基于单片机的天然气报警系统设计

Design of Natural Gas Alarm Based on Single Chip Microcomputer

为了有效减少我国家庭火灾事故的发生,提高人民家庭的安全水平,给人们带来更为舒适放心的生活环境,设想如果可以研发结构简单、经济实用的家庭烟雾报警器实现天然气报警系统的智能化,那就可以大幅度地减少家庭火灾事故发生的概率。本文根据单片机原理与传感器理论,提出一种基于单片机的天然气报警系统设计,它以单片机为控制核心,通过分析气敏及温度传感器模块传递回来的数据以达到蜂鸣器报警的目的。气敏传感器及温度传感器检验天然气的易实现性、高精度性以及自适应理论的应用,都使得该报警器可以更精确的检测并报警。通过理论研究与仿真演示,证明此报警器可以很好的完成检测及报警目的,但要达到实际应用还需要进一步的探讨与研究。

In order to effectively reduce the occurrence of domestic fire accidents in our country, improve the safety level of people’s families, and bring people a more comfortable and comfortable living environment, it is assumed that if a simple, economical and practical domestic smoke alarm can be developed to realize the intellectualization of the natural gas alarm system, the probability of domestic fire accidents can be greatly reduced. According to the principle of single chip microcomputer and sensor theory, this paper puts forward a design of natural gas alarm system based on single chip microcomputer. It takes single chip microcomputer as the control core, and achieves the goal of buzzer alarm by analyzing the data transmitted back by gas sensor and temperature sensor modules. The easy realization, high precision and the application of adaptive theory of gas sensor and temperature sensor to test natural gas make the alarm more accurate to detect and alarm. Through theoretical research and simulation demonstration, it is proved that this alarm can achieve the purpose of detection and alarm well, but further discussion and research are needed to achieve practical application.
