Research on key technologies and applications of intelligent deformation monitoring for measurement robots

Abstract

With the continuous high-quality promotion of water conservancy infrastructure construction and management in our country, ensuring the safety and stable operation of these projects has become a key point. Focusing on the pain points of the traditional multi measurement robot operating mode without networking, a smart deformation monitoring system based on the integration and collaboration of multiple measurement robots is proposed, aiming to greatly improve the accuracy and reliability of monitoring through real-time meteorological field model correction and real-time network adjustment technology. The integration and collaboration challenges of multiple measurement robots in an intelligent deformation monitoring system were overcome, achieving barrier free communication between robot devices and reasonable task allocation, effectively improving the overall efficiency of the system. We have successfully developed a real-time meteorological field model that can accurately obtain and utilize atmospheric parameters to finely calibrate ranging data, thereby significantly reducing the impact of environmental factors on measurement result. We have developed real-time network adjustment technology to ensure the efficiency and accuracy of data processing. The system has been successfully applied in the safety monitoring of many major water conservancy projects such as the Three Gorges Dam, Danjiangkou Dam, Xiluodu Hydropower Station, Wudongde Hydropower Station, Baihetan Hydropower Station, and South to North Water Diversion Project. The monitoring accuracy of the system has reached ± 2.0 mm, which not only significantly improves the intelligent level of engineering operation and maintenance, but also provides strong technical support for the safety management of key infrastructure. The research result have filled the technological gap in the industry, provided valuable experience and reference for similar water conservancy project safety monitoring, and also promoted the development of infrastructure monitoring technology in China to a higher level.
