Design of water quality monitoring system based on WSN and ZigBee

摘要

In the thesis, based on actual demand, a set of water quality monitoring system on the basis of wireless sensor network, ZigBee technology and general packet radio services (GPRS) technology is designed to realise a large scale of real-time water quality monitoring. Wireless sensor network is applied to city macrozone water quality monitoring system, in the meantime, wireless transmission technologies such as ZigBee and GPRS are combined to realise collection and transmission of water quality data, and technologies such as sleep mode management, automatic alarm of exceeding water area, self-adaptively high-speed collection, preferred transmission and network cluster node topology control optimisation are adopted to improve energy utilisation efficiency of the system, which reduces the cost of system maintenance and use and meets with actual application demands. System networking and deployment are convenient comparatively with great expandability and application prospects.
