[0021] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0022] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0023] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0024] This invention provides a method for assessing the lifespan of key components of gas appliances. By configuring key nodes in the installation process of hose components and obtaining hose component data for corresponding sampling periods based on these key nodes, the condition of the hose can be assessed to determine whether the hose has undergone a change in condition. Based on the condition change data, a hose simulation model can be constructed. This model can be used for simulation to accurately predict the remaining lifespan of the hose components, thereby enabling precise control over their remaining lifespan and timely replacement within a conservative timeframe to prevent major accidents caused by hose component damage.

[0025] Figure 1 A flowchart illustrating a method for assessing the lifespan of critical components of gas appliances according to an exemplary embodiment of this application is shown. This method is applied to a system for assessing the lifespan of critical components of gas appliances and includes steps S10-S40. The following will be combined with… Figure 1 The technical solution of this application will be described in detail below.

[0026] First, execute step S10 to obtain the hose fitting data of each key node uploaded by the user according to the sampling period.

[0027] The key nodes in this invention can be locations in home kitchens that affect the use of hose fittings, i.e., potential safety hazards. Of course, they can also be scenarios such as commercial kitchens where gas appliances are used.

[0028] When the system's pre-set sampling period arrives, users can collect data on hose fittings corresponding to each key node using mobile devices. Alternatively, staff can periodically visit the site to collect data on hose fittings at key nodes. This data is then uploaded to the gas appliance key component lifespan assessment system, enabling the acquisition of hose fitting data at each key node and facilitating the assessment of hose fitting lifespan.

[0029] Before step S10, that is, before obtaining the hose fitting data of each key node uploaded by the user according to the sampling period, the process may further include:

[0030] The safety hazard points recorded during the installation of hose fittings are considered key points.

[0031] Based on the key nodes and their corresponding layout status information, the importance of each location can be determined.

[0032] Based on the key layouts that affect key nodes in the layout status information, and the importance of each point, the overall importance of the point is obtained;

[0033] The sampling period is determined based on the overall importance of the sampling points.

[0034] Before users upload data on hose fittings at key nodes to the gas appliance key component life assessment system, the system further determines the data collection cycle after hose fitting installation. In other words, after hose fitting installation, workers can identify potential safety hazards around the fittings and input their locations (hazard points) as key nodes into the system. This input also includes the layout status information of these key nodes. The system then determines the importance of each key node based on its layout status and, based on the influence of each key layout and its corresponding importance, first determines the overall importance of each key node. Finally, based on this overall importance, the sampling cycle for the hose fittings is determined. When determining the sampling period for hose fittings based on the overall importance of sampling points, the overall importance of all key nodes can be considered. For example, the overall importance of each key node can be compared to obtain a ranking from smallest to largest. Then, in a relatively conservative manner, the sampling period corresponding to the highest overall importance can be selected as the final sampling period. Furthermore, the overall importance of a sampling point is negatively correlated with its corresponding sampling period; that is, the higher the importance value, the more important the corresponding key node, and the shorter the sampling period required for investigation. Of course, the overall importance of sampling points can also be ranked from largest to smallest.

[0035] This includes determining the importance of a location based on key nodes and their corresponding layout status information, which may further include:

[0036] Based on the key nodes, identify the key layouts in the layout status information that affect the key nodes; the layout status information includes the key layouts that affect the key nodes and other layouts.

[0037] Based on the type of critical layout, obtain the degree of influence of the critical layout on the layout of critical nodes;

[0038] The importance of a location is determined by the type and influence of the critical layout and its impact on the layout of critical nodes.

[0039] The gas appliance critical component life assessment system of this invention determines the importance of each critical node based on its critical nodes and corresponding layout status information. It can then search the layout status information to identify the critical layouts that influence these nodes. Furthermore, based on the type of critical layout, the system determines the layout influence of each critical node. Finally, based on the type influence of the critical layout, the system determines the overall importance of each critical node.

