基于无线传感器网络的鱼塘水质监测系统

本文运用回归和收敛模型对全国，东部，中部，西部污染物排放强度的差异和收敛性进行了实证分析.研究结果表明：我国各地区的污染物排放强度在不同程度上都有所下降，其中以东部下降幅度最大，西部次之，中部最小；经济增长对污染物排放强度的降低起到积极作用，第二产业占GDP比重对污染物排放强度起到正相关作用；全国，东部，中部，和西部地区都不存在绝对β收敛现象，但均存在条件收敛，且中部收敛速度最快，东部收敛速度最慢.

Fishpond Water Quality Monitoring System Based on WSN

Demand for the traditional water quality monitoring system in the water quality parameters on-line monitoring,early warning capability,the lack of data accuracy and stability,comprehensive use of wireless sensor network,GPRS wireless communication,GSM SMS technology and the method,such as building a water quality remote real-time monitoring system.The characteristics of the system is warning in time,rapid response,visualization query and strong extensibility.
