摘　　要：外加电流阴极保护(ICCP)技术是有效的舰船、桥梁防腐方法。本文主要介绍舰船阴极保护实时监测系统的设计,主要涉及人机接口和数据存储两方面。人机界面部分通过迪文彩色触摸屏和阴极保护系统测控板ARM芯片LCP2138串口相接,通过Modbus远程终端协议实现阴极保护系统与arm处理器的通信,实现基于串口触摸屏的实时在线监测。实时数据基于LPC2138与RS485通信接口存储在实时数据库中,可通过触摸屏实时显示,也可存储在外部SD卡或U盘中。初步测试结果表明,该系统实现了阴极保护系统的远程控制监测。设计方案总体合理,运行可靠。Impressed current cathodic protection( ICCP) technology is commonly used for protecting ships and bridges from corroding.In this design,a central monitoring and controlling unit is designed for multi-ship mounted ICCP equipments,where Modbus remote terminal protocol is utilized to realize communication between ICCP system and the arm processor LCP2138,and a serial touch screen is utilized for online monitoring and controlling. A real-time database is also built for data storage and offline analysis. The result shows that the remote monitor of the ICCP systems has been established and validated.
