[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0022] 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 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, please refer to Figure 1-Figure 5 , this embodiment provides the following technical solutions: Embodiment 1

[0023] 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.

[0024] 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 each other.

[0025] It should be noted that the first drawer 1 and the second drawer 2 are hooked together to form a snap connection through the first hook 11 and the second hook 21. When taking out and replacing the activated carbon, the first drawer 1 is first pulled out, and then the first hook 11 of the first drawer 1 is hooked on the second hook 21 of the second drawer 2 to further pull out the second drawer 2, making it more convenient to pull out. Embodiment 2

[0026] In order to better demonstrate the principle of online monitoring of the bottom deformation of an activated carbon box drawer, the present embodiment provides an online monitoring system for the bottom deformation of an activated carbon box drawer, which is used to online monitor the deformation of the bottom of a drawer connected using the activated carbon box drawer connection structure as described above, including: an online acquisition module, a data processing module, a monitoring and analysis module, and an early warning management module.

[0027] 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 deformation of the drawer bottom; In this embodiment, the online acquisition module includes: The strain gauge sensor is used to install the strain gauge sensor at the bottom of the activated carbon box drawer, and to monitor and collect the stress changes at the bottom of the activated carbon box drawer in real time based on the strain gauge sensor to obtain the stress data at the bottom of the activated carbon box drawer; 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.

[0028] A piezoelectric sensor is used to install a piezoelectric sensor at the bottom of the activated carbon box drawer, and to monitor and collect the pressure changes at the bottom of the activated carbon box drawer in real time based on the piezoelectric sensor to obtain the pressure data at the bottom of the activated carbon box drawer; 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 is deformed.

[0029] A displacement sensor is used to install the displacement sensor at the bottom of the activated carbon box drawer, and to monitor and collect the displacement changes of the bottom of the activated carbon box drawer in real time based on the displacement sensor to obtain the displacement data of the bottom of the activated carbon box drawer; 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.

[0030] 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 online monitoring of the deformation of the bottom of the drawer is determined.

[0031] The data processing module is used to clean, convert and integrate the real-time data of online monitoring of drawer bottom deformation, and to safely store the integrated real-time data of online monitoring of drawer bottom deformation; Specifically, a piezoelectric sensor is installed at the bottom of the activated carbon box drawer, including: Perform 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; The area corresponding to the bottom of the activated carbon box drawer is equivalent to a rectangular area; Extracting the sensitivity corresponding to the piezoelectric sensor; Obtaining the side length of the grid according to the sensitivity corresponding to the piezoelectric sensor and the side length of the rectangular area; The grid side length is obtained by the following formula:

[0032] Where D represents the length of the grid side; 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; 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; A piezoelectric sensor is arranged at each grid interval; wherein the piezoelectric sensor is arranged at the center point of the grid corresponding to the piezoelectric sensor; The integrated pressure value corresponding to the bottom of the activated carbon box drawer is obtained according to the pressure data of the bottom of the activated carbon box drawer collected by multiple piezoelectric sensors.

[0033] The technical effect of the above technical solution is: by extracting the bottom graphics of the bottom of the activated carbon box drawer and equating it to a rectangular area, the technical solution can more accurately determine the layout of the piezoelectric sensor. This layout method not only simplifies the installation process, but also ensures that the sensor can evenly cover the entire bottom area, thereby improving the accuracy and comprehensiveness of pressure data acquisition. The grid side length is determined according to the sensitivity of the piezoelectric sensor and the side length of the rectangular area, which fully considers the performance characteristics and regional characteristics of the sensor. In this way, it can be ensured that the pressure changes in each grid can be accurately captured by the sensor, thereby improving the accuracy of data acquisition. The technical solution introduces a preset sensitivity reference value so that the system can adjust the layout density of the sensor according to actual conditions. When the pressure distribution or pressure size at the bottom of the activated carbon box drawer changes, the system can adapt to these changes by adjusting the grid side length, thereby ensuring the accuracy and reliability of data acquisition. By setting a piezoelectric sensor for each grid interval, the technical solution effectively reduces the number of sensors used while ensuring the accuracy of data acquisition. This not only reduces the hardware cost of the system, but also simplifies the maintenance and management of the system. The data collected by multiple piezoelectric sensors can more comprehensively reflect the pressure distribution at the bottom of the activated carbon box drawer. By processing these data with a reasonable algorithm, an accurate comprehensive pressure value can be obtained, which can truly reflect the overall pressure state at the bottom of the activated carbon box drawer. Since this technical solution adopts a grid layout and interval sensor arrangement, even if a sensor fails or is damaged, it will not have much impact on the data collection and calculation of the entire system. This redundant design enhances the reliability and stability of the system.

