[0026] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] In order to solve the problem of safety hazards posed by jewelry risks, deep learning assessment models can be used to detect jewelry risks. However, the training process of deep learning assessment models is complicated, the threshold is high, the cost is high, the calculation is complex, and the detection results are not intuitive, which cannot attract enough attention from users.

[0028] In this regard, the present application provides a method for risk assessment of jewelry, which is not only simple and fast to implement, but also can improve the problem of non-intuitive results of jewelry risk assessment in the prior art. Specifically, the method for risk assessment of jewelry provided by the present application includes: after detecting the jewelry at a preset position, obtaining the sensor data at the preset position; evaluating the sensor data to obtain the risk level of the jewelry; sending the preset position and risk level to a display device, so that the display device displays a warning sign corresponding to the risk level at the preset position to prompt the user to eliminate the risk.

[0029] It should be noted that the jewelry risk assessment device proposed in the present application is an electronic control unit (ECU) or a terminal device, etc., and the present application does not impose any restrictions on this. In addition, the jewelry risk assessment device can exchange data with other devices, such as receiving sensor data of a preset position sent by any sensor in the sensor module, sending the preset position and risk level of the jewelry to the display device, receiving the image obtained by the camera device at the preset position, and executing the jewelry risk assessment method proposed in the present application.

[0030] It should also be noted that the present application adopts a buried point method to set up multiple preset positions on the vehicle, such as the center console, the co-pilot platform, the main driver's platform, the steering wheel, the interior rearview mirror, the exterior rearview mirror and the roof, etc., and also uses at least one sensor in the sensor module to collect sensor data at the preset position. The sensor data may include, for example, area sensor data, mass sensor data and sharpness sensor data. The present application does not limit the sensor for collecting sensor data. For example, the sensor module may include an ultrasonic sensor, a weight sensor, an ultrasonic area meter, etc., wherein the weight sensor can detect the weight of the ornament, the ultrasonic sensor can detect the sharpness of the ornament, and the ultrasonic area meter can detect the area of ​​the ornament.

[0031] It should also be noted that since the jewelry risk assessment device collects sensor data by means of buried points, and the sensor data directly reflects the physical properties of the jewelry, it can accurately and quickly collect sensor data and assess the risk level of the jewelry. After assessing the risk level, the jewelry risk assessment device sends the preset position and risk level of the jewelry to the display device to prompt the user to eliminate the risk, so that the user can have an intuitive feeling of the jewelry risk, thereby attracting enough attention and choosing to actively remove the jewelry, or replace the jewelry with safer materials and shapes, so as to reduce the damage caused by the jewelry to the driver and passengers in traffic safety accidents, thereby improving user experience and driving safety.

[0032] In order to better understand the jewelry risk assessment method of this application, Figure 1As shown, the present application provides an embodiment of a jewelry risk assessment method. Next, the present application will use a jewelry risk assessment device as an execution subject to Figure 1 The described jewelry risk assessment method is explained, specifically:

[0033] 101: After detecting the ornament at the preset position, obtain the sensing data at the preset position.

[0034] In order to evaluate the jewelry, the jewelry risk assessment device, after detecting the jewelry at the preset position, obtains the sensing data at the preset position from a large amount of received sensing data.

[0035] It should be noted that the prior art uses a complex deep neural network image detection method when detecting accessories, so there are still problems of complex calculations and low efficiency when detecting accessories. In order to improve the detection efficiency of accessories and simplify the algorithm, the present application also provides an implementable method. Before detecting accessories at a preset position, the accessory risk assessment device receives the sensor data sent by multiple sensors of the sensor module in real time, and monitors whether the sensor data has a jump to preliminarily determine the preset position where the accessories may be set. Although the implementation of the aforementioned monitoring method is very simple, there is still a problem of low accuracy. Therefore, after determining the preset position, the present embodiment further verifies using a camera device to determine whether the accessories are actually set at the preset position. The camera device can be installed above the cockpit and on the skylight, etc. Specifically, before detecting the accessories at the preset position, the method also includes: receiving sensor data sent by multiple sensors and monitoring the jump of the sensor data; if the sensor data of the jump is monitored, determining the target sensor that sends the jump data and the preset position corresponding to the target sensor, and using the camera device to shoot the preset position; recognizing the captured image to verify whether the accessories are set at the preset position, and if the verification passes, determining that the accessories at the preset position are detected.

