The Four-Faith Hydrological Intelligent Monitoring System Assists in Upgrading Hydrological Stations

Hydrological work is a fundamental task for modern economic and social development. China has entered a new stage of development, and the increasing demand of the people for safety in water and drought disaster prevention, as well as for good water resources, water ecology and water environment, have put forward higher requirements for hydrological work. It is necessary to accelerate the modernization of hydrology. In 2021, the "Plan for the Modernization of Hydrology Construction" and the "14th Five-Year Plan for the Construction of National Hydrological Infrastructure" have clearly defined the direction, ideas, goals, and tasks of hydrological development. Provincial-level water administrative departments have accelerated the construction of a modern hydrological system that is synchronized with the development of the times in terms of technology, and adapted to the needs of the times in terms of service capabilities, from improving the national hydrological station network, promoting hydrological monitoring automation, promoting real-time hydrological forecasting, warning and simulation, and promoting intelligent hydrological information analysis and evaluation. This will provide reliable support for high-quality development of water conservancy.

Needs Analysis

Currently, the main problems with national basic hydrological stations, water level stations, and rainfall stations are as follows:

The infrastructure of hydrological monitoring stations is old and non-standard, with damages and losses, which urgently need to be rectified and renovated.

Some hydrological monitoring stations have been in service for many years, with outdated equipment. Most of the hydrological data is manually collected and observed, which cannot achieve full-element, full-range, and fully automatic monitoring.

The information transmission technology of some stations is outdated, and there are problems with signal quality, untimely information reporting, and insecure storage and transmission of information.

Solution

Establish various hydrological observation sites in rivers, lakes and watersheds, deploy automated monitoring stations for hydrological elements, and rely on modern high-tech such as the Internet of Things, wireless communication, remote sensing, and telemetry. Through perception and collection of hardware devices, real-time collection, storage, reporting and processing of hydrological data such as water level, precipitation, flow, velocity, water quality, as well as images and videos in river basins, effectively improve the intelligent level of hydrological station management, provide scientific basis and effective information sharing for flood prevention, drought resistance and disaster reduction, ensure the safety of people's lives and property, and meet the needs of hydrological services for water resources and socio-economic development.

Site Construction

Water level video observation the water level video observation site is composed of radar water level gauges, submersible water level gauges, floating ball water level gauges, and video cameras, which can grasp the dynamic changes of hydrological conditions in a timely manner.

Flow Monitoring

Flow monitoring stations consist of radar flow meters and ultrasonic flow meters, which enable real-time and accurate monitoring of river flow rate and velocity.

Meteorological Observation 

Comprehensive monitoring and analysis of parameters such as precipitation, rainfall, evaporation, wind direction, and temperature for each station and sub-basin, supporting disaster meteorological early warning, assisting managers to fully understand the hydrological and meteorological situation, achieving accurate weather prediction and timely response.

Solution Advantages 

Comprehensive Data Collection of Monitoring 
Through the front-end intelligent sensing terminal, 24-hour comprehensive intelligent hydrological element collection is supported to meet the monitoring needs of various scenarios, which is of great significance for optimizing the layout of the existing monitoring station network and improving the water resources monitoring system.

Significantly Enhanced Perception Capability 
Opening diversified interfaces to realize intelligent access of IoT devices, supporting multi-element monitoring at one station, and super-threshold forecast and early warning. Real-time and multi-angle monitoring of equipment status can be achieved through image and video, which greatly enhances the comprehensive perception capability of hydrology.

Solution to Save Manpower and Materials 
Traditional manual sampling observation is time-consuming and laborious. Through automatic monitoring equipment, remote and comprehensive monitoring and unified equipment management can be achieved, reducing labor costs, and lowering material consumption.
