[0045] The solution proposed in this application can more accurately indicate the defective areas in the tire, thereby enabling more accurate and efficient location of the defective areas that need to be re-inspected in the tire re-inspection process, reducing the difficulty of re-inspection.

[0046] The embodiments of this application are described below with reference to the accompanying drawings. The terminology used in the implementation section of this application is only for explaining specific embodiments and is not intended to limit the application. Those skilled in the art will recognize that, with technological advancements and the emergence of new scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, so that a process, method, system, product, or apparatus that comprises a series of elements is not necessarily limited to those elements, but may include other elements not explicitly listed or inherent to those processes, methods, products, or apparatuses.

[0048] The tire defect indication system provided in this application will be described below.

[0049] like Figure 1 This diagram illustrates a component architecture of the tire defect indication system provided in this application.

[0050] Depend on Figure 1 It can be seen that the tire defect indication system includes:

[0051] Testing station 10;

[0052] The tire support assembly 11, which is installed on the testing platform 10, is used to support the tire on the target plane;

[0053] At least one indicator light group is provided on the testing station 10, and each indicator light group includes at least one indicator light 12 arranged in a ring;

[0054] And a control device 13 that is electrically connected to each indicator light group.

[0055] The target plane is the plane on which the tire support assembly supports the tire, and its specific configuration depends on how the tire support assembly is positioned relative to the testing platform. For example, the target plane may have a target angle with the testing platform.

[0056] In particular, in order to facilitate tire inspection personnel to check different areas of the tire and to maintain the tire's stability, the target plane can be a horizontal plane or a vertical plane.

[0057] When the target plane is a vertical plane, the tire support assembly can support the tire in a vertical position, at which point the tire's central axis is parallel to the test bench surface. The tire's central axis is a perpendicular line passing through the center of the annulus containing the tire's crown. For easier understanding, please refer to... Figure 2 ,exist Figure 2 This is an example diagram showing how a tire support assembly supports the tire in a vertical plane. Figure 2As can be seen, the tire is placed vertically at this time, and the tire is on a vertical plane. At this time, the central axis of the tire is parallel to the surface of the test platform.

[0058] Similarly, the tire support assembly can also support the tire in a horizontal position, in which case the tire's central axis is perpendicular to the test bench surface.

[0059] In this application, the indicator lights in the indicator light group are arranged in a circular pattern, for example, in Figure 1 Each small dot represents an indicator light (12). Figure 1 As an example, this example assumes each indicator light group comprises 12 indicator lights. The innermost 12 indicator lights form the smallest ring, and the rings expand outwards layer by layer. The indicator lights on each layer of the ring belong to the same indicator light group. Figure 1 The example shown uses seven rings formed by multiple indicator lights. Therefore, in Figure 1 It includes 7 indicator light groups, each of which consists of indicator lights on a single ring, and different indicator lights correspond to different rings.

[0060] In this application, in order for the indicator lights to indicate defective areas on the tire, when the tire support assembly supports the tire on the target plane, the ring formed by at least one indicator light in the indicator light group is parallel to the ring formed by the tire crown. Based on this, when the tire support assembly supports the tire on the target plane, the plane on which each indicator light group is located is parallel to the target plane, such that the ring formed by each indicator light in each indicator light group is parallel to the tire crown.

[0061] For easier understanding, please refer to Figure 2 ,Depend on Figure 2 It is evident that when the tire support assembly 11 supports the tire 20 in a vertical plane, the ring formed by the indicator lights in each indicator light group is also in a vertical plane. In this case, the ring formed by the indicator lights in each indicator light group is necessarily parallel to the ring containing the tire crown.

[0062] In this application, the control device 13 is used to obtain tire defect information, which includes: defect location information of at least one defect area in the tire; based on the defect location information of the defect area in the tire, control at least one target indicator light in the indicator light group to illuminate to indicate the defect area.

