无线空气质量PM2.5测量系统的研究

Study on a wireless PM2.5 measuring system for air quality monitoring

近几年,随着工业化进程的不断加快,中国面临越来越严重的环境问题。基于环境监测的需要,设计了一种集光电检测技术、无线传感网络传输及计算机软件分析于一体的新型PM2.5监测系统,能够很方便地检测环境中漂浮的微小固体颗粒,形成针对PM2.5浓度的监测数据。测试系统可以在每天上午6时至12时,每小时整点测量一次数据,直接得到空气质量PM2.5值,当数值超过300μg/m^3,系统会发出报警。在不同地点设置该系统,通过不同时间段的测量,即可形成关于PM2.5值的大数据系统,最后可对环境空气质量状况完成综合分析。本系统具有小型化、简便化、成本低廉、操作方便的优点,为其生活实用化提供了有利条件。

With the accelerating process of Chinese industrialization, serious environmental problems are faced in recent years. Based on the requirements of environmental monitoring, a PM2.5 monitoring system with photoelectric detection technology, wireless sensor network transmission and computer software analysis in integral whole is designed in this paper, which can easily detect tiny solid particles floating in air and get the data about PM2.5. The system can complete detection on the hour from 6 a.m. to 12 a.m., and give alarms when the measurements are in excess of 300μg/ m^3. With the data measured at different times and locations a big data system about PM2.5 can be built, and comprehensive analyses of ambient air quality can be completed. The system has the advantages of small size,simple structure, low cost and convenient operation.
