摘　　要：针对传统的采用单片机来处理光栅信号的方法存在的不足,构建了一种基于TMS320VC5402的光栅信号处理实验平台.设计中DSP主要完成光栅信号的采集、滤波、细分、辨向和光栅信号的频谱分析,DSP处理的结果通过TL16C750实现的TMS320VC5402与PC机的串行通信来观察.采用DSP处理器构建的光栅信号处理实验平台解决了以往的光栅信号处理系统只能处理输入信号频率较低或者静态的光栅位移测量的问题.实验结果表明:基于DSP处理器的光栅信号处理平台,提高了信号的处理速度,进一步提升了光栅位移测量的应用范围,具有较强的工程应用价值.Aiming at the deficiency of traditional grating signal processing methods based on microcontroller,an experimental platform based on TMS320VC5402 is put forward.DSP mostly takes charge of signal gathering,filtering,subdivision,and direction judgment and spectrum analysis.Serial communication is realized between the TMS320VC5402 and PC by the chip TL16C750 and the test results can display on the PC.The experimental platform solves the traditional signal processing system of grating that can only handle lower frequency input signal or static grating displacement measurement problem.The experimental results show that the experimental platform based on DSP processors can improve signal processing speed and grating displacement measurement range of applications.The experimental platform has strong engineering application value.
