[0019] Embodiment 1
[0020] like Figure 1 As shown, the present application provides a method for detecting dustproof performance of an explosion-proof junction box, the method comprising:
[0021] Step S100: Acquire structural information and material information of the explosion-proof junction box;
[0022] In the embodiment of the present application, a connection is first established with a database storing information related to the explosion-proof junction box, and the structural information and material information of the explosion-proof junction box are retrieved from the database according to the required model, specification or other identification information of the explosion-proof junction box.
[0023] Structural information includes the overall structure, component layout, and connection method of the explosion-proof junction box. The overall structure describes the appearance, size, and explosion-proof design features of the junction box, such as the shape of the explosion-proof shell, the opening method, etc. The component layout includes the various components inside the junction box, such as terminals, fuses, switches, etc., and describes their positions and arrangements in the junction box. The connection method describes the connection method between the various components and between the junction box and external equipment, including cable entry, fixing method, etc. Material information includes the materials used for the shell, internal components, and seals of the explosion-proof junction box. Specifically, it includes the shell material, internal component material, and seal material.
[0024] Step S200: establishing a simulation space with the structural information and the material information, fitting the pressure detection device to the simulation space, performing a sealing simulation test on the structural information and the material information, and determining a dustproof performance detection target;
[0025] In the embodiment of the present application, a high-precision 3D model is established in the simulation software based on the overall structure, component layout and other detailed structural information of the explosion-proof junction box, ensuring that each component in the model, such as the terminal block, switch, etc., is accurately placed according to the actual position and size.
[0026] Based on the material information, each part of the 3D model is given real physical properties, such as elastic modulus, Poisson's ratio, density, explosion-proof, corrosion-resistant and other properties. These properties affect the mechanical behavior and dust-proof performance during the simulation process.
[0027] Add a virtual pressure detection device model to the simulation space, which can simulate the functions and performance of the real device. According to actual needs, set the parameters such as pressure detection range, accuracy and frequency. Configure the simulation software to record and analyze pressure data in real time.
[0028] In the simulation environment, different pressure conditions are applied to the junction box to simulate the conditions that may be encountered in actual use. Pressure conditions include normal working pressure, overload pressure, etc.
[0029] Use simulation software to monitor pressure changes in various parts of the junction box. Record any possible leaks, deformations or damage. Perform a detailed analysis of the data collected during the simulation to identify weaknesses in the dustproof performance of the junction box.
[0030] According to the simulation results, set specific dustproof performance testing goals, such as ensuring no leakage under a certain pressure.
[0031] Step S300: configuring control parameters of the pressure detection device, wherein the control parameters include output pressure, wherein the control parameters are control data generated by analyzing and processing the structure information and material information through a pressure analysis module;
[0032] In the embodiment of the present application, the structural information and material information of the explosion-proof junction box are first input into the pressure analysis module. Such information includes but is not limited to the size, shape, sealing design, material type and strength of the outer shell and internal parts of the junction box. At the same time, a series of analysis parameters are set, such as the expected pressure range, the rate of pressure change, the test duration, etc.
[0033] Based on the input structural information and material information, the pressure analysis module builds a high-precision 3D simulation model to simulate a real explosion-proof junction box. The pressure analysis module applies a preset pressure range on the simulation model and simulates the change in pressure. In this process, the module considers factors such as the elasticity, plasticity, and possible deformation of the material. While applying pressure, the pressure analysis module detects the sealing performance and dustproof ability of the junction box in real time. For example, check whether there are leaks, record the deformation of each part, and evaluate the dustproof effect.
[0034] After the simulation is completed, the pressure analysis module will analyze the collected data, including the maximum pressure, the specific location of the leak point, the degree of deformation, etc. For example, when analyzing the maximum pressure, the pressure analysis module records the maximum pressure value that the junction box can withstand during the simulation. By comparing the preset pressure range and the actual maximum pressure, it is evaluated whether the pressure bearing capacity of the junction box meets the design requirements. Through analysis, the pressure analysis module generates a detailed report showing the performance of the junction box under different pressure conditions. This report will serve as the basis for configuring pressure testing equipment and formulating test plans.
