Design And Implementation Of The Groundwater Remote Monitoring S Ystem In The Pilot Area Of Wuzhou-zhaoqing Section

This topic is derived from a part of basic research of "1:50,000 environmental geological survey in Wuzhou-Zhaoqing pilot area of Zhujiang-Xijiang economic belt",a development project commissioned by Wu Han geological survey center.China's groundwater accounts for one third of the country's available water resources.Due to its good water quality and stable water quantity,groundwater is a high-quality water supply source for urban water,industrial and agricultural water.Groundwater not only provides important water resources for human development,but also has some harms.For example,when water contains too many sulfate ions and free oxygen plasma,it will erode the underground structure of buildings.Therefore,the rational use of groundwater resources is related to people's life and national development.In the early years,people's awareness of groundwater protection is not strong,long-term over-exploitation,improper treatment,so that the groundwater resources are damaged,and even the land subsidence,land salinization and other conditions.Information-based monitoring is of great significance for the scientific management and sustainable development and utilization of groundwater resources.This paper designs a set of in view of the xijiang river basin wuzhou-zhaoqing area of groundwater monitoring system,to understand whether the monitoring area groundwater drinking water standard,the self-purification ability of groundwater,groundwater polluted situation and terrain real-time monitoring scope change,respectively for monitoring groundwater PH,solvent dissolved oxygen,temperature,water level,rainfall collection and monitoring;Through the monitoring web page to remotely view the data information of each monitoring point,and can generate statistical data,monitoring reports and graphics.This system can monitor the groundwater in the test area for a long time,provide data support for the protection and planning of the test area,and set a good example for realizing the comprehensive automatic groundwater monitoring in xijiang river basin.This paper firstly introduces the background of the subject and the development status of groundwater monitoring at home and abroad.After analyzing and comparing the advantages and disadvantages of various monitoring technologies,and investigating the monitoring site environment on the spot,the overall design scheme of the groundwater remote online monitoring system is put forward.It also introduces the main functions of the system,its working principle and three key technologies,namely WEB technology,Web GIS technology based on baidu map API and database,which are needed to design the system.Then it introduces the design and compilation process of monitoring equipment hardware,monitoring platform webpage and database in detail,and then gives an example of system operation.Finally,the paper summarizes the characteristics of the system and the problems encountered in the research and development process,and forecasts the future development of the system.At present,the system has been put into use in the project of "1:50,000 environmental geological survey in wuzhou-zhaoqing pilot zone of the zhujiang river xijiang economic belt".The whole system has been running stably with reliable data and has basically reached the expected target.
