网格化大气环境在线监测系统设计

Design of gridized atmospheric environment online monitoring system

随着经济的快速发展,我国工业化程度不断提高,污染问题也逐渐显现。空气质量作为衡量大气污染程度的重要指标,越来越受人们重视。目前,人工监测存在人力成本高且效率低等问题,自动化监测站存在设备费用高且覆盖率低等问题,因此,建立网格化的小型在线监测系统显得至关重要。首先阐述了网格化监测的必要性,其次对系统作出总体设计,以STM32系列为处理器,以多种传感器作为数据采集端,通过编写软件程序,实现对相关数据的处理;又设计了物联网云平台,采用无线通信技术将处理后的数据实时传送至云平台,实现了大气环境监测的高效化。

With the rapid development of economy, the degree of industrialization in China has been continuously improved, and the pollution problem has gradually emerged. As an important index to measure the degree of air pollution, air quality has been paid more and more attention.At present, manual monitoring has the problems of high labor cost and low efficiency, and automatic monitoring stations have the problems of high equipment cost and low coverage. Therefore, it is very important to establish a small gridized online monitoring system. Firstly, the necessity of gridized monitoring is described. Secondly, the overall design of the system is made. The STM32 series is used as the processor, and a variety of sensors are used as the data acquisition end. By writing software programs, the processing of relevant data is realized. The cloud platform of the Internet of Things is also designed, and the processed data is transmitted to the cloud platform in real time by using wireless communication technology, which realizes the high efficiency of atmospheric environment monitoring.
