【摘要】 针对来自于腐蚀监测中的数据,石油企业提出了这样的需求:设计一套图形软件,目的是呈现和分析监测数据,提高工作效率,节约生产成本。论文采取C#作为开发工具,详细说明了软件的设计原理和设计过程。腐蚀监测被认为是实现现代工业文明生产的重要手段。腐蚀监测技术是由实验室腐蚀试验方法和设备的无损检测技术发展而来的,其目的在于揭示腐蚀过程以及了解腐蚀控制的应用情况和控制效果。现代的腐蚀监测实践经验大部分来自化学、石油化学、炼油、动力等工业。电化学测试方法是一种比较好的无损检测方法。当0.1μA/cm~2的自然腐蚀电流流经1小时而生成的锈蚀产物约为1.04至104mg/cm~2。如果用以前的失重法,即使不考虑除锈技术上的困难,测量出这样小的重量变化也很困难。而用电化学方法却很容易,它的主要优点是,能够快速响应,所得信息常常能与实验室中的背景研究直接联系,更有可能利用探测器来判断生产装置的腐蚀行为,增加了诊断的可靠性,有助于选择补救措施或控制系统。常用的电化学方法主要有:电阻法(ER),电化学噪声技术(ECN),交流阻抗技术(EIS),线形极化法(LPR)和恒电量技术。通常腐蚀监测检测到的原始数据是一些时间/数字对组成的一系列表格数据。这些时间/数字对表示在某个时间点,探测到的各种腐蚀参数。这些参数一般情况下都非常多,少则几百行,多则上万行。直接看这些数据既不直观,也不便于统计。本论文的研究主题就是通过编写程序,实现利用计算机软件进行腐蚀数据的图形显示和统计,其优点有两个方面:一方面用图形的方式将测控数据直观显示到屏幕上,实现即时打印;另一方面,统计用户需要的腐蚀速率等数据,为软件用户提供精确的监测分析结果。更多还原

【Abstract】 From the data of corrosion monitoring, Oil companies need to design a set of graphics software, the purpose is to present and analyze the monitoring data, to improve working efficiency, saving the cost of production. By using C# as a development tool, this dissertation describes software design principles and design process.Corrosion monitoring is considered to be an important modern industrial civilization. Corrosion monitoring technology was developed by laboratory corrosion test methods and equipment developed from the non-destructive testing technology, which aims to reveal the corrosion process and to understand the application of corrosion control.The corrosion monitoring practices of modern mostly come from chemical, petrochemical, oil refining and so on. Electrochemical method is a good non-destructive testing method. When 0.1μA/cm2 the nature corrosion current flows through the corrosion product which 1 hour produces approximately is 1.04 to 104mg/cm2 .If the previous weight loss, even without considering the technical difficulties rust, measure the weight of such a small change is also very difficult. The electrochemical method is very easy, its main advantage is the ability to respond quickly, information is often obtained with the background of the laboratory directly, which is more likely to use the detector to determine the corrosion behavior of production units, to increase the reliability of diagnosis, to select remedial measures or control systems.The methods like resistance method (ER), electrochemical noise technique (ECN), AC impedance (EIS), linear polarization method (LPR) and the constant power technology are usually used to corrosion monitoring.Corrosion monitoring is usually detected by the raw data is some time/digital data on the composition of a series of tables. The time/number showed that at some point in time to detect the various corrosion parameters. These parameters are under normal circumstances, ranging from a few hundred lines, as many thousands of lines. With the view to these data which is neither intuitive nor easy to statistics. Theme of this research is to through the preparation process to achieve the corrosion data, computer software, graphics and statistics, the advantage has two aspects. On the one hand we can control a graphical way to visualize the measured data on the screen for instant printing; On the other hand, users use the corrosion rate of statistics and other data to accurate monitoring results.更多还原
