1、摘要本次模电课程设计是多路断线报警器,能同时对多个地点进行防盗监控,一旦某处的警戒线被盗碰断,则报警器会立即发出报警声,同时指示出发生盗情的地点。这对财产保管起到了良好的保护作用,随着社会的发展,报警器的使用相当频繁,一个物便价美的报警器自然更是被消费者所喜爱,技术越先进,百姓的生活也得到了提高,在一定程度上有益于社会的稳定和繁荣。本次课程设计电路由检测电路、LED指示电路、触发控制电路、音频振荡器和音频放大输出电路组成,检测电路是由电阻、非门、开关组成,LED指示电路是由发光二极管、电阻组成,触发控制电
2、路是由与非门、电阻、二极管,音频振荡器是由与非门、电阻、电容组成,音频放大输出电路是由三极管、电阻、扬声器组成。关键词报警器;监控;二极管;扬声器;三极管XIXABSTRACTTheanalogelectronictechnologycoursedesignisadisconnectedalarm,cansimultaneouslyonmultiplesitesofanti-theftmonitoring,onceacordonwasbroken,thealarmwillimmediatelysendou