[0063] For example, for each defective area in a tire, at least one target indicator light in the indicator light group can be identified whose distance from the defective area meets a set requirement, and then the target indicator light can be controlled to illuminate. The set requirement can be various, such as being the closest to the defective area; being among the top two in order of distance from the defective area (from smallest to largest); or being less than a set threshold.

[0064] The distance between the indicator light and the defect area can be the relative distance between the indicator light and the defect area. For example, this relative distance can be the straight-line distance from the indicator light to the defect area, or the relative offset angle of the defect area relative to the line connecting the defect area and the center of the tire (which is also the center of the tire's crown ring). Based on this, the relative distance between the indicator light and the tire's defect area in the indicator light group can characterize whether the indicator light is suitable for indicating the defect area.

[0065] In this application, the control device can be a host computer or other device with data processing capabilities, without limitation.

[0066] Research has shown that after detecting tire defects, the defective areas can be marked on the tire with a marker or other marking pen for secondary inspection during subsequent tire re-inspections. However, this method can contaminate or damage the tire surface. To protect the tire and ensure the traceability of defect information, tire defect data (such as defect type and location) is currently recorded and stored. However, during tire re-inspection, manual querying of the recorded defect data in the database is required, and the defective areas on the tire must be located based on this data. This method is difficult and time-consuming, and is not conducive to efficiently locating tire defects.

[0067] In this application, when the tire support assembly supports the tire on the target plane, the ring formed by the indicator lights in the indicator light group is parallel to the ring containing the tire crown, allowing the indicator lights in the indicator light group to present an effect similar to the distribution around the tire crown. Based on this, the control device can control at least one target indicator light in the indicator light group to illuminate based on the defect location information of the defect area in the tire. The illumination of the target indicator light indicates the defect area of ​​the tire, enabling tire inspection personnel to quickly and accurately locate the defect area in the tire based on the illuminated target indicator light, thus improving the efficiency of tire defect area location.

[0068] In this application, the specific structural form of the tire support assembly can be varied, as long as it can stably support the tire, and there are no restrictions on this.

[0069] In one possible implementation, to allow the tire support assembly to fit more closely to the tire crown, thereby providing more stable support for the tire, such as... Figure 1 As shown, the tire support assembly may include two parallel support shafts, accommodating tires of various sizes. The support shafts can be fixed to the test bench surface using stainless steel bearings. For example, each support shaft can be a cylindrical shaft with a diameter of 8-10 cm and a length of 50-60 cm.

[0070] The support shaft can be made of rubber and has anti-slip texture on its surface to prevent the tire from slipping.

[0071] The support shaft can be a fixed shaft that cannot be rotated.

[0072] Specifically, to facilitate tire inspection by allowing inspectors to rotate the tire to check its different positions, the support shaft can also be a rotatable roller. For example, rotating the tire can cause the support shaft to rotate, making tire rotation easier. Alternatively, the two support shafts of the tire support frame can be connected to a manual lever; rotating the lever can rotate the support shaft, which in turn rotates the tire it supports.

[0073] In any embodiment of this application, if the tire defect indication system has only one indicator light group, a target indicator light group that needs to be illuminated can be determined based on the defect location information of the defect area, and the target indicator light group can be controlled to be illuminated. For example, if a target indicator light in the indicator light group is determined whose distance from the tire defect area meets a set requirement (e.g., the distance to the defect area is the closest), the target indicator light can be controlled to be illuminated. Based on this, based on the illuminated target indicator light, the inspection personnel only need to locate the defect in the area of ​​the tire close to the target indicator light.

[0074] If the tire defect indication system includes multiple indicator light groups, the application can control the illumination of the target indicator light in several ways:

[0075] For example, if there are multiple indicator light groups, this application can control at least one target indicator light group in each indicator light group to light up based on the defect location information of the defect area. For example, the target indicator light in each indicator light group whose distance from the defect area meets the requirements can be determined, and the target indicator light in each indicator light group can be controlled to light up.