[0036] It should also be noted that, in order to improve the accuracy of image processing and reduce the amount of calculation, when the jewelry risk assessment device uses the camera device to shoot the preset position, it can start the camera device again when the sensor data that jumps is detected, and adjust the shooting angle of the camera device according to the shooting angle parameter corresponding to the preset position, so that the preset position is in the center of the shooting screen of the camera device, so as to improve the accuracy of positioning, reduce the amount of calculation of image processing, and save power. In addition, in order to further improve the accuracy of image processing and reduce the amount of calculation, the jewelry risk assessment device can also fix the shooting angle of the camera device, and continue to shoot the car environment, obtain the first timestamp of the first sensor data before the sensor data jumps, and the second timestamp of the second sensor data after the sensor data jumps, and then obtain the first image taken at the first timestamp and the second image taken at the second timestamp. The first image and the second image are the images before and after the sensor data jumps. By comparing the first image and the second image, the redundant background can be removed and the changed part can be quickly obtained, that is, the jewelry set at the preset position.

[0037] 102: Evaluate the sensor data to obtain the risk level of the jewelry.

[0038] Among them, when evaluating the sensor data, the jewelry risk assessment device can adopt a threshold comparison method, that is, first determine the threshold interval to which the sensor data belongs, and then determine the risk level of the jewelry according to the risk level corresponding to the threshold interval.

[0039] It should be noted that, during the evaluation, the sensor data can be evaluated based on at least one evaluation indicator, and the evaluation indicator includes at least one of an area indicator, a quality indicator, and a sharpness indicator. Accordingly, the sensor data includes area sensor data, quality sensor data, and sharpness sensor data. For example, based on the area indicator, the quality indicator, and the sharpness indicator, the area sensor data, the quality sensor data, and the sharpness sensor data are evaluated respectively.

[0040] It should also be noted that, during the evaluation, the aforementioned multiple indicators can be used simultaneously to evaluate the sensor data to obtain multiple risk levels, and the highest risk level among the multiple risk levels can be sent to the display device, so that the display device displays the highest risk level at a preset position, and when the risk assessment device receives the user's selection instruction, it pushes the aforementioned multiple risk levels and the corresponding indicators to the display device, so that the user can view the specific risk situation and have a more intuitive understanding of the risk of the jewelry.

[0041] 103: Sending the preset position and the risk level to the display device, so that the display device displays a warning mark corresponding to the risk level at the preset position to prompt the user to eliminate the risk.

[0042] The display device displays a picture of the automobile environment, and displays a warning sign corresponding to the risk level of the accessories at a preset position in the picture. Since the risk level sign is displayed at the preset position, the user can quickly know the risk level of the accessories at the preset position through the sign, and then take corresponding measures, such as removing the accessories or replacing them with safe accessories, to eliminate the risk.

[0043] It should be noted that there can be several preset positions, such as the center console, the co-pilot platform, the main driver's platform, the steering wheel, the interior rearview mirror, the exterior rearview mirror and the roof. Although the present application improves the problem of non-intuitive results of risk assessment of accessories in the prior art by displaying the risk level of accessories at preset positions, there is still room for improvement in terms of intuitiveness. Because, on the one hand, the image of the car environment as a background is very messy, with too much invalid information and visual interference. On the other hand, as the number of preset positions increases, if accessories are set at multiple preset positions and there are risks in the accessories, the displayed picture will be more messy, making the risk level of the accessories not very intuitive.

[0044] Furthermore, in order to reduce visual interference and improve the intuitiveness of risk assessment, the jewelry risk assessment device can model and render the automobile environment before displaying the preset position of the jewelry and the risk level logo, obtain a background image simulating the automobile environment, and then display the preset position and risk level logo on the simulated background image.

[0045] Furthermore, based on the examples of the aforementioned preset positions, it can be seen that some of the preset positions are inside the vehicle, and other preset positions are outside the vehicle. In order to further enhance the intuitiveness, the jewelry risk assessment device can also display the preset positions and risk levels of the jewelry through the perspective inside the vehicle and the perspective outside the vehicle respectively. Different risk levels are marked with different colors or shapes, for example, red for high risk, orange for medium risk, and yellow for low risk. Depending on the perspective, the displayed image can include the perspective inside the vehicle and the perspective outside the vehicle. For example, the perspective inside the vehicle Figure 1 As shown, the preset positions in the car include the center console, the co-pilot platform, the main driver's platform, the steering wheel and the interior rearview mirror, etc. The outside view angles are as follows: Figure 2 As shown, the preset positions outside the car include the exterior rearview mirror and the roof, etc. The risk level can be represented by a triangle symbol or any other shape as shown in the figure. Different risk levels can be represented by different shapes or colors, so that the user can intuitively know the risk level of the accessories. Figure 2 and Figure 3In the diagram, a triangle filled with a slash pattern indicates a high risk (such as the triangles on the steering wheel, the co-pilot console, and the exterior mirrors), a triangle filled with a vertical line pattern indicates a medium risk (such as the triangle on the driver's console), and a triangle filled with a dot pattern indicates a low risk (such as the triangle on the center console). Figure 2 as well as Figure 3 The symbols in are examples of the present application and should not limit the technical solutions of the present application.

