The activated carbon set in the activated carbon box drawer is used to absorb the waste gas generated during the production of the enterprise. Among them, when the activated carbon box drawer holds activated carbon, the bottom of the activated carbon box drawer is easily deformed due to the pressure of the activated carbon, making it difficult to take out the activated carbon box drawer, which in turn affects the subsequent use of the activated carbon box.

[0003] Existing technology cannot perform real-time online monitoring of the deformation of the bottom of the activated carbon box drawer, resulting in the inability to timely detect the deformation of the bottom of the activated carbon box drawer, and the inability to timely pull out and replace the activated carbon box drawer that has the risk of deformation, resulting in poor use of the activated carbon box drawer.

[0070] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0071] In order to solve the existing problem that the deformation of the bottom of the activated carbon box drawer cannot be monitored online in real time, resulting in the inability to detect the deformation of the bottom of the activated carbon box drawer in time, and the inability to pull out and replace the activated carbon box drawer with deformation risk in time, resulting in poor use of the activated carbon box drawer, please refer to Figure 1-Figure 5 , this embodiment provides the following technical solutions: Example 1

[0072] The activated carbon box drawer connection structure includes a first drawer 1 and a second drawer 2. The first drawer 1 is provided with a first hook 11 extending outward at one end close to the second drawer 2, and the second drawer 2 is provided with a second hook 21 extending outward at one end close to the first drawer 1. The first drawer 1 and the second drawer 2 are hooked together by the first hook 11 and the second hook 21 to form a snap connection.

[0073] In this embodiment, after the first drawer 1 and the second drawer 2 are snap-connected, the first drawer 1 and the second drawer 2 fit together.

[0074] It should be noted that the first drawer 1 and the second drawer 2 are hooked together by the first hook 11 and the second hook 21 to form a snap connection. When taking out and replacing the activated carbon, first pull out the first drawer 1, and then use the first hook 11 of the first drawer 1 to hook the second hook 21 of the second drawer 2 and then pull out the second drawer 2, making it more convenient to pull out. Example 2

[0075] In order to better demonstrate the principle of online monitoring of the deformation of the bottom of the activated carbon box drawer, this embodiment now provides an online monitoring system for the deformation of the bottom of the activated carbon box drawer, which is used to online monitor the deformation of the bottom of the drawer connected using the above-mentioned activated carbon box drawer connection structure, including: an online acquisition module, a data processing module, a monitoring and analysis module and an early warning management module.

[0076] Among them, the online acquisition module is used to collect stress, pressure and displacement data at the bottom of the activated carbon box drawer, and determine the real-time online monitoring data of the drawer bottom deformation;

[0077] In this embodiment, the online acquisition module includes:

[0078] A strain gauge sensor is installed at the bottom of the activated carbon box drawer to monitor and collect stress changes at the bottom of the activated carbon box drawer in real time based on the strain gauge sensor, thereby obtaining stress data at the bottom of the activated carbon box drawer;

[0079] It should be noted that the strain gauge sensor is a commonly used measuring tool used to detect the strain at the bottom of the activated carbon box drawer. The strain gauge is made of a sensitive material. When the bottom of the activated carbon box drawer is subjected to force or pressure, the strain gauge will deform and its resistance value will change. By measuring this resistance change, the strain at the bottom of the activated carbon box drawer can be calculated.

[0080] A piezoelectric sensor is installed at the bottom of the activated carbon box drawer to monitor and collect pressure changes at the bottom of the activated carbon box drawer in real time based on the piezoelectric sensor, thereby obtaining pressure data at the bottom of the activated carbon box drawer;

[0081] It should be noted that the piezoelectric sensor is installed on the bottom of the activated carbon box drawer to detect the pressure changes on the bottom of the activated carbon box drawer. When the bottom of the activated carbon box drawer is deformed, stress will be generated on its surface, causing the piezoelectric sensor to sense the corresponding pressure changes. By monitoring the voltage signal output by the piezoelectric sensor, the stress and deformation of the bottom of the activated carbon box drawer can be understood. If the voltage signal changes significantly, it means that the bottom of the activated carbon box drawer has been deformed.

[0082] A displacement sensor is installed at the bottom of the activated carbon box drawer to monitor and collect displacement changes of the bottom of the activated carbon box drawer in real time based on the displacement sensor, thereby obtaining displacement data of the bottom of the activated carbon box drawer;

[0083] It should be noted that the displacement sensor is a sensor used to detect the position change of the bottom of the activated carbon box drawer. It can convert the displacement of the bottom of the activated carbon box drawer relative to a certain reference point into a corresponding electrical signal output. By monitoring the electrical signal output by the displacement sensor, it is possible to indirectly understand whether the bottom of the activated carbon box drawer has been deformed.

