摘　　要：介绍了一种基于小波变换的数据压缩/解压系统.该系统对信号首先按不同的频带进行分解,然后分别进行数据压缩和数据重构.通过应用于远程实验的多功能转子试验台的振动信号数据压缩为实例,验证了该系统具有较好的压缩效率、压缩速率和可靠性.A data compressing/decompressing system based on wavelet transform is presented in this paper. In this system , the signal is decomposed on different frequency bands, then data compression and data recomposition are performed respectively. Experimental results show that the compress efficiency, the compression velocity and the reliability are much higher through an example of vibration signal compression in area of multifunctional synthetic test-rig in remote experiment.
