    Leak detection module and method for checking the tightness of an object to be tested by tracer gas
    The present invention relates to a leak detection module for checking the tightness of an object to be tested by tracer gas and a method for checking the tightness of an object to be tested by tracer gas.
    We know the so-called "sniffing" test and the so-called "spraying" test of tracer gas to check the tightness of an object. These methods involve the detection of the passage of the tracer gas through any leaks from the object to be tested. In sniffing mode, using a leak detector connected to a sniffing probe, one searches for the possible presence of tracer gas around a test object filled with generally pressurized tracer gas. In spraying mode, the tracer gas test object is sprayed with a spray gun, the interior volume of the test object being connected to a leak detector.
    The search for leaks is carried out by moving the sniffing probe or the spray gun around the object to be tested, in particular at the level of the test zones liable to have sealing weaknesses, such as around the seals. seal. An increase in the measured tracer gas concentration signal is indicative of the presence of a leak at the location where the probe tip is positioned. The operator must therefore monitor both the probe and the detector screen. This step is not easy because the screen is generally placed away from the search area, which requires the operator to often turn his head between the detector and the probe.
    This can adversely affect the quality of detection due to the highly reactive nature of the tracer gas. The operator may in fact risk missing a leak detection while he looks away from the screen. One solution is to display a temporal evolution of the measured signal. By viewing the measurement history, the operator can quickly check whether or not a leak has occurred while he was not looking at the screen. A disadvantage is that the operator is not informed in real time of the presence of a leak and must resume his search to locate the missed leak.
    Furthermore, turning the head repeatedly can make the tightness test uncomfortable for the operator, especially in production.
    In addition, when the leak detector is relatively far from the search area and the operator uses a remote screen, the manipulation of this screen requires the immobilization of one hand of the operator, which can be be uncomfortable and inconvenient.
    Another solution consists in emitting a sound of which at least one of the characteristics such as the amplitude, the tone or the pattern, evolves with the concentration of tracer gas measured. This solution allows the operator to know when the probe is approaching a leak without having to look at the detector screen. Part of the information can, however, be lost because the operator's discrimination of sound variations is less precise than reading numerical values.
    Some probes have LEDs that change color with the level of tracer gas concentration. However, as with sound, changing the color can cause information loss.
    Other probes are equipped with dedicated screens, connected to the detectors, displaying the measurement of the tracer gas concentration. However, reading on the probe screen may not always be possible because readability depends on the orientation of the probe and it depends on the accessibility of the test area.
    One of the aims of the present invention is therefore to propose a leak detection module which at least partially resolves the aforementioned drawbacks, in particular by being more ergonomic and easier to handle.
    To this end, the subject of the invention is a leak detection module for checking the tightness of an object to be tested by tracer gas, comprising a leak detector and a probe which can be manipulated by the user, characterized in that that it further comprises a vision device comprising:
    - a processing and display unit configured to communicate with the leak detector,
    - a holding means configured to hold the vision device on the head of a user, and
    a display surface fixed to the holding means to be placed in the field of vision of the user, the processing and display unit being configured to display on the display surface, information relating to the detection of leaks comprising at least one signal representative of the concentration of tracer gas measured by the leak detector.
    The concentration of tracer gas is therefore displayed in the field of vision of the user no matter where he looks. The information displayed thus follows the user's gaze even if the user turns the screen head away from the detector.
    According to one or more characteristics of the leak detection module, taken alone or in combination:
    - the vision device comprises at least one front camera configured to take images in the user's field of vision,the viewing surface includes a screen configured to display images in a portion of the user's field of vision,the viewing surface is formed by a transparent surface allowing the user to see through, the processing and display unit being configured to display in augmented reality at least information relating to the detection of leaksthe processing and display unit comprises a recognition means configured to recognize a test area of the object to be tested and to display on the display surface, a visual cue of the at least one test area,the recognition means is configured to recognize a tip of the probe in the display surface and to detect when the tip of the probe is located in a test area of the object to be tested,the probe is a sniffing probe connected to the leak detector,the probe is a spray gun intended to be connected to a source of tracer gas.