[0076] For example, a target indicator light group can be randomly selected from multiple indicator light groups, and at least one target indicator light in the target indicator light group can be controlled to light up based on the defect location information of the defect area to indicate the defect area.

[0077] In one possible implementation, considering that different tire models have different outer and inner diameters, in order to avoid the situation where the indicator lights in the tire-obstructed indicator light group are blocked and the illuminated target indicator light cannot effectively indicate the defect area, in this application, the control device can also determine the target indicator light group from the indicator light group based on the tire model information.

[0078] Based on this, the control device is also used to obtain tire model information, which is used to characterize the outer diameter or inner diameter of the tire; and based on the tire model information, to determine a target indicator group from the at least one indicator group whose ring diameter of the ring formed by each indicator is matched with the outer diameter or inner diameter.

[0079] Accordingly, when controlling the target indicator light to illuminate, the control device is specifically used to determine, based on the defect location information of the defect area, at least one target indicator light in the target indicator light group whose distance from the defect area meets the set requirements, and control the target indicator light to illuminate.

[0080] Among these possibilities, there are several ways to match the diameter of the ring formed by the indicator lights in the target indicator light group with the outer or inner diameter of the tire:

[0081] For example, the diameter of the ring formed by the indicator lights in the target indicator light group is larger than the outer diameter of the tire, or smaller than the inner diameter.

[0082] For example, the target indicator light group is an indicator light group in which the diameter of the ring formed by the indicator lights is greater than the outer diameter of the tire and is closest to that outer diameter. Alternatively, the target indicator light group is an indicator light group in which the diameter of the ring formed by the indicator lights is smaller than the inner diameter of the tire and is closest to that inner diameter.

[0083] Of course, there are other possibilities for determining the target indicator light group, which will not be elaborated here.

[0084] Understandably, selecting a target indicator light group whose diameter matches the outer or inner diameter of the ring formed by the indicator lights, based on the tire model information, can prevent the indicator lights within the target indicator light group from being obscured by the tire, thus avoiding situations where the illuminated indicator lights cannot effectively guide the tire's defective areas. Furthermore, by considering the location of the defective area, identifying at least one target indicator light group from the target indicator light group that is at a distance from the defective area that meets the set requirements, can more reliably determine the target indicator lights that can indicate the defective area, thereby providing more accurate indication of the defective area on the tire.

[0085] In this application, the control device may obtain tire model information and tire defect information in various ways, without any specific limitation.

[0086] For example, tire model information can be input by the user or pre-configured. Similarly, tire defect information can be pre-stored in a designated database, cloud platform, or the internal memory of the control device, or it can be uploaded to the control device in real time.

[0087] In one possible implementation, considering that different tires may need to be re-inspected at different times, and the number of tires requiring re-inspection may be large, in order to obtain one or more of the tire model information and defect information more efficiently, the tire defect indication system in this application further includes: a marking scanner connected to the control device.

[0088] This label scanner is used to scan tire marking information. This tire marking information uniquely identifies the tire. For example, the tire marking information can be a barcode or tire number. The label scanner can be a barcode scanner, which can scan the tire's barcode or tire number; there are no specific restrictions.

[0089] The marking scanner can be electrically connected to the control device via a USB or Type-C interface, without any specific restrictions.

[0090] Correspondingly, the control device is used to obtain tire defect information and / or model information based on the tire marking information scanned by the marking scanner.

[0091] For example, a designated database or the data storage area of ​​a tire defect detection system can pre-store defect information and tire model information corresponding to different tire markings. Based on this, after the marking scanner scans the tire marking information, it can send the scanned tire marking information to the control device. The control device can then query the designated database or data storage area to retrieve one or both of the tire defect information and model information corresponding to the currently scanned tire marking information.

