Study of the data compressing method based on wavelet

In order to realize real-time detection of pipeline defects, developed a set of ultrasonic detection system, System is mainly to complete the pipeline corrosion data collection, processing and storage, so it will generate a large number of ultrasound data, and take up storage space, In order to reduce the amount of data storage, in this paper, a method based on wavelet transform to achieve compression defect information, for active-duty maintenance and replacement of piping systems have some theoretical guidance to the meaning, while the remaining life of pipelines laid the foundation for the study.