[0035] Finally, based on the results of simulation and analysis, the pressure analysis module outputs control data, including the pressure value to be applied at different test stages, the rate of pressure change, and the duration, etc. These data will be directly used to configure the control parameters of the pressure detection equipment.
[0036] Step S400: Based on the control parameter and the dustproof performance detection target, exchanging pressure sensor data;
[0037] In the embodiment of the present application, a pressure sensor is used to monitor the pressure in the junction box in real time and record the pressure data. The collected raw pressure data is preprocessed, including noise removal, filtering, etc., to improve the quality and accuracy of the data.
[0038] According to the control parameters and dustproof performance test targets, the pre-processed pressure data is analyzed. For example, the dustproof effect of the junction box under different pressure conditions is analyzed, and by comparing the data changes before and after the pressure is applied, it is evaluated whether the dustproof performance of the junction box meets the standard.
[0039] Step S500: collecting pressure interaction data, performing curve fitting on the pressure interaction data, performing sealing evaluation according to the trend of the fitting curve, and obtaining dustproof detection results.
[0040] In the embodiment of the present application, the pressure data in the junction box is first recorded in real time by a pressure sensor, and the collected raw pressure data is preprocessed, including removing abnormal values, smoothing, etc., to improve the data quality.
[0041] According to the characteristics of the data, select an appropriate curve fitting method, such as polynomial fitting, exponential fitting, or power function fitting. When selecting a fitting method, first analyze the characteristics of the pressure data. The distribution, periodicity, growth or decay trend of the data will affect the choice of fitting method. If the data shows a trend that can be described by a polynomial, such as rising first and then falling or there are multiple peaks and troughs, then choose polynomial fitting. When the data shows an exponential growth or decay trend, such as the pressure data changes rapidly at the beginning of the test and then stabilizes, choose exponential fitting.
[0042] After selecting the curve fitting method, use mathematical software or programming tools to perform curve fitting on the preprocessed pressure data. By adjusting the fitting parameters, the fitting curve can best reflect the trend of the original data.
[0043] The fitting curve is analyzed to obtain the slope, peak value and fluctuation of the curve. The sealing performance of the junction box is evaluated based on the characteristics of the fitting curve. For example, if the fitting curve remains stable and has small fluctuations during the test, it means that the sealing performance of the junction box is good; if the curve shows large fluctuations or a downward trend, it may indicate that the junction box has leakage or poor sealing.
[0044] According to relevant industry standards or design requirements, determine the evaluation criteria for dustproof performance. These standards include the maximum allowable pressure change range, leakage rate, etc.
[0045] Compare the analysis results of the fitting curve with the dustproof standard to determine whether the dustproof performance of the junction box meets the standard. If the sealing evaluation result of the junction box meets or exceeds the requirements of the dustproof standard, it can be considered that its dustproof performance is good; otherwise, it is considered that the dustproof performance does not meet the standard.
[0046] Through the above steps, the dustproof test results are obtained.
[0047] Furthermore, the method further comprises:
[0048] Acquire application environment monitoring data, wherein the application environment monitoring data includes pressure monitoring data and dust particle monitoring data;
[0049] Performing pressure value and dust particle size analysis on the pressure monitoring data and dust particle monitoring data to determine environmental pressure characteristics and environmental particle characteristics;
[0050] Constraint conditions are generated according to the environmental pressure characteristics and environmental particle characteristics, and control constraints are imposed on the control parameters.
[0051] In the embodiment of the present application, a pressure sensor is used to collect real-time data at the application location of the explosion-proof junction box, and the collected data includes information such as timestamp and pressure value. A dust particle detector is used to collect data at the same or similar environmental location. The dust concentration and particle size distribution in the air are recorded. The data also includes a timestamp.
