基于嵌入式智能家居防火防盗智能 GSM 短信报警系统 Intelligent GSM SMS alarm system based on embedded smart home fire and anti-theft内容摘要伴随经济发展带来的高生活质量，绝大部分民对自身财产和家居安全的注重程度越来越高，希望用先进的技术更用科学可靠的保护自身财产和家居安全，智能家居防警器系统可以将被盗被劫及火灾等损失降到最低，更好的解决突发事件。本课题所研究的智能家居防警器采用 STC89C52 作为主控芯片来控制其他电路，结合外部的气体传感器 MQ-2、红外人体热释电传感器、DS18B20温度传感器来实现外围环境的感知，以及利用 ADC0832 模数转换器、GSM 模块短信、声光报警电路实现内部信息和外部信息的交互。最后用 C 语言编写的控制程序与各模块相结合完成对环境烟雾、温度以及红外的敏锐感知来此实现火灾报警、智能化提示。关键词：GSM 气体传感器 MQ-2 单片机 智能控制AbstractWith the high quality of life brought about by economic development, the vast majority of people pay more and more attention to their own property and home security. They hope to use advanced technology to protect their own property and home security more scientifically and reliably. Smart home alarms The system can minimize losses such as theft, robbery and fire, and better solve emergencies.The smart home alarm device studied in this topic uses STC89C52 as the main control chip to control other circuits, combined with external gas sensor MQ-2, infrared human pyroelectric sensor, DS18B20 temperature sensor to realize the perception of the peripheral environment, and the use of ADC0832 A / D converter, GSM module short message, sound and light alarm circuit realize the interaction of internal information and external information. Finally, the control program written in C language is combined with each module to complete the sensitive perception of environmental smoke, temperature and infrared to realize fire alarm and intelligent prompt..Key wo...
