摘要
新工科背景下,高校电子信息科学和通信工程专业对通信原理实验教学的灵活性和综合性提出了更高的要求。针对现有采用CPLD核心的通信原理实验系统使用灵活性差、不能满足通信原理综合实验需求等问题,该文设计了一种新型程控通信原理实验系统。采用分频器联合单片机的结构产生实验系统所需的各种时钟及编码信号,能够通过按键和上位机实现对非同步正弦信号波形、各实验系统的编码时钟频率和输入数字信号码型的程序控制,并能够通过显示屏显示这些信号的参数信息。利用该实验系统能够有效提高通信原理实验的教学效果,满足新工科建设发展的需要。
Under the background of new engineering,the specialties of electronic information science and communication engineering in universities put forward higher requirements for the flexibility and comprehensiveness of experimental teaching of communication principles.Aiming at the problem that the existing communication principle experiment system with CPLD core is not flexible enough to meet the demand of communication principle comprehensive experiment,a novel program-controlled communication principle experiment system is designed.The structure of frequency divider combined with MCU is adopted to generate all kinds of clock and coding signals needed by the experiment system.The program control of the non-synchronous sine signal waveform,the coding clock frequency of each experiment system and the code pattern of the input digital signal can be realized through the host computer or the keys on the system.The parameter information of these signals can be displayed through the screen on the experiment system.The whole experiment system adopts modular design,which is flexible in use and convenient in maintenance.Using the novel program-controlled experiment system can effectively improve the teaching effect of communication principle experiment and meet the needs of new engineering construction and development.
