基于LoRa技术的云平台楼宇火警监测系统设计

Design of cloud platform building fire monitoring system based on LoRa technology

为了解决传统楼宇火警监测系统布线复杂、传输距离短、智能化程度低等问题,结合物联网技术,设计一种基于Lo-Ra技术的云平台楼宇火警监测系统。该系统利用LoRa技术构建无线传感网络,实现监测信息的远距离传输,包含一个汇聚节点和多个终端节点。终端节点通过多种传感器对环境信息进行监测,汇聚节点接收所有终端节点的数据,并经由EC204G通信模块上传至云平台。系统测试结果表明,该云平台能够实时准确地展示环境数据,异常时终端节点和云端均能及时告警,具有覆盖范围广、功耗低、成本低以及部署方便等优点。

A LoRa-based cloud platform building fire monitoring system is designed in combination with the Internet of Things technology,proposed to solve the problems of complicated layout and wiring,short transmission distance,and low intelligence of traditional building fire monitoring system.The LoRa technology is used in the system to build a wireless sensor network,realizing the long-distance transmission of monitoring information and including terminal nodes and converge node.Terminal nodes monitor environmental information through a variety of sensors.The converge node can be used to receive data from all the terminal nodes,and upload to cloud platform by EC20 module.The test results show that the system can accurately display the environment data in the building in real time,and when an abnormal situation occurs,both terminal node and cloud can alert in time.The system has the advantages of wide coverage,low power consumption,low cost,easy deployment and so on,which has a wide application prospect.
