目前智能站存在多种通信规约并行的情况,为减轻现场调试工作量,需要对多种设备的通信规约进行检测比对。设计了一种面向智能变电站设备的多种规约集成一体化的通信测试比对系统,采用基于PXI总线的硬件设计技术和功能软件组态实现技术,建立反映通信测试进度及测试内容的实时库,预配置实施通信规约测试的模板,协调各类规约及设备的通信测试进程,实现基于实时库的不同规约的通信内容同步比对,最终达到通信规约测试的目的。
At present, intelligent stations exist in parallel with a variety of communication protocols. In order to reduce the workload of on-site debugging, the communication protocol of multiple devices needs to be checked and compared. A multi-protocol integrated communication test and comparison system for intelligent substation equipment is designed. The hardware design technology and functional software configuration technology based on PXI bus are used to establish the real-time database which reflects the progress and test content of communication test. Pre-configure the implementation of the communication protocol test template to coordinate all types of protocols and equipment, communication testing process, based on real-time library synchronization of different protocols for the synchronization of the content, and ultimately achieve the purpose of communication protocol testing.
