基于MSP430和ZigBee的玻璃破碎检测器

系统提出了基于MSP430和ZigBee的远程玻璃破碎检测报警方法。为了设计一种高精度低成本的玻璃破碎检测系统,设计算法以典型玻璃破裂信号的特征分析结果为基础,通过板载蜂鸣器和ZigBee来远程传输玻璃破裂警报。玻璃破裂检测器的处理程序主要分为两个阶段,第1阶段主要对麦克风所采集到的信号进行滤波和特征提取,第2阶段通过对第1阶段的特征进行判断比较,达到检测玻璃破碎的功能。通过对典型的破璃破碎信号进行仿真分析和实际实验,实验统计结果表明,系统对玻璃的检测的准确率达到95%以上,相比现有的破璃破碎检测器准确率有了很大提高。

Glass breakage detector based on MSP430 and ZigBee

The system proposed a remote glass breakage detection and alarm method based on MSP430 and ZigBee. In order to design a high-precision and low-cost glass breakage detection system, the design algorithm is based on the characteristic analysis results of typical glass breakage signals. Remotely transmit glass break alarms via onboard buzzer and ZigBee. The processing procedure of the glass rupture detector is mainly divided into two stages. The first stage mainly filters and extracts the signals collected by the microphone, and the second stage judges and compares the characteristics of the first stage to detect the broken glass. through the simulation analysis and actual experiment of the typical broken glass broken signal, the experimental statistics show that the accuracy of the system detection of the glass reaches more than 95%, which is much better than the existing glass broken detector.
