固定式海洋平台立柱腐蚀超声检测系统

摘要

海洋平台在海浪、海风、海流及潮汐等恶劣环境的共同作用下,平台立柱部位最容易出现腐蚀,影响平台的安全性能.为了检测平台腐蚀情况,设计了一套超声波检测系统,给出了系统的结构组成、电路组成、电路模块组成.介绍了系统底层软件总流程,并进行了室内模拟检测.结果表明,检测系统可以完成数据的采集和压缩,采用的计零压缩算法对超声信号具有较高的压缩效率.%Offshore platforms are always working under complex and extremely adverse circumstance, such as sea wave,sea wind,ocean current and tide. The pillars are prone to be corrupted, affecting the security of the platform. A set of ultrasonic inspection system was designed to detect the corrosion of the pillar. The key design proposal for the circuit system and mechanical structure has been interpreted. The experiment has improved that the system could fulfill the data acquisition and compression successfully and the data compression algorithm based on zero-counting has a high compression ratio at ultrasonic signal.