[0046] It should be noted that two perspectives can be displayed simultaneously, each occupying half of the screen of the display device, and can also display a perspective with a higher priority. When the user clicks the switch button on the screen, it switches to the other perspective. In order to determine the perspective with a higher priority, the highest risk levels of the two perspectives can be compared, and the perspective with a higher risk level can be used as the perspective with a higher priority; further, if the highest risk levels are the same, the number of the highest risk levels is compared, and the perspective with a larger number is used as the perspective with a higher priority; further, if the number of the highest risk levels is the same, the number of all risk levels is compared, and the perspective with a larger number is used as the perspective with a higher priority; further, if the number of all risk levels is also the same, a perspective is randomly determined as the perspective with a higher priority.

[0047] In another possible implementation, in order to improve the warning effect, the jewelry risk assessment device also provides a safety promotional video for each preset position, and when the user clicks the warning mark on the screen of the display device, the safety promotional video corresponding to the mark is played. Specifically, after the step of sending the preset position and risk level to the display device, the method also includes: receiving a user's selection instruction for the warning mark; determining the warning mark selected by the user, and obtaining the safety promotional video corresponding to the warning mark; pushing the safety promotional video to the display device, so that the display device plays the safety promotional video.

[0048] Among them, the aforementioned warning logo is not only used to indicate the risk level of the jewelry, but also used to receive the user's selection instructions. When selected by the user, it triggers the playing of the safety promotional video corresponding to the warning logo. The safety promotional video is associated with the preset position and safety level. Different preset positions and / or different safety levels correspond to different safety promotional videos.

[0049] In summary, the embodiments of the present application quickly assess the risk level of accessories based on the sensor data of the accessories, and prompt the user with the risk level, thereby improving the problem of non-intuitive results of risk assessment of accessories in the prior art, allowing users to have an intuitive feeling of the risk level of the accessories, thereby attracting sufficient attention from users and improving user experience and driving safety.

[0050] In addition, although the jewelry risk level assessment method provided in the aforementioned embodiment can improve the problem of non-intuitive jewelry risk assessment results existing in the prior art, the accuracy of the assessment still needs to be improved, because in actual applications, the risk level of the jewelry is associated with the preset position of the jewelry. If the same assessment index is used to evaluate the sensor data, the evaluation result may be inaccurate. For example, when evaluating the accessories on the steering wheel and the center console, they are evaluated based on the sharpness index, which may lead to inaccurate evaluation results at the center console. Because the steering wheel is facing the driver, the airbag often pops out from the steering wheel, causing the accessories on the steering wheel to become a weapon of injury when they pop out, and the accessories installed on the steering wheel are often lightweight items, so the sharpness index can be used as the main evaluation index. The center console is not facing people and usually has no emergency devices. The decorations on the center console usually cause the problem of blocked vision. Therefore, compared with the quality index and sharpness index, the area index is the main evaluation index. If the sharpness index is used as the main evaluation index to evaluate the decorations on the center console, it may lead to inaccurate risk assessment of the decorations on the center console.

[0051] It can be seen that due to the location characteristics of the preset position and the characteristics of the accessories usually placed at this position, the risks that need to be focused on may be different when the accessories are in different positions. Therefore, corresponding evaluation indicators need to be adopted according to the position of the accessories.

[0052] Based on this, the present application also proposes another embodiment of the jewelry risk assessment method. In order to improve the accuracy of the assessment, the jewelry risk assessment device first obtains the corresponding assessment index according to the location of the jewelry, and then evaluates the sensor data based on the assessment index, so that the assessment result is more accurate. Figure 4 , the jewelry risk assessment method provided in the embodiment of the present application is described in detail, specifically:

[0053] 401: After detecting the ornament at the preset position, obtain the sensing data at the preset position.

