摘要
结合测控技术与仪器专业的实验教学需求,以及学生在电子电路设计方面的设备需要,设计出一款集成有模拟信号采集、函数发生、数字信号采集及发生、以及其他常用模块功能的辅助电子电路设计开发平台.针对该平台软硬件系统设计做了详细叙述:该平台基于虚拟仪器技术,通过平台携带的数据采集卡将采集到的模拟量及数字量上传至PC端,通过PC端软件进行数据处理,或将需要的函数波形及数字量通过平台进行输出.平台与PC通过USB进行通信.并且考虑到用户的实际需求,在PC端用户程序中,开发一个虚拟串行接口,用户可根据自己的实际需求编写相应软件,通过虚拟串口与平台进行通信.
Combined with the experimental teaching requirements of the measurement and control technology and the instrument specialty,and the needs of the students in the electronic circuit design,a design and development platform integrated with analog signal acquisition,function generation,digital signal acquisition and occurrence,and other common module functions is designed.This paper mainly aims at the design and development of the auxiliary electric circuit.The hardware and software design of the platform is described in detail.The platform is based on the virtual instrument technology.Through the data acquisition card carried by the platform,the analog and digital quantities are uploaded to the PCend,data processing is carried out through the PC end software,or the function waveform and digital quantity needed are output through the platform.The platform is communicated with the PC through the USB.And the actual needs of the users are taken into account in PC.In the end user program,a virtual serial interface is developed.Users can write corresponding software according to their actual needs,and communicate with the platform through virtual serial port.
