Introduction
The automatic hydrological monitoring and forecasting system is the application of telemetry, communication, computer, Internet of Things, big data, cloud computing and other technologies to complete the watershed or survey area.
Precipitation, evaporation, water level, flow rate, sediment content, water quality, moisture content, tide level, wind direction and speed, gate opening and other hydrometeorological,
It is an intelligent information system for data collection, transmission, processing, management and application of water conservancy project working condition elements. With intelligence as an important symbol
With the advent of the fourth industrial revolution in the world, the automatic hydrological forecasting system integrates multi-professional, multi-disciplinary, and multi-field technologies, and is used in water conservancy, electric power, marine
It has been widely used in many industries such as ocean, meteorology, environmental protection, agriculture and forestry, industrial and civil construction, etc. in my country's hydrology, water resources, water environment, water ecology, engineering safety, etc.
It has played an important role in environmental protection, drought, water-saving agriculture, smart grid, smart water, urban pipe network, etc., and has significant decision-making support effects.
It is also a kind of comprehensive system engineering, and it needs a unified standard to guide its construction and application, so it is proposed to compile this document.
In the preparation of this document, a large number of domestic and foreign technical literature and related standards on hydrological automation have been consulted, and the current
The latest communication technology, Internet technology, sensor technology and other automation and intelligent technologies are used in water conservancy, resources, environment, agriculture and forestry, electricity, meteorology and other industries.
The results of mature applications in the industry field, the topology structure, system technical requirements, hardware equipment (including sensors) of the hydrological automatic forecasting system
Requirements, installation and commissioning, trial operation assessment, operation and maintenance management, pre-construction, data transmission protocols, etc. make unified regulations, and the automatic hydrological test
The whole process of reporting system construction has been standardized, taking into account the purpose, advanced nature of system construction, forward-looking technology, and practicality of standards.
It has a positive impact on regulating the application of automatic monitoring and forecasting technology nationwide, and has a positive impact on improving the level of automatic forecasting and forecasting technology at home and abroad.
significant.
In the preparation of this document, combined with the actual application of the hydrological automatic forecasting system, according to the requirements of the project construction, in the planning, design, construction
Uniform provisions have been made in terms of design and management; for new products and new equipment with reasonable design and advanced technology in their application, it is necessary to ensure the reliability of the system.
On the premise of safety, on-site assessment and application are encouraged, and further promotion after successful use.
