| 摘 要： | 针对现有可变区域范围内空气质量监测机动性差、信息化程度低及管理不便等问题，设计并实现了一种基于NB-IoT的区域空气质量监测系统，系统由多个监测节点、远程监管平台及Android移动终端组成。监测节点采用STM32为微控制器，采集所在位置的空气质量相关参数，并通过NB-IoT通信模块发送至远程监管平台，实现对大区域空气质量的监控与管理，通过下发指定小区域的权限至Android移动终端，可以查看权限范围内的空气质量状况。系统测试表明:测量精度高，数据传输稳定可靠，满足多场景环境下灵活应用的需求。

Design and Implementation of Regional Air Quality Monitoring System Based on NB-IoT |
| |
| Abstract: | In order to solve the problems of poor mobility, low degree of informatization and inconvenient management of air quality monitoring in the existing variable area, a regional air quality monitoring system based on NB-IoT is designed and implemented. The system is composed of multiple monitoring nodes, remote monitoring platform and Android mobile terminal. The monitoring node uses STM32 as the microcontroller to collect the air quality parameters of its location and send them to the remote monitoring platform through the NB-IoT communication module to realize the monitoring and management of air quality in large areas. By issuing the authority of the designated small area to the Android mobile terminal, then the terminal can check the air quality status within the scope of authority. The system test shows that the measurement accuracy is high, the data transmission is stable and reliable, and it meets the needs of flexible application in multi-scene environment. |
