Problems solved by technology

However, due to the large changes in the outdoor monitoring environment, the complex format of monitoring information, and the large amount of information, if these data cannot be effectively predicted and processed in a timely manner, many abnormal data will not be effectively identified, and missing information will reduce the effectiveness of sensor system monitoring. , and the analysis of monitoring data must be based on accurate and effective monitoring data. Wrong or abnormal monitoring data will reduce the results of numerical analysis, thereby affecting the function and characteristic analysis of the system, and bringing great errors to subsequent data processing. , normal information cannot be effectively utilized

Embodiment 2

[0084] Embodiment 2 includes all structures and method parts of Embodiment 1, and also includes the following modification steps between steps 300 and 400 of Embodiment 1:

[0085] The computer selects 20,000 sampling values ​​with a time interval of Δt from the average detection signal, and each sampling value is arranged in chronological order to form the detection signal I(t);

[0086] For each sample value ES(t) except the first sample value and the last sample value in I(t) 1 ), using the formula Calculate the smooth coefficient ratio;

[0087] The computer presets weight thresholds 0.5, 1, and 1.65 that increase sequentially;

[0088] For the sampling value whose ratio is in the range of [1-A1, 1+A1], correct the sampling value to B1 ES(t 1 ), A1 is 0.3, B1 is 0.35;

[0089] For the sampled value whose ratio is in the range of (0.6, 1-A1) or (1+A1, 1.65), correct the sampled value to B2ES(t 1 ), B2 is 0.54;

[0090] The corrected sampling values ​​are used to repl...
