Automatic monitoring system of water and rain, an important means of flood and drought disaster early warning

As an important means of flood and drought disaster early warning, the automatic monitoring system of water and rain is of great significance to the realization of water resources security. Like the automatic weather station, it has the functions of data collection, analysis, processing and early warning. It is widely used in water conservancy projects, mainly for flood control and emergency rescue of reservoirs, hydropower stations and other projects.

Water and rain automatic monitoring technology is a modern high-tech based on computer technology. The automatic monitoring system is a real-time dynamic information acquisition device composed of computers and various sensors. Its working principle is:

(1) Select appropriate sensors according to the actual situation on site;

(2) After the required information is transmitted to the upper computer or server, the corresponding screen is used for data processing and display, and can be transmitted to relevant sites through the network.

With the development of social economy and the improvement of people's living standards, people pay more and more attention to the construction of water conservancy facilities and have higher requirements for flood control and waterlogging drainage. Therefore, how to effectively prevent floods and do a good job in flood control and disaster reduction has become an urgent matter.

The automatic monitoring system of water and rain is a new intelligent product to solve these problems. It can timely and accurately grasp the change of hydrological data and provide basis for leaders at all levels to make decisions. It can also be used to carry out water conservancy construction management and promote scientific operation and management of water conservancy departments. Compared with traditional manual observation, it has the following advantages:

（1） No manual intervention is required;

（2） Not subject to weather conditions;

（3） It is not limited by the number of objects to be tested, and can run continuously without interruption.

Due to the modular design of the equipment, it is easy to maintain and replace. At present, automatic monitoring system of water and rain has been used in many areas of China. Small size, light weight, convenient installation and maintenance, moderate price, so it is easy to promote and apply to various water conservancy projects and other fields.