    The subject of the invention is also a method of controlling the tightness of an object to be tested by tracer gas, characterized in that a device for viewing a leak detection module as described above, displays relative information. leak detection comprising at least one signal representative of the tracer gas concentration measured by the leak detector on a display surface placed in the user's field of vision by a vision device worn on the head of a user.
    The signal can be displayed as a numerical value, bar graphs or graph.
    The information displayed may indicate whether the signal exceeds a maximum tracer gas concentration threshold.
    The information displayed may include a signal representative of an operating state of the leak detector, such as an alert or measurement state in progress, a fault, maintenance to be carried out or a recommendation for use.
    At least one predetermined test area of the object to be tested can be recognized by a recognition unit of the processing unit which indicates the test area by displaying in augmented reality, a visual cue on the display surface. The mark may be accompanied by the display of at least one maximum tracer gas concentration threshold associated with the predetermined test area of the object to be tested.
    The processing unit recognition means can detect when the probe tip is located in a test area of the object to be tested.
    You can indicate the test areas that have been tested by the probe.
    The measured tracer gas concentration values associated with the test areas can be recorded. The sequence of measurement operations performed by the user on the object to be tested can be filmed. You can take one or more photos of the probe positioned in the test areas of the object to be tested.

    In these figures, identical elements have the same reference numbers. The following embodiments are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference relates to the same embodiment, or that the characteristics apply only to a single embodiment. Simple features of different embodiments can also be combined to provide other embodiments.
    We define by "object to be tested", an object or an installation whose tightness we want to check.
    Figure 1 shows an example of a leak detection module 1 for checking the tightness of an object to be tested by tracer gas used by a user 5.
    The leak detection module 1 comprises a vision device 2, a leak detector 3 and a probe 4.
    The leak detector 3 comprises for example and as shown in FIG. 2, a detection input 6, a pumping device 7 and a gas detector 8.
    The pumping device 7 comprises for example at least one primary vacuum pump 9, such as a membrane pump, and at least one turbomolecular vacuum pump 10.
    The gas detector 8 is connected to the turbomolecular vacuum pump 10, for example at its suction. The gas detector 8 comprises for example a mass spectrometer. The gas detector 8 makes it possible in particular to determine a concentration in tracer gas of the gases sampled at the detection input 6.
    The outlet of the turbomolecular vacuum pump 10 is connected to the inlet of the primary vacuum pump 9 via a first isolation valve 11.
    The detection input 6 of the leak detector 3 is for example connected to an intermediate stage of the turbomolecular vacuum pump 10, via at least one sampling valve 12a, 12b. The pumping device 7 comprises for example at least two sampling valves 12a, 12b, each valve 12a, 12b being connected to an intermediate stage distinct from the turbomolecular vacuum pump 10 so as to be able to adapt the sampling flow to the level leakage, the sampling valve 12a, 12b being connected to a branch of a pipe of the vacuum line arranged between the detection input 6 and a second isolation valve 13. The second isolation valve 13 is connected at the vacuum line between the first isolation valve 11 and the inlet of the primary vacuum pump 9.
    The probe 4 has a gripping means allowing it to be manipulated by the user 5.
    In the first embodiment illustrated in Figure 1, the probe 4 is a sniffing probe.
    The sniffing probe is connected to the detection input 6 of the leak detector 3 by a flexible pipe 14 so as to draw the surrounding gases from the test object filled with tracer gas. Part of the gases sucked in by the pumping device 7 is analyzed by the gas detector 8 which supplies a concentration of tracer gas to a control unit 21 of the detector 3. The exceeding of a maximum tracer gas threshold is indicative of a leak. Helium or hydrogen are generally used as a tracer gas because these gases pass through small leaks more easily than other gases, due to the small size of their molecule and their high speed of movement.
    The vision device 2 is carried by the head of the user 5.
    As can best be seen in Figure 3, the vision device 2 comprises a processing and display unit 15, a holding means 16 and a display surface 17 (Figure 3).