[0092] Understandably, this is to enable tire inspectors to quickly and intuitively understand information about defective areas on the tire, such as... Figure 1 As shown, the tire defect indication system may further include a display device 14 connected to the control device. For example, the display device can be connected to the control device via data cables and signal cables.

[0093] The display device is used to display defect information of the tire.

[0094] The display device can be installed on the side of the testing table or on a support frame outside the testing table, without any restrictions.

[0095] The size and resolution of the display device can be set according to actual needs. For example, the display device can be a touch screen with a size of 19-21 inches and a resolution of 1920. 1080p allows for the simultaneous display of preview images corresponding to multiple defect areas of a tire.

[0096] Furthermore, in order to enable the re-inspection personnel to more intuitively understand the specific location and morphology of the defective areas of the tire, in this application, the defect information obtained by the control device includes not only the defect location information of each defective area, but also at least one local tire image corresponding to each defective area, in which the defective area is marked.

[0097] Correspondingly, the control device is also used to determine the target defect area to be displayed from at least one defect area, and output the local tire image corresponding to the target defect area and the defect location information of the target defect area to the display device.

[0098] Based on this, since the display device can output a partial tire image of the target defect area that needs to be displayed on the tire, as well as the defect location information of the target defect area, and the defect area is also marked in the partial tire image of the target defect area, the inspection personnel can intuitively see the image of the target defect area in the tire through the display device, and can understand the defect type, shape and size of the defect area and other information visible to the naked eye. On this basis, combined with the defect location information of the target defect area displayed on the display device and the illuminated target indicator light, the target defect area in the tire can be located more efficiently.

[0099] In one possible implementation, in order to more accurately and efficiently locate defective areas in the tire, in any embodiment of this application, the defect location information of the defective area can be the relative location information of the defective area relative to the target identification area in the tire. The target identification area can be an identification area on the tire used to display or affix tire identification information (such as tire entry or tire number); it can also be other unique and visually identifiable areas, without limitation.

[0100] Based on this, the display device can show the relative position information of the defect area relative to the target marking area on the tire, so that the inspection personnel can accurately and quickly locate the defect area according to the guidance of the defect area and the target indicator light.

[0101] Furthermore, considering that the tire is a circular ring, in order for the relative position information of the defect area relative to the target marking area to intuitively reflect the position of the defect area on the tire, this relative position information can be the relative deviation angle of the defect area relative to the target marking area. This relative deviation angle is the rotation angle required from the target marking area in the tire to the defect area.

[0102] The relative deviation angle can be a specific angle value. Specifically, to allow users to more intuitively locate the defect area, the tire can be used as a clock face. Correspondingly, with the target marking area as the 12 o'clock position, the relative deviation angle can be relative to the clock direction. For example, if the relative deviation angle is 90 degrees, then the defect area can be located at the 3 o'clock position relative to the target marking area.

[0103] Furthermore, considering that a tire has multiple tire parts, in order to more efficiently locate defective areas within the tire, in any of the above embodiments of this application, the defect information of the defective area may also include the tire part where the defective area is located. For example, the tire parts may include, but are not limited to, the tire crown, tire sidewall, tire shoulder, and tire lining. Of course, the tire sidewall may be further subdivided into a first sidewall on the same side as the target marking area and a second sidewall on a different side from the target marking area, etc., without any specific limitations.

[0104] Of course, in practical applications, the defect information of the defect area can also include one or more of the following: defect type, area, diameter, length, and width. The defect type can be categorized as follows: cracks, holes, or wear, etc., and can be set as needed.

[0105] To facilitate understanding, and to illustrate the benefits of locating tire defect areas using defect information displayed on a screen, the following section will discuss... Figure 3 and Figure 4 Please provide an explanation.

