摘　　要：针对用电器电流过大导致短路而造成的火灾突发状况,本设计是一款基于单片机的智能防火报警装置。装置以STC89C51单片机为主控制器,采用DS18B20数字温度传感器实时测量插座温度,并配合数码管显示实测温度值。通过实测温度值与温度阈值的比较,装置可实现声光报警和排查断电功能。实验结果表明:当实测温度超过低温度阈值时,装置产生报警功能;当实测温度超过高温度阈值时,实现用电器的断电处理,该装置对火灾预警具有一定功效。To address the fire emergency caused by the short circuit with excessive electric current,an intelligent fire alarm device based on Micro programmed Control Unit(MCU)is designed in this paper.The MCU STC89C51 is taken as a core controller.A digital temperature sensor DS18B20 is adopted to measure the temperature of the socket in real time,and the temperature is displayed on LED.By comparing the measured temperature value with the temperature threshold,the device can realize the functions of soundlight alarm and the power off check.The experimental results show that the sound-light alarm is generated when the measured temperature is higher than the low temperature threshold,and the device is power off when the measured temperature exceeds the high temperature threshold.The device has some effect on the fire emergency alarm.