[0054] 402: Obtain the evaluation index corresponding to the accessory according to the preset position.

[0055] Among them, considering that the risks of accessories in different positions may be different, in order to achieve an accurate assessment of the risk level of accessories, the accessory risk assessment device can also obtain the corresponding evaluation index according to the location of the accessories, and use the evaluation index as the evaluation index corresponding to the accessories. The evaluation index can be, for example, an area index, a quality index, or a sharpness index. Furthermore, the present application also provides a specific implementation method. Specifically, the preset position includes at least one of the center console, the co-driver's platform, the main driver's platform, the steering wheel, the interior rearview mirror, the exterior rearview mirror, and the roof. According to the preset position, the step of obtaining the evaluation index corresponding to the accessories includes: if the preset position is the center console, the main driver's platform, or the co-driver's platform, then obtain the area index; if the preset position is the steering wheel or the interior rearview mirror, then obtain the sharpness index; if the preset position is the exterior rearview mirror or the roof, then obtain the quality index.

[0056] It should be noted that when the accessories are set on the center console, main driver's platform or co-driver's platform, the main problem is the obstruction problem. If the driver's line of sight is blocked, he cannot observe the road conditions, which may lead to traffic accidents. Therefore, when the preset position is the center console, main driver's platform or co-driver's platform, the area index is obtained; when the accessories are set on the steering wheel or the rearview mirror inside the car, the main problem is the injury problem. If the airbag is deployed or the brakes are suddenly applied, it is very likely that the accessories will become a weapon of injury and cause harm to the driver and passengers. Therefore, when the preset position is the steering wheel or the rearview mirror inside the car, the sharpness index is obtained; when the accessories are set on the outside rearview mirror or the roof, the main problem is the falling off problem. If the accessories fall off, they may hit the rear car glass and cause great life and property safety to the rear car. Therefore, when the preset position is the outside rearview mirror or the roof, the quality index is obtained.

[0057] 403: Evaluate the sensor data based on the evaluation index to obtain the risk level of the jewelry.

[0058] Among them, the jewelry risk assessment device evaluates the sensor data based on the assessment index to obtain the risk level of the jewelry. For example, when the assessment index is the area index, the area sensor data is evaluated; when the assessment index is the quality index, the quality sensor data is evaluated; when the assessment index is the sharpness index, the sharpness sensor data is evaluated.

[0059] It should be noted that when the present application evaluates based on the evaluation indicators corresponding to the preset positions, it can specifically adopt a threshold comparison method, for example, obtaining multiple threshold intervals corresponding to the evaluation indicators, and then comparing the sensor data with the multiple threshold intervals respectively to determine the threshold interval to which the sensor data belongs, and finally obtaining the risk level corresponding to the threshold interval as the risk level of the jewelry. The aforementioned threshold comparison process is simple and has a small amount of calculation. By implementing this method, the risk level of the jewelry can be quickly determined, but the accuracy of this method can be improved. In this regard, the present application also provides another feasible implementation method. In this implementation method, according to the severity of the safety accidents that may be caused by the jewelry at different preset positions, the threshold intervals of the evaluation indicators at different preset positions are adaptively adjusted, so that the evaluation indicators at different preset positions correspond to different threshold intervals, so as to improve the alarm sensitivity of important positions, thereby improving the accuracy of risk assessment. Specifically, the aforementioned step of evaluating the sensor data based on the evaluation index to obtain the risk level of the jewelry includes: obtaining multiple threshold intervals corresponding to the evaluation index at a preset position; comparing the sensor data with each threshold interval to obtain the threshold interval to which the sensor data belongs; and using the risk level corresponding to the threshold interval to which the sensor data belongs as the risk level of the jewelry.

[0060] Among them, the jewelry risk assessment device can quickly determine the risk level of the jewelry by using the threshold comparison method. At the same time, it also uses the multiple threshold intervals corresponding to the evaluation indicators at the preset position for evaluation. Because the threshold intervals corresponding to the evaluation indicators are different according to the preset positions of the jewelry, the present application provides three specific implementation methods. It is assumed that each evaluation standard corresponds to three threshold intervals, including a first threshold interval, a second threshold interval and a third threshold interval, and the first threshold interval, the second threshold interval and the third threshold interval correspond to high risk, medium risk and low risk, respectively. Specifically:

