摘　　要：针对飞行器控制系统半实物仿真试验中,原有伺服机构摆角采集系统模拟量输出干扰大的问题,设计实现了一种数字式摆角采集系统。数字式摆角采集系统采用光电码盘传感器,传感器输出的是数字量,解决了干扰大的问题。数字化伺服机构摆角采集系统主要包括光电码盘传感器、码盘数据采集板卡、摆角采集计算机及通信线缆等部分。其中,码盘数据采集板卡通过FPGA编程实现EnDat通信功能,按照EnDat协议与光电码盘传感器连接,实时采集和处理传感器信息。通过试验结果表明,该系统能够快速上传摆角采集值,提高了采集精度,具有良好的实时性。In the hardware-in-the-loop simulation of aerocraft control system, the output of servo angle measurement is analog signals, which is disturbed by the environments easily. Aiming at solving this problem, the digital servo angle measurement system is designed, which contains photoelectric position encoder, data transforming circait board, data processing computer and communication cables. The data transforming circuit board is connected with photoelectric position encoder through FPGA by EnDat standard to gather and process position data in real team. Through experimentation tests, the position data can be gath- ered and processed quickly and the data acquisition precision is improved fairly with real-time by using the digital servo angle measurement system.
