模拟工艺流程仪表盘操作随着生产规模不断扩大，工艺生产过程对仪表自控的要求越来越高，检测控制点越来越多，基地式仪表和就地控制室操作方式满足不了比较复杂的工艺过程的要求。当时为观察工艺测量参数和便于实施现场操作，在仪表盘上增加模拟屏。模拟屏上人工绘制带检测点的主要工艺流程图，并安装运行和报警信号灯等来显示操作现状况，构成半模似流程操作盘。它可以直观形象地显示工艺流程和检测点，通过信号灯动态显示设备的运行和故障报警状态。也有在仪表盘上直接绘制主工艺流程，在检测点上开孔安装相应的仪表，显示当前设备的参数，构成全流程模拟操作盘。在20世纪60年代，这些带工艺流程的模拟屏均需向仪表盘制造厂特殊定制。20世纪90年代以来各高校和仪表盘制造厂先后研发推出了各种模拟屏系统，生产了一系列产品，如微电脑调度模拟屏、智能调度模拟屏、马赛克模拟工艺流程屏、污水处理屏、DLP大屏幕系统、LED电子显示屏系统等，广泛应用于石油化工厂、污水处理、煤矿选煤工艺、大型厂矿能源管理等领域。图14是污水水处理厂工艺流程模拟屏。
