摘要
采用工业组态软件FIX32作为SCADA学员系统的开发平台。为实现学员SCADA系统与变电站仿真系统其他子系统之间的数据通信 ,一方面系统采用 10 0M以太网 ,运用共享内存、同步锁和消息的进程间通信机制来完成各终端机与系统服务器之间的数据交换 ;另一方面借助FIX提供的DDEServer和DDEClient接口 。
The 100M Ethernet network contributes to the communication between the SCADA system and other terminal system As the development platform of SCADA system,FIX32 provides 3rd partner application with DDE interface So the scheme of the two level's communication in the SCADA of the simulate system is given Share memory,sync mutex and inter process messages are used to exchange data between the local communication inter process and the system database On the other hand,DDE Server/Client interface program carries through the communication between the terminal of monitor/control and the local communication inter process
