Research and application of the real-time telemetry original data connecting method

摘要:

实时遥测数据处理系统借鉴了事后处理中多站原始数据对接设计思路，实现了实时遥测原始数据对接。实时对接数据处理具备了实时处理的速度和事后处理的质量，提供了一种全程连续的结果，并能克服部分设备数据散乱造成的参数误解问题，更好地满足了任务需求。实时对接技术是实时遥测数据处理系统中的亮点和难点，本文提出并实现了以遥测数据帧为粒度的实时多站遥测原始数据对接方法，分析了实时对接中面临的现实问题和困难，给出了方法实现的关键步骤、核心算法和具体流程，并指出了与事后对接的相同点和不同点及难点。最后，对方法的应用效果分别同单站设备结果、事后对接结果进行了比对分析，比对结果表明了该方法的可靠性、有效性和鲁棒性。该方法已多次应用于实时任务中，效果良好。

Abstract:

The real-time telemetry data processing system has realized the real-time origin data connecting based on design idea of post-mission data connecting. The real-time connected data processing has the speed of real-time data processing and the quality of post-mission data processing, and offers the whole course result, and can resolve parameters wrongly due to scattered data, so it can better satisfy the task demands. Owing to the real-time data connecting method which is brilliant and difficult in the real-time processing, the paper puts forward and carries out the real-time telemetry original data connecting method for many devices, and analyzes the realistic problems and difficult in the connecting course, and offers the key steps, core algorithm and the concrete flow of the method, and points out the difference and difficulty with the post-mission data connecting method. At last, its application effect has been compared with the post-mission connected data result and single device data result, and compared results show the relia-bility, efficiency and robustness of the real-time telemetry original data connecting method, which has been used in data processing in many tasks and has received perfect effect.
