一种无线传感器网络的设计与应用

Design and Application of Wireless Sensor Network

针对传统的水质监测手段耗时、步骤复杂和自动化程度低等特点,提出了一种基于无线传感器网络的水质在线自动化监测方案。该方案把携带不同类型传感器的无线传感器网络节点布置于所监测水域,利用ZigBee协议实时采集和传输数据,使用ZigBee/IP网关进行协议转换后,通过以太网把采集数据传输到监控中心,全面提升了监测自动化水平。实验结果表明:该系统功耗低、抗干扰性强、节点体积小,适用于工业现场污水处理中实时连续监测。

Traditional water quality monitoring system has disadvantages such as time-consuming,complicated steps and low degree of automatic.This paper introduced an automated online water quality monitoring system based on wireless sensor network.Wireless sensor network（WSNs）nodes with different types of sensors was placed into the water to be monitored,and ZigBee network was used to collect and transmit data.The collected data was transmitted to ZigBee/IP gateway to convert protocol,and then to the monitoring center via Ethernet.The level of monitoring automation was improved by this system.The experiments prove that the system coming with the features of low-power,high noise immunity and small size.All these features are suitable for real-time and continuous monitoring in the sewage treatment.
