It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0028] Example 1
[0029] Figure 1This is a flowchart illustrating an error correction method for vibration sensor data according to Embodiment 1 of the present invention. This embodiment is applicable to the field of nuclear power plant applications, specifically for error correction of sensor data collected by a vibration sensor array. This method can be executed by an error correction device for vibration sensor data, which can be implemented in hardware and / or software and can be configured in various general-purpose computing devices. For example... Figure 1 As shown, the method includes:
[0030] S110. Acquire historical vibration signal data of the target sensor group, and based on the operating condition data and sensor error range data, perform data aggregation analysis on the historical vibration signal data to determine the vibration characteristic data of the target sensor group.
[0031] The target sensor group can be a sensor group to be corrected for errors. This group includes at least two vibration sensors, deployed in different locations to monitor vibrations in different dimensions of the target equipment. It should be noted that the target equipment can refer to nuclear power equipment.
[0032] Operating condition data can characterize the operating conditions of a vibration sensor when it is in operation, and may include the location of the vibration source, the number of vibration sources, the temperature of the environment and the target device, and the structural dimensions of the target device.
[0033] Sensor error range data refers to the standard error range that a vibration sensor is allowed to tolerate. It should be noted that different types of vibration sensors may have different corresponding sensor error range data.
[0034] Vibration characteristic data can be used to characterize the allowable error range of vibration signal data collected by the target sensor group under different operating conditions.
[0035] In this embodiment of the invention, the target sensor group itself consists of multiple vibration sensors capable of measuring different dimensions, acquiring vibration signals generated by the vibration source in different dimensions and directions. However, vibration sensors themselves have a limited lifespan, and therefore, errors may occur in the acquired vibration data when the lifespan is nearing its limit. Typically, this error is addressed by replacing or repairing the vibration sensor after the error is fully determined. However, this approach can easily cause discontinuity in monitoring vibration sensors used for real-time monitoring of nuclear power equipment, affecting the monitoring effect. Furthermore, the error of vibration sensors, especially those nearing their lifespan, has a stable directionality and may not necessarily require repair or replacement; monitoring can continue by reasonably correcting the collected data.
[0036] S120. Collect real-time vibration signal data of the target sensor group, and perform data error analysis on the real-time vibration signal data based on the vibration correlation characteristic data of the target sensor group.
[0037] Optionally, based on the vibration correlation characteristic data of the target sensor group, data error analysis is performed on the real-time vibration signal data, including: determining the vibration characteristic data corresponding to each vibration sensor in the target sensor group based on the vibration characteristic data of the target sensor group; and determining whether the real-time vibration signal data conforms to the vibration characteristic data corresponding to its respective vibration sensor.
[0038] Specifically, by identifying the vibration characteristic data of each vibration sensor in the target sensor group under different operating conditions, and based on the sensor type and operating condition of the vibration sensor to which the real-time collected vibration characteristic data belongs, it can be determined whether the real-time collected vibration signal data is within the data range represented by the vibration characteristic data.
[0039] S130. Correct the data error of the real-time vibration signal data based on the data error analysis results.
[0040] Optionally, in this embodiment of the invention, the error-corrected real-time vibration signal data can be used as historical vibration signal data to expand the historical vibration signal data, providing a rich data source for determining vibration characteristic data and improving the accuracy of vibration characteristic data.
[0041] The technical solution of this invention determines the vibration characteristic data of the target sensor group by performing correlation analysis on the historical vibration signal data of the target sensor group based on operating conditions. Then, based on the vibration correlation characteristic data, error analysis is performed on the real-time vibration signal data of the target sensor group, and error correction is performed on the real-time vibration signal data based on the error analysis results. This ensures the accuracy of the acquired data and avoids the impact on the analysis of the operating status of the monitoring equipment caused by the discontinuous vibration data acquisition due to the removal of equipment under unreasonable or inappropriate circumstances. This improves the effectiveness and stability of continuous monitoring of the monitoring equipment.
[0042] Example 2
[0043] Figure 2 This is a flowchart of a vibration sensor data error correction method provided in Embodiment 2 of the present invention. This embodiment further refines the above embodiment, providing specific steps for performing data aggregation analysis on the historical vibration signal data based on operating condition data and sensor error range data to determine the vibration characteristic data of the target sensor group. It should be noted that for parts not described in detail in this embodiment, please refer to the relevant descriptions in other embodiments, which will not be repeated here. Figure 2 As shown, the method includes:
[0044] S210. Based on the operating condition data, divide the historical vibration signal data of the target sensor into operating conditions and determine at least one group of historical vibration signal data for each operating condition.
[0045] In this embodiment of the invention, the sensor data (vibration signal values) collected by the vibration sensor within the theoretically permissible or collectable range are not discrete. Therefore, a linear relationship can be determined for the discrete sensor data collected by the vibration sensor. However, the operating conditions of the vibration sensor will affect the sensor data collected to some extent. Therefore, the sensor data can be clustered according to the operating conditions of the vibration sensor to obtain continuous historical vibration signal data collected by the vibration sensor under different operating conditions, so as to ensure that the clustered historical vibration signal data have obvious correlation characteristics.
