📦 基于单片机的智能火灾报警器设计 - 免费下载

随着城市化进程的加快和人口的迅速增长,我国火灾发生的次数、频率、造成的损失都不断上升。因此,如何在最短时间内发现火灾并控制灾情,使人民生命、财产损失降到最小就显得尤为重要。该文采用STC89C52单片机为中央控制单元,应用MQ-2型半导体气敏式烟雾传感器和DS18B20数字温度传感器为检测单元,外加4个功能设置按键,4位一体数码管显示屏,设计出的可以对火灾进行实时监控,并可自动报警的智能火灾报警器。

Along with the acceleration of urbanization and the rapid growth of the population, the numbers, frequency, causing losses of fire in our country are rising. Therefore, it is particularly important to find fire and control the disaster in the shortest time and minimize the loss of people's life and property. Singlechip STC89C52 is selected as the central control unit in the paper, where detection unit is composed of a MQ-2 type semiconductor gas sensitive smoke sensor and a DS18B20 digital temperature sensor. Four function setting keys and the four bit digital tube display screen are included in the design. Intelligent fire alarm can be used to real-time monitor fire and automatically alarm.
