摘要:煤气的广泛使用给居民生活带来了诸多便利,提高了生活质量效率,还减少了环境污染。但是,煤气具有一定的危险性,一旦发生不同程度的泄漏,若处理不及时,就可能引发中毒,甚至是爆炸,给广大群众的人身与财产安全带来威胁。面对煤气泄漏而带来的各种安全隐患,如何对其实现统一化智能控制和预警成了一个急需解决的问题。本文设计了一种新型煤气浓度检测器,其使用基于GSM 作为通讯模块,以STC89C52单片机为主控芯片,配合使用MQ-2气体传感器和ADC0809芯片,采集煤气泄漏的信息。该检测器实现了对煤气浓度的识别以及智能化控制并能发出危险报警,使用户与智能设备的沟通更加方便,具有一定的使用价值。

Abstract: The widespread use of the gas brings human beings lots of convenience, which not only improves the quality and efficiency of life, but also reduces the environment pollution. However, gas has a certain risk, once the different degree of leakage occurred, if not handled in time,it may cause a toxication , even an explosion, threating the safety of people and property. Due to the security risks caused by gas leakage, it has been a problem how to realize the unified intelligent control and early warning of the leakage. In this paper, the design of a new type of gas concentration detector,which is based on GSM as the communication module, and takes STC89C52 Microcontroller as the main controlling chip. With the use of MQ-2 gas sensor and ADC0809 chip ,the detecter can collect the information of gas leakage. The detector realizes the identification and intelligent control of gas concentration and it can send alarm, so its more convenient and valuable for the users to communicate with intelligent equipment .

近年来,液化气、燃气等可燃性气体在家庭中的使用需求正日渐攀升,但是这些气体易燃、易爆,使得隐患事故频见报导。一旦气体泄漏时不能做到及时发现与处理,就会给家庭甚至邻居带来灾害,甚至将威胁到广大群众的人身与财产安全。针对煤气泄漏而形成的各类的各种安全隐患,家用煤管道气体泄漏报警器即已成为应对煤气泄漏的重要手段。当前,GSM 是应用最为广泛的移动电话标准。全球已有超过200个国家和地区的10余亿人正在使用GSM电话。所有用户可以在签署了"漫游协定"移动电话运营商之间自由无碍地实现漫游。将前述二者加以结合则可看出,基于GSM的煤气浓度检测器正在日常生活中发挥着举足轻重的关键作用,因而已然成为时下具有高度需求和发展价值的研究方向。……
