Problems solved by technology
[0002] When collecting the data of the structural health monitoring system, three kinds of results will be obtained: good data, missing data and abnormal data; when evaluating the structural health monitoring system at present, the target is the good data, the data to be collected After screening, the data sets after missing data and abnormal data are kicked out; however, the evaluation of structural safety performance is only based on good data, ignoring the imbalance in the proportion of good data, missing data and abnormal data. problems, that is, whether the data collection process is abnormal and the quality of the collected data is poor, so it is not possible to obtain comprehensive and accurate evaluation results

The invention discloses a structure health monitoring system. The structure health monitoring system comprises a sensor system, a data collection and transmission system, a data control system and an evaluation system. The data collection and transmission system is connected with the sensor system and used for picking signals collected by the sensor system. The data collection and transmission system is connected with the data control system and used for transmitting the picked signals to the data control system to be processed. The evaluation system is connected with the data control system, uses the perfectness ratio as an evaluation index and is used for evaluating the processed result of the data control system. By the adoption of the perfectness ratio index, the working state of the structure health monitoring system is evaluated, the defect that good and bad quality of the data collected by a structure health monitoring system in the prior art is ignored is overcome, and the working condition of the structure health monitoring system can be evaluated more accurately and comprehensively.
Description
Technical field [0001] The invention relates to the field of structural health monitoring, in particular to a structural health monitoring system and an evaluation method thereof. technical background [0002] When collecting data from the structural health monitoring system, three results will be obtained: good data, missing data, and abnormal data; currently, when evaluating the structural health monitoring system, the target is good data, the data to be collected After screening, the data set with missing data and abnormal data is eliminated; however, only evaluating the structural safety performance based on good data ignores the imbalance between good data, missing data and abnormal data. The problem of whether the data collection process is abnormal and the quality of the collected data is poor, so a comprehensive and accurate evaluation result cannot be obtained. [0003] In view of the aforementioned shortcomings in the evaluation of the existing structural health monitori...
