基于无线传感器网络的水产养殖水质监测系统

Monitoring System of Aquaculture Water Quality Based on Wireless Sensor Network

集约化的水产养殖对养殖水体水质有较高的要求,不准确的测量和延迟的数据采集会影响养殖生产的顺利进行。设计了一种基于无线传感器网络的水产养殖水质监测系统,将无线传感器网络与上层应用系统有机结合,在自组网情况下实现了水产养殖相关数据的实时监测。该系统在Cotex-M4 ARM架构下以微处理器STM32F405与无线射频芯片CC2530为核心,对系统底层硬件、底层软件、应用层软件进行了开发。同时,为提高数据的准确性,采用新型支持度函数加权融合算法对系统采集的多传感器数据进行融合。整个系统测量精度高,实时性强、运行稳定,能够较好地满足水产养殖水质监测的要求。

Intensive aquaculture has high demands on the quality of culture water.Inaccurate or delayed water quality monitoring will do harm to the regular fishery production.To solve these problems,this study designed a monitoring system of aquaculture water quality based on wireless sensor network.It combined the wireless sensor network with application system together,and realized the real-time monitoring of aquaculture water quality by using ad-hoc network.Under Cotex-M4 ARM architecture,the monitoring system used microprocessors STM32F405 and wireless RF CC2530 chip as a core.Meanwhile,it developed corresponding underlying hardware,software and application software.In order to enhance the data accuracy,an improved support degree function was applied to fuse multi-sensor data in monitoring system.This system had high measurement accuracy,real-time and stability,which could meet the requirements of aquaculture monitoring.
