摘要
煤气已成为人们生活中必不可少的能源了,煤气泄漏时有发生,煤气泄漏使人中毒,可能会发生爆炸,给人们的人身安全和财产安全带来了很多隐患,所以防止煤气泄漏检测装置已成为人们迫切的需要,为此开发煤气泄漏报警检测装置是非常必要的。
家庭智能化的定义,在国际上至今尚无一致的理念,在现代化的城乡住宅小区中和采用微型计算机、自控装置、通信等技术,建立一个物业管理中心与安全防护监控系统。而且国家建设部规定,目前住宅小区应实现六项智能化要求,其中就包括实行安全防范系统自动化监控管理、防盗报警系统应安装红外或微波与煤气泄漏报警器等各种类型报警装置,基于此项规定,煤气泄漏检测报警装置实现智能化势在必行。
本系统主要针对传统煤气,液化气的泄漏进行检测,报警。本系统有如下特点:用单片机实现控制,电路简单、价格便宜、可靠性好。采用增强型51单片机,MQ-5气体传感器,煤气泄漏时会发出灯光和声音的报警,因此本系统可作为智能家居安全防护系统中的一部分。

Abstract
Gas has e essential to people's life energy, gas leakage occur from time to time, gas leak caused may explode, to people's personal safety and property safety brought a lot of hidden dangers, so to prevent gas leakage detection device has e the urgent need, for the development of gas leakage alarm detection device is very necessary.
Definition of smart home and in the world so far there has been no unanimous idea, in the modernization of urban and rural residential and the puter, an automatic control device, communication technology, establish a property management center and security monitoring system. And national regulations of the Ministry of construction, the residential district should realize six intelligence requirements, including the implementation of security management of automation monitoring system, anti-theft alarm system should be an infrared or microwave and gas leakage alarm, such as various types of alarm device, based on this provision, gas leak detection alarm device to realize intelligent is imperative.
This system mainly for the traditional gas, liquefied gas leak detection and alarm. The system has the following features: with single-chip puter control, circuit simple, inexpensive, good reliability. Using the enhanced 51 microcontroller, MQ-5 gas sensor, gas leakage is the alarm and sound, so the system can be used as a
