Abstract

The invention relates to a water environment monitoring node based on ZigBee wireless technique. The prior technology has long monitoring period and large work intensity, and cannot reflect dynamic variation of water environment. The invention includes an electric power management module, a water quality parameter acquisition module, an MPU module and a ZigBee radio frequency module. The equipment adopts an MSP430F149 MPU, for analyzing and processing water environmental parameter, and controls the operating status of the ZigBee radio frequency module and the water quality parameter acquisition module. The MSP430F149 processor is interconnected to the water quality parameter acquisition module through a 12 bit A / D converter self integrated with the MSP430F149 processor, and is interconnected to the ZigBee radio frequency module through an SPI serial interface, meanwhile also controls a power supply management module to supply power through an analogue switch, so as to achieve the goal of energy-saving. The invention has low cost, and low power consumption; can be arranged in water environment for a long term, execute multiple parameter real time monitoring to the water environment, and complete the high-efficiency transmission of data, thereby having wide applications prospect in the water environment monitoring.

Description

technical field

[0001] The invention relates to a wireless sensor network node device that can be used for water environment monitoring. The device adopts a low-power consumption processor and high-efficiency ZigBee wireless transmission technology, and belongs to the technical field of wireless communication and embedded systems. Background technique

[0002] Water environment monitoring is an important means of water resources management and protection. In my country, water resources are scarce and water pollution is serious. How to obtain water environment parameters efficiently, in real time and accurately, and research and develop networked and intelligent real-time monitoring systems for water environment have become urgent. need.

[0003] The existing water environment monitoring methods are mainly divided into two types: 1) manual sampling and laboratory analysis using portable water quality monitors; 2) automatic water environment monitoring system consisting of a re...
