研究了一种Windows环境下的联合站油水分离过程集成的人机界面 监控与数据采集系统 ,包括流程显示、参数监测、历史趋势、报警记录、参数修改、数字滤波、数据采集等模块 ,能够收集、查阅、存储、控制和管理控制过程的各种基本信息 .结合工业控制的特点 ,提出了“自治函数”和“响应函数”的概念 ,应用在几十个工控过程中 ,从根本上解决了弱时间条件下的定时数据采集对多任务的依赖 .控制系统投运后 ,联合站沉降脱水压力和电脱水压力稳定在 0 .2 5～ 0 .35MPa之间 ,外输油含水控制在 0 .15%～ 0 .2 0 % .可满足现场需要
A man-machine interface monitoring and data acquisition system integrating oil-water separation process in the integrated station under Windows environment is studied, including flow display, parameter monitoring, historical trend, alarm record, parameter modification, digital filtering and data acquisition. , To access, store, control and manage all kinds of basic information of the control process.Combined with the characteristics of industrial control, the concepts of “autonomous function” and “response function” are put forward, which are applied in dozens of industrial control processes and fundamentally solve When the control system is put into operation, the settlement dewatering pressure and dewatering pressure of the united station are stabilized at 0. 25 ~ 0. 35MPa, and the water content of the external oil is controlled at 0. 15% ~ 0 .2 0%. To meet the needs of the scene
