With the acceleration of urbanization, the protection and utilization of water resources has become an important issue for social development. As a new generation of information technology, smart water is an in-depth application in the field of water affairs, which provides new ideas for solving water resource management problems. Among them, the reasonable arrangement of monitoring points is the key link to realize smart water affairs. This article will explain how to scientifically and reasonably arrange smart water monitoring points.
Principles of monitoring point layout.
Comprehensive coverage: The layout of monitoring points should cover the entire water area to ensure that there are no dead ends in real-time monitoring of water quality.
Highlight key points: For key areas such as pollution sources and drinking water sources, monitoring should be strengthened and the frequency of monitoring should be increased.
Easy maintenance: Choose a monitoring point with superior geographical location and convenient transportation, which is convenient for the installation, commissioning and later maintenance of the equipment.
Scientific layout: Follow the relevant principles of hydrology, environmental science and other relevant principles to ensure the accuracy and representativeness of monitoring data.
Methods of monitoring point layout.
Based on water quality type: according to different water quality types, such as drinking water sources, industrial wastewater outlets, agricultural irrigation areas, etc., set up corresponding monitoring points.
Based on the river trending arrangement: monitoring points are set up in the upstream, middle and downstream of the river to analyze the trend of water quality change and pollutant migration.
Grid distribution method: The grid distribution method is used in key areas, that is, monitoring points are arranged at a certain distance in a certain area to achieve comprehensive monitoring of water quality in the area.
Remote sensing and GIS technology assistance: Remote sensing and GIS technology are used to conduct spatial analysis of water areas and determine the optimal monitoring points.
Monitor the implementation steps of the site.
Needs analysis: Clarify the purpose of monitoring, the scope of monitoring, and the type of data required.
On-site investigation: Conduct field investigation of the target water area to understand the actual situation such as hydrology and topography.
Preliminary selection of points: According to the demand analysis and on-site investigation results, the monitoring points are preliminarily determined.
Optimization and adjustment: use technical means to optimize and adjust the primary selection points to improve the monitoring efficiency.
Implementation and construction: equipment installation, commissioning and data acquisition system construction are carried out according to the determined monitoring points.
Post-maintenance: regularly inspect and calibrate the monitoring equipment to ensure data accuracy; According to the actual needs, the monitoring points should be adjusted in a timely manner.
The layout of smart water monitoring points is an important part of realizing smart water affairs, and it is necessary to follow the principles of comprehensive coverage, highlighting key points, easy maintenance and scientific layout. In practice, the monitoring points should be determined according to the classification of water quality types and the layout of river directions, and remote sensing and GIS technology should be used to assist in optimization. In the process of implementation, it is necessary to clarify the requirements, conduct on-site investigations, optimize and adjust, and pay attention to post-maintenance. Through the scientific and reasonable arrangement of monitoring points, the monitoring ability of smart water can be improved, and strong support can be provided for the protection and utilization of water resources.
