摘要
用PCI2006数据采集卡设计消弧线圈控制系统的数据采集模块,研究它在控制系统中的作用。首先介绍PCI2006采集卡的基本功能,然后设计了一种链表式的数据存储方法。最后,根据注入法检测对地电容电流的原理,搭建了硬件平台,并在VC平台上完成了程序开发。试验结果表明,系统测得的对地电容电流与现场用两点法测得值相近。
The PCI2006 data acquisition card is used as a system data acquisiton module in the Petersen-coil control system. The basic functions of the PCI2006 are introduced. A list data storage method is proposed. According to the principle of the signal injection method, the hardware system is designed, and its procedures are developed on VC platform. The experimental results show that values of the capacitive current-to-ground measured with this method approximate to the field values measured with the two-point method, which proves that this system is reliable.
