摘要：小区防盗防火系统是一款新型的智能报警装备，它可以在灾情出现时，及时发出预警，及时通知小区工作人员和用户。本文中设计的防盗防火报警系统是通过探测器来接受外界的信号，并将外界信号进过处理后转换成电信号，并将之传到AT89S52来继续处理收到的电信号，其中单片机中有编写好的汇编语言。当它满足触发要求后，AT89S52会将处理后的信号传给两个蜂鸣器和LED灯。其中把一个蜂鸣器放置在用户家中，另一个放置在小区的保安服务中心。LED灯的放置如同蜂鸣器。一旦检测到灾情，蜂鸣器会发出警鸣声。同时，LED由暗变亮。从而达到警示人们的目的。43439

Community security fire prevention system design
Abstract: residential security fire prevention system is a new type of intelligent alarm equipment, it can be in the presence of the situation, timely warning, timely notify the residential staff and users. The security fire alarm system design in this article is through the signal detectors to accept the outside world, and the external signal into converted to electrical signals, after processing and upload the AT89S52 devices will continue to receive signals, write good assembly language of single chip microcomputer. When it meets the demand of trigger, AT89S52 devices will be processed signals to two buzzer and LED lights. Which placed a buzzer on the user's home, another place in the area of security service center. The placement of the LED lamp as a buzzer. Once detected disaster, buzzer will send police siren. At the same time, LED by the dim light. So as to achieve the purpose of warning people.
Key words: security fire prevention; AT89S52 devices; The LED; Buzzer. Assembly language
