摘　　要：光电传感器当前已经在多个领域内发挥了重要作用,即通过对于各类检测信息的获得和传递,让控制系统可以根据获得的相关信息做出各项决策。然而,在实际运行过程中,会由于外部环境以及内部环境的同时影响形成噪声,不利于信号传输的质量保持。基于对小波变换计算方法的分析,该文研究了在光电传感器信号去噪技术中的应用方法,从而让信号的获得和传递质量提升。At present,photoelectric sensors have played an important role in many fields,which helps the control system make various decisions according to the acquisition and transmission of various detection information.However,in the actual operation process,noise will be formed due to the simultaneous influence of external environment and internal environment,which is not conducive to the quality maintenance of signal transmission.Based on the analysis of wavelet transform calculation method,this paper studies the application method in the signal denoising technology of photoelectric sensor,so as to improve the quality of signal acquisition and transmission.
