Description

Small local automatic weather station with adaptive water level fluctuation and its monitoring method

technical field

The invention relates to the technical field of meteorological monitoring. More specifically, the present invention relates to a small local automatic weather station with adaptive water level fluctuation and a monitoring method thereof.

Background technique

With the continuous improvement of the degree of industrialization and the progress of social and economic development, environmental problems such as air pollution, soil and water pollution, wetland degradation and global warming have become more and more prominent. Management is particularly important. Because the weather station needs to obtain the most representative meteorological data, the location of the weather station often determines its data quality and service effect. At present, most of the meteorological stations in the world are built on land, and only a few meteorological stations are built on the water surface (sea surface operation platform or river and lake observation platform). A common feature of these weather stations is that the foundation is stable and immovable, which is determined to obtain long-term, stable and reliable data.

In addition, weather stations around the world are mainly based on semi-automatic monitoring or automatic monitoring, that is, monitoring data is only stored in the weather station, requiring technicians to periodically collect and analyze data; some old weather stations have data storage functions. None of them are available, requiring complete manual monitoring and operation, and the data obtained is only instantaneous. These weather stations have not actually achieved automatic reading, automatic storage, wireless transmission and real-time analysis of monitoring data, that is, true full automation. With the continuous development of science and technology, the deepening of scientific research, and the continuous focus of scientific research scale, conventional, large-scale, fixed, large-scale, low-precision weather stations and corresponding monitoring data can no longer adapt to cutting-edge science. Research and specific socioeconomic activity needs.

At present, the 4G/5G wireless transmission terminal system plays an active and important role in the meteorological processing process, and can understand the meteorological situation in real time, objectively and accurately. With the gradual deepening and expansion of system applications, the meteorological industry system will gradually develop in the direction of digitization, networking and intelligence, and the application scope will become wider and wider. Large-scale networked local monitoring has become a development trend, using various wireless communication technologies Expanding the scope of monitoring and planning to improve rapid decision-making and emergency command capabilities, and using intelligent monitoring technology to improve the degree of automation of the meteorological monitoring system will become an important feature of the future meteorological monitoring system.

At present, my country is vigorously promoting the construction of ecological civilization and coordinating the protection of the ecosystems of mountains, rivers, forests, fields, lakes and grasses, which requires high-precision meteorological and environmental monitoring data as support. In some small-scale fine studies of riparian wetlands, lake ports, and aquatic ecology, indicator data such as water surface evaporation, water plant and crop transpiration are very important. If data from local weather stations are used, the accuracy is often not high, and the error is large. However, if a small weather station is built on the land near the water body, it may be affected by the unfavorable site selection and the discrepancy with the real situation.
