Abstract

The invention relates to a water quality environmental monitoring system based on wireless transducers. The technical problems of how to monitor the water quality in real time and how to automatically store and process monitored data are solved. The system comprises: wireless transducer nodes installed underwater for water quality monitoring; convergent nodes and a GSM transmission module arranged on a water surface, wherein the convergent nodes receive data collected by cluster member nodes in a water area in a certain range, perform data fusion, and send the processed data to the GSM module, which transmits the received data to a central information control center; and the central information control center for receiving, analyzing and processing information reported by the distributed convergent nodes and sending control signaling to the convergent nodes with different ID for indirect real-time monitoring and data acquisition of transducer nodes. The system has beneficial effects of low power consumption, simple network structure, reduced message collision, and increased network capacity.

Description

technical field

[0001] The invention relates to the technical fields of wireless communication, wireless sensors, water quality monitoring, GPS and ZigBee, in particular to a water quality environment monitoring system based on wireless sensors. Background technique

[0002] Water quality monitoring is an important basis for water resources and environmental management and protection, and an important means of protecting the water environment. The monitoring and governance of water quality is related to the production of all walks of life and people's lives. The environmental water quality online monitoring system is a water quality online monitoring wireless sensor network set up in rivers, lakes, reservoirs, drinking water sources, sewage discharge outlets and other areas. At present, there are still many problems in my country's water quality testing. First, the sampling capacity of water quality monitoring centers at all levels is insufficient, the monitoring frequency ...

Examples

Embodiment Construction

[0021] To estimate which water quality parameters need to be monitored in the monitoring waters, monitor the water quality, including basic parameters such as PH value, DO, turbidity, water temperature, conductivity, ammonia nitrogen, TOC, COD, etc., and then make corresponding sensor nodes.

[0022] A water quality monitoring base station should be established near the water area to cache the water quality parameters collected by the sink nodes from the sensor nodes, and transmit data to the central control information center at regular intervals.

[0023] Divide the water area, select the appropriate distance to divide the water area according to the maximum distance that the sink node and the sensor node can communicate, and put the corresponding sensor nodes in the water area.

[0024] The sink node is fixed in the middle of the exchange area, and the AODV (AdHocondemanddistancevector) algorithm is used to establish routing information and communicate with trusted sensor no...
