The optical fiber vibration sensor is set as the target sensor, and the working condition evaluation information of the target sensor within the time threshold is obtained. The working condition evaluation information includes the sensitivity evaluation coefficient and the stability evaluation coefficient.

The infrared characteristic image of the target sensor in the sub-time period is obtained, and the area corresponding to the temperature value exceeding the preset temperature value threshold is obtained from the infrared characteristic image, and it is set as the red temperature area. Then, the area corresponding to the same area of the red temperature area in each sub-time period is obtained, and it is set as the stability evaluation coefficient. It should be noted that the stability evaluation coefficient is an influencing parameter that reflects 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.

The difference value between the signal attenuation characteristic curve and the standard signal attenuation characteristic curve is set as a 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.

[0058] If the shutdown characteristic performance coefficient is less than the preset shutdown characteristic performance coefficient threshold, a shutdown stability signal is generated;
[0059] If the shutdown characteristic performance coefficient is greater than or equal to the preset shutdown characteristic performance coefficient threshold, a shutdown risk signal is generated, and the shutdown stability signal or shutdown risk signal is sent to the management response unit. After receiving the shutdown stability signal or shutdown risk signal, the management response unit immediately performs the preset warning operation corresponding to the shutdown stability signal or shutdown risk signal, so as to carry out reasonable and targeted management of the target sensor to improve the stability of the target sensor's operating performance.

The specific process of obtaining and analyzing the actual interference evaluation coefficient is as follows:
[0062] The operation interference information of the working area where the target sensor is located within the time threshold is obtained, and the operation interference information includes an interference characteristic coefficient and a physical interference index.
[0063] In an embodiment of the present invention, the interference characteristic coefficient represents the product of the maximum value of the frequency corresponding to the preset threshold value when the corresponding value of the environmental interference information in the working area of the target sensor exceeds the preset threshold value and the superposition time after data normalization processing. The environmental interference information includes temperature, humidity, electromagnetic interference, etc. The superposition time represents the sum of the overlapping time values corresponding to the environmental interference information exceeding the preset threshold value. 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.
[0064] In an embodiment of the present invention, the physical interference index indicates the number of interference sources in the working area of the target sensor where the minimum straight-line distance between the target sensor and the interference source is less than a preset threshold. The interference sources include inverter power supply equipment, frequency converter, etc. It should be noted that the operating performance risk of the target sensor is analyzed from the perspective of physical interference to improve the accuracy of the analysis results.

That is, it analyzes the impact of historical factors on current operation performance from a comprehensive perspective to provide data support for subsequent analysis. The specific historical obstruction operation classification analysis process is as follows:
[0067] The risk interference information of the target sensor within the time threshold is obtained, and the risk interference information includes parameter offset value and working condition performance value.
[0068] In an embodiment of the present invention, the parameter offset value indicates the duration of time during which the corresponding value of the operating parameter of the target sensor exceeds the preset threshold value during the historical operation process. The operating parameters include operating voltage, operating power, etc. It should be noted that the larger the value of the parameter offset value, the deeper the damage caused by the legacy problem of the target sensor.
[0069] In an embodiment of the present invention, the proportion of the number of times the startup response time exceeds a preset startup response time threshold in the total number of historical startup times of the target sensor is obtained, and the product obtained by multiplying the proportion by the number of historical output delays of the target sensor after data normalization is set as the operating condition performance value. It should be noted that the operating risk of the target sensor is understood from the perspective of historical operating performance. The larger the numerical value of the operating condition performance value, the greater the risk of abnormal operating performance of the target sensor.
[0070] The parameter offset value and the working condition performance value are labeled CP and GB respectively. Substitute the parameter offset value CP and the working condition performance value GB into the formula The historical evaluation coefficient is obtained, where a1 and a2 are the preset weight factor coefficients of the parameter offset value and the operating condition performance value, respectively, and a3 is the preset error correction factor coefficient. a1, a2, and a3 are all greater than zero. It should be noted that a comprehensive evaluation of historical impacts is performed from the perspective of data fusion in order to analyze the impact of historical factors on current operating performance from a comprehensive perspective.
[0071] Perform discriminant analysis on the actual interference evaluation coefficient and the historical evaluation coefficient:
[0072] If the actual interference evaluation coefficient = 0, and the historical evaluation coefficient is less than the preset historical evaluation coefficient threshold, it is determined to be regular interference;
[0073] If the actual interference evaluation coefficient = 0 is not satisfied, and the historical evaluation coefficient is less than the preset historical evaluation coefficient threshold, it is judged as high-level interference, where the interference impacts corresponding to conventional interference and high-level interference increase in turn, and the preset operating interference factors Gm corresponding to conventional interference and high-level interference are obtained, m∈{1, 2}, that is, when m=1, the preset operating interference factor G1 represents conventional interference, and when m=2, the preset operating interference factor G2 represents high-level interference, 0<G1<G2, and the preset operating interference factor Gm is sent to the performance monitoring center.
[0074] In summary, the present invention performs performance monitoring and analysis from the two perspectives of operation and shutdown of the target sensor, that is, the target sensor operation performance is analyzed through multi-angle analysis, which helps to improve the credibility of the analysis results. At the same time, it combines physical interference, non-physical interference and historical comprehensive interference for fusion evaluation and analysis, which helps to increase the comprehensiveness of data analysis in the process of target sensor operation performance analysis, and then intuitively understand the operation performance of the target sensor based on the output results. The operation performance evaluation coefficient is obtained and analyzed from the operation perspective of the target sensor to determine whether the target sensor operation performance is normal, so as to perform reasonable and targeted management of the target sensor, so as to improve the operation safety of the target sensor and improve the stability of the target sensor operation performance. Based on the information progressive method, the shutdown performance evaluation feedback analysis is further performed from the shutdown perspective of the target sensor to understand whether the shutdown performance of the target sensor is normal, so as to intuitively feedback the target sensor operation performance monitoring results based on the output results, which helps to manage and adjust the target sensor and improve the monitoring and management efficiency of the target sensor.
[0075] The threshold is set to facilitate comparison. The size of the threshold depends on the amount of sample data and the number of bases set by technicians in this field for each set of sample data; as long as it does not affect the proportional relationship between the parameter and the quantized value.
[0076] The size of the coefficient is to quantify each parameter to obtain a specific numerical value, which is convenient for subsequent comparison. The size of the coefficient depends on the amount of sample data and the preliminary setting of the corresponding operating coefficient for each set of sample data by technical personnel in this field; as long as it does not affect the proportional relationship between the parameter and the quantized value.
[0077] The above formulas are obtained by collecting a large amount of data and performing software simulation, and a formula close to the actual value is selected. The coefficients in the formula are set by those skilled in the art according to actual conditions. The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes based on the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
