从信号和信号处理知识入手，介绍了通过使用VISUAL DESIGNERTM软件对由数据采集仪UDAS－1001E－2采集而来的数据进行处理，从而实现非接触式转速的测量，验证了利用互相关原理进行非接触式速度测量的可能性。将所搭建的实验台移植并应用于测定深埋在地下的输液(气)管的裂损位置进行了研究，以避免全线开挖，节省了巨大的工作量，值得普遍推广应用。

This thesis begins with the knowledge on the signal and the signal processing and introduces how to process the data col￣lected from the UDAS by use of the VISUAL DESIGNERTM,thus achieving the non￣contact velocity measurement. It verifies the pos￣sibility that the non￣contact velocity measurement can be realized using the cross￣correlation theory. It also sets up an experiment platform which can be used to transplant of the conveying fluid( gas) pipes deeply buried underground and applied to the study of its crak place,so that mass digging can be avoided and heavy work can be saved by using this method, so it is worth to be promoted and used widely.