[0052] After collecting the pressure monitoring data and dust particle monitoring data, the pressure monitoring data is cleaned and preprocessed, and then the average pressure, pressure fluctuation range, standard deviation and other statistics are calculated to describe the environmental pressure characteristics. Through time series analysis, it is determined whether there are periodic changes or abnormal fluctuations in the pressure monitoring data. Similarly, the dust particle monitoring data is preprocessed, and then the dust concentration changes and the statistical characteristics of the dust particle size distribution, such as the average particle size and the standard deviation of the particle size distribution, are analyzed.
[0053] If the pressure fluctuation exceeds the preset safety range, a constraint condition is generated to limit the maximum operating pressure of the equipment in this environment. When the dust concentration exceeds the safety standard, a constraint condition is generated to start the dust removal equipment or increase the ventilation volume to reduce the dust concentration.
[0054] According to the generated constraints, the control system parameters are automatically adjusted, such as the operating power of the equipment, the on / off status of the ventilation system, etc.
[0055] Furthermore, a sealing simulation test is performed on the structural information and the material information to determine a dustproof performance detection target, and the method further includes:
[0056] Configure preset structural feature annotations, including integrated structure, connection parts, and external interfaces, and perform feature recognition and annotation on the structural information of the explosion-proof junction box;
[0057] Performing sealing tests on the integrated structure, connection parts, and external interfaces respectively to obtain sealing test results of various structural features;
[0058] The sealing area of the explosion-proof junction box is obtained, and according to the sealing test results of the integrated structure, the connection parts, and the external interface, the sealing area is evaluated for sealing and the detection target is located to obtain the dustproof performance detection target, which is the structural part whose sealing evaluation result is lower than a preset threshold.
[0059] In the embodiment of the present application, first, the structural information of the explosion-proof junction box is identified and annotated in detail in the simulation environment. For the integrated structure, the main structure of the box, such as the side panels, top panels, bottom panels, etc., is clearly marked in the simulation model. For the connection parts, all connection points, such as welding points, screw connections, etc., are identified and accurately marked in the model. For external interfaces, all external ports, such as cable inlets, exhaust holes, etc., are clearly marked in the simulation model.
[0060] In a simulation environment, conduct a sealing test on the integrated structure of the explosion-proof junction box, such as the side panels, top panels, and bottom panels. By simulating the penetration of gas or liquid under different pressure conditions, observe whether there is leakage, and record the location and extent of the leakage. Conduct simulation tests on the connection parts of the explosion-proof junction box, such as welding points and screw connections. Apply stress and vibration in a simulated working environment, detect the sealing performance of the connection parts, and record any potential leakage points. Conduct a sealing simulation test on all external interfaces of the explosion-proof junction box, such as cable inlets and exhaust holes. By simulating the use of the interface under different environmental conditions, check its sealing effect, and record the leakage and related data.
[0061] Next, determine which areas inside the explosion-proof junction box are designed to be sealed based on the product's design specifications and usage requirements.
[0062] Compare the sealing test results with the preset sealing standards in the product design. The sealing standards are set based on the product's usage environment and expected performance to ensure that the product can maintain good sealing under normal working conditions.
[0063] For each area that needs to maintain a seal or a specific pressure, the sealing effect is evaluated based on the collected test data. Analyze whether the leakage rate is within the acceptable range and whether the pressure change meets the design requirements.
[0064] In order to locate the detection target of dustproof performance, a sealing threshold is set. This threshold should be determined based on the design requirements of the product and the actual use environment, ensuring that only areas below this threshold are considered as potential dustproof performance problem areas. By comparing the test results and the threshold, those sealing areas whose sealing performance is below the preset threshold are identified.
[0065] Ultimately, the dustproof performance testing targets are determined to be those structural parts whose sealing evaluation results are lower than the preset standards.
