智能测控系统USB接口功能的设计与实现

Design and Implementation of USB Communication for Intelligent Instrument

以静电探针测量系统为应用背景,提出并实现了主从设备之间的USB通信。在简要介绍系统结构和硬件设计的基础上,详细地阐述了一种通用的基于ARM微处理器的USB固件程序和Windows下USB驱动程序设计方法,并设计了一套主从设备通信交互协议。该设计已在静电探针测量系统中得到应用,对USB技术在智能设备中的应用具有很好的现实意义。

As langmuir probe measurement system for application background,this paper puts forward and implements USB communication between master and slave devices.It introduces the system structure and hardware design briefly,and expatiates a universal design method of USB firmware program for ARM micro processor and USB driver in Win-dows environment.Moreover,it also devised a suit of interactive protocol for the communication between master and slave device.This design has already been applied in langmuir probe measurement system and is very useful for ap-plying USB technology in intelligent instrument.
