Design of Fire Detection System Based on Bluetooth Mesh and NB-IoT

针对目前建筑安全管理中的火灾检测存在的问题,本文提出了一种基于蓝牙Mesh与NB-IoT技术的火灾检测系统设计。该系统主要包括终端节点、网关节点和云服务器三个部分。终端节点与网关节点组成蓝牙Mesh网络,该网络可以覆盖整个建筑,并确保数据传输的稳定性。终端节点采集当前环境的温湿度和烟雾浓度,网关节点接收来自终端节点的数据,采用NB-IoT窄带物联网技术,利用MQTT协议与云服务器进行对接,将数据上传到云端。云服务器实时存储和处理数据,并在检测到火灾时向相关人员发送警报消息。最终实现一个低功耗、广泛覆盖和高可靠性的火灾检测系统。

This article proposes a fire detection system design based on Bluetooth Mesh and NB-IoT technology to address the existing problems in fire detection in current building safety management.The system mainly consists of three parts: terminal nodes, gateway nodes, and cloud servers. The terminal nodes and gateway nodes form a Bluetooth Mesh network, which can cover the entire building and ensure stable data transmission. The terminal nodes collect the temperature, humidity, and smoke concentration of the current environment, and the gateway nodes receive data from the terminal nodes. Using NB-IoT narrowband IoT technology and the MQTT protocol, the gateway nodes connect to the cloud server to upload data to the cloud. The cloud server stores and processes data in real-time and sends alarm messages to relevant personnel when a fire is detected. Ultimately, this system realizes a low-power, widely covered, and highly reliable fire detection system.
