基于PCI总线的DDC系统设计与实现

Design and Realization of DDC System Based on PCI Bus

介绍基于PCI总线多功能数据采集卡(PCI-1711)的管式电阻炉温度DDC系统的设计与实现。以具有A/D、D/A转换功能的数据采集卡,配以外围电路,实现工业现场信号的测量及系统模拟信号的输出。以工控组态软件(MCGS)实现数据采集卡的驱动,并编写制作出用户界面友好、控制算法灵活,具有工程应用价值的历史报表、直观的实时曲线和历史曲线。

This paper introduces the design and realization in tubular resistance furnace temperature DDC system based on PCl bus multi-function data acquisition card （PCl-1711）.Using the card of A/D and D/A conversion function,and the external devices,and it realizes the scene signal measure and the simulate signal output in industry.Using To the controls configura- tion software （MCGS） to driver data acquisition card,it has designed the compose a user-friendly interface and a vivid algorithm,the historical report form of the application value,the direct-viewing real-time curve and the historical curve.