[0066] Furthermore, the method for configuring the control parameters of the pressure detection device further includes:
[0067] According to the material information, obtaining material compression resistance information;
[0068] Analyze the pressure influence relationship according to the structural feature annotation type to obtain the pressure resistance influence coefficient;
[0069] The material pressure resistance information is adjusted using the pressure resistance influence coefficient to obtain an output pressure threshold;
[0070] The output pressure threshold is screened according to the constraint condition to obtain the output pressure.
[0071] In the embodiment of the present application, firstly, the compressive information of the material, such as compressive strength, elastic modulus, etc., is obtained by consulting relevant material manuals and databases according to the material information.
[0072] Select the appropriate finite element analysis according to the specific structure of the explosion-proof junction box and the complexity of the required analysis. Set the loads in the simulation according to the actual situation, such as internal pressure, external pressure, etc. Set the constraints of the model, such as fixed supports, freedom restrictions, etc., to ensure the stability of the simulation. When performing the simulation, collect the deformation and stress distribution of each structural feature of the explosion-proof junction box under different pressure conditions. Record the key data in the simulation process, such as the maximum deformation variable, the maximum stress value, etc.
[0073] The data in the simulation results are sorted and analyzed to extract key indicators related to the structural features. Based on the extracted data, a compressive influence coefficient is calculated for each structural feature. This coefficient can be obtained by comparing the deformation and stress of different structural features under the same pressure. For example, if a structural feature has a smaller deformation and a more uniform stress distribution under the same pressure, its compressive influence coefficient may be higher.
[0074] When using the compression influence coefficient to adjust the material's compression information, the compression influence coefficient is applied to the original compression information of the material. Specifically, if the compression influence coefficient is greater than 1, it means that the structural feature enhances the material's compression resistance, so the original compression strength is multiplied by this coefficient to obtain the adjusted compression strength. Conversely, if the coefficient is less than 1, it means that the structural feature weakens the material's compression resistance, and corresponding adjustments are also required.
[0075] After adjusting the material's compressive strength information, the output pressure threshold is calculated based on the design requirements and safety margin. This threshold is lower than the adjusted compressive strength. Specifically, the original compressive strength is multiplied by the compressive influence coefficient, and the safety margin is subtracted to obtain the output pressure threshold. The safety margin can be a fixed value or a percentage of the adjusted compressive strength, which is set by professionals.
[0076] For the output pressure threshold, check whether all constraints are met. For example, simulate the deformation of the explosion-proof junction box under this pressure to check whether it exceeds the maximum allowable deformation; similarly, calculate the stress on the material under this pressure to see whether it exceeds the allowable stress of the material. If a candidate output pressure threshold does not meet the constraints, exclude it or adjust it according to the specific situation. For example, if the simulation finds that the deformation of the explosion-proof junction box exceeds the maximum allowable value under a certain pressure, lower the candidate output pressure threshold. After screening and adjusting all candidate output pressure thresholds, an output pressure threshold that meets all constraints and ensures the safe operation of the explosion-proof junction box is obtained. This pressure threshold is used as the output pressure.
[0077] Furthermore, the pressure interaction data is collected, a curve is fitted to the pressure interaction data, a sealing evaluation is performed according to the trend of the fitting curve, and a dustproof test result is obtained. The method also includes:
[0078] Deploying monitoring sensor equipment, including: arranging a pressure monitor in the sealing area, and deploying a leakage detector according to the dustproof performance detection target;
[0079] Acquire pressure monitoring data of the pressure monitor, perform curve fitting, and determine the pressure trend based on the pressure change trend curve;
[0080] When the pressure trend reaches a preset drop, a sealing abnormality result is generated and the leakage detector is activated;
[0081] The detection data of the leakage detector is acquired, the abnormal detection target is located, and the dust prevention detection result is generated.
[0082] In the embodiment of the present application, the positions of the pressure monitor and the leak detector are arranged according to the key sealing area and possible leakage points of the equipment. The pressure monitor is installed in the sealing area. The leak detector is configured at the possible leakage path or key connection to detect the leak in time when the pressure is abnormal.
[0083] According to actual needs, set the frequency of data collection of the pressure monitor, such as once per second, once per minute or once per hour.
