摘要
河道水质监测智能化是智慧城市建设的重要组成部分。针对河道水质监测系统中节点分布广,数据传输距离远、干扰较大以及供电困难等问题,设计了基于LoRa技术的多参数水质监测节点。该节点采用太阳能和锂电池结合方式供电,提供多路数据采集接口,可外接多个基于Modbus通信协议的工业级水质传感器,并为满足长期稳定工作需求,在硬件和软件上对节点进行低功耗设计。最后通过验证,表明该节点可以有效在线监测河道水质参数,实现水质远程监测。
Intelligent monitoring of river water quality is an important part of smart city construction. To deal with the problems of wide distribution of monitoring nodes,long distance of data transmission,large transmission interference and difficult power supply in river water quality monitoring system,a multi-parameter water quality monitoring node based on LoRa technology is designed. The node is powered by a combination of solar energy and lithium battery,and provides multi-channel data acquisition interface. It can externally connect multiple industrial-grade water quality sensors based on Modbus communication protocol. And in order to meet the long-term stable work requirements,the nodes are designed with low power consumption in hardware and software. Finally,the verification shows that the node can effectively monitor the water quality parameters of the river online and realize remote monitoring of water quality.
