摘要
为提高室内空气质量监测的智能化水平,本文设计了一种基于嵌入式技术、QQ物联平台以及物联网架构,建立了智能室内空气监测系统。系统采用分层设计,分为感知层、传输层和应用层3层架构。感知层以STM32为核心控制芯片,搭建各类空气传感器,实现数据采集;传输层采用QQ物联平台,打造智能硬件,将数据传输到QQ云端;应用层以手机QQ软件为载体,从云端下载数据,显示各种空气质量状况。经过测试,该系统可以采集所设置的空气质量数据,并且在用户QQ端显示当前室内空气质量状态,数据误差在可允许范围之内。该系统方便可靠,扩展性强,可满足用户对室内空气质量监测的要求。
Aiming at the shorting of current air monitoring system, such as their unity, poor practicality, and high price, in order to improve the intelligence level of indoor air quality monitoring, the smart indoor air moni toting system is proposed which is based on embedded technology, QQ lOT platform and loT. The system uses hierarchical design concept which consists of perception layer, Transmission layer and application layer. The perception layer uses STM32 as the core control chip, building various types of air sensors to realize data acqui sition. Transmission layer uses QQ platform to create intelligent hardware and sends the data to the QQ cloud. The application layer applies mobile QQ software as a carrier which can download data from the cloud to display a variety of air quality conditions. After testing, the system can collect the set data of air quality, and the cur rent indoor air quality status can be displayed in the user QQ side. Besides, data error is within the allowable range. The system is convenient, reliable and scalable which can meet the user's indoor air quality monitoring requirements.
