Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1: Please refer to Figures 1 to 2 As shown, the present invention is an operation performance monitoring system for an optical fiber vibration sensor based on artificial intelligence, including a performance monitoring center, a database, an operation performance analysis unit, a shutdown monitoring unit, an operation hindrance unit, a historical factor analysis unit, and a management response unit.

The specific process of obtaining and analyzing the operation performance evaluation coefficient is as follows: Collect the operation period of the optical fiber vibration sensor and set it as the time threshold. Set the optical fiber vibration sensor as the target sensor, and obtain the working condition evaluation information of the target sensor within the time threshold. The working condition evaluation information includes a sensitivity evaluation coefficient and a stability evaluation coefficient.

[0034] In the embodiment of the present invention, the analysis process of the stability evaluation coefficient is as follows: Divide the time threshold into \(i\) sub - time periods, where \(i\) is a natural number greater than zero. Obtain the infrared feature image of the target sensor within the sub - time period. From the infrared feature image, obtain the area corresponding to the region where the temperature value exceeds the preset temperature value threshold, and set it as the red - temperature region. Then, obtain the area of the same region corresponding to the red - temperature region within each sub - time period, and set it as the stability evaluation coefficient. It should be noted that the stability evaluation coefficient is an influencing parameter reflecting the actual operating performance of the target sensor. The larger the value of the stability evaluation coefficient, the greater the risk of abnormal operating performance of the target sensor.

[0037] The shutdown monitoring unit is used to perform a shutdown performance evaluation feedback analysis on the received shutdown information, so as to analyze the performance risk situation of the target sensor from the perspective of shutdown, and improve the stability of the operating performance of the target sensor.

The shutdown information includes the shutdown performance value and the characteristic defect index; In the embodiment of the present invention, the analysis process of the shutdown performance value is as follows: Obtain the duration between the shutdown moment of the target sensor and the moment when the signal decays to zero within the analysis duration, and set it as the shutdown performance value. It should be noted that the larger the value of the shutdown performance value, the greater the failure risk of the target sensor.

[0038] In the embodiment of the present invention, obtain the signal attenuation characteristic curve of the target sensor within the analysis duration, and at the same time obtain the standard signal attenuation characteristic curve of the target sensor. Obtain the difference value between the signal attenuation characteristic curve and the standard signal attenuation characteristic curve, and set the difference value between the signal attenuation characteristic curve and the standard signal attenuation characteristic curve as the characteristic defect index. It should be noted that the larger the value of the characteristic defect index, the greater the failure risk of the target sensor.

[0039] Set the value obtained by multiplying the corresponding values of the shutdown performance value, the characteristic defect index, and the preset operation interference factor Gm of the current target sensor as the shutdown characteristic performance coefficient, and perform discrimination processing on the shutdown characteristic performance coefficient: If the shutdown characteristic performance coefficient is less than the preset shutdown characteristic performance coefficient threshold, generate a shutdown stable signal; If the shutdown characteristic performance coefficient is greater than or equal to the preset shutdown characteristic performance coefficient threshold, generate a shutdown risk signal, and send the shutdown stable signal or the shutdown risk signal to the management response unit. After receiving the shutdown stable signal or the shutdown risk signal, the management response unit immediately performs the preset warning operation corresponding to the shutdown stable signal or the shutdown risk signal, so as to perform reasonable and targeted management on the target sensor to improve the stability of the operation performance of the target sensor.

[0040] Embodiment 2: The operation hindrance unit is used to retrieve the operation interference information of the target sensor from the database, and at the same time perform analysis on obtaining the on-site interference evaluation coefficient for the operation interference information, so as to perform analysis from two perspectives of physical interference and non-physical interference, in order to understand the comprehensive operation interference degree of physical interference and non-physical on the target sensor. The specific process of obtaining and analyzing the on-site interference evaluation coefficient is as follows: Obtain the operation interference information of the working area where the target sensor is located within the time threshold, and the operation interference information includes the interference characteristic coefficient and the physical interference index.

[0041] In the embodiments of the present invention, the interference characteristic coefficient represents the product value obtained by multiplying the maximum value in the frequency corresponding to the environmental interference information value exceeding the preset threshold in the working area where the target sensor is located and the superposition duration after data normalization processing. The environmental interference information includes temperature, humidity, electromagnetic interference, etc. The superposition duration represents the total sum of the coincidence durations corresponding to the environmental interference information values exceeding the preset threshold. It should be noted that the larger the value of the interference characteristic coefficient, the greater the risk of abnormal operation of the target sensor.

[0042] In the embodiments of the present invention, the physical interference index represents the number of interference sources in the working area where the target sensor is located whose minimum straight-line distance from the target sensor is less than the preset threshold. The interference sources include inverter power supply equipment, frequency converters, etc. It should be noted that from the perspective of physical interference, the operating performance risk of the target sensor is analyzed to improve the accuracy of the analysis results. The larger the value of the physical interference index, the greater the operating performance risk of the target sensor.

