摘　　要：介绍了一种用于4通道温度采集的PC104采集卡的设计。文中说明温度调理芯片AD7711的使用方法及其与AT89C55WD单片机的接口电路,阐述AT89C55WD单片机与PC104总线间的通讯方法,包括硬件接口电路和软件程序设计及其注意事项。该温度采集卡提供一定的数据缓冲能力和查询中断兼备的工作方式,使得它的功能比较强大和全面,并且非常灵活。其设计思路值得类似的采集卡借鉴。实际运行结果表明,该采集卡的设计是成功的,并且工作可靠。This paper introduces a 4channel temperature acquisition card based on PC104 bus. The characteristics, register structure and interfaces are described. Interface technology AT89C55W to AD7711 and its communication with PC104bus of the collecting-dates system are presented in detail, including hardware circuit, software and notice. This temperature collection card has date buffer storages and provide two usual working modes, the inquire mode and the interrupt mode. This design is worth of using for reference by other similar projects. According to the practical resuit, this design is successful and credible.
