this program used to acquire data through pc mic with 8khz sampling frequency. it collects data upto 2sec s duration, (can be varied) and reprodued

基于matlab编写程序，可以用于基于无线传感器和物联网系统的土木工程结构的健康监测数据采集和分析。(Based on MATLAB programming, can be used in health monitoring data acquisition and analysis of civil engineering structure of wireless sensor and the Internet of things based on system..)

This is for demo. Please have a look on to it.

说明：  人工势场法程序代码，用matlab编写，简单易懂(the code,you can use it to set the obstale imformation ,the length and so on)
