基于遥测全帧的延时数据弥补方法研究与应用

摘要

利用延时数据弥补乱散或丢失的实时数据是遥测数据处理的重要组成部分.针对逐点弥补方法需人工参与、弥补过程复杂等状况,提出以遥测全帧分路数据为一个基本单元进行延时弥补的处理思路,介绍两种具体的基于全帧弥补方法的实现步骤,给出方法实现中的关键算法,并分析指出延时弥补方法的优化方向.对实际应用效果的分析充分表明了基于全帧的弥补方法的有效性和可靠性.方法已多次应用于飞行任务数据处理,效果良好,实现了延时重发的目的,满足数据处理要求,同时提升了数据处理速度和质量.%The remedy of disordered and lost real-time data using delay data is an important component of telemetry data processing. The remedy method based on sampling point one by one demands manual work and is complex. This paper puts forward a new processing idea of data remedy based on the shunt data in one telemetry frame, and proposes two remedy methods whose steps and key algorithms are given. Further more, the optimized directions of the remedy methods are pointed out. The application results show the efficiency and reliability of the proposed remedy methods. The two remedy methods have been used in the data processing of many aviation tasks, and worked well. The demand of data processing is satisfied and the speed and quality of data processing are improved.
