摘要
针对组建虚拟仪器实验室的数据采集部分,采用USB数据采集的设计方案。采集系统硬件选用Philips公司的增强型单片机P89C58×2及PDIUSBD12为核心器件;利用单片机完成A/D转换,调用USB固件发送采样数据到USB总线;上位机在Windows2000平台上利用VC6.0、Windows2000 DDK、DriverWorks对虚拟仪器数据采集卡WDM驱动程序进行开发;利用LabWindows/CVI开发上位机监控界面。整个系统调试成功,可以作为数据采集模块供虚拟仪器实验使用。
Aiming at setting up the data collection for virtual instrument laboratory, the design scheme of USB data collection is adopted. The enhanced single chip computer P89C58 ×2 and PDIUSBD12 from Philips are used in the hardware of USB data collection device as the core. The data sampling is realized by P89C58× 2, and then the sampling data are sent to USB bus by USB firmware. On the Windows2000 platform of host computer, by using VC6.0, Windows2000 DDK and DriverWorks, the WDM driver of virtual instrument data collection device is developed, and LabWindows/CVI is used to develop monitor interface of the host computer. The whole system is tested successfully, the device can be used in virtual instrument experiments as data collection module.
