基于DDS和WPF技术的试飞实时监控系统设计

针对以服务为中心的客户端服务器(C/S)架构监控模式存在着数据融合困难、传输协议单一、扩展灵活性差等不足,将数据分发服务(DDS)技术引入到试飞实时监控系统中,结合WPF图形引擎技术形成了一整套解决方案。在完全兼容当前架构规范的前提下,采用DDS技术作为数据传输中间件,有效提高了试飞监控系统的实时性,加强了多源数据融合粒度,降低了试验资源的集成难度；采用WPF图形引擎技术构建实时监控可视化编辑平台,最终实现了空天地综合监控环境下多源数据接收、处理、分发以及可视化展示等关键技术。此方案已经在飞行试验地面实时监控中得到了成功应用。

Design of real-time monitoring system for flight test based on DDS and WPF technology

In view of the difficulties of data fusion, single transmission protocol, and poor flexibility of extension in the service-oriented client-server (C/S) architecture monitoring mode, the data distribution service (DDS) technology is introduced into the flight test real-time monitoring system, and a complete set of solutions is formed by combining the WPF graphics engine technology. On the premise of fully compatible with the current architecture specifications, DDS technology is used as the data transmission middleware, which effectively improves the real-time performance of the flight test monitoring system, strengthens the granularity of multi-source data fusion, and reduces the integration difficulty of the test resources; WPF graphics engine technology is used to build the real-time monitoring visual editing platform, and finally realizes the multi-source data reception in the air space integrated monitoring environment , processing, distribution, visual display and other key technologies. This scheme has been successfully applied in the ground real-time monitoring of flight test.
