基于单片机的智能家居防火防盗报警系统毕业设计方案

基于单片机智能家居防火防盗报警系统摘要伴随社会不停进步和科学技术、经济进展，大家生活水平得到很大提升，大家愈加重视人身安全，所以也对防火防盗方法提出了新要求。本设计所做智能家居控制系统包含室内信息智能监控功效、输入和实时显示功效、声光报警功效等。本文利用单片机结合传感器技术而开发设计了这一防火防盗报警系统。本设计实行 DYP-ME003 人体红外感应模块、18B20 温度传感器和 MQ_2 烟雾传感器检测信号，然后将信号传送给单片机处理,实现声光报警。该系统经过按键对系统温度和烟雾浓度进行初始化设置，利用 LED 显示模块对系统温度和烟雾浓度进行实时显示。该系统结构简单、性能稳定、使用方便、价格低廉，含有一定有用价值。关键字：防火防盗报警 18B20 MQ_2 DYP-ME003Abstract With society’s progress and development of science and technology, economy, people's living standard has been greatly improved. People pay more attention to personal safety, thus they put forward new requirements for the fire and security measures. In this design ,the intelligent family- house control system includes this function : indoor information intelligent monitoring , the input and real-time display ,sound and light alarm, and so on .The design is a fire and security system, which combines sensor technology with microcontroller. This design adopts the DYP-ME003 human body infrared sensor module,18b20 temperature sensor and MQ_2 smoke sensor to detection signal. These sensor send the signals to microcontroller.The microcontroller process these signal and drive alarm circuit to achieve sound and light alarm .The fir temperature and smoke concentration are initialized in this system.,and are displayed in the LED display .The system has the advantages of simple structure ,stable performance ,conventional operation ,low price ,and has a certain practical value .