[0084] Among them, based on the stress data of the bottom of the activated carbon box drawer, the pressure data of the bottom of the activated carbon box drawer and the displacement data of the bottom of the activated carbon box drawer, the real-time data of the online monitoring of the deformation of the drawer bottom is determined.

[0085] The data processing module is used to clean, convert and integrate the real-time data of online monitoring of drawer bottom deformation, and to securely store the integrated real-time data of online monitoring of drawer bottom deformation;

[0086] Specifically, a piezoelectric sensor is installed at the bottom of the activated carbon box drawer, including:

[0087] Performing bottom graphics extraction on the bottom of the activated carbon box drawer to obtain an area corresponding to the bottom of the activated carbon box drawer;

[0088] Equivalently convert the area corresponding to the bottom of the activated carbon box drawer into a rectangular area;

[0089] Extracting the sensitivity corresponding to the piezoelectric sensor;

[0090] Obtaining the side length of the grid according to the sensitivity corresponding to the piezoelectric sensor and the side length of the rectangular area;

[0091] The grid side length is obtained by the following formula:

[0092] Where D represents the grid side length; W represents the width of the rectangular area; L represents the length of the rectangular area; S represents the sensitivity of the piezoelectric sensor; S m Indicates the preset sensitivity reference value; A s Indicates the actual area of ​​the bottom of the activated carbon box drawer; A x Represents the area corresponding to the rectangular area;

[0093] Divide the area corresponding to the bottom of the activated carbon box drawer into grids according to the side length of the grids to obtain multiple grids;

[0094] A piezoelectric sensor is set at each grid interval; wherein the piezoelectric sensor is set at the grid center point of its corresponding grid;

[0095] The integrated pressure value corresponding to the bottom of the activated carbon box drawer is obtained based on the pressure data of the bottom of the activated carbon box drawer collected by multiple piezoelectric sensors.

[0096] The technical solution described above achieves the following: By extracting the bottom geometry of the activated charcoal drawer and equating it to a rectangular area, the system can more accurately determine the layout of the piezoelectric sensors. This layout not only simplifies the installation process but also ensures uniform sensor coverage across the entire bottom area, thereby improving the accuracy and comprehensiveness of pressure data collection. The grid dimensions are determined based on the piezoelectric sensor sensitivity and the rectangular area's side length, fully considering the sensor's performance characteristics and regional characteristics. This ensures that pressure changes within each grid are accurately captured by the sensor, thereby improving data collection accuracy. By introducing a preset sensitivity reference value, the system can adjust the sensor layout density based on actual conditions. When the pressure distribution or pressure level at the bottom of the activated charcoal drawer changes, the system can adapt to these changes by adjusting the grid side length, thereby ensuring accurate and reliable data collection. By placing a piezoelectric sensor every other grid, the solution effectively reduces the number of sensors used while ensuring data collection accuracy. This not only reduces the system's hardware cost but also simplifies system maintenance and management. Data collected by multiple piezoelectric sensors provides a more comprehensive picture of the pressure distribution at the bottom of the activated charcoal drawer. By processing this data with a rational algorithm, an accurate composite pressure value can be derived, truly reflecting the overall pressure state at the bottom of the activated charcoal drawer. Because this technical solution utilizes a grid layout and spaced sensors, even if a sensor fails or is damaged, it will not significantly impact the overall system's data collection and calculations. This redundant design enhances system reliability and stability.

[0097] In summary, this technical solution provides an efficient, accurate and reliable solution for pressure monitoring at the bottom of the activated carbon box drawer by optimizing sensor layout, improving data acquisition accuracy, enhancing system adaptability, reducing system costs, improving the accuracy of comprehensive pressure value calculation, and enhancing system reliability and stability.

[0098] Specifically, the method of obtaining the integrated pressure value corresponding to the bottom of the activated carbon box drawer according to the pressure data of the bottom of the activated carbon box drawer collected by multiple piezoelectric sensors includes:

[0099] Comparing the pressure data value collected by each piezoelectric sensor with a preset pressure data threshold;

[0100] When the pressure data value collected by any piezoelectric sensor exceeds the preset pressure data threshold, the non-zero pressure data values ​​collected by all current piezoelectric sensors are retrieved;

[0101] When the pressure data value exceeds the preset pressure data threshold and the corresponding piezoelectric sensor is one, the piezoelectric sensor corresponding to the pressure data value exceeding the preset pressure data threshold is used as the target piezoelectric sensor;

