摘要
采用虚拟仪器开发平台LabWindows/CVI进行上位机编程,基于微控制器ATmega64和A/D转换器AD7714,结合具有补偿式脉冲鉴相功能的变形采集调理电路及高精度的485总线驱动执行器接口,设计了万能材料试验机测控系统.实际应用表明,该系统运行可靠、运动控制精确、数据采集精度高,有较强的数据分析处理能力.
Programmed with virtual instrument development platform LabWindows/CVI in the host computer, based on the microcontroller ATemga64 and A/D converter AD7714, combined with distortion correcting circuit with compensative pulse phase-demodulation fimction and high-precision 485-bus driving actuator interface, a system of measurement and control for universal material testing machine was developed. The applications show that the system is reliable, has high precision of data acquisition and motion control, and also has powerful data processing ability.