[0106] Figure 3 The display interface of the device shows a list area 301 on the right, displaying preview images of multiple defect areas to be shown. After selecting a preview image of the target defect area from the list area, a partial tire image of the target defect area is displayed in the image display area 302 of the display interface. The target defect area on the tire is marked with a box in this partial tire image. The defect information of the target defect area is displayed in the data display area 303 on the right side of the display interface. This defect information includes at least the tire location of the target defect area and the defect's position. Figure 3Taking the defect location information as an example, the relative deviation angle of the defect information relative to the target marking area on the tire is used, and the clock direction is used to represent the relative deviation angle.

[0107] like Figure 3 As shown, the target defect area is located on the tire crown, and is positioned at the 3 o'clock position relative to the target marking area (located at the 12 o'clock position). This defect information also includes details such as the area, diameter, and width of the target defect area.

[0108] exist Figure 3 Based on this, after determining the target indicator light group based on the tire model information, the control device can determine the target indicator light group closest to the target defect area based on the relative deviation angle between the target defect area and the marking area, and control the illumination of that target indicator light. For example... Figure 4 As shown, when the inspector places the tire 20 onto the tire support assembly 11, the target marking area 401 of the tire 20 can be kept directly above it. Therefore, if the tire is considered a clock face, the target marking area 401 is located at the 12 o'clock position on the clock face, while the different indicator lights 12 are located at different clock positions on the clock face. Based on this, the control device can control the target indicator light 121 located at the 3 o'clock position in the target indicator light group to illuminate. Combined with... Figure 3 and Figure 4 It can be seen that, based on the defect information of the target defect area displayed on the display device, and in conjunction with the target indicator light, the re-inspection personnel can accurately locate the target defect area from the tire crown.

[0109] Understandably, in tire inspection areas such as workshops, inspectors often need to stand and may wear gloves to facilitate tire inspection. Therefore, it may not be convenient for them to operate input devices such as mice by hand. Based on this, to improve operational flexibility and reduce the complexity of the displayed content on the switching display device, such as... Figure 1 As shown, the tire defect indication system of this application also includes a foot pedal control component 15 connected to the control device 13.

[0110] The foot pedal control component is used to receive image switching commands. This component can be located at the bottom of the inspection platform, allowing inspectors to input image switching commands while standing by stepping on it. The foot pedal control component is electrically connected to the control device; for example, the connection can be achieved via a copper core wire. The foot pedal control component can be a resettable foot switch with an internal spring reset structure. For example, this spring reset structure can support a 1-2 cm compression amount and a trigger pressure of 5-10 N.

[0111] Accordingly, the control device is also configured to, in response to an image switching command obtained by the foot pedal control component, determine the next defect area following the target defect area as the target defect area to be displayed, according to the sequential order corresponding to at least one defect area in the tire. Based on this, the control device can update the defect information of the target defect area and the partial tire image displayed on the display device after determining the new target defect area.

[0112] In this application, there are various possibilities for the specific method of setting up the indicator light groups on the testing platform, and no limitation is imposed. To ensure stable support for the indicator lights in each indicator light group, such as... Figure 1 As shown, the tire defect indication system also includes a lamp support plate 16 disposed on the inspection table 10. The lamp support plate 16 is parallel to the target plane and is located on the side away from the tire loading end of the inspection table. (As shown in...) Figure 1 In the indicated direction, the side of the inspection platform 10 where the tire support assembly 11 is located is the tire loading platform, while the lamp support plate is located on the side of the inspection platform away from the tire support assembly, so that the lamp support plate is at the rear end of the tire support assembly.

[0113] At least one indicator light group is disposed in the lamp support plate on the side facing the tire. That is, the indicator light group is disposed on the side of the lamp support plate facing the tire support assembly, and when the tire is placed on the tire support assembly, the indicator light group on the lamp support plate faces the tire.

