基于无线传感网络的水污染预警监测系统设计

Design of Water Pollution Early Warning Monitoring System Based on Wireless Sensor Network

针对传统水污染监测技术的不足,设计了一种集成GPS全球定位、GPRS网络数据传输、ZigBee无线传感网络、超声波流量检测、压力检测和污染物快速检测等多项技术于一体的预警监测系统。该系统从硬件和功能结构上分为三部分,分别是数据采集节点、数据汇聚节点和远端监控中心,能够实现传感数据自动采集、监测地点自动定位、无线传感网络数据转发和GPRS/4G数据远传功能。系统不仅可以实现传统的"定点""定位"测量,而且能实现区域化、网络化的预警监测,同时还能有效地防止污水排放管理中的漏洞。

In view of the shortcomings of traditional water pollution monitoring technology,the early warning and monitoring system is designed with an integrated GPS global positioning,GPRS network data transmission,ZigBee wireless sensor network,ultrasonic flow detection,pressure detection and rapid detection of pollutants.The system is divided into three parts in hardware and function structure,namely data acquisition node,data gathering node and remote monitoring center which will realize such functions as automatic acquisition of sensing data,automatic location of monitoring sites,wireless sensor network data forwarding and GPRS/4G data remote transmission.It can not only realize the traditional fixed point and positioning survey,but also realize the regionalization and network early warning and monitoring,at the same time,it can effectively prevent the loopholes in the sewage discharge management.
