摘　　要：飞行器弹射试验过程中,数据记录器通过地面检测单元的长线传输接口与地面设备进行通信。结合试验过程中的特殊环境和工作要求,对地面检测单元长线传输接口的电磁隔离、启动命令、时钟信号和数据传输进行抗干扰设计;并通过大量实验考核、验证其设计的可靠性。该系统已成功参试多次大型地面试验,工作可靠、性能良好。In aircraft ejection trail, the data recorder communicate with the ground equipment by long-term transport interface of ground detection unit. According to the special working environment and requirements in the test process, an anti-interference design is produced for electromagnetic separation, startup command, the clock signal and data transmission, and through a large number of experiments examine and verify the reliability of its design. The system has been successfully participated in many large-scale ground trails. Its performance is reliable and stable.
