电厂管控一体化

       在厂网分开、竞价上网的形势下，火力发电厂的信息化受到特别的重视。由于电力系统在国内计算机信息管理系统应用方面，实施较早，加之与其它流程工业相比有特殊性，所以目前电厂信息系统架构如图3所示。

      目前MIS负责检修、燃料、财务、物资、设备、竞价上网管理等；SIS负责运行监视、设备状态检测、运行评估、操作指导、负荷分配等，这些功能满足了管控一体化的一般需要。今后随着网络扁平化、互联网技术发展、DCS功能加强、系统集成技术成熟、ERP/MES/PCS 3层功能划分的管控一体化技术的发展，MIS和SIS的架构将会有所发展。

       目前SIS建设的热潮已经到来，自动化仪表行业的系统集成商应该参加到这个市场竞争中。

RS-23RS-422与RS-485的性能参数表：单工、半双工和全双工的定义如果在通信过程的任意时刻，信息只能由一方A传到另一方B，则称为单工。如果在任意时刻，信息既可由A传到B，又能由B传A，但只能由一个方向上的传输存在，称为半双工传输。如果在任意时刻，线路上存在A到B和B到A的双向信号传输，则称为全双工。RS-232的一些注意事项RS-232常用的三根针是5。其中5是地线，2和3是用来传数据的。
