英文摘要：

In consideration of the special needs for detection of tiny leakage on oil pipelines, a multi-sensor data acquisition and storage system is designed and implemented, with a spherical inner detector as its carrier. This system adopts an embedded ARM-Linux scheme. A detailed description of general principle,hardware components, software design and other elements of the system is represented. The experiment shows that the system can well capture and store signals detected,while it also supports the follow up tiny leakage identifying and locating with reliable raw data.
