摘　　要：测试指挥显示系统需要将试验中的态势数据、关键设备测试数据、实时监视视频、指令进程数据、调度语音、气象数据、电磁环境参数、靶标毁伤数据等进行汇集并同步显示。为解决测试指挥显示系统进程之间的数据同步问题,提出一种基于多环形队列的共享内存异步传输数据同步方法,并在其基础上进行系统的设计实现和部分验证。该方法的工程应用可提高测试显示系统运行效率和可靠性,更好地服务于试验应用。The test command and display system needs to collect and synchronously display the situation data,key equipment test data, real-time monitoring video, instruction process data, dispatch voice, meteorological data, electromagnetic environment parameters, target damage data and so on. In order to solve the problem of data synchronization between test command and display systems, this paper presents a method of asynchronous data synchronization in shared memory based on multi-ring queue. On the basis of this method, the design, implementation and partial verification of the system were carried out. The application of this method in engineering can improve the efficiency and reliability of the test and display system, and better serve the test application.
