摘要
采用硬件描述语言VHDL(very high speedintegratedcircuithardwaredescriptionlan guage)设计出现场可编程门阵列 (FPGA)芯片 ,实时提取 3 2通道的声发射信号的两个特征参数 (到达时间和声发射振铃计数 ) 。
An FPGA(field programmable gate array) chip was developed with VHDL(very high speed integrated circuit hardware description language) for real time picking up of two acoustic emission parameters(arriving time & ring count) in 32 channel acoustic emission testing, which could be used to realize source location and intensity evaluation.
