海底油气管道检测数据采集系统研究

Study on the detecting data acquisition system for seabed oil & gas pipe-line

提出压力差驱动爬行器携带漏磁传感器、超声波传感器、里程轮和磁力角传感器对海底油气管道状况及损伤位置数据进行采集的系统方案,采用漏磁和超声波两种信息融合技术,可以确保检测的准确程度。里程计数器和磁力角传感器记录数据可以给出损伤点的位置,对指导现场修复意义重大,并采用ARM嵌入式处理器完成数据的预处理和降噪与压缩存储,运算速度高,功耗低,可以实现远距离海底油气管道的状况检测。

A kind of data acquisition method is presented in this paper, it uses a robot driven by pressure difference with magnetic flux leakage sensor, ultrasonic sensor, mileage wheel and magnetic force angle sensor, it can collect the data of the seabed oil & gas pipe-line state and the location of defeat point. This system has more high detecting precision by using the information fuse technology of magnetic flux leakage and ultrasonic, and can give the accuracy location of defect point in seabed oil & gas pipe-line by using mileage wheel and magnetic angle sensor. ARM embed processor is used to collect data, pretreatment data, noise reduction, compress and store information, so its operation speed is high, and ist power dissipation is lower, and can inspect longer distance seabed oil & gas pipe-line.
