摘　　要：针对变电站SCADA仿真系统中动态交互式图形界面的复杂要求,采用FIX32工业组态软件作为开发平台构建监控及培训SACADA子系统。在监控终端与系统数据库之间采用两级通信方案。运用共享内存、同步锁和消息的通信机制通过局域网实现本地终端与服务器的数据通信:借助FIX提供的DDEServer和DDEClient接口,开发采用Server/Client模式的DDE通信程序以实现本地通信进程与监控画面之间的数据通信。FIX32is applied as the development platform to build the SCADA of substation SCADA simulation system to meet the requirements for the dynamic HMI.Two levels of communi-cation is adopted between the SCADA terminals and the system database.Share-memory,sync-mutex and inter-process messages are used to exchange data between the local terminals and the system database through LAN.With the DDE Server/Client interface program supplied by FIX,the Server/Client mode DDE communication program is developed to carry out the data communication between the monitors and the local communication inter-process.