    The holding means 16 is configured to hold the vision device 2 on the head of the user 5. It comprises for example a frame intended to rest on the nose of the user and to rest on his ears, such as a spectacle frame, or comprises an adjustable hoop around the head of the user 5 or a helmet a support forming a headband.
    The viewing surface 17 is fixed to the holding means 16 so that it can be placed in the user's field of vision 5.
    According to an exemplary embodiment, the viewing surface 17 comprises a screen configured to display images in a portion of the user's field of vision. The vision device 2 may further include a transparent protective surface 20, made of glass or plastic, located between the eyes of the user 5 and the screen, forming glasses.
    The processing and display unit 15 comprises one or more controllers or processors in particular configured to communicate with a leak detector 3. It comprises for example wireless communication means, such as WIFI or Bluetooth, configured to communicate without links wired with complementary communication means of the control unit 21 of the leak detector 3. The processing and display unit 15 can thus access information relating to the detection of leaks. The processing and display unit 15 is for example carried by the holding means 16, such as by a branch of the holding means 16.
    The processing and display unit 15 is further configured to display, on the display surface 17, information 18 relating to the detection of leaks.
    Information 18 includes at least one signal representative of the concentration of tracer gas measured by the leak detector 3 (Figure 4). The concentration of tracer gas is therefore displayed in the field of vision of user 5 no matter where he looks. The information 18 displayed thus follows the gaze of the user 5 even if he turns the head of the screen from the detector 3.
    The signal can be displayed in different ways according to the wishes of the user 5. The signal is for example displayed in the form of a numerical value (Figure 4), bar graphs (intensity graph bars) or a graph.
    The information 18 displayed may indicate whether the signal exceeds a maximum tracer gas concentration threshold, for example using a color code. The signal can thus change color when the concentration of tracer gas crosses a detection threshold. For example, it is displayed in green when the measurement is below the threshold and in red when the measurement crosses the threshold.
    The information 18 may include a signal representative of an operating state of the leak detector 3, such as an alert or measurement state in progress, a fault, maintenance to be carried out or a recommendation for use. The information 18 of the operating state of the leak detector 3 allows for example the user who cannot directly view the leak detector 3, to make sure that he is indeed making a measurement to conclude the absence of leaks in the presence of a weak or zero measurement signal.
    Information 18 can also be displayed in addition on a computer or tablet screen or can be displayed directly on the test object 19 via a projector.
    According to an exemplary embodiment, the vision device 2 comprises at least one front camera 22 configured to take images in the field of vision of the user 5. It is thus possible to film the sequence of measurement operations performed by the user 5 on the object to be tested 19 or to take one or more photos of the test carried out, for example to associate it with a file of tracer gas concentration measurements. A tightness certificate associated with the object to be tested 19 can thus be provided to a customer or to a quality service, this certificate proving on the one hand, that the test zones have indeed been tested by the user 5 and on the other hand, that the sealing level is below the rejection threshold.
    We will now describe an example of operation of the leak detection module 1 and of the associated method for checking the tightness of a test object 19 by tracer gas.
    The test object 19 is previously filled with tracer gas, for example pressurized.
    The user 5 places the vision device 2 on his head to see the viewing surface 17 in his field of vision.
    The user approaches the sniffer probe 4 to a test area.
    The probe 4 connected to the leak detector 3 sucks the surrounding gases from the test object 19 in the test area. A part of the gases thus sampled, possibly containing the tracer gas revealing a leak, is then analyzed by the gas analyzer 8 which provides a measurement of the tracer gas concentration to the control unit 21 of the leak detector 3 The control unit 21 sends this information, processed or not, to the processing and display unit 15. The processing and display unit 15 displays this information 18 for example in the form of a digital value on the viewing surface 17 (Figure 4).
    The information 18 of the measurement of the tracer gas concentration is thus displayed in real time in the field of vision of the user 5. The user 5 thus has access to the measurement without the need to look away from the area without having to hold a remote screen.
