摘要
针对一般总线的数据采集设备都受到不支持热插拔、PC端口资源有限等因素的影响,使用起来很不方便的问题,设计了采用通用串行总线USB作为通讯总线的数据采集卡,系统采用具有在系统可编程(ISP)功能的微控制单元AT89S52和专用USB接口芯片PDIUSBD12,整个采集卡具有接口便捷、易扩展和低成本等特点。
The data acquisition system of general Bus dose not support hot inserting and pulling operation.And the Resources of PC Ports is limited.So we applied USB (Universal Serial Bus) as communication bus to design a data acquisition card.In this system.We used the MCU AT89S52 which has the function of ISP (In System Program) and the special purpose USB interface chip PDIUSBD12.The entire data Acquisition card is characterized by the merit of convenient interface, easy to expand and low cost.
