多路断线报警器设计课程设计.doc

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。 这对财保管起到了良好的保护作用，随着社会的发展，报警器的相当，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 ，检测电路由电阻、非门、开关组成，LED指示电路由发光二极管、电阻组成，触发控制电路由与非门、电阻、二极管，音频振荡器由与非门、电阻、电容组成，音频放大输出电路由三极管、电阻、扬声器组成 。 ABSTRACT The analog electronic technology course design is a disconnected alarm, can simultaneously on multiple sites of anti-theft monitoring, once a cordon was broken, the alarm will immediately send out alarm sound, at the same time indicating theft happens place. The preservation of property plays a good protective effect, along with the development of society, the usefulness of considerable alarm, a cheap beautiful alarm certainly was the favorite of consumers, the technology is more advanced, people life is improved in a certain extent, is beneficial to the stability and prosperity of our society. The curriculum design circuit comprises a detection circuit, LED circuit, a triggering control circuit, an audio oscillator and the output audio amplification circuit, detecting circuit is composed of resistors, gate, switch, LED indicating circuit is composed of light emitting diodes, resistors, trigger control circuit is composed of a NAND gate, resistance, diode, an audio oscillator is composed of NAND gate, resistor, capacitor, an audio amplifying output circuit is composed of a triode, a resistor, a loudspeaker.
