【摘要】：为满足铁道信号综合实验课程的研究性实验教学需求,考虑列车运行条件下的静态特性与动态特性而设计了应答器上行链路信号实验系统。基于虚拟仪器软件技术设计了人机交互模块,以STM32处理器、AD9854芯片为核心设计了信号发生模块,将示波器作为显示测试模块对输出信号进行测试验证,输出信号动态特性实测值与理论值误差在5%以内,能够满足实验教学需要。应用表明,该实验系统便于学生在实验室静态环境下掌握列车运行条件下应答器上行链路信号的波形特性,使学生实践能力和科学素养获得提高,取得了良好教学效果。
[Abstract]:In order to meet the requirement of research experiment teaching of railway signal synthesis experiment course, the uplink signal experimental system of transponder is designed considering the static and dynamic characteristics of train operation. Based on the virtual instrument software technology, the human-computer interaction module is designed. The signal generation module is designed with STM32 processor and AD9854 chip as the core. The oscilloscope is used as the display test module to test and verify the output signal. The error between the measured value and the theoretical value of the output signal is less than 5%, which can meet the needs of experimental teaching. The application shows that the experimental system is convenient for students to master the waveform characteristics of uplink signals of transponder under the condition of train running in the static environment of the laboratory, so that the students' practical ability and scientific literacy can be improved, and good teaching results have been obtained.