    The measured tracer gas concentration values and the associated sequence of measurement operations carried out by the user 5 can be recorded. The sequence of measurement operations carried out by the user 5 on the test object 19 can be filmed by the front camera 22 or the front camera 22 can take one or more photos of the test carried out on the test object 19, in particular probe 4 positioned in the test areas. These results can be associated with serial numbers of the objects to be tested 19, which is particularly useful in production. This centralizes all the results and allows the user to return to a test carried out later.
    Figure 5 illustrates a second embodiment of the vision device 2.
    This second embodiment differs from the previous one in that the processing and display unit 15 is configured to display in augmented reality at least one item of information 24 relating to the detection of leaks on the display surface 23. Augmented reality allows the user to see the information 24 relating to the detection of leaks, superimposed on the real.
    The viewing surface 23 is formed by a transparent surface allowing the user to see through, such as a glass or plastic surface.
    The processing and display unit 15 can also comprise a recognition means configured to recognize at least one test area of a test object 19 and to display information 24 comprising a marker on the display surface 23. visual of the at least one test area (Figure 6).
    The visual mark of the test area can be a location of a surface of the object to be tested or a path to be followed by the probe 4.
    For this, for example, a spatial representation of the object to be tested in 3D is stored, for example in the form of a file, as well as at least one reference frame associated with the object to be tested.
    The reference mark makes it possible to associate the object to be tested with the information to be displayed on the display surface 23. It is for example a barcode or a photograph of the object to be tested. In the case of a barcode type reference frame, the same reference frame is placed on the object to be tested.
    The recognition means is for example configured to perform image processing in particular to compare the images taken by the front camera 22 of the vision device 2 carried by the user 5 looking at the object to be tested with the spatial representation of the memorized test object. The processing unit 15 searches for the reference mark in the images taken by the front camera 22. In the case of a reference mark of barcode type, once the reference mark is recognized, the spatial representation is selected. match with the pictures. In the case of a photo-type reference frame, the object to be tested is recognized directly in the images taken by the front camera 22 and an attempt is made to match the spatial representation with the images.
    This calibration step allows the information displayed in augmented reality to "follow" the object to be tested seen through the display surface 23.
    According to another example, provision can be made for the object to be tested 19 to be placed by the user 5 in a known spatial reference so that the recognition means can identify the test area of the object to be tested in the surface of display 23 with light image processing.
    Three predetermined test areas of the test object 19 are thus indicated by a respective visual reference in the information 24 displayed in augmented reality in the example of FIG. 6.
    In addition to the visual cue, information 24 may include at least a maximum tracer gas concentration threshold associated with the test area. The threshold can be different depending on the test area (Figure 6).
    The recognition means of the processing and display unit 15 can also be configured to recognize a tip of the probe 4 in the display surface 23 and to detect when the tip of the probe 4 is located in an area for testing the object to be tested 19. As previously, the recognition means can identify the tip of the probe 4 by image processing. The tip of the probe 4 may have a marker or a color allowing it to be easily identifiable by the means of recognition of the processing and display unit 15.
    The processing and display unit 15 can for example be configured to inhibit a measurement until the tip of the probe 4 is not detected in the test area or can inform the user, for example by a signal audible, when probe 4 is detected in the test area. This can avoid any erroneous conclusions from leakage tests linked to incorrect positioning of the probe 4.
    The information 24 displayed on the display surface 23 can indicate the test areas which have been tested by the probe 4, for example using a color code and for example by leaving displayed in augmented reality a signal representative of the concentration of tracer gas in the test areas that have been tested.
    It is thus possible for the user 5 to quickly see where the test zones are, what are the associated maximum thresholds, which zones have already been tested and which remain to be tested as well as a general state of the rate of leak of the test object 19. The quality of the control is improved by reducing the risk of forgetting the test zones and the duration of the test is reduced by avoiding the user wasting time locating the test zones.
    The measured tracer gas concentration values can be saved.
