摘要
给出了一种新的旋转变压器轴角/数字转换电路,采用NIPXI-6070E多功能数字采集卡、PXI总线、通用计算机以及图形化编程语言LabVIEW构建了旋转变压器轴角/数字转换系统。通过MATLAB仿真可知该系统可达到精度要求。这种基于虚拟仪器技术的数据采集、处理系统具有性价比高、开发周期短、易于集成和扩展的特点,有一定的应用价值。
A new circuit of resolver R/D conversion is presented, and the circuit is composed of NI PXI- 6070E multi- functional DAQ board, PXI bus, PC and LabVIEW. By simulating in MATLAB it can be found that the system can meet the precision require-ment.The Virtual- Instrument- based data acquisition and processing system is inexpensive and easy to build, integrate and extend.
