摘　　要：文章在MATLAB GUI编程的基础上,设计了基于MATLAB GUI的声发射信号特征参数分析平台。该平台用于分析混凝土构件在损伤状况下释放的有效声发射信号参数随时间或外变量变化的情况,从而得到声发射源的活动情况和发展趋势。仿真试验表明,该平台能够反映出预应力混凝土构件破坏过程中的特征信息,为实际远距离在线结构健康的监测提供了实际依据。Based on the MATLAB GUI, a platform for acoustic emission signal parameters analyses has been developed in this paper. The platform is used to analyze the parameters of the effective acoustic emission signal which is released from the injured reinforced concrete structures, and thereby find the situation of the source of acoustic emission activities and its development trends. The platform may be independent of the MATLAB environment to run. Simulation results show that the platform can reflect elements of prestressed concrete beam characteristics in the process of destruction of information, and provide a practical basis for online structural health monitoring of the actual distance.
