Online groundwater monitoring refers to the real-time and continuous monitoring of groundwater quality, water volume, water temperature and other parameters through monitoring equipment placed in groundwater, providing a scientific basis for groundwater pollution prevention and control. The demand for groundwater quality safety is growing, and groundwater online monitoring technology plays an important role in ensuring groundwater safety and improving the ecological environment.
With the rapid development of my country's economy and the acceleration of urbanization, the development and utilization of groundwater resources are increasing day by day. However, groundwater pollution has become increasingly prominent, seriously threatening human health and the ecological environment. The quality of groundwater in some areas has deteriorated, and pollution sources are complex and diverse, including industrial wastewater, agricultural non-point source pollution, domestic sewage, etc. Traditional groundwater monitoring methods mainly rely on manual sampling and laboratory analysis, which have problems such as long monitoring cycles, untimely data acquisition, and limited monitoring scope. Our government attaches great importance to the prevention and control of groundwater pollution and has issued a series of policies and regulations, such as the "Groundwater Pollution Prevention Law","Groundwater Quality Standards", etc., provide policy guarantees for online groundwater monitoring. In order to effectively prevent groundwater pollution and ensure groundwater safety, online groundwater monitoring technology emerged. Online groundwater monitoring refers to the real-time and continuous monitoring of groundwater quality, water volume, water temperature and other parameters through monitoring equipment placed in groundwater, providing a scientific basis for groundwater pollution prevention and control. The demand for groundwater quality safety is growing, and groundwater online monitoring technology plays an important role in ensuring groundwater safety and improving the ecological environment.
Real-time data monitoring: Realize map display and viewing of online monitoring, including rapid query and display of monitoring equipment, display of monitoring data, display of alarm conditions and real-time display of monitoring data curves. Through the display function of the main interface of the system, you can view the location and operating status of the equipment, and master It can monitor various indicators in groundwater in real time and continuously; Set alarm thresholds. Once an indicator is detected to exceed the standard, an alarm will be automatically issued to remind relevant departments to deal with it in a timely manner and effectively prevent the occurrence of environmental pollution incidents.
Timely alarm: Through various types of sensors installed in groundwater, relevant data such as water level height, temperature, pH value, and dissolved oxygen content are obtained. Transmitted to relevant software systems to achieve all-round real-time monitoring of the entire dam body. When the data exceeds the upper alarm limit, the system will automatically release different levels of alarm information based on the alarm data. Multi-level alarms can be set, and pop-up software window alarms, email alarms, SMS alarms and other functions can be communicated to relevant leaders and responsible persons in multiple ways.
Data analysis and prediction: High-precision sensors can accurately measure various indicators of groundwater water quality and comprehensively compare and analyze relevant data such as long-term stable operation in complex environments, historical data and other relevant data, and calculate the time and space of various dam body operation data. Correlation, comprehensive judgment of groundwater health status. It reduces possible errors and uncertainties in traditional manual sampling and monitoring, and provides reliable data support.
Digital twins: Under the premise of application, data and graphics will be integrated during the online monitoring and management process of groundwater to simulate real scenes, and the results of scientific calculations will be visually expressed through three-dimensional scene representation and dynamic forms.
Convenient operation: It has a large screen and a multi-functional input keyboard for on-site parameter setting, manual number setting, installation and debugging, status display and other functions, as well as serial port configuration methods. Supporting multiple working modes (including self-reporting, query, compatibility, etc.) to minimize power consumption, managers can more scientifically formulate development, utilization and protection plans for groundwater resources and optimize water resource management strategies.
The groundwater online monitoring system mainly consists of four core parts: data acquisition unit, transmission unit, central processing unit and user interface. Through the collaborative work of these four main components, the groundwater online monitoring system realizes real-time monitoring, data analysis and early warning of key parameters such as groundwater level and water quality, providing strong technical support for groundwater management and protection.
Data acquisition unit: Responsible for collecting data on groundwater level, water quality and other related parameters in real time to ensure the accuracy and timeliness of monitoring data. These data include but are not limited to key indicators such as water level, temperature, pH, and dissolved oxygen content.
Transmission unit: The task of sending the data collected by the data acquisition unit to the central processing unit in real time and efficiently. In order to ensure the stability and reliability of data transmission, the transmission unit usually uses wired or wireless communication technologies, such as 4G, 5G\LoRa, etc., to ensure that data will not be lost or delayed during the transmission process.
Central processing unit: It is the core of the entire system. It processes, analyzes and stores the transmitted data. The processing unit uses advanced algorithms and models to analyze the data to identify abnormalities or trend changes in the groundwater system. In addition, the central processing unit is also responsible for long-term storage of the processed data for future historical data analysis and comparison.
User interface: provides users with an intuitive and easy-to-use operating platform for displaying processed data and alarm information. Users can view real-time data, historical data charts, alarm records and other information through the interface, and perform operations such as data export and report generation as needed. User interfaces are usually designed to focus on user experience, ensuring that users can quickly obtain the information they need and respond to abnormalities in groundwater systems in a timely manner.
Online monitoring of groundwater plays a vital role in many fields such as water resources management, environmental protection, and disaster warning. By monitoring groundwater level and water quality changes in real time, it can provide scientific decision-making basis for relevant departments to better manage and protect this valuable natural resource. Promote the rational development and utilization of water resources and improve the utilization efficiency of water resources. Online monitoring of groundwater can help us better understand the distribution and reserves of groundwater resources, so as to formulate more scientific and reasonable development plans to avoid over-exploitation and resource waste. Groundwater is closely related to surface water, soil and ecosystems. By monitoring changes in groundwater, environmental conditions can be better assessed and scientific basis for ecological restoration and environmental protection can be provided, thereby achieving harmonious coexistence between man and nature.
