基于声音-压力的多通道角钢材质检测系统硬件设计
Hardware design of multi-channel material detecting system via sound and pressure signal
摘要
Abstract
Aiming at the phenomenon that angle steel mixing causes misuse of types,the multi-channel steel material detection system is developed based on characteristics of different punching sound and shearing pressure for different material of angle steel.Firstly,the design scheme of the angle steel material detecting system is determined by analyzing the detection theory in the process of angle steel.Secondly,the overall scheme of hardware circuit is put forward,the hardwares are selected,the front panel interface and the internal circuit are arranged reasonably,and the hardwares of the multi-channel angle steel material detection system of sound and pressure are encapsulated.On-site installation tests are carried out with the system soft-ware.The results show that the system can complete the on-line detection of multi channel signal acquisition,processing,anal-ysis and recognition,which has a reference value for improving the efficiency of material detection of the angle steel.关键词
