According to the characteristics of AE signals of the metal early micro crack in the process of deep drawing, the parameters to identify the crack signal are selected. The wavelet packet are adopted to resolve the AE signals with complex background noises and feeble crack characteristic, as well as the time series analysis method is applied to established the AR model of the resolved signal and to...
This paper mainly presents zinc-air battery on-line detection system. The research of the on-line detection system was based on zinc-air battery production line. Using arm embedded microprocessor as the detection system core. Using sensors detect material, humidity and temperature, roller pressure in the production process, design the hardware and software platform of this detection system, and achieve...