[0040] Specifically, when uploading user hose fitting information, all layout status information and key nodes of the hose fitting can be uploaded. Other key information can also be uploaded. For example, staff will enter various details of the hose fitting during installation as layout status information, including key layouts that affect key nodes. The system can then directly query key layouts that affect key nodes. For example, key layouts could be the layout of the sink, gas stove, water heater, or spatial layout. The sink, gas stove, and water heater layouts, among others, will have varying degrees of impact on the hose fitting during use due to differences in the distance between their installation location and key nodes; this type of impact can be defined as indirect. The impact of spatial layout on hose configuration is relatively fixed. For example, factors such as oil stains and temperature within the space caused by the spatial layout have a generally consistent impact on different locations of the hose fitting (including key nodes); therefore, this type of impact can be defined as direct.

[0041] Based on the type of critical layout, the impact of the critical layout on the layout of critical nodes can be obtained, which may further include:

[0042] Based on the type of critical layout, we can determine how the critical layout affects the critical nodes;

[0043] When the influence method is direct influence, the first layout influence degree of the key layout on the key node is obtained according to the type of key layout;

[0044] When the influence method is indirect, the second influence degree of the key layout on the key node is obtained based on the type of key layout and the degree of weakening of the influence of the key layout to the key node.

[0045] The first layout influence and / or the second layout influence are used as the layout influence.

[0046] The gas appliance critical component life assessment system determines the impact of critical layouts on critical nodes based on their type. The method of influence of a critical layout on a critical node can be determined by its type. For example, when a critical layout is a space containing oil or heat, it can be identified as having a direct impact. Then, based on the type of critical layout (e.g., an oil-contaminated space), the overall oil contamination impact can be calculated based on the space's volume and the oil contamination impact per unit volume, serving as one component of the first-level layout impact. Similarly, a temperature-contaminated space can also be included, and its impact can be calculated using the same method, also serving as one component of the first-level layout impact.

[0047] When critical layouts include the location of a water tank, gas stove, and water heater, their indirect influence can be identified. Then, based on the weakening effect per unit length for each critical layout, the degree of weakening from the critical layout to the critical node is determined. Further, the second degree of influence of the critical layout on the critical node is determined. For example, after determining the distance between the water tank and the critical node, the degree of weakening from the water tank to the critical node can be determined based on the weakening factor per unit length corresponding to the water tank. Then, the second degree of influence of the water tank on the critical node is obtained by subtracting the maximum degree of influence corresponding to the water tank. The first and / or second degree of influence are then integrated to obtain the overall degree of influence of the critical node. For example, if the first and second degree of influence exist independently, only one is considered; if both exist simultaneously, they are superimposed to obtain the overall degree of influence of the critical node.

[0048] Based on the type of critical placement and the degree of weakening of the critical placement's impact on critical nodes, the influence of the critical placement on the second placement of critical nodes can be obtained, which may further include:

[0049] Based on the type of critical placement and the distance between the critical placement and the critical node, obtain the degree of weakening of the impact from the critical placement to the critical node;

[0050] Based on the type and degree of weakening of the critical layout, obtain the degree of influence of the critical layout on the second layout of the critical node.

[0051] When calculating the second-order impact of a critical layout on a critical node using the gas appliance critical component life assessment system, a corresponding mitigation factor can be obtained based on the type of critical layout. Then, based on the mitigation factor and the distance between the critical layout and the critical node, the degree of impact reduction from the critical layout to the critical node can be calculated. Furthermore, based on the type of critical layout, the corresponding maximum layout impact can also be obtained. Finally, by subtracting the maximum layout impact from the impact reduction, the second-order impact of the critical layout on the critical node can be obtained.

[0052] Specifically, the formula for calculating the influence of the second layout is as follows: ,in, This is represented as the second layout influence. Represented as the type of critical layout The corresponding maximum layout impact This is represented as the distance between critical layouts and critical nodes. Represented as the type of critical layout The corresponding weakening factor, This represents the degree of weakening of the impact.

[0053] In step S10, the hose fitting data for each key node uploaded by the user according to the sampling period is obtained, including:

[0054] Obtain images of the tubing appearance at each key node uploaded by the user according to the sampling period;

[0055] Image detection is performed on the appearance image of the hose to obtain abnormal features;

[0056] Based on the abnormal features of the image, obtain the derivative test steps for the requirement test;

[0057] The system sequentially receives hose test data uploaded by users according to the hose testing procedures.

[0058] Anomaly detection is performed on hose test data to obtain derived anomaly characteristics;

[0059] Based on the derived anomaly characteristics, continue executing the derived test steps for obtaining the requirement test to acquire all hose test data;

[0060] Images of the hose's appearance and all hose test data are used as hose fitting data.

