摘　　要：针对跌落试验机计算辅助测试系统结构的现状,提出了改进思路。重点分析了数据的处理方式,充分考虑到采集数据的特性,采用数字滤波方式,实现更加完善准确的测量。详细介绍了双线性变换法在IIR中的使用,结合巴特沃夫和契比雪夫滤波器,给出了软件滤波的实现过程。The frame of the compute aid testing system for transport packing was described. Thoughts on how to rebuild it were put forward. The method to process the original data was analyzed. By adopting the method of digital filter with the consideration of the property of data gathering, a more perfect and accurate measurement was achieved. In this method, detailed instructions on how bi- linearity transforming was used in IIR and the flow to realize the process were also introduced.
