摘要
信息传输管理平台是虚拟试验系统中的信息交互中枢,它的实时性能影响整个虚拟试验的运行。为了提高信息传输管理平台的实时性,分析了网络通信和本地数据特点,在VxWorks操作系统下采用任务划分和优先级设置、缓冲队列通信模式、信号量与中断服务程序优化等关键技术,在数据处理中应用哈希查找算法等2方面保障实时性。在虚拟试验中的性能测试与成功应用,表明该方法提高了现有信息传输管理平台的实时性,满足功能需求。
The information transmission management platform plays role of information interaction cetral in virtual test system,whose real-time performance affects the whole virtual test.In order to improve the real-time performance,analyzes its network transmission mode and local data characteristics,develops a method in both VxWorks opration system by task division with priority setting,buffer queue communication mode,semaphore,optimization in interrupt service routines and apllication of hash search aglgorithm in data processing.The performance test in virtual experiments with successful application,showes that the method improves the real-time performance and meets the needs.