[0061] After determining the sampling period, the gas appliance key component life assessment system allows users to upload hose fitting data for each key node at the corresponding sampling period. Specifically, users upload images of the hose's appearance at each key node. The system then performs image detection to identify anomalous features, such as yellowing of the hose surface, cracks, or uneven thickness at the corresponding key node. Based on these anomalous features, further derivative testing steps are determined. For example, if cracks are present on the hose surface, a pressure test may be initiated to further test the hose material's properties. If the pressure test shows abnormal rebound, this is identified as a derivative anomalous feature, prompting further derivative testing steps to obtain all hose test data based on the hose's appearance image. Then, the hose appearance image and all hose test data are used as hose accessory data to evaluate the current state of the hose and determine the state change data to build a hose simulation model.

[0062] Based on the anomaly features of the image, derive the derivative test steps for the requirement test, including:

[0063] Based on the feature type of the image anomaly features, obtain all the steps to be tested corresponding to the feature type, and the required test weights for each step to be tested;

[0064] Based on the feature values ​​of image anomalies and the required test weights for each step to be tested, the required test level for each step to be tested is obtained.

[0065] The degree of requirement testing for each step to be tested is compared, and the step to be tested corresponding to the highest degree of requirement testing is obtained as the derivative test step of requirement testing.

[0066] After obtaining the image anomaly features, when determining the corresponding derivative test steps for demand testing using the gas appliance critical component life assessment system, all test steps corresponding to the feature type of the image anomaly features, and the demand test weight corresponding to each test step, can be obtained. For example, when the feature type of the image anomaly features is "cracks exist on the surface of critical nodes," all test steps corresponding to "cracks exist on the surface of critical nodes" can be found based on this feature type, such as the press-and-rebound test and the airtightness test. Then, based on the crack severity value of the critical node surface and the demand test weights corresponding to test steps such as the press-and-rebound test and the airtightness test, the demand test severity of each test step can be calculated. Then, based on the test steps, the demand test severity of each test step is compared, thereby obtaining the test step corresponding to the highest demand test severity as the derivative test step for demand testing, so as to achieve the most effective testing treatment for critical nodes and improve the efficiency of testing.

[0067] Specifically, the formula for calculating the degree of requirements testing is as follows: ,in, Represented as the first The degree of testing required for each step to be tested. The feature values ​​are represented as image anomaly features. This is represented as the requirement test weight.

[0068] Similarly, when continuing to execute the derivative test steps for obtaining requirement tests based on the derived anomaly features, the corresponding steps when executing the "obtain derivative test steps for requirement tests based on image anomaly features" step can also be adopted to obtain all the tubing test data corresponding to the image anomaly features and derived anomaly features.

[0069] Next, proceed to step S20: assess the current state of the hose based on the hose fitting data and obtain state change data.

[0070] Hose fitting data can include hose appearance images and hose test data. When evaluating the current condition of the hose based on this data, both the appearance images and test data can be evaluated separately. The results of both evaluations are then combined to determine the condition change data. This condition change data can then be used to accurately construct a hose simulation model.

[0071] In step S20, the current state of the hose is evaluated based on the hose fitting data, and state change data is obtained, including:

[0072] Compare the appearance image of the hose with the initial appearance image of the hose to obtain the first type of state change data;

[0073] Compare the hose test data with the initial hose test data to obtain the test difference data;

[0074] Based on the test difference data and the corresponding derivative test steps, obtain the second type of state change data;

[0075] The first type of state change data and the second type of state change data are used as state change data.

[0076] When evaluating the current condition of a hose based on its appearance image, the current appearance image can be compared with the initial appearance image to obtain first-type state change data. For example, comparing the current hose surface with the initial hose surface at installation reveals the surface differences. If cracks are present on the current hose surface, the degree of cracking can be used as first-type state change data based on these differences. During the derived testing steps, the hose is pressed to observe its rebound. This rebound data is then compared with the initial rebound data at installation to obtain the test rebound difference data. Further, based on the first-type and second-type state change data (i.e., other derived second-type state change data), the state change data for each critical node can be determined. For example, after obtaining the test rebound difference, further derived testing steps can be used to determine changes in the material of the hose fittings. For instance, a slower rebound of the hose fittings indicates a degree of hardening at the corresponding critical node. Then, a hose simulation model can be constructed based on this degree of hardening and other types of second-order state change data, combined with the hose's basic data.

