摘要
本研究主要针对机载试飞测试系统的无线化工作,以解决试飞测试发展过程中所面临的线缆繁杂、布置紧张、装卸耗时、维护困难等问题。试飞测试系统设备包括各类传感器以及存储器,依托星闪短距无线通信技术低功耗、低时延、高吞吐、高可靠的优势特征,设计定制化轻小型短距无线通信模组,将传感器、存储器与定制化无线模组集成,传感器采集的数据经模数转换后通过无线空口传输至存储器,实现试飞测试数据的无线化记录以及试飞测试系统的无线化。测试结果表明,在实验室条件下,定制化无线模组的速率可达4 Mbps以上,传输时延在3.5 ms以内,相关指标能够满足机载试飞测试数据记录的性能需求。
This paper focuses on the wireless transformation of airborne flight test systems,which can solve the problem such as complex cabling,difficult installation and removal,time-consuming setup,and maintenance difficulties encountered during the development of flight testing.The flight test system equipment includes various sensors and storage devices.Leveraging the advantages of SparkLink wireless communication technology—such as low energy,low latency,high throughput,and high reliability—customized compact short-range wireless communication modules were designed.These modules were integrated with sensors,storage devices and customized wireless module,enabling analog-to-digital converted sensor data to be transmitted over the air to the storage units.This achieves wireless recording of flight test data and a wireless flight test system.Test results under laboratory conditions demonstrate that the customized wireless modules can achieve data transmission rates up to 4 Mbps with a transmission delay below 3.5 ms,meeting the performance requirements for airborne flight test data recording.
