations correspond to the following particular configurations of the frame 10 (or, as the case may be, of the collar) for each step (each pick) of the predefined sequence of movements:
- the frame 10 remains stationary in a low position
- the frame 10 initiates a movement from a high or intermediate position to descend to a lower position (the frame having remained stationary during the previous step);
- the frame 10 initiates a movement from a low or intermediate position to climb to a higher position (the frame having remained stationary during the previous step);
- the frame 10 continues to move from a high or intermediate position to descend to a lower position (the frame having already moved during the previous step);
- the frame 10 continues to move from a low or intermediate position to climb to a higher position (the frame having already moved in the previous step).
- the force applied to the collars can mainly depend on the return of the springs while the dynamic force associated with the movement is negligible.