    The front camera 22 can also film the sequence of measurement operations carried out by the user 5 on the object to be tested, showing the circuit taken by the probe 4 or take one or more photos of the probe 4 positioned in areas test object 19.
    In operation, according to an example of implementation:
    The test object 19 is previously filled with tracer gas. The user 5 places the vision device 2 on his head to see in front of him through the viewing surface 23 positioned in his field of vision.
    The processing and display unit 15 of the vision device 2 indicates to the user 5 the test zones of the object to be tested 19 by the display in augmented reality of the visual cues and the concentration thresholds of tracer gas. maximum associated on the viewing surface 23 (Figure 6).
    The user approaches probe 4 to a test area.
    The processing and display unit 15 recognizes the tip of the probe 4 in the display surface 23 and detects when the tip of the probe 4 has reached a test area. It informs the user 5 of the correct positioning of the probe 4, for example by an audible signal.
    The sniffing probe 4 connected to the leak detector 3 sucks the gases surrounding the test object 19 into the test zone. A part of the gases thus sampled, possibly containing the tracer gas revealing a leak, is then analyzed by the gas analyzer 8 which provides a measurement of the tracer gas concentration to the control unit 21 of the leak detector 3 The control unit 21 sends this information, processed or not, to the processing and display unit 15.
    The processing and display unit 15 displays the information 24 in augmented reality, for example in the form of a digital value, on the display surface 23 (FIG. 7).
    The information 24 is thus displayed in real time in the field of vision of the user 5. The user 5 thus has access to the measurement without the need to look away from the test area and without having to hold a screen deported.
    Once the measurement has been made, for example after the expiration of a predefined duration in the test area or after activation of a switch by the user 5, it can be indicated that the test area has been tested by probe 4. For this, the signal representative of the concentration of tracer gas can be displayed in green or red depending on the measurement result.
    The user 5 can then go to the next test zone and so on until all the test zones are tested, that is to say for example are all associated with the augmented reality display d '' a signal representative of the measured tracer gas concentration.
    Figure 8 shows an example of how to check the tightness of an object to be tested by spraying.
    In this example, the probe 25 is a spray gun connected to a source of tracer gas 26 so as to blow tracer gas around the test object 19 connected to the detection input 6 of the leak detector 3.
    In operation, as before, the user 5 places the vision device 2 on his head to see in front of him through the viewing surface 17, 23 then positioned in his field of vision.
    According to an example of operation, the means for recognizing the processing and display unit 15 of the vision device 2 recognizes the test object 19 previously stored. The processing unit 15 then indicates for example to the user 5 the predetermined test zones of the object to be tested 19 by the display in augmented reality of the visual cues and of the maximum tracer gas concentration thresholds associated on the surface. display 17, 23.
    The user approaches the probe 25 of a test zone. The recognition means of the processing and display unit 15 can recognize the tip of the probe 25 and detect when the tip of the probe 25 is located in a test area of the object to be tested 19. It informs the user 5 of the correct positioning of the probe 25 for example by an audible signal.
    The user sprinkles tracer gas around the object to be tested. A portion of the gases sampled by the pumping device 7 of the leak detector 3, possibly containing the tracer gas revealing a leak, is then analyzed by the gas analyzer 8 which provides a measurement of the tracer gas concentration at the the control unit 21 of the leak detector 3. The control unit 21 sends this information to the processing and display unit 15.
    The processing and display unit 15 displays this information 18, 24 for example in the form of a numerical value, on the display surface 17, 23.
    The information associated with leak detection is thus displayed in real time in the user's field of vision 5 (Figure 9). User 5 thus has access to the measurement without having to look away from the test area and without having to hold a remote screen.
    Once the measurement has been made, for example after the expiration of a predefined duration in the test area, the information 18, 24 indicates that the test area has been tested, for example by displaying the signal representative of the concentration of tracer gas in reality increased at the level of the test zone.
    The user 5 can then go to the next test area and so on until all the test areas are tested, that is to say are all for example associated with the augmented reality display d '' a signal representative of the measured tracer gas concentration.
