深水导管架多通道腐蚀监测数据采集系统开发与应用

Development and Application of Multichannel Data Acquisition System for Corrosion Monitoring of Deep Sea Jacket

利用阴极保护监测系统对阴极保护电位和电流进行监测是评估海洋构筑物阴极保护系统工作状态的有效技术手段。为了对各关注部位的阴极保护状态实施实时和同步测量，设计并采用了基于PCI总线结构的多通道信号采集方案，开发了相应的数据采集应用程序，构建多通道腐蚀数据采集系统并投入现场应用，取得了良好的效果。

Monitoring cathodic protection （CP） potentials and currents with CP monitoring system is one of the effective means to evaluate the CP system. To conduct a real-time and synchronized measurement of CP status at each of most concerned positions on offshore structure, a multichannel data acquisition system based on PCI bus architecture is designed and application program is developed. The multichannel Data Acquisition System for Corrosion Monitoring has been built and got a good application.
