飞行试验振动信号具有采样率高、数据量大、处理复杂的特点,在现有条件下,通过遥测链路很难将大量的振动数据实时传输至地面监控系统。针对试飞测试的需要,结合某型号的试飞关键技术攻关研究,突破试飞振动数据实时处理系统的一些关键技术,对被试飞机的振动信号进行实时分析,将分析结果实时发送至地面监控系统,以减小遥测传输带宽,真正实现高采样信号振动数据的遥测实时监控。 Flight test vibration signal with high sampling rate, large amount of data, complex processing characteristics under the existing conditions, it is difficult to transmit a large number of vibration data through real-time telemetry link to the ground monitoring system. According to the need of test flight test, some key technologies of flight test of a test flight are explored, and some key technologies of real-time processing system of test flight vibration are explored. The real-time vibration signal of test aircraft is analyzed in real time and sent to ground monitoring system Reduce telemetry transmission bandwidth and truly realize real-time telemetry monitoring of high-sampled signal vibration data.
