1、摘要中医经络学说经过数千年的研究和发展,已经取得很大的成就,逐步得到了世界各国的广泛认同和接受。但是传统中医学的经络情况不够直观。由于电信号特征较明显、易于获得,又是与经络密切相关的神经、循环系统的明显特征之一,因此,针对经络系统的电信号动态USB传输和波形的显示的设计,应能更有利于发现特征而触及本质。针对把微弱的经络信号转换为电信号,并且进行相应处理,使系统能够实时的反应经络图像的问题,基于USB技术的经络数据采集系统的设计严格遵循USB协议,采用TI公司生产的内核兼容8051带有闪存的高性能芯片C8051F32
2、0作为微控制器采集信号,该芯片自带的17路速度为200K的10位A/D转换器采集信号,同时该芯片还集成USB2.0接口,方便的完成了系统的硬件电路设计。本系统中单片机系统主要完成信号采集、数据通信和实现USB接口通信;微机完成数据接收、显示等功能。软件设计中采用C51语言编写数据采集程序和对USB接口芯片进行协议处理及数据交换的程序。上位机的数据处理程序应用visualbasic语言编写。关键词:C8051f320;数据采集;USB(通用串行总线);驱动程序AbstractChinesemeridiantheory
