The degree of reservoir safety has always been the difficulty and focus of flood prevention and flood control in our country. Most small and medium-sized reservoirs lack necessary facilities such as water and rain forecasting and dam safety monitoring. The inspection methods are backward and the hidden dangers are huge. The reservoir safety problem needs to be solved urgently.
The DIT-DAMS-3000 Medium and Small Reservoirs Integrated Information System realizes automatic monitoring of rainfall, water level, dam seepage pressure, seepage, and saturation line reservoirs, providing timely and accurate information for the safety management and operation of the reservoir, and timely warning. Provide the basis for relevant departments and leaders to make scientific decisions and improve the efficiency and quality of reservoir project management.
The small and medium-sized reservoirs integrated information system adopts advanced technology such as distributed dam safety monitoring and close-range wireless communication network, effectively reducing costs and improving system reliability. It is suitable for information construction of small and medium-sized reservoirs and reservoirs for monitoring risk-removing reinforcement and supporting informationization.
System Overview The small and medium-sized reservoir comprehensive information system consists of four parts: the on-site measurement part, the remote terminal acquisition unit MCU, the dam safety data acquisition system, the information processing inquiry and release system, and the reservoir rainfall, water level, and dam Osmotic pressure, seepage, dam seepage lines and other automatic monitoring. It provides timely and accurate information for the safety management and operation of reservoirs, timely warning and discovery of potential safety hazards in dams, and provides a basis for relevant departments and leading scientific decision-making to improve the efficiency and quality of reservoir project management.

The instruments used in the project include DIT-MCU hydraulics and dam monitoring devices, data loggers, hydraulic pressure gauges, water level gauges, bar gauges, joint gauges, settlement gauges, inclinometers, water quality detectors, and GPS positioning systems. Data transmission processing system, data storage, early warning system, etc.
The small and medium-sized reservoirs comprehensive information system can realize remote automatic monitoring all-weather, collect and record the data of the sensor monitoring points in real time to relevant databases. Therefore, the data change process of the monitoring object can be completely recorded. It adopts a hierarchically distributed open structure and the operation mode is a decentralized control mode. Each local monitoring unit can be instructed to automatically conduct inspections and store data according to the set time and submit data to the monitoring center. The data acquisition system processes the analyzed data and stores it in the designated primary and standby databases.
Functional characteristics Real-time remote monitoring of the dam's various test parameters, can be set according to the need to collect the frequency, measuring point data, the original data can be calculated in various ways.
The data can be saved in various databases and can be used to query historical data. It can also directly classify Excel data or other forms of reports.
The data can be graphically displayed, including water level flow relationships, water level process lines, rainfall histograms, osmotic pressure, seepage process lines, time history plots, X/Y plots, simulation plots, histograms, and histograms.
With data over-limit alarm function, water level exceeding limit water level alarm and water level fluctuation rate over limit alarm, when the site uploads alarm information instantly, the host will have obvious alarm screen and alarm information.
Automatic collection of rainfall, water level and other hydrological information, osmotic pressure, seepage and other dam monitoring information, to achieve automatic monitoring of reservoir dam saturation line.
Adopting standardized, open design and standard MODBUS communication protocol, it can access general industrial control configuration software or special security monitoring software, adopt close-range wireless network or GPRS/CDMA communication, and reduce the difficulty of implementing the safety monitoring system.
The distributed system structure has a high degree of reliability and economy. The data acquisition units are distributed near the sensor installation site. The reliability and stability of the system are greatly improved, and the amount of signal cables can be greatly reduced. The economic efficiency of the system is greatly improved. The implementation and maintenance of the project are more convenient.
