[0123] The first data acquisition adjustment coefficient acquisition module is used to acquire the first data acquisition adjustment coefficient according to the data acquisition time and the maximum acquisition time deviation of the size acquisition unit, the weight acquisition unit, the shape acquisition unit, the structure acquisition unit and the material acquisition unit; wherein the first data acquisition adjustment coefficient is acquired by the following formula:

[0124]

[0125] Among them, K 01 represents the first data acquisition adjustment coefficient; n represents the number of data acquisition units, that is, n=5; t pi represents the maximum collection time deviation corresponding to the i-th data collection unit among the size collection unit, weight collection unit, shape collection unit, structure collection unit and material collection unit; t p represents the average data collection duration corresponding to n data collection units; k 01 and k 02 represent the first adjustment coefficient and the second adjustment coefficient respectively, and the first adjustment coefficient and the second adjustment coefficient are obtained by the following formula:

[0129] The second data acquisition adjustment coefficient acquisition module is used to extract the data acquisition time interval of the size acquisition unit, the weight acquisition unit, the shape acquisition unit, the structure acquisition unit and the material acquisition unit, and acquire the second data acquisition adjustment coefficient according to the data acquisition time interval of the size acquisition unit, the weight acquisition unit, the shape acquisition unit, the structure acquisition unit and the material acquisition unit; wherein the second data acquisition adjustment coefficient is acquired by the following formula:

[0130]

[0131] Among them, K 02 represents the second data acquisition adjustment coefficient; t max Indicates the maximum value of the data collection time interval among n data collection units; t pmax Indicates the maximum collection time deviation of the data collection unit corresponding to the maximum data collection time interval; t min Indicates the minimum value of the data collection time interval among n data collection units; t pmin Indicates the maximum collection time deviation of the data collection unit corresponding to the minimum data collection time interval;

[0132] The data collection time interval adjustment module is used to adjust the data collection time intervals of the size collection unit, the weight collection unit, the shape collection unit, the structure collection unit and the material collection unit by using the first data collection adjustment coefficient and the second data collection adjustment coefficient.

[0133] The technical effect of the above technical solution is that through the first data information extraction module and the second data information extraction module, the solution can accurately obtain key parameters such as the speed, speed deviation, and data collection volume of each data collection unit. The data information acquisition module uses these parameters to calculate the single data collection time and the maximum collection time deviation of each data collection unit, providing an accurate data basis for subsequent adjustments.

[0134] The first data acquisition adjustment coefficient acquisition module calculates the first data acquisition adjustment coefficient based on the acquisition time of each data acquisition unit and the maximum acquisition time deviation. This coefficient reflects the balance of the data acquisition time of each unit. The second data acquisition adjustment coefficient acquisition module takes into account the data acquisition time interval and further calculates the second data acquisition adjustment coefficient. This coefficient reflects the impact of the data acquisition time interval on synchronization. These two adjustment coefficients act together on the data acquisition time interval adjustment module to realize the intelligent adjustment of the time interval of each data acquisition unit, thereby improving the synchronization of data acquisition.

[0135] By precisely adjusting the time interval of each data acquisition unit, the solution can ensure that all data acquisition units complete data acquisition at similar time points, thereby improving the overall data acquisition efficiency. At the same time, it reduces data acquisition delays or omissions caused by improper time interval settings, thereby improving the accuracy of data collection. By dynamically adjusting the data collection time interval, the solution enables the system to flexibly respond to performance differences between different data acquisition units and real-time changing working environments. This flexibility ensures that the system can maintain efficient and accurate data collection capabilities under various circumstances.

[0136] In summary, this technical solution optimizes the synchronization, efficiency and accuracy of data collection by intelligently adjusting the data collection time interval, while enhancing the flexibility and adaptability of the system.

[0137] Specifically, the data collection time interval adjustment module includes:

[0138] A coefficient data extraction module, used to extract the first data acquisition adjustment coefficient and the second data acquisition adjustment coefficient;

[0139] A collection operation data extraction module is used to extract the maximum actual deviation of the collection speed of a single data collection of the size collection unit, the weight collection unit, the shape collection unit, the structure collection unit and the material collection unit;

[0140] A comprehensive adjustment coefficient acquisition module is used to obtain a comprehensive adjustment coefficient based on the maximum actual deviation of the acquisition speed of a single data acquisition of the size acquisition unit, the weight acquisition unit, the shape acquisition unit, the structure acquisition unit and the material acquisition unit in combination with the first data acquisition adjustment coefficient and the second data acquisition adjustment coefficient; wherein the comprehensive adjustment coefficient is obtained by the following formula:

[0141]

[0142] Wherein, g represents the comprehensive adjustment coefficient; m represents the number of single data collections corresponding to the size collection unit, weight collection unit, shape collection unit, structure collection unit and material collection unit; v j represents the theoretical data acquisition speed corresponding to the jth single data acquisition; v sj represents the actual data acquisition speed corresponding to the jth single data acquisition; v p Indicates the maximum speed deviation corresponding to the size collection unit, weight collection unit, shape collection unit, structure collection unit or material collection unit; K 01 represents the first data acquisition adjustment coefficient; K 02 represents the second data collection adjustment coefficient;

[0143] The data collection time interval adjustment module is used to adjust the data collection time interval of the size collection unit, the weight collection unit, the shape collection unit, the structure collection unit and the material collection unit by using the comprehensive adjustment coefficient, wherein the adjusted data collection time interval is obtained by the following formula:

[0144]

[0145] Among them, T g represents the adjusted data collection time interval; g represents the comprehensive adjustment coefficient; T y Indicates the data collection time interval before adjustment.

[0146] The technical effect of the above technical solution is: by introducing the coefficient data extraction module and the acquisition operation data extraction module, the technical solution can dynamically adjust the time interval of data acquisition according to the actual operation data (especially the deviation of the acquisition speed) of each data acquisition unit (size, weight, shape, structure, material). This adaptive adjustment mechanism ensures the accuracy and efficiency of data acquisition and reduces the problem of oversampling or undersampling caused by fixed time intervals. Through the comprehensive adjustment coefficient acquisition module, the comprehensive adjustment coefficient g is calculated by combining the theoretical data acquisition speed, the actual data acquisition speed, the maximum speed deviation and the two data acquisition adjustment coefficients (K01 and K02). This coefficient not only takes into account the deviation of a single data acquisition, but also weights it through the adjustment coefficient, making the adjustment more accurate and flexible.

[0147] By adjusting the data collection time interval (Tg), this technical solution can optimize the frequency of data collection according to the actual operating conditions. When the collection speed deviation is large, the sampling frequency is increased by shortening the time interval, and vice versa, it is appropriately extended, thereby effectively saving system resources and time while ensuring data quality. Dynamic adjustment of the data collection time interval helps to avoid overload or idle state during data collection, reduces system errors or performance degradation caused by improper data collection, and thus improves the stability and reliability of the entire system. Through modular design, this technical solution makes each functional module relatively independent, easy to implement and maintain. At the same time, the introduction of the adjustment coefficient also provides a flexible adjustment method, which is convenient for customization and optimization according to different application scenarios and needs.

[0148] In summary, this technical solution achieves the adaptability and accuracy of data collection by dynamically adjusting the data collection time interval, optimizes the data collection efficiency, and improves the stability and reliability of the system. It is of great significance for application scenarios that require high-precision and high-efficiency data collection.