[0061] In a specific implementation, if the accessories are placed on the co-pilot platform and the main driver's platform, not only will they block the road ahead to a certain extent, but the reflection of the accessories on the front windshield will also interfere with the driver's line of sight, causing the driver to make a wrong judgment on the road ahead, thereby affecting the user experience and driving safety. The accessories on the center console block the driver's line of sight a little better, so the warning sensitivity of the co-pilot platform and the main driver's platform is set higher than that of the center console. Furthermore, since the co-pilot platform not only interferes with the driver's line of sight ahead, but also blocks the line of sight of the exterior rearview mirror, the warning sensitivity of the co-pilot platform is higher than that of the main driver's platform. In general, the threshold intervals of the area indexes of the co-pilot platform, the main driving platform and the center console are set to increase in sequence, so that the alarm sensitivity of the co-pilot platform, the main driving platform and the center console decreases in sequence. For example, when the preset position is the co-pilot platform, the threshold intervals of the area index are the first threshold interval (60, +∞), the second threshold interval (20, 60], and the second threshold interval (0, 20]; when the preset position is the main driving platform, the threshold intervals of the area index are the first threshold interval (80, +∞), the second threshold interval (40, 80], and the second threshold interval (0, 40]; when the preset position is the center console, the threshold intervals of the area index are the first threshold interval (100, +∞), the second threshold interval (60, 100], and the second threshold interval (0, 60], wherein the unit of each value in the threshold interval corresponding to the area index is cm 2 (square centimeters).

[0062] In another specific implementation, when a car brakes suddenly or hits an obstacle, the decorations on the steering wheel and the interior rearview mirror may cause harm to the driver and passengers, but the damage caused by the decorations on the steering wheel will obviously be more serious, because the steering wheel is facing the driver's chest and face, and there is an airbag underneath. Therefore, when an accident occurs, the decorations on the steering wheel will cause more serious damage than the decorations on the interior rearview mirror. Therefore, the warning sensitivity of the steering wheel is set higher than that of the interior rearview mirror, so that the warning sensitivity of the steering wheel is greater than that of the interior rearview mirror. In general, the threshold intervals of the sharpness index of the steering wheel and the interior rearview mirror are set to decrease in sequence, so that the warning sensitivity of the steering wheel and the interior rearview mirror decreases in sequence. For example, when the preset position is the steering wheel, the threshold intervals of the sharpness index are respectively the first threshold interval (0, 80], the second threshold interval (80, 120], and the second threshold interval (120, 180); when the preset position is the interior rearview mirror, the threshold intervals of the sharpness index are respectively the first threshold interval (0, 60], the second threshold interval (60, 100], and the second threshold interval (100, 180), wherein the unit of each value in the threshold interval corresponding to the sharpness index is degree.

[0063] In another specific implementation, since the load-bearing capacity of the exterior rearview mirror is not as good as that of the roof, and the sturdiness of the accessories installed on the exterior rearview mirror is not as good as that on the roof, if the accessories are too heavy, they are not only more likely to fall, but also easily cause damage to the exterior rearview mirror. Therefore, compared with the roof, the alarm sensitivity of the exterior rearview mirror is set higher, so that the alarm sensitivity of the exterior rearview mirror is greater than the alarm sensitivity of the roof. In general, the threshold intervals of the quality indicators of the exterior rearview mirror and the roof are set to increase in sequence, so that the warning sensitivity of the exterior rearview mirror and the roof decreases in sequence. For example, when the preset position is the exterior rearview mirror, the threshold intervals of the quality indicator are respectively the first threshold interval (100, +∞), the second threshold interval (50, 100], and the second threshold interval (0, 50]; when the preset position is the roof, the threshold intervals of the quality indicator are respectively the first threshold interval (200, +∞), the second threshold interval (100, 200], and the second threshold interval (0, 100], wherein the unit of each value in the threshold interval corresponding to the quality indicator is g (gram).

[0064] 404: Sending the preset position and risk level to the display device, so that the display device displays a warning mark corresponding to the risk level at the preset position to prompt the user to eliminate the risk.

[0065] Among them, the jewelry risk assessment device can not only push the risk level to the display device, but also push the assessment indicators corresponding to the risk level, so that the user can intuitively know the specific reasons why the jewelry is risky. In addition, more targeted improvement measures can be pushed according to the assessment indicators and threshold intervals. For example, when the assessment indicator of the preset position is the area indicator, the user is prompted to replace the jewelry with a small size; when the assessment indicator of the preset position is the quality indicator, the user is prompted to replace the jewelry with a soft material; when the assessment indicator of the preset position is the sharpness indicator, the user is prompted to replace the jewelry with rounded corners. This application does not limit the number of risk levels. For example, the risk levels include high risk, medium risk, and low risk.

