Research On Water Environment Detection System Based On ZigBee Wireless Sensor Network

With the development of the society,China's economy and manufacturing industry are gradually pushing forward,and the urgency of ecological environment construction is increasingly prominent.Among them,the problem of water pollution is particularly prominent.Water pollution seriously restricts the sustainable development of social economy and even threatens the health and survival of human beings.Therefore,it can avoid the deterioration of water pollution by understanding the situation of water quality and quickly discovering the trend of water quality deterioration.Therefore,it is necessary to monitor the water quality of reservoirs,lakes and wetlands online.At present,the leading technology of water environment monitoring is the use of wireless sensor network.Because Zig Bee technology has the characteristics of low cost,low power consumption and low complexity,Zig Bee technology is widely used in wireless sensor monitoring system.This design organically combines the requirements of water quality monitoring sensor nodes with the theory of Zig Bee wireless transmission technology.Based on the Zig Bee technology,a design method of water quality monitoring sensor nodes for water environment monitoring system of wireless sensor network is proposed.Real-time monitoring of the water environment is the main purpose of the design.In particular,the data of the water environment is acquired through each sensor module,and the monitored data is sent to the aggregation node by using the Zig Bee protocol.This paper introduces the overall design of the sensor node in the water quality monitoring system,and introduces the design of hardware and software and the improvement of routing algorithm in detail.In terms of hardware,TI group's Zig Bee chip based on CC2530 standard is selected as the main chip developed in this design.The line sensor node USES the corresponding sensor module to realize the collection of water quality parameter information.In terms of software,this paper introduces the IAR EW integrated development environment,completes the programming task,and gives the flow chart of each node.In terms of algorithm,an improved LEACH algorithm based on ant colony algorithm is proposed and simulated.Simulation results show that the routing established by the algorithm can effectively reduce the energy consumption of the whole wireless sensor network during signal transmission and reception,and extend the service life of the whole network.Through the testing of each module and the whole,this design has realized the data collection of important parameters such as water temperature,PH value,conductivity,turbidity and dissolved oxygen,and also completed the data transmission of each node under the Zig Bee technology,realizing the basic functions of the system and meeting the basic requirements of the design.Compared with the traditional water quality monitoring method,this design improves the monitoring efficiency and realizes more effective real-time monitoring.
