摘　　要：针对电子系统设计教学中存在缺乏数模混合系统设计能力的问题,设计了基于FPGA的惯导姿态数据采集模数混合实验系统。该系统包含隔离及整形电路单元、AD转换电路单元、多路脉冲信号滤波单元、高精度无缝计数单元及系统协调控制单元等。通过该系统的设计,引导学生掌握从单元电路到系统的设计能力,培养学生分析问题与解决问题的能力,提高学生的工程应用能力。实践结果表明,该实验可大大激发学生的学习兴趣,提高电子系统设计课程的教学效果。Aiming at the lack of design capability of complex digital-analog hybrid system in the teaching of electronic system design,a hybrid experimental system of inertial navigation attitude data acquisition module based on FPGA is designed.The system includes isolation and shaping circuit unit,AD conversion circuit unit,multi-channel pulse signal filter unit,high-precision seamless counting unit and coordination control unit and so on.Through the design of the system,the students are guided to master the design ability from the unit circuit to the system,cultivate the students’ability to analyze and solve problems,and improve their engineering application ability.The practical results show that the experiment can stimulate students’learning interest and improve the teaching effect of electronic system design course.