[0084] After the monitoring sensors are deployed, monitor and clean and organize the collected pressure data to remove outliers and noise. Select appropriate curve fitting methods according to the characteristics of the data, such as linear fitting, polynomial fitting, etc. Use mathematical software or programming tools to perform curve fitting on the pressure data to generate a fitting curve. According to the shape and trend of the fitting curve, determine whether the pressure is stable, rising or falling.
[0085] The preset pressure drop is to set a reasonable pressure drop threshold based on historical data and actual needs. By real-time monitoring the trend of the fitting curve, once the pressure drop exceeds the preset threshold, it is determined to be a sealing abnormality. After the sealing abnormality is determined, the leak detector is immediately activated for detection. After that, the data detected by the leak detector is analyzed, and the specific location of the leak is determined by comparing the data changes at different detection points. According to the data analysis results, the leak point or abnormal area is accurately located.
[0086] Finally, the pressure monitoring data and leak detection data are integrated together to form a complete test report, namely the dust prevention test results. The dust prevention test results include the location of the leak point, the severity of the leak, etc.
[0087] Furthermore, when the pressure trend reaches a preset drop, a sealing abnormality result is generated, and after the leakage detector is activated, the method further includes:
[0088] According to the pressure trend, obtaining the pressure leakage amount;
[0089] According to the environmental pressure characteristics and the pressure leakage, a pressure difference configuration is performed to obtain a pressure compensation requirement;
[0090] According to the pressure trend and the pressure compensation requirement, parameters are decomposed in a time series manner to generate compensation pressure control parameters to perform output pressure compensation control on the pressure detection device.
[0091] In an embodiment of the present application, when the pressure trend is abnormal, that is, the pressure continues to drop and the drop exceeds a preset threshold, the leakage calculation program is triggered, the slope and time of the pressure change curve are integrated to determine the pressure leakage.
[0092] The atmospheric pressure outside the device is then monitored in real time through an external sensor, the pressure inside the device is compared with the ambient pressure, and the pressure difference between the two is calculated.
[0093] After obtaining the pressure difference and leakage data, the compensation requirement is determined according to the pressure difference and the leakage rate. In order to restore the sealing area to the initial pressure, real-time pressure compensation is determined, which is real-time injection to offset the pressure loss due to leakage. The pressure compensation requirement is determined through the above steps.
[0094] When performing time-series parameter decomposition based on pressure trends and pressure compensation requirements, the total compensation amount is decomposed into different time points according to the predicted pressure trends and compensation requirements. The compensation pressure value at each time point is determined to form a continuous compensation pressure sequence. The compensation pressure value obtained by time-series decomposition is converted into a control parameter that can be recognized by the device. The generated compensation pressure control parameter is sent to the pressure detection device. These devices automatically adjust their output pressure according to the received parameters to achieve the required compensation effect.
[0095] Furthermore, generating constraint conditions according to the environmental pressure characteristics and environmental particle characteristics, the method further includes:
[0096] Determine particle size and particle density according to the environmental particle characteristics;
[0097] Performing a pressure demand analysis based on the particle size and particle density to determine a pressure demand condition, wherein the pressure demand condition is a maximum pressure threshold and stability requirement to avoid particle blowing;
[0098] Performing a pressure demand analysis based on the environmental pressure characteristics to determine a pressure threshold of the environmental characteristics, wherein the pressure threshold is a minimum pressure threshold that satisfies the pressure difference between the environment and the internal pressure;
[0099] The pressure constraint condition is determined by fusing the pressure requirement condition with the pressure threshold of the environmental characteristic.
[0100] In the embodiment of the present application, the particle size and particle density are firstly extracted from the environmental particle characteristics.
