基于WSN的水产养殖环境参数监测系统设计

摘要

针对国内水产养殖技术的自动化水平较低,以及同类监测产品价格较高的现状,提出一种基于无线传感器网络(WSN)的水产养殖环境参数智能监测系统.通过在监测区域部署网络节点,以微处理器为核心控制单元的无线传感器网络实时采集水体温度.溶氧量浓度和pH值等环境数据,并进行处理,将其发送到接收终端,由中央监测计算机对数据进行存储和显示,实时监测养殖环境参数变化.将其应用于实际的养殖现场,试点结果显示,该系统性能稳定,数据传输可靠性高,使用灵活,性价比高,监控准确,增产明显.%To solve the problems such as low automation technology and high price of monitoring system in aquiculture of our country, a kind of environmental factors intelligent monitoring system based on WSN was designed. By placing network nodes in monitoring area, the collection part based on single chip microcomputer digitalized the signal from the sensor of temperature, dissolved oxygen and pH, and sent it out using wireless digital transmission technology. At the reception part, the data is received, saved and displayed by central monitoring computer. Thus environmental factors of the aquieulture was monitored in real time. The system was applied in practical aquiculture field. Experimental result indicates that the system is quite reliable and suitable, provides a practicable measures, and is high in theratio of performance to price. It can achieve to monitoring perfectly and improve productivity remarkably.