[0077] Specifically, the difference between the hose test data and the initial hose test data is calculated to obtain the test difference data. The formula is as follows: ,in, This is represented as test difference data. This represents the initial test data for the hose. This is represented as hose test data.

[0078] Next, step S30 is executed to obtain a hose simulation model containing each key node based on the state change data and hose basic data.

[0079] After obtaining state change data, such as localized hardening of the hose, the corresponding state change data and basic hose data can be used to obtain a hose simulation model containing each key node. The basic hose data is constructed based on the materials used in the production of hose fittings, combined with the length and shape of the hose after installation.

[0080] Next, step S40 is executed to perform simulation using a hose simulation model to predict the remaining lifespan of the hose fittings.

[0081] When simulating using a hose simulation model, the remaining lifespan of hose fittings can be predicted based on the current state change data and the corresponding acquisition cycle time.

[0082] Specifically, simulations are performed using a hose simulation model to predict the remaining lifespan of hose fittings, including:

[0083] Simulation was performed using a hose simulation model to obtain predicted data for hose fittings at key nodes in the next sampling period.

[0084] Determine if the predicted data for the hose fittings is greater than the set value:

[0085] If so, continue uploading the hose fitting data for each key node according to the sampling cycle, and update the hose simulation model again;

[0086] If not, the sampling period is adjusted based on the predicted data and set values ​​of the hose fittings. The data of the hose fittings at each key node is uploaded according to the adjusted sampling period, and the hose simulation model is updated again. When the adjusted sampling period is less than the set period, the time of the adjusted sampling period corresponding to the time of the less than the set period is taken as the remaining life of the hose fittings.

[0087] When predicting the remaining lifespan of hose fittings, a hose simulation model based on state change data can be used to simulate the next sampling period, thereby obtaining predicted hose fitting data for key nodes in the next sampling period. Then, it is determined whether the predicted hose fitting data is greater than a set value. If the predicted hose fitting data is greater than the set value, it indicates that the current sampling period can continue, and the upload of hose fitting data for each key node can continue, with the hose simulation model updated again. At this point, it is not necessary to assess the remaining lifespan of the hose fittings. If the predicted hose fitting data is less than or equal to the set value, it indicates that the current sampling period is not conservative enough and needs to be shortened. This is achieved by calculating the difference between the predicted hose fitting data and the set value. This predicted hose fitting data corresponds to the state change data; that is, the predicted hose fitting data is obtained by simulating the predicted state change data according to the sampling period. Of course, if there is no state change data, the prediction can also be based on the natural aging period. Based on the difference data, the corresponding cycle adjustment amount for the predicted data of the hose fittings can be obtained by looking up a table. If multiple predicted data for hose fittings exist, the largest cycle adjustment amount is selected as the adjustment amount for adjusting the sampling cycle. After adjusting the sampling cycle using the cycle adjustment amount, the hose fitting data for each key node is uploaded using the adjusted sampling cycle, and the hose simulation model is updated again to ensure the prediction accuracy of the hose simulation model at all times. Then, if, within a certain adjusted sampling cycle, the predicted next adjusted sampling cycle is shorter than the set cycle, it indicates that the hose fitting can no longer be used in the next adjusted sampling cycle. Therefore, the hose fitting needs to be replaced in a timely manner to ensure that no safety hazards occur.

[0096] In summary, the present invention discloses a method and system for assessing the lifespan of key components of gas appliances. By configuring key nodes during the installation process of hose fittings, it can conservatively determine the sampling period after hose installation based on the set key nodes. The hose fitting data obtained during this sampling period is then used to assess the hose condition, accurately determining the hose simulation model corresponding to the current hose condition. This model can then be used for simulation to accurately predict the remaining lifespan of the hose fittings. This allows for precise control over the remaining lifespan of the hose fittings and timely replacement within a conservative timeframe to prevent major accidents caused by hose fitting damage. Therefore, the present invention effectively overcomes the various shortcomings of existing technologies and has high industrial application value.
