摘　　要：为准确检测飞行器设备的工作状态,设计了一种能够提供多种指令信号源的遥测系统,以FPGA为中央控制单元,通过以太网接口与上位机进行通信,传输速率可达40 Mbit/s。根据通信协议,结合外围硬件电路,为飞行器测试提供所需参数。经试验表明,此系统产生带电指令信号幅值稳定,不带电指令响应精准。该系统可靠性高、扩展方便,具有很强的实用性。Aimed at test for the working status of aircraft accurately,a telemetry system was designed,which can provide various types of instruction signals. The logic control was completed by FPGA,and through Ethernet to communicate with the host computer,the speed of it can be 40 Mbit / s. On the basis of communication protocol combining with peripheral hardware,test parameters are provided for aircraft. The experimental results proved that the range of charged instruction signals produced by this system is stable,and the respond of non-charged instructions is accurate. This system has the advantages of reliability and interchangeability,which occupies a powerful practicality.
