摘　　要：为实现室内空气质量的智能感知与实时净化,设计了基于物联网的室内空气质量智能感知与净化系统。该系统采用物联网三层体系结构作为整体框架,包括室内环境感知层、网络传输层和应用服务层。系统以STM32为内核微控制器,采用嵌入式实时操作系统为软件平台,设计五层空气过滤网,实现甲醛、PM2.5、TVOC以及温湿度等室内空气质量参数的实时采集,实现手机APP软件远程的监测与控制,建立室内空气质量的评价标准。通过24 h的测试运行,系统运行稳定,实验室内的空气质量得到明显改善,净化效果显著。结果表明,该系统能够对室内空气进行智能感知与净化,并且对空气质量做出客观评价,为室内空气质量的调控提供可靠依据,具有较高的使用价值。To realize the intelligent perce on and real-time purification of indoor air quality, anintelligent indoor air quality perception and purification system was designed based on intemet of things. The overall structure of the system was composed of three of internet of things including the intellisense layer of indoor environment, the network transmission layer and the application service layer. STM32 was taken as the core mieroeontroller in the system. The embed ded realtime operation system was adopted as the software platform. Five layers of air filter network were designed. The real time collection of indoor air quality was realized, such as PM2.5, formaldehyde, TVOC, temperature and humidity. Themo bile APP software of remote monitoring and control was realized. And the evaluation standard of indoor air quality was established. Through the test run of 24 hours, the system ran stably, the air quality in the laboratory the purification effect was remarkable. The results show indoor air, make an objective evaluation of air quality, a high value of use that the system can make intelligent provide a reliable basis for the control was obviously improved, and perception and purification of of indoor air quality, and has
