摘　　要：传统造纸车间网络通信弱信号增强方法由于仅提取了造纸车间网络通信弱信号的单一参量,导致对其的增强效果不佳。为解决这一问题,设计一种基于改进小波变换的造纸车间网络通信弱信号增强方法。首先,利用信号采集设备采集造纸车间网络通信信号,并对采集信号进行预处理;其次,计算感知造纸车间网络通信弱信号,在传统小波变换的基础上对其进行改进,并由此提取造纸车间网络通信弱信号的频率参量、幅度参量等多个信号参量;最后,利用提取的信号参量,将相似信号进行叠加,以完成弱信号增强。实验结果表明,与以往的造纸车间网络通信弱信号增强方法相比,设计的基于改进小波变换的造纸车间网络通信弱信号增强方法在实际应用中信号强度更高,增强效果更好。The traditional weak signal enhancement method of paper workshop network communication only extracts a single parameter of the weak signal of paper workshop network communication,resulting in poor enhancement effect.To solve this problem,this paper designs a weak signal enhancement method based on improved wavelet transform for paper workshop network communication.Firstly,the signal acquisition equipment is used to collect the network communication signals of paper workshop,and the collected signals are preprocessed.Secondly,the weak signal of paper workshop network communication is calculated,which is improved on the basis of traditional wavelet transform,and several signal parameters such as frequency parameter and amplitude parameter are extracted from it.Finally,by using the extracted signal parameters,similar signals are superimposed to complete the weak signal enhancement.The experimental results show that the paper shop network communication weak signal enhancement method based on improved wavelet transform has higher signal strength and better enhancement effect in practical application.
