摘要
对于将监视信息处理与冲突探测分立为2个功能模块的空管自动化系统,系统航迹输出和冲突探测双方时序以及数据处理过程均相互独立。为了保证冲突探测模块能够及时响应监视信息处理模块输出的航迹信息,并且冲突计算不受航迹更新过程的影响,提出了一种新的冲突探测航迹队列更新方式。利用内存映射机制在通信进程与冲突探测进程间传输系统航迹,并根据冲突探测进程所处的运行状态决定航迹队列的更新方式。运行结果表明,所提的系统航迹队列更新方式实用有效,能够保证冲突探测使用的系统航迹保持最新的更新状态。
For air traffic control automation system w hich conflict detection unit is separated from the surveillance data processing unit ,the time sequence and data processing between conflict detection and system track output are independ‐ent .In order to ensure prompt response to track information w hich surveillance data processing unit outputted ,and con‐flict calculating without affected by the updating process of track ,this paper proposes an novel updating method of sys‐tem track queue in conflict detection . This method takes advantage of mapping mechanism between communication process and conflict detection process to transmit systems track ,and decides the way in which the track queue update ac‐cording to the operating state of conflict detection process .Operation results indicate that the proposed method is practical and effective and has the intrinsic capability of keeping system track used for conflict detection the latest status .