[0101] Computer simulation software is used to simulate the motion state of particles under different pressures based on the particle size and density parameters. The pressure threshold at which particles start to move can be found through simulation. The sedimentation velocity of particles in a static fluid can be calculated based on the density and particle size of the particles. In order to ensure the stability of the particles, the pressure in the fluid needs to be kept low enough to prevent the particles from accelerating sedimentation or unstable flow due to excessive force. Fluid dynamics simulation software is used to analyze the motion state and stability of particles under different pressures, and a stable pressure range is determined to maintain uniform distribution and stable flow of particles.
[0102] Analyze the environmental pressure characteristics and determine the key indicators such as the range, average, maximum, and minimum values of the environmental pressure. Then determine the tolerance of the equipment to changes in external environmental pressure based on factors such as the equipment's design specifications, materials used, and sealing performance. Evaluate the risks of excessive pressure differences to the equipment. These risks include structural damage, performance degradation, and leakage.
[0103] According to the normal working pressure inside the equipment and the pressure data of the external environment, the pressure difference between the two is calculated. Based on the above process, a minimum pressure threshold is set.
[0104] Compare the maximum pressure threshold to avoid particle blowing and the pressure range required for stability with the minimum pressure threshold of the pressure difference between the environment and the interior. Based on the comparison, find a pressure range that meets all conditions. This range is lower than the maximum pressure threshold to avoid particle blowing, meets the stability requirement, and is not lower than the minimum pressure threshold of the pressure difference between the environment and the interior.
[0105] Finally, this pressure range is used as the pressure constraint.
[0106] Furthermore, according to the fusion of the pressure requirement condition and the pressure threshold of the environmental feature, the pressure constraint condition is determined, and the method further includes:
[0107] Configure the fusion priority of the pressure demand condition;
[0108] Based on the fusion priority of the pressure requirement condition, when there is a fusion anomaly between the pressure requirement condition and the pressure threshold of the environmental feature, the pressure requirement condition is prioritized for fusion;
[0109] According to the pressure threshold of the environmental characteristic and the pressure requirement condition, the pressure threshold of the environmental characteristic is decomposed and multi-level pressurization control information is set.
[0110] In the embodiment of the present application, the maximum pressure threshold for avoiding particle blowing is the primary condition for ensuring the normal operation of the equipment and preventing failures, and the maximum pressure threshold for avoiding particle blowing is taken as the highest priority.
[0111] When trying to merge the pressure requirement condition with the pressure threshold of the environmental feature, if a conflict or inconsistency is detected, it is considered a fusion anomaly. According to the previously set fusion priority, when an anomaly occurs, the pressure requirement condition is prioritized for fusion. That is, when formulating the constraint condition, the maximum pressure threshold requirement to avoid particle blowing is first met.
[0112] After determining the pressure threshold range of the environmental characteristics, the pressure requirement conditions are combined to further decompose this range. Specifically, the pressure threshold range of the environmental characteristics is divided into several small intervals or levels according to the maximum pressure threshold and stability requirements to avoid particle blowing. Each level should be a safe operating window that will not cause particles to be blown in and can meet the stability requirements of the system.
[0113] For example, suppose the maximum pressure threshold to avoid particle blowing is 1025 hPa, and the stability requirement is to operate optimally between 1010 and 1020 hPa. Then, the pressure threshold range of the environmental characteristics is decomposed into three levels: 1000-1010 hPa, 1010-1020 hPa, and 1020-1025 hPa.
[0114] When decomposing the pressure thresholds of environmental features, ensure that the upper limit of each level does not exceed the maximum pressure threshold to avoid particle blowing, and that the lower and upper limits of each level meet the stability requirements of the system.
[0115] According to the decomposed pressure level, specific pressurization control parameters are set for each level. These parameters include but are not limited to pressurization speed, pressurization time, and stabilization time after reaching each level.
[0116] For example, for the 1010-1020 hPa level, set the pressurization speed to 1 hPa per minute, the pressurization time to 10 minutes, and the stabilization time to 5 minutes. This means that when the system needs to adjust to this pressure level, it will increase the pressure at a rate of 1 hPa per minute until it reaches 1020 hPa, and then run steadily at this pressure level for 5 minutes.
