基于PXI—6259的起重机参数检测系统设计

Design of Crane Parameters Detection System Based on PXI—6259

根据四倍频计数原理,利用LabVIEW图形化开发平台和PXI-6259数据采集卡,通过对调理后的增量式光电编码器输出脉冲进行定时采样、四倍频计数和算法处理,设计了一套可用于不同起重机设备的高精度参数检测系统,其中加入了数据实时存储模块,并在交流伺服电机控制系统中进行了验证。实验结果表明,该系统实时性好,测量准确,人机交互界面友好,并有效扩展了M法的应用范围。

According to four times frequency counting principle, by using of LabVIEW graphical development platform and PXI-6259 data acquisition card, a set of high precision parameters detection system which can be used for different crane equipment with the methods of time sampling, four times frequency counting and algorithm po- cessed to the regulated pulse of the incrementel photoelectric encoder. The system that joined the data real-time storage module was verified on the servo motor control system. As shown in the experimental results, the system has excellent real-time, high accuracy and friendly man-machine interface, and availably extend the application range of M method.
