基于WSN的水产养殖环境监测系统设计

Design of Aquaculture Monitoring System based on Wireless Sensor Network

摘要:

针对传统水产养殖过程中对水质监测的实时性差,测量精度低等问题,设计基于无线传感器网络的水产养殖环境监测系统。系统利用ZigBee无线通信技术组建传感器网络,采用混合网拓扑结构,通过对传感器节点硬件和软件的设计,完成水产养殖池中的溶解氧含量、PH值、温度等重要养殖指标的实时测量。水质数据汇聚到中心节点后传送给主控制器,并通过GPRS上传至云端保存。另外,针对云存储的安全问题,利用同态加密对上传到云端的数据进行加密,在不破坏云计算能力的前提下保护了用户的隐私数据。

Abstract:

Water quality parameters monitoring in the traditional aquaculture process has the disadvantages of poor real-time performance and poor measurement accuracy. To solve the problems, an aquaculture environmental monitoring system based on wireless sensor network(WSN) is designed. ZigBee wireless communication technology is used to build a sensor network with hybrid topology. Through the design of hardware and software, this system implements the real-time monitoring of water quality parameters, such as dissolved oxygen, pH and water temperature. Water quality parameters are collected to central node, then sent to the main controller, and uploaded to the cloud by GPRS. Furthermore, homomorphic encryption is applied in cloud database to protects users" privacy without disrupting the ability of cloud computing.
