摘要
为更好地实现实验室安全管理和改进传统无线实验室安全预警系统组网复杂、传输距离短和高功耗等不足,提出一种基于LoRa的远程分布式实验室安全管理系统。系统以STM32F407微控制器为主控芯片,采用不同传感器对实验室环境数据进行监测,利用LoRa无线通信模块组建数据传输网络。数据传输网络中的汇总节点接收所有监测节点的数据,将数据打包处理后通过GPRS通信网络将数据上传ONENET云平台,在ONENET云平台上对数据进行统计分析。通过测试,系统能够实时、准确监测实验室内现状,运行稳定可靠,满足实验室内环境监测需求,可以针对突发情况进行报警,并进行应急处理。
Laboratory safety data management and traditional wireless laboratory safety early warning system exist lots problems such as complex networking,short transmission distance and high power consumption.In order to solve these problems,an LoRa-based remote distributed laboratory safety management system is proposed.The system uses STM32 F407 microcontroller as the main control chip,uses different sensors to monitor laboratory environmental data,and uses LoRa wireless communication modules to build a data transmission network.The summary node in the data transmission network receives the data of all monitoring nodes,packs the data,and uploads the data to the ONENET cloud platform through the GPRS communication network.The data can be statistically analyzed on the ONENET cloud platform.Through the test,the system can accurately monitor various data in the laboratory in real time,run stably and reliably,meets the environmental monitoring requirements in the laboratory,and can respond to emergencies by alarming and emergency treatment.
