摘要
本文针对变电站SCADA仿真系统,基于工业组态软件FIX32作为其开发平台,在SCADA系统和变电站仿真系统之间实现了数据通信,一方面为了能够满足带宽和速度的要求,在系统服务器和终端机之间进行数据的交换,采用了100M的以太网,同时运用了同步锁、内存共享等机制技术保证系统稳定可靠的运行。另一方面,基于工业组态软件提供的Client接口和DDE Server接口,形成的Server/Client组合模式的DDE通信程序来完成本地通信进程和监控画面之间的数据的通信。测试结果表明,该系统通信耗时较短,对于服务器的占有率也比较低,完全能够满足变电站系统要求。
The substation SCADA simulation system for the industrial configuration software FIX32 is used as a development platform, in order to realize the student SCADA system, between the substation simulation system data communication.On the one hand, in order to meet the requirements of bandwidth and speed and the exchange of data between the server and terminal, the 100M Ethernet,a synchronization lock and memory sharing mechanism are used to ensure stable and reliable system operation. On the other hand, based on the industrial configuration software Server DDE and Client interface, the Server/Client mode DDE communication program are formed to achieve the communication between the monitor screen and the data of the local communication process.The test results show that the system communication time is short and the server share is low, which meets the requirements of the substation system
