摘　　要：针对日常家庭生活中经常容易出现的失火、被盗现象,设计了一种玻璃破碎报警器件,来提高安全防护的效果。文中通过选用压电式传感器MPX4115A来感应外界信号的变化,将感应信号传递给单片机控制系统,最终的信号以蜂鸣和光闪两个方面来实现较好的报警效果。In this article,the device that can improve the safety and the protection is designed under the conditon of fire disaster and theft disaster in our everyday life.Firstly,the piezoelectric sensor MPX4115A is used to response the change of outer signal,then the output of the MPX4115A will be transferred to the singel-chip controlling system,the alarming effect will be realized by buzzer and LED.
