摘要:
本文介绍了具有自适应极值搜索功能的数字极性相关测试系统。在配备相应的传感器后,可用以测量平均流速、流量及距离、深度等。文中分别讨论了脉冲乘法器、数字积分器、双通道数字可调延时电路和自适应逐次比较极值搜索系统的设计,并详细分析了测试系统的性能,指出该系统的测量精度可达1%。文中最后还列出了实验所得的数据和照片,为该系统的实际使用提供了一定的实验依据。
Abstract:
In this paper, the digital polar correlation measuring system which possesses the adaptive function for seeking maximum value is introduced. When appropriate transducers are installed, it may be applied to the measurement of distance, depth, average flow velocity and mass flow rate. In addition, the design of pulse multiplier, digital integrator, double-channel digital adjustable delay circuit and adaptive successive comparison system for seeking maximum are described. the performance of The system is also analysed in detail, its accuracy may be as high as 99%. At the end of the paper, the experimental results are presented, which may be served as a reference for practical applications of the system.
