摘要
本文主要研究了基于激光多普勒效应实现带钢速度检测方法。在工业带钢生产的过程中,带钢运行速度的在线精确检测是一个重要问题。有效地检测出带钢的运行速度参数反馈给控制系统,从而使控制系统能够对带钢生产过程进行有效地控制,是生产高质量带钢的必要保证。因此,如何有效地测量带钢的运行速度是一个值得研究的问题。
首先分析了国内外带钢速度在线测量技术的优缺点,重点对基于激光多普勒效应实现带钢速度测量技术进行验证。同时根据带钢速度在线测量的要求,提出了切实可行的设计方案。包括：光学结构,信号检测和信号处理的硬件电路,同时搭建起用于测量的实验平台。最后多种求频率手段进行了分析。最终选择快速傅里叶变换求频率。本文通过FPGA实现FFT。
最后,通过实验验证了激光多普勒效应在带钢速度在线测量上应用的可行性。实验结论表明激光多普勒效应在带钢测速系统中的优越性,同时结合FPGA搭建快速高效的处理器,可以满足带钢的在线测量要求。
This paper makes a tentitve study on the method of belt-material velocity detection based on laser Doppler effect. In the process of belt-material manufacture in industry, it is crucial to accurately detected the velocity of Belt-material. Meanwhile, effectively detecting the parameters of belt-material velocity and feedbacking to the control system is necessary to ensure the production of high quality steel, so that the control systems can effectively control the process of Belt-material production. Therefore, how to effectively measure the velocity of belt-material is a problem worth researching.
This paper will initially analyze the advantages and disadvantages of the strip-line measurement technology at home and abroad, with emphasis on the verification on Doppler effect of laser-based measurement techniques to achieve the speed strip.At the same time, according to the request on strip speed on-line measurement, the author proposed a practical design, including:optical structure, signal detection, signal processing hardware circuitry, and erected the experimental platform for measuring. Then, the author analysed it by various means of obtaining frequency and ultimately chose the Fast Fourier Transform to seek frequency. In this paper, the autor realized FFT by FPGA.
Finally, this paper verified the feasibility of applying the laser Doppler effect to the strip-line measurement of the speed by experiment. Experimental results showed that the laser Doppler effect shared the superiority in the strip-line measurement of the speed, and the fast and efficient processor combined with FPGA can meet the requirements of strip-line measurement.