[0034] 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 cost, improving the accuracy of comprehensive pressure value calculation, and enhancing system reliability and stability.

[0035] 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: Compare the pressure data value collected by each piezoelectric sensor with a preset pressure data threshold; 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; When there is only one piezoelectric sensor corresponding to the pressure data value exceeding the preset pressure data threshold, the piezoelectric sensor corresponding to the pressure data value exceeding the preset pressure data threshold is used as the target piezoelectric sensor; 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; The piezoelectric sensors corresponding to the collected data of the non-zero pressure data values ​​other than the target piezoelectric sensor are used as observation piezoelectric sensors; Extracting the pressure data value corresponding to the target piezoelectric sensor and the pressure data value of each observed piezoelectric sensor; Extracting the straight-line distance between each observed piezoelectric sensor and the target piezoelectric sensor; Obtain a comprehensive pressure value using the pressure data value corresponding to the target piezoelectric sensor and the pressure data value of each observed piezoelectric sensor in combination with the straight-line distance between each observed 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; The comprehensive pressure value is obtained by the following formula:

[0036] Wherein, 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 angle 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; x represents the base of the logarithmic function.

[0037] The technical effect of the above technical solution is: by comparing the preset pressure data threshold, abnormal or significant pressure data points can be screened out, thereby ensuring that the data processed subsequently is representative. When there are multiple sensors exceeding the threshold, the maximum value is selected as the target piezoelectric sensor, which helps to capture the maximum pressure point at the bottom of the activated carbon box drawer and improve the accuracy of the data. When calculating the comprehensive pressure value, not only the pressure data value of the target piezoelectric sensor is considered, but also the pressure data value of the observed piezoelectric sensor, the straight-line distance between them and the target sensor, the standard deviation of the pressure data value, and the standard deviation of the position angle are combined. This comprehensive consideration method can more comprehensively reflect the pressure distribution at the bottom of the activated carbon box drawer and improve 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 direction of the rectangular area, the uniformity of the sensor layout and the directionality of the pressure distribution can be reflected. This helps to identify whether there is a situation of local pressure concentration or uneven pressure distribution, and provides strong support for subsequent fault analysis or optimization. Introducing a logarithmic function in the calculation formula of the comprehensive pressure value can make the impact of the change in pressure data on the comprehensive pressure value smoother and avoid the excessive impact of extreme values ​​on the results. At the same time, the logarithmic function can also amplify the difference between smaller pressure values ​​and improve the resolution of the data. This technical solution can be applied to the bottom of activated carbon box drawers of different sizes and shapes. It only needs to adjust the size of the rectangular area and the layout of the sensor according to the actual situation. In addition, by adjusting the preset pressure data threshold and the parameters in the formula, it can further adapt to different application scenarios and needs. Since multiple piezoelectric sensors are used for data collection and the comprehensive pressure value is obtained through the above algorithm processing, even if a sensor fails or the data is abnormal, it will not have much impact on the reliability and accuracy of the entire system. This redundant design improves the stability and reliability of the system.

[0038] In summary, this technical solution improves the accuracy and reliability of the pressure data at the bottom of the activated carbon box drawer by comprehensively considering multiple factors, introducing the position angle standard deviation and logarithmic function, etc., and provides strong support for subsequent fault analysis, optimization and maintenance. At the same time, this solution also has strong adaptability and system reliability, and can be applied to different application scenarios and needs.

[0039] In this embodiment, the data processing module includes: A data cleaning unit, used to clean the real-time data of online monitoring of drawer bottom deformation; Among them, the real-time data of online monitoring of drawer bottom deformation is checked based on data processing tools, and duplicate values, missing values ​​and abnormal values ​​in the real-time data of online monitoring of drawer bottom deformation that are of no value to the online monitoring of the drawer bottom deformation of the activated carbon box are identified; For the duplicate values ​​that are identified as having no value for the online monitoring of the deformation of the bottom of the drawer of the activated carbon box, the duplicate values ​​are deleted, and the only record in the real-time data of the online monitoring of the deformation of the bottom of the drawer is retained; For the missing values ​​that are identified as having no value for the online monitoring of the deformation of the bottom of the activated carbon box drawer, the missing values ​​are deleted or filled to make the missing values ​​complete; For the outliers that are identified as having no value for the online monitoring of the deformation of the bottom of the activated carbon box drawer, the outliers are deleted or replaced to make them normal.

[0042] Among them, the early warning management module is used to provide abnormal early warning and intelligent management and control of activated carbon box drawers that are at risk of deformation, so that management personnel can promptly pull out and replace the activated carbon box drawers that are at risk of deformation.
