摘　　要：在危急情况发生时,报警器对人们有警醒作用。随着人们安全意识的增强,多用途的报警器已成为研究的重点。以AT89S52单片机为主系统,由电源电路、键盘电路、LED灯电路和喇叭电路等构成整体硬件系统。以C语言作为编程语言,软件部分设计分别包括系统I/O口分配设计、喇叭音调设计等,实现6种危险情况的报警,当某一种险情出现时,对应的1种音频响起,同时对应1种颜色的LED灯亮起,从而起到多音频报警作用。Alarms put people on alert in critical circumstances. With the enhancement of people＇s safety awareness,multipurpose alarms have become a key research subject. Using AT89 S52 single-chip microcomputer as the main system,the hardware system is composed of the power circuit,keyboard circuit,LED circuit and horn circuit. Using C language as programming language,the design of the software part includes design of distribution of system I/O and design of the tones of the horn to realize alarm in 6 critical circumstances. When a certain dangerous situation happens,the corresponding audio will be given and the LED of the corresponding color will light up,thus performing the function of multiple audio alarm.
