PAGE \* MERGEFORMAT V基于单片机的室内环境检控系统设计与实现摘 要目前人们对室外污染的认识和重视程度有了很大的提高，对室外空气相关的健康问题以及提高空气质量的提高有了很好的了解。但对室内污染的关注程度远远不够，据调查资料显示室内的空气污染比室外大气的污染更为严重，显而易见人们长期处在有污染的室内患病几率将远远高于室外污染。因此加强人们对室内环境的关注迫在眉睫。本系统将很好的检控室内空气及时提醒人们做出相应的处理，为我们的生活增添一份保障。本系统以STM32为空气质量检控的控制单元，根据室内环境综合考虑系统分为两部分，即信息采集处理和报警处理部分。信息采集部分通过DHT11采集室内的温湿度情况，MQ-2采集空气中有害气体的浓度，有害气体包括液化气、丁烷、丙烷、甲烷、酒精、氢气、烟雾等。将采集到的信息逐一在诺基亚5110屏上显示。当室内空气出现问题则跳入报警部分，报警情况将把室内的所有情况通过无线通讯（GSM）发送到手机端，提醒人们及时进行处理。本系统设计主要考虑简单智能化。本系统传感器不需要人为干涉自动处理信息，只需要根据自己的需求设定报警信息，本系统就会根据设定值及时提醒人们室内状况，通过GSM把信息传送到手机上。这样可以及时的获得我们生活空间的情况，大大的降低了人们负担。关键词：单片机、无线通讯、空气质量传感器大连东软信息学院毕业设计（论文） AbstractMicrocontroller-based indoor environment Prosecution System Design and ImplementationAbstractAt present, our understanding of outdoor air pollution and the degree of importance has been greatly improved, with good understanding of outdoor air related health problems and improve air quality. But the degree of attention to indoor pollution is far from enough, according to the survey data show that the indoor air pollution is more serious than outdoor air pollution, obviously people has long been polluted indoor risk will be much higher than outdoor pollution. Therefore, to strengthen the attention to the indoor environment of the imminent. The system will be very good control of indoor air to remind people to make the appropriate treatment, add a guarantee for our life.This system STM32 air quality control unit of prosecution, according to the indoor environment considering the system is divided into two parts, namely, information acquisition and processing and alarm processing section. Information collected in part through the acquisition DHT11 indoor temperature and humidity conditions, MQ-2 capture airborne concentrations of harmful gases, toxic gases, including liquefied petroleum gas, butane, propane, methane, alcohol, hydrogen, smoke, etc.. The information collected is displayed on each screen of Nokia 5110. When the indoor
