Design and Implementation of Corrosion Information Comprehensive Analysis System for Refining Device

某石化公司目前的炼化装置腐蚀信息管理系统存在功能不足、扩展性不强、数据集成度不高等问题。通过对该公司的腐蚀信息管理进行深入的需求分析,以数据流图技术进行系统数据分析,以E-R模型进行系统数据结构设计,以模块化技术进行系统功能设计,以灰色理论技术建立腐蚀预测模型。设计完成后以Java EE、AJAX等开发技术实现了一个新的炼化装置设备腐蚀信息综合分析系统。系统对不同装置设备的腐蚀数据建立了统一的数据结构和程序接口,具有可扩展性强、数据整合量大、数据智能分析等特点。实际应用结果表明,系统可以直接获取各种常用的腐蚀数据及报表,自动对腐蚀趋势进行分析与预测,为科学制定检修计划提供依据,大大提高该公司的腐蚀管理工作的效率和水平。

A petrochemical company＇ s corrosion management system has some problems, such as insufficiency of tunction, low expansi- bility,low data integration and so on. A requirement of this company＇ s corrosion management was analyzed deeply. new corrosion in- formation comprehensive analysis system for refining device was designed and implemented. The system＇s data was analyzed by data flow diagram. The system＇ s data structure was designed by E-R model. The system＇ s functions were designed by modeing. The corro- sion predicted model was established by gray theory. The system was implemented by some software techniques like Java E2 and AJAX. The unified data structure and program interface for different refining devices were created. The system has strong expansibilio ,high data integration and intelligent analysis. The system＇ s application results show that a variety of commonly used corrosion data and r^orts can be obtained directly, and corrosion trend is analyzed automatically so that it can provide the scientific basis for the maintenance pan. The system can greatly improve the efficiency and quality of the company＇ s corrosion management.
