摘要
针对应力波法锚杆锚固质量无损检测信号处理过程中存在的现场采集信号数目多,分析信号工作量较大的问题,提出利用Origin软件的批处理功能来对信号进行自动批量分析方法。设计了带有自适应数据分割功能的分析结果输出模板,解决了Origin软件对多组信号的批处理结果连续输出、难以区分的问题,同时结合具体实例介绍了实现信号批量分析的操作步骤。结果表明该方法操作简单,不需要编制程序,易于掌握,而且发现在此基础上结合Origin强大的数据分析功能可以开发出基于其它分析方法的信号批量分析模板。
In order to solve the problems of heavy workload of signal analysis because of the large number of signals collected on site during the signal processing of nondestructive testing of stress wave in bolt anchoring quality,we propose a method that,based on the batch processing function of Origin software,can automatically analyze signals in aggregate. We designed the analysis results output template having the function of adaptive data partitioning,which solved the problems of Origin software that the outputs of batch processing results of many group signals were written to the file continuously and were difficult to distinguish. With a real case,we exemplified the operation procedures of batch signal analysis. It turned out that this method is easy to use without programming. It was also found that with this method,and with the powerful data analysis function of Origin,a batch signal analysis template which is based on other signal analysis methods can be developed.
