飞行试验是极具风险性的试验工程,遥测数据传输为飞行试验提供重要的测试数据传输通道,便于指挥员决策。对于风险较高的试验科目,地面采用多套遥测站同时接收试验机数据,试飞工程师只能根据观察各个遥测站的信号质量,手动选择一路作为数据源。网络化遥测数据最佳源选择技术利用嵌入式平台将数路遥测数据融合后以网络包形式输出,实现无人值守,智能选择、提高系统处理效率。 Flight test is a very risky test project. Telemetry data transmission provides an important test data transmission channel for flight test to facilitate commanders decision-making. For high-risk test subjects, the ground using multiple sets of telemetry stations while receiving test machine data, test engineers can only observe the signal quality of each telemetry station, manually select all the way as a data source. The best source selection technology for networked telemetry data uses embedded platform to combine the digital telemetry data and output it in the form of network packet to realize unattended and intelligent selection and improve the system processing efficiency.