[0066] In summary, the embodiments of the present application take into account the correlation between the risk level of accessories and the location of accessories, and evaluate the risk level of accessories according to the evaluation index corresponding to the location of accessories, thereby improving the accuracy of accessory risk assessment.

[0067] The present application also provides an embodiment of a jewelry risk assessment system, such as Figure 5As shown, the jewelry risk assessment system includes a jewelry risk assessment device 510, a sensor module 520 and a display device 510, wherein the sensor module 520 includes at least one sensor, wherein: the jewelry risk assessment device 510 is connected to the sensor module 520 and the display device 530 respectively, and the jewelry risk assessment device 510 is used for the jewelry risk assessment method in the aforementioned embodiment; the sensor module 520 is set within the detectable range of the sensor data and is used to detect the sensor data; the display device 530 is used to display the warning mark corresponding to the risk level at a preset position. Next, in order to better understand the jewelry risk assessment system provided by this application, this application will provide a more detailed description of the jewelry risk assessment system, specifically:

[0068] The aforementioned sensor module 520 includes at least one sensor, such as an ultrasonic sensor, a weight sensor, an ultrasonic area meter, etc., and there may be multiple sensors of the same type, which are respectively set at different positions of the car to detect the sensor data of the accessories at different positions. The ultrasonic sensor is used to detect the sharpness of the accessories, the ultrasonic area meter is used to detect the vertical section area of ​​the accessories, and the weight sensor is used to detect the weight of the accessories. In another embodiment, the accessory risk assessment system also includes a camera device, which is used to take pictures of the car environment to obtain images including the preset position and the accessories.

[0069] It should be noted that, in order to collect the sensor data of the preset position, at least one sensor in the sensor module 520 is set at a position where the sensor data of the preset position can be collected. Although different sensors have different setting positions according to different data collection principles, each sensor is set within the detectable range of the sensor data. Specifically, the weight sensor is set on the medium where the ornament is located, or on an object connected to the medium where the ornament is located. For example, the weight sensor can be installed under the outer shell of the center console, the co-pilot platform, the main driving platform, the steering wheel, the interior rearview mirror, the exterior rearview mirror and the roof, and the weight of the ornament above the outer shell can be detected; the ultrasonic sensor and the acoustic wave area meter are set in front of the ornament, for example, for the roof from the perspective of the outside car, the ultrasonic sensor and the acoustic wave area meter can be set at the sunroof, for the exterior rearview mirror from the perspective of the outside car, the ultrasonic sensor and the acoustic wave area meter can be set near the front windshield and the pillar, and for the preset position from the perspective of the inside car, the ultrasonic sensor and the acoustic wave area meter can be set above the cockpit, and each preset position from the perspective of the inside car can be detected.

[0070] It should also be noted that since the weight sensor needs to detect the weight of the ornament by contacting the medium, when the weight sensor is set on the medium where the ornament is located, for example, when the weight sensor is installed under the co-pilot platform, the main driving platform, or the steering wheel, the gravity sensor may be installed in the center range of the airbag. Therefore, when danger occurs, the sensor will also be ejected under the impact of the airbag, thus becoming a weapon that hurts people. In this regard, the weight sensor can be connected by welding to the non-center range of the airbag ejection, while ensuring that the sensor is still within the detectable range of the sensor data.

[0071] The jewelry risk assessment device 510 is used to execute the aforementioned jewelry risk assessment method, and is connected to the sensor module and the display device, for example, via a controller area network (CAN) bus. After receiving the data sent by the sensor module, the jewelry risk assessment device evaluates the sensor data to obtain the risk level of the jewelry, and sends the preset position and risk level to the display device, so that the display device displays the preset position and risk level to prompt the user to remove the risk.

[0072] The display interface of the display device 530 includes a warning mark for indicating the preset location of the jewelry, and the warning mark indicates different risk levels according to different colors or shapes. For example, a red risk warning mark indicates high risk, an orange risk warning mark indicates medium risk, and a yellow risk warning mark indicates low risk.

[0073] It should also be noted that the warning sign can also be used to receive user selection instructions. When the user clicks on the risk warning sign, the risk warning sign is selected, triggering the center console screen to jump to display the safety promotional video corresponding to the warning sign, that is, the safety accidents that may occur when the accessories are placed at the location of the risk warning sign.
