摘要
超高速动平衡测试系统可以对旋转机械在超高速旋转的工作条件下进行动平衡检测。介绍了ADC0820的主要性能特点和它在数据采样模块中的应用。以ADC0820为核心的采样模块只负责数据采样,提高了系统检测的速度与精度。模块采用分时存取系统,并利用整周期采样控制电路实现数据整周期采样,分析了ADC数据采样的时序控制,并验证了其可行性。
The super high-speed dynamic-balance test system can high-precision test the dynamic imbalance of the super highspeed rotating machinery in their working conditions. This paper described the ADC0820＇s features, characteristics and the application in the data sampling module. The ADC0820 in the sampling module was only responsible for sampling data, which improved the speed and accuracy of the system detecting. The module used the data access time-sharing system, and it can sample the entire cycle of control circuits to realize data sampling of the whole cycle. It analyzes the timing control of ADC data sampling, and validates its feasibility.
