Design And Implementation Of Intelligent Water Quality Monitoring Platform Based On Wireless Sensor System

As we all know,people's life is inseparable from environmental factors.Common factors such as atmosphere,water sources or geology affect our quality of life and even our survival.Facing the increasingly severe environmental situation,we must take action.The research in this paper aims at the water resources in the environment and realizes the real-time monitoring of the remote source water quality by the upper computer.The monitoring of the environment is urgent,only the real-time understanding of the environmental dynamics.In order to take timely action to mitigate or avoid the occurrence of disasters,environmental monitoring is of special significance in scientific research,which includes collecting environmental parameters from the real environment,and intelligent analysis of the collected data in order to control and improve forward.This topic relies on the Tianshui science and technology support plan project: the intelligent environment monitoring platform,aims to realize the water quality environment information and provide the real-time,the security as well as the monitoring aspect request,devotes to the establishment of a comprehensive utilization sensor equipment,the system integration technology and development of computer software platform with independent intellectual property rights form an intelligent integrated environment monitoring platform with multi-area field sampling,network remote data transmission and software control and analysis.And the project has been approved by the Science and Technology Bureau on December 10 th,2017,formally put into production.This paper mainly studies the intelligent water quality monitoring based on wireless sensor system,and realizes the mastering and judging of physical environment factors by control terminals.The main research contents:(1)Hardware circuit module.The design includes core board,sensor conditioning module,power module,communication module and related interface.Microprocessor module and RF transceiver module are designed based on CC2530 chip,according to the output characteristics of different sensors,design the corresponding conditioning circuit.(2)Communication module.It is necessary to complete the communication between the ZigBee node and the other node in the wireless sensor network and the communication between the ZigBee and the GPRS of the sink node.(3)Data warehouse.The realization and fusion of ROLAP technology and data mining algorithm can not only display the data multidimensional,but also mine more data information.(4)Android mobile terminal.Add WIFI module to remote monitor the temperature,humidity and other real-time data.The mobile phone display at the same time generate a table file,from the mobile phone SD card to the PC side.(5)Web terminal.Through the technology of ASP.Net three-layer architecture,the system terminal will set up,and the data of each collection point is viewed from the web terminal and the corresponding warning is made.The main innovations of this paper are:(1)Data warehouse.Using ROLAP technology and data mining analysis technology,the data collected from different test points are loaded into the data warehouse,and the powerful ability of data integration is realized.It provides data support for analyzing the actual situation of monitoring area.(2)Interactive Web applications.This paper introduces several new technologies,such as Boot Strap(front-end frame CSS3.0 / HTML5)into the design.By integrating these technologies,a unique adaptive user interface system is developed,which can present a new interactive experience from mobile to PC.(3)Data analysis and sharing.Through Internet technology,the data of different regional monitoring points can be gathered,so that clients can query on the platform.This part distributes the application of cloud computing technology to the sharing of data resources in various places,and big data's analytical ability provides scientific basis for the key decision-making stage.(4)Modular component application.The platform framework consists of core layer,data layer,model layer and business logic.It can be dynamically scheduled by the core layer according to the permissions of different roles.Modularization also provides the possibility for the scalability of the platform function in the future.(5)Advanced technology application.In order to make the software ahead of the similar software,the multi-channel concurrency technology adopted in this paper has changed the performance bottleneck of the former queue type,realized the choice of the data queue,and made the data analysis.The transmission efficiency of filtering and storage has been further improved,which accords with the new development direction of Internet applications.