[0114] For ease of understanding, combined with Figure 2 To be explained. Figure 2 As can be seen, the tire support assembly 11 supports the tire in a vertical plane, and the lamp support plate 16 is a vertical panel mounted on the inspection table. Multiple indicator light groups are arranged on the side of the lamp support plate 16 facing the tire support assembly 11. Furthermore, the lamp support plate is located away from the tire loading end of the inspection table; therefore, it does not interfere with the re-inspection personnel placing the tire on the tire support assembly or performing re-inspection. Moreover, after the tire is placed on the tire support assembly, the ring formed by the indicator lights in each indicator light group on the lamp support plate is parallel to the ring containing the tire crown, allowing different indicator lights in the indicator light group to indicate different areas of the tire.

[0115] Based on any of the above tire defect indication systems, this application also provides a tire defect indication method. For example... Figure 5 This illustration shows a flowchart of a tire defect indication method provided in this application. This embodiment can be applied to the control device in the tire defect indication system described in any of the preceding embodiments. The method of this embodiment may include:

[0116] S501, obtain tire defect information.

[0117] The defect information includes: the location information of at least one defective area in the tire.

[0118] The tire defect information can be pre-stored or input into the control device in real time; alternatively, the control device can retrieve it from the tire inspection system's database or cloud platform storage area, with no specific restrictions. For example, the control device obtains tire marking information scanned by the marking scanner, and based on this tire marking information, retrieves the tire defect information corresponding to that tire marking information from within the control device or other storage areas. Other possible methods for obtaining tire defect information can also be implemented; please refer to the previous related introductions for details.

[0119] S502, based on the defect location information of the defect area, control at least one target indicator light in the indicator light group of the tire defect indication system to illuminate, so as to indicate the defect area.

[0120] For example, based on the defect location information of the defect area, at least one target indicator light in the indicator light group that meets the set requirements in terms of distance from the defect area is determined, and the target indicator light is controlled to light up.

[0121] In this embodiment, the control device can control at least one target indicator light in the indicator light group to illuminate based on the defect location information of the defect area in the tire. The illumination of the target indicator light can indicate the defect area of ​​the tire, thereby enabling tire inspection personnel to quickly and accurately locate the defect area in the tire based on the illuminated target indicator light, thus improving the efficiency of tire defect area location.

[0122] Understandably, the diameter of the rings formed by the indicator lights within different indicator light groups varies, and the inner and outer diameters of tires of different sizes will also differ. After the tire is placed on the tire support assembly, some indicator light groups may be obscured by the tire. In such cases, if the indicator lights in the obscured groups are illuminated, it will be difficult for inspectors to see them, thus potentially failing to effectively indicate tire defects.

[0123] Based on this, tire model information can be obtained before the control device illuminates the target indicator light. For example, the tire model information pre-configured by the re-inspection personnel can be obtained. Alternatively, tire model information can be obtained based on tire marking information scanned by a marking scanner; for instance, by obtaining the model information corresponding to the scanned tire marking information according to the stored correspondence between different tire marking information and model information.

[0124] The tire model information is used to characterize the tire's outer or inner diameter.

[0125] Based on this, a target indicator light group can be identified from the at least one indicator light group whose ring diameter matches the outer or inner diameter of the tire, based on the tire model information. Then, based on the defect location information of the defect area, at least one target indicator light in the target indicator light group whose distance from the defect area meets the set requirements is identified, and each target indicator light is controlled to illuminate.

[0126] The process of determining the target indicator light group and identifying the target indicator light that meets the set requirements from the target indicator light group can be found in the relevant descriptions in the previous embodiments, and will not be repeated here.

[0127] In one possible scenario, considering that the tire is a circular ring, in order to more accurately identify the location of defective areas within the tire and facilitate quick location of these areas by inspection personnel, the defect location information in this application may include: the relative deviation angle of the defective area, which is the rotation angle required from the target marking area within the tire to the defective area. For this scenario, the following... Figure 6 Please provide an explanation. For example... Figure 6 This illustration shows another schematic flowchart of the tire defect indication method provided in this application. The method of this embodiment can be applied to the control device mentioned above. The method of this embodiment includes:

[0128] S601, obtain tire defect information.

