基于LabVIEW的USB设备无线测试系统设计

Design of Wireless Testing System for USB Device Based on LabVIEW

针对传统有线USB设备测试系统存在布线、单目标、通用性差等缺陷,设计一套基于LabVIEW的USB设备无线测试系统;系统以LabVIEW为软件开发平台,进行虚拟仪器前面板设计与后台程序的编写;利用无线数据收发模块及其余硬件设备,搭建上位机与设备间无线数据通讯的桥梁;以宏晶STC12C5A60S2单片机为核心控制器,通过引入USB总线接口芯片CH375扩展了USB-HOST功能,从而实现上位机和USB设备间数据的无线采集与传输;本系统主要应用于对USB设备的开发调试和测试过程。

Animing at disadvantages of the traditional USB equipment testing system,such as：single objective and poor universality,design a USB equipment wireless test system based upon LabVIEW.System with LabVIEW as software development platform for the virtual instrument front panel design and the preparation of the background program;Using wireless data transceiver module and other hardware equipment,build up the bridge between the host computer and the equipment of the wireless data communication;In STC12C5 A MCU as the core controller,through the introduction of USB bus interface chip CH375 extend the USB-HOST function,enabling wireless acquisition and transmission between the host computer and the USB device data.This system is mainly used in the development process of debugging and testing USB devices.
