面向对象程序设计在湿蒸汽发生器集中监测中的应用

Application of Object-oriented Programming Method in Central Monitoring System for Wet Steam Generators

湿蒸汽发生器是油田三次采油的重要设备．为了使其安全、可靠运行并产生高质量的高温、高压蒸汽，必须对其运行过程的温度、压力及报警信号等有关参量进行集中监测，传统的解决方法是人工定时现场抄表，这不仅工作量大，而且极不安全．本文简要地介绍了一种计算机集中监测系统的组成及功能，并着重介绍目前比较流行的面向对象的程序设计方法（Objec－OrientedProgramming）．通过实例从应用的角度描述了Vi－sualC++语言在Windows95环境下的编程特点．软件设计既满足了湿蒸汽发生器集中监测系统的实时性的要求，又使系统具有快速、便捷的人-机交互功能．

The wet steam generator is an important equipment for third oil-extration. In order to fulfill the demands of safety and reliability, it is very necessary to monitor process variable, such as temperature, pressure and alarm signals. The traditional method is that worker must gn to the field and get data through manual acting. This paper presents a central monitor computer-based system, its architecture and function, and inteduces specially the popu-lar Object-Oriented Programming (OOP) method. Taking the central menitoring system for wet steam generators as an examle, this paper details the use of Visual C + + for Windows 95. Moreover, the software design meets the needs of Real-Time, and the system has a rapid and convenient Man-Machine interface as well.
