教室是学生长期学习的地方,其内部空气质量直接关系到师生的身体健康.传统的空气质量监测方法是使用手持设备不定期到每个教室进行人工测量,不仅效率低下,且不能实现实时监测.部分智能的联网空气监测系统采用ZigBee协议组网,部署难度大,成本高,不易于推广.为解决此问题,提出一种基于LoRa协议组网的智慧校园空气质量实时监测系统.该系统通过在教室部署空气质量传感器,经长距离LoRa无线网络将监测到的数据实时上报到网关,网关对数据进行实时分析和预警,显著提升教室空气质量监测的准确性和实时性.实验结果表明,本系统部署传输距离远、实施简单、传输可靠,实现了对教室空气质量的实时监测及预警.
Design of Air Quality Monitoring System for Smart Campus Based on LoRa
The classroom is a place where students spend a considerable amount of time learning,and its indoor air quality is directly related to the physical health of teachers and students.The traditional method of air quality monitoring involves the use of handheld devices to conduct manual measurements in each classroom irregularly,which is not only inefficient but also fails to achieve real-time monitoring.Some intelligent networked air monitoring systems utilize the ZigBee protocol for networking,but their are difficul-ties in deployment,high costs,and are not conducive to widespread adoption.To address this issue,this article proposes a smart cam-pus air quality real-time monitoring system based on the LoRa protocol for networking.This system deploys air quality sensors in classrooms,utilizing the long-range LoRa wireless network to report the monitored data to the gateway in real-time.The gateway then conducts real-time analysis and alerts,significantly improving the accuracy and timeliness of classroom air quality monitoring.Experimental results demonstrate that this system has the advantages of long transmission distance,simple implementation,and reli-able transmission,enabling real-time monitoring and early warning of classroom air quality.