[0129] The defect information includes: the location information of at least one defective area in the tire.

[0130] In this embodiment, the defect location information of the defect area includes: the relative deviation angle of the defect area, which is the rotation angle required to rotate from the target marking area in the tire to the defect area.

[0131] The target marking area of ​​a tire is a unique and identifiable fixed area on the tire. For example, the target marking area of ​​a tire can be a marking area on the tire that the user uses to print or affix a tire barcode or tire number.

[0132] Since the target marking area of ​​a tire is unique and fixed, by using this target marking area as a reference and determining the relative deviation angle of the defect area in the tire relative to the target marking area, the target indicator light used to indicate the defect area can be accurately and reasonably determined based on the relative positional relationship between each indicator light in the indicator light group and the target marking area.

[0133] Of course, the defect location information of the defect area may also include: the tire part of the tire where the defect area is located.

[0134] S602, obtain tire model information.

[0135] This model information is used to characterize the tire's outer or inner diameter.

[0136] For example, tire model information and defect information can be obtained based on the tire marking information scanned by the marking scanner.

[0137] The specific implementation of obtaining tire defect information and model information can be found in the previous introduction, and will not be repeated here.

[0138] S603, based on tire model information, determine a target indicator group from the at least one indicator group whose ring diameter of the ring formed by each indicator is matched with the outer diameter or inner diameter.

[0139] Understandably, based on the outer or inner diameter dimensions represented by the tire model information, it is possible to select a target indicator light group that is not obscured by the tire and can be used to indicate tire defects.

[0140] For example, the diameter of the ring formed by the indicator lights in the target indicator light group is larger than the outer diameter or smaller than the inner diameter.

[0141] To avoid the indicator lights being too far from the tire and thus failing to effectively indicate defective areas, in this application, the target indicator light group can be an indicator light group where the diameter of the ring formed by the indicator lights is larger than the outer diameter of the tire, and the diameter of the ring formed by the indicator lights is the smallest (or the difference between the diameter of the ring formed by the indicator light group and the outer diameter of the tire is less than a set threshold). Alternatively, the target indicator light group can be an indicator light group where the diameter of the ring formed by the indicator lights is smaller than the inner diameter of the tire, and the diameter of the ring formed by the indicator lights is the largest (or the difference between the diameter of the ring formed by the indicator light group and the inner diameter of the tire is less than a set threshold).

[0142] In practical applications, this application can also determine the target indicator light group by combining the tire part where the defective area is located and the tire model information. For example, if the defective area of ​​the tire is located on the tire crown or sidewall, a target indicator light group is determined from the at least one indicator light group whose ring diameter of each indicator light matches the outer diameter of the tire; if the defective area is located inside the tire, a target indicator light group is determined from the at least one indicator light group whose ring diameter of each indicator light matches the inner diameter of the tire.

[0143] S604, Identify the reference indicator in the target indicator group.

[0144] Among them, the reference indicator light is the indicator light set in the target indicator light group for aligning with the target marking area.

[0145] For example, when a tire is placed on the tire support frame, the target marking area of ​​the tire can be positioned by default in the target direction of the target plane. The target direction can be specified in advance; for example, it can be a direction perpendicular to the surface of the testing platform or a direction perpendicular to one side of the testing platform. Correspondingly, for any indicator light group, the reference indicator light can be the indicator light in the target direction, so that the reference indicator light can be aligned with the target marking area on the tire.

[0146] Taking a vertical plane as an example:

[0147] With the tire support assembly supporting the tire in a vertical plane, the target marking area of ​​the tire can be positioned vertically and directly above the tire. For example... Figure 4 As shown, at this time, tire 20 is in a vertical plane, and target marking area 401 is directly above the tire. Therefore, with the circle containing the tire as the dial face, target marking area 401 is at the 12 o'clock position. Correspondingly, in Figure 4 The topmost indicator in the indicator light group shown is the reference indicator light 122. As can be seen, the reference indicator light 122 is the one directly facing the target marking area in the indicator light group.

