基于STM32的燃气报警器设计(开题报告,论文12600字)
摘 要
随着社会的不断进步，各种各样的能源开始被人们广泛利用。以前靠木材，煤炭来生火做饭的方式被煤气所取代，但是煤气主要成分是剧毒一氧化碳。近些年随着中俄战略天然气能源引进合同的签订，我国开始大范围推广更安全更天然气。天然气的主要成分是甲烷，是一种易燃易爆的气体，随天然气推广，越来越多的家庭开始使用天然气。天然气的主要成分甲烷是一种易燃易爆气体，当空气中甲烷泄漏浓度达到5%～15%时，遇到明火就会爆炸。因此，解决天然气的安全使用问题刻不容缓。现如今科技的不断发展，单片机技术已经相当成熟，已广泛应用到各种控制类型的一起上面，它成本低，体积小，易于开发学习。传感器技术也在不断的进步，其精度，便携度，可靠性，获取信息量越来越高，成本也越来越低廉。以传感器加单片机为基础的各种探测仪器层出不穷，早已从工业需求走进了寻常百姓家。

The Design of the RLC Measuring Instrument
Abstract
With the constant progress of the society, has been widely used all kinds of energy. Used to rely on wood, coal for the fire replaced by gas cooking way, but the gas main component is highly toxic carbon monoxide. In recent years as the China-Russia strategic natural gas energy import contracts signed, widely promoted to safer and more natural gas in our country. The main composition of natural gas is methane, it is a kind of inflammable and explosive gas, with natural gas, more and more families start to use natural gas. The main components of the gas methane are a flammable and explosive gas, when the concentration of methane in the air leakage of 5% ~ 15%, the flame would explode. Therefore, it is very urgent to solve the problem of the safe usage of natural gas. Today, the continuous development of science and technology, microcontroller technology already quite mature, has been widely applied to various types of control together, its low cost, small volume, easy to development and learning. Sensor technology is also in constant progress, its precision, portable, reliability, access to information is more and more high, and the cost is becoming more and lower. On the basis of the sensor and MCU of various instruments emerge in endlessly, already entered the ordinary people from the industrial demand。
