摘　　要：随着电子技术的飞速发展,报警系统已从原来的简单化、局部化向智能化、集成化发展。本文重点阐述了以80C52单片机为基础的火灾报警系统,采用数字温度传感器DS18B20采集温度信号,由四位数码管显示当前温度,同时由16*16LED点阵显示当前情况,低于报警门限显示"正常",高出则显示"火警!"。With the quick development of electronic technology,alarm system has changed from simplication and localization to intelligence and integration. This paper mostly introduces the guard and alarm system based on MCU,which collects the signal of temperature with temperature sensor called DS18B20. The system shows the current temperature with four nixie tube. What＇s more,the 16＊ 16 LED display screen shows＂normal＂when the current temperature is below the alarm threshold,while shows＂fire alarm＂on the opposite situation.
