海底管道微小泄漏球形内检测器整体设计

Overall Design of Spherical Inner Detector for Tiny Leakage of Subsea Pipeline

针对海底管道微小泄漏检测,提出管道球形内检测器整体设计方案。文章从整体平台方案、硬件电路设计以及下位机软件设计三方面介绍了球形内检测器的整体结构。整体平台方案阐述了各模块的作用及相互之间的关联。硬件电路设计包括处理器的选取、存储模块的选取与设计和电源模块管理等;方案最终选用Samsung公司基于ARM1176架构的S3C6410处理器,速度等级为Class10的TF卡,采用10节电池总容量为31Ah组成的电池组。软件设计包括驱动程序及应用程序的设计,其中后者采用了高效的多线程编程方式。

For detecting tiny leakage of subsea pipeline, the overall design of the spherical inner detector is proposed, which includes three aspects： the overall platform solution, the hardware circuit design and the software design of lower computer. The overall solution illustrates the role of each module and their connections. The hardware design includes selection of the processor and storage module, the management of the power supply module, etc.; the S3C6410 processor based on ARM 1176 architecture produced by Samsung Co., the TF card with a speed of Class 10 and the battery pack containing ten 3 100 mAh lithium batteries are chosen. The software design includes drive program and application program, the latter uses effective multi-threaded programming.
