摘　　要：针对输油管道微小泄漏检测的特殊需求,以一种球形内检测器为载体,设计并实现了一套多传感器数据同步采集与存储系统,采用嵌入式ARM-Linux的方案。详细论述了该系统的整体结构、工作原理、硬件组成、软件设计等,并实验验证了该系统能准确地采集并保存所需要的信号,为后续准确识别和精确定位微小泄漏提供可靠的原始数据支持。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.
