基于Lora的水质检测系统设计

Design of Water Quality Detection System Based on Lora

针对具有多点远距采集特点的现代水质检测系统存在组网复杂、成本高且功耗高的问题,设计了一种基于Lora技术的新型智能水质检测管理系统,采用Lora低功耗,超远距离通信的特点,能对水质检测区的各水温,溶氧量,PH值进行实时观测记录且可通过设置阈值或人工控制对水泵机进行远程操作。该设计以SX1276模块为核心,介绍了网关和节点的软硬件设计以及组网结构。实验结果表明:该系统具有组网简单,低功耗,可远距离通信等特点,可以实时检测水质信息,并完成下行控制,为水质检测的管理提供了一个较好的解决方案。

In view of the problems of complex network, high cost and high power consumption in modern water quality detection system with multi point distance acquisition, a new intelligent water quality detection management system based on Lora technology is designed. This system using Lora low power consumption, and super distance communication features. Which can be used of recording such as water temperature, dissolved oxygen and pH values of the whole breeding area in real time and it can operate remotely through the threshold or manual control. The design takes the SX1276 module as the core. and introduces the software and hardware design of the gateway and node and the network structure. The experimental results show that the system has the characteristics of simple network, low power consumption and super distance communication. It can detect water information in real time and complete downlink control, which provides a better solution for the management of water quality detection.