[0102] When there are multiple piezoelectric sensors corresponding to the pressure data value exceeding the preset pressure data threshold, the piezoelectric sensor corresponding to the maximum pressure data value is used as the target piezoelectric sensor;

[0103] The piezoelectric sensors corresponding to the non-zero pressure data values ​​of the collected data other than the target piezoelectric sensor are used as observation piezoelectric sensors;

[0104] Extracting the pressure data value corresponding to the target piezoelectric sensor and the pressure data value of each observation piezoelectric sensor;

[0105] Extracting the straight-line distance between each observation piezoelectric sensor and the target piezoelectric sensor;

[0106] Obtain a comprehensive pressure value using the pressure data value corresponding to the target piezoelectric sensor and the pressure data value of each observation piezoelectric sensor in combination with the straight-line distance between each observation piezoelectric sensor and the target piezoelectric sensor, and use the comprehensive pressure value as the pressure data of the bottom of the activated carbon box drawer;

[0107] The comprehensive pressure value is obtained by the following formula:

[0108] Among them, P represents the comprehensive pressure value; P m represents the pressure data value corresponding to the target piezoelectric sensor; n represents the number of observed piezoelectric sensors; P i represents the pressure data value corresponding to the i-th observed piezoelectric sensor; P b represents the standard deviation of the pressure data values ​​corresponding to n observed piezoelectric sensors; θ b represents the standard deviation of the angles between the positions corresponding to the n observed piezoelectric sensors and the length direction of the rectangular area; θ i represents the angle between the position corresponding to the i-th observed piezoelectric sensor and the length direction of the rectangular area; d i represents the straight-line distance between the position corresponding to the i-th observed piezoelectric sensor and the target piezoelectric sensor; W represents the width of the rectangular area; and x represents the base of the logarithmic function.

[0109] The technical solution described above has the following advantages: By comparing pressure data against a preset threshold, abnormal or significant pressure data points can be screened out, ensuring representative data for subsequent processing. When multiple sensors exceed the threshold, the maximum value is selected as the target piezoelectric sensor. This helps capture the maximum pressure point at the bottom of the activated charcoal drawer, improving data accuracy. The calculation of the integrated pressure value not only considers the pressure data from the target piezoelectric sensor, but also incorporates multiple factors, including the pressure data from the observed piezoelectric sensor, the linear distance between the sensor and the target sensor, the standard deviation of the pressure data, and the standard deviation of the angle between the two sensors. This comprehensive approach provides a more comprehensive picture of the pressure distribution at the bottom of the activated charcoal drawer, improving the comprehensiveness and reliability of the data. By calculating the standard deviation of the angle between the corresponding position of the observed piezoelectric sensor and the length of the rectangular area, the uniformity of the sensor layout and the directionality of the pressure distribution can be reflected. This helps identify localized pressure concentrations or uneven pressure distribution, providing strong support for subsequent fault analysis or optimization. Introducing a logarithmic function into the integrated pressure calculation formula smoothes the impact of pressure data changes on the integrated pressure value, preventing extreme values ​​from overly influencing the results. At the same time, the logarithmic function can amplify differences between smaller pressure values, improving data resolution. This technical solution can be adapted to activated carbon drawer bottoms of varying sizes and shapes by simply adjusting the size of the rectangular area and the sensor layout based on the actual situation. Furthermore, by adjusting the preset pressure data thresholds and parameters in the formula, it can be further adapted to different application scenarios and needs. Because multiple piezoelectric sensors are used for data collection and the aforementioned algorithm is used to generate a composite pressure value, even if a sensor fails or the data is abnormal, it will not significantly affect the reliability and accuracy of the entire system. This redundant design improves the stability and reliability of the system.

[0110] In summary, this technical solution, by comprehensively considering multiple factors and introducing methods such as position angle standard deviation and logarithmic functions, improves the accuracy and reliability of activated carbon box drawer bottom pressure data, providing strong support for subsequent fault analysis, optimization, and maintenance. Furthermore, this solution offers strong adaptability and system reliability, making it suitable for diverse application scenarios and needs.

[0129] When the real-time data of the online monitoring of the deformation of the drawer bottom is within the threshold data range of the online monitoring of the deformation of the drawer bottom, the online monitoring analysis result of the deformation of the activated carbon box drawer bottom is that there is no deformation risk at the bottom of the activated carbon box drawer;

[0130] When the real-time data of the online monitoring of the deformation of the drawer bottom is not within the data range of the online monitoring threshold of the deformation of the drawer bottom, the online monitoring analysis result of the deformation of the drawer bottom of the activated carbon box is that there is a risk of deformation at the bottom of the drawer of the activated carbon box.
