管制员操作记录与交互式回放系统

摘要

To achieve the recording and playback of controller operations in ATC (air traffic control) systems ,and considering the importance of human-computer interaction during playback ,an interactive replay technique was introduced .An improved ap-proach was proposed by using original operation data .This approach only recorded the modified variables of subject software in the physical memory .Hence it implemented interactive replay and saved disk space .In addition ,the replay process of operation data kept synchronous with radar data and voice data .The feasibility and efficiency of the approach was verified by the test on the ATC system .%为实现空管自动化系统管制员操作的记录回放，考虑到人机交互在回放过程中的重要性，提出一种交互式回放技术。设计基于原始操作数据的记录方法，解决记录文件过大的问题。通过只记录操作结果的方式，实现管制员操作的交互式回放，提升磁盘空间利用率，与雷达数据和话音数据同步回放。在自主研发的通航空管自动化系统上的实际回放效果验证了该方案的可行性和高效性。
