[摘要]本课题设计了一个单片微机区域报警系统的执行机构——声光报警电路。国标规定，火灾区域报警系统进行火灾报警和故障报警时，设有指示灯显示，且报警音响电路必须发出两种不同的声信号以示区别。根据这一要求，本电路设计的音响报警电路采用一个扬声器，在发生火灾或故障的情况下分别发出不同的声信号，同时设有消音键。报警时，基于单片微机控制区域报警系统声光报警电路接收单片机控制器的相关警报电信号，最终将警报电信号用指示灯光信号和扬声器声信号的形式显示出来，完成报警功能。设计相应的振荡电路产生不同频率的脉冲电信号，并通过逻辑门电路组合功能，使扬声器在报警时发出不同频率的声信号。采用D触发器作为系统的清零机构，起到报警后的消音功能。本文将从电路的功能设计要求，电路设计原理与电路各部分的分析以及电路的搭接和调试对本课题的内容进行介绍，最后得出相应的结论。
[Abstract] the subject of a design microcomputer regional warning system executing agencies -- sound and light alarm circuit. GB, the fire alarm system for the regional fire alarm and fault alarm, with light, and audio alarm circuit must send two different signals to show distinction. In response to this request, the circuit design of the audio alarm circuit using a loudspeaker. in the event of fire or failure of the issued under different acoustic signals, while bond with silencers. Alarm, Based on the single-chip microcomputer control regional warning system sound and light alarm circuit receiving MCU Controller of alarm signals, final warning signals using optical signal light and loudspeaker signal is displayed in the form of complete alarm function. Design corresponding oscillation circuit different frequency pulse signals, and through logic gate circuit assembly function make loudspeakers issued the warning at different frequency signal. D flip-flop used as a system reset, the
