- the method is applied to an automatic or semi-automatic door in the embodiment described in detail.
- operating information of the kinematic chain of the automatic or semi-automatic gate in question is acquired by various means, for example by sensors or by parallel acquisitions of the existing signals.
- the acquisition of information relating to the operation of the driveline is performed on board the rolling stock (onboard mode).
- the acquired operating information is stored and all the processing steps described below are carried out on board.
- the acquired operating information is temporarily stored on board in an on-board storage unit, then transmitted, for example at regular time intervals, for storage in a remote storage unit and processing by a remote system 40, for example in a ground treatment center.
- the steps 54 to 60 described in detail below are in this case performed by the system 40 in a ground processing center, from the operating information received by a communication means.
- the acquisition 52 consists in acquiring several types of information.
- At least one signal is obtained representing the amount of electrical energy consumed during the cycle, for example a current signal and / or a voltage signal consumed during the cycle.
- the signal SC of angular position encoder and / or speed of rotation is also obtained during this acquisition step 52.
- This signal provides change information in the movement, for example accelerations or decelerations, or changes in engine speed.
- the angular position encoder SC signal and / or rotational speed can be used to calculate positions of the opening of the door during the cycle.
- binary information relating to the opening and / or closing and / or locking positions of switches 18 are also received at acquisition step 52.
- the acquisition step 52 is followed by a step 54 of cutting the cycle into a plurality of functional segments, according to the information acquired in the acquisition step 52.
- a cycle of actuation of the kinematic chain between a first position, for example the closed position of the door and a second position, for example the open position starts at a first instant T init of reception of a control signal for opening or opening a given switch of the drive train or for detecting a movement of the motor or the encoder, and ends at a second final instant T, for example given by the reception of a blocking information of the door or by the detection of an end of movement of the motor.
- Cutting 54 consists in cutting the cycle comprised between [T init , final T] into a plurality of functional segments "Segment 1", “Segment 2", ...., "Segment N” as schematically illustrated in FIG. figure 3 .
- Each segment "Segment n" is defined by an initial instant T n-1 and a final instant T n .
- the functional segments have variable durations, each functional segment corresponding to an operating phase of the operating cycle of the door.
- the segments correspond, for example, to successive phases, acceleration of the door, movement of the door at a predetermined speed globally constant and deceleration of the door.
- the clipping is performed using information extracted from the position / velocity encoder signal SC, for example based on changes in engine speed or at specific positions.
- the clipping is performed using the received binary information which indicates various positions of the gate, combined with the information extracted from the position encoder / speed signal SC, for example based on changes in engine speed or on specific positions.
- the signals representative of the amount of electrical energy consumed during the cycle are also used for this division, for example using principles of pattern recognition.
- the detection of an upward or downward initial ramp on the motor current can be used to detect an opening or closing of the gate while a stabilized current phase for a given time can be used to indicate the end of an opening or closing cycle.
- a peak current can determine its acceleration / deceleration, for example when approaching a mechanical stop opening or approaching a locking phase.
- the step 54 of cutting the cycle into functional segments is followed by a step 56 of calculating values of one or more descriptors per functional segment.
- the calculated descriptor values are representative of the electrical energy consumed by the drive train during each functional segment of the operating cycle and / or the duration of each functional segment and / or the positions of the gate.
- the step 56 of calculating descriptors by segment is followed by a step 58 of calculating one or more health indicators (in English, "health indicators") of the door, including the two types of health indicators described. below.
- an overall health indicator is calculated by forming a global vector comprising at least a portion of the descriptor values, followed by calculating a distance, between the global vector and a corresponding reference vector, wherein each descriptor takes a previously stored reference value, for example a value in a so-called healthy state.
- the calculated distance is a statistical distance, for example the Mahalanobis distance.
- the calculated distance is a Euclidean distance.
- Step 58 is followed by a step 60 of establishing a diagnosis of operation.
- This step comprises in particular the detection of degradation, and in the case of degradation detection, the characterization of the degradation, in particular the identification of the type of degradation.
- the characterization of the degradation comprises, in one embodiment, the localization of the degradation, for example the determination of the element or elements of the kinematic chain having a degraded operation, and the estimation of the severity of the degradation.
- the overall health indicator, calculated in step 58 is compared with predetermined performance thresholds. These operating thresholds are determined by a statistical approach based on the requirements in terms of false alarm rate and good detection rate. Degradation is detected when the value of the health indicator exceeds a predetermined threshold of operation.
- An operating report is for example established periodically (step 62) and, in case of detection of significant degradation, an alarm is for example issued in step 62.
- a significant degradation is for example a detected degradation whose estimated severity exceeds a predetermined threshold of severity.
- the method makes it possible to detect degradations before a failure occurs.
- the plurality of functional segments and the plurality of health indicators used it is also possible to identify the type of degradation and to identify the part of the degraded kinematic chain, or the unsatisfied adjustment or the consumable degraded / absent.
- a signature vector is established, including at least a portion of the individual health indicators calculated at step 58.
- the portion of the health indicators to be considered for a type of degradation considered is predetermined.
- a measure of similarity between the signature vector and each of the reference signature vectors is calculated.
- the said reference signature vectors consist of the individual health indicators calculated at step 58 for each stored degradation, for example during a test phase or during a degradation observation, as explained below.
- the identification and location of the degradation then consists in determining which of said reference signature vectors has the greatest similarity with the calculated signature vector.
- the similarity measure performed is a cosine similarity measure.
- the severity of the degradation is defined as the level of degradation achieved between the healthy state and the maximum allowable degradation state.
- the severity of the degradation is defined as a number commonly between the null value and the value 1. The more the value of said severity is close to zero, the weaker or even the non-existent degradation. The higher the value, the more severe the degradation.
- the severity is calculated as the standard of the projection of the signature vector calculated on the reference signature vector for the identified degradation.
- the method then makes it possible to identify, locate and determine the severity of one or more degradations on the door and makes it possible to carry out maintenance more precisely.
- the method makes it possible, by tracking the history of the stored severity values, to determine the probability of failure for a given horizon.
- the maintenance is then performed in time and avoids a failure of the door.
- the method can also be used in an upstream test phase, in particular on a dedicated test bench, before installation, in particular for the calculation of the reference characteristic values in nominal operation or in degraded operation.
- the system also uses the context information 36, which is for example stored in the storage unit 44.
- Context can affect measurement, creating disruptions.
- the sensitivity of the indicators to the context can optionally be tested on a dedicated test bench.
- the context is subsequently called the vector constituted by the set of values of the context information in a situation described.
- the values of the calculated descriptors are recalibrated with respect to the context, for example by a regression method.
- an instance of the diagnostic system is executed for each context class.
- a said context class is defined as a predefined set of context values. For example, the diagnosis of a door can be made from measurements made at a regular interval on a defined location during the journey of the railway vehicle.
- the influence of the context is reduced and the number of false alarms, wrongly indicating a deterioration alarm, is thus reduced.
