摘　　要：基于USB接口通讯的多传感器数据采集系统以EZ—USB控制器为核心,由EZ—USB经控制电路实现对模数转换的控制,从而将被测系统中各传感器检测到的参数通过USB接口输入到计算机并显示出来。系统硬件主要采用以AN2131QC为核心的USB接口电路和以模数转换器AD7938为核心的USB设备功能单元电路。系统软件采用Ke il C51语言编写芯片固件程序、采用VC++语言编写USB设备驱动程序和W in32应用程序。The data acquisition system of sensors based on USB communication took an EZ-USB controller as the core. And the EZ-USB controlled A/D conversion by its control circuit. Thus the parameters detected by sensors were imported to the computer and displayed. The core of USB interface circuit was AN2131QC, and the core of USB functioning circuit unit was AD7938. The firmware program of the system was written by Keil C51 language and the USB driver and Win32 application by VC ＋＋.
