摘要
从剖析USB协议和工作原理入手,采用"模块化"思想,提出了基于USB总线的虚拟仪器系统的分层结构设计方案和关键的实施要点,成功地开发了USB接口模件和基于USB总线的信号发生/采集设备。借助计算机,测试系统可提供面向用户接口、面向总线接口和面向数据处理的虚拟仪器功能。
Analyzes Universal Serial Bus's protocol and its keystone first,adopting 'Modularization'idea,the Virtual Instrument System's hiberarchy-designing scheme and pivotal implementing kernel based on USB are presented.Then develop successfully a USB interface module and a signal generating/collecting device based on USB.By dint of computer,the test system can provide Virtual Instrument's function of user interface oriented,bus interface oriented and data processing oriented.
