摘要
针对中小型水域环境监测问题,提出了一种基于窄带物联网技术的水上环境监控系统解决方案。系统采用了LoRa通信技术和嵌入式技术,分为三层:移动采集感知层、网络层和应用层,由自主移动智能采集终端装置(含LoRa模块)、网关汇聚节点、服务器及监控终端组成。采集终端装置以MSP430F169和SX1276为核心芯片;网关汇聚节点基于FreeRTOS系统,以STM32F407为核心;服务器使用Apache开发。系统完成了中小型水域的环境监测(水上垃圾、水质信息)及管理,为中小型水域环境管理提供了一个有效的解决途径。
Aiming at problems of environmental monitoring in small&medium-sized water,a solution of water monitoring system based on NB-IOT technology is proposed.The system adopts communication and embedded technology,in which there are three layers:moving acquisition perception layer,network layer and application layer.The system is composed of intelligent acquisition terminal devices(Lora module) moving autonomously,gateway aggregation nodes,server and monitoring terminal.MSP430F169 and SX1276 are core chips in acquisitionterminal devices.Gateway aggregation nodes are designed based on FreeRTOS and STM32F407.Apache is used in server development.The system completes the environmental monitoring (water rubbish,water quality) and management of small&medium-sized water,which provides an effective solution for the environmental management of small&medium-sized water.
