Water quality monitoring system based on ZigBee

Abstract

The invention discloses a water quality monitoring system based on ZigBee, comprising a terminal node acquisition unit, a ZigBee coordinator unit and a remote data monitoring unit which are connectedin sequence. The terminal node acquisition unit includes a sensor module, a first microprocessor, and a plurality of ZigBee nodes; the sensor module includes a pH sensor for detecting water pH and a temperature sensor for detecting water temperature; the sensor module is connected with the first microprocessor via an interface circuit. Water quality data acquired by the terminal node acquisition unit is transmitted and monitored in real time through the ZigBee network and the wireless communication network; the data is transmitted to a cloud server through the wireless communication network. One or more terminal node acquisition units may be provided herein; ZigBee nodes and the ZigBee coordinators may be automatically networked via the ZigBee network; therefore, the system herein is highly flexible and applicable, can provide intelligent control for monitoring, can provide multipoint sampling to allow wireless communication, and allows information to be transmitted conveniently in real time.

Description

technical field [0001] The invention relates to the technical field of water quality monitoring, in particular to a ZigBee-based water quality monitoring system. Background technique [0002] With the rapid development of the economy, global water pollution, excessive consumption of water resources and improper management have caused a sharp decline in the quantity and quality of available water resources. With the change of people's living standards and life concepts, people's environmental The requirements are getting higher and higher, and environmental problems have begun to be valued by the society. Therefore, the construction of water quality monitoring networks has been mentioned in the prominent position of urban infrastructure construction. The existing water quality monitoring systems are mostly in the stage of manual monitoring or wired monitoring, which can be expanded. The performance is poor, it is not convenient for multi-point collection, and it cannot meet t...
