摘　　要：为了能实时、高效地对大气污染物违规排放的监控,提出了一种基于LoRa的无线多参数环境监测系统。利用STM32F103内置基于DMA功能的ADC采集6路电化学传感器的气体浓度数据;利用串口功能实现GPS定位数据、PM2.5/PM10颗粒物浓度数据和温湿度等参数的处理;通过LoRa无线模块,将采集的数据传输至LoRa网关并在手持式终端上显示。测试结果表明,监测系统可以远程实时监测6种气体浓度、PM2.5/PM10颗粒物浓度及行程轨迹等参数,且误差在允许的范围内;结合无人机、无人车等载体平台使用,具有监测范围广、成本低、机动性强等优点,具有广阔的应用前景。In order to monitor the illegal emission of atmospheric pollutants in real time and efficiently,a wireless multiparameter environmental monitoring system based on LoRa is proposed.The ADC and the serial port with DMA function inside of the STM32 F103 is used to collecte the data of 6 electrochemical gas sensors,GPS location data,PM2.5/PM10 particle concentration data,the temperature and humidity.The collected data is transmitted to the LoRa gateway through the LoRa wireless module and displayed on the terminal.Test results show that the system can monitor 6 kinds of gas concentration,PM2.5/PM10 particle concentration,temperature and humidity and travel path in real time,and the error is within the allowable range.The system combined with UAV or unmanned vehicle has the advantages of wide monitoring range,low cost and high mobility,leading to a broad vision of application.