[0148] S605, based on the relative deviation angle of the defect area, determine the target indicator in the target indicator group.

[0149] Among them, the difference between the central angle and the relative deviation angle between the target indicator light and the reference indicator light on the ring formed by the indicator lights in the target indicator light group is the smallest.

[0150] It is understandable that the central angle formed by the target indicator light and the reference light is actually the rotation angle required to rotate from the reference indicator light to the target indicator light, which is also the deviation angle of the target indicator light relative to the reference indicator light. Since the reference indicator light is aligned with the target marking area, the deviation angle of the target indicator light relative to the reference indicator light is the smallest compared to the relative deviation angle of the defect area relative to the target marking area. This indicates that the target indicator light is the closest indicator light to the defect area in the target indicator light group, and is naturally the most suitable for indicating the defect area.

[0151] Still combined Figure 4The explanation is as follows: Since the reference indicator light is the topmost indicator light in the target indicator light group, and the target marking area is also located at the top of the tire, when the relative deviation angle between the defect area and the target marking area is determined to be 90 degrees, the target indicator light, rotated 90 degrees relative to the reference indicator light, is closest to the defect area. Assuming the tire forms the dial and the target marking area is at the 12 o'clock position, and the defect area is at the 3 o'clock position, then the indicator light located at the 3 o'clock position in the target indicator light group can also be designated as target indicator light 121.

[0152] Understandably, when there are multiple defective areas in a tire, a target indicator light can be determined for each defective area separately.

[0153] Specifically, when the tire defect indicator has a display device, the control device of this application can also determine the target defect area to be displayed from at least one defect area, and output the defect information of the target defect area and a partial image of the tire to the display device. In this case, the control device determines the target indicator light based on the currently displayed target defect area and the relative deviation angle of the target defect area. The specific process for determining the target indicator light is similar and will not be described in detail here.

[0154] S606, control the target indicator light to illuminate to indicate the defective area.

[0155] In this embodiment, based on the tire model information, a target indicator light group whose ring diameter matches the outer or inner diameter of the ring formed by each indicator light in the at least one indicator light group can be determined. This reduces the possibility of defect areas not being indicated due to the indicator lights in the target indicator light group being blocked by the tire. Furthermore, since the defect location information includes the relative deviation angle of the defect area relative to the target marking area, after determining the reference indicator light in the target indicator light group corresponding to the target marking area of ​​the tire, the target indicator light closest to the defect area can be more accurately determined from the target indicator light group based on the relative deviation angle and the reference indicator light. By illuminating the target indicator light, the inspection personnel can be guided to locate the defect area, improving the efficiency of defect area location.

[0156] Tests revealed that, compared to the 30-60 seconds required to locate defects solely based on database data, the proposed solution combines the target marking area on the tire with the target indicator light, and illuminates the target indicator light to indicate the defect area. The positioning accuracy of locating defects using the indicator light can be within ±5 degrees, and the time required to locate a defect area can be reduced to 5-10 seconds.

[0157] In any of the above embodiments of this application, the defect location information of the defect area of ​​the tire further includes: the tire part where the defect area is located. Based on this, in order to enable the re-inspection personnel to intuitively understand the tire part where the defect area is located, in this application, the control device can also determine the target light color based on the tire part where the defect area is located; and control at least one target indicator light in the indicator light group (such as the target indicator light group) to illuminate and display the target light color.

[0158] The light color varies depending on the tire location. For example, the light color can be preset to green if the defect is on the tread, red if on the sidewall, purple if on the shoulder, and yellow if inside the tire. Similarly, if the defect is on the sidewall, the indicator light can be set to illuminate red after identifying the target indicator for that defect.
