Introduction to automatic rainfall and water level monitoring station

Rainfall and water level are important factors affecting reservoir safety. As an indispensable part of rainfall observation system, automatic rainfall level monitoring station plays a very important role in flood prevention. There are some problems in the traditional hydrological forecasting methods, such as the inability to timely and accurately monitor the amount of rainfall, and the inability to achieve real-time update of rainfall information. In view of the above shortcomings, the intelligent water level monitoring system based on wireless sensor technology is a large field, which can not only provide users with more accurate and intuitive data acquisition and processing services, but also meet the application requirements of various needs.

The functions of automatic rainfall and water level monitoring station mainly include the following aspects:

1) The wireless sensor network is used to communicate the field measurement results with the host computer;

2) Obtain relevant parameters through RS-485 protocol and transmit them to the computer;

3) Calculate the flow value of each station according to the obtained data;

4) The corresponding warning curve is generated according to the obtained flow value.

The construction of automatic rainfall and water level monitoring station has a very positive significance for improving the utilization rate of water resources, and is also an effective measure to reduce flood disasters and prevent water damage accidents. Because the wireless sensor network can receive the data sent by multiple stations at the same time, the device has high communication efficiency and can be conveniently installed at any location.

The data storage of automatic rainfall and water level monitoring station adopts distributed storage technology, which can save historical rainfall data and current rainfall at any time, thus greatly improving the data storage efficiency.