[0043] The interference characteristic coefficient and the physical interference index are compared and analyzed with the preset interference characteristic coefficient threshold and the preset physical interference index threshold. The number of the interference characteristic coefficient and the physical interference index that are greater than or equal to the preset interference characteristic coefficient threshold and the preset physical interference index threshold is set as the live interference evaluation coefficient. It should be noted that the live interference evaluation coefficient is an influence parameter reflecting the operating performance of the target sensor.

[0044] The historical factor analysis unit is used to collect the risk interference information of the target sensor and simultaneously conduct a historical obstacle operation division analysis on the risk interference information, that is, analyze the influence of historical factors on the current operating performance from a comprehensive perspective to provide data support for subsequent analysis. The specific historical obstacle operation division analysis process is as follows: Obtain the risk interference information of the target sensor within the time threshold. The risk interference information includes the parameter deviation value and the working condition performance value.

[0045] In the embodiments of the present invention, the parameter deviation value represents the duration corresponding to the operating parameter value exceeding the preset threshold during the historical operation of the target sensor. The operating parameters include operating voltage, operating power, etc. It should be noted that the larger the value of the parameter deviation value, the deeper the damage degree caused by the remaining problems of the target sensor.

[0046] In the embodiments of the present invention, obtain the ratio of the number of times the startup response duration exceeds the preset startup response duration threshold in the total number of historical startups of the target sensor, and set the product value obtained by multiplying the ratio value by the historical output delay times of the target sensor after data normalization processing as the working condition performance value. It should be noted that from the perspective of historical operation performance, understand the operating risk situation of the target sensor. The larger the value of the working condition performance value, the greater the risk of abnormal operation performance of the target sensor.

[0047] Label the parameter offset value and the operating condition performance value as CP and GB respectively, and substitute the parameter offset value CP and the operating condition performance value GB into the formula to obtain the historical evaluation coefficient, where a1 and a2 are the preset weight factor coefficients of the parameter offset value and the operating condition performance value respectively, a3 is the preset error correction factor coefficient, and a1, a2, and a3 are all greater than zero. It should be noted that the historical influence is comprehensively evaluated from the perspective of data fusion to analyze the influence of historical factors on the current operating performance from a comprehensive perspective.

[0048] Conduct discriminant analysis on the live interference evaluation coefficient and the historical evaluation coefficient: If the live interference evaluation coefficient = 0 and the historical evaluation coefficient is less than the preset historical evaluation coefficient threshold, it is judged as a normal interference; If the live interference evaluation coefficient ≠ 0 and the historical evaluation coefficient is less than the preset historical evaluation coefficient threshold, it is judged as a high-level interference. Among them, the interference effects corresponding to normal interference and high-level interference increase in sequence. Obtain the preset operating interference factor Gm corresponding to normal interference and high-level interference, m ∈ {1, 2}, that is, when m = 1, the preset operating interference factor G1 represents normal interference, and when m = 2, the preset operating interference factor G2 represents high-level interference, 0 < G1 < G2. Send the preset operating interference factor Gm to the performance monitoring center.

[0049] In summary, the present invention conducts performance monitoring and analysis from the two perspectives of the operation and shutdown of the target sensor, that is, analyzes the operating performance of the target sensor through multi-angle analysis, which helps to improve the credibility of the analysis results. At the same time, combining physical interference, non-physical interference, and historical comprehensive interference for fusion evaluation and analysis helps to increase the comprehensiveness of data analysis during the analysis of the operating performance of the target sensor, and then intuitively understand the operating performance of the target sensor based on the output results. Obtain and analyze the operating performance evaluation coefficient from the operating perspective of the target sensor to judge whether the operating performance of the target sensor is normal, so as to manage the target sensor reasonably and pertinently to improve the operating safety of the target sensor and at the same time improve the stability of the operating performance of the target sensor. And further conduct shutdown performance evaluation and feedback analysis from the shutdown perspective of the target sensor based on the information progression method to understand whether the shutdown performance of the target sensor is normal, so as to intuitively feedback the operating performance monitoring results of the target sensor based on the output result situation, which helps to manage and adjust the target sensor and improve the monitoring and management efficiency of the target sensor.

[0050] The setting of the threshold value is for the convenience of comparison. Regarding the size of the threshold value, it depends on the amount of sample data and the base quantity set by those skilled in the art for each group of sample data; as long as it does not affect the proportional relationship between the parameter and the quantified value.

[0051] The size of the coefficient is a specific value obtained by quantifying each parameter for subsequent comparison. Regarding the size of the coefficient, it depends on the amount of sample data and the corresponding operation coefficient initially set by those skilled in the art for each group of sample data; as long as it does not affect the proportional relationship between the parameter and the quantified value.

[0052] The above formulas are all obtained by collecting a large amount of data for software simulation and selecting a formula close to the true value. The coefficients in the formulas are set by those skilled in the art according to the actual situation. As mentioned above, this is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, making equivalent substitutions or changes according to the technical solution and inventive concept of the present invention, shall be covered by the protection scope of the present invention.