[0046] It should be noted that the vibration signal data may include sensor data collected by the vibration sensor, the timestamp information of the time when the sensor data was collected, and the operating condition data of the vibration sensor when it was collecting sensor data.
[0047] Specifically, historical vibration signal data can be clustered and divided according to operating condition data and the sensor type of the vibration sensor to generate historical vibration signal data groups for each operating condition. It should be noted that each historical vibration signal data group corresponds to a different operating condition, and different historical vibration signal data groups for different operating conditions may correspond to a single vibration sensor.
[0048] S220. For the historical vibration signal data set under working conditions, generate a sequence of historical vibration signal values corresponding to different vibration sensors in the historical vibration signal data set under working conditions, according to the order of the acquisition timestamps.
[0049] S230. Perform linear correlation analysis on the numerical variation relationship in the historical vibration signal value sequence to determine the linear vibration relationship corresponding to the historical vibration signal value sequence.
[0050] Among them, linear vibration relationship can refer to the linear relationship between vibration signal value and acquisition timestamp information.
[0051] S240. Perform error range analysis on the linear vibration relationship and the sensor error range data corresponding to its vibration sensor to determine the vibration characteristic data corresponding to the vibration sensor.
[0052] Optionally, an error range analysis is performed on the linear vibration relationship and the sensor error range data corresponding to the vibration sensor to determine the vibration characteristic data corresponding to the vibration sensor. This includes: determining the standard vibration value corresponding to the linear vibration relationship at each acquisition time point based on the linear vibration relationship; and determining the maximum and minimum permissible vibration values corresponding to the vibration sensor at each acquisition time point based on the standard vibration value and the sensor error range data corresponding to the vibration sensor.
[0053] The standard vibration value can refer to the vibration signal value corresponding to the acquisition timestamp in a linear vibration relationship.
[0054] The sensor error range data can define the maximum downward deviation error threshold and the maximum upward deviation error threshold corresponding to the vibration sensor. It should be noted that the maximum permissible vibration value can be determined based on the standard vibration value and the maximum upward deviation error threshold, and the minimum permissible vibration value can be determined based on the standard vibration value and the maximum downward deviation error threshold.
[0055] In this embodiment of the invention, outside the range of the independent variable parameter (time stamp variable) in the linear vibration relationship, the standard vibration value is extended. The maximum and minimum permissible vibration values corresponding to the extended standard vibration value are the sums of the standard vibration value and the maximum upper deviation error threshold and the maximum lower deviation error threshold, respectively.
[0056] Optionally, after determining the maximum and minimum permissible vibration values of the vibration sensor at each acquisition timestamp, the method further includes: determining a maximum vibration linear relationship based on the linear vibration relationship and the maximum permissible vibration value; and determining a minimum vibration linear relationship based on the linear vibration relationship and the minimum permissible vibration value.
[0057] For example, the maximum and minimum linear vibration relationships can be determined by displacement based on the maximum and minimum permissible vibration values.
[0058] Optionally, the real-time vibration signal data can be corrected for errors based on the data error analysis results. This includes: if the real-time vibration signal data matches the vibration characteristic data corresponding to its respective vibration sensor, then the real-time vibration signal data is corrected for errors based on the linear vibration relationship corresponding to that vibration sensor. For example, the standard vibration value corresponding to the acquisition timestamp of the real-time vibration signal data in the new vibration relationship is used as the corrected result. If the real-time vibration signal data does not match the vibration characteristic data corresponding to its respective vibration sensor, it indicates that the vibration sensor needs to be replaced.
[0059] The technical solution of this invention divides historical vibration signal data according to working conditions, generates a collection sequence of historical vibration signal data according to the collection timestamp information, performs linear analysis on this collection sequence to determine the linear relationship of different collection sequences, and generates vibration characteristic data corresponding to the vibration sensor by combining the sensor error range data corresponding to the vibration sensor, thereby improving the accuracy of vibration characteristic data.

[0063] The real-time data analysis module 320 is used to collect real-time vibration signal data of the target sensor group and perform data error analysis on the real-time vibration signal data based on the vibration correlation characteristic data of the target sensor group.
[0064] The data correction module 330 is used to correct data errors in the real-time vibration signal data based on the data error analysis results.
[0065] The technical solution of this invention determines the vibration characteristic data of the target sensor group by performing correlation analysis on the historical vibration signal data of the target sensor group based on operating conditions. Then, based on the vibration correlation characteristic data, error analysis is performed on the real-time vibration signal data of the target sensor group, and error correction is performed on the real-time vibration signal data based on the error analysis results. This ensures the accuracy of the acquired data and avoids the impact on the analysis of the operating status of the monitoring equipment caused by the discontinuous vibration data acquisition due to the removal of equipment under unreasonable or inappropriate circumstances.
