基于LoRaWAN 的多参数城市环境监测系统的设计与实现

Design and Implementation of Multi Parameter Urban Environmental Monitoring System Based on LoRaWAN

针对城市生态环境监测与环境数据信息管理问题,本文提出了一种基于LoRaWAN的多参数城市环境监测系统。系统包括上位机监控管理中心和下位机环境数据采集和传输设备两部分。下位机的环境数据采集设备采用多传感器测量采集环境参数,并将采集结果通过LoRa(Long Range Radio,远距离无线电)无线网络上传至上位机监控管理中心进行监控和管理。当采集到的数据超出设定阈值时,系统能够进行预警和告警。试验结果表明,系统监测范围广、监测效率高,能够智能、实时地对城市环境进行监控,具有一定的实用价值。

Aiming at the problems of urban ecological environment monitoring and environmental data information management,this paper proposes a multi-parameter urban environment monitoring system based on LoRaWAN.The system includes two parts:the upper computer monitoring management center and the lower computer environment data acquisition and transmission equipment.The environmental data acquisition equipment of the lower computer adopts multi-sensor to measure the environmental parameters,and upload the acquisition results to the upper computer monitoring management center through LoRa wireless network for monitoring and management.When the collected data exceeds the set threshold,the system can give early warning.The test result shows that the system has a wide range of monitoring,high monitoring efficiency,which can intelligently monitor the urban environment in real time and has a certain practical value.
