Description

Technical Field

[0001] The present invention relates to the technical field of Internet and intelligent agriculture, and in particular to a river water quality remote monitoring system based on Internet. Background Art

[0002] With the rapid development of industrialization and urbanization, rivers, as important freshwater resources on the earth, have a water quality that is directly related to human living environment, ecological balance and economic development. However, rivers face threats from industrial wastewater, domestic sewage, agricultural non-point source pollution, etc., which lead to water quality deterioration and even serious environmental incidents. Traditional water quality monitoring relies on manual regular collection of water samples and detailed chemical and biological analysis in the laboratory. Although this method can provide accurate water quality data, it is time-consuming, labor-intensive, costly and unable to achieve real-time monitoring. Water pollution not only destroys the balance of aquatic ecosystems, but also has serious impacts on human drinking water safety, agricultural production and leisure and entertainment. The current number of water quality monitoring points is relatively small, and it is difficult to fully reflect the water quality of the entire water area. The uneven distribution of monitoring points may lead to inaccurate and incomplete monitoring data, and cannot provide strong support for environmental decision-making. Especially in some remote areas or areas with complex water quality changes, the lack of monitoring points makes it difficult to monitor water quality in a timely and effective manner. The existing water quality monitoring indicators are relatively few, mainly focusing on conventional water quality parameters such as temperature, pH value, dissolved oxygen, etc. However, the monitoring of some emerging pollutants and harmful microorganisms is still inadequate, and these pollutants may pose a potential threat to human health and the ecological environment. Therefore, the existing monitoring indicators are difficult to fully assess the environmental health of water bodies. The current water quality monitoring equipment and technology level are relatively backward, which affects the accuracy and reliability of monitoring data. The sensitivity and discrimination rate of some equipment are insufficient to fully meet the monitoring requirements of trace pollutants. The amount of data generated by water quality monitoring is huge, but the current data transmission and storage are chaotic. The lack of unified data standards and sharing mechanisms leads to low data utilization, which limits the application and effect of water quality monitoring data in environmental protection and water resources management.

[0003] Therefore, an Internet-based remote monitoring system for river water quality is proposed. Summary of the invention
